特异性单克隆与非特异性多克隆抗体荧光免疫偏振法测定肾移植病人全血环孢素浓度的比较及肝功能对血药浓度的影响

目的 观察特异性单克隆抗体与非特异性多克隆抗血清荧光免疫偏振法测定肾移植病人全血环孢素浓度的差异及肝功能对血药浓度的影响。方法 对36位肾移植术后病人的84份环孢素(CsA)血样同时用特异性单克隆(MAFPIA)和非特异性多克隆抗体(PAFPIA)荧光免疫偏振分析法进行测定。对两种方法测得的数值进行统计学处理。结果 MAFPIA与PAFPIA之间有较好的线性关泉(相关系数为0. 8947),两者的测得值具统计学显著性差异。肝功能异常的患者PAFPIA测得值显著大于MAFPIA测得值。与肝功能正常患者相比有明显差异,且两者的回归曲线参数均有明显不同。结论 对 CsA血药浓度测定应采用特异性高的方法。

Determination of cyclosporine A by the fluorescence polar-ization immunoassay methods in renal transplant recipients and the influence of hepatic function on CsA concentration

Aim This study was to investigate the influence of specific and nonspecific detecting methods on CsA blood concentration in renal transplanting patients, and to observe the effects of hepatic function on CsA concentration. Methods Eighty-four whole blood specimens from 36 renal transplant recipients who had received cyclosporine (CsA) were measured with MAFPIA and PAFPIA. Results Linear regression analysis showed that there was a better rela tionship between PAFPIA and MAFPIA (r = 0.8974). Values of PAFPIA in patients with reduced hepatic function was significantly higher than those of MAFPIA. Both regression curve parameters differed greatly from each other. It is suggested that therapeutic drug monitoring for CsA should be performed with the specific method.
