Eosinophils are a type of white blood cell that play a role in immune responses and help fight off infections. When these cells build up and cause inflammation in the digestive system, tissues, organs, and/or bloodstream, without a known cause, it may be the result of an eosinophil-associated disease. Join the American Partnership for Eosinophilic Disorders (APFED) for a series of conversations with researchers, clinicians, patients, and other community members as we discuss practical strategies for disease management and treatments, research, and other topics of interest.

Key Takeaways:
[:50] Co-host Ryan Piansky introduces the episode, brought to you thanks to the support of Education Partners Bristol Myers Squibb, Sanofi, Regeneron, and Takeda. 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 would have liked.
[17:19] They classified those exposures as whether or not the patient was ever exposed to those medications, whether or not they were taking them at the time of the DEXA scan, or if they had been exposed within the year before the DEXA scan.
[17:40] They also looked at whether the patients had other comorbid atopic disorders, to see if those played a role, as well.
[18:03] The study found that there was a slightly lower-than-expected bone mineral density in the patients. The score was -0.55, lower than average but not diagnostic of a low bone mineral density, which would be -2 or below.
[18:27] There were 23 patients with low bone mineral density scores of -2 or below. That was 8.6% of the study patients. Typically, only 2.5% of the population would have that score. It was hard to tease out the specific risk factors in a small population of 23.
[18:57] They looked at what the specific risk factors were that were associated with low bone mineral density, or bone mineral density in general.
[19:12] After moving from Colorado, Holly has transferred to a new care team, and doctors wanted her baseline Vitamin D and Calcium levels. No one had ever tested that on her before. Dr. Henderson says it’s hard because there’s nothing published on what to do.
[19:58] The biggest surprise in the study was that swallowed steroids, or even combined steroid exposure, didn’t have any effect on bone mineral density. That was reassuring, in light of what is known about glucocorticoid use.
[20:16] The impact of PPI use was interesting. The study found that any lifetime use of PPIs did seem to decrease bone mineral density. It was difficult to tease out the dosing and the time that a patient was on PPIs.
[20:34] Dr. Henderson thinks that any lifetime use of PPIs is more of a representation of their cumulative use of PPIs. At the time of the study, from 2014 to 2017, PPIs were still very much first-line therapy for EoE; 97% of the study patients had taken PPIs at some time.
[21:02] There are so many more options now for therapy when a patient has a new diagnosis of EoE, especially with dupilumab now being an option.
[21:11] Dr. Henderson speaks of patients who started on PPIs and have stayed on them for years. This study allows her to question whether we need to continue patients on PPIs. When do we discuss weaning patients off PPIs, if appropriate?
[22:05] Ryan says these podcasts are a great opportunity for the community at large and also for the hosts. He just wrote himself a note to ask his endocrinologist about coming off PPIs.
[22:43] Dr. Henderson says that glucocorticoid use is a known risk factor for low bone mineral density and osteoporosis. In the asthma population, inhaled steroids can slightly decrease someone’s growth potential while the patient is taking them.
[23:10] From those two facts, it was thought that swallowed steroids would have a similar effect. But since they’re swallowed and not systemic, maybe things are different.
[23:23] It was reassuring to Dr. Henderson that what her study found was that the swallowed steroid didn’t affect bone mineral density. There was one other study that found that swallowed steroids for EoE did not affect someone’s height.
[23:51] Dr. Henderson clarifies that glucocorticoids include systemic steroids like prednisone and hydrocortisone.
[23:57] Based on Dr. Henderson’s retrospective study, fluticasone as a swallowed steroid did not affect bone mineral density. It was hard to tease out the dosing, but the cumulative use did not seem to result in a deficit for bone mineral density.
[24:16] Holly shared that when she tells a family of a child she works with that the child’s gastroenterologist will likely recommend steroids, she will now give them the two papers Dr. Henderson mentioned. There are different types of steroids. The average person doesn’t know the difference.
[25:15] Dr. Henderson thinks that for patients who have multiple risk factors for low bone mineral density, it is reasonable to have a conversation about bone health with their gastroenterologist to see whether or not a DEXA scan would be worth it.
[25:56] If low bone mineral density is found, that needs to be followed up on.
[26:03] There are no great guidelines, but this study is a good start on what these potential risk factors are. We need some more prospective studies to look at these risk factors in more detail than Dr. Henderson’s team teased out in this retrospective study.
[26:23] Dr. Henderson tells how important it is for patients to participate in prospective longitudinal studies for developing future guidelines.
[26:34] Holly points out that a lot of patients are on restrictive diets. It’s important to think about the whole picture if you are starting a medication or an elimination, or a restricted diet. You have to think about the impact on your body, overall.
[27:11] People don’t think of dietary therapy as medication, but it has risks and benefits involved, like a medication.
[27:50] Dr. Henderson says, in general, lifestyle management is the best strategy for managing bone health. Stay as active as you can with weight-bearing exercises and eating a well-balanced diet. If you are on a restrictive diet, make sure it’s well-balanced.
[28:12] Dr. Henderson says a lot of our patients have feeding disorders, so they see feeding specialists like Holly. A balanced diet is hard when kids are very selective in their eating habits.
[29:10] Dr. Henderson says calcium and Vitamin D are the first steps in how we treat patients with low bone mineral density. A patient who is struggling with osteoporosis needs to discuss it with their endocrinologist for medications beyond supplementation.
[29:31] Ryan reminds listeners who are patients always to consult with their medical team. Don’t go changing anything up just because of what we’re talking about here. Ask your care team some good questions.
[29:47] Dr. Henderson would like families to be aware, first, that some patients with EoE will have bone mineral density loss, especially if they are on PPIs and restrictive diets. They should start having those discussions with their providers.
[30:04] Second, Dr. Henderson would like families to be reassured that swallowed steroids and combined steroid exposure didn’t have an impact on bone mineral density. Everyone can take that away from today’s chat.
[30:18] Lastly, Dr. Henderson gives another plug for patient participation in prospective studies, if they’re presented with the opportunity. It’s super important to be able to gather more information and make guidelines better for our patients.
[30:35] Holly thanks Dr. Henderson for coming on Real Talk — Eosinophilic Diseases and sharing her insights on bone mineral density, and supporting patients in Maine.
[30:57] Dr. Henderson will continue to focus on the clinical side. She loves doing outreach clinics in rural Maine. It’s rewarding, getting to meet all of these patients and taking care of patients who would otherwise have to travel hours to see a provider.
[32:01] Ryan thinks the listeners got a lot out of this. For our listeners who would like to learn more about eosinophilic disorders, please visit APFED.org and check out the links in the show notes.

Key Takeaways:
[:48] Co-host Ryan Piansky welcomes co-host Holly Knotowicz. Holly introduces Dr. Amanda Muir, an Assistant Professor of Pediatrics at the Children’s Hospital of Philadelphia (CHOP). She has a translational lab that investigates esophageal remodeling in the setting of EoE. Holly thanks Dr. Muir for joining us today.
[1:51] Dr. Muir became interested in eosinophilic disorders as a GI Fellow. There were so many patients with eosinophilic esophagitis and eosinophilic gastrointestinal diseases but there weren’t many good therapies and little was known about the long-term results for children.
[2:24] Dr. Muir’s first eosinophilic interest was eosinophilic esophagitis. She joined a lab that was looking at how the esophagus changes over time in the setting of inflammation. After being in the lab, training, and learning all the skills and techniques, she was able to launch her career and lab.
[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 aren’t getting enough iron or B vitamins. We have to replace those.
[18:16] For patients who have eosinophils in their stomach and small intestine, their absorption in the small bowel may be directly impacted.
[18:26] People can have low levels of protein in their blood, maybe because they’re eating insufficient protein or maybe because the disease doesn’t allow them to absorb protein sufficiently when there’s swelling in the small intestine.
[18:44] There are other nutrients, like zinc, for people who have diarrhea, and magnesium if you can’t eat a lot of whole grains and nuts, There are quite a few nutrients that Bethany is broadly looking at.
[18:54] Based on the absorption in the small intestine, patients’ doctors need to look at their B12, folic acid, iron levels, and Vitamin D.
[19:12] Holly loves Bethany’s terminology of replacing, not just eliminating, foods. She will use that terminology with her patients to make it feel more supportive for them.
[20:40] A lot of people want to get all their nutrients through their food. That’s not always practical. Vitamin D is hard to get exclusively in your diet if you’re not drinking milk or eating wild-caught fish. You have to rely on fortified foods or add supplements.
[21:15] One, we want to take a look at your diet and ask how are your calories. We want to make sure you’re eating enough. Two, if we suspect there are some vitamin deficiencies, we check your blood or just empirically supplement you.
[21:36] Supplementation should be done carefully. There are some vitamins where you can get too much of a good thing. Vitamins stored in the fat need to be at levels sufficient for repletion, dictated by age and gender. Dieticians know what to recommend.
[22:19] For patients who have non-EoE EGIDs, some have tentative swallowing, so Bethany tries to do as many liquid or chewable safe options for supplements as possible.
[23:46] Holly works with patients who have feeding difficulty, so she appreciates the liquid and chewable supplements for easier swallowing and quicker absorption.
[24:08] Bethany mentions that some fortified oat, corn, and rice breakfast cereals are highly enriched with B vitamins and iron. Look at the labels. It can be a way to layer in more vitamins without purchasing a supplement.
[25:24] Holly doesn’t think patients understand how valuable a good dietician can be. She had one patient with celiac who was taking a supplement with gluten in it! She reminds listeners to always consult your care team before making any changes to your treatment plan.
[25:59] Bethany’s favorite thing to talk about is foods and where to find what. If listeners have questions, she is happy to post answers on the website.
[26:25] The American Academy of Pediatrics says a cup of vitamin-fortified juice a day is not too much sugar and is a good source of Vitamin C and other nutrients. The calcium and Vitamin D you get from a cup of fortified juice is very value-available.
[26:46] In the non-dairy drink world, some are nicely fortified and some are not. If you make your almond milk, you’re missing out on the fortifications.
[27:11] Bethany likes some of the fortified juices and some of the enriched non-dairy milk options. Those are the best ways to get calcium and Vitamin D for people who need calories. Instead of water with meals, substitute an enriched drink with meals.
[27:33] Some people struggle with protein, probably because of their level of food restriction. The typical animal proteins are great. If you can do soy, a cup of soy milk has eight grams of protein. Soy is a complete protein that mimics animal proteins.
[28:04] Cook your cereal in soy milk. Use it as the base of a smoothie. This is before getting into protein powders. Try legume-based proteins, if you can handle legumes. Your supplements have to be personalized. That’s the tricky part.
[28:30] If you have a lot of food allergies or intolerances, it may be worth talking to your gastroenterologist, allergist, or dietician about adding elemental formula as a supplement. Bethany uses it often with food allergy patients as a safe supplement.
[29:31] Bethany primarily treats adults but also young adults transitioning from the pediatric side into the adult world. Sometimes a feeding difficulty follows patients into adult treatment. We need everyone at the table to treat this immune-mediated disease.
