Carbimazole induced ANCA Positive Vasculitis

摘要

Anti-throid drugs like propylthiouracil and carbimazole are the main drugs prescribed for hyperthyroidism worldwide. Vasculitis related to anti-thyroid medication is very rare and can be potentially life threatening, if not recognized early. We report a female patient with Graves’ Disease who developed ANCA positive vasculitis due to carbimazole. The episode was characterized by a Raynaud’s Phenomenon of hands and feet and small joint arthritis. To our knowledge this is the first ANCA positive carbimazole induced vasculitis case reported from United Arab Emirates.
