The Heart of the Problem in Multisystem Inflammatory Syndrome in Children

Brittany P Boribong et al. Med. .

Abstract

Multisystem inflammatory syndrome in children (MIS-C) is a severe, life-threatening, post-COVID-19 hyperinflammatory illness that is not yet fully understood. In this issue of Med, de Cevins et al. used a multi-parametric approach to define COVID-19-related disease, specifically identifying a molecular signature of the most severe form of COVID-19-related illness: MIS-C with myocarditis.1.

Distinct molecular signature within MIS-C with severe myocarditis A multi-parametric approach was utilized to study pediatric patients with acute infections and post-acute hyperinflammation related to SARS-CoV-2. Cytokines expression, cellular profiling and single cell gene expression was used. Pediatric patients with MIS-C with myocarditis showed a distinct molecular signature, including increased NF-κB signaling, leading to increased TNF-α, and low type-I and type-II interferon response. This molecular signature is distinct from acute COVID-19 and MIS-C without myocarditis.
