title: Antral histopathological changes in acid peptic disease associated with Helicobacter pylori.
abstract: The histopathology of the antral mucosa of patients with acid peptic disease was studied in relation to Helicobacter pylori infection. Three hundred and fifty-five patients underwent gastroscopy and biopsy on 443 occasions. During each gastroscopy, two antral samples were taken for Rapid Urease Test (RUT) for H. pylori and two antral samples for histopathology. Haematoxylin and Eosin and modified Giemsa stained sections were studied. Histopathological changes in the antrum and the density of H. pylori were graded according to the Sydney System criteria. There was a significant association between the RUT and histology results for detection of H. pylori. The overall prevalence of H. pylori was 61.4% with a maximum incidence in the third and fourth decades of life, and an equal sex distribution. H. pylori colonisation was seen in 90.7% of patients with duodenal ulcer, 66.7% with gastric ulcer and 44.3% with non-ulcer dyspepsia. H. pylori colonisation was associated with more severe antral chronic active gastritis, lymphoid follicles, intestinal metaplasia and dysplasia. Elimination of H. pylori by treatment with anti-H. pylori regimens resulted in regression of the changes.
