Current Treatment Guidelines of SARS-CoV-2 Related Multisystem Inflammatory Syndrome in Children: A Literature Review and Expert Opinion

Abstract

Abstract Multisystem inflammatory syndrome in children (MIS-C) is a systemic disorder that seems to be associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since April 2020, there have been multiple reports about children with this new condition worldwide, including Europe, Asia, Latin America, and North America. The symptoms of this syndrome mimic the clinical manifestations of Kawasaki disease; therefore, the treatment of Kawasaki disease, as well as supportive care, was the management of choice in children with MIS-C in the early days of recognizing it. It is important to precisely ascertain the risk of COVID-19 infection and its severity in children and to acknowledge the management of this syndrome, with reliable data from cohorts, trials, and experts' opinions. In the current review, we summarize the current management guidelines for MIS-C and present our own protocol to answer some clinical questions regarding MIS-C management during the COVID-19 pandemic.
