Immune-mediated necrotizing
myopathy (IMNM) is a rare form of idiopathic immune
myopathy (IIM) that requires
immunotherapies, including immunosuppressive medications, if severe. There is a paucity of data regarding outcomes of patients with immune-mediated
polymyositis who continue immunosuppressive medications during the
COVID-19 pandemic. This is the first reported case of
COVID-19 in a patient with IMNM. Despite being on two
immunotherapies, having risk factors, and having radiographic abnormalities on chest X-ray, the patient had an unremarkable
COVID-19 course. He was discharged from the emergency department with a 7-day course of
azithromycin and quickly resumed his
immunotherapies, but he experienced a flare in his
myositis. The 14-week follow-up computed tomography (CT) was negative for residual
pneumonitis or
fibrosis. More data are needed regarding management and prognosis of patients with
connective tissue diseases who become infected with SARS-CoV-2.
