A severe anti MDA-5 antibodies associated amyopathic dermatomyositis

Lung damage during amyopathic dermatomyositis (ADM) associated with auto antibodies anti MDA-5 is serious. We report a rare observation of a severe ADM associated to anti MDA-5 antibodies complicated with diffuse interstitial lung disease (ILD) rapidly extensive and fatal.We report the observation of a Tunisian adult who was admitted for ADM. The anti MDA-5 antibodies were detected. He developed an ILD rapidly extensive to fibrosis. Corticosteroids were unefficient and he deceded of pneumomediastin and refractory respiratory distress.This observation illustrates the severity of ADM with anti MDA-5 antibodies. Every clinician should detect any ILD to avoid the progression to fibrosis.
