摘要 目的探讨低剂量钙调磷酸酶抑制剂(CNI)联合西罗莫司(SRL)的四联免疫抑制方案治疗慢性移植肾肾病(CAN)的有效性及安全性。方法回顾性分析43例使用以CNI为基础的三联免疫抑制剂方案(CsA/Tac+MMF/Aza+Pred)的患者,在经移植肾活检诊断为CAN后加用SRL,同时下调CNI类药物的使用剂量。观察患者联合治疗12个月后的血肌酐、肾小球滤过率(使用Cockcroft-Gault公式计算)、总胆固醇及三酰甘油的变化。根据联合治疗前24 h尿蛋白是否大于500 mg,分为A组(24 h尿蛋白≤500 mg/24 h,n=26)和B组(24 h尿蛋白>500 mg/24 h,n=17);比较两组联合治疗后血肌酐及肾小球滤过率变化幅度的差异;以及分别观察两组治疗前后24 h尿蛋白的变化。结果联合治疗12个月后,43例患者血肌酐及肾小球滤过率改善明显(P<0.05),总胆固醇及三酰甘油变化不明显(P>0.05)。A组患者血肌酐及肾小球滤过率改善均较B组明显(P<0.05);A组治疗12个月后24 h尿蛋白无显著升高(P>0.05),而B组24 h尿蛋白明显升高(P<0.05)。结论低剂量CNI联合SRL的四联免疫抑制方案可以在一定程度上改善CAN患者的移植肾功能,在24 h尿蛋白小于500 mg/24 h的患者中效果更明显,且在对蛋白尿的影响方面相对安全;但是在24 h尿蛋白大于500 mg/24 h的患者中有加重蛋白尿的风险。
