Аннотация
1. Helicobacter pylori status and the histology of the antral and oxyntic mucosa were evaluated in 25 patients with duodenal ulcer treated with a triple schedule of furazolidone, metronidazole and amoxicillin, and in 16 patients treated only with cimetidine. 2. Before treatment, H. pylori was detected in all patients. One month after treatment with the antimicrobial agents, H. pylori was not found in 18 (72.0%) of 25 patients treated with the triple schedule. In the patients treated with cimetidine (N = 16) the H. pylori tests continued to be positive after treatment. 3. Inflammatory activity and intensity of gastritis were significantly reduced in patients treated with the antimicrobial agents but not in cimetidine-treated patients. Three patients who had negative cultures and improvement of gastritis 1 month after treatment became H. pylori positive again within 2 months, with concomitant reappearance of gastritis. 4. This study provides additional evidence that histological gastritis observed in H. pylori-positive patients with duodenal ulcer is due to the presence of the microorganism.
