摘要 背景:目前众多实例和资料证实,群体反应性抗体的存在与否及该抗体的致敏程度对于是否发生排斥反应及移植物存活率的高低、移植后器官功能的实现都有着重要意义。目的:检测肾移植受者术前、术后群体反应性抗体水平,并结合患者临床排异情况,分析肾移植患者术前、术后群体反应性抗体水平与急性排斥反应的关系。设计、时间及地点:回顾性病例分析,于1998-09/2000-05在北京首都医科大学附属北京友谊医院泌尿科肾移植研究室完成。对象:选择在北京友谊医院接受肾移植的633例患者,男348例,女285例,年龄16~67岁。方法:采用美国OneLambda公司和德国Biotest公司淋巴细胞冷冻板,检测患者术前和术后一两个月内血清中的群体反应性抗体。主要观察指标:术前及术后患者群体反应性抗体水平、临床排斥反应发生情况。结果:移植前群体反应性抗体阴性591例,移植后群体反应性抗体阳性164例,61例术后发生急性排斥反应,占10.3%;移植前群体反应性抗体阳性42例,移植后30例发生了急性排斥反应,占71.4%,12例未发生急性排斥反应。肾移植术前群体反应性抗体阴性与阳性术后发生排斥反应比较差异有非常显著性意义(P<0.001);肾移植前后群体反应性抗体均为阴性患者427例,术后24例发生了急性排斥反应,占5.6%;肾移植后群体反应性抗体阳性164例,70例发生了急性排斥反应,占42.7%。肾移植前群体反应性抗体阴性与术后群体反应性抗体阳性并发生排斥反应的比较差异有非常显著性意义(P<0.001)。术前群体反应性抗体阴性和阳性与术后排异与否的相关系数为0.612,术后群体反应性抗体阴性和阳性与术后排异与否的相关系数为0.685,二者在P=0.01水平有明显相关性。结论:群体反应抗体对预测移植肾的急性排斥反应具有重要的意义。术前、术后群体反应性抗体阳性患者,术后发生急性排斥� BACKGROUND:It is confirmed that panel reactive antibody (PRA) and its immune level is closely related to rejection activation,renal survival rate and the realization of the renal function.Study addressing the relation PRA level and acute rejection has great clinical significance for forecasting acute rejection and improving the renal survival rate.OBJECTIVE:To analyze the relation of PRA and acute rejection prior to and after transplantation by detecting PRA level combined with patient rejection.DESIGN,TIME AND SETTING:Retrospectively case analysis was performed at the Affiliated Beijing Friendship Hospital of Capital University of Medical Sciences from September 1998 to May 2005.PARTICIPANTS:A total of 633 patients receiving renal transplantation were collected,including 348 males and 285 females,aged 16-67 years.METHODS:Company Lymphocyte Tray produced by One Lambda and Biotest were used for this study,serum PRA level was detected prior to and within 2 months after transplantation.MAIN OUTCOME MEASURES:Pre-and post-transplant PRA level and clinical rejection.RESULTS:Totally 591 patients were PRA negative in pre-transplant assay,and 164 patients were positive,10.32% (61/591) patients occurred acute rejection;42 patients were PRA positive in pre-transplant assay,and 71.42% (30/42) patients occurred acute rejection.The difference between PRA negative or positive and acute rejection had significance (P〈 0.001).427 patients were PRA negative in both pre-and post-transplant assay,5.6% (24/427) patients occurred acute rejection.164 patients were PRA negative in pre-transplant assay,but positive in post-transplant,42.7% (70/164) patients occurred acute rejection.The comparison of PRA negative pre-transplant and PRA positive post-transplant combined with acute rejection had difference (P〈 0.001).The correlation coefficient of pre-transplant PRA and acute rejection was 0.612,which was 0.658 between post-transplant PRA and acute rejection,there was obvious association when P=0
