Eosinophilic esophagitis (EoE) is of increasing prevalence and believed to result from allergic processes. Helicobacter pylori has been inversely associated with allergic diseases, but there is no known relationship between H pylori, EoE, and esophageal eosinophilia. We investigated the association between esophageal eosinophilia and H pylori infection.


We performed a crosssectional study of data, collected from a US pathology database, on 165,017 patients in the United States who underwent esophageal and gastric biopsies from 2008 through 2010.
