| Abstract: | The factors that influence long‐term outcomes after living‐donor liver transplantation (LDLT) for primary biliary cirrhosis (PBC) are not well known. Compared with deceased‐donor transplantation, LDLT has an increased likelihood of a related donor and a decreased number of human leukocyte antigen (HLA) mismatches. To clarify the effects of donor relatedness and HLA mismatch on the outcomes after LDLT, we retrospectively analyzed 444 Japanese patients. Donors were blood relatives for 332 patients, spouses for 105, and “other” for 7. The number of HLA A‐B‐DR mismatches was none to two in 141, three in 123, and four to six in 106 patients. The 15‐year survival rate was 52.6%, and PBC recurred in 65 patients. Recipient aged 61 years or older, HLA mismatches of four or more (maximum of six), graft:recipient weight ratio less than 0.8, and husband donor were adverse indicators of patient survival. IgM 554 mg/dL or greater, donor–recipient sex mismatch, and initial immunosuppression with cyclosporine were significant risks for PBC recurrence, which did not affect patient survival. In subgroup analysis, conversion to cyclosporine from tacrolimus within 1 year diminished recurrence. Prospective studies are needed to determine the influence of pregnancy‐associated sensitization and to establish an optimal immunosuppressive regimen in LDLT patients. |
