Ryan introduces co-host Holly Knotowicz.   [1:07] Holly introduces today's topic: eosinophilic esophagitis (EoE). EoE is a chronic allergic inflammatory disease of the esophagus.   [1:19] EoE occurs when eosinophils, a type of white blood cell, accumulate in the esophagus in elevated numbers, causing inflammation that can make eating or swallowing difficult or uncomfortable.   [1:30] Holly introduces and welcomes today's guest, Amarah, a high school student who is a patient advocate living with EoE. Welcome, and thanks for joining us.   [1:37] Amarah thanks Holly and Ryan and says she is very excited to be here.   [1:50] Amarah says she is a high school senior. She loves to perform and act. She is also very involved in sports and school activities. She is a cross-country member and a soccer member.   [2:05] Amarah was diagnosed with EoE when she was very young. She has done every treatment you can think of. She has had foods that she was able to eat, and then she couldn't eat them, and then later she could go back to eating them.   [2:19] Amarah says it feels like she has had "millions and millions" of scopes. She has done transnasal scopes and regular scopes.   [2:28] Holly says she and Ryan have been on numerous types of therapy and tried diet elimination. Holly has done the transnasal scope and is excited to hear that Amarah has. Ryan says he feels left out and needs to try a transnasal scope at some point.   [2:52] Holly says we also call it a nonsedated endoscopy. Holly says she loves that Amarah has access to it. Amarah says her state is sparsely populated without those resources, so she flies down to Phoenix, where she used to live, for all of her doctoring.   [3:27] Holly says it's awesome for listeners to know that Arizona is a state where they can get treatment.    [3:47] Amarah says she had a wonderful primary care doctor when she was little. She was having problems around eight months old. At about a year-and-a-half, her primary care doctor suggested she be tested for this "new" disease, EoE. So she got tested.   [4:16] Amarah remembers "not being able to eat anything." That was her normal. She doesn't remember having to take out any foods. The first time she realized she had something more than allergies, she was around 5 or 6 years old.   [4:37] At that time, she realized that something was not the same with other kids who have allergies. What she had was different from a normal allergy.   [4:50] Amarah says she was about 10 or 11 years old when she had a better understanding of what EoE was, inside the esophagus.   [5:16] Ryan compares Amarah's experience to his own, as he was also diagnosed very young. For years, he explained it away as allergies. It's a complicated thing to grasp when you're younger.   [5:45] Amarah is on dupilumab, which is helpful for her eczema, which has resisted topical treatments. Dupilumab also helps with her EoE, so now she is able to have dairy, wheat, and soy. She can't eat them at the same level as people who do not have EoE.   [6:27] Amarah says she prefers a lot of foods that do not have dairy and wheat in them. It's helpful for traveling. She can eat dairy, wheat, and soy, and her scopes come back clean, which is nice.   [6:44] Amarah says that in the past she has done budesonide. She is on PPIs. She had Nissen fundoplication. She also did a drug trial. When she was 12, her EoE got bad. She did a drug trial for an IV drug, and it did not work. She had an adverse reaction.   [7:24] Ryan says he was taking a medication for eosinophilic asthma, which was helping his EoE a little bit, but not a lot. Now that he is taking dupilumab for EoE, that is also helping him with his eosinophilic asthma. Ryan agrees that it is such a game changer.   [7:58] Amarah says she doesn't have other trigger foods, but she is allergic to shellfish due to IgE, not EoE. Peanuts and tree nuts trigger anaphylaxis. Soy, wheat, and dairy are definitely EoE triggers. She used to have to avoid corn but is able to have it now.    [8:38] Amarah says you just know when you eat too much of a food, and your EoE is starting to act up again.    [9:15] Ryan advises listeners to double-check with your care team before you start to introduce triggers back into your diet.   [9:26] Holly says this is so relatable. Holly is significantly older than Ryan and Amarah and didn't get diagnosed until she was older. She loves how Amarah articulated the different paths she has been on as she was growing up.   [9:55] Holly notes that Amarah was at the rise of new treatments that could give her hope to try.   [10:07] Holly asks Amarah to explain to listeners the Nissen fundoplication. Amarah says she had it when she was about four, for her GERD, which is acid reflux. She says some kids with EoE have it done; some do not.   [10:50] Amarah says the sphincter between her stomach and esophagus didn't fully close. The doctor said he had never seen a sphincter look so bad.   [11:04] They did surgery to take a part of the stomach and sew it up so the sphincter closes when food goes down the esophagus, so it stays in the stomach. Amarah says you should not be able to throw up after the surgery, but she still has that ability.   [11:42] Amarah says the surgery can get looser over the years. She has had a couple of tests where the doctors monitor how loose it is.   [11:50] Holly thanks Amarah for articulating what Nissen fundoplication is. Holly is fascinated that Amarah is still able to vomit. That's an important thing to think about with EoE. Holly had the same procedure twice before they knew she had EoE.   [12:53] Amarah says EoE has a lot of layers. It's very complicated. It's very hard to describe it. It takes a lot of extra steps [to manage it].   [13:05] Amarah explains using another diagnosis she has: mild dyslexia. She has to put in more effort and work to do school assignments because she's in advanced classes that require a lot of reading, writing, and spelling.   [13:25] EoE is similar in the way that you have to have the extra steps in order to manage it. She wishes people would know that it's a multi-step process. It's not just one and done.   [13:38] Amarah has been looking at colleges. One of the things she is looking for is whether they have cafeterias she can use. Do they have a disability program she can use and get accommodations for her needs? Do they have a kitchen she can use?   [13:57] Amarah says even though she can have all these different foods, she is still anaphylactic to peanuts and tree nuts. Because EoE can randomly flare up, it's important to her that she has those options.   [14:11] Amarah says EoE is very layered, and she wishes people would understand that more. It would be more helpful for the level of acceptance and understanding, overall, of having EoE, especially as a teenager.   [14:34] Ryan says that when he started college, he sat with the university dining hall and the office of disability services to explain his EoE, EoE triggers, and anaphylactic allergies, and to ask if he could eat at the dining hall. They offered the salad bar.   [15:03] The dining hall couldn't accommodate his needs, so he was able to get a dorm with a kitchen so he could prepare his own food.   [15:18] Ryan hopes that 10 years after Ryan started college, the university Amarah chooses will be more understanding of EoE and other allergies.   [15:56] Holly says that as a speech pathologist, she sees people with all diagnoses. There are still schools that don't consider EoE a disability. It's very important to think about accommodations. A patient chose to change schools because of the lack of accommodations.   [16:36] Holly is 42. When she went to school, she didn't know she had EoE, but she had IgE-mediated food allergies, threw up often, and could only eat certain things prepared certain ways. The school said she could eat at one dining hall, but it still wasn't safe.   [17:00] Holly says it has changed in a good way, but in some places, it has not, because some people still don't understand.   [17:11] Holly talks about Amarah avoiding corn and different things. People don't realize you can have an EoE trigger to very different types of foods, not just ones that you are IgE allergic to and need an EpiPen® for. That was key information for Amarah to bring up.   [17:35] Amarah enjoys participating in her school's speech, debate, and drama team. She used EoE as the topic for her informative speech project. Holly watched a video of it, and it was amazing. Holly asks how Amarah came up with the topic.    [19:16] Amarah says that the previous year she had done an informative speech on the history of My Little Pony, of which she is a fan. She decided that for the next year she would do an informative speech on one of the six chronic illnesses she has.   [19:56] Amarah considered which of her illnesses affected her the most. She picked EoE to learn more abo

Co-hosts Ryan Piansky, a patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Science Advisory Council, interview Timothy Buckey, MD, MBE, an allergy and immunology attending physician with a joint faculty position at the Hospital of the University of Pennsylvania and the Children's Hospital of Philadelphia.

Ryan just returned from APFED's 24th Annual EOS Connection Patient Education Conference. It was a wonderful time. Listeners can still check out the resources on demand online.   [1:26] Ryan mentions that a handful of people came up to him at the conference to say how much they appreciate the Real Talk podcast. It was wonderful to hear how impactful the podcast has been for them.   [1:53] Holly introduces today's topic: how parents and caregivers can help children and teens with eosinophilic disorders build the skills and confidence they need to manage their health as they grow and navigate transitions from pediatric to adult care teams.   [2:06] Holly introduces and welcomes today's guest, Dr. Timothy Buckey, an allergist and immunologist at the University of Pennsylvania and the Children's Hospital of Philadelphia.   [2:14] Dr. Buckey's research interests include eosinophilic esophagitis, food allergy, medical ethics, and improving access to medical care for vulnerable populations.   [2:24] Dr. Buckey thanks Ryan and Holly for having him on the program. He's a long-time listener and is looking forward to the conversation on this important topic.   [2:32] Holly comments on Dr. Buckey working with children and adults. Dr. Buckey says he sees patients of all ages, from a few days old at the Children's Hospital through the end of life at the adult hospital. He loves that there's no patient he cannot see.   [3:10] Dr. Buckey says, in addition to seeing patients as an allergist/immunologist, he is also a medical ethicist or bioethicist. He is trained in medical ethics, and he utilizes that approach in shared decision-making, trying to understand his patients' goals and values for their health, and making a plan that works for them.   [3:31] Holly says her allergist/immunologist at Massachusetts General also sees teens and adults.    [3:53] Dr. Buckey says a special aspect of the relationship he has with his patients is that he has been in a fairly similar position, as someone who has dealt with many different allergic or atopic conditions for his whole life.   [4:08] Dr. Buckey says his conditions started with asthma as a young child, which he still manages, allergic rhinitis, and environmental allergies. He has been on allergy shots. He deals with atopic dermatitis, or eczema. He has seen an allergist/immunologist his whole life. It feels like full circle to be one now.   [4:29] Ryan feels like it's easier from a patient perspective if your physician gets it and can understand what you're going through.   [4:41] Ryan says that eosinophilic disorders generally require lifelong management, especially when diagnosed in children. Over time, a patient may need to transition from being treated by a pediatric care team to an adult care team.   [4:57] Ryan says that Dr. Buckey, through his work with the University of Pennsylvania, provides a lot of support for young adults going through that transition. Ryan asks Dr. Buckey to explain the importance of transition of care.   [5:14] Dr. Buckey breaks down the term into its two words: transition and care.   [5:24] Transition of care is a process in which we are shifting from a pediatric health model, in which a parent or guardian is the primary historian, or person managing the patient's care, to one in which the patient becomes the primary point of contact.   [5:49] Dr. Buckey says that during this process, our overarching goal is for an individual to begin to develop ownership of their health so that they can take care of their medications, schedule appointments, and know their bodies.   [6:05] Dr. Buckey says the second part is care. Not only medical care, but it is a period of life of going through a lot of personal growth. Dr. Buckey's goal is for patients to know themselves and learn to support themselves as independent individuals.   [6:30] Holly appreciates that Dr. Buckey talked about the transition at that age when there are so many things going on with becoming an adult.   [6:40] Holly says when she worked at the Children's Hospital of Colorado, we thought about this a lot.   [7:00] Holly said that when she interacted with patients, she tried to look at them, even if they were little. If they were three or four, she asked them what their favorite foods were.   [7:17] Holly says she was trying, as young as possible, to have them feel that they have some say and control over their health, and they can start developing how to be a historian of their medical journey.   [7:36] Dr. Buckey says every person matures or develops at different times. Having a strict age cutoff may ignore the unique aspects of each person and their history. Dr. Buckey generally begins that conversation in the teenage years through the early 20s.   [8:02] Dr. Buckey says that with some kids, he will introduce the idea earlier than a teenager, based on how much they understand about their health. As they start to switch to adult care, he emphasizes that the transition process is not over at their first adult visit.   [8:24] Dr. Buckey says it takes additional visits for that person to understand themselves, to know how to request a refill of their medication, to know how to make the appointment, and to know how to contact Dr. Buckey if they have questions.    [8:38] Dr. Buckey says it is a continual process, and it doesn't just stop at that first visit with an adult doctor.   [8:45] Holly agrees that people reach maturity at different ages. Holly remembers that when she was in college, she asked her mom to schedule her dentist and doctor appointments.    [9:17] Dr. Buckey says it's overwhelming and it can be quite scary. It takes a team.   [9:30] Holly notes there are age ranges on the Healthcare Transition Timeline Toolkit for what the provider should be doing to help the patient get ready for transition, and what the caregiver and the patient should be doing. She invites listeners to check it out at eoscare.apfed.org.   [9:45] Holly asks about ages when a child would meet alone with their physician for part of the appointment to talk about things they don't want to say in front of their parent.   [10:18] Dr. Buckey says it depends on age and individual factors. He says he has met some very mature 10-year-olds and some not-as-mature 17-year-olds.   [10:38] Dr. Buckey says he understands how it might be nerve-wracking for parents to ask them to step out, but it is an important part of that person starting to know their own body.   [10:50] Dr. Buckey says if he's seeing an individual with asthma, he will have the parents step out briefly from the clinic room so he can have a conversation about possible triggers they may not be comfortable talking to their parents about, such as vaping or cigarette use, and if they have tried them or friends have tried them.   [11:20] Dr. Buckey says they will discuss that, and that's not something they always feel comfortable sharing with their parents because they feel like they may be disappointing them. The doctor needs to know it to keep them healthy.   [11:44] Holly says in her practice, a lot of teenagers will ask to meet with her if they have IgE-mediated food allergies on top of eosinophilic-related disease.   [11:51] They want to know if it's safe to kiss a person if they've eaten this or what to do to protect themselves. If they get this symptom, what should they do? They feel comfortable asking Holly. She's trying to coach them to feel confident in their bodies.   [12:22] Ryan comments that he's gone through the transition of care process relatively recently. The conversation has touched on so many things he remembers from the last 10 years of trying to transition.   [12:28] Even before that, at eight or nine, when the doctor asked what medications Ryan was on, his mother looked at him and said, You should know this; you take them every day. What medications are you on?   [12:43] Ryan says that was super helpful to him, as a young patient, that his parents supported him in making sure he was aware of his health, his treatment options, and was able to guide his own medical appointments, with supervision.   [12:57] Ryan had had no idea that he was choking on food or taking extra time to chew. It felt normal, so it was helpful to have a caregiver in the office. His caregiver would say it takes him half an hour to have a handful of crackers. That should not be happening.   [13:20] Ryan asked about caregivers helping with appointment management and prescription management. Until recently, Ryan's parents helped him.    [13:50] Ryan says, even into your 20s, that transition process is still happening. Ryan asks Dr. Buckey for advice on teens and young adults making their own appointments and dealing with healthcare systems.   [14:04] Dr. Buckey says it's diffic

