Background. Vascular endothelial cells are primary targets for injury during both cellular and humoral allograft rejection (AR). In cardiac transplantation, the role of humoral immunity in mediating AR has not been extensively characterized. Methods. Antibodies against human vascular endothelial cells (AECA) were measured using a cellular ELISA developed from human umbilical vein endothelial cells in 80 consecutive patients after cardiac transplantation. The aim was to determine the incidence of AECA formation after transplantation and their association with different types of AR, graft survival, and development of cardiac allograft vasculopathy (CAV). At least eight serum samples obtained from each patient were examined for AECA and an endomyocardial biopsy was performed at regular intervals during the first year after transplantation. Results. Of the 80 patients examined, 31 were AECA (+) and 49 patients were AECA (-). There were no significant differences between the AECA (+) and (-) groups when examined for age, sex, and pretransplantation ischemia time. A significant correlation was found between the presence of AECA and humoral AR (P |
