Objective - To assess 25(OH)D status in children with Multisystem Inflammatory Syndrome (MIS-C) associated with SARSCoV- 2 infection, and the association between serum levels of 25(OH)D and inflammatory marker values. Patients and methods - This retrospective study was conducted at the Clinic for Children's Diseases, University Clinical Center, Tuzla in the period from November 2020 to November 2021. Results - The study included 23 children with MIS-C with a median age of 6.9 years, and 22 children with acute SARS-CoV-2 infection, with a median age of 1.1 years. Both groups of children had low serum levels of 25(OH)D in the range of deficiency; median levels of 25(OH)D in MIS-C children were lower (median 44.60 nmol/L) than in children with acute SARS-CoV-2 infection - median 52.45 nmol/L. There was no statistically significant difference in 25(OH) D levels between the two groups of children included in the study (P=0.33). The same number of children in both groups had adequate serum levels of 25(OH)D. The children in both groups had elevated markers of inflammation, but we did not find a significant correlation between the values of 25(OH)D and the inflammatory marker values. Conclusion - Deficiency of 25(OH) D could be one of the precipitating factors that lead to the development of both MIS-C - related SARS-CoV-2 and more severe forms of acute infection. 25(OH)D enriched food, as well as supplementation with 25(OH)D, should be considered a long-term strategy in all high-risk children and adolescents.
