Incidence, Course and Outcome of ABMR in Kidney Transplantation

Overview

Rationale: Despite improved patient and graft survival in renal transplant recipients, still 20% of the patients reaches end-stage renal disease within 5 years after transplantation. Antibody-mediated rejection (ABMR) is one of the major causes of early graft loss and perhaps even more important of late deterioration of graft function Objective: Evaluate the occurrence of antibody mediated rejection (ABMR) and mixed ABMR and cellular/ T-cell mediated rejection (TCMR), in patients treated with the currently prevailing immunosuppressive regimens, and relate them to outcome (graft survival, function, proteinuria, histology) Study design: Clinical cohort study. Study population: patients of \>18 years old, about to receive a post mortal of living donor renal transplant with an immunological high risk for ABMR. Main study parameters/endpoints: main study endpoints are the occurrence of ABMR, mixed ABMR/TCMR and renal function after 1 year of follow-up. The main study parameter will be mapping the immune system, including B-cells, (non-)HLA antibodies, interaction between B-cells and T follicular helper cells, and complete immune profiling.
