Immunological basis that supports the treatment of Multi-System Inflammatory Syndrome in Children (MIS-C/PIMS)

Pediatric inflammatory multisystemic syndrome temporarily associated with COVID-19 (MIS-C/PIMS) is a new post-infectious condition, secondary to SARS-CoV2 infection. It has been characterized by an inflammatory response with multisystem involvement, involving several mechanisms of immune damage such as an exaggerated increase in cytokines and epithelial damage. Immunomodulatory treatment is aimed at controlling the manifestations of hyperinflammation, to stabilize and prevent long-term sequelae. © 2023 Instituto Nacional de Pediatria. All rights reserved.
