Polymyositis (PM) and dermatomyositis (DM) are classified as idiopathic inflammatory myopathies (IIMs) that are systemic inflammatory diseases (connective tissue diseases) of unknown cause characterized by skeletal muscle inflammation and the involvement of other organs such as skin, lung, heart and joints.
Within this white paper, Professor Tsuneyo Mimori of Kyoto University describes the background to the development of anti-ARS testing and the clinical significance of these antibodies.
These intriguing new findings give hope to the possibility that this antibody may someday become a new tool for diagnosing PM/DM!
