The purpose of the study was to examine gastric mucosal morphological changes in patients with gastroduodenal pathology after eradication therapy for Helicobacter pylori (H. pylori). A hundred and thirty-eight patients (40 females and 98 males) were examined. Of them, there were 122 patients with duodenal peptic ulcer, 8 with gastric peptic ulcer, 5 with erosive gastritis, 2 with chronic atrophic antral gastritis, and 1 with non-atrophic gastritis. ⋯ Positive changes were observed mainly in the antral portion of the stomach. In patients with partial eradication, chronic inflammation and its activity became less. Two months and a year following therapy, positive changes in the gastric mucosa were absent in patients without H. pylori eradication.
