ABSTRACT

OBJECTIVE: Eradication of H. pylori not only results in ulcer healing, but reduces recurrences essentially curing peptic ulcer disease. The purpose of this study was to evaluate the eradication rate of H. pylori and side effects with regard to three drug regimens. METHODS: 96 patients were included and divided into three groups 14 patients(group 1 OA) received omeprazole(20 mg b.i.d.) and amoxicillin(1.0 gm b.i.d.) for 14 days ; 12 patients (group 2 BAM) received colloidal bismuth subcitrate(CBS)(120 mg b.i.d.), amoxicillin(500 mg q.i.d.) and metronidazole(250 mg q.i.d.) for 14 days. ; 70 patients(group 3 OAC) received omeprazole(20 mg b.i.d.), amoxicillin(500 mg q.i.d.) and clarithromycin(250 mg q.i.d.) for 10 days. The diagnosis of the status of H. pylori was made by histology or culture or rapid urease test(CLO test). RESULTS: 1) The eradication rate of H. pylori was higher group 2(91.7%) and group 3(91.4%) than group 1(57.1%). 2) The total failure rate regardless of the regimens (n=96) was 13.5%(13 patients). 10 patients whose treatment failed were randomly assigned to receive retreatment with the alternative regimen of BAM or OAC. In retreatment group(n=10), the eradication rate of H. pylori infection was achieved in 100 %. 3) The side effects were oral burning sensation, odynophagia, nausea, epigastric pain, diarrhea, constipation, gas bloating. The side effects were negligible. CONCLUSIONS: 10-day therapy with omeprazole, amoxicillin and clarithromycin(OAC) achieved eradication rate of 91.4 %. The side effects were few and negligible. 10-day therapy with OAC was a safe and very effective regimen for the eradication of H. pylori infection.
