Core Tip

Core Tip: Multisystem inflammatory syndrome in children (MIS-C) comprises a severe and out-of-control inflammatory response with multiorgan dysfunction following severe acute respiratory syndrome coronavirus 2 infection. Despite its severity, there are no definitive disease management guidelines for this condition. Conversely, the complex pathogenesis of MIS-C is still not completely understood, although it seems to rely upon immune dysregulation. Hence, in this study, we aim to bring together current evidence regarding the pathogenic mechanisms of MIS-C, clinical picture and management, in order to provide insights for clinical practice and implications for future research directions.