[30:32] Patient advocacy groups like APFED have ways to help you find dieticians. Also, the Academy of Nutrition and Dietetics has “Find a Specialist” on their website. Eatright.org. Dieticians can do telehealth if you are not near one.
[31:45] If the practice that you’re in doesn’t have a dietician, you could gently suggest they have one join the practice, or consult with the practice. Patient advocacy is strong.
[33:12] Bethany talks about getting an appointment with a dietician. On the pediatric side, it has to do with the billing code. Ask your insurance if they cover medical nutrition therapy, Billing Code 97802, and for which diseases. Insurance may have stipulations.
[34:14] If medical nutrition therapy is not a covered benefit, ask the dietician if they can do a sliding scale. Holly says she has seen plans in several states where the patient can use the HSA or FSA card to pay for medical nutrition therapy.
[34:49] Bethany believes in the pediatric world, where growth and development are concerns, there’s a little bit better coverage.
[34:59] On the adult side, if Bethany has other diagnoses, like high blood pressure, or diabetes, she is also billing for those because she makes sure what she recommends is also in line with what is good for their heart and wellness in general.
[35:55] Bethany was intrigued to learn food proteins do trigger disease activity for our patients in the stomach and small intestine, just as in the esophagus.
[36:20] In the Elemental Trial, they were surprised to learn people with non-EoE EGIDs had more allergies than expected. They were more likely to have more than just one or two. They were also more likely to have rare food allergies like legumes or grains.
[36:43] A patient may want to learn all their food triggers, but they may be a highly allergic person and it may not be worth trying to remove all their food triggers.
[37:06] Bethany wants to remind listeners that the diet approach should be a substitution diet. If you take things out, you’ve got to replace them with other plants.
[37:18] There’s great crossover nutrition between fruits and vegetables. Seeds are great as a fill-in for nuts. There are plenty of other whole grains out there besides wheat. There are lots of good ways to get that nutritional balance into your diet.
[37:31] For anyone who’s eliminating a food group, even if you’re substituting it, it’s a good idea to talk to your doctor about filling in with a good multivitamin, multimineral supplement.
[37:59] Bethany says it’s fun working with colleagues to look for other ways to look at this nutrition lens for patients with Non-EoE EGIDs.
[38:14] They are looking at noninvasive ways to find eosinophils to go faster with helping people find their food triggers without having to scope them.
[38:28] Bethany is hoping with that research to be able to help people learn how they can cheat, like having pizza once a month if they are allergic to dairy. That’s a question for your care team, but we don’t have a great science-based way to answer that.
[38:53] As we study more noninvasive ways to get at eosinophilic activity, we can give patients a little bit more freedom and quality of life. That’s what Bethany is working on next.

[2:11] Dr. Jensen’s background is in maternal and child health. She was interested in how early life exposures alter colonization of the gut microbiome and how that can lead to immune dysregulation.
[2:33] Dr. Jensen became interested in EoE and eosinophilic gastrointestinal diseases because her family members had been affected by these conditions and researchers knew next to nothing about the pathogenesis of these conditions.
[2:52] Dr. Jensen’s early research explored early life exposures that relate to the development of eosinophilic gastrointestinal diseases.
[3:02] That research paved the way for a variety of ongoing research studies in Denmark, the U.S., and through the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR).
[3:30] The Eosinophilic Gastrointestinal Disorders (EGID) Partners Registry is a registry of individuals who have been diagnosed with any one of the eosinophilic gastrointestinal diseases or multiple ones.
[4:21] The registry is also for individuals who haven’t been diagnosed. The EGID Partners Registry gives a voice to individuals who are living with these conditions, in terms of directing where we go with research and asking patient-centered questions.
[4:58] To participate in the registry, go to EGIDPartners.org and register. Once you have registered you will receive a link to a questionnaire. The questionnaire can seem long.
[5:23] After the first questionnaire, the registry sometimes asks for updates to your baseline information and asks new questions that have been suggested by others.
[5:45] The EGID Partners Registry has a Scientific Advisory Committee, and patient advocacy groups, including APFED, physicians, and researchers, who direct where to go with the rich data that has been collected.
[6:07] Some of the questions are specific and asked by registry members with individual interests. Some of the questions are directed by input received by patient advocacy groups.
[6:48] After collecting these data, EGID Partners analyzes them and disseminates them by presenting them at meetings to get information to providers and individuals affected by these conditions.
[7:50] EGID Partners Registry did a study titled “Extraintestinal Symptoms of Pain in Eosinophilic Gastrointestinal Diseases” and published a poster on it. They explored joint pain, leg pain, and headaches, to see if they were related to an eosinophilic condition.
[8:29] They studied pain severity and frequency as well as migraines. A high proportion of individuals reported pain. They studied those with EoE only and those with another EGID, including eosinophilic gastritis, eosinophilic enteritis, and eosinophilic colitis.
[9:06] The second group included individuals with or without EoE. In general, patients who have one of these non-EoE EGIDS, with or without EoE, tend to experience more frequent pain and more severe pain.
[9:30] They’ve also seen that result in looking at other comorbidities. It reinforces the idea that patients who have multi-segmental EGIDs, or one of these lower EGIDS, tend to experience, on average, more severe extraintestinal symptoms.
[10:39] The three areas of pain highlighted on the poster were legs, joints, and headaches. This was based on feedback from patients saying, “This is what we’re experiencing, is it something that you could look into?”
[10:48] It doesn’t preclude the possibility that there may be other types of extraintestinal manifestations that we should be looking at in the future.
[11:27] This study by the EGID Partners Registry feels very impactful to Dr. Jensen. It brings awareness to some of the challenges that individuals with these conditions are experiencing. Holly points out it’s a way for patients to get access to experts.
[12:20] In this study, the EGID Partners Registry also looked at what proportion of individuals were taking either over-the-counter pain management medications or prescription medication.
[12:39] About the migraine headache pain, most of it was over-the-counter use, although some reported prescription medication.
[12:54] Ryan grew up experiencing leg pain all the time. He attributed it to his other chronic disorders. It wasn’t until some years ago at an APFED conference that he heard a physician mention leg pain. Ryan had never considered it as an EoE symptom.
[13:38] One of the challenges the EGID Partners Registry has is that they don’t have enough individuals registered to start dividing the sample up further, by age. Roughly two-thirds of the respondents were adults.
[14:12] It’s also hard to get kids to report accurately what they are experiencing. It often comes down to the caregiver reporting it to the EGID Partners Registry, which brings its challenges.
[14:34] Ryan calls all patients listening to sign up with the EGID Partners Registry to allow the registry to get to some of these deeper questions.
[14:47] Dr. Jensen adds that people often want to understand why these pains are connected to EGIDs. EGID Partners Registry doesn’t know why.
[15:02] There are underlying biological processes that could potentially contribute to this observation of the increased prevalence of extraintestinal pain manifestations. In the EGID population, there is the enrichment of connective tissue disorders and more.
[15:36] There is also evidence that there are increased comorbidities associated with a more inflammatory milieu. That could contribute to these extraintestinal manifestations of pain.
[15:55] Dr. Jensen hopes to bring greater awareness to patients and providers, honoring what the patient is experiencing and digging a little deeper to understand what may be going on for this patient.
[16:17] EGID Partners Registry also did a study on vitamin deficiency and supplement use among patients with EGIDs. They looked at those who had been diagnosed with EoE alone and those who had another EGID, with or without EoE.
[16:47] In this study, unlike with the pain manifestation, they didn’t see a statistically significant difference between EoE alone and the other EGIDs. There was some higher proportion in those with the lower EGIDs, but it didn’t reach statistical significance.
[17:16] They saw a high proportion reporting physician-diagnosed vitamin deficiency, mainly Vitamin D and a few others. That suggests the need to screen patients for vitamin deficiency with a new diagnosis and when monitoring response to therapy.
[18:28] There are reasons why there could be vitamin deficiencies. You may have a restrictive diet or be avoiding certain foods because you know they are going to bother you, or for the lower EGIDs, it may be that you’re experiencing malabsorption.
[19:04] Holly plans to send this study to the people she is working with. She will ask them to read it, and then work to get a baseline.
[19:56] A patient could ask for this test from any provider. Dr. Jensen says if it helps them to bring the evidence from these papers, that’s great; she hopes this empowers patients when they talk with their providers about the care that makes sense for them.
[20:41] EGID Partners Registry compared those reporting a deficiency between those with EoE alone and those without EoE. Eighty-two percent of those with EoE reported a Vitamin D deficiency. About a fourth of each group reported a B12 deficiency.
[21:27] Iron was another deficiency reported by 55% in the EoE group and 69% in the Non-EoE EGID group. Vitamins D and B12, and Iron were the top deficiencies reported. Many of the respondents reported they were taking vitamins or dietary supplements.
[22:32] Dr. Jensen thinks a nice follow-up study to this would be to learn the proportion of respondents taking vitamin injections or infusions because of malabsorption issues with oral supplements.
[22:37] Dr. Jensen thinks this study likely reflects an under-ascertainment of vitamin deficiency. A lot of patients aren’t getting screened. We don’t have the data yet because it’s not a universal recommendation to screen for vitamin deficiencies.
[23:01] Dr. Jensen thinks awareness and increased screening will be key. Then we can start thinking about how we mitigate this.
[23:24] Patients did not report symptoms of vitamin deficiencies. Dr. Jensen thinks that’s another good follow-up question. She stresses that it’s important to screen for deficiencies whether or not symptoms of deficiencies are present.
[24:06] Holly considers her patients with various symptoms of vitamin deficiencies and wants to get on the website and ask questions. Dr. Jensen tells her there is a link on the registry site where you can suggest a question. She asks Holly to suggest a question!
[24:30] Patients were asked if they have ever had a vitamin deficiency and were also asked if they currently take vitamins or supplements. A vitamin pill is one type of supplement.
[25:10] The study also looked at the use of a variety of complementary and alternative medicine approaches that patients turn to because they’re not getting adequate relief from traditional approaches to addressing their conditions.
[25:34] They saw a higher proportion of individuals with non-EoE EGIDs reporting the use of these kinds of alternative treatment approaches. Roughly a fourth of non-EoE EGID patients reported the use of a chiropractor, vs. 10% of EoE patients.
[26:11] Roughly one-fourth of non-EoE EGID patients reported turning to different herbal approaches in trying to get some relief for their conditions.
[26:49] Dr. Jensen says as a researcher, whenever she does a study, she is led to more questions. All of the research so far has opened the door to many more questions, including questions about individuals who don’t have either EoE or another EGID.
[27:20] Dr, Jensen wonders, is this extraintestinal pain unique to those who have EoE and non-EoE EGIDs? How do we best mitigate this? What does the workup look like for the patient coming in with joint pain or leg pain?
[27:37] How can we understand the factors that contribute to this pain? How do we get providers thinking about screening for vitamin deficiencies so we have a better understanding of their prevalence in this patient population?
[28:04] If patients are not absorbing vitamins orally, How do we mitigate this? How do we optimize their nutrition so they are not dealing with vitamin deficiencies which can lead to other consequences down the road?
