JASN:不同肾小球肾炎类型对肾脏抑制临床结局有何影响?

2017-02-14 xing.T MedSci原创

不同GN类型临床结局不同的原因以及引起终末期肾病的原因仍需进一步的研究。

有关各种类型的肾小球肾炎(GN)患者肾脏移植预后的差异的研究较少。近日,肾脏病领域权威杂志Journal of the American Society of Nephrology发表一篇研究文章,通过美国肾脏数据系统,研究人员确定了所有首次(1996-2011年期间)肾脏移植成年(≥18年)的终末期肾病接受者,这些参与者的终末期肾病归因于六种GN类型中的一种或两种对照肾脏疾病。

研究人员采用Cox比例风险回归计算了死亡、全因移植失败以及死亡原因以外的移植失败(竞争风险框架)的风险比。

在纳入研究的32131例GN患者中,IgA肾病(IgAN)患者的死亡率最低,并且IgAN或血管炎患者的移植失败率最低。对病人和移植相关因素进行调整后,相比于IgAN(参考)患者,FSGS、膜性肾病、膜增殖性GN、狼疮性肾炎以及血管炎发生死亡的风险比(95%可信区间)分别为1.57(1.43至1.72)、1.52(1.34至1.72)、1.76(1.55至2.01),1.82(1.63到2.02)和1.56(1.34至1.81);死亡原因以外的移植失败的风险比分别为1.20(1.12至1.28)、1.27(1.14至1.41)、1.50(1.36至1.66)、1.11(1.02至1.20)和0.94(0.81至1.09)。考虑到外部对照组,并且与IgAN相比,常染色体显性遗传性多囊肾病(ADPKD)和糖尿病肾病死亡率风险比更高 [分别为1.22(1.12至1.34)和2.57(2.35至2.82)],但是ADPKD导致的死亡原因以外的移植失败的风险比较低[0.85(0.79至0.91)]。

由此可见,不同GN类型临床结局不同的原因以及引起终末期肾病的原因仍需进一步的研究。
