Objective To evaluate the clinical effectiveness of helicobacter pylori (HP) eradication in treating functional dyspepsia (FD) patients with HP infection. Methods The randomized controlled trials (RCTs) about HP eradication vs. general treatment for FD patients published by April, 2012 were searched in the following databases: CBM, CNKI, WanFang Data, PubMed, Ovid, EMbase and The Cochrane Library (Issue 1, 2012). According to the inclusion and exclusion criteria, two reviewers independently screened studies, extracted data, and evaluated the methodological quality. Then the meta-analysis was conducted using RevMan 5.1 software. Results The total 14 RCTs were included. Among all 2 665 patients involved in, 1 339 were in the treatment group, while the other 1 326 were in the control group. The results of meta-analysis showed that HP eradication was superior to general treatment for FD patients in clinical effects (RR=3.90, 95%CI 3.08 to 4.94, Plt;0.000 01), symptomatic score (WMD=−1.68, 95%CI −1.88 to −1.47, Plt;0.000 01), and improvement of upper abdominal pain (RR=2.84, 95%CI 2.02 to 3.99, Plt;0.000 01). Conclusion With obviously clinical effects, HP eradication can decrease the symptomatic score of dyspepsia, and especially improve upper abdominal pain. For the quality and quantity limitations of the included studies, more well-designed and double blind RCTs are required to further prove this conclusion.
目的 分析幽门螺杆菌(Helicobacter pylori, HP)根除治疗失败相关因素，为有效根除Hp提供建议和决策。 方法 对2005年5月-2008年12月经胃镜检查确诊的慢性胃炎或消化性溃疡，且Hp检测阳性并行含质子泵抑制剂三联或四联治疗的患者103例进行研究。治疗结束至少4周后，用14C呼气试验评估Hp是否成功根除，根据测试结果分为治疗失败组33例及治疗成功组70例。运用统一标准的调查表对每位患者进行相关因素调查，就调查表所涉及的因素在根除失败组与成功组间采用单因素及多因素Logistic回归进行分析。 结果 通过单因素分析依从性和饮酒在两组之间有统计学意义(P＜0.05)。Logistic多因素分析发现，依从性差是根除失败的独立危险因素。 结论 依从性差是治疗失败十分重要的影响因素。
目的:观察两种常用一线根除幽门螺杆菌(H.pylori)三联方案在本地区(成都市)的疗效。方法:纳入70例诊断为消化性溃疡、慢性糜烂性胃炎、慢性萎缩性胃炎伴H.pylori感染的患者。随机分为A、B两组。A组采用埃索美拉唑(E)20 mg bid+克拉霉素(C)500 mg bid+甲硝唑(M)400 mg bid,B组采用E 20 mg bid+ C 500 mg bid+阿莫西林(A)1.0g bid治疗,疗程7天。H.pylori根除失败者以1周四联方案:E 20 mg bid+胶体次枸櫞酸铋(B)220 mg bid+呋喃唑酮100 mg bid+ A1.0g bid治疗,观察疗效。结果:64例完成实验。三联方案H.pylori根除率:A组62.5%,B组84.4%,有显著差异(Plt;0.05)。二线四联方案根除率94.1%。结论:ECA方案H.pylori根除率明显高于ECM方案,可能更适合于本地区根除H.pylori的一线治疗,EBFA方案作为二线治疗具有较高疗效。
