title: Chronic gastritis in patients with gastric ulcer; a 10-year follow-up.
abstract: BACKGROUND
  The course of gastric ulcer disease and its relations to certain indicators of inflammation and Helicobacter pylori in the gastric mucosa were examined in a 10-year follow-up.
  
  
  METHODS
  Thirty-three patients with gastric ulcer were examined endoscopically with biopsies in 1981-82 and invited for re-examination in 1991-92. Twenty-one of them were able to comply with the invitation. A gastroscopy with biopsies was performed on each of these, and the results were compared with those of age- and sex-matched control patients with non-ulcer H. pylori-positive gastritis.
  
  
  RESULTS
  All the patients were H. pylori-positive at the first examination and had a persistent infection at the second examination, if they had not undergone a gastric resection. Thirteen patients had a non-operated stomach at the second examination. The grades of gastritis and intestinal metaplasia in the antrum at the second examination were significantly higher in the ulcer patients than in the controls (p = 0.009 and p = 0.04, respectively). Eosinophilic granulocytes in both the antral and the corpus mucosa had decreased significantly in the controls (p = 0.002 and p = 0.04, respectively) but not in the ulcer patients.
  
  
  CONCLUSIONS
  The results suggest that the course of ulcer-associated H. pylori-positive gastritis is different from that of non-ulcer-associated H. pylori-positive gastritis and that abnormal eosinophilic infiltration persists in patients with gastric ulcer.