[28:24] The surprises are always, “What doors are getting opened as a result?” We’ve answered some questions but there are so many questions that we still need to answer.
[28:56] Ryan asks if a correlation was found in these studies between vitamin deficiencies and extraintestinal pain. He notices that missing his vitamins correlates with more leg pain. Dr. Jensen asks Ryan to go onto the website and pose that question!
[29:10] Dr. Jensen has not looked at the data in that way but she thinks it would be an interesting way to bring these two studies together and try to explain some of what they are observing.
[29:21] Holly thanks Dr. Jensen for sharing her expertise and this fascinating research to help all EGID patients have less painful and better quality lives.
[29:52] Dr. Jensen makes this request. “Please consider checking out the EGID Partners Registry website, joining, learning more about how you can contribute to this research, and introducing questions.”
[30:04] “We’re always looking for new questions and are excited to think about how we can partner with patients in addressing questions that matter to them. Help us continue to answer some of these critical questions.”
[30:32] One topic Dr Jensen is interested in researching is the implications for reproductive health for having these conditions. Some research in another data source suggests potential implications.
[30:54] EGID Partners Registry observed and reported this year that there may be some indication of a longer time to pregnancy and a lower proportion of EGID patients experiencing a pregnancy. They want to look at that and understand it better.
[31:12] They want to understand it with more detail than they can get from the administrative data source with the initial questionnaire. EGID Partners Registry is pushing out a reproductive health history questionnaire now.
[31:29] EGID Partners Registry needs individuals to join and respond to the reproductive health questionnaire to help them understand this more deeply and some of the findings they are seeing initially in some of these other data sources.

[1:38] It was a nice surprise for Ryan. Beth, one of the founders, gave a lovely speech about Ryan and Zach, the other award recipient. Ryan has known Zach for 20-plus years and they are life-long friends. They’ve known Beth for just as long. It was perfect.
[2:23] Ryan’s highlights of this year’s conference were going down memory lane looking at the photos in the award presentation, meeting a lot of new patients and families, talking about experiences, and speaking with the wonderful researchers and speakers.
[3:13] Mary Jo appreciated how the speakers delivered their messages in a way that was easy to understand. It was great to have them involved in the conference.
[3:27] Mary Jo found it interesting when Dr. Spergel said on Friday that EoE may not be considered a rare disease for much longer and he raised the question: Is prevalence rising or are more people being diagnosed from better awareness around EoE?
[3:57] Ryan also says it’s interesting to hear. APFED doesn’t want to be necessary. Ideally, everyone can see their pediatrician, get the diagnosis early, and get treatment early, not only for EoE but for everything else.
[4:16] So many children come to APFED now, diagnosed early and on treatment options. On the adult side, so many people are coming to APFED saying they’ve lived with symptoms for years, not knowing what it was, and now have a diagnosis.
[4:51] While EoE is becoming more common, there are the rarer eosinophilic subsets to talk about, HES (hypereosinophilic syndrome), eosinophilic fasciitis, and EGPA (eosinophilic granulomatosis with polyangiitis).
[5:50] Dr. Amy Klion joined the conference virtually but attended the reception onsite. She is crucial to some of the rare eosinophilic disease research projects.
[5:59] Mary Jo found Friday’s conversation with Drs. Sauer and McGowan about the management of EoE patients to be intriguing, in particular, when it was recognized that the GI and allergist might not always agree on approaches to treatment.
[6:09] There was a lot of excitement around less-invasive diagnosistics. Mary Jo says it was fun to see the videos of Drs. Sauer and McGowan trying the string test.
[6:25] Ryan has not yet tried the string test. It was fun for him to see that video of the two doctors trying it. The two doctors also shared their experience trying a six-food elimination diet. It was wonderful to have both doctors at the conference.
[6:47] Holly Knotowicz could not join the podcast today but she and Ryan have talked before on the podcast about the importance of multidisciplinary care teams and how crucial they can be.
[6:57] It was wonderful to hear from the doctors that they are working on multidisciplinary care teams on the pediatric side, through the transition process, and onto the adult side. Ryan hopes they can create a roadmap for other facilities to follow.
[7:13] In the string test, the doctors both gagged at the end, but they made it through and both said their patients do a better job going through it with a straight face! The string test is now available at multiple U.S. sites.
[7:42] For Mary Jo, it was fun to see so many kids and teens on site enjoying themselves in the activities and the mentorship they were having. A robotics team came on site. There was a fun Family Feud-style game.
[8:11] Ryan says the activities were absolutely crucial for him growing up. It was one of his favorite parts of the conference, coming back year after year, being with his friends again in an environment where he was able to feel so normal and among peers.
[8:29] Ryan says you can lead a pretty normal life with EoE or other eosinophilic disorders, but it’s not something your school peers can relate to. Coming to the conference is so impactful. Ryan heard multiple kids say, “Wow, you’re just like me!”
[8:46] For Ryan, it’s amazing that the conference can offer that environment for everybody. Ryan says it’s wonderful to have the teen program with so many volunteers to help. Ryan met Zach in a kids and teen program and now he helps run them.
[9:13] Many incredible volunteers came to help; Ryan mentions some by name. It’s wonderful that the conferences have been able to create such a tight-knit community for these patients.
[9:24] Mary Jo appreciated the volunteers doing the kids and teen programming this year for the conference and Amelia coming on-site as well.
[9:38] Mary Jo liked the talk on coping with chronic illness and Dr. Kichline’s advice that you may not be able to change the situation but you can change how you react to it. It’s important for children to learn and adults to remember; you are not your disease.
[10:06] Ryan remembers that point being emphasized when he was young. Thanks to APFED, we have a mentality here that you’re a kid first and then you also have to deal with allergies, medicines, and doctors’ appointments.
[10:18] We want to make sure that you can enjoy school, enjoy your childhood, go out, hang out with friends, and be who you want to be without having to have EoE at the forefront of your identity.
[10:32] That goes for all the other eosinophilic disorders and into adulthood. Those who were diagnosed 20 years ago are entering the workplace and figuring out how to be an adult with EoE. We have our lives first and part of that is managing this chronic illness.
[10:55] Ryan says it was wonderful that they were able to talk to the disability lawyer. Part of the management of chronic illness is making sure that you can be an adult or a kid and have financial support through something like SSI or employer-based disability.
[11:20] Mary Jo comments on the terrific presentations on the virtual day. It was great to hear from Dr. Fussner about EGPA. That tied in well with the new EGPA Toolkit that APFED launched this week in collaboration with the Vasculitis Foundation.
[11:47] You can find the new EGPA Toolkit at APFED.org.
[11:59] Ryan thinks it’s exciting that the conference highlighted some of the more rare eosinophilic disease subsets. On the virtual day, presenters talked about EGPA, HES, eosinophilic asthma, and eosinophilic fasciitis.
[12:12] Eosinophilic fasciitis is so rare. Two people were chatting in private messages beside a presentation that they had never talked to someone else with eosinophilic fasciitis. Ryan also saw there were multiple HES patients in person this year.
[12:30] Ryan states that it is exciting to see patients even with these rare disease subsets being able to come together and hear about the latest research.
[12:37] Mary Jo answers that’s why we call it EOS Connection! Ryan agrees; we’re making those patient connections even among these rare subsets.
[12:47] Mary Jo had a fantastic time at the conference. She learned a lot and she hopes Ryan and everybody watching did, as well.
[12:57] If you did not participate in the live events, Mary Jo and Ryan encourage you to visit APFED.org/conference and register to access the virtual conference to watch the recordings and explore the virtual poster hall and exhibit hall, through the end of 2024.
[13:21] Ryan thanks our education partners for supporting this event. It was wonderful to have so many people here; he hopes everyone was able to enjoy the virtual event.
“It was so wonderful to hear from doctors working on multidisciplinary care teams on the pediatric side, through the whole transition process, and onto the adult side. I hope they can create a roadmap for other facilities.” — Ryan Piansky
“It was fun to see so many kids and teens on site enjoying themselves in the activities and the mentorship they were having.” — Mary Jo Strobel
“We have the new EGPA toolkit resource that we launched this week in collaboration with the Vasculitis Foundation. You can find that resource on APFED.org.” — Mary Jo Strobel
“It’s exciting that we were able to highlight some of these more rare disease subsets. In the virtual format, where we’re able to reach so many more people, we talked about EGPA, HES, eosinophilic asthma, and even eosinophilic fasciitis.” — Ryan Piansky
[2:01] Dr. Ketchem did his residency at the University of Pennsylvania following medical school. There he met Dr. Evan Dellon, a world expert in EoE. Dr. Dellon became a mentor to Dr. Ketchem.
[2:24] As Dr. Ketchem learned more about EoE, he was fascinated by the many unknowns and opportunities for discovery within the eosinophilic GI field. He wanted to make an impact on patient care.
[2:51] Under Dr. Dellon’s mentorship, he did epidemiologic studies. Seeking specialized training, he ended up at the University of Pennsylvania where he is getting rigorous training in epidemiology to study EGIDs.
[3:18] As ChatGPT was gaining its buzz, Dr. Ketchem saw a lot of clinical applicability. He views AI as an asset in epidemiology and hopes to use it to accelerate his research.
[4:30] AI usually references using computers to mimic human abilities, estimate decisions, or predict outcomes. An example is Natural Language Processing (NLP), to analyze and understand human language. Large Language Models (LLM) use NLP.
[5:08] ChatGPT is based on a LLM. LLMs use NLP techniques to understand vast amounts of text that they are trained on and generate responses in a chat format.
[5:25] Machine learning is another subset of AI that uses statistical techniques to give computers the ability to learn with the data and predict outcomes.
[5:50] The hope is to use these AI techniques to speed up discovery and also minimize human expense or labor.
[6:28] Dr. Ketchem co-authored a paper in Clinical Gastroenterology and Hepatology about an AI chatbot and EoE. He had been inspired by a cardiology paper on whether ChatGPT would create accurate, appropriate answers about cardiology disease health.
[7:19] Dr. Ketchem wondered if ChatGPT could be applied to EoE education. He discussed it with Dr. Dellon and Dr. Krystle Lynch, Dr. Ketchem’s mentor at the University of Pennsylvania, and with Dr. Joy Chang, at the University of Michigan. They came up with a study design.
[8:06] The study asked ChatGPT questions about EoE, focusing on patient education and the therapeutics, and seeing if it gave accurate responses or not.
[8:45] The four doctors developed 40 questions that they gave ChatGPT as prompts and evaluated the responses. They proposed the questions in two ways: each question in an individual chat and 40 questions in a single chat.
[9:41] Analyzing the responses, the study demonstrated that ChatGPT responded with multiple inaccuracies to questions about EoE on general topics, complications, and management. Over half of the responses mixed correct and incorrect information.
[10:09] To evaluate the readability of the responses, the doctors used the Flesch-Kincaid reading ease tool. To understand the output from ChatGPT one would need high school and two years of college. That poses a potential health literacy barrier.
[11:40] The questions ranged from general: “What is eosinophilic esophagitis?”, to complications: “What is a food impaction?”, “What is a stricture?”, to therapeutics: “What are steroids for eosinophilic esophagitis?”, “Can I use a proton pump inhibitor for EoE?”
