AP&T:肠易激综合征患者不能通过粪便菌群移植获得完全治愈

2020-07-08 MedSci原创 MedSci原创

肠易激综合症(IBS)与微生物的组成不良有关。本项研究旨在探讨粪便菌群移植(FMT)治疗IBS的疗效。

背景

肠易激综合症(IBS)与微生物的组成不良有关。本项研究旨在探讨粪便菌群移植(FMT)治疗IBS的疗效。

 

方法

研究人员通过结肠镜检查将49名IBS患者随机接受自体或异体FMT。主要观察终点是IBS症状严重度评分至少持续降低50分。次要结果是焦虑和抑郁水平,生活质量变化,肠道菌群和粪便水分含量,肠道菌群组成和粪便干重评估。

 

结果

两组均未达到主要终点。但是,与基线相比,治疗后12周FMT组的平均IBS症状严重度评分有短暂的降低(P= 0.01)。两组在12周时达到临床反应的患者数量没有差异。在接受FMT治疗的患者中,微生物组成发生了变化,类似于供体,粪便中的水含量与基线相比明显下降。FMT后IBS症状减轻的患者抑郁评分降低,但IBS症状减轻的安慰剂治疗患者并未降低抑郁评分。

 

结论

FMT仅能暂时缓解症状,尽管它会引起IBS患者微生物群的持续改变。因此,在临床实践中,不建议通过结肠镜检查单次输注递送的FMT作为IBS的治疗方法。
