摘要：
目的:利用血清半胱氨酸蛋白酶抑制剂C(Cys-C)、肌酐(Cr),尿液肾损伤因子1(KIM-1)评价使用万古霉素老年患者致急性肾损伤,为临床药师协助临床医师制定个体化给药方案提供理论依据.方法:回顾性收集2016年7月~2017年5月入住我院ICU使用万古霉素治疗耐甲氧西林金黄色葡萄球菌(MRSA)血流感染的老年患者48例,统计万古霉素治疗前和用药后6,12,24,48h患者血清Cys-C、Cr,尿KIM-1检测数据.根据AKI诊断标准将患者分为AKI组和对照组.比较两组患者用药后血清Cr、Cys-C、尿KIM-1水平差异,绘制受试者工作特征曲线(ROC)评价Cys-C、KIM-1的临床诊断价值.结果:使用万古霉素48 h后,有32例(66.67%)患者发生AKI.与对照组相比,AKI组患者血清Cr于用药后48 h、Cys-C于用药后24 h、尿KIM-1于用药后12 h开始显著上升(P<0.05).利用血清Cys-C、Cr及尿KIM-1分别进行AKI诊断时,在用药后12 h诊断发生AKI的人数差异有统计学意义(P<0.05).ROC曲线分析结果显示:尿KIM-1曲线下面积(AUC 0.797,95%可信区间:0.647~0.947),血清Cys-C曲线下面积(AUC 0.582,95%可信区间:0.364~0.799).结论:与传统肾损标志物Cr相比,血清Cys-C及尿KIM-1可更早地预判老年患者肾功能情况,为肾功能的早期评估提供可靠依据,有助于临床药师利用有效指标协助临床医师及时调整老年患者万古霉素给药方案.%Objective:To evaluate acute kidney injure ( AKI) induced by vancomycin in elderly patients by the determination of serum C ( Cys-C) , creatinine ( Cr) and urine kidney damage factor 1 ( KIM-1 ) in order to provide theoretical evidence for clinical pharmacists helping clinicians make individualized dosage regimen. Methods:A retrospective collection of 48 elderly patients admitted to ICU in our hospital from July 2016 to May 2017 treated with vancomycin for MRSA blood flow infection was carried out. The basic values of serum Cys-C, Cr and urine KIM-1 were determined before the treatment of vancomycin and 6, 12, 24h and 48h after the drug use. According to the AKI diagnostic criteria, the patients were divided into the AKI experimental group and the control group. The se-rum Cr, Cys-C and urine KIM-1 were compared between the groups after the drug use and the clinical diagnostic values of Cys-C and KIM-1 were assessed by the working characteristic curve ROC of the subjects. Results:Totally 32 cases (66. 67%) of patients were with AKI induced by vancomycin at 48h after the administration. Compared with that of the control group, the serum Cr, Cys-C and u-rine KIM-1 was significantly higher respectively at 48h, 24h and 12h after the drug use in the AKI experimental group, and the differ-ences between the groups were statistically significant(P<0. 05). Using serum Cys-C, Cr and urine KIM-1 as the AKI diagnosis, the number of AKI at 12h after the drug use had statistically significant difference (P<0. 05). The results of ROC curve analysis showed that the area under the KIM-1 curve of urine was 0. 797 with 95% confidence interval of 0. 647-0. 947), and the area under the serum Cys-c curve was 0. 582 with 95% confidence interval of 0. 364-0. 799. Conclusion: Compared with the traditional kidney damage markers Cr, serum Cys-C and urine KIM-1 can earlier predict renal function in elderly patients to provide reliable basis for early evalu-ation of renal function, which is helpful to the timely adjustment of vancomycin dosage regimen by clinicians assisted by clinical phar-macists for elderly patients.