[12:15] It was not clear where ChatGPT pulled data from to respond to the questions. The data it was trained on was known to be in texts over a year old. Newer data may not have been accessible to ChatGPT.
[13:29] The doctors asked about things that were common knowledge in the eosinophilic GI realm, like dupilumab, and ChatGPT didn’t know much about it because it was a newer treatment option for EoE at the time of the study.
[13:42] The doctors scored the answers on their scientific accuracy and patient educational value. Simple questions got good responses. For questions about therapies and complications, “it wasn’t doing well.” They identified limitations to the study.
[14:14] The doctors asked ChatGPT if EoE is associated with cancer. From their best epidemiologic knowledge, the doctors don’t think that it is. ChatGPT falsely associated EoE with esophageal adenocarcinoma.
[14:34] ChatGPT also associated EoE with Barrett’s esophagus. To the doctors’ best epidemiologic data, they are not sure that there’s a connection.
[15:02] When the doctors asked the questions in individual chats, they asked ChatGPT for medical literature references for the information. It didn’t provide accurate references. Titles and authors were often incorrect and links often didn’t work.
[15:36] The incorrect references were a signal that ChatGPT wasn’t ready to answer complex medical questions. In the more updated versions of ChatGPT, instead of giving references, it says you should consult your doctor, which is the right thing to do.
[15:56] The researchers concluded that implementing this technology requires clinical oversight; it’s a tool that should be used with caution for patients in educating themselves and also from the perspective of a physician who is not an expert in EoE.
[16:29] Dr. Ketchem had been surprised by how long the responses were. He was expecting paragraphs but got pages and pages. He was also surprised by how quickly people were starting to use ChatGPT in other aspects of gastroenterology.
[16:57] While Dr. Ketchem and his team were writing the paper, another study came out about gastroesophageal reflux (GERD) that was somewhat similar to what Dr. Ketchem proposed for EoE. There is rapidly much being published about ChatGPT.
[17:14] Although the results were imperfect, there is potential applicability in patient-facing chats in the future for patient education but not yet there “for prime time.”
[18:33] These chats need to be transparent about where they’re getting data, especially in the medical field.
[18:41] There will always be a role for people in medicine. You can't replace a face-to-face connection with a nurse or a physician with a chat bot.
[19:11] Dr. Ketchem says everyone needs to be careful about using AI tools. He advises patients to always discuss any medical questions with their physician. AI tools are not yet able to provide accurate medical information all the time.
[19:50] Ryan reminds listeners that this podcast is for educational purposes. Always consult your physician before making any changes to your healthcare. If you ask ChatGPT, also consult with your doctor before making any changes to your healthcare.
[20:31] One of the problems with large language models is the potential for inaccuracy. Dr. Ketchem’s gold standard is the medical literature and you don’t know where the large language models are getting their information.
[21:04] Future benefits may include helping patients get answers quicker and becoming more educated. Dr. Ketchem hopes we will get to a point where we can trust these technologies and implement them safely.
[21:37] Government organizations like the National Institutes of Health (NIH) and the U.S. Food & Drug Administration (FDA) are bringing together experts to think about large language models and create regulatory frameworks for their use in healthcare. Dr. Ketchem tells how HIPAA (Health Insurance Portability and Accountability Act) rules are followed to protect patients.
[23:29] Dr. Ketchem sees potential in machine learning to predict which therapies an EoE patient will respond to. AI is also used in colonoscopies to identify hard-to-see polyps. It might be useful in endoscopies to see changes in the esophagus from EoE.
[24:35] AI image recognition could also be applied in pathology. Dr. Ketchem is interested in trying to apply it to work he wants to do in the long term. People are working with pathology specimens to automate the counting of eosinophils. Dr. Ketchem discusses the potential use of AI for epidemiology in pathology.
[25:43] Dr. Ketchem and Holly discuss the potential for using AI chatbots in medical screening questionnaires. There will always need to be a human element.
[27:57] Dr Ketchem speaks to the potential future development of educational videos prepared by AI. It is a complex scenario that would require a lot of training. If a camera is added, AI could analyze where patients are having problems in taking medications.
[29:55] Dr. Ketchem says there are many moving parts in healthcare and many stakeholders, making it difficult to implement AI. It could be used in many aspects, but its use must be safe. Dr. Ketchem thinks it will soon be useful in medical imaging.
[30:57] In the next decade, AI may be used in drug discovery, clinical decision-making, and healthcare administrative operations. The goal is to improve the care for the patient. Personalized care would be an aspirational goal of using artificial intelligence.
[31:29] Dr. Ketchem heard of a computer scientist at a government meeting suggesting a far-future scenario of doctors having digital versions of patients to test the patient’s reaction to a specific medication, based on comorbidities and other medications in use.
[32:30] Holly thanks Dr. Ketchem for sharing his research findings to help others.
[32:40] Dr. Ketchem’s last words: “The future is bright. There are many open avenues to apply these technologies to eosinophilic GI diseases – in diagnostic support, personalizing treatment, and predictive modeling – to make patient care better.”
[33:10] Dr Ketchem is building a research program to use epidemiologic training with artificial intelligence. He hopes to find how to take text from histology or pathology and apply epidemiologic methods, to build a cohort of patients to study diseases faster.
[34:03] Dr. Ketchem hopes to use AI to help predict patient outcomes, regarding who will respond to what therapy and who will have more complications from their disease; those are things he is interested in. There are so many unanswered questions.
[34:30] After Dr. Ketchem finishes his fellowship, he hopes to be an independent investigator, being curious and answering these questions somewhere. If you know of such a job, please let Dr. Ketchem know!

Bio:
Dr. Corey J. Ketchem, MD is a rising third-year gastroenterology fellow at the University of Pennsylvania, driven by a profound interest in allergic inflammation of the gastrointestinal tract, particularly eosinophilic gastrointestinal diseases (EGIDs). He has acquired a unique skillset in clinical epidemiology and biostatistics that equip him with the necessary tools to conduct rigorous research studies, culminating in a Master of Science in Clinical Epidemiology (MSCE) upon fellowship completion. Dr. Ketchem's passion for EGIDs has spurred a series of epidemiologic investigations focusing on both eosinophilic esophagitis (EoE) and non-esophageal EGIDs, yielding numerous publications in high-quality gastroenterology journals and earning him recognition through various research awards. Moreover, his academic path has included the incorporation of artificial intelligence into his research endeavors, aiming to enhance patient care and facilitate epidemiologic studies. Dr. Ketchem's trajectory is set toward becoming an independent researcher, dedicated to employing high-quality epidemiologic approaches to uncover pivotal insights into EGIDs, advance clinical knowledge, and optimize therapeutic strategies for patients.
[1:53] Dr. Gonsalves’s extensive clinical experiences with EGIDs have shaped her research goals, which include identifying novel treatments and determining the best methods to measure disease activity.
[2:20] Dr. Nirmala Gonsalves has been at Northwestern for 25 years and has been involved in the EGID and EoE space for the last 20 years. Dr. Gonsalves met Ryan during her first introduction to APFED when Ryan was “much, much younger,” so she is pleased to see him co-hosting this podcast.
[2:56] Within Northwestern Medicine, Dr. Gonsalves is part of the Esophageal Group. Within the Esophageal Group, she co-directs the Eosinophilic GI Disorders Program with Dr. Ikuo Hirano. Working in the EGID space for the last 20 years has been incredibly rewarding.
[3:11] Dr. Gonsalves feels lucky to be a part of The International Gastrointestinal Eosinophil Researchers (TIGERS) and the Consortium of Eosinophilic and Gastrointestinal Disease Researchers (CEGIR).
[3:26] Dr. Gonsalves has focused her clinical career on understanding eosinophilic GI disorders, helping to get better diagnoses, increased awareness, and better treatments, and improving the quality of life for patients with these conditions.
[4:19] Dr. Gonsalves describes the study of food-induced immediate response in eosinophilic esophagitis (FIRE). In 2017, gastroenterologist Dr. Alex Straumann, and allergist Dr. Mark Holbreich, both very familiar with EGID, started a multi-center effort and project, working with many physicians and patients to define this condition of FIRE.
[4:45] The symptoms of FIRE are very different from what we typically think about as EoE symptoms. The classic symptoms of EoE in adults are dysphagia (difficulty swallowing), or food impaction (a bolus of food stuck in the esophagus).
[5:37] This team of researchers in Switzerland, Northwestern, Indiana, North Carolina, Colorado, and Mt. Sinai, to name a few centers, noticed patients describing different symptoms; a more immediate response that was happening in their esophagus when they were exposed to certain specific foods, like beer or wine and avocado or banana.
[6:19] Patients described an immediate reaction in their esophagus, occurring any time from seconds to minutes after ingesting that food, as a painful, squeezing sensation, and a narrowing in their esophagus that was temporally related to these foods.
[6:42] It started to increase the researchers' awareness that this symptom was different from the classic dysphagia that adults and older children typically present with.
[7:12] In the study, they did a two-phased investigation. First, they sent a survey to physicians used to treating EoE, to understand what their experience was about these symptoms. Based on that knowledge, they convened twice to develop a questionnaire for patients, to understand how common this is in the patient population.
[7:38] The response was 47 physicians (an 82% response rate). They sent the patient survey to the EoE Swiss cohort and the response was 239 patients (a 65% response rate.)
[7:58] Of the physicians, 90% reported patients reporting these symptoms. The physicians estimated this to occur in 5 to 20% of EoE patients. Looking at the patients who had FIRE with EoE, vs. EoE without FIRE, the FIRE patients were younger and more likely to have other atopic conditions like rhinitis, asthma, and dermatitis.
[8:42] Patients with FIRE were more likely to have had a prior food impaction, a longer duration of disease, and a longer time to symptom presentation. Those were the risk factors in the patients.
[8:56] In the patient questionnaire, 40% of the EoE patients surveyed reported that they had symptoms of FIRE.
[9:29] Most of the patients in the study were adult patients. Looking at the average age of the EoE cohort vs. the EoE with FIRE cohort, the EoE with FIRE patients tended to be younger. Dr. Gonsalves suspects that patients are experiencing FIRE earlier on, but they don’t know what is occurring.
[9:56] Dr. Gonsalves thinks that is where the investigation is going: to understand when FIRE is happening. The symptoms are quite different than the typical first EoE symptom when something is going down slower or getting caught in the esophagus.
[10:27] As far as whether FIRE is experienced by other patients besides EoE patients, the survey team only noticed FIRE in EoE patients. A follow-up study could look at the control cohort or the regular reflux cohort. Patients don’t express these types of symptoms, other than EoE patients, so it seems unique to EoE patients.
[10:53] When the team talked about and tried to understand more about the background of FIRE, and the risk factors, they wondered if it was similar to oral pollen syndrome, with a more immediate reaction in the esophagus.
[11:49] With adults, certain liquors, wines, beers, avocados, and bananas stand out among triggers. The symptoms are so significant that patients would say on a scale of one to ten, it’s a seven intensity. It’s fairly immediate, within seconds to minutes, with a duration of minutes to several hours.
