雷帕霉素与他克莫司治疗慢性移植肾肾病

目的 探讨低剂量免疫抑制剂组合治疗慢性移植肾肾病的临床效果. 方法慢性移植肾肾病患者31例,均经临床及部分移植肾穿刺病理证实.术后免疫抑制方案为他克莫司(FK506)、吗替麦考酚酯(MMF)、泼尼松(Pred)三联免疫抑制治疗.调整免疫抑制剂方案为雷帕霉素(RAPA)加低剂量FK506+MMF+Pred四联方案.根据血药浓度、血常规、肝肾功能调整免疫抑制剂用量.监测血压、急性排斥反应发生率、血肌酐、肌酐清除率(GFR)、24 h尿蛋白定量.结果 31例随访12个月.28例患者SCr由治疗前(300±21)μmol/L,治疗后降至(215±38)μmol/L,GFR由治疗前(42.54±2.95)ml·s-1/1.73 m2升至(49.98±3.05)ml·s-1/1.73 m2;治疗前后SCr、GFR差异均有统计学意义(P＜0.05).3例SCr 416～464μmol/L者治疗后SCr仍进行性上升,恢复血液透析治疗.30例24 h尿蛋白定量＜0.8 g者应用RAPA后尿蛋白量并不增加,1例24 h蛋白尿由0.95g升至1.29g.人/肾存活率为100%(31/31)、90.3%(28/31).治疗过程中主要不良反应为全血细胞减少和高脂血症.结论 慢性移植肾肾病患者SCr 167～320μmol/L,24 h蛋白尿定量＜0.8 g,采用RAPA加低剂量FK506+MMF+Pred治疗安全、有效.

Rapamune and Tacrolimus improve renal function significantly in chronic allograft nephropathy

Objective To discuss the efficacy of application combination Of minimal immunosuppressive drugs in chronic allograft nephropathy after renal transplantation. Methods Data were drawn from the First Hospital of Tsinghua University.From September 1,2004 to July 1,2006,31 cadaver kidney transplantations were performed using triple immunosuppression with tacrolimus(n=31)and MMF plus steroids before using new strategy.The new strategy is Rapamycin+tacrolimus+MMF+Prednisone.The serum ereatinine,GFR(ml/min/1.73 m2)and 24-hours urine protein before and after 12 months of using lOW dose combination of calcineurin inhibitors,MMF,Rapamune,Predsone and Q80 were recorded.During this time,the concentration of tacrolimus,rapamune were monitored as well. Results After 12 months follow-up,the serum creatinine of 28 patients were decreased from(300±21)μmol/L to(215±38)μmol/L.GFR(ml/min/1.73m2)was elevated from 42.54±2.95 to 49.98±3.05.Three patients whose serum creatinine was 416-464μmol/L had to take hemodialysis.The 24-hours urine protein(g)of 31 patients below 0.8 g did not increase urine protein during follow-up.One patient's 24-hours urine protein(g)increased from 0.95 to 1.29.The patient and graft survival rate was 100%(31/31),90.3%(28/31)respectively.The rapamune main side effect was hyperlipidemia. Conclusions Rapamune and low dose Tacrolimus+Myeophenolate Mofetil+Corticosteroid could be a safe treatment.It may improve renal function in chronic allograft nephropathy.
