Abstract:

Myositis antibodies are divided into myositis-specific autoantibodies (MSA) and myositis-associated autoantibodies (MAA). There are heterogeneity in the mechanism, clinical features and prognosis of interstitial lung disease (ILD) in the different myositis antibodies. In MSA, anti-melanoma differentiation-related gene 5 (MDA5) antibody and anti-aminoacyl synthetase (ARS) antibody are highly correlated with the occurrence of ILD. Patients with MDA5+DM-ILD usually have a rapidly progressive and poor prognosis. The progress of ILD in ARS+ DM patients was slow, and the response to treatment is good, but it is easy to relapse. In MAA, anti-Ro52 antibodies often coexist with MSA antibodies, and clinical manifestation is closely related to coexisting antibodies. This review has summarized roles of myositis antibodies in ILD.

Key words: dermatomyositis, interstitial lung disease, antoantibody, clinical features, prognosis
