Spontaneous Remission in a Patient with Anti-OJ Autoantibodies-positive Anti-synthetase Syndrome Following SARS-CoV-2 Infection and mRNA Vaccination

Abstract: Anti-synthetase syndrome (ASyS) is a subset of idiopathic inflammatory myopathies characterized by a triad of myositis, interstitial lung disease, and arthritis. Patients with ASyS are generally treated with glucocorticoids, immunosuppressants, or both. We encountered a 53-year-old woman who developed anti-OJ autoantibodies-positive anti-synthetase syndrome following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and CoV-2 messenger RNA (mRNA) vaccination. Her dyspnea and rash resolved within 4 weeks of the initial examination, achieving spontaneous remission without treatment 52 weeks after the diagnosis. This case suggests a potential association between SARS-CoV-2 infection, mRNA vaccination, and the transient development of anti-OJ antibodies-positive ASyS.
