ABSTRACT
The novel human coronavirus of 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has quickly swept throughout the entire world. As the ongoing pandemic has spread, recent studies have described children presenting with a multisystem inflammatory disorder sharing the features of Kawasaki disease (KD) and toxic shock syndrome, now named Multisystem Inflammatory Syndrome in Children (MIS-C). These cases report a similar phenotype of prolonged fever, multisystem involvement, and biomarkers demonstrating marked hyperinflammation that occurs temporally in association with local community spread of SARS-CoV-2. Herein, we describe the presentation, clinical characteristics, and management of an 11-year-old boy with prolonged fever, strikingly elevated inflammatory markers, and profound, early coronary artery aneurysm consistent with a hyperinflammatory, multisystem disease temporally associated with coronavirus disease 2019. We highlight our multidisciplinary team's management with intravenous immunoglobulin, methylprednisolone, and an interleukin-1 receptor antagonist, anakinra, as a strategy to manage this multisystem, hyperinflammatory disease process.
ABSTRACT
Multisystem inflammatory syndrome in children (MIS-C) has been observed in temporal association with coronavirus disease 2019 (COVID-19), typically within 2 to 6 weeks of illness or exposure. We present a case of MIS-C occurring 16 weeks after initial COVID-19 illness to highlight the prolonged period of risk for developing MIS-C.
