■由于耐药性增加,经验疗法对幽门螺杆菌感染的根除率下降。最新的指南推荐基因型耐药指导治疗,但其临床疗效尚不清楚。
■我们研究的目的是评估基于基因型耐药性的定制疗法是否优于幽门螺杆菌感染的经验疗法。
■对随机对照试验(RCT)进行了系统评价和荟萃分析,比较了基于基因型耐药性的定制治疗与经验性治疗。
■我们从PubMed检索了相关研究,Embase,还有Cochrane图书馆.主要结局为幽门螺杆菌根除率,不良事件(AE)为次要结局。随机效应模型用于比较合并风险比(RR)与相关的95%置信区间(CI)。
■在我们的系统评价和荟萃分析中,共确定了12个合格的RCT,包含3940例患者。基于基因型耐药性检测的定制治疗的合并根除率始终高于经验性治疗组。没有统计学意义。在三联疗法中,通过意向治疗分析(ITT)和符合方案分析(PP)分析,定制组的根除率显著高于经验组(p<0.0001,RR:1.20;95%CI:1.12~1.29;p<0.0001,RR:1.20;95%CI:1.15~1.25).在四联疗法中,经验组的根除率更高(p=0.001,RR:0.93;95%CI:0.89-0.97;p=0.009,RR:0.95;95%CI:0.92-0.99).此结果对于铋四联疗法(BQT)和非BQT均为正确。关于总AE,定制组的合并率为34%,经验组为37%,两组之间没有发现差异(p=0.17,RR:0.88;95%CI:0.74-1.06)。
■总而言之,基于分子方法的定制治疗可能比经验三联疗法提供更好的疗效,但在根除幽门螺杆菌感染方面,它可能不会优于经验性四联疗法。需要更大和更个性化的RCT来帮助临床决策。

UNASSIGNED: The eradication rate of Helicobacter pylori infection with
empirical therapy has decreased due to increased drug resistance. The latest guidelines recommend genotypic resistance-guided therapy, but its clinical efficacy remains unclear.
UNASSIGNED: The purpose of our study was to evaluate whether tailored therapy based on genotypic resistance is superior to
empirical therapy for H. pylori infection.
UNASSIGNED: A systematic review and meta-analysis of randomized controlled trials (RCTs) comparing tailored therapy based on genotypic resistance with
empirical therapy was performed.
UNASSIGNED: We retrieved relevant studies from PubMed, Embase, and the Cochrane Library. The primary outcome was H. pylori eradication rate and the adverse events (AEs) was the secondary outcome. A random-effect model was applied to compare pooled risk ratios (RRs) with related 95% confidence intervals (CIs).
UNASSIGNED: A total of 12 qualified RCTs containing 3940 patients were identified in our systematic review and meta-analysis. The pooled eradication rates of tailored therapy based on the detection of genotypic resistance were consistently higher than those in the empirical treatment group, with no statistical significance. In triple therapy, the eradication rate was significantly higher in the tailored group than in the empirical group by intention-to-treat analysis (ITT) and per-protocol analysis (PP) analysis (p < 0.0001, RR: 1.20; 95% CI: 1.12-1.29; p < 0.0001, RR: 1.20; 95% CI: 1.15-1.25). In quadruple therapy, the eradication rate was higher in the
empirical group (p = 0.001, RR: 0.93; 95% CI: 0.89-0.97; p = 0.009, RR: 0.95; 95% CI: 0.92-0.99). And this result was true for both bismuth quadruple therapy (BQT) and non-BQT. Regarding total AEs, the pooled rate was 34% in the tailored group and 37% in the
empirical group, and no difference between the two groups was found (p = 0.17, RR: 0.88; 95% CI: 0.74-1.06).
UNASSIGNED: In conclusion, tailored therapy based on molecular methods may offer better efficacy than empirical triple therapy, but it may not be superior to empirical quadruple therapy in eradicating H. pylori infection. Larger and more individualized RCTs are needed to aid clinical decision-making.
