Graft Rejection or Tolerance Affected by Serial Change of Anti-donor Lymphocyte Antibody After Liver Transplantation
Liver is an organ that is well-known for its immune tolerant capacity. However, there were still controversial issues about the impact of immunologic challenge after liver transplantation on the graft function. Different results of graft function affected by immunologic factors such as pre-transplant panel reactive antibody (PRA) status, pre-transplant positive lymphocyte cross match (LCM), or post-transplant circulating donor specific antibody (DSA) has been reported according to individual institutes. There was no trial for presenting anti-donor lymphocyte antibody change after liver transplantation.
The investigators designed this study to analyze the correlation between pre- and post-transplant immune status (PRA, LCM), and graft survival / rejection episode. Also, the investigators will find aspects of anti-donor lymphocyte antibody change after liver transplantation.
Liver Transplant Rejection

|Official Title:||Graft Rejection or Tolerance Affected by Serial Change of Anti-donor Lymphocyte Antibody After Liver Transplantation|
- incidence of acute rejection [ Time Frame: Time point when patients are diagnosed acute rejection ] [ Designated as safety issue: No ]We designed to analyze the aspects of acute rejection between anti-donor lymphocyte antibody change liver transplantation.
- correlation between pre- and post-transplant immune status (PRA, LCM), and graft survival [ Time Frame: at 7 day, 14 day, 21 day after transplantation and at 3 month, 6 month after transplantation ] [ Designated as safety issue: No ]We designed this study to analyze the correlation between pre- and post-transplant immune status (PRA, LCM), and graft survival / rejection episode.

Liver transplant recipients
Recipients who will undergo liver transplantation during study period
Study Design: Target study population is forty patients who will undergo liver transplantation for 1 year in YUHS. Pediatric and early mortality cases will be excluded. Blood sample will be collected at pre-transplant period, post-transplant 7, 14, 21 day, 3 month and 6 month.
