BACKGROUND: HCV infection and transfusional iron overload in Thalassemic patients may result in liver disease. HCV treatment in Thalassemia has raised safety concerns. AIM: Estimate effectiveness and tolerability of interferon-based therapy in HCV-infected Thalassemic patients. MATERIAL AND METHODS: Over a 12-year period, consecutive patients with β Thalassemia major (TM) and chronic hepatitis C received treatment. Liver biopsy, HCV-RNA and genotyping were performed beforehand. Sustained virological response (SVR) was defined as negative HCV-RNA 6 months post-treatment. Forty eight patients (26 M-22 F, mean age 39.8) were enrolled. Twenty nine patients were treated with conventional interferon alpha (IFNa) for 48 weeks (group A). Nineteen patients (10 naïve-9 previously IFNa experienced) received pegylated interferon (PEGIFN) (group B). RESULTS: HCV-1 was found in 44%, HCV-2 in 14%, HCV-3 in 23% and HCV-4 in 19%. Group A: ten patients (38.5%) achieved SVR, 2 (7.5%) relapsed and 17 (54%) were non responders. Group B: five (28%) achieved SVR, 8 (44%) relapsed and 6 (28%) never responded. High HCV-RNA levels, genotype 1 and advanced liver fibrosis were independently associated with no response. Four patients (3 treated with IFNα, 1 with PEG-IFN) had to discontinue treatment due to complications. CONCLUSIONS: The response rate of IFN monotherapy in multi-transfused, HCV-infected Thalassemic patients is not inferior to that in non-multitransfused patients. IFNa administration is well-tolerated and should be recommended as initial treatment schedule in this setting.
