Multisystem Inflammatory Syndrome in Children (MIS-C) Associated With COVID-19 Infection in Morocco

Introduction. This study aims to describe the clinical and paraclinical characteristics of Multisysteminflammatory syndrome in children (MIS-C). Methods. A retrospective study encompassing 52 children diagnosed with MIS-C according to the World Health Organization criteria, over a 3-year period at Abderrahim Harrouchi Hospital in Morocco. Results. The median age was 6 years (IQR: 1-14), with a sex ratio of 1.16 (28 boys and 24 girls). Clinical manifestations were predominantly characterized by fever in all cases (100%), respiratory and gastrointestinal symptoms in 30 cases (58%) and 23 cases (44%) respectively, and shock in 9 cases (17%). We noted a myocarditis in 6 cases (12%). The treatment comprised intravenous human Immunoglobulin combined with methylprednisolone in all patients (100%). Conclusion. The characteristics of our MIS-C patients were similar to those in the literature, but more studies are needed to confirm these results.
