Abstract
El trasplante renal es la mejor opción terapéutica para la enfermedad renal terminal (ERT); el conocimiento del papel de los anticuerpos anti-antígeno leucocitario humano (HLA) en el rechazo a corto y largo plazo, junto con el descubrimiento de los inmunosupresores anti-calcineurínicos, ha permitido disminuir la pérdida temprana del injerto renal. Aun así, todavía existen pacientes que pierden precozmente el injerto principalmente por trombosis, habiéndose descrito anticuerpos frente a antígenos autólogos en el rechazo y pérdida del injerto a largo plazo. Sin embargo no se conoce su papel en la pérdida temprana del injerto. Objetivo: El principal objetivo de este estudio es determinar el papel de una serie de autoanticuerpos preformados y marcadores de daño endotelial en la pérdida del injerto en los primeros 6 meses post-trasplante y entre los 7 y 24 meses post-trasplante...
Kidney transplant is the best therapeutic option for end stage renal disease (ERT); the knowledge of anti-human leukocyte antigen antibodies (HLA) in graft rejection along with the discovery of anti-calcineurinic immunosupressors, has allowed the decrease of early graft loss. Nonetheless, there are patients that still lose the graft rapidly, mainly due to thrombotic events. In the other hand, there have been reported antibodies against autologous antigens associated with graft rejection and loss mainly at long-term. However, the role of these autoantibodies is not known at short-term graft loss.Objectives: The main objective is to uncover the role of a series of pre-transplant autoantibodies and an endothelial damage biomarker in kidney graft loss during the first 6 and between 7 and 24 post-transplant months...
