BACKGROUND: Transfusion-acquired hepatitis C virus (HCV) remains an important problem among patients with thalassemia. In this study, we evaluated the natural history of post-transfusional hepatitis C in thalassemia major, paying special attention to spontaneous viral clearance, to factors influencing the chronicity rate and fibrosis progression.
DESIGN AND METHODS: A prospective study to evaluate the incidence and etiology of transfusion-related hepatitis was started in 1980. In patients who developed hepatitis C, HCV RNA, ALT, and ferritin were measured over time. The correlation between interleukin-28B gene polymorphisms and viral clearance was also analyzed.
RESULTS: Seventy-three of 135 patients (62.2%) acquired HCV. An extended follow-up (22 to 30 yr) with HCV RNA assessment was available in 52 patients. Of them, 23 (44.2%) cleared the virus. The proportion of IL-28B genotypes was different between the subjects who cleared the virus and the subjects who did not. Fibrosis progression was similar in HCV RNA-positive and HCV RNA-negative patients. Liver iron was the only factor associated with the fibrosis.
CONCLUSIONS: In thalassemia patients with HCV infection, liver iron does not play a major role in influencing the chronicity rate, whereas it is significantly associated with the fibrosis.
