In PL-12 patients inicial and respiratory syntoms were predominant, whereas in the Jo-1 patients were more frequent extrapulmonary manifestations and acute presentation. Whatever type of AS, 84.6% showed interstitial disease in HRCT, indistinguishable from other ILD patterns. Response to treatment with corticosteroids and / or immunosuppressive was good (defined by a smaller drop of 10% in FVC in one year) at 84.6%.Conclusions: The AS is common in patients with ILD and may occur without extrapulmonary manifestations, indistinguishable from idiopathic forms of ILD. The antisynthetase antibodies usually present with pulmonary involvement. Therefore we suggest a screening of antisythetase antibodies should be done in patients with ILD.
