title: Duration of antiviral therapy for cholestatic HCV recurrence may need to be indefinite.
abstract: Progressive liver allograft injury related to hepatitis C virus (HCV) recurrence occurs in 20% to 30% of liver transplant recipients within the first 5 years. In particular, the subset of patients who develop the severe cholestatic variant has an extremely high mortality. We report our center's experience with 7 cholestatic patients who were treated with interferon alfa-2b (3 million IU three times per week initially) in combination with ribavirin. In 4 of the 7 patients, HCV-RNA in serum became undetectable, and in an additional patient, normalization of serum bilirubin was achieved despite persistent viremia. Discontinuation of antiviral therapy by patient choice, intolerance of side effects, or occurrence of infection were followed temporally by rapid relapses of the cholestatic syndrome, allograft failure, and death. The only 2 patients alive in remission of this syndrome have been maintained on antiviral therapy for an average of 32 months. Thus, based on our experience, we recommend that duration of antiviral therapy in the subset of patients with cholestatic HCV recurrence should be indefinite.
