Efficacy and Safety of Minocycline-Containing Bismuth Quadruple Therapies Versus Standard First-Line Bismuth Quadruple Therapies for Helicobacter pylori Eradication: A Systematic Review and Meta-Analysis
Abstract
Background: Growing antibiotic resistance and the limited availability of key components in standard Helicobacter pylori treatments have driven the search for effective alternatives. Minocycline, with its broad-spectrum activity and favorable pharmacokinetics, has emerged as a promising substitute. This meta-analysis compares the safety and efficacy of minocycline-containing bismuth quadruple therapy (MBQT) to conventional first-line BQT regimens, incorporating data from the recent study by Lin et al. Methods: The inclusion criteria were randomized controlled trials (RCTs) with a target population of both treatment-naïve and previously treated patients diagnosed with Helicobacter pylori (H. pylori) infection. The intervention received by eligible patients was a minocycline-bismuth quadruple therapy (MBQT) regimen containing bismuth, minocycline, proton pump inhibitors (PPI), and any additional antibiotic with a minimum period of 2 weeks of administration. We excluded study designs other than RCT and clinical trials that include patients without confirmed H. pylori infection, animal populations, in vitro experiments, and reports of other outcomes that did not include a minimum intervention duration of 2 weeks. A comprehensive literature search was conducted on PubMed, EMBASE, Cochrane Library, and ScienceDirect from inception to 20 May 2025. After screening via Rayyan, data were extracted on an Excel spreadsheet. Quality was assessed using the Cochrane RoB 2.0 tool. Eligible…
