Insights
Pediatric intensive care unit (PICU) patients show a high prevalence of vitamin D deficiency upon admission. However, low vitamin D levels were not linked to increased mortality risk scores in these critically ill children.
Area of Science:
- Pediatric Critical Care Medicine
- Endocrinology
- Nutritional Science
Background:
- Vitamin D deficiency is a growing concern in various populations.
- Assessing vitamin D status in critically ill children is crucial for understanding potential health impacts.
Purpose of the Study:
- To determine the prevalence of 25-hydroxyvitamin D (25(OH)vitD) deficiency in pediatric intensive care unit (PICU) patients at admission.
- To investigate the association between 25(OH)vitD deficiency and predicted mortality risk scores in this cohort.
Main Methods:
- A prospective observational study enrolled 156 PICU patients and 25(OH)vitD levels were measured within 12 hours of admission.
- Vitamin D levels were compared to 289 healthy children, and deficiency was defined as < 20 ng/mL.
- Patients were stratified based on mortality risk scores (PRISM III/PIM 2) to compare 25(OH)vitD levels between high-risk and other groups.
Main Results:
- PICU patients had significantly lower median 25(OH)vitD levels (26.0 ng/mL) compared to healthy children (30.5 ng/mL) (p=0.007).
- The prevalence of vitamin D deficiency (< 20 ng/mL) was higher in PICU patients (29.5%) than in healthy children (15.6%) (p=0.01).
- No significant difference in 25(OH)vitD levels was observed between PICU patients with high mortality risk scores and those with lower scores (p=0.800).
Conclusions:
- Hypovitaminosis D (vitamin D deficiency) is common upon admission to the pediatric intensive care unit.
- Vitamin D deficiency in PICU patients was not associated with higher predicted mortality risk scores.
Objective:
to assess whether 25hydroxivitaminD or 25(OH)vitD deficiency has a high prevalence at pediatric intensive care unit (PICU) admission, and whether it is associated with increased prediction of mortality risk scores.
Method:
prospective observational study comparing 25(OH)vitD levels measured in 156 patients during the 12 hours after critical care admission with the 25(OH)vitD levels of 289 healthy children. 25(OH)vitD levels were also compared between PICU patients with pediatric risk of mortality III (PRISM III) or pediatric index of mortality 2 (PIM 2) > p75 [(group A; n = 33) vs. the others (group B; n = 123)]. Vitamin D deficiency was defined as < 20 ng/mL levels.
Results:
median (p25-p75) 25(OH)vitD level was 26.0 ng/mL (19.2-35.8) in PICU patients vs. 30.5 ng/mL (23.2-38.6) in healthy children (p = 0.007). The prevalence of 25(OH)vitD < 20 ng/mL was 29.5% (95% CI: 22.0-37.0) vs. 15.6% (95% CI: 12.2-20.0) (p = 0.01). Pediatric intensive care patients presented an odds ratio (OR) for hypovitaminosis D of 2.26 (CI 95%: 1.41-3.61). 25(OH)vitD levels were 25.4 ng/mL (CI 95%: 15.5-36.0) in group A vs. 26.6 ng/mL (CI 95%: 19.3-35.5) in group B (p = 0.800).
Conclusions:
hypovitaminosis D incidence was high in PICU patients. Hypovitaminosis D was not associated with higher prediction of risk mortality scores.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
