MIS-C: Diagnosis, Management, and Outcomes

Year: 2025

Type: article

Abstract: Multisystem inflammatory syndrome in children (MIS-C) is an emergent postinfectious hyperinflammatory disorder predominantly affecting the pediatric population following COVID-19 infection. Clinically, it is characterized by persistent fever, shock, multiorgan involvement, and potentially severe cardiovascular involvement. This comprehensive review synthesizes current evidence on the epidemiology, pathophysiology, clinical presentation, diagnostic criteria, with particular emphasis on the management of MIS-C. We also stress on the importance of distinguishing MIS-C from phenotypically similar entities. Acute-phase management centers on supportive care, hemodynamic stabilization, and targeted immunomodulation, with intravenous immunoglobulin, corticosteroids, and biologic forming the therapeutic cornerstone. Thromboprophylaxis is frequently warranted due to the elevated thromboembolic risk, and long-term follow-up is essential to monitor for cardiac, gastrointestinal, and neurologic complications. Additional considerations include postrecovery vaccination protocols and the use of extracorporeal membrane oxygenation in cases of refractory cardiorespiratory failure. Despite advancements in clinical outcomes, diagnostic ambiguity and heterogeneous management guidelines continue to pose significant challenges.
