Abstract:
OBJECTIVE: Panel reactive antibody (PRA) can induce acute rejection following kidney transplantation, however, it is poorly understood which PRA is more associated with rejection. Therefore, the aim of this study is to analyze the correlation between PRA and rejection by observing the change of PRA Ⅰ and PRA Ⅱ prior to and after the kidney transplantation. METHODS: Levels of PRA Ⅰ and PRA Ⅱ were observed in 100 patients received kidney transplantation at the Department of Urology, Beijing Chaoyang Hospital Affiliated to the Capital Medical University. During these 100 patients, 18 patients had PRA changes after operation. The relationship between PRA changes after kidney transplantation and acute rejection were analyzed. RESULTS: Totally 18 patients were included in the final analysis. Nine of them occurred acute rejection with obviously increased PRA Ⅱ (P=0.040), however, the PRA Ⅰ had no significant changes (P=0.707). The changes of PRA Ⅰ and PRA Ⅱ had no significance in the remaining 9 patients prior to and after kidney transplantation. The overall level of PRA increased in 7 patients, in 5 patients with increased PRA Ⅱ, 4 patients suffered acute rejection, 1 of which was renal allogreft failure; 2 cases with PRA Ⅰ increasing did not occur acute rejection. The overall level of PRA declined in 11 patients, including 5 patients with PRA Ⅱ decreased, 1 patient occurred acute rejection; 4 patients in 6 patients with PRA Ⅰ declined suffered acute rejection. CONCLUSIONS: The increased PRA Ⅱ after transplantation easily result in acute rejection, which has definite correlation to acute rejection, however, the PRA Ⅰ changes has no impact on acute rejection.
