Multisystem Inflammatory Syndrome in Children: sectional study of cases and factors associated with deaths during COVID-19 pandemic in Brazil, 2020

Abstract

Objective: To describe the clinical-epidemiological profile of Multisystem Inflammatory Syndrome in Children (MIS-C) cases and to identify factors associated with MIS-C deaths in Brazil, 2020. Methods: Cross-sectional study, based on MIS-C national monitoring database in Brazil, 2020. Simple and multiple logistic regression was performed to estimate crude and adjusted odds ratios (OR). Results: The median age of cases (n=652) was 5 years, 57.1% were male, 52.0% were brown race/color and 6.4% died. The odds of death was greater among those who presented O₂ saturation <95% (ORa=4.35 – 95%CI 1.69;11.20) and altered result of urea (ORa=5.18 – 95%CI 1.91;14.04); lower in the absence of cutaneous lesion such as rash (ORa=0.23 – 95%CI 0.09;0.62), with the use of anticoagulants (ORa=0.32 – 95%CI 0.12;0.89) and of immunoglobulins (ORa=0.38 – 95%CI 0.15;1.01). Conclusion: Fatality rates was higher among cases that presented O₂ saturation<95% and altered urea, and lower among those with cutaneous lesion, who used immunoglobulins and anticoagulants.
