Adult beta-thalassemic patients with chronic hepatitis C: long-term efficacy of alpha-IFN treatment.
Background: The purpose of this study was to assess the effectiveness of alpha-IFN in adult beta-thalassemic patients with chronic hepatitis C. After a long-term follow-up, we describe the special pattern of biochemical and virological response of thalassemics. Methods: Thirty-two anti-HCV-positive adult thalassemic patients (19 female and 13 male, mean age 23.4+/-5.5 years) with biopsy-proven chronic hepatitis were treated with IFN alpha2beta at a dose of 3 MU thrice weekly for 6-12 months. The patients were followed up until 45-62 months after the end of treatment. Results: A sustained response was obtained in eight patients (25%). Only two of the sustained responders (25%) normalized ALT during the first 3 months of treatment. Both early and late biochemical responders cleared HCV-RNA after 6 months of treatment. Eight patients (25%) responded with ALT normalization within 2 months of treatment but relapsed soon after stopping IFN. Sixteen patients (50%) did not respond to IFN. Conclusion: The response rate in multitransfused thalassemic patients with chronic hepatitis C treated with IFN is similar to that in non-thalassemics. The special feature of thalassemics is that early biochemical response does not predict a sustained response; on the contrary, patients who normalize ALT after 6 months of IFN treatment usually do not relapse.
