背景:多西環素可用于根除幽門螺桿菌(Hp)感染,但尚缺乏大樣本研究證實其有效性和安全性。目的:探討多西環素根除Hp感染的有效性和安全性。方法:檢索中國知網、萬方、維普和PubMed、Embase、Web of Science、Cochrane Library等數據庫,收集比較多西環素和其他抗菌藥物根除Hp感染的相關文獻,檢索時間均為建庫至2023年10月。采用RevMan 5.3軟件行meta分析。結果:最終納入19篇文獻、共3 686例Hp感染患者。含多西環素方案的意向性治療(ITT)根除率(82.51%對73.65%;OR=1.72,95% CI: 1.42~2.07,Plt;0.000 01)和按方案治療(PP)根除率(88.96%對78.06%;OR=1.63,95% CI: 1.28~2.06, Plt;0.000 1)均顯著高于非多西環素方案。含多西環素方案的不良反應發生率顯著低于非多西環素方案(8.35%對15.01%;OR=0.55,95% CI: 0.42~0.71,Plt;0.000 01)。亞組分析顯示含多西環素方案的Hp根除率與含阿莫西林方案(OR=1.09,95% CI: 0.78~1.52,P=0.61)、含四環素方案(OR=0.87,95% CI: 0.33~2.26,P=0.77)相比無明顯差異,但顯著高于含克拉霉素方案(OR=2.67,95% CI: 1.84~3.88,Plt;0.000 01)和含左氧氟沙星方案(OR=2.20,95% CI: 1.50~3.22,Plt;0.000 1)。結論:含多西環素方案的Hp根除率顯著高于非多西環素方案,且不良反應發生率低,值得臨床推廣應用。

Background: Doxycycline can be used in the eradication of Helicobacter pylori (Hp) infection, but there is a lack of large sample study to confirm its efficacy and safety. Aims: To explore the efficacy and safety of doxycycline in the eradication of Hp infection. Methods: Literatures on doxycycline and other antibiotics in the eradication of Hp infection were retrieved from CNKI, Wanfang data, VIP, PubMed, Embase, Web of Science, and Cochrane Library from the date of database establishment to October 2023. Meta?analysis was conducted by RevMan 5.3 software. Results: Nineteen literatures including 3 686 patients with Hp infection were enrolled. Both intention?to?treat (ITT) eradication rate (82.51% vs. 73.65%; OR=1.72, 95% CI: 1.42?2.07, Plt;0.000 01) and per?protocol (PP) eradication rate (88.96% vs. 78.06%; OR=1.63, 95% CI: 1.28?2.06, Plt;0.000 1) of doxycycline?based regimen were significantly higher than those of non?doxycycline regimens. The adverse reaction rate of doxycycline?based regimen was significantly lower than that of non?doxycycline regimens (8.35% vs. 15.01%; OR=0.55, 95% CI: 0.42?0.71,Plt;0.000 01). Subgroup analysis showed that Hp eradication rate of doxycycline?based regimen was significantly higher than that of clarithromycin?based regimen (OR=2.67, 95% CI: 1.84?3.88, Plt;0.000 01) and levofloxacin?based regimen (OR=2.20, 95% CI: 1.50?3.22, Plt;0.000 1), however, no significant difference in Hp eradication rate was found between doxycycline?based regimen and amoxicillin?based regimen (OR=1.09, 95% CI: 0.78?1.52, P=0.61) and tetracycline?based regimen (OR=0.87, 95% CI: 0.33?2.26, P=0.77). Conclusions: The eradication rate of doxycycline?based regimen in the eradication of Hp is significantly higher than that of non?doxycycline regimens, and the adverse reaction rate is low, which is worthy of clinical application.

幽門螺桿菌(Helicobacter pylori, Hp)是慢性胃炎、消化性潰瘍和胃癌的主要致病因素,全球有超過50%的感染率[1?2]。根除Hp感染可顯著降低胃癌的發生風險[3],是胃癌防控的重要措施。然而,由于抗菌藥物的耐藥率不斷上升,導致Hp根除率逐年下降[4]。據報道,克拉霉素和左氧氟沙星在我國的耐藥率為20%~40%,甲硝唑的耐藥率高達60%~90%[5]。在我國最新制訂的指南推薦的鉍劑四聯方案中,可選用的抗菌藥物十分有限,除上述三種外,只有阿莫西林和四環素,而僅在用藥史復雜、考慮存在難以根除的情況時推薦酌情使用呋喃唑酮[6]。……
