摘要 目的探讨血清半胱氨酸蛋白酶抑制剂C(CysC)在肾脏疾病中的应用价值。方法采用透射比浊法在OlympusAU2700自动生化分析仪上检测血清CysC的浓度,同时测定血肌酐、24h尿肌酐并计算肌酐清除率(Ccr)。统计分析血清CysC和血Cr分别与Ccr的相关性,并对血清CysC和血Cr的诊断敏感性、特异性予以比较分析。结果血清CysC与血Cr之间具有很好的正相关性(r=0.8380),血清CysC与Ccr的相关性(r=-0.6207)优于血Cr与Ccr的相关性(r=-0.5993)。在Ccr≥80ml/min的病例中有65.79%的病人血清CysC异常。结论血清CysC在诊断肾小球滤过率(GFR)方面比血肌酐具有一定的优越性,尤其在肾脏的早期损害中意义更大。
