STUDY OF HELICOBACTER PYLORI ERADICATON RATE OF BISMUTH-CONTAINING QUADRUPLE REGIMEN IN PATENTS WITH CHRONIC GASTRITS
Background: Quadruple therapy with bismuth was considered as a promising regimen in the eradication of Helicobacter pylori in the population with clarithromycine- resistant high rate, but data in Vietnam was still limited. This study is aimed at determining the eradication rate of quadruple regimen and its side effects in the patients with chronic gastritis. Patients and methods: 98 patients with chronic gastritis histologically diagnosed and postive with rapid urease test were enrolled. Patients received Rabeprazole 20 mg bid, Pepto bismol 2tab bid, tetracyclin 1000 mg bid and Metronidazole 550 mg bid for 10 days. Results: Eradication rates of quadruple regimens with bismuth were 91.8% in ITT analysis and 94.7% in PP analysis. Rate of compliance was 96.9%. The side effects were minor and transient. Conclusion: Quadruple regimen with bismuth showed a high rate of H. pylori eradication and a good tolerance in patients with chronic gastritis in central Vietnam.