[12:18] A lot of times, patients compensate by not eating those specific foods because they don’t want that condition to happen. For some patients, it’s a profound spasm-type squeezing in their chest that will occur when this happens.
[13:44] Dr. Gonsalves says many patients will confuse FIRE with an anaphylactic reaction; it’s not clear what it is. The multidisciplinary group of physicians that worked on this study included allergists and gastroenterologists all tried to come up with the mechanism that causes FIRE. It does not appear to be an anaphylactic reaction.
[14:13] When FIRE occurs, the doctors of the multidisciplinary group ask their patients to seek care from their allergist and discuss this with their allergist, to get more testing and understanding of what’s occurring. They want to be mindful if there’s any risk of anaphylaxis, but it does not appear that the FIRE condition is related to anaphylaxis.
[14:55] Dr. Gonsalves says we’re at the very early stages of understanding the mechanisms of why FIRE is occurring. The first step was to increase awareness, define FIRE, understand it, and separate it from both EoE symptoms and anaphylaxis. We don’t yet understand the mechanisms.
[15:18] At Northwestern, they are looking at a study to define FIRE better. They look to see if there is IgE sensitivity to these foods. If there are not, they look to see if there are any nanometric changes in the esophagus when these foods are in the esophagus. Are people having the esophageal spasms that equate to the symptoms they describe?
[16:03] That study is to understand more about the mechanisms causing FIRE. What happens to the FIRE symptoms? Once a physician treats a patient with EoE, the FIRE gets better. Patients sometimes can reintroduce the foods when their EoE is quiet. There is a short window of time to identify FIRE in a patient before treatment.
[16:43] Early identification and early treatment is the mantra. They don’t want to delay treatment in any patient. When the EoE goes in remission from treatment, the FIRE symptoms tend to go into remission, also.
[17:01] This is unpublished data and research they are working on. Hopefully, they will learn more and be able to share it with APFED. These are their speculations.
[18:17] At Northwestern, they are known for dietary therapy. Their patients gravitate toward diet therapy. The foods involved in FIRE symptoms are not big EoE triggers. In dietary therapy, when foods are reintroduced, patients describe recurrent dysphagia, heartburn, and EoE-type symptoms.
[18:56] Patients having foods reintroduced don’t typically describe this immediate reaction where their esophagus is spasming, contracting, and feeling very tight right after. That’s a very different symptom.
[19:17] For the patients studied, the foods most consistently triggering FIRE symptoms were fruits, wines, vegetables, honey, beers, and vinegar. The foods driving FIRE tend to be the foods driving oral allergy but the symptoms are different; no mouth, tongue, or lip itching, but a squeezing sensation in the esophagus.
[20:29] Dr. Gonsalves says they have not identified long-term consequences of FIRE. They are very early in the stages of understanding and following it. The long-term consequences come from untreated EoE. Dr. Gonsalves lists some consequences of untreated EoE, including worsening scarring, strictures, and dysphagia.
[21:08] Dr. Gonsalves speculates and wonders if physicians were sometimes confused between dysphagia, oral-pollen allergy symptoms, and FIRE symptoms, without it being clear what the patient was experiencing, leading to a delay in diagnosis.
[21:52] Dr. Gonsalves says having patients with FIRE symptoms highlights the importance of having a multidisciplinary program and having a good collaboration with allergists, dieticians, and GI health psychologists to address food fear and anxiety, pathologists, and pediatricians. It’s important to have conversations with colleagues.
[22:31] Dr. Gonsalves says there’s no test for FIRE, which is why we’re doing this research project; understanding what is behind FIRE, now that we know FIRE exists, we have a description, and we know how prevalent it is. We need to look at the patient and look for contractions of the esophagus upon exposure to the food with manometry.
[23:18] Manometry is a tube with pressure sensors used for measuring esophageal pressure and the strength of contractions. Patients with EoE have various abnormalities in their esophageal contractions. To study FIRE, with the manometry tube in place, the patient will eat the trigger food or drink to see if there are heightened contractions.
[25:24] Manometry is not an easy test. It is done when necessary to understand esophageal motility and function. It’s not easy to recruit for these tests and there are not many candidates as the symptoms go away quickly with treatment. The technicians are skilled in doing the testing. It’s done routinely and safely.
[26:47] Dietary, pharmacological, steroidal, and biological treatments can be effective in treating EoE symptoms. When EoE symptoms stop, FIRE typically stops. There has not been a study to document this, but it has been observed clinically. After a patient has been treated and then is tested for esophageal motility, FIRE does not typically recur.
[28:05] Dr. Gonsalves shares her suspicion that there is something related to esophageal inflammation that triggers this type of response and a hypercontractile state in that setting. Ryan reminds listeners that this podcast is not medical advice; always consult with your physician before making any changes or trying new treatment options.
[29:40] When a provider talks to a patient, they might ask about dysphagia if they are making modifications for swallowing, and how they swallow something dry or dense. Can they perceive it going slowly down their esophagus? Are they taking in lots of liquid to help this food pass? Are they chewing excessively? Are they avoiding foods or pills?
[30:40] These questions help providers understand if there is disease activity and if they are not symptomatic because of avoiding these types of foods. Those are EoE questions.
[30:52] Asking about FIRE symptoms or oral pollen allergy symptoms, the provider will go down a list of allergic history questions about allergic rhinitis, asthma, eczema, and anaphylactic symptoms. Also, mouth itching, lip-tingling, or throat itching when they eat certain foods.
[31:20] After they eat these foods, do they ever experience an immediate sensation of narrowing or tightening or spasm in the esophagus, or burning pain that happens secondary to the dysphagia? The important thing is to separate the transit dysphagia of things moving slower down the esophagus from this perception of squeezing pain.
[32:18] Holly thanks Dr. Gonsalves for sharing her expertise to help others.
[32:37] Dr. Gonsalves’s last word is that this condition exists. Providers, ask your patients about them. It was remarkable to Dr. Gonsalves how profound the symptoms were that patients described to the point where they avoided these foods and were scared of these foods.
[32:56] Interestingly, FIRE is very different from EoE symptoms. It does exist. Ask about it! That will help tease out the reactions that are occurring. Especially, understand that when going on a food elimination diet, these are separate from the EoE triggers.
[33:18] If you identify these symptoms, or oral pollen symptoms, or coexisting atopic conditions, partner with an allergist so that we understand the mechanisms behind this and make sure that nobody is at risk for anaphylaxis from these types of things.
[33:49] Dr. Gonsalves is pleased to partner with TIGERS and to be on a site for the CEGIR Group. Dr. Gonsalves heads up the development of the Non-EoE Consensus Guidelines, to understand what goes into a diagnosis of Non-EoE EGID and what that entails. She continues to research dietary therapy and making it better for patients.
[34:31] She works to understand different metrics to measure activity in the esophagus, histologically as well as motility-based, and the genetic changes that occur with different treatments, and doing all this, partnered with an amazing group of collaborators through the CEGIR Consortium and others to improve patients’ quality of life.
[35:01] Dr. Gonsalves feels lucky that 20-something years ago, she bumped into the leaders of APFED and other patient advocacy groups and shared their experience with Northwestern. She is grateful for the privilege of working with all the wonderful physicians and patients who help us learn about these conditions.

“Working in the EGID space for the last 20 years; it’s been incredibly rewarding. I’ve been lucky enough to be invited to be a part of The International Gastrointestinal Eosinophil Researchers (TIGERS).” — Nirmala Gonsalves, M.D.
“Our patients will describe it; it’s a profound spasm-type squeezing in their chest that will occur when FIRE happens.” — Nirmala Gonsalves, M.D.
“There’s no clear test yet for FIRE, which is why we’re doing this research project; really understanding what is behind FIRE, now that we know FIRE exists, we have a description of it and we know how prevalent it is.” — Nirmala Gonsalves, M.D.

Dr. Gonsalves is a Professor of Medicine in the Division of Gastroenterology & Hepatology at Northwestern University Feinberg School of Medicine and Co-Director of the Northwestern Eosinophilic Gastrointestinal Disorders Program. She completed her undergraduate training at the University of Notre Dame, medical school at Robert Wood Johnson Medical School in New Jersey, and her internship, residency, and fellowship at Northwestern, where she has stayed on as an attending physician since 2005. In this role, she has co-authored more than 60 manuscripts and presented at more than 40 national or international meetings that focus on eosinophilic gastrointestinal diseases (EGIDs). Her research and clinical career is dedicated to improving the care of patients with these rare disorders. Her extensive clinical experiences with EGIDs have shaped the overarching research goals that include identifying novel treatments and determining the best methods to measure disease activity. She is a site investigator for the NIH-funded U54 Grant Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR, PI-Rothenberg) and Core Lead for the Northwestern Biorepository for an NIH sponsored PPG Grant on Esophageal Biomechanics (PI-Pandolfino).
[2:46] Holly shared how Christine Miserandino developed the Spoon Theory while at brunch with a friend. Her friend asked Christine how she was coping living with lupus. Christine grabbed all the spoons from the table and explained that each task throughout the day costs a spoon.
[3:21] Christine asked her friend to walk through every activity of her morning. As her friend started talking about the different things she does, Christine would remove a spoon from her pile of 12 spoons. When dinnertime came, there was only one spoon. That limited her choices for dinner; this was long before dinner delivery services.
[4:19] Through this exercise, Christine’s friend learned how chronic illnesses use up a lot of energy just from existing. For listeners who want to read more, please check out Christines’ website, ButYouDontLookSick.com, linked in the show notes.
[4:33] Ryan sees the Spoon Theory as an easy way to convey what living with a chronic illness is like. He asks, why is it 12 spoons? Does everyone have the same number of spoons? In interviews, Christine has said 12 was the number of spoons on the table but it is a good representation of the limited supply people with chronic illnesses have.
[5:07] According to the theory, healthy people have an “unlimited” supply of spoons, while people with chronic illnesses have to ration their spoons to get through the day. Everybody’s number is slightly different but the theory uses 12.
[5:22] Ryan shared a story about seeing his sister during the holidays. She doesn’t have a chronic illness. She seems to have unlimited spoons for activities she plans, while Ryan may run out of spoons around 10:00 a.m.
[5:46] Ryan asks if it is always the same number of spoons per day. Holly says your baseline number is about 12 spoons. It can vary if you borrowed spoons from the day before or if you have spoons left over from the day before. Some say on a good day, you might wake up with 20 spoons but a bad day would start with 12 spoons.
[6:34] Holly explains about borrowing spoons. If you run out of spoons on one day, before you finish your activities, you might borrow spoons from the next day by canceling a planned activity for the next day. Holly also explains it to people as a lending library.
[7:49] When Ryan was young, he attended the APFED patient education conference every year. He recommends it. His parents warned him not to overextend himself but to take it easy and rest during the day. At every conference, he just kept going for 12-plus hours. When he got home, he would crash for a day. He had used up all his spoons!
[8:36] Ryan asks what happens when you run out of spoons. Holly shares that when you run out of spoons, your body might have a flare-up, or be more susceptible to getting sick because you’ve become rundown.
