Pulmonary function tests, interstitial lung disease, and lung function decline in outpatients with classic and clinically amyopathic dermatomyositis

Interstitial lung disease (ILD) is common among patients with both classic dermatomyositis (DM) and clinically amyopathic dermatomyositis (CADM), patients with classic skin manifestations without weakness. ILD prognosis is thought to be worse in patients with CADM, but this observation may be due primarily to an increased frequency of rapidly-progressive ILD. This article is protected by copyright.
