    Abstract:
    INTRODUCTION: Antisynthetase syndrome (ASS) is characterised by a series of clinical manifestations such as myositis, fever, mechanic's hands and diffuse interstitial lung disease (ILD), all associated with positivity to antisynthetase antibodies. The presence of ILD will be that, to a great extent it will mark the response to treatment and prognosis. PATIENTS AND METHODS: Eleven cases of patients with ASS and pulmonary involvement in monitoring at a Pulmonary monographic consult in a third level hospital consult are described. RESULTS: Nine patients presented positivity to anti-Jo antibody and 2 to anti-PL12. Four patients' HRCT pattern showed NSIP, four UIP, one COP and 2 ground-glass opacity. A percentage of 73 were accompanied by bronchiectasis and bronchiolectasis and 27% honeycombing. Functional exploration was mainly affected by DLCO with up to 45% of the positive walking test. Corticodependence is highlighted, often requiring immunosuppressive treatment both chronically and in exacerbations. All patients maintain good prognosis so far. CONCLUSIONS: Patients with interstitial lung disease should have at least a determination of antisynthetase antibodies in order to identify this disease, better prognosis than other interstitial diseases such as idiopathic pulmonary fibrosis.
