Meta analysis of the efficacy of probiotics for constipation in Parkinson's disease
-
摘要: 目的 系统评价益生菌制剂治疗帕金森病(PD)相关便秘的临床疗效。方法 检索PubMed、Web of Science、Cochrane Library、Clinical Trials、Google Scholar、中国知网、维普及万方数据库,建库至2023年9月发表的PD相关便秘的随机对照试验(RCTs),通过文献筛选、评价、提取资料后,运用RevMan 5.3软件进行meta分析。结果 最终纳入7篇RCTs,共536例PD相关便秘患者。meta分析结果显示:与对照组比较,益生菌制剂可增加PD便秘患者的排便次数(SMD=1.03,95%CI:0.58~1.48,P<0.000 01,I2=79%),改善粪便性状(SMD=0.49,95%CI:0.31~0.67,P<0.000 01,I2=0),降低口服泻药使用频率(SMD=-0.63,95%CI:-1.09~-0.17,P=0.007,I2=0),提高便秘相关生活质量(SMD=-12.54,95%CI:-15.21~-9.86,P<0.000 01,I2=0),并改善PD相关焦虑抑郁评分,但对PD运动症状(UPDRS-Ⅲ)改善不明显(SMD=-0.93,95%CI:-1.94~0.07,P=0.07,I2=35%)。结论 益生菌制剂可改善PD相关便秘症状以及便秘相关生活质量,但仍需要高质量大样本RCTs进一步验证。Abstract: Objective To systematically evaluate the clinical efficacy of probiotics in the treatment of constipation in Parkinson's disease.Methods We searched PubMed, Web of Science, Cochrane Library, Clinical Trials, Google Scholar, CNKI, VIP, and WanFang database for randomized controlled trials(RCTs) of constipation in Parkinson's disease(PD) up to September 2023. After literature screening, evaluation, and data extraction, we conducted meta-analysis using RevMan 5.3 software.Results Finally, seven RCTs were included, with a total of 536 PD patients with constipation. The meta-analysis results showed that compared with the control group, probiotics significantly increased the frequency of bowel movements in PD related constipation patients(SMD=1.03, 95%CI: 0.58 to 1.48, P < 0.000 01, I2=79%), improved the stool consistency(SMD=0.49, 95%CI: 0.31 to 0.67, P < 0.000 01, I2=0), reduced the frequency of using oral laxatives(SMD=-0.63, 95%CI: -1.09 to -0.17, P=0.007, I2=0), improved the quality of life related to constipation(SMD=-12.54, 95%CI: -15.21 to -9.86, P < 0.000 01, I2=0). Probiotics also remarkably improved PD related anxiety and depression scores but did not improve PD motor symptoms(UPDRS-Ⅲ)(SMD=-0.93, 95%CI: -1.94 to 0.07, P=0.07, I2=35%).Conclusion Probiotics can alleviate symptoms of constipation in PD patients and improve the quality of life related to constipation, but further validation with high-quality and large sample size RCTs is still needed.
