Abstract
IntroductionThe role of lymphocyte cross-matches (LCM) remains controversial in the liver transplant field. The aim of this study was to correlate the risk for acute rejection episodes and graft survival in liver transplantation with pretransplant LCM results. Patients and MethodsWe enrolled 184 adult liver transplantation patients, excluding pediatric and second grafts. The 129 living donor and 55 deceased donor liver transplantations were divided into 2 groups: LCM (+); (n = 20) and LCM (−); (n = 164). ResultsThere were no differences in the demographic features, such as gender and recipient age, original disease, Model for End-Stage Liver Disease score, donor type, number of human leukocyte antigen mismatches, and cold ischemia times. There were no hyperacute rejection episodes in the LCM (+) group. Also, posttransplant complications such as acute rejection episode, biliary complication, or hepatic artery thrombosis were not different. Acute rejection episodes occurred in 5.0% of the LCM (+) group and 15.2% of the LCM (−) group (P = .317). Bile duct complications after transplantation arose in 20.0% of the LCM (+) group and in 32.9% of the LCM (−) group (P = .312). The 2 groups showed no difference in graft survival rate analyzed by the Kaplan–Meier method according to LCM results. ConclusionPretransplant LCM results were not associated with overall graft survival or acute rejection episodes in this study.
