Serological Biomarkers of Dermatomyositis – Associated Interstitial Lung Disease

Dermatomyositis (DM) is a subset of idiopathic inflammatory myopathies (IIM) which is characterized by chronic inflammation of skin and muscle weakness, and often involving other organs, such as skin, heart, gastrointestinal tract, pulmonary, and joints [1-5]. The subtypes of DM include classical DM, which has muscle manifestations as well as a variety of cutaneous manifestations; another subset of DM is called clinically amyopathic dermatomyositis (CADM), referring to the typical clinical manifestations of dermatomyositis skin and few have the clinical manifestations of muscle weakness [6,7].
