Popis: Kidney transplantation is the treatment of choice in patients with an end-stage kidney disease (ESKD). Before kidney transplantation, it is important to assess the patient's immunological risk, which has an impact on graft survival after kidney transplantation. Human leukocyte antigens (HLA), also known as major histocompatibility complex (MHC) are responsible for the rejection of genetically different tissue by recognizing and distinguishing foreign proteins from self-proteins. HLA-typing and anti-HLA antibody screening are crucial to determine the donor/recipient mismatching. Diagnostic methods used for anti-HLA antibody detection and immunological risk assessment are complement-dependent cytotoxicity (CDC), flow cytometry crossmatch (FCXM), bead-based assays (Luminex technology), calculated panel-reactive antibody (cPRA), and algorithm “predicted Indirectly Recognizable HLA Epitopes“ (PIRCHE). The aim of these diagnostic tests is to minimize HLA mismatch between the donor and the recipient and prevent an early graft failure by the presence of HLA donor-specific antibodies (DSA).
