title: Antidonor antibody in patients receiving ABO-identical and HLA-mismatched living donor liver transplants: effect on survival.
abstract: We retrospectively determined the correlation of results of lymphocyte crossmatch tests by direct complement-dependent cytotoxicity, to the outcomes of 585 consecutive ABO-identical and human leukocyte antigen (HLA)-mismatched living donor liver transplants (LDLTs) (male:female=276:309; median age, 18 years). Crossmatch test results were positive in 14 recipients (2.4%). Patient survival at eight years in the crossmatch-positive group was significantly lower than in the crossmatch-negative group (positive group, 56.3%; negative group, 77.6%; P=0.014). The survival at five years of the crossmatch-positive group was significantly lower than the negative group in both older recipients (>or=18 years of age: positive group, 41.7%; negative group, 76.4%; P=0.0065), and female recipients (positive group, 37.5%; negative group, 81.9%; P=3.3x10). We conclude that antidonor antibodies have adverse effects on the clinical outcome of LDLTs, and that being female and/or older aged (>or=18 years of age) are risk factors for LDLT.
