Characteristics and Inflammatory Markers in Children With Eosinophilic Esophagitis (EoE)

Overview

Single center observational and specimen banking study for children with eosinophilic esophagitis EoE to gauge natural history and inflammatory markers

Participants with a diagnosis of EoE are recruited from Rady Children's Hospital Eosinophilic Gastrointestinal Disorders (EGID) during routine clinic and/or endoscopy visits. Medical information including clinical symptoms, endoscopy, histopathology, medical and surgical history, lab and imaging findings, are entered into a UCSD database at each clinic or endoscopy visit. Blood and biopsy specimens are procured and utilized for analysis of inflammatory molecules and for isolation of structural cells. This protocol continues our clinical database and sample collection in children with EoE. The database provides a cohort of EoE patients for studies of natural history, therapeutic response, and disease progression. In a relatively new disease of increasing incidence, these studies will provide information on disease progression and the clinical characteristics of patients who have varying disease phenotypes as well as the associations between clinical phenotypes, molecular changes, and disease course. The procurement and storage of tissue, cells, and serum samples provides a repository for studies of EoE-related molecules and peripheral markers in clinically phenotyped patients. In addition, the study of these esophageal cells will provide an in vitro model system for assessing the molecular mechanisms of disease pathogenesis in EoE.
