Abstract
Background: A shorter treatment duration potentially offers the advantage of reducing adverse events (AEs) and enhancing patient compliance for Helicobacter pylori eradication. However, the difference in eradication rates between short-duration vonoprazan-based regimens and fourteen-day proton pump inhibitor (PPI)-based therapy remained unknown. Objective: This meta-analysis aimed to compare the efficacy and safety of ten-day vonoprazan-based regimens with fourteen-day conventional PPI-based therapy for H. pylori eradication. Methods: We performed a comprehensive literature search up to November 28, 2023, using PubMed. A random-effects model was applied to conduct a meta-analysis to determine the pooled Odds Ratio (OR) with 95% confidence intervals (CIs). Results: This meta-analysis included four randomized controlled clinical trials with 1560 patients. The H. pylori eradication rate of ten-day vonoprazan-based regimens was comparable to that of fourteen-day PPI-based therapy (88.7% vs 82.9%, OR 1.53, 95% CI [0.85-2.75], p = .16) in ITT analysis. The incidence of AEs in ten-day vonoprazan-based therapy was also similar to the control group (11.2% vs 17.6%, OR 0.66, 95% CI [0.33-1.31], p = .24). Conclusion: Current evidence suggests that the ten-day vonoprazan-based regimen is as effective as fourteen-day PPI-based therapy in eradicating H. pylori, with comparable AEs. However, additional research is required for confirmation.
