血清胱抑素C是一个自称是优于血浆肌酐肾功能的新指标。我们评估了这两个参数在年轻的血压正常的受试者(ñ= 12; 6名男性,平均年龄25 + / - 2年)和老人的正常血压和高血压患者(N = 41; 19位男性,平均年龄67 + / - 6岁) ,在所有个人使用菊粉清除(C(IN))技术测定肾小球滤过率(GFR)。与年轻的受试者相比,平均GFR为温和,但显着(P <0.001),老年人(年轻,119 + / - 11 mL/min/1.73米(2)对老人,104 + / - 12毫升/分钟/ 1.73米(2))。平均血浆肌酐浓度在两组相同(年轻,0.93 + / - 0.11毫克/升对老年人,0.93 + / - 0.10毫克/升,P <0.90)。平均血清胱抑素C浓度显着(P <0.001),老年人(0.84 + / - 0.10毫克/升)与年轻受试者相比(0.69 + / - 0.08毫克/升)。在所有,但一个老人的主题,血浆肌酐浓度是血浆肌酐浓度95%的信心区间在年轻的学科内。11 41老年受试者(27%)有较低的95%置信区间,分别和12 41老年受试者(29%)小于一般财务报告准则,血清胱抑素C浓度较年轻的学科上95%的置信区间。之间的血清胱抑素C浓度和C(IN)(R = -0.65,P <0.001)的相关性大大高于血浆肌酐浓度和C(中)之间的相关(r = -0.30,P <0.02)。血清胱抑素C的浓度比血浆肌酐浓度的标记是肾功能不全(即GFR降低),至少在血浆肌酐浓度在正常范围内的老年人。
