Liver transplantation for primary biliary cirrhosis: influence of primary immunosuppression on survival.

INTRODUCTION: Liver transplantation is the only established curative therapy for end-stage primary biliary cirrhosis (PBC). However, the influence of primary immunosuppression on long-term patient and graft survival is still controversial.

PATIENTS AND METHODS: Among 1372 patients who underwent liver transplantation from April 1989 to January 2001, 95 (6.9%) suffered from PBC. The primary immunosuppression consisted of cyclosporine (CyA; n = 56) and tacrolimus (FK; n = 39).

RESULTS: The median survival of all PBC patients at 5 years was 92% and at 10 years, 90%. There was no difference between the two primary immunosuppression agents. Seven patients died, including five in the cyclosporine group (median = 25 months) and two in the tacrolimus cohort (median = 37 months). One CyA patient group died due to PBC recurrence. Seven patients underwent retransplantation without any difference in primary immunosuppression (CyA 7%; FK 10%). Fifty patients developed an acute rejection episode (CyA 57%; FK 46%); 2 patients, chronic rejection (CyA 2%; FK 4%). Fifty-five patients developed AMA titers after liver transplantation (CyA 66%; FK 46%). Patients presented cyclosporine-based regimens showed significantly (P = .001) more side effects.

CONCLUSION: Long-term follow-up after liver transplantation for PBC shows excellent organ and patient survival. The choice of the primary immunsuppressant had no significant influence on patient survival, PBC-related graft loss, or development of acute or chronic rejection episodes.
