The risk of thyroid dysfunction induced by Interferon (IFN)-β1b therapy, in particular in patients having preexisting thyroid autoimmune disorders (AITD), is well known. We report a case of a 60-year-old female, with a 15-year history of euthyroid autoimmune thyroiditis and a 3-year history of Multiple Sclerosis (MS), in care for the evaluation of hyperthyroidism. The patient started a specific immunomodulant IFN-β1a therapy (30 μg/week) twenty months before the first visit, during which complained tachycardia, weight loss, blurry vision with swollen eyes and excessive lacrimation. The thyroid hormone profile showed hyperthyroidism with positive TSH-receptor-autoantibodies. An orbit Magnetic Resonance Imaging (MRI) was performed, revealing bilaterally mild enlargement of the extraocular muscles and supporting the suspect of Graves ophthalmopathy (GO). To our knowledge, this is the first report of Graves disease (GD) and GO associated with IFN-β1a treatment in a patient with MS. This case report could open new interesting insights behind the immunopathogenesis of GD.
