ABSTRACT
Key Clinical Message In a patient with anti-aminoacyl tRNA synthetase antibody and anti-OJ antibody syndrome, interventions likes warming, prostaglandins, and antiplatelets failed. However, prednisolone pulse treatment rapidly halted disease progression. Patients with mild interstitial pneumonia, myositis, and extremity necrosis should be promptly considered for anti-synthetase syndrome and receive immunosuppression after ruling out other causes. Abstract Anti-aminoacyl tRNA synthetase (ARS) autoantibodies are myositis-specific, and patients who test positive for ARS and have common clinical features are usually diagnosed with antisynthetase antibody syndrome (antisynthetase syndrome). Anti-ARS antibodies include histidyl-tRNA synthetase-1 (Jo-1), anti-threonyl (PL-7), anti-alanyl (PL-12), anti-glycyl (EJ), anti-asparaginyl (KS), anti-tyrosyl (Ha), and anti-phenylalanyl (Zo) tRNA synthetases. Among these, anti-isoleucyl tRNA synthetase (OJ) autoantibodies are extremely rare, and patients with these are frequently complicated by interstitial pneumonia. We report the case of an older man with ARS antibody syndrome who tested positive for anti-OJ and anti-Sjögren's-syndrome-related antigen A (Ro-52) antibodies. He had muscle weakness due to myositis and unparalleled rapid and severe finger necrosis. Pulsed prednisolone effectively treated the myositis symptoms and terminated the progression of finger necrosis.