[9:10] It can also lead to comparison with others and feeling sad or anxious because you don’t have the energy that healthy people around you have. For the average person with chronic illness, cooking from scratch from a recipe could be three or four spoons.
[9:51] For someone with a specialized diet, that could double. You’re not just reading the recipe, you have to think about substitutions and go buy them. You have to know if the recipe will taste good with substitutions. It’s mentally exhausting to follow recipes for specialized diets.
[11:04] Holly is an extrovert but sometimes being with people can take too many of her spoons, so she carefully plans her socializing. Being with good friends might take three spoons. Presenting at a conference takes more spoons. Walking a dog could take two spoons. Taking medication or brushing her teeth could take one spoon.
[12:10] For children with chronic illness, going to school might take four of their spoons. Playing soccer might take five spoons, so at times they don’t have the energy. This can result in absences from school because they want to have typical social lives but don’t have the energy and reserves to do so. It’s the same for adults but it’s a hard fact for children.
[12:53] Ryan was diagnosed with EoE at age two. Ryan thinks back to high school. He woke up at 6:15 every day to get to high school before 8:00. Getting to school on time probably took most of his spoons. The rest of the day was exhausting. He never did any extracurriculars in high school. By 3:00, he was down for the count.
[13:50] If Ryan’s friends wanted to spontaneously do something after school, he often had to refuse. He needed a few days to prepare physically and mentally for extra activities. Having something sprung on him at the last minute drained more of his spoons. He would like to have had the Spoon Theory to explain it to his friends.
[14:52] Holly says there is a mental aspect to having a chronic illness. You have to think about things in advance, especially people living with eosinophilic diseases and/or those who have specialized diets. To consider going out to a meal, you might have to research a restaurant in advance or even talk to the chef. Thinking about and making these phone calls requires spoons.
[16:06] Recently Ryan planned to go out with friends. After they picked a restaurant and Ryan chose what he would order, the friends decided to try a different restaurant. Ryan had to check the menus of six other restaurants before they settled on the original one. The extra effort depleted Ryan’s energy and he just sat quietly during dinner.
[19:14] Ryan didn’t push himself to be social because it would have eaten into his reserve spoons for the following day. As it was, he slept in the next day.
[20:07] Ryan has had days where he has had to use up the next day’s spoons, and then had the next day be equally busy.
[20:28] The Spoon Theory can be applied to different chronic illnesses. Most of them are invisible illnesses. It makes sense that Christine’s website is named ButYouDontLookSick.com.
[21:29] Holly loves that the Spoon Theory provides a visual representation of how our energy works and how we can manage it. Because many chronic illnesses are invisible, people don’t always understand why we have to cancel, abort, or decline plans. We often have to prioritize activities to protect our health. It’s a different standard.
[22:10] We prioritize activities to protect our health and how we feel. Holly uses the Spoon Theory to explain why she declines plans in advance when she has too many things scheduled. She wouldn’t be her best self. Holly rarely schedules anything for after an eight-hour workday.
[22:55] Holly thinks of herself as a dynamic person who brings a lot to the table. She doesn’t want to be in an activity where she can’t participate fully. It reflects on how much her diagnosis seeps into her life. She doesn’t like to share her EoE with everybody, even though many people in her life know it and she does this podcast!
[23:25] Over the last six months, Holly’s goal has been to map out her week to keep her energy consistent. She plans when to work out in the morning, when to see patients, and when to fly for international conferences. She gives herself a rest day after the flight or she stumbles and mumbles during the presentation. This means she often declines dinner invitations.
[24:45] Holly will accept invitations to destination weddings but then will not book anything extra for a week afterward or she knows she will get sick. It’s a pattern.
[25:28] Ryan says sometimes people can tell when he’s not at his best, but for the most part, he looks relatively healthy. He’s up and about, at meetings and conferences but it’s such a limited amount of energy that he has available. It’s hard for people with unlimited spoons to gauge how many spoons Ryan has left.
[25:57] Holly often presents at medical conferences about feeding therapy, eosinophilic diseases, food allergies, FPIES, and tube feeding, and she incorporates the Spoon Theory into some of her talks. She has spoons at the podium and starts dropping them as she goes, holding one or none by the end. That’s when questions come.
[27:25] Holly likes people to know that when they’re working with kids with chronic illness, it’s important to pace out their therapy. For example, give a patient two things to work on until the next time, not ten, to be successful.
[28:50] Ryan clusters his multiple specialist annual visits at the start of the fall semester and at the beginning of the spring semester. That means he misses some classes and lectures at the beginning of each semester. It is draining. Tests eat up half his spoons for the day.
[30:35] Holly shares how applying the Spoon Theory impacts managing her health. The Spoon Theory helps her create and maintain boundaries. She adamantly tries to stick to a schedule that rarely depletes her spoons per day. It’s still a work in progress. Holly has a therapist who is helping her work on it.
[31:08] Holly schedules social things on days when she has little to no other obligations. She has to maintain that schedule. She has good days and sometimes great weeks which leads her to add more to her plate, but then she runs out of spoons more quickly because she’s borrowing from the next day. Eventually, she has no spoons to borrow.
[31:42] Holly went on vacation for her birthday and then last week she was doing great, taking some urgent referrals for babies. This week, she had to cancel things. She is learning that she needs to schedule time to recharge and rest even on good days.
[32:26] Holly has learned there are ways to increase your number of spoons. The most important things are to be compliant with treatment and follow a specific diet (if recommended). A lot of chronic illnesses have a specific researched diet to help you stay healthy. When you have a cheat day, you’re harming yourself by taking spoons from your next day.
[33:31] Working out helps with anxiety and depression. There are physical and mental health benefits. Holly started tracking over the last eight months how many spoons working out earned for her, compared to the spoon it took from her. She finds that it adds three to five spoons to her daily reserve. The endorphins boost her energy.
[34:14] Ryan agrees. He goes to the gym at least twice a week. If he misses a day, he feels worse. He goes out for a walk on days he’s not going to the gym just to get moving and he feels better after that. Being stuck inside all day is mentally draining as well. Going for a walk takes extra effort but it does feel better.
[35:32] Ryan and his mother have similar food allergy issues so they both carefully stick to their diet. If they vary their diets on vacation, even without eating triggers or allergens, they feel physically bad for a few days until they get back to their usual diets.
[36:28] Once Holly learned about this theory and was making new contracts, she realized that there may be times when she might have to cancel and reschedule. When she sends an email about an engagement, she includes an article on the Spoon Theory and describes what she is struggling with, in case she has to reschedule.
[37:42] The Spoon Theory is a good way to describe to friends or family why the person with the chronic illness isn’t hosting the holiday but may need to go to a room and rest at the host’s home. It’s a tool to inform loved ones and friends so they can be supportive. It’s a different way to share our struggles with our chronic illness.
[38:27] When Ryan meets people and tells them about his health issues, he might say he has food allergies but then also explain how his conditions lead to a limited supply of energy, and then tell about the Spoon Theory. It’s a helpful tool we can all use, going forward.
[39:08] Our listeners can learn more about the Spoon Theory by going to Christine Miserandino’s website, ButYouDontLookSick.com.

[40:05] To connect with others impacted by eosinophilic diseases, please join APFED’s online community on the Inspire Network at APFED.org/Connections.
[40:14] Ryan thanks Holly for sharing information about the Spoon Theory. It means a lot to Holly that we have a platform to reach a lot of people. Holly hopes if you are struggling with a chronic illness that you are not alone and you can use this tool to bring your loved ones and friends closer. Maybe weed out the people who aren’t helping.
[41:15] Holly thanks APFED’s education partners, AstraZeneca, Bristol Myers Squibb, GlaxoSmithKline, Sanofi, and Regeneron, linked below, for supporting this episode.
[41:26] Ryan shares how he just met his partner’s friend and by discussing symptoms while picking a place to eat, it turns out she was diagnosed last year with EoE. It’s unusual for him to meet people with EoE out there randomly. Ryan is glad to be creating this resource for people. Holly agrees 1,000%.
“Approximately 10 years ago, fatigue became a real challenge for me and as I researched options on how to manage fatigue, I came across the spoon theory, which is what we’re going to specifically discuss today.” — Holly Knotowicz
“[The Spoon Theory] is such an interesting story and it feels like such an easy way to convey what living with a chronic illness is like.” — Ryan Piansky
“We all have people in our lives whom we love dearly, but they could maybe be taking too many of our spoons, so you have to be thoughtful about when you plan time with them.” — Holly Knotowicz
[2:41] Gastro Girl became a popular part of the site. The company was bought but Jacqueline retained the URL, Gastro Girl, and the persona. She engaged on Twitter and then got a job at the American College of Gastroenterology (ACG) where she dug into GI and learned the pain points from both the provider and patient sides.
[3:09] Jacqueline saw that patients didn’t have the resources, access, and champions they needed so she created a company out of Gastro Girl to meet their needs. In 2019, Gastro Girl partnered with ACG to create a provider-focused platform, GI On Demand, that provides ACG members and their patients access to multi-disciplinary GI expertise.
[4:02] Ryan tells about his experiences with APFED as a person living with Eosinophilic Esophagitis and Eosinophilic Asthma. His family is passionate about the patient experience for people with eosinophilic disorders. Ryan sees that Jacqueline is also passionate about empowering patients.
[4:39] Jacqueline loves that patients and their loved ones are involved in advocacy. There is no better voice than those who walk on that health path. Jacqueline, as a child, saw her grandmother needing laxatives to feel better. Jacqueline didn’t understand. Then Jacqueline got a dog with digestive problems that needed veterinary help.
[5:51] Jacqueline was fascinated by the whole connection between the digestive system and our overall health. When she started Gastro Girl she was going through a lot of trauma and lost a lot of weight. She was diagnosed with irritable bowel syndrome (IBS).
[6:48] Gastro Girl brings together resources and information that run the gamut of digestive-health-related topics. It has resources and partners, like APFED, that cover all the areas of GI and bring the pieces together to help patients find the information they need, when and how they need it.
[7:21] Holly tells how she searched symptoms online, was able to find Gastro Girl, and did a deep dive to navigate many areas. Holly also tells how she saw herself in patients’ symptoms while she was helping in an EoE clinic before she was diagnosed with it.
[8:38] Gastro Girl has baseline content on what eosinophilic gastrointestinal disorders are and how they are diagnosed. Then it points to expert partners like APFED to speak to eosinophilic disorder topics and support in-depth. Gastro Girl focuses on symptoms and identifying diseases earlier to get into care quicker.
[9:25] The Gastro Girl podcast and YouTube channel have episodes on EoE. The comments that come in on the videos, like “EOE 101,” Jacqueline says are mind blowing. People say the videos help them identify what possibly could be going on and get them to seek care without alarming them.
[10:34] Gastro Girl offers evidence-based information and resources so that people know they can come to the site and find sites like APFED and the ACG that are trusted and credible, that will not send them down a rabbit hole and confuse them.
[12:07] A colleague of Jacqueline’s friend emailed Jacqueline with her young son’s symptoms. Jacqueline isn’t a doctor and can’t diagnose but the symptoms sounded like EoE. She recommended that the mother ask her son’s doctor if he could be tested. Two months later she heard he had eosinophilic asthma and EoE.
