摘要
Purpose of review To review recent advances in our understanding of autoantibodies associated with dermatomyositis and the autoimmune necrotizing myopathies. Recent findings Autoantibodies preferentially associated with dermatomyositis include those recognizing Mi-2, MDA5, TIF1 gamma, and NXP-2. Each of these is associated with a distinct clinical phenotype. Autoantibodies found in patients with autoimmune necrotizing myopathies recognize signal recognition particle and 3-hydroxy-3-methylglutaryl-coenzime A reductase (HMG-CoA) reductase. The latter are found in patients with statin-associated autoimmune muscle disease. Summary As these are helpful both diagnostically and prognostically, a rheumatologist should be familiar with autoantibodies found in patients with dermatomyositis and the autoimmune necrotizing myopathies.
