Abstract
An HIV-negative 9-year-old female was admitted to the pediatric ward at a tertiary hospital in Johannesburg, South Africa for investigation of a suspected rheumatic disorder complicated by proteinuria. She was subsequently diagnosed with pediatric systemic lupus erythematosus complicated by class IV lupus nephritis. Further into her admission, the patient developed hospital-acquired SARS-CoV-2 infection with mild clinical symptoms. Three weeks after her initial COVID-19 diagnosis, the patient developed multisystemic inflammatory syndrome. She was successfully treated with intravenous immunoglobulin therapy, intravenous corticosteroids, and thromboprophylaxis.
