Abstract:
Objective To investigate the correlation between de nove anti-endothelial cell antibodies (AECA) and adverse events after renal transplantation and the effect of transplanted renal function within six months after operation.Methods The expression of AECA in serum of 85 renal transplant recipients was detected by indirect immunofluorescence assay (ⅡF) before and 1 day,3 days,7 days,15 days and 1 month after renal transplantation.The patients were divided into double positive group (AECA positive before and after surgery),single positive group (postoperative de nove AECA positive) and negative group (preoperative and postoperative AECA negative) according to AECA test results.The occurrence of adverse events in each group such as DGF,rejection,infection and so on,as well as the serum creatinine levels were recorded at each time point within six months.Results Of the 85 recipients,29 were positive for AECA,including 19 in the double positive group,10 in the single positive group,and 56 in the negative group.The incidence of rejection in single positive group (30%) was higher than that in the rest two groups (5.3% for double positive group,and 17.9% for negative group),but there was no statistically significant difference (P =0.21).The incidence of DGF in the single positive group,double positive group and negative group was 70.0%,26.3 % and 32.1 % respectively.The positive rate of the single positive group was significantly higher than that of the rest two groups (P =0.04),and the duration of DGF was significantly longer in the single positive group than that of the rest two groups (P<0.01).The incidence of infection in the single positive group,double positive group and negative group was 20.0%,21.1% and 8.9%respectively,and there was no significant difference among the three groups (P =0.31).As compared with the double positive group and the negative group,the serum creatinine level was significantly increased in the single positive group at 1st week,1st month,3rd month and 6th month after operation (P =0.02,P =0.04,P =0.04 and P =0.02 respectively).Conclusion Postoperative AECA can increase the risk of DGF,prolong the duration of DGF,and affect the recovery of renal function within 6 months after renal transplantation.
