Abstract:

Dermatomyositis (DM) is an idiopathic inflammatory myopathy (IIM). DM patients are usually accompanied by extramuscular manifestations such as arthritis, cardiomyopathy, interstitial lung disease (ILD), and malignant tumors. ILD and associated malignant tumors are the main causes of death in DM patients. Because the clinical characteristics, treatment response, and prognosis of DM patients are very different, it is very important to predict the prognosis of DM patients before treatment. Myositis specific autoantibodies (MSAs) and myositis associated autoantibodies (MAAs) can not only be used for diagnosis, but they are also useful for predicting the clinical characteristics, response to treatment, and prognosis of DM patients, which is helpful to better manage DM patients in routine clinical practice. This review describes how to incorporate autoantibody results into clinical practice in patients with DM, mainly adult patients.

Key words: Autoantibodies, Biomarkers, Dermatomyositis, Interstitial lung disease, Malignant tumors
