Biochemical abnormalities among patients from 0 to 3 years old with COVID-19 as a sign of subclinical forms of multisystem inflammatory syndrome in children

Abstract

While studying COVID-19 cases among children, one of the most important areas is the study of the multisystem inflammatory syndrome in children. This study aims to analyze the biochemical parameters of blood serum in children from 0 to 3 years old, that is, belonging to the age group atypical for the development of a clinically manifest multisystem inflammatory syndrome. It has been revealed that more than a half of the subjects have abnormalities in the biochemical parameters of blood serum corresponding to laboratory markers of the multisystem inflammatory syndrome in children, which indicates the possibility of the development of subclinical forms of this syndrome, associated in time with COVID-19, in children of different age groups. The results of the study substantiate the need for further investigation of biochemical parameters in children of different ages and for finding a solution to the issue of dynamic monitoring of children with identified abnormalities, taking into account the possibility of long-term impact of SARSCoV-2 on the organs and systems of a child's body.
