Abstract

INTRODUCTION: Vonoprazan, a novel potassium-competitive acid blocker, has a strong acid suppression effect and potent efficacy in acid-associated diseases, including Helicobacter pylori eradication. We performed a systematic review and meta-analysis to investigate the efficacy and safety of vonoprazan/amoxicillin dual therapy for H. pylori eradication.

METHODS: We conducted a systematic literature search through PubMed, Web of Science, EMBASE, and the Cochrane Library up to June 2022, to identify randomized controlled trials and cohort studies comparing vonoprazan/amoxicillin dual therapy and triple therapies for H. pylori eradication. Primary outcomes were cure rates and relative efficacy. Secondary outcomes included adverse events, dropout rate, and subgroup analysis.

RESULTS: Five studies with 1,852 patients were included in the analysis. The cure rates of vonoprazan/amoxicillin dual therapy were 85.6% with 95% confidence interval (CI) of 79.7-91.5% and 88.5% (95% CI: 83.2-93.8%) in the intention-to-treat and per-protocol analyses. The efficacy of vonoprazan/amoxicillin dual therapy was not inferior to that of triple therapy with pooled risk ratio (RR) of 1.03 (95% CI: 0.97-1.10) and 1.02 (95% CI: 0.98-1.08) in intention-to-treat and per-protocol analyses; while it was significantly superior to the omeprazole or lansoprazole-based triple therapy (RR = 1.15, 95% CI: 1.05-1.25, p = 0.001). For clarithromycin-resistant strains, vonoprazan/amoxicillin dual therapy showed…
