根除幽门螺杆菌治疗功能性消化不良的临床证据

目的为临床实践提供有关功能性消化不良(FD)根除幽门螺杆菌(HP)治疗的循证医学证据。方法根据HP感染与FD的关系和HP根除治疗在治疗FD中的作用两个临床问题,检索VIP(1989～2005)、CBMdisc(1978～2005)、MEDLINE (1978～2006)以及Cochrane图书馆(2005年第4期)的系统评价,Meta分析,随机对照试验和临床指南,评价HP感染与FD的关系和HP根除治疗在治疗FD中的作用,为临床实践提供最佳的循证医学证据。结果共纳入2篇系统评价、1篇Meta分析和11篇随机对照试验。现有证据显示:FD患者HP感染率高于无症状者,但HP感染在FD发生中的作用还有待流行病学研究及病理生理研究的证据证实。HP根除治疗HP阳性FD,可以减缓部分消化不良患者的症状,但对改善患者生活质量无明显意义。HP根除治疗的成本-效益价值主要取决于患者希望明确诊断的愿望,还没有很好地证据显示需要对HP阳性FD都行HP根除治疗。结论基于目前的临床证据,我们认为对FD是否行HP根除治疗应根据患者的情况,做到个体化,对一些常规治疗差的患者可考虑采用HP根除治疗。

Clinical Evidence of H Pylori Eradication in Functional Dyspepsia

Objective To provide evidence of the role of helicobacter pylori eradication in the treatment of functional dyspepsia. Methods We searched VIP, CBMdisc, MEDLINE and The Cochrane Library for systematic reviews, meta-analysis, randomized controlled trials and clinical guidelines involving helicobacter pylori and functional dyspepsia, so as to provide the best evidence for clinical practice. Results We included two systematic reviews, one meta-analysis and eleven randomized controlled trials. The evidence identified showed that helicobacter pylori infection was more prevalent in functional dyspepsia than in asymptomatic patients, but the effect of H pylori infection in the pathogenesis of functional dyspepsia remained controversial. H pylori eradication therapy had a relatively weak effect in H pylori positive functional dyspepsia. An economic model suggested that this modest benefit may still be cost-effective, but more studies are needed to assess this. Conclusion According to the current evidence, it can be concluded that helicobacter pylori eradication for the treatment of functional dyspepsia should be individualized.
