Kidney int:慢性心衰患者的肾功能可以动态地预测临床结果!

肾功能不全是慢性心力衰竭(CHF)的重要组成部分,但对其单一评估并不能充分反映发生不良的临床结局之前,CHF无临床表现的进展。

近期,一项发表在杂志Kidney int上的研究调查例263例稳定型CHF患者的肾小球和肾小管标记物的时间演变过程,并确定了在临床沉默期,患者的特异性进展是否能动态预测临床结果。

研究者们确定了临床结果(因心力衰竭住院、心源性死亡、左心室辅助装置置入和心脏移植的复合终点)与标记水平、斜线和轨迹下面积的相关风险。在每位患者中,使用重复测量的肾小球标志物:肌酐/估计的肾小球滤过率(eGFR),半胱氨酸蛋白酶抑制剂C(CysC)和肾小管标志物:尿N-乙酰-β-D-氨基葡萄糖苷酶(NAG)和肾损伤分子(KIM)-1,血浆和尿中性粒细胞明胶酶相关脂质运载蛋白(NGAL)评估轨迹。

在为期2.2年的随访中,平均每个病人收集了8个尿液和9个血浆样本。所有肾小球标志物预测终点(每增加20%eGFR,单变量HR[95%置信区间]:肌酐:1.18 [1.07-1.31],CysC:2.41 [1.81-3.41],每降低20%eGFR:1.13 [1.05- 1.23])。肾小管标志物NAG和KIM-1也预测了终点(NAG:1.06 [1.01-1.11]和KIM-1:1.08 [1.04-1.11])。斜率越大,预测强度越大(肌酐:1.57 [1.39-1.84],CysC:1.76 [1.52-2.09],eGFR:1.59 [1.37-1.90],NAG:1.26 [1.11-1.44]和KIM-1:1.64[1.38-2.05])。经过多变量临床特征调整后,这种相关性仍然存在。

此项研究表明:在CHF无临床表现疾病的进展期间,肾小球和肾小管功能也发生来恶化,但不是同时发生。因此,这些肾脏标记物的特异性进展可以动态地预测CHF患者的临床结果。