Ryan introduces co-host Holly Knotowicz.   [1:17] Holly introduces today's topic, research on eosinophilic esophagitis (EoE) and dysphagia.   [1:24] Holly introduces and welcomes today's guest, Dr. Claire Beveridge, a gastroenterologist at the Cleveland Clinic. Dr. Beveridge heads the EoE Adult Clinic and the Transition from Pediatric to Adult EoE Clinic.   [1:36] Holly, a speech pathologist, says she is very excited to dive into the research Dr. Beveridge did with EoE and dysphagia. Holly asks Dr. Beveridge to share some of her background.   [1:48] Dr. Beveridge was recruited to the Cleveland Clinic about five years ago to head the EoE Center. She loves the work they have done there.   [1:57] Dr. Beveridge says it's been nice to center everything on their EoE patients and have multidisciplinary care with speech-language pathologists, allergists, dietitians, pulmonologists, and more. It's been a great experience.   [2:15] Dr. Beveridge says the other thing they are really proud of is having a Transition Clinic. It can be tough for patients to transition from pediatric to adult care.   [2:23] Dr. Beveridge says this is something she was inspired to do when she was finishing her training at the University of Pennsylvania, where they had been doing some of that. It was really important to her when she joined Cleveland Clinic.   [2:34] Dr. Beveridge, with her Co-director, Dr. Sophia Patel, helps patients transition from pediatric to adult care.   [2:41] Holly speaks of the challenge of transitioning from pediatric care at a multidisciplinary clinic to adult care.   [3:08] Dr. Beveridge says you can't do any training at Northwestern without loving the esophagus. She did her residency there, got exposed to esophagology, and got to know Dr. Gonsalves and Dr. Hirano really well.   [3:33] Drs. Gonsalves and Hirano are really big names in EoE. Dr. Beveridge was fascinated by the disease. She loved the patients and wanted to help them and make them feel better. It's a burgeoning field.   [3:48] Dr. Beveridge says that it's only in the last few years that we have had FDA-approved medications for it, and that we have been jerry-rigging asthma medications to treat our patients.   [4:03] Dr. Beveridge says it's really exciting to see the treatment options we can offer.   [4:10] Ryan says it's exciting to see how EoE management has changed.   [4:16] Ryan says we see so many patients who are untreated or poorly treated for years, who have restructuring of their esophagus and present with dysphagia, or have strictures and rings leading to food impactions; the long-term effects of untreated EoE.   [4:34] Ryan says it's exciting that now we do have better treatment options for people, right off the bat.   [4:43] Dr. Beveridge conducted some research on EoE and dysphagia and presented a poster at the 2024 Digestive Diseases Week.   [4:51] The poster was titled, "Esophageal Luminal Diameter is Associated with Dysphagia and Eosinophilic Esophagitis: Implications for Endoscopic Dilation Therapy."   [5:11] Dr. Beveridge says dysphagia means issues with swallowing. It's a feeling of something getting stuck or something slowly moving down. There are also subtle symptoms that can happen.   [5:31] Dr. Beveridge says patients who have had EoE for a long time become accustomed to how they swallow. Things a patient may think are normal, like needing water and taking a sip after each bite, are learned accommodating behaviors.   [5:58] Dr. Beveridge says accommodating behaviors are that you're needing to imbibe extra water, you're modifying how you're eating, extra chewing, avoiding pills, avoiding other certain foods, and things like that that can be modifying factors.   [6:19] So, difficulty with swallowing, things getting stuck, slowly moving down, but also keeping in mind some of those modifying behaviors that we may end up using.   [7:23] Dr. Beveridge says her motivation was seeing patients in her clinic who were having persistent symptoms, and getting them into histological remission. The goal of treating your EoE is to get the eosinophils less than 15; close to zero is great.   [7:45] Dr. Beveridge says we have patients who, despite doing their endoscopies and taking biopsies, things look fine; they're still having issues with swallowing. Why is that the case?   [7:58] Dr. Beveridge says in a different research paper she had done, looking at some of the predictors for that, one of them was fibrostenosis. There are also other things that can contribute, like esophageal hypervigilance and a fear of swallowing.   [8:21] If a patient has had a food impaction, it's going to be scary to try to swallow again. Some of it is behavioral, but some of it is structural. At what luminal diameter (the size of the esophagus) is that causing a clinical problem for patients?   [8:45] A normal esophagus is 20 to 24 mm in diameter. Traditionally, around 14 to 16 mm in diameter has been when we say that patients get symptoms or they're feeling the issues with swallowing.   [9:03] Dr. Beveridge says a lot of those studies have never been done specifically for EoE patients.   [9:08] Dr. Beveridge wanted to know, if we exclude cancer, if we exclude acid reflux, and all of these other things, and just look at our EoE patients, what size of the esophagus are we looking at?   [9:20] Dr. Beveridge explained they specifically looked at patients whose histology was under control and then compared those who continued to experience symptoms with those who did not. The goal was to determine the histologic threshold at which patients begin to experience dysphagia.    [9:54] Dr. Beveridge says they saw this threshold at 16 mm (1.6 cm). That's still quite the difference from a normal esophagus of 20 to 24.   [10:08] Dr. Beveridge says our esophagus can definitely handle being smaller, but then, once you get to that 16 mm, for a lot of patients, it really does cause that feeling of things getting stuck or slowly moving down.   [10:20] Holly says what's cool about the retrospective data Dr. Beveridge looked at, and the parameters she placed in the research, is that when a patient goes in for an endoscopy, the doctor can measure and say maybe this is why dysphagia is going on.   [10:48] Holly finds that adult patients with food impactions are scared to eat the same food again. She loves having this data to share with patients and say, let's look at what your esophagus measures at. Let's do a smaller bite. Let's add a dip and liquid.   [11:12] Holly says data can push so much progress. Holly, having multiple chronic illnesses, loves when doctors can say, this is going to be safe. This is the mode that we're going to go with.   [11:30] Dr. Beveridge says in the retrospective study, they were looking at stuff that had already been done. We decided from here to assess patients more prospectively. All of this was based on chart review from when the note said symptoms or no symptoms.   [11:53] Dr. Beveridge says when she started this EoE clinic at the Cleveland Clinic, part of it was to standardize better how we were collecting data from patients to understand their symptoms.   [12:07] Dr. Beveridge has a standardized questionnaire for patients to understand if they are having heartburn and difficulty with swallowing, so she can know that at each point of their endoscopy.   [12:18] Dr. Beveridge says it will be nice, hopefully in the future, when she can give a little more detail and depth in terms of assessing this more prospectively and seeing if that same number holds up or if she needs to tweak it a little bit.   [12:34] Holly thinks it's fascinating. Numbers give us so much information, to know if my mm is this versus this, the next time, or during allergy season or not.   [12:53] Ryan says it's cool that you're able to look back at existing patient records and identify this information. Now we have that 16 mm number in mind to say maybe this is where we'll start to see increased risk of dysphagia in these patients.   [13:28] Dr. Beveridge says, how we had to do it retrospectively was based on the endoscopist estimating what the size is. Gastroenterologists recognize they're not always the best at estimating the size of the esophagus.   [13:50] Dr. Beveridge says, if your endoscope could not pass through, or it was snugly passing through, you know the diameter of the endoscope. If a dilation was done, at what size dilation do we start to see a disruption?   [14:19] Dr. Beveridge says, the goal of a dilation is to get a disruption because there's scar tissue we want to break open. A patient might think disruption means a perforation or something more scary, but that is the goal. We want to break open that scar tissue.   [14:42] Dr. Beveridge says, once we see that scar tissue break open a little bit, then we can estimate what the diameter is, based on the size dilator we used.   [15:10] Dr. Beveridge says for adults, we use a standard adult upper endoscope, and that's about 13 m

Ryan Piansky, a patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, interviews Maddie, a young adult living with EoE, about her journey with EoE and navigating an elimination diet.

Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:51] Host Ryan Piansky introduces this episode, brought to you thanks to the support of Education Partners GSK, Sanofi, Regeneron, and Takeda.   [1:07] Ryan introduces today's topic, eosinophilic esophagitis (EoE). EoE is a chronic, allergic, inflammatory disease of the esophagus. It occurs when eosinophils, a type of white blood cell, accumulate in the esophagus in elevated numbers, causing inflammation that can make eating or swallowing difficult or uncomfortable.   [1:25] Ryan introduces and welcomes today's guest, Maddie, also known as Eosinophilic Chick on Instagram. She's a patient advocate living with EoE.   [1:38] Maddie was diagnosed with EoE in 2021. She has been symptomatic for 10 to 12 years, but was not familiar with the condition itself until then. In her childhood, she was afraid of the upper endoscopy procedure, so she avoided it as much as she could.   [2:06] Besides the patient advocacy that she does, Maddie is an actuary. Throughout the week, she dedicates time to the healthcare industry space in the Philadelphia area. Maddie is 26, navigating her 20s with EoE.   [2:24] Ryan says he feels like being diagnosed as a young adult can be a very big shift. You're going through a lot of other changes: graduating from college, having to figure out work, and having to start managing a chronic illness like EoE.   [2:46] When Maddie was 12 years old, she would have a blockage in her throat. Typically, she walked away from the dinner table and had to regurgitate the food she had consumed.   [3:02] Since heading into college and becoming aware, with the pandemic, of the symptoms of COVID, shortness of breath is one that she leaned into. When she was 21, she felt like she couldn't breathe. It turned out that she was choking on food.     [3:18] There was an impaction, which Maddie obsessed about over time. In addition, around the time she was 21, her symptoms got the best of her. She wasn't able to keep up with thriving, day to day.   [3:31] As a child, some of her symptoms weren't normal, but they were manageable to adapt to: throwing up after a meal, here and there. Her symptoms started to pick up, and she started to lose a lot of weight in her 20s. That's when she sought a diagnosis.   [4:18] Maddie thought it was related to her lung function. She started to lean toward getting diagnosed with asthma, but after testing, that wasn't clear. Her gynecologist thought it was more of a hormonal conflict. They did a lot of labs but got no diagnosis.   [4:45] Meanwhile, Maddie was getting sick. As a last resort, she headed over to gastro. They didn't find anything initially. They did a barium swallow test, another lung function test, and finally, an upper endoscopy.   [5:04] Maddie had spent most of the summer before her senior year of college just trying to figure out what was going on, doing a multitude of tests, and that upper endoscopy with a biopsy captured the EoE.   [5:17] Maddie was able to get support from a specialist who dedicates all of their day-to-day work to EoE treatments.   [5:25] Ryan says it can be tricky to figure out right away what's going on; there are so many other conditions that could be the answer. Until you get to that final diagnosis, it can be a very long process. He's glad she got an answer, eventually.   [5:53] Maddie says, given the timeline of her life, a lot of people were anxious and worried about her future.    [6:08] Once she was able to get that answer, Maddie noticed a lot of relief from a ton of her symptoms, once she was able to get to work on it. Maddie also had an ulcer from frequent vomiting.   [6:25] Maddie had to slow everything down and be very intentional about the things she ate.   [6:51] Maddie lost 15 pounds that summer, as she was trying to gain weight. Whatever she ate, she still lost weight. She was worrying about that rather than about graduating that year.   [7:08] Maddie wanted to know how to register as a disabled student at her university to make sure she got all the resources she needed to be successful.   [7:18] Maddie was rewiring the things she once was worried about, relative now, to what this condition has packaged with it. It was a difficult time. It taught her a lot about discipline, making sure that hard things don't turn her away from achieving the goal.   [7:46] It taught Maddie about being intentional with her time and energy, what's best for her, what's going to make her succeed with whatever goal she's achieving.   [8:07] Ryan says now that Maddie is properly diagnosed, he hopes she's a little bit more in control of her health. Maddie says, "Answers are the biggest power with this condition."   [8:30] Maddie says that before her condition was managed, she went to the ER three times. The first time she was hospitalized, she could not keep down food for two days, so she had to get IV treatment. It wasn't necessarily an impaction, but she wasn't able to eat.   [9:04] The second and third times Maddie went to the ER were related to throwing up again.    [9:26] Maddie's goal was to stop vomiting altogether. She started to get serious with diet therapy, leaning into her six-food elimination diet.   [9:39] Maddie started the diet the week after she graduated, just to be home and have a lot of variables controlled to try the diet, rather than cutting corners. It was really simple to do at home.   [10:04] Maddie first tried cutting dairy, eggs, and shellfish. Her sister is allergic to those foods and is anaphylactic; Maddie is not. That elimination diet was helpful, but it didn't check all the boxes where all her symptoms were free.   [1024] Maddie tried swallowing medication from an inhaler instead of inhaling it into her lungs, trying to coat her esophagus with it. It was effective in the biopsy results, but she was still getting sick, so she did not feel comfortable proceeding with that treatment.   [10:42] All roads led to the six-food elimination diet that could reveal what the culprits were and what was causing her to be so sick. The results were surprising.   [11:06] Soy was a big trigger that surprised Maddie. She consumed so many soy products. That was quite humbling to hear. That was one of her biggest triggers.   [11:34] Maddie completed the six-food elimination diet with triggers of soy, eggs, dairy, nuts, and shellfish. Because of all those groups, it was really difficult for her to manage her diet effectively when going out to eat.   [11:52] Sometimes soybean oil is in a salad dressing or how foods are fried, to a point where Maddie wasn't able to maintain her EoE count below 15 eosinophils per high-powered field.   [12:08] With that, she started with a biologic, dupilumab. That enables her to eat all her trigger foods. An injectable is tough for Maddie as she's not fond of needles.    [12:36] Now Maddie can eat all of the food groups, which is definitely a huge win in terms of her treatment plan. It lessens the impact of living every day with EoE.    [12:53] Ryan says he is on dupilumab, as well. It works well for him. Maddie says she is not avoiding any food triggers, and that's the best part.   [13:24] Ryan says it takes a huge mental load off when you're not having to think about whether there may be soy in what you order from a restaurant, or having to check all the ingredients at the store to make sure that you're not accidentally being exposed.   [13:53] Maddie says, the best advice I would give [to someone on an elimination diet] is focusing on the perimeter of the grocery store. A lot of those foods are dedicated to being whole foods. So, I found that approach to be the most successful.   [14:12] Maddie says, and still finding things that you love and can find new things to enjoy. You're entitled to absolutely enjoy food. It brings a lot of joy into my life.   [14:23] Maddie says, I would specifically love traveling to a bunch of different grocery stores and exploring the allergy aisle. Everyone had their unique niche for it. So, you'll definitely find ones that are more favorable to your preferences than others.   [14:37] Maddie says, but find things, too, that you still enjoy beyond just feeling fully nutritious, and strong, and equipped. You're entitled to indulge, too, even with all the restrictions that you have.   [15:00] Ryan agrees there are a lot of options out there. Exploring and finding something can be really impactful from a quality-of-life perspective, just to have something new. Sticking to the border of the grocery store is a good way of putting it.   [15:13] Ryan says it's everything in those center aisles that gets so complicated. There are always some good, whole food options on the edges, which is nice.   [15:23] Maddie says read every food label, even if you think that you know what's in the food products. A brand of hummus had soybean oil in it. I had to retest, and it added six additional weeks onto my game plan because of that silly mistake.   [15:40] Read everything, even if you think you know it. Odds are, you don't. Don't trust any label until you've fully read it and are confident.   [15:56] Ryan says one of his trigger foods is rice and it does pop up in weird places. Once he was eating potato chips, but then he looked at the

