Abstract Helicobacter pylori infection of the gastricmucosal surface was investigated in patients withhamartomatous fundic polyps or hyperplastic polyps andin patients without endoscopic evidence of disease(healthy subjects). Presence of H. pylori infection wasdetermined by culture, histologic examination, and theendoscopic phenol red test. Adherence of H. pylori wasevaluated with scanning electron microscopic examination of antral biopsy specimens. Bothprevalence of H. pylori infection (P 〈 0.001) and H.pylori adherence (P 〈 0.05) were less in patientswith hamartomatous fundic polyps than in healthy subjects and patients with hyperplastic polyps.However, the percentages of plasma cells in gastricmucosa that contained IgA and of gastric epithelialcells that expressed Lewis b did not differsignificantly among the three groups. These findings suggestthat defense mechanisms against the attachment of H.pylori other than IgA or Lewis b antigen are present inpatients with hamartomarous fundic polyps.
