Minocycline in the eradication of infection: A systematic review and meta-analysis.

Background: Difficulty in obtaining tetracycline, increased adverse reactions, and relatively complicated medication methods have limited the clinical application of the classic bismuth quadruple therapy. Therefore, the search for new alternative drugs has become one of the research hotspots. In recent years, minocycline, as a semisynthetic tetracycline, has demonstrated good potential for eradicating () infection, but the systematic evaluation of its role remains lacking.

Aim: To explore the efficacy, safety, and compliance of minocycline in eradicating infection.

Methods: We comprehensively retrieved the electronic databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure, SinoMed, and Wanfang database as of October 30, 2023, and finally included 22 research reports on eradication with minocycline-containing regimens as per the inclusion and exclusion criteria. The eradication rates of were calculated using a fixed or a random effect model, and the heterogeneity and publication bias of the studies were measured.

Results: The single-arm meta-analysis revealed that the minocycline-containing regimens achieved good overall eradication rates, reaching 82.3% [95% confidence interval (CI): 79.7%-85.1%] in the intention-to-treat analysis and 90.0% (95%CI: 87.7%-92.4%) in the per-protocol analysis. The overall safety and compliance of the minocycline-containing regimens were good, demonstrating an overall incidence of adverse reactions of 36.5% (95%CI: 31.5%-42.2%). Further by traditional meta-analysis, the results showed that the minocycline-containing regimens were not statistically different from other commonly used eradication regimens in eradication rate and incidence of adverse effects. Most of the adverse reactions were mild to moderate and well-tolerated, and dizziness was relatively prominent in the minocycline-containing regimens (16%).

Conclusion: The minocycline-containing regimens demonstrated good efficacy, safety, and compliance in eradication. Minocycline has good potential to replace tetracycline for eradicating infection.
