Gastroenterology: 粪菌移植治疗艰难梭菌感染的患者长期安全性的风险

2021-05-14 MedSci原创 MedSci原创

粪便微生物菌群移植(FMT)是治疗艰难梭菌感染(CDI)的一种高效的方法,最近的临床指南也建议可以使用FMT治疗抗生素无法解决的复发性CDI。

      粪便微生物菌群移植(FMT)是治疗艰难梭菌感染(CDI)的一种高效的方法,最近的临床指南也建议可以使用FMT治疗抗生素无法解决的复发性CDI。随着FMT在临床实践中的广泛使用,人们对FMT的短期和长期安全性开始担忧。最近,在由于肠病原体传播导致严重不良事件(AE)的被报道后,美国食品药品监督管理局(FDA)发出了FMT 的安全警告。在一项针对259名参与者的前瞻性研究中,有106名患者报告在FMT后的一个月内至少出现一种症状,最常见的是非CDI腹泻。因此,本项研究旨在对FMT对于CDI复发的短期和长期安全性进行科学地分析。

 

      这是一项前瞻性的研究,研究时间跨度为2012年9月至2018年6月,研究人员对CDI复发的接受FMT治疗的患者进行了统计分析。人口统计学和合并症的数据是从病历中提取的。所有患者在接受FMT后1周,1个月,6个月,1年(短期)和≥2年(长期)均进行临床随访,并在每个时间点记录症状。使用年龄(每10年增加),性别,调查时间和合并症建立了不良事件的多变量logistic回归模型进行统计学分析。

 

       总共有609例患者接受了FMT治疗。中位年龄为56岁,女性占64.8%,患有炎症性肠病(IBD)的为22.8%。短期随访(n = 609)后研究人员发现,有超过60%的患者存在腹泻,19%-33%的患者出现便秘。在多变量分析中,IBD疾病,依赖透析的肾脏疾病和多种FMT移植的患者出现腹泻的风险较高;女性便秘的风险较高,而IBD的女性则较低(P <.05)。对于长期随访(n = 447)的患者。总体而言,总共报告了73例CDI复发:有13%患者出现胃肠道症状,10%的患者体重增加。FMT后感染复发的中位时间为29个月。

       本项研究证实难治性CDI患者接受FMT治疗安全性是很高的,而且感染传播的风险很低。
