Increased reflux secondary bile acids are associated with changes to the microbiome and transcriptome in Barrett’s esophagus

Abstract excerpt

Bile acids are a major component of gastro-esophageal refluxate, thought to contribute to the development of Barrett’s esophagus (BE) and esophageal adenocarcinoma (EAC). As the microbiome shifts with EAC progression and bile acids influence bacterial composition, we examined these connections in a multi-center, cross-sectional study. We analyzed biospecimens from patients undergoing endoscopy using LC-MS to...
