Lupus-Like Syndrome-A Rare Complication in Thionamide Treatment for Graves' Disease

Abstract

A patient with Graves' disease who experienced various allergic reactions to both PTU and MMI is reported. She developed fever, skin rash, lymphadenopathy, liver damage and moderate leukopenia during PTU administration. Furthermore, she developed an MMI-induced lupus-like syndrome characterized by generalized lympha denopathy, migrating polyarthritis and myalgia, and results of tests for anti-DNA antibody and anti-nuclear antibody, and LE were positive. All these abnormalities reverted to normal upon discontinuation of medication after subtotal thyroidectomy.
