Abstract
Thyroid dysfunction is a known complication of interferon treatment in patients with hepatitis C virus (HCV) infection. Other uncommon endocrine complications have been reported during the treatment of viral hepatitis with IFN-α, such as hypopituitarism. A 54-year-old female patient with chronic hepatitis C began treatment with pegylated (PEG)-IFN-α 2a 180 μg/week plus ribavirin 1000 mg/day. At week 20 of treatment, her routine laboratory control showed low levels of thyroid-stimulating hormone (TSH) and free serum thyroxine. This was confirmed at week 24, and other laboratory values showed low levels of adrenocorticotrophic hormone (ACTH). A T1-weighted magnetic resonance imaging scan demonstrated high intensity of the anterior pituitary gland and enhancement after intravenous administration of gadolinium. Hypophysitis with hypothalamic-pituitary dysfunction and secondary or central hypothyroidism was diagnosed on the basis of the clinical features, endocrinological assessment, immunological markers and imaging studies. Twenty-four weeks after stopping treatment, HCV RNA was negative by polymerase chain reaction and alanine aminotransferase values were below the upper limits of normal, and ACTH and thyroid values remained within the reference values. This is the first report of central hypothyroidism and hypophysitis during treatment with PEG-IFN-α plus ribavirin, and may be included in the potential list of side effects of the combination treatment.This publication has 8 references indexed in Scilit:
