【摘要】 目的 探讨含铋剂的四联疗法作为一线方案对幽门螺杆菌感染的有效性和安全性。 方法 选择2008年9月-2010年9月间137例确诊幽门螺杆菌感染的初治患者，随机分为RAC组（雷贝拉唑、阿莫西林和克拉霉素）和RBAC组（雷贝拉唑、阿莫西林、克拉霉素和枸橼酸铋钾）。经治疗7 d后比较两组根除率和不良反应发生率。 结果 RAC组和RBAC组的按方案分析根除率分别为77.6%和90.3%，意向性治疗分析根除率分别为72.6%和86.7%。RBAC组的按方案分析和意向性治疗分析根除率均高于RAC组（Plt;0.05）。不良反应发生率分别为1.6%和1.3%（Pgt;0.05）。 结论 以雷贝拉唑、阿莫西林、克拉霉素和枸橼酸铋钾为组合的四联疗法能显著提高幽门螺杆菌感染的初治成功率，不良反应少，安全有效。【Abstract】 Objective To investigate the effectiveness and safety of the quadruple therapy containing a bismuth compound for first-line Helicobacter pylori eradication treatment. Methods A total of 137 patients diagnosed to be Helicobacter pylori-positive between September 2008 and September 2010 were randomized into two groups to receive the combination of rabeprazole, amoxicillin and clarithromycin (RAC group) and the combination of rabeprazole, amoxicillin, clarithromycin and bismuth potassinm citrate (RBAC group) respectively. The efficacy and tolerance were observed after the treatment for 7 days. Results The per protocol (PP) eradication rates of Helicobacter pylori were 86.7% for RAC group and 90.3% for RBAC group (Plt;0.05), respectively. The intention-to-treat protocol (ITT) eradication rates of Helicobacter pylori were 72.6% for RAC group and 86.7% for RBAC group (Plt;0.05), respectively. The was no significant difference in the incidence of side effects between the two groups (1.6% vs. 1.3%, Pgt;0.05). Conclusion The quadruple therapy containing rabeprazole, amoxicillin, clarithromycin and bismuth potassinm citrate provides a good eradication rate of Helicobacter pylori with a good compliance when compared with the standard triple therapy schemes.
ObjectiveTo evaluate the effectiveness and side-effects of levofloxacin-based triple therapy as rescue regimen for Helicobacter pylori, and to compare it with the quadruple therapy. MethodsScience Direct, PubMed, Medline, China National Knowledge Infrastructure (CNKI), Chinese Social Sciences Citation Index (CSSCI, developed by Chongqing VIP Company), and Wanfang Database were electronically searched from January 2000 to September 2013. Randomized controlled trials (RCT) were focused on the eradication rate and adverse effects of levofloxacin-based regimens and generally recommended quadruple therapy after failure to eradicate Helicobacter pylori for one or more times. Two reviewers independently screened studies according to exclusion and inclusion criteria, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.0 software. ResultsFourteen literatures involving 1 402 patients were included. Meta-analysis showed that the levofloxacin-based group was better than the quadruple therapy group [RR=1.16, 95%CI (1.04, 1.30), P=0.009]. In addition, the adverse effects of levofloxacin group was less than the quadruple therapy group[OR=0.44, 95%CI (0.24, 0.81), P=0.008]. ConclusionAfter the failure of eradication of Helicobacter pylori, levofloxacin-based rescue regimen is more effective and better tolerated than the generally recommended quadruple therapy.
