【摘要】 目的继2004年系统评价之后,对睡前加服H2-受体拮抗剂抑制夜间酸突破的疗效和安全性进行再评价。方法计算机检索Cochrane图书馆临床对照试验资料库、MEDLINE、EMbase、中国生物医学文献数据库,手工检索8种相关中文期刊和所获文献的参考文献,全面收集全世界关于睡前加服H2-受体拮抗剂抑制夜间酸突破的临床随机对照试验,并按照Cochrane协作网的方法进行系统评价。结果仅有2篇随机对照交叉试验包括32例受试者符合纳入标准,由于这2个研究在设计及药物的剂量和疗程存在较大差别,无法进行Meta分析,仅进行定性的系统评价。这2个研究对睡前加服H2-受体拮抗剂抑制夜间酸突破的疗效没有一致性的结论。结论基于目前的证据尚不能确定睡前加服H2-受体拮抗剂能有效抑制夜间酸突破的发生,还需要大样本、高质量,且随访时间足够的随机对照试验来提供证据。更多还原

【Abstract】 Objectives To assess the effectiveness and safely of additional bedtime H2-recepor antagonists(H2RAs)in suppressing nocturnal gastric acid breakthrogh(NAB).Methods We identified eligible trials by searching The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMbase and CINAHL. We handsearched the data from the proceedings of correlated conferences, eight kinds of important Chinese fjoour rinnacllsu sainodn .r eTfheere snycsetse mofa tailcl rienvcileuwde wd atrsi aclosn. dAulcl treadn duosimngiz mede tchoondtrso rlelecdo mtrmialesn edveadl ubayt iTnhge H C2oRcAhrsa fnoer Cthoel lcaobnotrraotilo onf. NAB were eligible Results Only two randomized crossover studies including 32 participants met the inclusion criteria. Because the design, dosage and duration of the treatment were different between the studies, it was impossible to conduct Meta-analysis. There was no consistent conclusion between the two included studies in evaluating H2RAs for the control of NAB. Conclusion We can not conclude any implications for practice at this stage. Appropriately designed large-scale randomized controlled trials with long-term follow-up are needed to decide the effects of additional bedtime H2RAs in suppressing NAB.更多还原
