Immunization Anti HLA in the Liver Transplant Recipients (DSATH)

Anti HLA alloimmunization against the donor evaluated by the detection of anti-donor specific antibodies (DSA) is an underestimated factor in liver transplantation and may contribute to dysfunction and graft loss , especially among candidates for retransplantation, that have major immunization. This study will analyzed immunization markers at the time of liver retransplantation and systematically in patients follow-up. This will allow to characterize the histological lesions due to humoral immunization, to establish further investigations and to adapt early immunosuppressive therapy.
