Gut:克罗恩病的微生物标志

2017-02-21 xing.T MedSci原创

虽然UC和CD有许多共同的流行病学、免疫学、治疗和临床的特征,该研究结果表明,它们在肠道微生物层面上是IBD的两种不同亚型。这是第一次提出了采用微生物标志来区分CD患者和非CD患者。

十多年的微生物研究已将炎症性肠病(IBD)与遗传易感者的肠道微生物群落改变联系在一起。然而,成年IBD患者肠道菌群失调情况在现已发表的研究结果中并不一致,因此并不能确定Crohn's病(CD)和溃疡性结肠炎(UC)的微生物特征性标志物。近日,消化病领域权威杂志Gut上发表了一篇研究文章,研究人员旨在通过一个纵向研究比较CD患者、UC患者和非IBD患者的粪便微生物。

研究人员分析了来自于四个国家(西班牙、比利时、英国和德国)的2045例非IBD患者和IBD患者的粪便样本,研究人员所用方法为16S rRNA测序方法,他们分析了含有1亿1500万个序列的总数据集。

在西班牙人群队列中,研究人员发现CD患者相比于UC患者发生菌群失调更加明显,如菌群多样性减少、不稳定的微生物群落增加,并且发现8群微生物可能作为CD特定的微生物标志。对整个队列进行检测,这些微生物标志总的敏感性达到了80%,相比于健康对照者、厌食症患者、IBS患者和UC患者,其检测CD的特异性分别为94%、94%、89%和91%。

虽然UC和CD有许多共同的流行病学、免疫学、治疗和临床的特征,该研究结果表明,它们在肠道微生物层面上是IBD的两种不同亚型。这是第一次提出了采用微生物标志来区分CD患者和非CD患者。
