Antisynthetase syndrome and interstitial lung disease: A case report

Introduction: Myositis, Raynaud's phenomenon, fever, interstitial lung disease, mechanic's hands, and arthrop-athy are symptoms of Antisynthetase Syndrome (ASS), which is defined by the development of antibodies against t-ribonucleic acid (RNA) synthetase, particularly anti-Jo-1. Case presentation: The case is about 29 years female with 1 month history of non-productive cough and dyspnea on exertion which was later diagnosed as ASS. Discussion: The diagnosis of an inflammatory myopathy is based on clinical findings such as subacute develop-ment of symmetrical muscle weakness and signs such as laboratory investigations revealing skeletal muscle inflammation. Creatinine phosphokinase (CPK) is mainly used to demonstrate skeletal muscle involvement. Conclusion: Interstitial lung disease is a frequent occurrence and is associated with a bad prognosis during the course of antisynthetase syndrome.
