Primary biliary cholangitis (PBC) is diagnosed mainly in female individuals, and risk factors for PBC recurrence (rPBC) after liver transplantation (LT) from cadaveric donors have been reported. We conducted a retrospective multicenter study of rPBC in female patients after living‐donor LT (LDLT). A total of 388 female patients undergoing LDLT for end‐stage PBC were enrolled, and the effects of preoperative and operative factors were evaluated. Postoperative factors were evaluated in 312 patients who survived for more than 1 year post‐LDLT. rPBC was defined as abnormal hepatic enzyme levels with typical histological findings in liver biopsies. Fifty‐eight patients (14.9%) developed rPBC with a median of 4.6 (0.8‐14.5) years post‐LT. Cox hazard analysis ( P  < 0.05) showed that younger recipient age (hazard ratio, 0.95; 95% confidence interval, 0.920‐0.982), shorter operative time (1.00; 0.995‐0.999), higher serum immunoglobulin M level (1.00; 1.001‐1.002), donor sex mismatch (2.45; 1.268‐4.736), human leukocyte antigen B60 (2.56; 1.336‐4.921) and DR8 (1.98; 1.134‐3.448), and initial treatment with cyclosporine A (3.14; 1.602‐6.138) were significantly associated with rPBC. The frequencies of Child‐Turcotte‐Pugh class C (0.46; 0.274‐0.775), the model of end‐stage liver disease score (0.96; 0.914‐0.998), and updated Mayo risk score (1.02; 1.005‐1.033) were significantly lower in rPBC. Posttransplantation use of steroids decreased and that of antimetabolites increased the frequency of rPBC. Conclusion : The timing of LT, recipient conditions, donor characteristics, and immunosuppressive medications may be associated with rPBC in LT recipients.
