Changing Patterns of <i>Helicobacter pylori</i> Gastritis in Long‐Standing Acid Suppression

Abstract

In H. pylori-positive subjects with GERD, long-term acid suppression leads to a shift from antral- to corpus-predominant gastritis that can be prevented by prior eradication. The shift is accompanied by an increase in corpus atrophy. H. pylori infection should be eradicated prior to long-term acid suppression with proton pump inhibitors.
