[Campylobacter pylori in patients with chronic gastritis and gastric and duodenal peptic ulcer].

The presence of Campylobacter pylori was studied in biopsy material from gastric mucosa taken by guided biopsy during fiber gastroduodenoscopy from 101 patients with chronic gastritis (n = 50), peptic gastric ulcer (n = 28), peptic duodenal ulcer (n = 7), gastric cancer (n = 10) and gastric polyposis (n = 6). Campylobacter pylori was found in various quantity--moderate (++) and considerable ( )--in 64% of the patients with chronic gastritis, in 85.7% of the patients with peptic gastric ulcer and in 100% of the patients with peptic duodenal ulcer as well as in half of the patients with gastric cancer and polyposis. The quantity of Campylobacter pylori correlated with the severity of the inflammatory process and the degree of atrophy of the gastric antral mucosa. A tendency toward seasonal incidence of Campylobacter pylori infection of gastric mucosa was established: 78.69% of the patients examined during spring time (April-May) and 60.0% of the patients examined during winter time (January-February) had Campylobacter pylori infection. This explains to a certain extent the seasonal exacerbations of the pathological process in chronic gastritis and peptic ulcer. The development of a well expressed chronic atrophic gastritis is in direct relation with the greater quantity of Campylobacter pylori in the gastric mucosa. The study reveals the pathogenetic relations between the presence and quantity of Campylobacter pylori and the development and evolution of chronic gastritis and peptic gastric and duodenal ulcer.
