Unexpected SARS-CoV-2 cardiorespiratory arrest in a myopathy patient undergoing immunosuppressive treatment: A case report.

RATIONALE: It is recommended that patients with Rheumatic diseases that are at high risk of developing active infections be screened for Tuberculosis, Hepatitis B, and Hepatitis C before receiving second-line immunosuppressive therapies. With the emergence 2019 novel coronavirus (SARS-CoV-2), expanded guidelines have not been proposed for screening in these patients before starting advanced therapy.

PATIENT CONCERNS: We present an unique circumstance whereas a patient with a 5 year history of inflammatory muscle disease, diagnosed by clinical history and muscle biopsy with elevated creatine kinase levels, suffered a hypoxemic cardiopulmonary arrest due to asymptomatic SARS-CoV-2 after receiving advanced immunosuppressive therapy.

DIAGNOSES: The patient presented with an acute exacerbation of inflammatory muscle disease with dysphagia, muscle weakness, and elevated creatine kinase.

INTERVENTIONS: After no improvement with intravenous immunoglobulin the patient received mycophenolate and plasma exchange therapy.

OUTCOMES: Subsequently the patient suffered a fatal hypoxemic cardiopulmonary arrest. Polymerase chain reaction test was positive for SARS-CoV-2 RNA.

LESSONS: We conclude that rheumatic patients, asymptomatic for SARS-CoV-2 infection, be screened and tested before initiating second-line immunosuppressive treatment.
