10天序贯疗法与标准三联疗法治疗幽门螺杆菌感染荟萃分析

目的系统地评价10天序贯疗法能否获得比标准三联疗法更高的H．pylori根除率，以及两种方案之间发生副反应的差异。方法利用中英文检索词检索相关电子数据库，根据纳入标准入选了比较10天序贯疗法与标准三联疗法的幽门螺杆菌根除率的随机临床试验。提取患者基本资料、研究质量、H．pylori根除率和副作用的发生率等相关数据。针对于10天序贯疗法和7天或10天标准三联疗法的H．pylori根除率和副作用的发生率，计算相应的RR和95％可信区间。运用漏斗图评价出版偏倚。结果Meta分析纳入了10项随机对照研究，共2855例患者。10天序贯疗法明显优于7天或10天标准三联疗法，总的H．pylori根除率分别为93．5％、75．9％和79．4％，RR为1．23（95％CI=1．19—1．28）和1．16（95％CI：1．10—1．23）。无论是溃疡性消化不良患者还是非溃疡性消化不良患者，10天序贯疗法都能获得更高的H．pylori根除率，RR分别为1．16（95％CI=1．10—1．23）和1．26（95％CI=1．19—1．33）；针对克拉霉素耐药患者，10天序贯疗法的有效H．pylori根除率也高于标准三联疗法（75．9％vs32．7％），RR为2．18（95％CI=1．43—3．34）。然而两种方案副作用的发生率无明显差别（RR=1．00，95％CI=0．97—1．03）。结论10天序贯疗法明显优于7天或10天标准三联疗法,副作用无明显增加。

序贯疗法根除幽门螺杆菌感染

序贯疗法是目前欧洲MaastrichtⅣ共识意见中推荐的幽门螺杆菌(Hp)感染的一线经验性根除方案之一,其根除率、耐受性及安全性均较令人满意,但国内缺乏相关研究及应用经验。此文对目前国际上应用序贯疗法根除Hp感染的相关研究作一综述。     

序贯疗法补救根除幽门螺杆菌感染的疗效观察

序贯疗法与三联疗法根除幽门螺杆菌感染疗效比较

幽门螺杆菌（Hp）感染是慢性活动性胃炎、消化性溃疡的重要病因,国际癌症研究机构早在1994年即将Hp列为人类第一类致癌因子,并明确其为胃癌的危险因素。尽管国际上推荐的一些Hp根除方案的根除率达到或超过90％,但随着抗生素的广泛应用,传统的以质子泵抑制剂（PPI）或铋剂为基础的三联疗法对Hp的根除率已不彻底。因此,使用有效抗生素,合理调整Hp根除治疗方案非常重要。2008年1月～2009年10月,我院采用序贯疗法治疗慢性胃炎、消化性溃疡并Hp感染患者,并与采用传统三联疗法治疗者进行比较。现报告如下。

Azithromycin-containing versus standard triple therapy for Helicobacterpylori eradication： A meta-analysis

AIM: To evaluate whether adding azithromycin to firstline Helicobacter pylori (H pylori ) eradication improved eradication and reduced side effects. METHODS: Eligible articles were identified by searches of electronic databases. We included all randomized trials that compared azithromycin-containing with standard triple-therapy regimens for first-line treatment of H pylori infection. Statistical analysis was performed with Review Manager 5.0.10. Sub-analyses were also performed.RESULTS: We identified 14 randomized trials (1431 patients). Pooled H pylori eradication rates were 72.01% (95% CI: 58.09%-85.93%) and 69.78% (95% CI: 66.47%-73.09%) for patients with or without azithromycin by intention-to-treat analysis, and the odds ratio (OR) was 1.17 (95% CI: 0.64-2.14). The occurrence of side effects differed significantly and was 15.81% (95% CI: 12.50%-19.12%) and 25.20% (95% CI: 21.44%-28.96%) for treatment with or without azithromycin, respectively, and the summary OR was 0.58 (95% CI: 0.41-0.82). Furthermore, the azithromycin-containing group had a lower occurrence of diarrhea, nausea and taste disturbance. CONCLUSION: Our review suggests that azithromycincontaining triple-therapy regimens could be equally effective in eradication of H pylori compared with standard first-line triple-therapy regimens.     

Sequential therapy versus standard triple-drug therapy for Helicobacter pylori eradication: A randomized study

Background

Antimicrobial resistance has decreased eradication rates for Helicobacter pylori infection worldwide. A sequential treatment schedule has been reported to be effective, but studies published to date were performed in Italy. We undertook this study to determine whether these results could be replicated in India.

