Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will enroll participants who have been diagnosed with Eosinophilic Esophagitis (EoE). Upon study enrollment, the participant will begin a proton pump inhibitor (PPI), Omeprazole 20mg twice daily. After taking Omeprazole for four weeks, the participant will have a Transnasal Endoscopy, and biopsies will be taken to determine the histological change. If the biopsies are abnormal, the participant continues Omeprazole and will undergo another endoscopy at eight weeks. The study aims to determine the percentage of children with Eosinophilic Esophagitis who improve with PPI use and to determine the length of time and effectiveness of PPI therapy in the management of EoE. 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.
