Impact of calcineurin inhibitors on hepatitis C recurrence after liver transplantation.

Background And Aims: The aim of this retrospective study is to assess the impact of calcineurin inhibitors on hepatitis C virus recurrence following liver transplantation.

Methods: A total of 396 patients underwent liver transplantation for hepatitis C virus-induced liver disease between 1991 and 2005 at a single center. We examined the pre- and post-operative characteristics of patients who received either cyclosporine (n = 126) or tacrolimus (n = 270) as maintenance immunosuppression. In addition, we compared the postoperative course, including patient, graft and hepatitis C virus recurrence-free survival between the two groups.

Results: There were no significant differences between the two groups in either post-operative hepatitis C virus-ribonucleic acid or histological fibrosis score (performed within 6 months after transplant per protocol). The graft and patient survivals did not differ between the two groups (logrank p = 0.34 and 0.15, respectively). Histologic hepatitis C virus recurrence-free survival, however, was significantly higher in the cyclosporine group than in the tacrolimus group (55.4 vs. 30.8% at 1 year, 18.6 vs. 10.3% at 3 years, 16.7 vs. 8.1% at 5 years, p < 0.001).

Conclusions: Patients transplanted for hepatitis C virus and treated with cyclosporine versus tacrolimus may have a higher recurrence-free survival.
