Association Between Helicobacter pylori Exposure and Decreased Odds of Eosinophilic Esophagitis—a Systematic Review and Meta-analysis

Previous or current infection with Helicobacter pylori (exposure) has been reported to protect against eosinophilic esophagitis (EoE), perhaps due to H pylori-induced immunomodulation. However, findings vary. We performed a systematic review and meta-analysis of comparative studies to more clearly define the association between H pylori exposure and EoE.
