Cardiac involvement in multisystem inflammatory syndrome associated with COVID-19 in children: Correlation with biological markers

Abstract

Multisystem inflammatory syndrome in children (MIS-C) is a new disease described as early as April 2020 following the COVID-19 pandemic. We conducted a retrospective mono-centric study from May 2020 to December 2022. We identified 24 patients with MIS-C with an average age of 5.6 years. Gastrointestinal symptoms were present in 79.2% of patients, while mucocutaneous signs were present in 87.5%. All patients had a marked biological inflammatory syndrome. The analytical study did not show a correlation between levels of biomarkers of inflammation and ultrasound data.
