背景

血肌酐检测加上半胱氨酸蛋白酶抑制剂C检测可改善肾小球滤过率估计值(eGFR)的准确性,但在不同的人群中,其在慢性肾脏病检出、分期和危险分类方面的作用尚不清楚。

方法

我们对11项一般人群的研究(90750名受试者)和5项有血肌酐和半胱氨酸蛋白酶抑制剂C标准化检测值的慢性肾脏病队列研究(共2960名受试者)进行了一项荟萃分析。我们比较了按照单用肌酐检测、半胱氨酸蛋白酶抑制剂C检测以及肌酐加半胱氨酸蛋白酶抑制剂C检测计算的eGFR与死亡率(15个队列中有13202例死亡)、心血管原因死亡(12个队列中有3471例死亡)、晚期肾病(7个队列中有1654例死亡)间的相关性,并评估了用半胱氨酸蛋白酶抑制剂C进行重新分类时的所改善情况。

结果

在一般人群队列中,基于半胱氨酸蛋白酶抑制剂C计算的eGFR组的eGFR < 60 ml/min/1.73 m2(体表面积)的患病率高于基于血肌酐计算的eGFR组(13.7% : 9.7%)。在所有eGFR类别中,根据半胱氨酸蛋白酶抑制剂C检测计算者与根据血肌酐值计算者相比,重新分类后归类于较高数值的eGFR与所有三个研究转归的危险降低相关,而重新分类后归类于较低数值的eGFR则与危险升高相关。与血肌酐相比,采用半胱氨酸蛋白酶抑制剂C重新分类后,死亡净改善值为0.23(95%可信区间〔CI〕为0.18~0.28),晚期肾病净改善值为0.10(95%CI为0.00~0.21)。在5个慢性肾脏病队列中,当同时使用血肌酐和半胱氨酸蛋白酶抑制剂C计算eGFR时,结果通常相似。

结论

单采用半胱氨酸蛋白酶抑制剂C或与肌酐联合使用,增加了eGFR与不同人群中死亡和晚期肾病危险间的相关性。
