This study examined the presence of anti-HCV antibodies in a group of 56 β-thalassemia major patients who received blood transfusions in a hospital in central Taiwan. Overall, 52% were found to be anti-HCV positive. A higher incidence of anti-HCV antibodies was found in patients who, during transfusion therapy, started receiving blood prior to routine screening for anti-HCV. A study indicated a higher seroprevalence among blood donors in Taiwan than in European countries in 1991. Differences in serum transaminase and ferritin concentrations between anti-HCV positive and negative patients were not significant. Results from 17 biopsies showed 4 histological diagnoses were consistent with CPH, 7 with CAH and 6 biopsies with hemochromatosis only.
