BACKGROUND: There are few data on genetic relation of the donor and outcomes in living donor liver transplantation (LDLT) recipients. We compared outcomes of LDLT between recipients of genetically related and unrelated donors in a large single-center series. METHODS: The study included 1372 adult, ABO-compatible, primary LDLT recipients, who received a graft from either a first-degree relative (parent, sibling, son, or daughter; n = 756) or unrelated donor (spouse or relative of the spouse; n = 616). RESULTS: The mean age of the recipients with a related donor was 50.2 ± 10.8 years compared with 47.3 ± 9.3 years for recipients with unrelated donors (P = 0.000). Chronic rejection was significantly more common in the genetically unrelated donor group than in the genetically related donor group (28 [4.5%] versus 9 [1.1%]; P = 0.000) at a mean follow-up of 37 months (15-95 months). There were no significant differences in other outcomes between the 2 groups. The 12-month and 36-month survival between the unrelated and related groups was 87.6% versus 90%, and 86.3% versus 89.7% respectively (P = 0.115). The multivariate analysis revealed genetically unrelated donors (odds ratio [OR]: 3.88, 95% confidence interval [CI]: 1.80-8.34, P = 0.001) and history of acute cellular rejection (OR: 3.39, 95% CI: 1.68-6.81, P = 0.001) as predictors of chronic rejection. CONCLUSION: Although chronic rejection was found to be more common in genetically unrelated donors, the patient survival after LDLT was similar.
