The aim is to evaluate the impact of donor specific HLA alloantibodies (DSA) on all-cause mortality and re-transplantation, early allograft dysfunction, acute and chronic rejection, fibrosis, vascular, and biliary complications. Furthermore, all biopsies will be C4d stained. The hypothesizes is that donor specific HLA alloantibodies facilitate an immune mediated damage to the liver allograft that impairs function and lead to various complications. The investigators will do a prospective blinded multicenter cohort study in the Scandiatransplant organ sharing organization region. Both preformed, persistent, and de novo donor specific HLA alloantibodies will studied. Blood samples will be taken immediately prior to transplantation, and 14 days, 3 months, and 1 year after transplantation. All liver biopsies performed during the study period will be evaluated for a humoral component and blood samples will be obtained prior to liver biopsies to investigate the presence of DSA. Investigations will be fully blinded for the treatment responsible doctors.
