Clinical manifestations of dermatomyositis and clinically amyopathic dermatomyositis patients with positive expression of anti–melanoma differentiation–associated gene 5 antibody

Abstract

Anti-MDA-5 antibody levels closely correlate with the severity of skin ulcerations, ILD, and the prognosis of the disease. Dynamic observation of serum anti-MDA-5 antibody levels would be helpful in predicting the course of ILD and facilitating better therapeutic targeting.
