Morphological Markers of Gastroesophageal Reflux Disease (GERD)

Status Active, not recruiting

Clinical Trial Summary

The purpose of this project is to learn more about a new and promising way to diagnose acid reflux disease using a very high-powered microscope. This special microscope provides much finer detail than typical microscopes previously used for diagnosing reflux, and may help doctors to better identify children with acid reflux.

Clinical Trial Description

This will be a prospective case control study. Children between the ages of 8 and 18 with suspected gastroesophageal reflux disease (GERD) or eosinophilic esophagitis (EoE) based on symptom criteria and who have been scheduled for esophagogastroduodenoscopy (EGD) by their primary gastroenterologist will be recruited. Children who do not have any history of esophageal disease or esophageal symptoms and are scheduled for EGD for other clinical indications (e.g. rule out celiac disease) by their primary gastroenterologist will be recruited and act as controls. Control subjects will also be given the opportunity to undergo esophageal MII-pH monitoring as part of their medical evaluation, but will not be excluded from analysis should they opt out of this part of the study. For all subjects, in addition to endoscopic evaluation, biopsies of the distal esophagus will be obtained for routine light microscopy (standard histology sample) as well as Transmission Electron Microscopy (TEM) analysis to determine the presence and magnitude of dilated intercellular spaces (DIS), and immunoblotting for e-cadherin cleavage ;
