Vitamin D in Acute and Critically Sick Children with a Subgroup of Sepsis and Mortality: A Meta-Analysis

Abstract

A meta-analysis study was performed to evaluate the relationship between vitamin D deficiency children and sepsis and acute and critically mortality. Through a systematic literature search up to December 2019, 23 studies with 4451 children, 2500 children with vitamin D deficiency were identified reporting relationships between vitamin D deficiency and sepsis and/or acute and critical care unit mortality (six sepsis only, four acute and critically mortality only and 13 both sepsis and acute and critically mortality). Odd ratio (OR) with 95% confidence intervals (CIs) was calculated comparing vitamin D deficiency children to normal vitamin D children on the bases of sepsis and mortality in acute and critical care units using the dichotomous method with a random effect model. No significant difference was found between males and females in pooled studies all together (OR, 0.72; 95% CI, 0.43–1.22). Vitamin D deficiency children (OR, 2.24; 95% CI, 1.42–3.53) had higher sepsis compared to normal vitamin D children. Also, vitamin D deficiency children (OR, 1.77; 95% CI, 1.26–2.49) had higher acute and critically mortality compared to normal vitamin D children but not as much as that in sepsis. The extent of increased sepsis was higher than that in acute and critically mortality. The impact of vitamin D deficiency in children was observed in all populations. Based on this meta-analysis, vitamin D deficiency in children may have an independent-relationship with up to 2.24 fold risk of sepsis and acute and critical care unit mortality. This relationship forces us to recommend checking vitamin D concentration in all critically ill children.
