Interstitial Lung Disease in Anti-Synthetase Syndrome
Abstract
Anti-synthetase syndrome is an autoimmune disorder characterized by the presence of autoantibodies against aminoacyl transfer RNA (tRNA) synthetases, and myositis, interstitial lung disease (ILD), arthritis, fever and Raynaud’s phenomenon (RP). We present a 54-year-old woman, who complained of fatigue, low-grade fever, myalgias, arthralgias, RP and dyspnoea on exertion. Chest CT scan revealed features of interstitial lung disease. Due to rapid deterioration of her lung function, she required oxygen support. The patient did not respond to empiric treatment with antibiotics. Autoantibody testing was remarkable for ANA positivity (1/160) and high-titre anti-Jo1 positivity. A diagnosis of anti-synthetase syndrome was made and the patient was placed on high-dose corticosteroids and rituximab with significant improvement. At 1-year follow up, she remains in good condition, without the need for oxygen supplementation. https://doi.org/10.31138/mjr.30.3.186
