Immunosuppression affects the rate of recurrent primary biliary cirrhosis after liver transplantation



Identifying the risk factors associated with recurrence of primary biliary cirrhosis after liver transplantation may affect immunosuppression and increase understanding of the pathogenesis. Four hundred eighty-five patients with PBC were followed for a median of 79 months after transplantation; histological evidence of recurrence was found in 23%. On multivariate analysis, the only risk factor identified with recurrence was the type of calcineurin inhibitor used. The odds ratio for recurrence on tacrolimus was 2.73 (95% confidence interval: 1.84–4.10) compared with cyclosporine. For those receiving cyclosporine, the median time to recurrence was 123 months and for those on tacrolimus 62 months (P < .001). Reasons for this difference between the 2 calcineurin inhibitors are not clear. (Liver Transpl 2004;10:488–491.)
