Abstract
BACKGROUND: As standard triple therapies of achieve unsatisfactory eradication of Helicobacter pylori, several alternative regimens have been proposed. OBJECTIVES: To systematically evaluate whether sequential treatment eradicates H. pylori infection better than standard triple therapies and compare the risk of adverse events with these two regimens. METHODS: We searched electronic databases up to February 2008 for studies evaluating the efficacy of the 10-day sequential therapy vs. standard triple regimens for eradication of H. pylori. The pooled risk ratios (RR) and 95% confidence intervals (95% CI) were calculated. RESULTS: We identified 11 randomized trials, including eight full-text manuscripts and three abstracts. Pooled analysis demonstrated clear superiority of the sequential therapy over 7-day triple regimen with an RR of 1.23 (95% CI 1.19-1.27), and over 10-day triple regimen with a RR of 1.16 (95% CI 1.10-1.23). Adverse event rates were similar. For sequential therapy vs. 7-day triple therapies, RR = 0.96, 95% CI 0.70-1.31. CONCLUSIONS: Sequential therapy was associated with a higher eradication rate of H. pylori compared with both 7-day triple regimen and 10-day triple regimen.
