Três casos de miosite induzida pelo anti‐TNF e revisão da literatura

Abstract

Anti‐tumor necrosis factor (anti‐TNF) drugs are frequently preferred in the treatment of rheumatologic diseases and other inflammatory diseases. The development of myositis after using anti‐TNF is a rare clinical condition. Here we aimed to report cases who developed myositis after using anti‐TNF and review the current literature. We report two cases of rheumatoid arthritis (RA) and a case of ankylosing spondylitis (AS) developed idiopathic inflammatory myopathy following anti‐TNF therapy. In conclusion, myositis could develop during anti‐TNF therapy, so these patients should be evaluated carefully initially for myositis and should be closely monitored due to the potential for developing myositis in treatment process.
