Abstract

A 50-year-old woman with a history of Crohn’s disease treated with adalimumab presented with left hand pain and duskiness. Angiogram showed non-filling of the radial and digital arteries of the hand. Antiphospholipid antibody testing was positive, leading to a diagnosis of antitumour necrosis factor-induced antiphospholipid syndrome. Adalimumab was discontinued, and she was treated with the vitamin K antagonist warfarin and low-dose aspirin. Upon resolution of the antiphospholipid antibodies, she was transitioned to aspirin alone without recurrence of thrombosis.
