Anti-synthetase syndrome: a rare and challenging diagnosis for bilateral ground-glass opacities-a case report with literature review

Abstract

Background: Anti-synthetase syndrome (ASS) is an uncommon immune-mediated entity characterized by myositis, interstitial lung disease (ILD), non-erosive arthritis, and less common features such as fever, Raynaud's phenomenon, and skin changes in association with anti-aminoacyl-transfer-RNA antibodies, most commonly anti-Jo-1 antibodies.

Case presentation: We present a challenging and rare case of ASS-associated ILD presenting with unexplained respiratory symptoms and bilateral infiltrates on chest imaging during the COVID-19 pandemic. High clinical suspicion for ASS with early appropriate therapy with corticosteroids and immunosuppressive agents led to marked clinical improvement.

Conclusion: High index of suspicion for ASS is mandated in patients with unexplained ILD. A comprehensive autoimmune work-up is important as an early treatment with corticosteroids with or without immunomodulators improves patient outcomes and survival in an otherwise poor prognostic disease.

Keywords: Anti-synthetase syndrome; Autoimmune disease; Corticosteroids; Interstitial lung disease.
