摘　　要：目的观察稳定期肾移植受者由普通剂型他克莫司(Tac)转换为缓释剂型Tac后对移植肾功能的影响。方法回顾性分析山西省第二人民医院2011年12月至2019年6月由普通剂型Tac转换为缓释剂型Tac的83例稳定期肾移植受者,随访12~36个月,同时匹配83例继续服用普通剂型Tac的稳定期肾移植受者作为对照组。观察稳定期肾移植受者由普通剂型Tac转换为缓释剂型Tac后肾功能、谷值浓度个体内变异度(IPV)及依从性的变化、排斥反应的发生率及移植肾和移植受者的存活率。结果普通剂型Tac转换为缓释剂型Tac时间为移植后(42.76±30.50)个月,转换后24个月血清肌酐(SCr)明显低于转换前(P=0.013),估算肾小球滤过率(eGFR)明显高于转换前(P=0.005)。试验组较对照组在转换后36个月SCr明显降低(P=0.017),eGFR明显增高(P=0.038)。试验组转换前免疫抑制剂治疗障碍量表(ITBS)得分为(20.23±2.89)分,转换后为(17.63±3.08)分(P=0.000);Tac每日剂量转换前是(2.09±0.84)mg,转换后为(2.10±0.83)mg;Tac谷值浓度转换前为(7.22±2.84)ng/mL,转换后显著降低,人/肾均健康存活。结论稳定期肾移植受者由普通剂型Tac转换为缓释剂型Tac肾功能保持稳定且较普通剂型Tac相对更好,依从性明显改善,谷值浓度个体内变异度明显降低,长期服用的临床疗效和安全性良好。Objective To observe the effect of conversion from immediate-release tacrolimus(Tac)to extended-release Tac on kidney function in stable kidney transplant recipients.Methods 83 stable kidney transplant recipients who were converted from immediate-release Tac to extended-release Tac in the second people's hospital of Shanxi province from December 2011 to June 2019 were followed up for 12-36 months,and 83 stable kidney transplant recipients who continued to take immediate-release Tac were selected as control group.The changes of kidney function indexes,Tac trough concentration intra-patient variability(IPV)and compliance,the incidence of rejection and the survival rate of grafts and recipients were observed after the conversion from immediate-release Tac to extended-release Tac in stable kidney transplant recipients.Results The conversion time from immediate-release Tac to extended-release Tac was(42.76±30.50)months after transplantation.At 24 months after conversion,the serum creatinine(SCr)was significantly lower than that before conversion(P=0.013),and the estimated glomerular filtration rate(eGFR)was significantly higher than that before conversion(P=0.005).In the experimental group,the SCr was significantly lower than that of the control group at 36 months after conversion(P=0.017),eGFR was significantly higher than that of the control group(P=0.038).In the experimental group,the score of Immunosuppressant Therapy Barrier Scale(ITBS)was(20.23±2.89)before conversion and(17.63±3.08)after conversion(P=0.000).The daily dose of Tac was(2.09±0.84)mg before conversion and(2.10±0.83)mg after conversion.The trough concentration of Tac before conversion was(7.22±2.84)ng/mL,which reduced significantly after conversion.No rejection occurred after conversion,and the recipients/grafts survived healthily during the follow-up period.Conclusions After conversion from immediate-release Tac to extended-release Tac in stable kidney transplant recipients,the kidney function is stable and better than that of before conversion