Ryan introduces co-host Holly Knotowicz.   [1:12] Holly introduces today's topic. It's May, and each year in May, there are several awareness observances for eosinophilic-associated diseases, including National Eosinophil Awareness Week, World Eosinophilic Diseases Day, and World EoE Day.   [1:29] Throughout May, APFED is sharing stories from individuals and families living with eosinophil-associated diseases to highlight the impact of these chronic conditions.   [1:38] Ryan says, Today, we'll be discussing eosinophilic esophagitis (EoE). EoE is a chronic allergic inflammatory disease of the esophagus. It occurs when eosinophils, a type of white blood cell, accumulate in the esophagus in elevated numbers, causing inflammation that can make eating or swallowing difficult or uncomfortable.   [1:56] Holly introduces today's guest, Dr. Phillip Arceneaux, a patient advocate living with EoE since 2019.   [2:18] Phil is 35. He was born and raised in Lafayette, Louisiana. He received his undergraduate degree there. He worked at the U.S. Naval Academy in Annapolis, Maryland. Then he worked at the University of Oregon.   [2:38] Phil moved to Florida and did his Ph.D. in Mass Communication at the University of Florida. Since 2020, he has been based out of the Cincinnati area, working at Miami University of Ohio.   [3:05] Phil was diagnosed with EoE in March of 2019, while finishing his degree at UF.   [3:12] Phil was eating dinner with his girlfriend. He took a bite of a roast beef sandwich, and it didn't go down smoothly, it became impacted.    [3:56] Phil thought he had food stuck in his windpipe. He was running around banging his chest. He calmed down and was able to get some of the food out, and he was breathing again.   [4:12] Phil thought he was fine. He quickly realized he wasn't. He still had a partial impaction. He didn't know what was going on in his chest. He spent about 30 minutes moving around, coughing, and trying to get his chest to feel right.   [4:44] After about an hour, Phil decided to go to the ER. His girlfriend insisted on driving him to the hospital. It was spring break, so the ER was not busy. It still took a couple of hours to be seen and treated.   [5:25] The doctors assessed him. They gave him medicine to induce vomiting. About 12 hours after the initial choking, his impaction cleared. They kept him overnight and gave him an endoscopy in the morning to check his esophagus and take biopsies.   [6:31] Phil was in the ER for four to six hours before anyone told him what they thought he had. Then the ER doctor told him he was 95% certain Phil had eosinophilic esophagitis. Phil had never heard of it.   [7:04] The ER doctor gave Phil a rundown of EoE. He said Phil would have an endoscopy, and then he would be referred to a GI and set up for treatment. The doctor said he couldn't confirm it before the endoscopy, but he thought it was EoE.   [7:31] Ryan says he's talked to people who have had months-long processes of getting their diagnosis. Phil gives all the credit to the hospital. He was fortunate that his experience was good.   [7:55] Phil says that the staff at the ER and the GI specialist were so knowledgeable about the research and where things were going in this area of medicine. They were very confident about the diagnosis and treatment plan.   [8:11] Dr. Arcenaux gives a shout-out to his GI. He spent well over an hour with him during his initial consult. He explained how EoE would impact him, from diet, grocery shopping, and challenges eating at restaurants, because of cross-contamination.   [8:42] The GI specialist talked him through impacts on dating and dining out  and how to approach social activities.   [9:09] Phil's GI specialist talked to him about employers. He would need employers with health insurance that will cover the endoscopies and treatments for EoE. Phil appreciated the initial onboarding for his EoE diagnosis.   [9:41] Ryan says he needs to discuss this with Phil, as he just finished his Ph.D. a few months ago, and he's looking at insurance for his new job, and how to figure out business lunches.   [9:51] Ryan says Ph.D. students are so motivated by free food. As someone with EoE, that never applied to him. Ryan says shifting from normal eating habits to an EoE diet is a major shift.   [10:27] Phil knows now that there were signs and symptoms, but he had no idea about them before his diagnosis.   [10:33] Phil is on a special diet for his EoE. When he's not great at avoiding his trigger foods, he starts to see dysphagia symptoms in his swallowing, and he has quite a bit of regurgitation. He had been seeing that for months before this initial major food impaction and ER visit.   [10:54] Phil had no idea what was going on. He just thought it was weird that he was regurgitating more than he used to. Sometimes food didn't go down well. Once or twice, he had a small aspiration event. He thought he needed to chew better.   [11:11] He didn't know what those symptoms meant, and he wrote them off. None of it made sense until that diagnosis. Even then, it took a while to wrap his head around it. Years removed, he sees there were so many signs and symptoms he never processed.   [11:28] Holly asks what Phil means by aspiration. He says he means water going down his windpipe, making it hard to breathe, with liquid in his lungs. Holly says that aspiration can be caused by inflammation in people who have EoE.   [12:07] Holly says people with EoE can be sent for a swallow study to look at the anatomy of their swallow function. That's a subject for another episode!   [12:35] Ryan says Phil noticed he was regurgitating more than normal and remarks that people with chronic illnesses don't realize that most people don't normally regurgitate at all. It's a sign that something's wrong.   [13:03] The ER doctor didn't offer Phil any other diagnosis than EoE. The doctor was 95% sure he had EoE, but confirmed it with an endoscopy.   [13:20] Holly asks Phil what food allergies he has. As an infant, he had an egg allergy that limited his vaccines. Now he knows his primary allergen is egg, and it led to his EoE issues.   [13:51] When Phil started his Ph.D. program, he wanted to eat healthier foods. He cut out fast food, and he ate more eggs. He consumed many eggs during his Ph.D. program. A snack was scrambled eggs or something with scrambled eggs.   [14:22] Phil went through a carton of 18 eggs in less than a week. He knew that when he was younger, he'd had egg sensitivity, but as an adult, he'd eaten eggs and nothing happened that registered as an issue. He thought he had outgrown it.   [14:40] Phil says he had outgrown other food allergies. He assumed eggs were fine, so he adopted a heavy egg diet to increase his protein intake and be healthier. Then all these symptoms manifested.   [15:00] Phil never associated the symptoms with eggs. His treatment plan is dieting and minimizing egg as much as possible. That is not easy in the United States, where everything is processed and often contains egg.   [15:19] Holly says she has seen an influx of adult-onset EoE patients with a history of a dairy or egg allergy who were putting cottage cheese and eggs in everything, and all of a sudden, started having regurgitation and food getting stuck.   [15:51] Phil doesn't eat scrambled eggs anymore. One slice of a cake with eggs in it will not send him to the ER. It takes a couple of days of high exposure to reach that point. He knows what he can have daily that will not impact him in the long term.   [16:20] Holly and Ryan agree that it's important to know your limits, and consult with your physicians about foods. Rice is a trigger for Ryan, but if brown rice syrup is about the 20th ingredient, he can have it and be fine. If he were to eat a lot of rice, he will have issues. [17:21] Phil says he recently got married, and his wife is a health nut. She has radically changed his diet. They eat very high-protein, low-fat, and low-carb. It's been easy to manage that without eggs. They eat a lot of chicken, turkey, and fish.   [17:41] Being from Louisiana, Phil says if he had to give up seafood, he doesn't know what he would do. He's a huge craft beer lover. If he had to give up gluten, he doesn't know what he would do. He can manage without eggs.   [18:21] Ryan says dairy was a big trigger for him when he was younger, but now he's on dupilumab, a biologic approved for treating EoE, and that's helped him a lot. He's started to integrate whey protein and milk protein back into his diet.   [18:47] Phil says once he finished with school, he graduated and lost health insurance. He didn't have a source of income or health insurance, so he declined to have dilation therapy. That's also why he deferred to dietary therapy. He removed his allergens one by one.   [19:12] Phil was diagnosed in 2019, not long before the pandemic hit. He lived in a bubble for two to three years and kept to a very regimented

Co-hosts Ryan Piansky, a graduate student and patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Science Advisory Council, interview Dr. Chukwuemeka Oko, MD, MBA, on clinical trials.

Opinions, information, and recommendations shared in this podcast are not a substitute for medical advice. Decisions related to medical care should be made with your healthcare provider. Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:49] Co-host Ryan Piansky introduces this episode, brought to you thanks to the support of Education Partners GSK, Sanofi, Regeneron, and Takeda. Ryan introduces co-host Holly Knotowicz.   [1:13] Holly introduces today's topic — clinical trials — and today's guest, Dr. Chukwuemeka Oko, a Clinical Research and Medical Affairs Professional supporting Duke University Hospital's Department of Gastroenterology and Transplant Hepatology.   [1:33] Dr. Oko explains that he is sharing general, educational information from his perspective and experience, not speaking on behalf of Duke University, nor any industry sponsor, nor any company he has worked for.   [1:50] Dr. Oko's goal today is to help the listeners feel clearer, more confident, and more in control when they are thinking about clinical research.   [2:29] Dr. Oko's work sits mainly at the intersection of clinical research and medical affairs. He helps translate evolving science into practical, patient-centered decisions.   [2:40] From an academic standpoint, he supports clinical trials and evidence generation from feasibility through education.   [2:49] Dr. Oko also engages investigators and thought leaders from industry sponsors in scientific exchanges that lead to insights, study design, and real-world care pathways.   [3:03] Dr. Oko had two reasons to study eosinophilic esophagitis and eosinophilic disease. The first is the patient journey and biology.   [3:11] On the patient side, many people spend a long time seeking answers. Sometimes they feel dismissed before they get a clear diagnosis and a plan that fits their life.   [3:24] On the biology side, eosinophilic disease teaches us a lot about how our immune signals can drive information differently across tissues like the esophagus and airways.   [3:40] Dr. Oko supported an EoE study experience with an industry sponsor in the past. The best research doesn't just test; it helps patients and clinicians make clearer decisions.   [4:12] Dr. Oko explains that a clinical trial is a carefully designed, carefully crafted study in people that answers specific medical questions, most often about safety, effectiveness, or dosing of the study drug or how a treatment should be used.   [4:32] A key structure of a study is a written protocol where safety monitoring is in place, and the defined outcome or results are very reliable. The FDA always oversees clinical trials in the U.S.    [4:44] Dr. Oko often describes a trial as a highly-monitored learning system. It's how medicine moves from "We think this might help" to "We know what helps, for whom, and also at what risk."   [5:09] Dr. Oko says clinical trials usually study what improves patient outcomes, for whom, and at what risk, using methods that we can trust. Trials may evaluate new medicines, devices, dosage strategies, or even procedures.   [5:31] Clinical trials can also study non-drug approaches such as diet interventions, symptom tracking, monitoring tools, and education strategies.   [5:44] Many trials have also included biomarkers, or signals in the blood or tissue, helping to support an EoE diagnosis so that the patients can get treated in an early and effective manner.   [6:36] Dr. Oko says patients sometimes ask him if they are guinea pigs. In reality, trials are heavily regulated and closely monitored, with strict safety reporting requirements. Participants are not guinea pigs.   [7:06] Dr. Oko also hears patients ask if they are "stuck" once they join the clinical trial. No, a trial is a completely voluntary participation, and they can withdraw at any time.   [7:25] Other patients ask if trials are only for people who are out of options. Many trials are designed for earlier stages, especially when the goal is to prevent complications or reduce steroid exposure.   [7:46] The last question Dr. Oko hears a lot is "Will I be in the placebo group?" He says it's an understandable fear. They are asking if they will go untreated in the placebo group.   [8:29] In many trials, a placebo is not the same as "no care". Often, the participants continue the standard-of-care treatment, and the study drug or placebo is added to the standard-of-care treatment.   [8:45] Trials typically involve symptom monitoring and a plan for what happens if the symptoms worsen. There are exit criteria.   [9:01] From the pharmaceutical side, it's the end of treatment once you decide to voluntarily exit the study.   [9:10] Dr. Oko's advice is, if you participate, ask the study team physicians to explain in plain language what you'll receive, what you can continue, and what happens if you flare up. Clear answers are always a part of ethical research.   [10:33] Holly asks what it means to participate in a Phase 1, Phase 2, or Phase 3 trial. Dr. Oko says a Phase 1 trial is focused mostly on the safety and the dosing regimen. It's usually a small group of five to 100 or so.   [10:52] A Phase 2 trial always looks for the drug's effectiveness and continues monitoring safety. It's usually a group of 100 to 300 subjects. They look for meaningful signals of the outcomes derived from the trial.   [11:10] A Phase 3 trial is usually large. It's multi-centered. It's called a complementary study. It involves thousands of patients. It can even be across nations and states.   [11:26] This is where they compare new interventions against a placebo or against a standard of treatment to provide clinical benefits and support for regulatory approval.    [12:03] Participating in any phase of a trial includes fitting the eligibility criteria of inclusion for that particular phase. If you are a good match, you can be in either a Phase 1, Phase 2, or Phase 3 trial.   [12:52] Holly says she knows that a lot of people with EoE or EGIDs are very curious about trials and how to participate in them.   [13:00] Ryan says we have a very active patient community, and everyone's looking for ways to get involved in research and new diagnostics or medications to improve their own outcomes and help everyone else.   [13:35] Dr. Oko says the benefits of participating in a clinical trial include access to potentially disease-modifying therapies years before they reach the market.   [13:47] Another benefit is extraordinarily close medical monitoring. When you're in a clinical trial, you have more frequent visits and more frequent labs than usual.   [14:01] Endoscopies are out of the normal standard of care, but will be more frequent than normal to analyze the efficacy of the study drug.   [14:11] Dr. Oko says one of the risks is the unknown side effects the study drug comes with, because we are still understanding the biology.   [14:21] The time commitment for visits can be more than typical for a patient, especially if there is a long travel time involved. Patients may arrive at 7:00 or 8:00 a.m. They may need to find a place to live nearby, depending on the pace of the trial.   [14:57] Holly lives in Maine, and a lot of the trials are in Boston. It's a lot of travel. For people with any kind of chronic illness, all we think about is money. Holly asks if people pay to be part of a clinical trial.   [15:25] Dr. Oko states that the patients do not have to pay anything to be part of a clinical trial. Patients do get compensated by the trial sponsor for travel, accommodation, parking, and a meal for the days they are onsite.   [16:33] Dr. Oko says that patients tend to bring up insurance. It is a misconception that the study will pay for their standard-of-care medication during the study. Patients need to ask the study team what insurance will pay for and what the study will pay for.   [16:59] Dr. Oko says the insurance usually covers the regular standard-of-treatment, but any other additional treatment, procedures, and visits are all covered by the study sponsor.    [17:29] The study sponsor may ask for an endoscopy to be done six months before the study to determine eligibility for the study. If it is done within a year, the study sponsor will determine if you are qualified. That is part of the eligibility criteria in some cases.   [18:26] Dr. Oko tells patients to always ask questions, like what the schedule of events is in the clinical trial.   [18:35] The schedule of events tells you how many visits are required for you to be part of this study. They will list the activities to be done. They will list the labs you will need at what week. They will list when you need endoscopies, at week one and later.   [19:05] If you exit from the study, if you don't want to participate anymore, you are still required to come on site just to make sure that you are in good shape. Those are called formal visits.   [10:29] Dr. Oko explains that formal visits are necessary for the patient's safety and to make sure that the data points collected in the study will be effective.   [20:01] Patients enrolling in a clinical trial can also ask about the known risks of the symptom monitoring plan. They can ask what is covered and what is not covered by insurance, and what will be considered out of pocket.   [20:20] If patients are in the placebo group, what will happen if sympto

Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:51] Co-host Ryan Piansky introduces this episode, brought to you thanks to the support of Education Partners GSK, Sanofi, Regeneron, and Takeda. Ryan introduces co-host Holly Knotowicz.   [1:13] Holly introduces today's topic — research on social vulnerability and eosinophilic esophagitis (EoE) — and today's guest, Angelica Lackey Mirzoca, a fourth-year medical student at the University of North Carolina School of Medicine in Chapel Hill.   [1:38] Angelica will start an internal medicine residency this summer and is planning to do a fellowship in GI and liver disease. Before medical school, she studied public health nutrition at UNC and worked in clinical research in eosinophilic diseases.   [1:58] Angelica has been able to use her analytic and public health skills as a member of UNC's EoE Research Group, which is part of the larger Center for Esophageal Diseases and Swallowing, led by Dr. Evan Dellon.   [2:15] Ryan sees Dr. Dellon as his GI. Dr. Dellon has been a guest on the Real Talk: Eosinophilic Diseases podcast. Ryan says Dr. Dellon is wonderful, and many in the community look up to him. It's exciting that Angelica is doing research alongside him.   [2:38] Dr. Craig Reed, part of the EoE Group, who works closely with Dr. Dellon, invited Angelica to a research meeting. She's always had an interest in digestive tract function and diseases.   [2:55] When Angelica was growing up, her father had Barrett's Esophagus. She saw him choking a lot when he was swallowing. It was really scary.   [3:04] Angelica says that being in the EoE space and appreciating the impact that problems swallowing have, not only on the patient's everyday life but on the people around the patient, it was important to her to dedicate her skills and time to EoE.   [3:37] Angelica researched EoE and social vulnerability. Her abstract at the 2025 Digestive Diseases Week was titled "Increasing Social Vulnerability Impacts Presentation and Decreases Treatment Response in Eosinophilic Esophagitis."   [3:58] Angelica explains that social vulnerability is a term to describe the context of people's day-to-day lives and the barriers and obstacles they navigate.   [4:07] In this context, their lived experience has a dramatic impact on people's ability to anticipate and recover from different stressors.   [4:16] Some groups are notably more vulnerable, including kids, older adults, single-parent households, and people who live with physical and mental disabilities.   [4:28] Social vulnerability can be measured qualitatively in terms of socio-economic status and household composition. Other composite scores or variables can serve as quantitative assessments of social vulnerability.   [4:50] Ryan says he does research for graduate school associated with climate vulnerability and infrastructure. He has done some work with the CDC's Social Vulnerability Index and the Climate and Environmental Justice Screening Tool.   [5:20] Angelica says they used the CDC's Social Vulnerability Index in the study. It's a 16-variable composite score with four overarching themes. It's down to the Census Track level. You can associate it with patient zip codes.   [5:37] The SVI can populate into patient charts or a QI database. It was very easy to incorporate into the database.   [5:50] The QI database was developed to help people understand what neighborhoods and communities might need additional support in natural disasters. It includes variables that impact people's health day-to-day.    [6:18] Angelica says health equity is core to everything she does. Participating in the EoE research, it was important to her to consider the social vulnerability, or people's lived reality, and how it impacts their ability to feel empowered to access care.   [6:42] Angelica talks about people not knowing what's wrong with them, choking. Angelica worked in restaurants for 12 years before going to medical school. She listened to a lot of people share their struggles to communicate with the doctors.   [7:09] Holly says when she worked at a major children's hospital in an EoE clinic, they had local patient families and patients that flew in from farther away. The local patients got to see her weekly for feeding therapy. That's when she started doing telehealth.   [8:04] Angelica says the biggest strength of the database is its size. Having 1,400 people and adding every new diagnosis they get at UNC, and every new diagnosis over the past 23 years.   [8:25] There are adult (60%) and child (40%) patients in the database. There is also a good range of social vulnerability among the patients.   [8:42] Ryan notes that one of the findings of this research was that people with higher social vulnerability often experience delays in diagnosis.    [8:52] Angelica says most of the work was postulating on what could be the things that kept people from being diagnosed early, which is important. Angelica hopes that all institutions work to ensure that early endoscopies and biopsies are done.   [9:!2] The new guidelines help. Having that high index of suspicion for everyone, not basing it on demographics or judging by appearance, for whether someone needs biopsies or not.   [9:28] Social vulnerability includes access to care, getting endoscopies and biopsies, having health insurance, and ER care, which is expensive even with insurance. Specialty copays are expensive. Transportation is expensive.   [9:53] Taking time off work can be hard. People take time off to get care for their children, but often not for themselves.   [10:18] Ryan was diagnosed in 2002. Knowledge of EoE was not widespread, but his parents took off work and took him to doctors out of state. They had insurance that covered it. He saw five or six physicians in multiple states before he got a diagnosis.   [10:42] Ryan's situation is not feasible for most people. He says he is fortunate to have gotten to a doctor who had the expertise to diagnose EoE.   [10:51] Ryan says Dr. Emily McGowan was a guest on the Real Talk: Eosinophilic Diseases podcast (Episode 15), speaking on access to specialty care for EoE. She had researched urban and rural populations getting diagnosed with EoE.   [11:05] Her research showed that if you're near a center that can diagnose you, you get diagnosed more frequently, which brings it back to access to care.   [11:19] Angelica's research did not look at the urban/rural divide. That's something that may be a future direction of research. Eighty percent of North Carolina, where the study was located, is rural.   [11:41] The Social Vulnerability Index shows there is the highest vulnerability in more rural areas, especially Eastern North Carolina. Angelica imagines that the urban/rural divide plays a big role.   [11:59] Holly grew up in rural New York. She wasn't diagnosed until her twenties. She had issues, but her parents couldn't take her to be diagnosed. It's reassuring to have someone look into this, because when people do research, things change.   [12:30] Ryan says all of these points make a lot of sense on the diagnostic side. If you are in a more socially vulnerable place, you don't have the resources. You can't go and get that diagnosis.   [12:41] Ryan mentions the study found a difference in symptoms, such as vomiting, nausea, and abdominal pain. Ryan asks what that tells us about how EoE may affect patients differently in these different circumstances.   [12:53] Angelica says the study group was 40% children, and children can present with different symptoms, like belly pain and regurgitation. They're eating different foods and may not be noticing solid foods getting stuck as often.   [13:20] Anglica says there can be a lot of overlap with GERD and EoE. There may be some gut-brain interaction. There's a lot of psycho-social stress among people who have higher social vulnerability. That often manifests with the motility of the GI tract.   [13:56] Angelica says their database doesn't include people who have eosinophilic GI diseases outside of EoE.   [14:13] Holly says the study also showed that patients with higher social vulnerability were less likely to respond to swallowed steroid treatments, even after accounting for factors like age and insurance. Holly asks Angelica to explain this finding.   [14:34] Angelica says this is really important. The way you manage EoE is very patient-specific. The new guidelines give jurisdiction to you, as a patient, and your provider in deciding other things.   [14:51] You can choose dietary therapy first, or topical steroids first. People can take PPIs. They used to be required first, but now they are not. Topical steroids, the ones that you swallow, are common. Cutting out foods from your diet can be challenging.   [15:17] Some people don't love the idea of taking medicine daily in their twenties or thirties.   [15:32] The fact that you would start a patient on something and not see a histologic response opens up the door to follow-up questions of why it is not working.   [15:50] Holly says the pattern wasn't shown in people using diet-based treatments and asks what might explain that differenc