Methods

A randomized, open-labeled, prospective controlled trial comparing sequential vs. standard triple-drug therapy was carried out at Lokmanya Tilak Municipal General Hospital, Mumbai. Two hundred and thirty-one patients with dyspepsia were randomized to a 10-day sequential regimen (40 mg of pantoprazole, 1 g of amoxicillin, each administered twice daily for the first 5 days, followed by 40 mg of pantoprazole, 500 mg of clarithromycin, and 500 mg of tinidazole, each administered twice daily for the remaining 5 days) or to standard 14-day therapy (40 mg of pantoprazole, 500 mg of clarithromycin, and 1 g of amoxicillin, each administered twice daily).

Results

The eradication rate achieved with the sequential regimen was significantly greater than that obtained with the triple therapy. Per-protocol eradication rate of sequential therapy was 92.4 % (95 % CI 85.8–96.1 %) vs. 81.8 % (95 % CI 73.9–87.8 %) (p?=?0.027) for standard drug therapy. Intention-to-treat eradication rates were 88.2 % (95 % CI 80.9–93.0 %) vs. 79.1 % (95 % CI 71.1–85.4 %), p?=?0.029, respectively. The incidence of major and minor side effects between therapy groups was not significantly different (14.6 % in the triple therapy group vs. 23.5 % in sequential group, p?=?0.12). Follow up was incomplete in 3.3 % and 4.7 % patients in standard and sequential therapy groups, respectively. Sequential therapy includes one additional antibiotic (tinidazole) that is not contained in standard therapy.

Conclusions

Sequential therapy was significantly better than standard therapy for eradicating H. pylori infection.     

含莫西沙星的三联疗法作为根除幽门螺杆菌一线方案的Meta分析

目的 综合分析含莫西沙星的三联方案作为根除幽门螺杆菌（Hp）一线方案的疗效.方法 检索比较含莫西沙星的三联方案和标准三联方案根除幽门螺杆菌治疗的随机对照临床试验,进行荟萃分析.结果 共有7项随机对照试验符合人选标准,共纳入899例患者.基于意向治疗分析的结果显示含莫西沙星组Hp根除率为85.7%,标准治疗组为74.7%,差异有显著性（P〈0.0001）.基于按符合方案集分析的结果显示含莫西沙星组Hp根除率为86.5%,标准治疗组为76.1%,差异有显著性（P〈0.0001）.进一步行敏感性分析显示,纳入高质量研究、中文研究、疗程7天的研究和不同疾病谱的研究时结果均未出现变化.结论 含莫西沙星的三联治疗方案有较高的Hp根除率,且优于目前的标准治疗方案,可以作为根除Hp的一线治疗方案.     

Dual versus triple therapy in eradication of Helicobacter pylori

BACKGROUND/AIMS: Duodenal ulcers should be treated by eradication of Helicobacter pylori. This study compared the efficacy of a proton pump inhibitor together with one or two antibiotics in eradication therapy. METHODOLOGY: 177 patients who were H. pylori positive were randomized to receive 14 days of either: lansoprazole 30 mg bd and amoxicillin 1 g bd (LA), omeprazole 20 mg bd and amoxicillin 1 g bd (OA) or lansoprazole 30 mg bd, amoxicillin 1 g bd and clarithromycin 500 mg bd (LAC). The efficacy was assessed at four weeks and at six months after the end of treatment. Biopsies were taken for culture and bacterial sensitivity testing at inclusion and at four weeks after the end of treatment. RESULTS: 149 patients were evaluated for efficacy. The eradication rate was significantly higher in LAC (96%) compared to LA (51%) and OA (64%) treatments (P < 0.001). At baseline 17%, 21% and 19% of the patients in the LA, OA and LAC groups, respectively, were resistant to metronidazole and only one patient was resistant to clarithromycin. Post-treatment, four patients had acquired metronidazole resistance. CONCLUSIONS: LAC is more effective than LA and OA for eradication of H. pylori in duodenal ulcer disease.     

10天序贯和标准三联疗法根除幽门螺杆菌的疗效比较

目的评估新的序贯疗法对幽门螺杆菌的根除率。方法我院91例慢性胃炎患者纳入研究。幽门螺杆菌感染由组织学、尿素酶和尿素酶呼气试验评估。序贯疗法包括埃索美拉唑、阿莫西林治疗5天,随后以埃索美拉唑、克拉霉素和替硝唑治疗另外的5天。对照组标准三联疗法包括埃索美拉唑、阿莫西林和克拉霉素治疗10天。幽门螺杆菌的根除率以意向性分析(ITT)和完成治疗分析(PP)表示。根除疗效的判断根据治疗后6周的尿素酶呼气试验结果。结果序贯治疗对慢性胃炎患者的幽门螺杆菌感染获得86.36%(95%CI=81.19%-91.53%)和92.68%(95%CI=88.62%-96.74%)的根除率,但是和10天标准三联治疗相比较差异没有统计学意义。结论序贯治疗能获得较高的幽门螺杆菌根除率,但和10天标准三联治疗比较未获得显著的统计学差异。
