This study aims to learn more about the subset of children with Eosinophilic Esophagitis (EoE) who are on treatment with a proton pump inhibitor (PPI). EoE is an increasingly common allergic condition of the esophagus for which we have limited treatment options. This study will be helpful in evaluating the minimal time frame required for histological improvement with the use of high dose PPI. The study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE) and are recommended by their physician to begin PPI treatment with Omeprazole 20 mg twice daily. After taking Omeprazole for four weeks, the participant will undergo an unsedated Transnasal Endoscopy (TNE) in the outpatient clinic at Children's Hospital Colorado. TNE is a test in which the doctor inserts a skinny bendable tube with a camera through the nose to look directly into the esophagus (the tube connecting the mouth to the stomach when you swallow) and is an alternative method to assess esophageal mucosa without requiring general anesthesia. Biopsies will be collected during the TNE to determine if there is histological change. If the biopsies are normal, the participant will complete the study. If biopsies are abnormal, and EoE is still active, the participant will continue the Omeprazole and undergo the standard of care endoscopy at eight weeks. The participant will choose the type of endoscopy- unsedated TNE or esophagogastroduodenoscopy (EGD) under anesthesia. Participants will also complete surveys during study enrollment about medication compliance, Eosinophilic Esophagitis symptoms, anxiety, TNE experience, and undergo a physical exam. The investigators hypothesize that following the initiation of PPI for treatment of Eosinophilic Esophagitis, biopsies obtained will show decreasing eosinophil counts at four weeks, which is sooner than the previously reported eight-week period. Results from this study will be generalizable to the pediatric EoE population and the knowledge gained will provide key preliminary data to support clinical recommendations for pediatric EoE patients.