Ryan introduces co-host Holly Knotowicz.   [1:13] Holly introduces today's topic — eosinophilic esophagitis and life transitions — and today's guest, Jessica Grady, a patient advocate living with EoE.   [1:35] Jessica is a mom who was diagnosed with EoE in her 20s, after years of unexplained symptoms: acid reflux, GERD, food impaction, and anxiety around food. For about six years, Jessica searched for answers while dealing with these issues.   [2:00] Since then, Jessica has tried PPIs, steroids, and two clinical trials. She was always interested in the research, so being part of it has been valuable to her. There's a lot of work involved in clinical trials, and it's not easy.   [2:29] Jessica is managing her condition and has hit her second endoscopy with remission, with dupilumab. That's exciting, after her long journey. It has taught her the importance of advocating for yourself and staying hopeful with a chronic condition.   [3:01] After college, Jessica was going out with friends, and had pain almost like ulcers in her stomach. She thought maybe she was going out too much.   [3:20] One day at lunch, water got stuck. Jessica says it was like gargling; it wouldn't go down. Finally, it went down, and she took a bite of food, and that got stuck. That was her first episode. After that, Jessica has had food impactions as her main symptom.   [3:54] Jessica says it's quite a reality check when you're choking on water. How is that even possible? Once that happened, Jessica kicked herself into gear and had an endoscopy.   [4:12] Food impaction is Jessica's number one symptom. She has been to dinners where it happened, and she calmly excused herself from the table until she could finally get the food to go down.   [4:34] As Jessica aged, her food impactions started getting longer. That was terrifying, especially as a Mom needing to take care of her baby.   [4:52] Holly shares how she had symptoms from infancy and all the way through her childhood, and it was diagnosed as anxiety, until she started working in an EoE clinic and recognized her symptoms. Getting an EoE diagnosis is often very challenging.   [5:40] Jessica went to three different hospitals in her area. She didn't know what kind of doctor to look for. She went to a GI, got an endoscopy, and woke up with a fat lip. The doctor told her not to have caffeine and start on PPIs.   [6:11] There was no mention of a biopsy or EoE. She was told she had bad acid reflux and ulcers.   [6:35] The PPIs didn't help. She still had acid reflux and impactions. She was still uncomfortable.   [6:47] Jessica switched to another healthcare system and got closer to the answer, with more endoscopies and testing, but there was no research with it.   [7:02] Finally, Jessica switched to where she is today. There is a doctor and research. They run clinical trials. She gets the latest and greatest updates. She feels like it has helped her get to where she is today.   [7:21] Jessica said the doctor knew what to look for. The moment she described her symptoms, the doctor said it would need to be confirmed with a biopsy, but she has EoE. Jessica asked what now?    [7:34] Ryan says, we hear a lot of difficulty with diagnosis because not all doctors know what to look for. If they see ulcers or other common symptoms that people with EoE have, they can very easily misdiagnose. It's a tricky diagnosis to make.   [8:03] Jessica says that before her EoE diagnosis, doctors told her she had GERD, acid reflux, ulcers, and anxiety around food. They asked what her food choices were and if she was taking too big bites.   [8:12] Jessica asked the doctors why she always needs to have a bottle of water with her, and why she feels panic if there's something like a soft pretzel. They told her she was hyperactive and had anxiety. Jessica felt that that was not making sense.   [8:40] That is why Jessica feels it is so important to advocate. There's a lot of time involved when you're misdiagnosed. You get your hopes up and have lots of highs and lows. It's exhausting.   [8:53] Ryan says that when you do get diagnosed, you can start to treat the underlying condition properly, make progress, feel better, and feel like you're being listened to.   [9:30] Jessica's current course of treatment is PPIs and dupilumab. She's learned her food triggers. Being on the biologic means she doesn't have to worry as much about her triggers, but they can still cause symptoms. She doesn't eat nuts or pineapple.   [10:16] Jessica used to eat cottage cheese if she had acid reflux, but now she knows dairy is one of the worst things to have. She does her best to be mindful. She's really thankful that she's in remission now and can be like everyone else at the dinner table.   [11:04] Holly mentions that there are many trigger foods. It's patient-dependent. Dairy is the number one trigger, but we all have different little triggers, like pineapple. Holly's EoE is triggered by any melon. Ryan's EoE is triggered by apples and rice.   [11:48] Holly avoids all trigger foods for fear of an impaction or throwing up.   [12:27] Jessica says, if she wants to have an ice cream cone and live her life like everyone else, she will, but then she has guilt and wonders if it will do something to her later. She limits the high-allergy foods. If she has ice cream, she won't have cheese.   [13:06] Jessica monitors her food as much as possible. Her GI tells her that, since she's in remission, she doesn't need to be that careful. But she has anxiety because you never know if she will have a problem.   [14:21] Jessica's GI had told her that she was only allergic to a few nuts and she could try other kinds of nuts. She tried cashews once and had a reaction. She reported it to her GI, and then he told her to avoid all nuts.   [14:47] Jessica recently went to her allergist to be retested for common allergies. The tests came back negative for every allergy. She doesn't know if that was because of being on the biologic treatment.   [16:01] Jessica's profession is clinical trial technology. That helped her to understand what a clinical trial is, how to enroll, and patient recruitment. When she went to a hospital with GI research, she asked about it. They had openings, and she enrolled.   [16:33] Jessica was interested in clinical trials because she was desperate for options and answers. Also, the cost of endoscopies adds up. Clinical trials are free. Sometimes you get paid. That was a big win for Jessica.   [17:09] When there was an option for a new treatment, she jumped at it both times. She participated in two trials. She didn't make it through them.   [17:21] In the first trial, Jessica's biopsies had two out of three criteria the trial was looking for, although she had active EoE.   [17:33] In the second trial, Jessica had a provision device she used to write a daily diary entry in. She was pretty far in, but then she had tech issues and emailed for help. That's not part of the protocol. If your diary is not logged correctly, you are out of the trial.   [17:57] That trial was an oral medication. She doesn't know if she was on the placebo or not. Jessica is always open to trials. She thinks they are very beneficial.   [18:46] After leaving the first trial, when Jessica's biopsies didn't meet the criteria, Jessica asked the clinical research nurse to keep her in mind for future trials, so she learned of the second trial.    [19:07] Jessica says she put a lot of time and effort into the second trial, with check-ins and multiple endoscopies, until she was dropped from it. It was challenging and very disappointing when she was dropped from the second trial. She was hopeful.   [19:40] At that point, Jessica changed course and started corticosteroid treatment. The inhaler didn't work. Then she did the slurry mix, and that didn't work, and then she did the injections.   [20:09] Ryan notes that Real Talk has talked to many researchers who have run clinical trials. Every time, they say they are so grateful for the community volunteering their time.   [20:21] They're very aware that some difficulties and challenges come up. Not all patients can make it to the end of the trial, whether that's on the research side or on the patient side.   [20:34] Ryan says the eosinophilic-associated disorder community, in general, is so willing to volunteer their time and participate in these things, and further research for the overall community. Ryan says it's good to hear that Jesica tried to participate.   [21:01] Jessica says she thinks it's valuable. She recommends that anyone who is interested should look into it, especially if you know you have something that's for the rest of your life. What do you have to lose?   [21:12] Jessica says she has something that can't be cured, so what is she going to do? She wants to be the tester. She wants to find something to help her. She doesn't want to choke anymore.   [21:29] Jessica wasn't a mom when she started in these clinical

Co-hosts Ryan Piansky, a graduate student and patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Sciences Advisory Council, interview Beth Morgan, a medical billing advocate and consultant, on navigating your medical bills.

Opinions, information, and recommendations shared in this podcast are not a substitute for medical advice. Decisions related to medical care should be made with your healthcare provider. Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:51] Co-host Ryan Piansky introduces this episode, brought to you thanks to the support of Education Partners GSK, Sanofi, Regeneron, and Takeda. Ryan introduces co-host Holly Knotowicz.   [1:12] Holly introduces today's topic, Medical Billing, and today's guest, Beth Morgan, a medical billing advocate and consultant.   [1:31] Beth says a medical billing consultant is an individual who assists someone with medical bills to make sure that they are accurate and correct, and that they match the medical records, which are notes that the provider makes.   [1:48] The medical billing consultant or advocate can make sure the bills are paid correctly and that the charges are within the reasonable prices for the treatment area.   [2:19] Beth explains how medical insurance covers healthcare costs. It protects the patients and providers from very high expenses. It can also possibly help with the stress of navigating healthcare systems.   [2:36] The goals of medical insurance are to help cover patient costs for treatments, preventive care, and prescriptions. It can also provide resources for telehealth visits or support visits, if needed.   [2:48] With a telehealth visit, you, the patient, have to make sure that your insurance plan covers and allows it. Sometimes, the cost of a telehealth visit can be more than if you were to go to the office.   [3:27] Beth says most people look at what insurance will cost them per month. They fail to look at their yearly deductible, per person or per family, their prescription costs, or what it will cost to see a specialist. They don't consider what therapies will cost them.   [4:08] Beth had a client whose insurance company would only cover in-state providers. If she went out of state, she wouldn't be covered; even an emergency might not be covered. You have to look at the "nitty-gritty" of the policy.   [4:32] Beth says the biggest things are the deductible and copay, or co-insurance. Don't just look at the cost. Most people will take out the $10,000 or $5,000 deductible plans, saying it only costs $75 for the entire family. What does it actually cover?   [5:00] You don't want sudden surprises when you get to the emergency room. You want to know what your copay will be when you go into an emergency room.   [5:11] Holly agrees with Beth and notes that Real Talk listeners have chronic illness. Some have multiple illnesses. When you're selecting insurance plans, those are the things you have to look into.   [5:27] Patients with EoE often need endoscopies and other specialized procedures. Holly asks for tips on how someone can know what an endoscopy or other procedure will potentially cost.   [5:41] Beth says to ask the doctor what the CPT code is. That's the code that describes the treatment. Then look up that CPT code on the insurance company website. They will show an estimated cost for that treatment, for a rough idea of the cost.   [6:10] Keep in mind that it will not tell you what the providers will charge or what the hospital fee will be.   [6:21] Holly says she has EoE and MS. She asks a social worker for the CPT code for every procedure so she has a record to double-check when the bill comes. The CPT code is the key.   [6:50] Holly is a speech pathologist who does feeding therapy. She says to look at your plan to see if therapy is a copay or if it goes toward your deductible. If it goes toward your deductible, it will be very expensive until you meet that deductible.   [7:10] People living with an eosinophilic disorder may find themselves in the ER for a variety of reasons. Holly was there this week with a food impaction. For others, it could be a pain flare or an asthma attack.   [7:26] Holly asks how families can be prepared for medical bills related to emergency care.   [7:40] Beth replies, You also have on that bill the ER doctor and the ambulance fee, including mileage, which must be accurate or rounded up to the next mile. Track the mileage in your car.   [8:43] Who will be transporting you: volunteers from the fire department, a hospital ambulance, or an outside ambulance? Are you going under Basic Life Support or Advanced Life Support?   [9:05] Once you get to the ER, have someone else with you who can advocate for you. Sometimes, staff will bring you forms to sign before they treat you. If you're in a lot of pain, you're not in your right mind to sign those forms; you're only thinking of your pain.   [9:53] Ryan says a friend of his went to his doctor's office for a prescription refill. Typically, he pays a $25.00 copay per visit. This prescription refill visit was not covered in the same way as other visits, and he received a bill for over $200. The insurance company only covers maintenance appointments.   [10:48] Beth says an Explanation of Benefits (EOB) comes from your insurance company. It shows what the doctor charged, what the insurance company paid, and what you owe.   [11:07] A medical bill is what your provider sends you. Beth always asks the provider to send the bill after the insurance company has paid. That way, you know the insurance company has paid on the bill, and there are no surprises.   [11:25] When the provider bills you, the insurance company may have paid something on it, or it may have applied the bill toward your deductible or copay.   [11:44] When a patient receives a provider bill, Beth says they can go to a company called FAIR Health to see today's rates of what should be charged. Insurance companies negotiate rates with providers.   [12:04] Beth says that an out-of-network provider of physical therapy can charge, for example, $160 a visit, and you have to pay out-of-pocket. They can send it to your insurance company, and the insurance company may only pay 30% of the charge.   [12:20] Call the insurance company to ask questions about your insurance. Utilize the estimated costs feature on your insurance company's website.   [12:32] Beth says she always keeps the page of her health insurance booklet that shows what a PCP office visit, or outpatient specialist visit, will cost. Most people get the book and toss it out, but that page is very helpful.   [12:53] If you go into the emergency room, you might have a $300 copay just to be seen, but if you ask them to bill you after they bill your insurance company, most places should respect that.   [13:11] Beth says that most of the time, the red flags that she looks for on medical bills are supply items. Most supply items are included in the cost of the hospital visit. She says a surgical hospital visit is like an oil change.   [13:42] Beth compares a surgery to an oil and filter change. When you go in for surgery, the drape they put over you is included. You only pay for the supply items you walk out with.   [15:15] Beth says, If there's something wrong on your medical bill, your insurance rep may not know the answer. Most insurance companies have outsourced their billing questions. Start with the billing department of the hospital.   [15:35] Ask, "Why did you bill me for an X, Y, Z, when I didn't have an X, Y, Z? I had an A, B, C. Can we re-examine this, please?" Another thing is to go back to your provider.    [15:52] The provider can request medical notes, which are part of your patient record, and you can look at them yourself. Beth says, for hospital stays, she always tells people to ask for a completely itemized bill.   [16:12] Holly agrees.   [16:20] Beth says you have to look at the itemized bill. Does something make sense to you? Does it look a little unreasonable? That's easy to see.   [16:26] Ryan says when you call your insurance company, it can be time-consuming to reach the person who can answer your question, but it's important to do so, especially for expensive things like hospital stays. Doctor's office visits can also be expensive.   [16:58] Something else that can be tricky is medications. Especially for those of us with chronic illnesses and the rare diseases that we work with here at APFED, costs can be quite high for some of the medications patients take.   [17:20] Beth says, When you call the insurance company, ask for the name of the person you are talking to. Write down the name, date, and time that you spoke to the person. Ask them for a call reference number, where they are located, and what was discussed so you have record of that information.   [18:04] For medications, you can look up prices through GoodRx or other prescription websites that might give you an estimate of what the possible cost could be.   [18:20] If your provider states on the prescription, Do not substitute or give generics, you might be paying full price. Otherwise, most pharmacies will offer you the generics.   [18:35] Holly asks, If someone feels overwhelmed by billing or insurance issues, where can they go for help? Are there resources that you recommend?   [18:45] Beth says, There is a patient advocate group, with individuals across all 50 states, that will help you with medical bills and advise you on everything else. Your provider's office or the facility also might have someone who could help you.

