Abstract:
BACKGROUND: It remains poorly understood regarding the incidence of panel reactive antibody (PRA) production and its influence to renal function and long-term survival in China. OBJECTIVE: To investigate the incidence of PRA after living renal transplant, so as to provide reference for predicting long-term renal survival. METHODS: A total of 54 patients who received living renal transplantation in Beijing Friendship Hospital from March 2005 and October 2007, were selected. PRA, serum creatinine and urea nitrogen level were detected 1-2 years after transplantation. PRA assay was conducted using One Lambda ELISA HLA-Ⅰ +Ⅱ antigen tray. Serum creatinine and urea nitrogen data were offered by clinical laboratory. RESULTS AND CONCLUSION: A total of 12.96% (7/54) patients showed PRA positive after transplantation, with HLA-Ⅱ antibody positive in 6 patients, and HLA-Ⅰ + Ⅱ antibody positive in 1 patient. In these 7 patients, 6 underwent primary transplantation, and PRA negative before transplantation; 1 patient underwent transplantation for the second time, and HLA-Ⅱ antibody positive before transplantation. Creatine and urea nitrogen level were abnormal in 1 patient with HLA-Ⅰ + ⅠⅡ antibody positive and 2 patients with HLA-Ⅱ antibody highly positive. Creatinine and urea nitrogen levels were normal in 4 patients with low level HLA-Ⅱ antibody. Results show that HLA-Ⅰ +Ⅱ antibody positive and high level HLA-Ⅱ antibody affect renal function in living renal recipients, but low level HLA-Ⅱ antibody has no effect on renal function.
