High dose dual therapy versus bismuth quadruple therapy for Helicobacter pylori eradication treatment: A systematic review and meta-analysis.
Medicine (Baltimore) 2019 Februrary
AIM: The aim of this study was to perform a systematic review and meta-analysis on high-dose dual therapy (HDDT) versus bismuth quadruple therapy (BQT) for Helicobacter pylori infection.
METHODS: Comparing HDDT to BQT were identified from PubMed, EMBASE, Cochrane library, CNKI, and Wanfang databases in Chinese up to March 2018. Statistical analyses were conducted using Review Manager 5.3 to compare the efficacy and side effects of these 2 therapies for H pylori infection. Dichotomous data were pooled to score the relative risk (RR) with 95% confidence intervals (CIs).
RESULTS: Four randomized clinical trials (RCTs) including 829 patients with a diagnosis of H pylori infection were assessed. Overall the meta-analysis showed that both HDDT and BQT achieved similar efficacy of intention-to-treat (ITT) eradication rate, 85.5% versus 87.2%, RR 1.01 (95% CI: 0.96-1.06), P = .63, and of per-protocol (PP) eradication rate, 88.4% versus 91.5%, RR 1.00 (95% CI: 0.96-1.04), P = .99, and adherence 97.8% versus 95.0%, RR 1.01 (95% CI: 0.99-1.04), P = .32, but side effects were more likely in BQT (14.4% vs 40.4%, RR 0.42 (95% CI: 0.32-0.54), P <.00001).
CONCLUSION: Both HDDT and BQT can achieve similar eradication rate for H pylori infection and adherence, and generally HDDT causes fewer side effects.
