SCI REP:中国慢性肾脏病患者肠道菌群的变化分析!

2017-06-06 xing.T MedSci原创

由此可见,终末期肾脏疾病患者粪便中总的细菌减少,相比于健康对照者。在终末期肾脏疾病患者粪便中细菌肠型从普雷沃菌到拟杆菌进行变化。肠道菌群与慢性肾脏病的炎症状态和肾功能有关。

近日,Scientific reports 杂志上发表了一篇研究文章,研究人员采用实时定量聚合酶链反应和高通量测序(16S核糖体RNA的V4-6区域)方法评估了中国南方地区52例终末期肾脏疾病患者和60名健康对照者之间粪便菌群的组成差异。

研究人员发现终末期肾脏疾病患者粪便中细菌总数的绝对定量明显降低(P<0.01)。在三种肠型中,健康对照者含量最为丰富的是普雷沃菌属,而终末期肾脏疾病患者粪便中最为丰富的是拟杆菌(LDA得分>4.5)。终末期肾脏疾病患者粪便中有11种细菌类群明显偏高,而健康对照者有22种细菌类群明显偏高。产生丁酸的细菌,如Roseburia、Faecalibacterium、梭状芽孢杆菌、粪球菌和普雷沃菌,在终末期肾脏疾病患者粪便中显著降低(LDA值>2)。

经典应答分析(CCA)表明胱抑素C(CysC)、肌酐和eGFR的是影响整体的微生物群落的最重要环境参数。在实时定量聚合酶链反应的定量分析中,丁酸产生菌种,如Roseburia、Faecalibacterium prausnitzii、普雷沃菌和普遍细菌与CRP和CysC呈显著负相关。

由此可见,终末期肾脏疾病患者粪便中总的细菌减少,相比于健康对照者。在终末期肾脏疾病患者粪便中细菌肠型从普雷沃菌到拟杆菌进行变化。肠道菌群与慢性肾脏病的炎症状态和肾功能有关。

Kidney Int:慢性肾脏疾病筛查是否具有成本效益?——一项来自加拿大的研究

加拿大原住居民的肾衰竭率比非原住居民的普通加拿大人高出2至4倍。因此,慢性肾脏病(CKD)的靶向筛查和治疗策略在这些人群中可能具有一定的成本效益。近期,一项发表在杂志Kidney Int上的研究旨在通过估计的肾小球滤过率和尿白蛋白肌酐比率来评估加拿大农村土着成年人的筛查和随后对CKD治疗的成本效用。同时,研究者将筛查和治疗策略与常规护理相比较,构建了一个决策分析马尔可夫模型。此项研究的主要结果是以
