Preemptive therapy with pegylated interferon alpha-2b and ribavirin after liver transplantation for hepatitis C cirrhosis.
We present our results of preemptive treatment with pegylated interferon and ribavirin after liver transplantation for hepatitis C cirrhosis.


METHODS
Between September 2001 and August 2002, four patients were started on combination therapy with pegylated interferon-alpha-2b (1microg/kg weekly) and ribavirin (400-1000 mg/d) 3 to 4 weeks' posttransplant. Treatment was continued for 6 (genotype 3a, 2 patients) or 12 (genotype 1b, 2 patients) months. Virologic and biochemical responses as well as side effects were evaluated.


RESULTS
Two patients (genotype 3a) became HCV (hepatitis C virus)-RNA negative after 3 months of therapy and are persistently negative 20 and 14 months after end of therapy. One patient (genotype 1b) became HCV-RNA negative 6 months after start of treatment, but therapy had to be withdrawn after 9 months owing to fatigue and suspicion of angina pectoris. One patient who was later retransplanted because of hepatic artery thrombosis discontinued therapy after 2.5 months owing to anemia, leukopenia, and no signs of HCV-RNA reduction. Interestingly, two of the responders were nonresponders prior to liver transplant. Median ALT levels at start of therapy were 98 U/L (r = 60-126) and 12 months later 40 U/L (r = 24-58) (n = 4). No rejection episode was detected.


CONCLUSIONS
In patients liver-transplanted due to HCV-cirrhosis, combination therapy with pegylated interferon and ribavirin can be effective and safe in the early posttransplant period, thus preventing recurrent hepatitis C.
