OBJECTIVE: The aim of this study was to determine the response to treatment with interferon-alpha (IFN-alpha) in patients with chronic hepatitis C who had end-stage renal disease (ESRD) or hemophilia in Singapore. METHODS: Treatment-naive hepatitis patients with ESRD or hemophilia were given IFN-alpha(2a) 3 million units three times per week for 12 months in an open-label study. Hepatitis C virus RNA was determined before treatment, at the end of treatment and 6 months thereafter. Regular clinical examinations including blood counts and biochemistry were carried out during and after the treatment. RESULTS: Nine consecutive patients with ESRD (8 men and 1 woman) and 6 consecutive male patients with hemophilia, with a mean age of 43 and 40 years, received treatment. Patients in both groups were predominantly infected with hepatitis C virus genotype 1 and had significant cytopenia affecting all three cell lines during the treatment; only 1 patient developed serious neutropenia, temporarily demanding a reduction of his IFN dose. Biochemical and virological responses at the end of treatment were accomplished by 8 of the 9 (89%) patients with ESRD and 4 of the 6 (67%) patients with hemophilia; however, 1 patient with ESRD and 2 with hemophilia relapsed after the treatment. Four of the 7 patients with ESRD who had sustained virological response underwent successful kidney transplantation later on. CONCLUSION: Monotherapy with IFN-alpha for 12 months is safe for treatment of the patients with chronic hepatitis C who had ESRD or those with hemophilia. A higher sustained virological response rate was observed in patients with ESRD than in those with hemophilia (78 vs. 33%).
