Treatment with a proton pump inhibitor promotes corpus gastritis in patients with <i>Helicobacter pylori</i>‐infected antrum‐predominant gastritis

Abstract

Proton pump inhibitor treatment stimulated the neutrophil reaction in the corpus mucosa of duodenal ulcer patients and of patients in whom antral neutrophil accumulation was more predominant than that of the corpus. This phenomenon may not be caused by increased bacterial density.
