Liver Transplantation for Primary Biliary Cirrhosis: Results of Aggressive Corticosteroid Withdrawal

Introduction. A subset of patients with primary biliary cirrhosis (PBC) may require long-term corticosteroid (CS) therapy following liver transplantation (OLT) due to concern over the possibility of recurrence. Our center has attempted to minimize CS use in all of our OLT recipients. In this study, we review our experience in this cohort to determine (1) patient outcome including PBC recurrence following transplantation and (2) the long-term requirement for CS use in PBC patients. Methods. From 1988 to 2006, 1102 OLTs were performed in 1032 adults at the University of Colorado, of which 70 patients (6.8%) with PBC received 74 allografts. Bivariate and multivariate analyses were used to evaluate predictors of CS withdrawal. Thirteen potential predictors of CS discontinuation were considered: age, gender, body mass index (BMI), race, type of graft (cadaveric or living donor [LD]), recurrence of PBC, warm ischemia time, and immunosuppressant. Results. Overall survival at 5 years was 85%. The 1-, 5-, and 10-year recurrence-free survivals were 90%, 72%, and 54%, respectively. PBC recurred in 18 patients (25.7%). Of these, none received a second transplant due to disease recurrence. At the time of last follow-up, 73% of recipients were steroid free. Independent predictors of CS discontinuation are age (>54; P = .0059) and LD graft type (P = .0008). Conversely, cyclosporine (P = .0007), female gender (P = .0216), and BMI > 31 (P = .0306) were negatively associated with CS withdraw. Importantly, steroid discontinuation did not influence PBC recurrence. Conclusions. While long-term outcomes in PBC patients are favorable, disease recurrence can generally be managed medically without the need for a second transplant. Using an aggressive CS minimization approach, nearly three-quarters of the patients were CS free at the time of last follow-up. Increasing age and LID grafts were associated with successful CS withdraw. Conversely, cyclosporine use, female gender, and increasing BMI were associated with unsuccessful steroid discontinuation.
