Abstract:
Objective To investigate the value of anti-human leukocyte antigen (HLA)antibody level detected by Luminex testing in predicting clinical prognosis of renal transplantation recipients. Methods A total of 1 105 patients scheduled to undergo renal transplantation (354 successfully undergoing renal transplantation)in the 181st Hospital of People's Liberation Army from June 2013 to November 2015 were selected. The serum samples were collected from 1 923 cases before and after renal transplantation. The positive rate and fluorescent intensity of anti-HLA antibody were detected by Luminex testing before and after renal transplantation. The renal function of recipients was also evaluated after renal transplantation. Results Prior to renal transplantation,51.0%(546/1 071)of serum samples were positive for anti-HLA antibody,including 26.0%(279/1 071)positive for anti-HLAⅠantibody,24.9%(267/1 071)positive for anti-HLAⅡantibody and 11.4% (122/1 071 )positive for both anti-HLA Ⅰ and anti-HLA Ⅱ antibodies. Among 354 patients undergoing renal transplantation,59 (17%)were positive for anti-HLA antibody after renal transplantation,including 25 (4 newly positive after surgery)positive for anti-HLAⅠantibody,15 (1 newly positive after surgery)positive for anti-HLAⅡantibody and 19 (4 newly positive after surgery)positive for both anti-HLA Ⅰ and anti-HLA Ⅱ antibodies. During subsequent follow-up,13 patients positive for anti-HLAⅠantibody,5 positive for anti-HLAⅡantibody and 1 1 positive for both anti-HLA Ⅰ and anti-HLA Ⅱ antibodies developed transplant kidney dysfunction. All patients newly positive for anti-HLA antibody after renal transplantation presented with transplant kidney dysfunction. Conclusions Luminex testing can perform dynamic detection of the positive rate of anti-HLA antibody,which is important in predicting clinical prognosis of recipients after renal transplantation.
