[Campylobacter pylori--relation to gastric pathology and the effect of bismuth therapy].

Twenty-four patients with symptoms of gastric dyspepsia and active chronic gastritis in the antral mucosa were examined for the presence of Campylobacter pylori before and after treatment with bismuth salts (12 patients) and antacids (12 patients). Bismuth, contrary to the used antacid, significantly reduced the finding of C. pylori in the antral mucosa and had a favourable effect on the active form of chronic antral gastritis.
