Background: To assess effects of esomeprazole-based therapies and others (PPIs) on Helicobacter pylori eradication when co-administered with antibiotics.
Goals: Using the terms 'H. pylori eradication' and 'esomeprazole', we searched Medline, Embase, and the Cochrane Library (2000-2005) and conducted a manual search of related Chinese journals to identify randomized controlled trials (RCTs) that compared the treatment effects of esomeprazole and other PPI therapies in patients with H. pylori infection.
Results: Of the 75 articles screened, 11 RCTs including 2,159 subjects were included in the meta-analysis. The mean H. pylori eradication rates (intention-to-treat, ITT) with esomeprazole + antibiotics was 86%, a rate comparable with other PPI therapies, 81% (ITT); the odds ratio (OR) was 1.38 (95% CI = 1.09-1.75). A focused meta-analysis of 6 selected high-quality studies was produced an OR of this comparison that was closer to one (1.17, 95% CI = 0.89-1.54), with the results being statistically homogeneous. Sub-analysis that included only studies comparing different does of esomeprazole with omeprazole or pantoprazole did not reveal significant differences. No additional serious adverse events were reported.
Conclusions: Esomeprazole-based triple therapy may effectively eradicate H. pylori infection and promote favorable outcome with good tolerance and offers comparable efficacy to omeprazole-based therapy.
