JCI Insight:肠道菌群精准诊断肝硬化

2018-04-02 小通 生物通

根据弗吉尼亚联邦大学(VCU)最新发表的一篇《JCI Insight》,肠道微生物可能是高度准确地预测肝硬化患者是否应住院治疗的一个重要指标。


根据弗吉尼亚联邦大学(VCU)最新发表的一篇《JCI Insight》,肠道微生物可能是高度准确地预测肝硬化患者是否应住院治疗的一个重要指标。

根据美国国立卫生研究院酒精滥用和酒精中毒国家研究所报道,在全球范围内,肝硬化(cirrhosis)是导致住院率和死亡率增加的主要原因之一。患肝硬化后应该住院治疗还是在家静养服药?

“肝硬化住院治疗非常昂贵,”文章一作、VCU医学院内科学教员以及Hunter Holmes McGuire VA医学中心医师Jasmohan Bajaj说。“然而,临床诊断现状却捉襟见肘。任何能帮助患者预测住院可能性的方法都值得去了解。”

Bajaj和来自George Mason大学的同事认为,由于炎症与感染关系密切,因此肠道菌群中的致病细菌和非致病细菌的相对丰度可能是准确预测患者是否需要住院的关联指标。

“致病细菌是肝硬化或肥胖患者的其中一个主要炎症来源,患者需要住院往往因为体内炎症和器官衰竭非常严重,所以我们开始探索肠道微生物以寻找引起炎性激增的感染源变化。”

研究人员根据肝硬化相关并发症(肾功能不全和感染)将VCU医学中心和McGuire VA医学中心的肝硬化患者分类,然后分别进行标准血常规预测和肠道微生物DNA、RNA分析,结果显示在预测住院时间方面,后者比单独的标准血常规检验评分更有效。DNA分析鉴定死的和活的细菌种类,RNA分析鉴定最活跃的微生物种类。研究人员发现,DNA和RNA分析在鉴定益生菌方面结果类似,但是,不同患者组群的致病菌检测结果不同。

研究小组正准备与北美研究中心联合进行多中心试验,以进一步证实肠道菌群分子生物学检测在肝硬化结果预测中的有效性。
