CYP3A5~* 3基因多态性与肾移植术后环孢素肝损伤的相关性

目的:研究肾移植术后患者CYP3A5*3基因多态性对环孢素(CsA)所致肝损伤的影响。方法:采用PCR-RFLP(聚合酶链反应-限制性片段长度多态性)方法对359名肾移植患者进行CYP3A5*3基因型检测;荧光偏振免疫法检测肾移植患者CsA血浓度,根据肾移植患者发生肝脏损伤的情况分为CsA肝损伤组、其他原因肝损伤组和对照组。结果:在359名肾移植患者中,CYP3A5*3突变等位基因频率为73.5%。与对照组相比,CsA肝损伤组和其他原因肝损伤组的CYP3A5*3/*3分布频率明显增高(P<0.05或0.01),CsA肝损伤组的CYP3A5*3/*3分布频率亦明显高于其他原因肝损伤组(P<0.01)。肾移植术后1个月和3个月,CYP3A5*3/*3组和*1/*3组的CsA血谷浓度均明显高于*1/*1组(P<0.05)。术后7d、1个月、3个月、6个月,CsA肝损伤组的CsA谷浓度明显高于对照组(P<0.05或P<0.01)。Logistic回归模型显示,*3/*3基因型和术后6个月高CsA谷浓度是CsA肝损伤发生的危险因素。结论:CYP3A5*3基因多态性对肾移植患者CsA所致肝损伤有明显影响,携带*3突变基因...

Association of CYP3A5~* 3 polymorphism with cyclosporine-induced liver injury in Chinese renal transplant recipients

OBJECTIVE To investigate the effects of CYP3A5*3 genetic polymorphism on cyclosporine(CsA)-induced liver injury in Chinese renal transplant recipients.METHODS CYP3A5*3 genotype was determined by PCR followed by restriction fragment length polymorphism(RFLP) analysis in a total of 359 renal transplant recipients receiving CsA.The whole blood CsA levels of renal transplant recipients were measured by fluorescence polarization immunoassay.All the subjects were divided into CsA-induced liver injury group,non-Cs...
