JCC: 克罗恩病的粪便微生物群动力学及其与病程的关系

2019-10-03 不详 MedSci原创

有研究表明,微生物变化与克罗恩病[CD]的疾病活动有关,因此,本项研究旨在探究了随着时间变化或稳定病程的成年CD患者的粪便微生物群的差异。

背景
有研究表明,微生物变化与克罗恩病[CD]的疾病活动有关,因此,本项研究旨在探究了随着时间变化或稳定病程的成年CD患者的粪便微生物群的差异。

方法
研究人员收集了15个健康对照者[HCs],35个缓解期并维持缓解期的CD患者(RR)以及22个缓解期及随后加重期CD患者的粪便样本。通过16S rRNA [V4]基因测序评估微生物组成。

结果
与HCs相比,CD患者的微生物丰富度较低[ p = 0.0002],多样性[ p = 0.005]也较低。此外,除HCs以外,一部分患者的微生物群落结构以微生物多样性低和费氏杆菌含量高为特征。与具有“健康外观”微生物菌群的患者相比,该集群中的患者在长期病程方面没有差异。随着病程的延长,RR和RA患者的微生物丰富度和多样性没有变化。尽管与HCs相比,RR和RA患者的微生物群落结构随着时间的推移不稳定,但是在患者组之间没有观察到差异[ p = 0.17]。

结论
CD患者中微生物群组成和稳定性的改变与疾病活动或长期病程无关。
