UnlabelledIn a controlled, prospective, randomized trial, 10 patients with Helicobacter pylori positive gastritis were treated either with triple therapy (tetracycline, ornidazole, bismuth subcitrate; T, Or, CBS), or omeprazole/CBS (O/CBS) to test the eradication rate of each treatment, its effect on gastritis and meal stimulated gastrin release.Method6 patients were treated with triple therapy and 4 patients with O/CBS for 2 weeks. Initially, and 0.5, 1, 3, 6, and 12 months after therapy, patients were investigated by a highly specific, quantitative Helicobacter serology, 13C-urea breath test and measurement of meal-stimulated gastrin release. After 3 and 12 months antral biopsies were taken endoscopically for rapid urease testing and culture. Activity of histological gastritis was graded.ResultsEradication for at least 12 months was achieved in 5 out of 6 patients with triple therapy. Serology normalized and gastritis activity improved. In all patients treated with O/CBS, HP was suppressed only temporarily. No eradication was achieved. Urease testing and histology proved to be reliable tests for detecting HP. Culturing of HP was successful in only 66% due to technical problems. The 13C-urea breath test was correct in all cases. The initially, increased meal-stimulated gastrin release was normalized after eradication of HP.Conclusion(1) Triple therapy is also successful in short term treatment in up to 80% of patients with HP gastritis and improves gastritis activity. (2) The combination O/CBS failed to eradicate HP in all treated patients. (3) The 13C-urea breath test and HP serology are reliable non-invasive parameters during follow-up. (4) Normalization of meal stimulated gastrin release after eradication of HP supports the hypothesis that HP induces increased gastrin release and hyperacidity.
