No results posted yet for this study

Summary

Purpose:

1. Determine if oral quercetin increases the expression of claudin-4 in the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD); and
2. Determine whether the increase in claudin-4 by oral quercetin is accompanied by improvement in the barrier function and acid resistance of the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD)

If interested, participants will be consented and provided a questionnaire to complete as part of the study. Participants will undergo endoscopy for routine care and will have up to 8 esophageal biopsies (small tissue samples) taken for the research study. After endoscopy, participants will be contacted to begin a 6 week treatment period with study drug (Quercetin, taken twice daily).

At the end of the 6 week period, participants will be scheduled to have blood drawn and to have a follow-up endoscopy with biopsies performed for the research study.
