title: A case report of tumor necrosis factor-alpha antibody-induced thrombocytopenia associated with emerging IgM anticardiolipin antibody in patients with scleroderma overlap/rheumatoid arthritis.
abstract: It is commonly believed that infliximab-induced anticardiolipin antibody belongs to the IgM subclass but not the IgG subclass and that the IgM subclass could not produce clinical symptoms. However, we had a patient with scleroderma overlap/rheumatoid arthritis who developed thrombocytopenia associated with the appearance of IgM anticardiolipin antibody after treatment with infliximab. This is a report of a rare case that should make us aware of the possibility of the development of thrombocytopenia with the appearance of IgM anticardiolipin antibody induced by infliximab.
