Adv Sci: 肠道微生物组可以鉴别单相抑郁症和双相抑郁症

2020-03-31 网络 网络

双相情感障碍(BD)和重度抑郁症(MDD)是两种常见的严重精神疾病,正确的诊断和治疗方案至关重要。但两者的症状有很多相似之处,且目前主要依靠临床病史和症状,误诊率较高,因此,BD和MDD的鉴别研究十分

双相情感障碍(BD)和重度抑郁症(MDD)是两种常见的严重精神疾病,正确的诊断和治疗方案至关重要。但两者的症状有很多相似之处,且目前主要依靠临床病史和症状,误诊率较高,因此,BD和MDD的鉴别研究十分重要。

最近发现,肠道微生物群的改变与这两种情绪障碍有关,MDD和BD的共同和差异的微生物特征不清楚。本实验使用16SrRNA测序方法,比较165名MDD患者,217名BD患者和217名健康对照者(HCs)的微生物组成。

结果发现,三组样本的微生物组成存在差异。与HCs相比,MDD患者的拟杆菌科(Bacteroidaceae)的分类单元(operational taxonomic units, OTUs)发生改变,BD患者的Lachnospiraceae、Prevotellaceae、Ruminococcaceae等科的共变OTUs紊乱。此外,确定了26个差异OTUs可以区分MDD,BD和HCs人群,26个微生物标志物中有4个与MDD或BD的疾病严重程度相关。

在MDD中确定了与BD和HCs不同的肠道微生物组成,并提供了一个新的肠道微生物组特征的标记板,用于鉴别MDD和BD。
