Background: Hepatitis C virus (HCV) infection is common worldwide. The treatment typically involves a combination of interferon-alpha (IFN-α) and ribavirin (RBV) therapy; however, the use of IFN-α is well documented to be associated with thyroid disease, the most common autoimmune disorder associated with IFN-α. Aim: The aim of the present study was to know the prevalence of thyroid abnormality in the HCV-positive patients on IFN and antiviral therapy. Materials and Methods: Fifty known HCV positive patients were enrolled for the study. All the patients were on IFN (3 million unit subcutaneously 3 times/week) and antiviral therapy (oral RBV 1000–1200 mg/day). Thyroid function tests were performed first at the start of treatment and then after 12 weeks of treatment. Results: 13 (26%) of the patients were found to develop hypothyroidism, and 1 (2%) patient developed hyperthyroidism in the course of 12 weeks therapy. Conclusion: HCV patients on IFN and antiviral therapy have an effect on the thyroid gland, so these patients should be regularly screened for thyroid disorders and appropriately treated to maintain euthyroid status.
