Background:
Although hepatitis B virus (HBV) primarily affects hepatocytes, it has also been shown to cause complications in the skin, joints, muscles, and kidneys. Thyroid dysfunction is uncommon in cases of acute HBV infection.
Case Presentation:
In this report, we describe a case of a 46-year-old woman with incipient acute hepatitis B virus (HBV) infection who presented clinically with Graves' hyperthyroidism. She showed typical symptoms of hyperthyroidism, and laboratory tests revealed high levels of HBV DNA and alanine transaminase (ALT). The patient was not administered with antithyroid medicine or radioiodine, but she was given antiviral therapy and symptomatic treatment with propranolol. Follow-up studies showed that as the HBV DNA levels decreased, the thyroid function recovered.
Conclusion:
Graves' disease maybe an extrahepatic manifestation of acute HBV infection. Antiviral therapy is likely to be beneficial for this condition as without severe thyrotoxicosis.