[13:21] Jacqueline says the biggest message we could get out there is for patients to pay attention to credible resources. She cautions patients to be mindful and use discretion when going to the sites for their health information. Dr. Google is not great. Holly directs patients toward specific videos or episodes that offer the best information.
[14:41] There are some times when Jacqueline does not approve a comment to a podcast or video if she is concerned the comment will do more damage than good. She urges listeners and viewers to exercise caution on what comments they listen to.
[16:22] Jacqueline has interviewed many patients, caregivers, and providers in the GI space. She says patients want to be heard and feel that they are being listened to and that they’re getting access to the right information so they can feel better. That can mean different things to different patients in their quality of life.
[17:47] Gastro Girl is about putting the patient at the center. Being patient-centric is seeing the patient’s view first. Gastro Girl supports patients having collaborative care and shared decision-making, giving information so they are more educated and informed as they ask questions and collaborate on decisions with their providers.
[19:25] Thinking critically and asking the right questions makes you an active participant in your healthcare journey, and hopefully, gets you to a better result.
[20:26] Jacqueline learns every day from her podcast guests. She has learned that healthcare providers, gastroenterologists, dieticians, and psychologists care about their patients. They want patients to get better. Their passion and caring are overwhelming.
[21:20] Jacqueline has learned that patients are resilient and committed, not only to finding better ways to have a better quality of life but also to advocacy efforts, helping, and lifting their fellow patients. Jacqueline says together we are much stronger than to be isolated by ourselves, dealing with big healthcare issues.
[22:55] Many doctors are involved in research, speaking, webinars, and educating fellow providers and patients. It’s mind blowing to Jacqueline!
[23:16] Running Gastro Girl and GI on Demand during COVID-19 was hard and stressful for Jacqueline. She was inactive and gained weight. She worried about taking care of others, but not herself. She is back on track, exercising and losing weight.
[26:08] Jacqueline says we have to be kind to ourselves; we have to have compassion and grace towards ourselves. We’re very kind and compassionate to others and give them grace. Make sure you extend grace to yourself.
[26:27] Jacqueline cites Tara Cousineau, author of The Kindness Cure. Positive reinforcement is better than beating yourself up. When you feel good, you’re going to do the good things next time.
[27:46] Jacqueline tells about GI on Demand. It’s provider-focused with multiple disciplines available for healthcare providers. Providers and patients can search for dieticians, GI psychologists, and genetic testing and counseling. This helps GI providers and their practices to help their patients better.
[31:24] Jacqueline plans for Gastro Girl to continue to do great work for patients. She is working on an educational bus tour, “Gastro Girl to the Rescue Bus Tour!” with partners such as APFED, to bring information to individuals at home. Patients can be guided to resources, like getting a proper diagnosis or finding a provider. It’s a lot of logistics!

[33:30] Ryan and Holly thank Jacqueline Gaulin again for joining them. Ryan would be happy to go on the Gastro Girl podcast any time to talk more! Holly thanks APFED’s education partners, linked below, for supporting this episode.

About Jacqueline Gaulin
An early champion of a patient-centric, collaborative, and multidisciplinary approach to gastrointestinal health, I worked for several early-stage health-related start-ups, including Revolution Health. During my time with the American College of Gastroenterology (ACG), I led the ACG into the digital age by creating and executing strategic communications plans and patient education campaigns around a variety of digestive health topics and related research, including IBS, IBD, Liver disease and colorectal cancer awareness.
After six years with the ACG, my passion for empowering patients inspired me to evolve my popular blog, Gastro Girl, into a digital health company in 2015, Gastro Girl, Inc., to provide patients with access to the GI expertise and evidence-based information and resources they need to follow their doctor’s treatment plan and make informed health care decisions with their care team for better health outcomes.
[2:27] Dr. Peterson takes care of all sorts of eosinophilic gastrointestinal diseases. She works closely with Dr. Gerald Gleich, as well. Dr. Peterson is a mother of a boy living with eosinophilic disease for 10 years, so she experiences both sides of eosinophilic diseases. She loves her job.
[3:23] Familial risk refers to the risk of the disease in a patient when a family member is affected, compared to the general population. Looking at a proband (patient), is a first-degree family member (parent, sibling, or child) also affected with eosinophilic disease? Is a second-degree family member (grandparent) affected? Are cousins?
[3:58] Dr. Peterson’s is trying to see if and how far out the risk for the disease goes within a family. Based on that, you can get an idea if some shared genes are involved, vs. shared environmental influence of the disease within family members. That’s the idea of doing family risk studies in complex diseases; eosinophilic diseases are very complex.
[4:44] Dr. Peterson explains how she conducts a family risk study in Utah. The Utah Population Database is very helpful. The University of Utah has partnered with The Church of Jesus Christ of Latter-day Saints for large genealogical pedigrees that allow tracking disease through expanded pedigrees, with privacy and security limitations.
[5:24] It’s necessary to clarify physician coding to make sure it’s realistic and coded appropriately so that results are believable. It’s very hard to recruit family members. Dr. Peterson feels extremely blessed to live in that area. The families are generous and giving. She also believes all eosinophilic families are generous.
[6:34] The farther out you can identify the risk for disease, the more likely you will find a common gene that could be implicated in disease risk or onset. If the disease is tracked in extended relatives, it implies a shared gene more than a shared environmental risk. If the disease is isolated within nuclear families, it may indicate an environmental risk.
[7:39] In doing familial research, Dr. Peterson is trying to develop a risk score. People are getting pretty good at diagnosing EoE, but Dr. Peterson would not say that the non-EoE EGIDs are well-established or well-diagnosed. They are missed commonly and often. To have a risk score from the extent of the disease in a family is helpful.
[8:12] Dr. Peterson notes that studies of cancer risk in extended families have established cancer risk scores and related screening that is needed.
[8:43] Dr. Peterson coauthored a paper in November 2020 about the familial risk of EoE, published in the Clinical Gastroenterology and Hepatology Journal. She and her colleagues looked at nuclear families. They were looking for how many members of the nuclear family of an EoE patient have esophageal eosinophilia.
[9:28] They used a questionnaire on allergies, food allergies, and symptoms. They pulled in around 70 first-degree family members and scoped them for eosinophilia, pulled the records on the rest of the family members if they had been scoped, and assessed the risk for eosinophilia.
[9:51] Including the records, and assuming that everyone who hadn’t had an endoscopy was negative, they found the risk for esophageal eosinophilia in first-degree family members was 14%, bordering on the familial risk for celiac disease. It’s probably higher since they assumed anyone who hadn’t been scoped didn’t have eosinophilia.
[10:19] They called it esophageal eosinophilia, because the guidelines for diagnosing EoE suggest that the patient must complain of symptoms, and these family members did not have symptoms. It was interesting to find this high prevalence of eosinophilia in the nuclear family members of EoE patients. They had a higher risk of allergy, as well.
[11:14] Dr. Peterson explains the differences between esophageal eosinophilia and eosinophilic esophagitis (EoE). Esophageal eosinophilia means eosinophils are in the esophagus, >15 per high-power field in a biopsy. That could qualify as EoE when you go through the criteria of symptoms.
[12:19] We call it esophageal eosinophilia while we rule out everything else that could cause that cell to get recruited into the esophagus. It could be an allergic reaction to a medication, larger eosinophilic disorders, or parasitic infections. Esophageal eosinophilia means you had that initial biopsy that puts you at risk for EoE.
[13:06] You have to go down the diagnostic steps: Do I have symptoms? Do I have anything else that explains it? If you have nothing else that explains the eosinophils, and you have esophageal dysfunction, then you can call it EoE.
[13:33] Dr. Peterson, speaking personally, believes that educating doctors to ask patients about EoE symptoms would be useful in diagnosing EoE. People cope. You don’t want to focus on your symptoms because you want to be able to focus on your life. If symptoms aren’t brought to a doctor’s attention, a diagnosis can get missed.
[16:47] Dr. Peterson discusses risks for EoE in families where allergies are present. Dr. Peterson is involved currently in another familial study to find more information about the risk of EoE where there are allergies in a family. In the preliminary data, it looks like there is a link with asthma. Asthma and EoE in a family seem to track together.
[17:31] The risk of EoE seems to be higher with additional allergies within a family. Dr. Peterson says they are cleaning up the data to get a better answer. It appears that allergies in general go along with some of the genes that have been identified in EoE. Watch for Dr. Peterson’s papers going forward!
[19:05] They looked at around 300 eosinophilic gastroenteritis (EGE) patients and about 170 eosinophilic colitis (EoC) patients. If you have a proband with EoE, is there a higher family risk of having EGE or EoC? It looks like EoE puts you at higher risk of these other conditions. But with such low numbers in the study, the jury is still out.
[20:37] They looked at EGE codes because there is a subset of patients who have eosinophilic disease in their stomach and small bowel who don’t have EoE. They found that in patients who have eosinophilic disease in the stomach or the small bowel, EoE is still commonly seen throughout families. EoE seems to be a common theme.
[21:54] Down the road, Dr. Peterson hopes to be able to identify enough families that they might be able to start looking at genes that might put people at risk for more extensive disease.
[23:07] Dr. Peterson discusses the difficulty in diagnosing eosinophilic colitis, inflammatory bowel disorder, and other disorders. Having eosinophils does not categorize you as an EGID patient. There are other disorders where eosinophils are present. We need a better understanding of eosinophilic colitis.
[25:21] Eosinophilic asthma and eosinophilic fasciitis are disorders that Dr. Peterson has not studied but are in the Institutional Review Board approved documentation for future study.
[26:18] Dr. Peterson addresses whether your degree of risk for an EGID increases if you have an immediate family member with an EGID, vs. a second cousin with an EGID. She would say yes, based on the hazard ratios in the data and knowing that eosinophilic disorders are complex and twin studies show an environmental influence.
[27:28] Dr. Peterson asks patients about their family history, especially when they have other symptoms besides EoE. It makes her more aware of what to test.
[29:10] A paper Dr. Peterson is about to submit studied family members who weren't affected, who were siblings of probands. Their mucosa wasn’t entirely normal. They may be pre-diagnostic. These are patients who need to be followed. There may be things that set people up for the development of this disease, in the right environment.
[31:04] Something fascinating from the familial study is the challenge of diagnosing EGIDs. Fifty percent of the people they brought in hadn’t had an endoscopy. We need to be proactive in identifying diseases in patients. In the study, there are a lot of general GI symptoms coded that Dr. Peterson wonders if they may be missed EGIDs.
[32:34] The NIH gave Dr. Peterson’s team funding and they were able to do linkage analysis on several de-identified families that were at high risk for EGIDs. It looks like multiple genes have the potential to be involved. Personalizing medicine would be applicable if there were just one specific gene involved.
[33:23] Down the road, we may find some genes that portend higher risk and other genes that portend risk where we can do preventative environmental care. We can develop risk scores to identify risks and point to interventions.
[34:10] Mary Jo thanks Dr. Peterson for joining us today to share her expertise and help us learn and understand.
[34:36] Future research needs to be done where we are able to recruit patients and do more work looking at genetic linkage and get to the point where we can diagnose and identify non-EoE EGIDs well enough to explore them more, including eosinophilic colitis. Defining those diseases is necessary and needed.
[35:16] A lot of what Dr. Peterson is trying to do is to look further into combined diseases and hypereosinophilic states to determine if there is some gene within families that may help her to develop other therapies not focusing only on the GI tract but on a global approach to health for these patients.
[35:48] There is current research being done to find less invasive ways of identifying disease, such as imaging, so people don’t have to undergo endoscopy. That research is being done on the commercial side.
[36:44] Dr. Peterson has been looking at food-specific antibodies. Also, research by other doctors is being done to identify other markers of the foods that often trigger the disease. There has been some interesting preliminary data. This can help patients to eliminate fewer foods.
[37:27] Dr. Peterson has been looking at less invasive ways to identify non-EoE EGIDs in ways that can avoid biopsy.
[38:04] What’s being done to study Barrett’s esophagus? Dr. Peterson speaks of past and planned research, using the Utah population database. They looked at the risk for Barrett’s esophagus in patients with EoE and it was eight times higher than the normal population. Dr. Peterson correlates risks with reflux for Barrett’s and EoE.
[39:26] There are still questions about which comes first, EoE, Barret’s esophagus, or reflux. She also talks about the relationship between achalasia, allergic diseases, and EoE.

“When we study familial risk, we’re looking at the risk of the disease in a patient when a family member is affected, compared to the general population.” — Dr. Kathryn Peterson
“I think allergies, in general, kind of go along with some of the genes that have been identified in EoE.” — Dr. Kathryn Peterson
“Fifty percent of the people we brought in [to this familial risk study] hadn’t had an endoscopy. We need to be proactive in identifying diseases in patients.” — Dr. Kathryn Peterson
About Dr. Kathryn Peterson
Kathryn Peterson, MD is a Professor of Gastroenterology at the University of Utah Health. She is certified by the American Board of Internal Medicine.
Dr. Peterson specializes in diagnosing and treating diseases of the digestive system including eosinophilic esophagitis, Barrett’s esophagus, and inflammatory bowel disease. She completed her medical degree at the University of Texas Southwestern, followed by residency and a fellowship at the University of Utah and a master's program in Epidemiology at Harvard University.
[2:46] Dr. Muir started her own EoE clinic at CHOP (Children’s Hospital of Philadelphia) as part of their Center for Pediatric Eosinophilic Disorders. She sees patients at the clinic, then she can bring questions from the clinic to the lab and talk about them as a group.
[3:28] Dr. Muir explains esophageal remodeling. There is remodeling that happens in the epithelial compartment of the esophagus. Then there’s remodeling that happens underneath the surface in the lamina propria. For the most part, when people talk about remodeling in eosinophilic esophagitis, they refer to the remodeling happening below the surface.
[3:50] There is a burgeoning field dedicated to studying the surface of the esophagus, and Dr. Muir is also very interested in that. For today’s purposes, we are talking about the remodeling that happens under the surface.
[4:03] Eosinophils that get to the esophagus secrete chemicals that excite the cells below the surface to secrete collagen. Collagen is the glue that holds the body together. They’re secreting glue to help the esophagus hold together, and the esophagus gets stiffer and stiffer, over time. That is remodeling. It’s the body trying to heal itself.
[5:04] Are children and adults equally at risk for remodeling? Patients develop a stiffening of the esophagus more, later in life. It is thought that the more years you have this inflammation, the more stiff your esophagus gets. There are patients six to nine years old who already have signs of stiffening.
[5:28] Dr. Calies Menard-Katcher from Colorado published a paper where she described all of the eosinophilic esophagitis patients at her institution who got dilated. Dilation is the process of a balloon stretching your esophagus open when it’s too narrow. She had patients as young as six in her cohort that she described as having EoE strictures.
[5:49] Remodeling happens with younger patients but we’re not as good at finding it.
[6:08] Any type of inflammation in the GI tract can lead to some stiffening. The typical gastrointestinal disease that we think of as remodeling is Crohn’s Disease. An inflammatory process happens in the small bowel or colon that leads to narrowing and stiffness in the intestines.
[6:28] Also GERD (reflux) can lead to stricture, over time. It is just much more rare to see a GERD-induced stricture as opposed to EoE.
[7:13] We are not sure, but to some extent, we think of remodeling as not being reversible. Once there is a certain degree of stiffness, the esophagus does not seem to open up without these dilations. If you can control the inflammation, you can halt the stiffening. Maybe there is some degree of reversibility.
[7:44] In the Phase 2 dupilumab trials, investigators found that patients on dupilumab were seen to gain two millimeters in diameter of the esophagus, compared to the patients on placebo. We may be able to prevent some remodeling if we catch it soon enough. More research is needed.
[8:33] Dr. Muir tells of the work she is doing in her lab. They take biopsies from patients and grow collagen-secreting fibroblasts in a dish. The research is to find out what calms the fibroblasts down from actively secreting collagen.
[9:22] It’s tough to follow the symptoms of EoE when patients only have difficulty swallowing foods that are hard to swallow. If patients are not challenging their esophagus, they might not notice having daily trouble swallowing. It’s hard to ask a young kid who is eating a lot of soft foods if they feel like anything’s getting stuck.
[10:06] Dr. Muir will ask teenage patients, “Do you ever want to eat chicken? Do you ever want to eat steak?” A lot of times they don’t want to eat it, perhaps because it felt uncomfortable at some point in their life and they don’t want to eat it, not based on taste but on repeated bad events. It’s hard to tease out the symptoms, sometimes.
[10:27] Dr. Muir says, based on our Functional Luminal Imaging Probe (FLIP) studies, patients who had feelings of food that felt stuck in the last 30 days did seem to have a more narrow caliber esophagus. There is not a 100% correlation between symptoms and remodeling, but there seems to be some correlation.
[11:31] Ryan tells how patients have tendencies to get around their EoE symptoms, with a personal example of keeping food in his mouth and chewing it for a long time before swallowing. A scope would show he had bad inflammation of the esophagus. He had been diagnosed when young and was under treatment and on a restricted diet.
[12:26] Biopsies don’t always get a sample below the surface to check for fibrotic cells so it is hard to find remodeling with biopsies. There are some visual signs. Seeing rings or trachealization in the esophagus, or narrowing, can be signs that there is some remodeling under the surface.
[13:38] For kids who have a lot of trouble swallowing, Dr. Muir performs an EndoFLIP test regularly. The test catches subtle narrowing that may not be visible to the endoscopist. Doing this test gives the doctor more information and a better sense of the patient's phenotype, such as inflammation, the esophagus being stretchy, or being stiff.
[14:49] The EndoFLIP is a balloon with an imaging probe that includes a TV for the doctor to see how many millimeters the esophagus is in diameter as the balloon inflates along the whole body of the esophagus. It’s not an imaging test that goes to radiology. It’s a balloon that is blown up slowly with salt water and that gives this measurement.
[15:18] The EndoFLIP is a helpful tool to help determine who may have some more stiffening or determine exactly what the diameter of the esophagus is before starting treatment.
[15:33] One of the things that Dr. Menard-Katcher of Colorado, Dr. Ackerman of the University of Illinois, and Dr. Muir collaborated on was to look and see if they could find any markers in the esophagus that would relate to some of the things that are obtainable on biopsy or the esophageal string test.
[15:57] What they found was that periostin — a protein made by the epithelium and by the fibroblasts, which is known to activate fibroblasts, and is very high in EoE — seemed to correlate with the EndoFLIP measurements. This makes Dr. Muir think that there might be some potential for biomarkers to detect remodeling.
[16:16] The thing that everyone wants for this disease is to find a biomarker where we don’t have to do a scope. As far as finding a non-invasive biomarker, we’re not there, yet. There are some things going on at the tissue level that might clue us in on how distensible the esophagus is.
[17:18] The thing Dr. Muir worries about the most with long-term inflammation is that the esophagus is going to get more narrow over time. That will make patients more susceptible to food impaction (although not all patients with food impaction have a stricture).
[17:36] One worry is that the esophagus will get so narrow that an endoscope will not be able to pass a stricture. That will lead to more swallowing problems. That is what Dr. Muir hopes to be able to prevent as we get better at treating this.
[18:09] Any of the treatments that stop the inflammation and help get you below that “magical” 15 eosinophil count that we all strive for, will help prevent remodeling. So, once you get everything calm, hopefully, the remodeling process will stop. However, with the stiffening, the fibroblasts get more excited and have a hard time turning off.
[18:53] Simply turning off the inflammation will not turn off the fibroblasts. Many people within the GI space are looking at fibroblast-directed therapy, especially in Crohn’s disease, there’s a real need to prevent a lot of surgeries that are happening. Dr. Muir hopes to apply some of these to the esophagus, as well.
[19:16] In the study by Dr. Menard-Katcher, Dr. Ackerman, and Dr. Muir, there were 80 patients. Some were on swallowed steroid treatment and others were on an elimination diet. There were not enough patients on each therapy to find a significant difference in remodeling between the therapies. Patients in remission had better distensibility.
[19:44] Dr. Evan Dellon showed in a paper that patients who have sustained remission have fewer dilations, in the long term. While we don’t have a way to reverse the fibrosis that’s happened, we hope to prevent it from getting any worse. Dr. Muir’s research goal is to find something to calm fibroblasts down and prevent fibrosis or even reverse it.
[20:31] Dr. Muir explains that cells under the surface level are fibroblasts. When eosinophils and T cells come in and secrete antagonizing chemicals, the fibroblasts turn on and start secreting collagen. The fibroblasts also turn on when the epithelium is angry and inflamed. There is also evidence that surface cells can secrete collagen.
[22:46] Dr. Muir says it’s hard to know how far along in development some anti-fibrotic drugs are. We have many promising targets. Understanding how the remodeling happens is very important to be able eventually to treat this disease. Even though it seems like incremental progress, Dr. Muir believes research is moving the field forward.
[24:16] Dr. Muir says her EoE patients at CHOP are generous with their blood and tissue. Getting consenting control patients for lab studies involves a lot of leaps of faith and trust that scientists will grow your cells ethically. Dr. Muir feels lucky she has a good research team that explains things in lay terms to control patients.
[26:50] Dr. Muir’s team has videotaped pediatric EoE patients and control patients’ eating. The time EoE patients spent chewing and how long it took to swallow correlated to their esophageal distensibility measured by the EndoFLIP test. She believes that how we feed and the difficulty we have swallowing have to do with esophageal remodeling.
[27:41] That’s Dr. Muir’s next area of study. It’s being spearheaded by Dr. Kanak Kennedy, a fellow in Dr. Muir's lab, trying to figure out the relationship between pediatric feeding and remodeling.
[28:08] As part of their research, they are videotaping as many kids eating as they can. This involves many control patients who don’t have EoE. Another area of research is on the enzyme lysyl oxidase which organizes collagen into bundles and makes it stiff. She is looking into ways to decrease the organization of the collagen.
