摘 要:背景:肠道菌群失调在肝硬化及其并发症的发生中起重要作用。近年来益生菌制剂在肝硬化治疗中的应用引起了广泛关注。目的:评价益生菌制剂治疗肝硬化的疗效。方法:检索PubMed、SpringerLink、WileyOnlineLibrary、MEDLINE、WebofScience、TheCochraneLibrary以及CNKI、维普、万方数据库,选取关于益生菌制剂治疗肝硬化的随机对照试验(RCTs),应用RevMan5.1软件进行meta分析。二分类变量和连续变量分别采用相对危险度(RR)和加权均数差(WMD)或标准化均数差(SMD)进行评估。结果:共27项RCTs满足纳入和排除标准。与对照组相比,益生菌制剂可显著降低肝硬化患者的外周血ALT(WMD=15.08,95%CI:6.67-23.49,P=0.0004)、AST(wMD=5.24,95%CI:0.75-9.73,P:0.02)水平和血氨(sMD=0.35,95%CI:0.16-0.54,P=0.0003)、内毒素(SMD=0.75,95%CI:0.55~0.96,P〈0.00001)含量,升高血清白蛋白水平(WMD=0.97,95%CI:0.47~1.48,P=0.0001),缩短数字连接试验(NCT)反应时间(WMD=24.03,95%CI:4.06~44.00,P=0.02),降低肝性脑病(HE)(RR=0.48,95%CI:0.26~0.89,P=0.02)和自发性细菌性腹膜炎(SBP)(RR=0.53,95%CI:0.38~0.74,P=0.0002)发生率。对肝硬化合并HE的亚组分析显示,益生菌制剂可显著降低HE患者的血氨和内毒素含量。结论:益生菌制剂可明显改善肝硬化患者的临床症状和生化指标,降低HE和SBP的发生风险,对肝硬化合并HE有明显治疗作用。Background: Aheration of intestinal flora is considered playing a key role in disease progression and development of complications in liver cirrhosis. Therefore, probiotics have attracted wide attention in the treatment of liver cirrhosis. Aims: To evaluate the efficacy of probiotics in the treatment of liver cirrhosis. Methods: PubMed, Springer Link, Wiley Online Library, MEDLINE, Web of Science and The Cochrane Library, as well as CNKI, CQVIP and Wanfang Database were searched to retrieve the randomized controlled trials (RCTs) evaluating the efficacy of probiotics in treating liver cirrhosis. Meta analysis was performed by using RevMan 5.1 software. Categorical variables and continuous variables were assessed by relative risk (RR) and weighted mean difference (WMD) or standardized mean difference (SMD), respectively. Results: Twenty-seven RCTs fulfilling the inclusion and exclusion criteria were enrolled. Compared with the control group, probiotics significantly decreased peripheral levels of ALT (WMD = 15.08, 95% CI: 6.67-23.49, P = 0.000 4), AST (WMD =5.24, 95% CI: 0.75-9.73, P=0.02), ammonia (SMD =0.35, 95% CI: 0.16-0.54, P= O. 0003) and endotoxin ( SMD = 0.75, 95% CI : 0.55-0.96, P 〈 0. 000 01 ), raised serum albumin level ( WMD = 0.97, 95% CI : 0.47-1.48, P = 0. 000 1 ), shortened completion time of number connection test (NCT) (WMD = 24.03, 95% CI : 4.06-44.00, P = 0.02) , and reduced morbidities of hepatic encephalopathy (HE) ( RR = 0.48, 95% CI : 0.26- 0.89, P = 0.02) and spontaneous bacterial peritonitis (SBP) ( RR = 0.53, 95% CI: 0.38-0.74, P = 0. 000 2) in cirrhotic natients_ Suhgroun analvsis showed that nrohintics signifieantlv reduced ammonia and endotoxin levels in cirrhoticpatients complicated with HE. Conclusions: Probiotics is effective for improving clinical and biochemical parameters and decreasing risks of HE and SBP in cirrhotic patients, and is significantly beneficial for patients complicated with HE