Ryan introduces co-host Holly Knotowicz.   [1:14] Holly introduces today's topic, two APFED HOPE on the Horizon Pilot Grant Projects and today's guest, Fei Li Kuang, MD, PhD, an Assistant Professor in the Division of Allergy and Immunology at Northwestern University Feinberg School of Medicine in Chicago, Illinois.   [1:42] Dr. Kuang is a physician-scientist who takes care of patients with eosinophilic disorders and also performs laboratory research on these disorders in her lab, often using patient samples. Holly thanks Dr. Kuang for joining us.   [2:05] As a child, Dr. Kuang always wanted to be a scientist. She is so grateful to live out her childhood dream, and it's because of the amazing people who have supported her, most importantly, her parents.   [2:29] In graduate school, Dr. Kuang studied B cells. When she went on to do an allergy fellowship, she thought she would study B cells and care for patients with B cell problems. Instead, she fell in love with allergy and eosinophilic disorders.   [2:50] Dr. Kuang is here, in part, because of the different mentors she has had, and in large part, because of the patients she has met along the way.   [3:20] Dr. Kuang had the opportunity to work with Amy Klion at the NIH in a clinical trial to treat patients with a drug that gets rid of eosinophils. She says it was a dream come true after her training.   [4:02] She says she learned so much about eosinophils, their unusual biology, and the mystery behind what they are here for. She got hooked.   [4:15] Dr. Kuang thinks the patients you meet in a clinical trial in a special place like NIH occupy a space in your heart that makes you want to keep working on the subject area.   [4:34] Patients in a clinical trial have given up a bunch of their time to travel to Bethesda, Maryland. For the trial Dr. Kuang participated in as a Fellow, it was a good year of their time to come out and do it.   [4:47] Dr. Kuang felt there were so many interesting questions, from an intellectual point of view, but there was also a real need from patients with chronic conditions. It was a beautiful opportunity to marry scientists with physicians in training.   [5:36] Dr. Kuang shares some knowledge about eosinophils. They are white blood cells that are in all of us. They have little pink packages or granules that "jumped out" in the light microscope almost 200 years ago, when we first identified them.   [6:00] Dr. Kuang says that animals, dating back to reptiles, and different species of dolphins, all have eosinophils. A veterinary scientist, Dr. Nicole Stacy of the University of Florida, has taken photos of eosinophils from all these different species.   [6:21] They've been around for a long time. What are they good for? What we know is that they are associated with disease conditions, such as asthma and others, including leukemia. Those were the classic first studies of eosinophils.   [6:42] Now, we have a different mindset about eosinophils from work by the late James Lee at Mayo Clinic, Arizona.   [6:58] Dr. Kuang credits Dr. Lee with suggesting that eosinophils not just cause us problems but also help treat parasitic infections, maintain tissue homeostasis, help wound healing, and tissue repair. That's a new area we are beginning to appreciate.   [7:41] Dr. Kuang says we need to be open-minded that in some circumstances, eosinophils may be helpful or innocent. Now we have tools to start to understand some of that. We need to collect information from patients being treated with medicines.   [8:10] Ryan tells of being diagnosed as a kid. Doctors explained to him that eosinophils fight parasites, but in some people, they get confused and attack the esophagus. That's EoE. That was easy to understand, but he knew that the researchers knew more.   [8:53] Ryan is grateful to the patient population around eosinophilic esophagitis, and is proud of APFED's support of patients and caregivers with HOPE Grants. APFED has the HOPE on the Horizon Research Program, entirely funded by community donations.   [9:13] To date, APFED has directed more than $2 million toward eosinophilic disease research initiatives through various grant programs. As a patient advocacy organization, APFED works with fantastic researchers who submit innovative research ideas.   [9:32] These research ideas go through an extensive and competitive peer-review process, supported by researchers and clinicians in the APFED community.   [9:42] Today, we're going to discuss two different projects supported by HOPE Pilot Grants with Dr. Kuang.   [10:00] Dr. Kuang thinks there are two ways these grant programs are important to patients. One is advancing research by nurturing seedling investigators. Dr. Kuang got her first grant when she was a Fellow. It was an incredible opportunity.   [10:25] These grant programs also nurture seedling ideas that don't have enough evidence yet to garner the larger NIH grants, and so forth. There are other sources for grants: pharmaceutical companies. The grant programs are for seeds.   [10:49] Patients need to know that there are new things that are given some chance of being tested out. Research takes some time, and the FDA process of getting a drug approved is long.   [11:04] For the newly diagnosed patient, it can feel overwhelming. It feels like there's a loss of control. Sometimes, participating in something like APFED, being part of a community, gives back a sense of control that is lost when you're handed a diagnosis.   [11:45] For patients who have had it for a long time, when they participate in research and become engaged in organizations like APFED, they know they may not directly benefit today, they may benefit later, but they hope future patients will benefit.   [12:21] That gives them a sense of control and hope that things will be better for the next generation. We all want that, especially in medicine, in something that we don't have a very deep understanding of.   [12:58] Dr. Kuang received two HOPE Pilot Grants, one in 2018 and one in 2022. The first grant was awarded when she was a Fellow at the NIH.   [13:05] That first grant explored some effects of eosinophilic depletion of pathogenic lymphocytes in hypereosinophilic syndrome and overlaps with EGIDs. Ryan asks for a broad overview of that research.   [13:25] When Dr. Kuang was a Fellow at the NIH, they were doing a Phase 2 clinical trial, looking at "blowing up" eosinophils in patients who have a lot of them, hypereosinophilic syndrome patients.   [13:39] They included patients who had eosinophilic GI disease, often beyond the esophagus. They may have esophageal involvement, but sometimes their stomach is impacted, sometimes their large bowel is impacted, with related symptoms.   [13:57] What Dr. Kuang and the team noticed in the trial was that just within that little group of patients, there were people who did well, and people who did much better than before, but would have recurrent symptoms, and with no eosinophils in their GI tissues.    [14:16] The researchers wanted to know what was causing these problems for the patient. If you take eosinophils away, what other factors will impact the immune system of the patient, semi-long-term?   [14:32] Their focus was on these groups of patients who had different responses. They looked at the white blood cells that had been previously described as being the responsible, "bad" T cells that lead to eosinophils in the gut.   [14:49] They found that the patients who had recurrent flares of the disease had more of the bad T cells, and the patients who responded well and never complained again about symptoms did not.   [15:03] That allowed researchers to identify that there were subsets of patients with the disease that they were calling the same thing.   [15:18] Dr. Kuang says that work also led them to find that those cells were being reported in patients who had food allergies for which they needed an epinephrine auto-injector.   [15:27] The researchers were curious whether that was just a food allergy issue, or only applied if you had food allergies and eosinophilic GI disease. That HOPE project allowed them to do a pilot study to look at food allergy patients, too. They did, and published it.   [15:45] They published that in patients who have a food allergy and have these T cells, the insides of those cells make different messages for the immune system than the ones that the researchers had previously described.   [16:01] In looking for why there were differences in those responses, they accidentally found that there were differences inside these cells in a completely different disease, which also had these T cells.   [16:21] Dr. Kuang says that the finding was kind of a surprise. If they had found anything in the eosinophilic GI disease patients, that would have been good. They also looked at the epithelial cells and the structure of the GI lining.   [16:4

Ryan introduces co-host Holly Knotowicz.   [1:14] Holly introduces today's topic, predictors of not using medication for EoE, and today's guests, Dr. Evan Dellon and Dr. Elizabeth Jensen.   [1:29] Dr. Dellon is an Adjunct Professor of Epidemiology at the University of North Carolina School of Medicine in Chapel Hill. He is also the Director of the UNC Center for Esophageal Diseases and Swallowing.   [1:42] Dr. Dellon's main research interest is in the epidemiology, pathogenesis, diagnosis, treatment, and outcomes of eosinophilic esophagitis (EoE) and eosinophilic GI diseases (EGIDs).   [1:55] Dr. Jensen is a Professor of Epidemiology with a specific expertise in reproductive, perinatal, and pediatric epidemiology. She has appointments at both Wake Forest University School of Medicine and the University of North Carolina at Chapel Hill.   [2:07] Her research primarily focuses on etiologic factors in the development of pediatric immune-mediated chronic diseases, including understanding factors contributing to disparities in health outcomes.   [2:19] Both Dr. Dellon and Dr. Jensen also serve on the Steering Committee for EGID Partners Registry.   [2:24] Ryan thanks Dr. Dellon and Dr. Jensen for joining the podcast today.   [2:29] Dr. Dellon was the first guest on this podcast. It is wonderful to have him back for the 50th episode! Dr. Dellon is one of Ryan's GI specialists. Ryan recently went to North Carolina to get a scope with him.   [3:03] Dr. Dellon is an adult gastroenterologist at the University of North Carolina at Chapel Hill. He directs the Center for Esophageal Diseases and Swallowing. Clinically and research-wise, he is focused on EoE and other eosinophilic GI diseases.   [3:19] His research interests span the entire field, from epidemiology, diagnosis, biomarkers, risk factors, outcomes, and a lot of work, more recently, on treatments.   [3:33] Dr. Jensen has been on the podcast before, on Episode 27. Holly invites Dr. Jensen to tell the listeners more about herself and her work with eosinophilic diseases.   [3:46] Dr. Jensen has been working on eosinophilic gastrointestinal diseases for about 15 years. She started some of the early work around understanding possible risk factors for the development of disease.   [4:04] She has gone on to support lots of other research projects, including some with Dr. Dellon, where they're looking at gene-environment interactions in relation to developing EoE.   [4:15] She is also looking at reproductive factors as they relate to EoE, disparities in diagnosis, and more. It's been an exciting research trajectory, starting with what we knew very little about and building to an increasing understanding of why EoE develops.   [5:00] Dr. Dellon explains that EoE stands for eosinophilic esophagitis, a chronic allergic condition of the esophagus.   [5:08] You can think of EoE as asthma of the esophagus or eczema of the esophagus, although in general, people don't grow out of EoE, like they might grow out of eczema or asthma. When people have EoE, it is a long-term condition.   [5:24] Eosinophils are a type of white blood cell, specializing in allergy responses. Normally, they are not in the esophagus. When we see them there, we worry about an allergic process. When that happens, that's EoE.   [5:40] Over time, the inflammation seen in EoE and other allergic cell activity causes swelling and irritation in the esophagus. Early on, this often leads to a range of upper GI symptoms — including poor growth or failure to thrive in young children, abdominal pain, nausea, and symptoms that can mimic reflux.   [5:58] In older kids, symptoms are more about trouble swallowing. That's because the swelling that happens initially, over time, may turn into scar tissue. So the esophagus can narrow and cause swallowing symptoms like food impaction.   [6:16] Ryan speaks of living with EoE for decades and trying the full range of treatment options: food elimination, PPIs, steroids, and, more recently, biologics.   [6:36] Dr. Dellon says Ryan's history is a good overview of how EoE is treated. There are two general approaches to treating the underlying condition: using medicines and/or eliminating foods that we think may trigger EoE from the diet.   [6:57] For a lot of people, EoE is a food-triggered allergic condition.   [7:01] The other thing that has to happen in parallel is surveying for scar tissue in the esophagus. If that's present and people have trouble swallowing, sometimes stretching the esophagus is needed through esophageal dilation.   [7:14] There are three categories of medicines used for treatment. Proton pump inhibitors are reflux meds, but they also have an anti-allergy effect in the esophagus.   [7:29] Topical steroids are used to coat the esophagus and produce an anti-inflammatory effect. The FDA has approved a budesonide oral suspension for that.   [7:39] Biologics, which are generally systemic medications, often injectable, can target different allergic factors. Dupilumab is approved now, and there are other biologics that are being researched as potential treatments.   [7:51] Even though EoE is considered an allergic condition, we don't have a test to tell people what they are allergic to. If it's a food allergy, we do an empiric elimination diet because allergy tests aren't accurate enough to tell us what the EoE triggers are.   [8:10] People will eliminate foods that we know are the most common triggers, like milk protein, dairy, wheat, egg, soy, and other top allergens. You can create a diet like that and then have a response to the diet elimination.   [8:31] Dr. Jensen and Dr. Dellon recently published an abstract in the American Journal of Gastroenterology about people with EoE who are not taking any medicine for it. Dr. Jensen calls it a real-world data study, leveraging electronic health record patient data.   [8:51] It gives you an impression of what is actually happening, in terms of treatments for patients, as opposed to a randomized control trial, which is a fairly selected patient population. This is everybody who has been diagnosed, and then what happens with them.   [9:10] Because of that, it gives you a wide spectrum of patients. Some patients are going to be relatively asymptomatic. It may be that we arrived at their diagnosis while working them up for other potential diagnoses.   [9:28] Other patients are going to have rather significant impacts from the disease. We wanted to get an idea of what is actually happening out there with the full breadth of the patient population that is getting diagnosed with EoE.   [9:45] Dr. Jensen was not surprised to learn that there are patients who had no pharmacologic treatment.   [9:58] Some patients are relatively asymptomatic, and others are not interested in pursuing medications initially or are early in their disease process and still exploring dietary treatment options.   [10:28] Holly sees patients from infancy to geriatrics, and if they're not having symptoms, they wonder why bother treating it.   [10:42] Dr. Jensen says it's a point of debate on the implications of somebody who has the disease and goes untreated. What does that look like long-term? Are they going to develop more of that fibrostenotic pattern in their esophagus without treatment?   [11:07] This is a question we're still trying to answer. There is some suggestion that for some patients who don't manage their disease, we very well may be looking at a food impaction in the future.   [11:19] Dr. Dellon says we know overall for the population of EoE patients, but it's hard to know for a specific patient. We have a bunch of studies now that look at how long people have symptoms before they're diagnosed. There's a wide range.   [11:39] Some people get symptoms and get diagnosed right away. Others might have symptoms for 20 or 30 years that they ignore, or don't have access to healthcare, or the diagnosis is missed.   [11:51] What we see consistently is that people who may be diagnosed within a year or two may only have a 10 or 20% chance of having that stricture and scar tissue in the esophagus, whereas people who go 20 years, it might be 80% or more.   [12:06] It's not everybody who has EoE who might end up with that scar tissue, but certainly, it's suggested that it's a large majority.   [12:16] That's before diagnosis. We have data that shows that after diagnosis, if people go a long time without treatment or without being seen in care, they also have an increasing rate of developing strictures.    [12:29] In general, the idea is yes, you should treat EoE, because on average, people are going to develop scar tissue and more symptoms. For the patient in front of you with EoE but no symptoms, what are the chances it's going to get worse? You don't know.   [13:04] There are two caveats with that. The first is what we mean by s

Co-hosts Ryan Piansky, a graduate student and patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Sciences Advisory Council, interview Dr. Andrew Lee, Vice President, Clinical Research at Uniquity Bio, about Thymic Stromal Lymphopoietin (TSLP) and eosinophilic esophagitis (EOE). Disclaimer: The information provided in this podcast is designed to support, not replace, the relationship between listeners and their healthcare providers.

Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:49] Co-host Ryan Piansky introduces the episode, brought to you thanks to the support of Education Partners Bristol Myers Squibb, GSK, Sanofi, Regeneron, and Takeda. Ryan introduces co-host Holly Knotowicz.   [1:13] Holly introduces today's topic, Thymic Stromal Lymphopoietin (TSLP) and eosinophilic esophagitis (EOE), and today's guest, Dr. Andrew Lee, Vice President, Clinical Research at Uniquity Bio.   [1:36] Dr. Lee has nearly 20 years of experience in the clinical development of new vaccines, biologics, and drugs. Holly welcomes Dr. Lee.   [1:52] Dr. Lee trained in internal medicine and infectious diseases.   [1:58] Dr. Lee has been fascinated by the immune system and how it can protect people against infections, what happens when immunity is damaged, as in HIV and AIDS, and how to apply that knowledge to boost immunity with vaccines to prevent infections.   [2:16] Dr. Lee led the clinical development for a pediatric combination vaccine for infants and toddlers. It is approved in the U.S. and the EU.   [2:29] Dr. Lee led the Phase 3 Program for a monoclonal antibody to prevent RSV, a serious infection in infants. That antibody was approved in June 2025 for use in the U.S.   [2:44] In his current company, Dr. Lee leads research into approaches to counteract an overactive immune system. They're looking at anti-inflammatory approaches to diseases like asthma, EoE, and COPD.   [2:58] Dr. Lee directs the ongoing Phase 2 studies that they are running in those areas.   [3:28] Dr. Lee sees drug development as a chance to apply cutting-edge research to benefit people. He trained at Bellevue Hospital in New York City in the 1990s.   [3:40] When Dr. Lee started as an intern, there were dedicated ICU wards for AIDS patients because many of the sickest patients were dying of AIDS and its complications.    [3:52] Before the end of Dr. Lee's residency, they shut down those wards because the patients were on anti-retroviral medications and were doing so well that they were treated as outpatients. They didn't need dedicated ICUs for AIDS patients anymore.   [4:09] For Dr. Lee, that was a powerful example of how pharmaceutical research and drug regimen can impact patients' lives for the better by following the science. That's what drove Dr. Lee to go in the direction of research.   [4:48] Dr. Lee explains Thymic Stromal Lymphopoietin (TSLP). TSLP serves as an alarm signal for Type 2 or TH2 inflammation, a branch of the immune responses responsible for allergic responses and also immunity against parasites.   [5:17] When the cells that line the GI tract and the cells that line the airways in our lungs receive an insult or an injury, they get a danger signal, then they make TSLP.   [5:28] This signal activates other immune cells, like eosinophils and dendritic cells, which make other inflammatory signals or cytokines like IL-4, IL-13, and IL-5.   [5:47] That cascade leads to inflammation, which is designed to protect the body in response to the danger signal, but in some diseases, when there's continued exposure to allergens or irritants, that inflammation goes from being protective to being harmful.   [6:15] That continued inflammation, over the years, can lead to things like the thickened esophagus with EoE, or lungs that are less pliant and less able to expand, in respiratory diseases.   [6:48] Dr. Lee says he thinks of TSLP as being a master switch for this branch of immune responses. If you turn on TSLP, that turns on a lot of steps that lead to generating an allergic type of response.   [7:06] It's also the same type of immune response that can fight off parasite infections. It's the first step in a cascade of other steps generating that type of immune response.   [7:30] Dr. Lee says people have natural genetic variation in the genes that incur TSLP.   [7:38] Observational studies have found that some people with genetic variations that lead to higher levels of TSLP in their bodies had an increased risk for allergic inflammatory diseases like EoE, atopic dermatitis, and asthma.   [8:13] Studies like the one just mentioned point to TSLP being important for increased risk of developing atopic types of diseases like EoE and others. There's been some work done in the laboratory that shows that TSLP is important for activating eosinophils.    [8:38] There's accumulating evidence that TSLP activation leads to eosinophil activation, other immune cells, or white blood cells getting activated.   [9:07] Like a cascade, those cells turn on T-cells and B-cells, which are like vector cells. They lead to direct responses to fight off infections, in case that's the signal that leads to the turning on TSLP.   [9:48] Ryan refers to a paper published in the American Journal of Gastroenterology exploring the role of TSLP in an experimental mouse model of eosinophilic esophagitis. Ryan asks what the researchers were aiming to find.   [10:00] Dr. Lee says the researchers were looking at the genetic studies we talked about, the observational studies that are beginning to link more TSLP with more risk for EoE and those types of diseases.   [10:12] The other type of evidence that's accumulating is from in vitro (in glass) experiments or test tube experiments, where you take a couple of cells that you think are relevant to what's going on.   [10:28] For example, you could get some esophageal cells and a couple of immune cells, and put TSLP into the mix, and you see that TSLP leads to activation of those immune cells and that leads to some effects on the esophageal cells.   [10:42] Those are nice studies, but they're very simplified compared to what you can do in the body. These researchers were interested in extending those initial observations from other studies, but working in the more realistic situation of a mouse model.   [11:00] You have the whole body of the mouse being involved. You can explore what TSLP is doing and model a disease that closely mimics what's happening with EoE in humans.   [12:23] They recreated the situation of what seems to be happening in EoE in people. We haven't identified it specifically, but there's some sort of food allergen in patients with EoE that the immune system is set off by.   [12:55] What researchers are observing in this paper is that in these mice that were treated with oxazolone, there is inflammation in the esophagus, an increase in TSLP levels, and eosinophils going into the esophageal tissues.   [13:15] Dr. Lee says, that's one of the main ways we diagnose EoE; we take a biopsy of the esophagus and count how many eosinophils there are. Researchers saw similar findings. The eosinophil count in the esophageal tissues went way up in these mice.    [13:34] Researchers also saw other findings in these mice that are very similar to EoE in humans, such as the esophageal cells lining the esophagus proliferating. They even saw that new blood vessels were being created in that tissue that's getting inflamed.   [14:00] Dr. Lee thinks it's a very nice paper because it shows that correlation: Increase TSLP and you see these eosinophils going to the esophagus, and these changes that are very reminiscent of what we see in people with EoE.   [14:51] In this paper, the mice made the TSLP, and researchers were able to measure the TSLP in the esophageal tissue. The researchers didn't introduce TSLP into the mice. The mice made the TSLP in response to being repeatedly exposed to oxazolone.   [15:20] That's key to the importance of the laboratory work. The fact that the TSLP is made by the mice is important. It makes it a very realistic model for what we're seeing in people.   [15:41] In science, we like to see correlation. The researchers showed a nice correlation.   [15:46] When TSLP went up in these mice, and the mice were making more TSLP on their own, at the same time, they saw all these changes in the esophagus that look a lot like what EoE looks like in people.    [16:01] They saw the eosinophils coming into the esophagus. They saw the inflammation go up in the esophagus. What Dr. Lee liked about this paper is that they continued the story.   [16:15] The researchers took something that decreases TSLP levels, an antibody that binds to and blocks TSLP, and when they did that, they saw the TSLP levels come down to half the peak level.   [16:35] Then they saw improvement in the inflammation in the esophagus. They saw that the amount of eosinophils decreased, and the multiplication of the esophageal cells went down. The number of new blood vessels went down after the TSLP was reduced.   [16:53] Dr. Lee says, you see correlation. The second part is evidence for causation. When you take TSLP away, things get better. That gives us a lot of confidence that this is a real finding. It's not just observational. There is causation evidence here.   [18:26] Ryan asks if cutting TSLP also help reduce other immune response cells. Dr. Lee says TSLP is the master regulator for this Type 2 inflammation. It definitely touches and influences other cells besides eosinophi

Co-hosts Ryan Piansky, a graduate student and patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Sciences Advisory Council, interview three high school students who made less invasive EoE diagnostics the focus of a science fair project.

Opinions and views of guests and co-hosts are their own.   Key Takeaways: [:51] Co-host Ryan Piansky introduces the episode, brought to you thanks to the support of Education Partners Bristol Myers Squibb, GSK, Sanofi, Regeneron, and Takeda. Ryan introduces co-host Holly Knotowicz.   [1:08] Holly introduces today's guests, three high school students from Texas who made EoE diagnostics the focus of a science fair project: Leyna, Nhu, and Jaden.   [1:47] Leyna, Nhu, and Jaden are best friends. Nhu was diagnosed with EoE last summer. Leyna said Nhu told them it took a long time for the doctors to diagnose her because they thought it could be different conditions.   [2:07] Nhu told them about her appointments and her endoscopy procedures. She had to miss school sometimes. Leyna and Jaden were concerned for her.   [2:22] Leyna took AP Bio. Her teacher was a sponsor for the science fair. Leyna thought this would be a meaningful project for the three friends to learn more about Nhu's condition.    [2:45] Holly shares that she wasn't diagnosed until her 20s, but she was sick for much of her childhood.   [3:13] Ryan shares that he was diagnosed when he was two, after two years of his parents taking him to different doctors and undergoing different tests.   [3:31] Nhu says it was hard to find a specialist. They found one and had to wait six months for an appointment. It was a long time, suffering from the effects of EoE with constant symptoms, a lot of heartburn, and painful vomiting.   [4:00] Nhu was diagnosed with EoE in her sophomore year of high school. Her friends have seen her endure a lot, but she's strong. Nhu had to miss an orchestra concert where she had a big solo, because of her EoE.   [4:32] Doctors thought Nhu could have something different, like H. Pylori or cyclic vomiting syndrome. They didn't have clear answers, which was confusing and frustrating for her family.   [4:50] Holly talks about how difficult it was for her to get a diagnosis, and how she was told she was vomiting to get attention. She shared her reaction when diagnosed. She would like someone to do a research study about the pain tolerance of people with EoE.   [5:41] Leyna says junior year is the hardest year of high school. She doesn't know how Nhu survived physics and AP classes with EoE on top of it, and making up late work.   [6:14] Nhu takes a weekly injection. Her symptoms happen almost monthly. Sometimes she misses school for two weeks and has to catch up on work. Leyna and Jaden help her with her schoolwork.   [6:47] Ryan shared how he missed a third of his senior year in high school. He's now on an injectable biologic that has helped him a lot. That treatment option wasn't available when he was in high school. Having supportive friends to send him his schoolwork and keep him up-to-date was very helpful.   [7:11] Ryan explains the esophageal string test (EST). This is a tool that was developed to help monitor eosinophilic esophagitis (EoE). The test works by having the patient swallow a capsule about the size of a Tic Tac that has a string attached.   [7:25] The capsule dissolves in the stomach while the string stays in place in the esophagus. After about an hour, it's gently removed. Along the way, the string collects samples from the lining of the esophagus, which are reviewed, similarly to a biopsy.   [7:37] Holly adds that what makes the string test unique is that it doesn't require an endoscope, anesthesia, or recovery time, things that usually come with a traditional endoscopy and biopsy.   [7:46] It's now being used with patients as young as four years old. While some people might feel some minor discomfort, it's generally much easier for regular monitoring than an endoscopy.   [7:57] Holly explains that she was involved in testing the device and developing a swallowing protocol for it at Children's Hospital of Colorado. We will talk more about this later in the episode.   [8:06] Ryan adds, to learn more about the development of the string test, listen to episode 26 of this podcast.   [8:10] The string test is one of multiple, less-invasive monitoring tools for eosinophilic esophagitis. Others include the sponge test and unsedated trans-nasal endoscopy.   [8:19] To learn more about unsedated transnasal endoscopy, listen to episodes 19 and 20, where we talk to clinicians and patients about this method.   [8:27] During that episode, we talked to the developers of the EST.   [8:38] Jaden tells how he, Leyna, and Nhu brainstormed ideas and decided to base their project specifically on how to diagnose EoE in a less invasive way than endoscopies.   [9:12] Before this project, they were not familiar with the EST. Nhu says her only option for diagnosis was an endoscopy.   [9:21] Holly says it's still like that in Maine. She came from an area of the country where the EST was researched, and it's interesting to her that she doesn't have access to it now.   [9:37] What appealed to the group about the EST as an alternative to endoscopies is that it was so different. There are so many advanced technologies, and the EST is just a capsule taped to a string. It is simple but innovative.   [10:13] Real Talk: Eosinophilic Diseases had Drs. Robin Shandas and Steven Ackerman, who were instrumental in the development of the esophageal string test, as guests on episode 26 of this podcast. Ryan encourages listeners to check out that episode at apfed.org/podcasts.   [10:42] They searched for keywords and analyzed a variety of scholarly literature. They collected a lot of data from Dr. Ackerman's papers.   [11:10] They also reached out to gastroenterologists on social media. A hard thing about science fair projects is coming up with an experiment. They didn't know what they could do just with compiled research, but they had a great sponsor who helped along the way.   [11:56] Leyna says they trusted that the doctors they reached out to on social media were competent in their understanding of different diagnostic methods. She notes that different locations may have different resources and different biases.   [12:14] Leyna says they talked to doctors in the U.S. and from different countries, including India and Mexico. She commented that communities in Mexico might not have the same resources as communities in the U.S. or India. That might change their understanding of the EST.   [12:33] We might have different biases because we don't have the same technology to research and find the same things about the EST.   [13:12] Leyna says they reached out to doctors on social media, but didn't get responses from that many doctors. Reaching out to patients would be a good thing if they want to continue the project.   [14:00] Jaden says most of the data they found was from Dr. Ackerman, including a survey he did comparing the data of the EST and the biopsies.   [14:10] They found that the EST and the biopsies were relatively similar in terms of discovering the eosinophilic count and determining whether the EoE is active or inactive.   [15:30] They found differences between ESTs and biopsies in finding how much of a certain chemical is in the patient's cells.   [14:43] Leyna comments that one of the doctors they reached out to told them about the sponge test, another less invasive method. They didn't research the sponge test, but it sounded interesting.   [15:00] Ryan says there are a lot of cool new techniques that are being researched, like the transnasal endoscopy that goes in through the nose, the string test, and the sponge test.   [15:13] Leyna says the cool thing was hearing about all these methods. They had hypothesized that there are less invasive methods that may be better than endoscopies.   [15:27] They were not able to prove their hypothesis yet. They learned a lot of different things that could be beneficial.   [15:42] Holly points out that the transnasal endoscopy is not scary. It's also known as the unsedated endoscopy. Holly has done both the EST and the unsedated endoscopy,  and they each have pluses and minuses.   [16:15] Nhu explains how the team would meet at one of their houses, usually Leyna's house. One day, they watched Interstellar together, and the "Eureka moment" scene motivated them.   [16:41] They helped each other whenever necessary. When the project board was due, they all went to Leyna's house to work on the project board. They worked together as a team.   [16:51] Jaden analyzed a lot of the data. Leyna reached out to professors. Nhu helped Jaden understand some terms. On the day they presented the project, Nhu was sick in the hospital, which made them sad. They included a photo of her on the project board.   [17:28] Holly says that although Nhu wasn't there, it may have helped people know how sick EoE can make you feel.   [18:28] Leyna says one of the doctors they reached through social media told them that endoscopies have lots of benefits. The biopsy samples give healthcare professionals a clear idea of how many eosinophils per high-powered field, a key indicator in diagnosing EoE.   [18:57] The diagnosis gives a baseline for starting treatment for the patient, monit

Description: Co-hosts Ryan Piansky, a graduate student and patient advocate living with eosinophilic esophagitis (EoE) and eosinophilic asthma, and Holly Knotowicz, a speech-language pathologist living with EoE who serves on APFED's Health Sciences Advisory Council, interview Anna Henderson, MD, a pediatric gastroenterologist at Northern Light Health in Maine, about bone mineral density in EoE patients. They discuss a paper she co-authored on the subject.

