摘要 目的:探讨半血清胱蛋白酶抑制素C(CysC)对行脑血管造影术患者发生对比剂肾病(CIN)的早期诊断价值。方法:急性缺血性脑卒中使用非离子型造影剂行脑动脉造影以及脑血管介入术患者293例作为研究对象;分别于术前24h内,以及术后8h、24h、48h采血,检测血清肌酐(SCr)、胱蛋白酶抑制素C(CysC)水平。根据患者在造影后48h内是否发生CIN,分为CIN组和非CIN组。比较CIN组和非CIN组各个时间点CysC和SCr水平的变化;应用受试者工作曲线(ROC)比较两种指标对CIN的早期诊断价值。结果:CIN的发生率为8.53%,CIN组造影后24h血浆CysC浓度已明显升高,而血清SCr浓度于造影后48h升高。应用ROC比较发现,CysC曲线下面积优于SCr(0.827vs 0.613,P<0.05),以CysC 1.65mg/L作为诊断CIN的标准,其敏感性为94.7%,特异性为86.9%。结论:造影后24h的血浆CysC浓度对CIN的早期诊断有一定的价值,较SCr更为理想。
