Background and aims The decreasing Helicobacter pylori eradication rate and the increasing antibiotic resistance trend are of great concern. Therefore, new and effective therapies are needed for H . pylori infection. We conducted a systematic review and meta‐analysis to assess the efficacy and safety of semisynthetic tetracycline regimens in H . pylori treatment. Methods PubMed, EMBASE, and the Cochrane library were searched. The outcome indicators were the eradication rate, risk ratio (RR, ie, the risk of the semisynthetic tetracycline regimen relative to the control), and 95% confidence interval (95% CI). Controls were patients undergoing any other treatment without semisynthetic tetracycline. Results Twenty‐three studies with 5240 participants were included. The eradication rates of triple regimens with semisynthetic tetracyclines in most studies were less than 70% in both the intention‐to‐treat (ITT) and the per‐protocol (PP) analyses. The pooled eradication rates of quadruple therapies with doxycycline and controls were 95% and 84% in the PP analyses, respectively. The pooled RR associated with efficacy in the quadruple therapy with doxycycline group compared with the control group was 1.12 (95% CI: 1.04–1.20) in the PP analysis. The pooled RR of side effects in the quadruple therapy with doxycycline group compared with the control group was 1.01 (95% CI: 0.65–1.55). Conclusion Seven‐day and ten‐day quadruple therapy with doxycycline might be an optional first‐line therapy. The safety of regimens containing semisynthetic tetracyclines was relatively satisfactory. However, the triple regimen is not recommended.