Ryan introduces co-host Holly Knotowicz.   [1:17] Holly introduces today's topic, eosinophilic esophagitis (EoE), and bone density.   [1:22] Holly introduces today's guest, Dr. Anna Henderson, a pediatric gastroenterologist at Northern Light Health in Maine.   [1:29] During her pediatric and pediatric gastroenterology training at Cincinnati Children's Hospital, she took a special interest in eosinophilic esophagitis. In 2019, Dr. Henderson received APFED's NASPGHAN Outstanding EGID Abstract Award.   [1:45] Holly, a feeding therapist in Maine, has referred many patients to Dr. Henderson and is excited to have her on the show.   [2:29] Dr. Henderson is a wife and mother. She loves to swim and loves the outdoors. She practices general pediatric GI in Bangor, Maine, at a community-based academic center.   [2:52] Her patient population is the northern two-thirds of Maine. Dr. Henderson feels it is rewarding to bring her expertise from Cincinnati to a community that may not otherwise have access to specialized care.   [3:13] Dr. Henderson's interest in EoE grew as a GI fellow at Cincinnati Children's. Her research focused on biomarkers for disease response to dietary therapies and EoE's relationship to bone health.   [3:36] As a fellow, Dr. Henderson rotated through different specialized clinics. She saw there were many unanswered questions about the disease process, areas to improve treatment options, and quality of life for the patients suffering from these diseases.   [4:00] Dr. Henderson saw many patients going through endoscopies. She saw the social barriers for patients following strict diets. She saw a huge need in EoE and jumped on it.   [4:20] Ryan grew up with EoE. He remembers the struggles of constant scopes, different treatment options, and dietary therapy. Many people struggled to find what was best for them before there was a good approved treatment.   [4:38] As part of Ryan's journey, he learned he has osteoporosis. He was diagnosed at age 18 or 19. His DEXA scan had such a low Z-score that they thought the machine was broken. He was retested.   [5:12] Dr. Henderson explains that bone mineral density is a key measure of bone health and strength. Denser bones contain more minerals and are stronger. A low bone mineral density means weaker bones. Weaker bones increase the risk of fracture.   [5:36] DEXA scan stands for Dual Energy X-ray Absorptiometry scan. It's a type of X-ray that takes 10 to 30 minutes. A machine scans over their bones. Typically, we're most interested in the lumbar spine and hip bones.   [5:56] The results are standardized to the patient's height and weight, with 0 being the average. A negative number means weaker bones than average for that patient's height and weight. Anything positive means stronger bones for that patient's height and weight.   [6:34] A lot of things can affect a patient's bone mineral density: genetics, dietary history, calcium and Vitamin D intake, and medications, including steroid use. Prednisone is a big risk factor for bone disease.   [7:07] Other risk factors are medical and auto-immune conditions, like celiac disease, and age. Any patient will have their highest bone density in their 20s to 30s. Females typically have lower bone mineral density than males.   [7:26] The last factor is lifestyle. Patients who are more active and do weight-bearing exercises will have higher bone mineral density than patients who have more of a sedentary lifestyle.   [7:56] Ryan was told his bone mineral density issues were probably a side-effect of the long-term steroids he was on for his EoE. Ryan is now on benralizumab for eosinophilic asthma. He is off steroids.   [8:36] Dr. Henderson says the research is needed to find causes of bone mineral density loss besides glucocorticoids.   [8:45] EoE patients are on swallowed steroids, fluticasone, budesonide, etc. Other patients are on steroids for asthma, eczema, and allergic rhinitis. These may be intranasal steroids or topical steroids.   [9:01] Dr. Henderson says we wondered whether or not all of those steroids and those combined risks put the EoE population at risk for low bone mineral density. There's not a lot published in that area.   [9:14] We know that proton pump inhibitors can increase the risk of low bone mineral density. A lot of EoE patients are on proton pump inhibitors.   [9:23] That was where Dr. Henderson's interest started. She didn't have a great way to screen for bone mineral density issues or even know if it was a problem in her patients more than was expected in a typical patient population.   [9:57] Holly wasn't diagnosed with EoE until she was in her late 20s. She was undiagnosed but was given prednisone for her problems. Now she wonders if she should get a DEXA scan.   [10:15] Holly hopes the listeners will learn something and advocate for themselves or for their children.   [10:52] If a patient is concerned about their bone mineral density, talking to your PCP is a perfect place to start. They can discuss the risk factors and order a DEXA scan and interpret it, if needed.   [11:11] If osteoporosis is diagnosed, you should see an endocrinologist, specifically to discuss therapy, including medications called bisphosphonates.   [11:36] From an EoE perspective, patients can talk to their gastroenterologist about what bone mineral density risk factors may be and if multiple risk factors exist. Gastroenterologists are also more than capable of ordering DEXA scans and helping their patients along that journey.   [11:53] A DEXA scan is typically the way to measure bone mineral density. It's low radiation, it's easy, it's fast, and relatively inexpensive.   [12:10] It's also useful in following up over time in response to different interventions, whether or not that's stopping medications or starting medications.   [12:30] Dr. Henderson co-authored a paper in the Journal of Pediatric Gastroenterology and Nutrition, called "Prevalence and Predictors of Compromised Bone Mineral Density in Pediatric Eosinophilic Esophagitis." The study looked at potential variables.   [12:59] The researchers were looking at chronic systemic steroid use. They thought it was an issue in their patients, especially patients with multiple atopic diseases like asthma, eczema, and allergic rhinitis. That's where the study started.   [13:22] Over the years, proton pump inhibitors have become more ubiquitous, and more research has come out. The study tried to find out if this was an issue or not. There weren't any guidelines for following these patients, as it was a retrospective study.    [13:42] At the time, Dr. Henderson was at a large institution with a huge EoE population. She saw that she could do a study and gather a lot of information on a large population of patients. Studies like this are the start of figuring out the guidelines for the future.   [14:34] Dr. Henderson wanted to determine whether pediatric patients with EoE had a lower-than-expected bone mineral density, compared to their peers. [14:44] Then, if there were deficits, she wanted to determine where they were more pronounced. Were they more pronounced in certain subgroups of patients with EoE?   [14:59] Were they patients with an elemental diet? Patients with an elimination diet? Were they patients on steroids or PPIs? Were they patients with multiple atopic diseases? Is low bone mineral density just a manifestation of their disease processes?   [15:14] Do patients with active EoE have a greater propensity to have low bone mineral density? The study was diving into see what the potential risk factors are for this patient population.   [15:45] The study was a retrospective chart review. They looked at patients aged 3 to 21. You can't do a DEXA scan on a younger patient, and 21 is when people leave pediatrics.   [16:03] These were all patients who had the diagnosis of EoE and were seen at Cincinnati Children's in the period between 2014 and 2017. That period enabled full ability for chart review. Then they looked at the patients who had DEXA scans.   [16:20] They did a manual chart review of all of the patients and tried to tease out what the potential exposures were. They looked at demographics, age, sex, the age of the diagnosis of EoE, medications used, such as PPIs, and all different swallowed steroids.   [16:44] They got as complete a dietary history as they could: whether or not patients were on an elemental diet, whether that was a full elemental diet, whether they were on a five-food, six-food, or cow's milk elimination diet.   [16:58] They teased out as much as they could. One of the limitations of a retrospective chart review is that you can't get some of the details, compared to doing a prospective study. For example, they couldn't tease out the dosing or length of therapy, as they wou

Ryan introduces co-host Holly Knotowicz.   [1:17] Holly introduces today's topic, common nutritional deficiencies that affect those with eosinophilic gastrointestinal diseases that occur in the GI tract lower than the esophagus (non-EoE EGIDs).   [1:31] Holly introduces today's guest, Bethany Doerfler, a clinical research dietician specializing in lifestyle management of digestive diseases, including gastroesophageal reflux disease, motility disorders, and eosinophilic diseases.   [1:45] Bethany currently practices as part of a multi-disciplinary team in a digestive health institute at Northwestern Medicine.   [2:03] Bethany began working with this disorder almost 20 years ago. She worked with Dr. Gonsalves and Dr. Hirano at Northwestern. Dr. Gonsalves invited her to work with EoE patients. Bethany had not heard of EoE.   [2:59] Bethany says the lens that we've used to look at food as the trigger and also a therapeutic agent in the esophagus, we're looking at in non-EoE EGIDs as well; at the same time, trying to make sure that we're honoring the other parts of our patient's lives.   [3:27] Before Bethany started working in GI at Northwestern, she worked in the Wellness Institute, doing nutrition for patients at Northwestern. Bethany has a research background in epidemiology and she wanted to see better nutrition research in GI.   [3:56] Through a friend, Bethany connected with the Chief of GI at that point. Northwestern had never had a dietician working in GI.   [4:08] Bethany is pleased to see a trend in healthcare of thinking about the patient as a whole person, including diet, psychological wellness, physical health, exercise, sleep, and more. Bethany wanted to see more research on GI disorders.   [4:38] Bethany says that eosinophils in the esophagus indicate that something is irritating the tissues, such as reflux, food triggers, aeroallergens, and other things.   [4:58] Eosinophils do belong in the stomach, the small intestine, and the colon. The challenge for researchers has been, how many, where are they supposed to live, and what are they supposed to look like.   [5:10] There is eosinophilic gastritis, where eosinophils can infiltrate the stomach, causing a lot of inflammatory responses that make patients sick. We see that in all parts of the small intestine and less commonly, in the colon, as well.   [5:32] It's a good reminder for listeners that eosinophils are white blood cells. When they're in the tissues, they can swell things up and cause the body to have this inflammatory response in these lower GI tract organs.   [5:49] The symptoms patients can experience are vomiting, diarrhea, and abdominal pain, among other things.   [6:14] The nomenclature for this subset of eosinophil-associated diseases has changed and Bethany says to hang tight, there is lots of work underway to nail this down further in the next couple of months to a year.   [6:29] The last guidelines were published by a Delphi Consensus in 2022. The experts in the field got together and voted on the scientific accuracy of certain statements to develop cut points for how to grade.   [6:48] The experts are asking questions like: What counts as eosinophilic gastritis? What do we think are some of the symptoms and the clinical findings so that we all are looking at things through the same lens?   [7:02] To get to these consensus statements, there's a lot of discussion, agreement, and good collegial discussions about making sure that we're looking at this accurately.   [7:12] We're trying to give the right names to the right disorders and give clear diagnostic criteria, so that we're helping our patients get a diagnosis, and we're not labeling something incorrectly and sticking someone with an inaccurate diagnosis.   [7:36] The proper terminology is eosinophilic gastritis in the stomach, eosinophilic enteritis in the small intestine, eosinophilic colitis in the colon, and eosinophilic gastroenteritis where the stomach and the small bowel are involved.   [7:53] There's more to come on the clinical criteria of what makes that diagnosis but we're getting the names and the numbers right.   [8:03] Holly agrees that having the symptoms given a named diagnosis is important to patients, knowing that researchers are looking into their illness.   [9:00] Bethany notes that the diagnosis also means that there are opportunities for medical therapy, cut points for which medicines or therapies work or not, and billing codes. If we can't bill insurance companies, patients might not get certain services.    [9:28] Ryan tells how beneficial it was for him to have access to multi-disciplinary teams and see specialists he might not have seen without the proper diagnosis and just thought it was a GI issue. He was fortunate to see a dietician and start dietary therapy.   [9:53] Bethany says the dietician's priority is the patient's health and wellness.   [10:13] These disorders carry clinical non-gastrointestinal manifestations: fatigue, concern over what to eat, food access issues, family support, and other food allergies. These are important things for a dietician to consider.   [10:37] Are patients growing as they should? Do they feel like they have enough to eat? Do they feel excluded in social settings? There's a list of important things that we want to be looking at. That's why it's important to have a multi-disciplinary approach.   [11:07] First, Bethany wants to see that her patients are physically and nutritionally well. That's a priority if we're going to try to get rid of some of the food triggers that could be exacerbating the disease.   [11:20] Before Bethany takes anything out of someone's diet, she wants to make sure that they're getting enough of the good stuff to help them feel good and grow.   [11:29] From a diet therapy perspective, Bethany is trying to apply a food removal or substitution protocol to other spots outside the esophagus. They're seeing that some of the triggers are very similar, both in the stomach and small intestine.   [12:09] Dr. Gonsalves, Dr. Hirano, and Bethany did a study, The Elemental Study, where they wanted to uncover if food proteins carried the same trigger risk in the stomach and small intestine as they do in the esophagus.   [12:35] They put their patients on a hypoallergenic elemental formula for a period, followed up, and looked at their biopsies of the stomach and small intestine. Fifteen wonderful patients made it through the trial.   [12:56] One hundred percent of the patients achieved disease remission and felt better. There were some genetic alterations in the patients. Then they started the process of reintroducing foods over the year.   [13:15] That was not part of the original grant but was the team's clinical interest to see what it is that people are allergic to. Some of the common suspects: wheat, dairy, eggs, soy, and nuts, were found to be very common triggers for EoG and EoN, as well.   [13:47] The benefit of working with a dietician as part of your team is, first, we can remediate things the disease has caused nutritionally, and second, we can think about how diet can be a therapeutic tool to use with medications or instead of medication.   [14:15] If you want to use nutrition therapeutically, you don't have to stay there if it's not the right time to be taking things out of your diet. We have some good, safe, medical therapies. You can find your food triggers but you don't have to pick that lane forever.   [14:42] Holly and Ryan relate their experiences with traveling abroad and going on medical therapies when they can't stay on their diets.   [15:57] Bethany says low levels of vitamins and minerals in the blood can be caused by a disorder or an elimination diet. In the U.S., dairy is the biggest source of protein for young kids. It's also the biggest source of calcium and vitamin D.   [16:22] Dieticians often say, if we are going to use dietary therapy for EoE or non-EoE EGIDs, we have to think of this as a substitution diet. If we remove something, we have to replace it with something equally nutrient-dense.   [16:39] Bethany and her group look at serum values of Vitamin D, B12, and iron they assess for patients. For kids, instead of drawing blood, they piece together what they're taking against what they need and see if there are gaps to fill with food or supplements.   [17:32] In patients with non-EoE EGIDs, Bethany says we see the disease intersect with the food supply. When we take milk out, we're cutting the biggest source of calcium and Vitamin D. We have to replace calcium and Vitamin D.   [17:55] In the 1950s, a public health law allowed wheat to be enriched with folic acid and other B vitamins and iron. When we cut out wheat, our patients are
