Adalimumab induced-inflammatory myopathy in rheumatoid arthritis

Abstract

The application of immunobiologics for the rheumatoid arthritis treatment may present as a rare complication the development of inflammatory myopathy. Until this moment, there have been described in literature only seven cases of inhibitors of tumor necrosis factor induced-myositis. In this paper, we report the case of the patient with 39 years-old with eight years of arthritis rheumatoid and that due to refractory to various immunosuppressive drugs, the adalimumab was introduced, and evolved to dermatomyositis status.
