OBJECTIVE: Helicobacter Pylori (H. pylori) treatment may be different depending on the host and microbial factors in each region. The study was planned to estimate the effect of two 10-day esomeprazole containing clarithromycin and levofloxacin sequential therapies on H. pylori treatment. MATERIALS AND METHODS: Totally, 186 H. pylori-infected patients with gastro-duodenal ulcer who had not yet received treatment for infection, were enrolled. We randomly designated patients to group A (N = 94) who treated with esomeprazole 40 mg and amoxicillin 1 g bid during the early half of treatment, and continued the same dose of esomeprazole with levofloxacin 500 mg and tinidazole 500 mg bid during the second half of treatment and Group B (N = 92) who treated with the identical treatment excepting clarithromycin 500 mg bid as a substitute of levofloxacin. To assess eradication, C14-urea breath test was implemented 8 weeks afterward treatment. RESULTS: Finally, 172 patients completed the trial. We calculated 85.1% (95% confidence interval [CI] = 77.9–92.3) and 83.7% (95% CI = 76.2–91.2) eradication intention-to-treat analysis (P = 0.302) and so, 93.0% (95% CI = 87.6–98.4) and 90.0% (95% CI = 83.6–96.3) eradication by per-protocol analysis (P = 0.420) for Group A and B, respectively. No significant difference was seen among regimens. Drug adverse reactions were not significantly different between regimens. Group A had a 97.8% adherence rate to treatment and Group B had 98.9%. CONCLUSIONS: Both esomeprazole containing sequential regimens including levofloxacin and clarithromycin showed good eradication rates in spite of significant differences in antimicrobial resistance patterns in vitro. The efficacy of esomeprazole in lowering gastric acidity beside its antimicrobial effect should be considered in H. pylori regimens.
