Current Prognostic Models Fail to Reliably Distinguish Kawasaki Disease From Pediatric Multisystem Inflammatory Syndrome Temporally Associated With COVID-9

Background: Along with the emergence of coronavirus disease 2019 (COVID-19), a hyperinflammatory multisystemic syndrome in children called PIMS appeared. Despite its close similarity to the Kawasaki disease (KD), the conclusion of PIMS being a distinct disease entity was reached quickly. Since then, research projects have been implemented to find differences and reliable distinction parameters with conflicting results. Therefore, the aim of this study was to explore existing prognostic models on
