Helicobacter pylori and intestinal metaplasia in antral mucosa. A study on their correlation.
To investigate the possible relation between Helicobacter pylori (HP) colonization and incidence of intestinal metaplasia (IM), antral biopsy specimens from a total of 263 subjects (167 had chronic gastritis, 12 gastric cancer, and 84 no histological changes) were examined. IM was observed in 27.7% of the HP positive specimens and in 18.3% of the HP negative biopsies (p = NS). Histochemical characterization of mucins showed that the percentage of HP colonization was not significantly different within various subtypes of IM. We do not find in this study any evidence to support the existence of a pathogenetic role of HP on the morphogenesis of IM in antral mucosa.
