[Acute respiratory distress revealing antisynthetase syndrome].

Antisynthetase syndrome is a clinical entity characterized by specific anti-aminoacyl-tRNA-synthetase antibodies usually associated with inflammatory myopathy and interstitial lung disease. The classic presentation of the pathology is the pulmonary interstitium involvment, wich commonly determines the global prognosis. The subsequent diagnosis of antisynthetase syndrome in patients with acute respiratory distress syndrome (ARDS) is unusual, even more so when a veino-veinous (VV) extracorporeal membrane oxygenation (ECMO) is required. This article presents a clinical case of antisynthetase syndrome with severe ARDS successfully treated with immunosuppressive agents and ECMO.
