Vitamin-D Status and Clinical Outcomes in Critically Ill Children

Area of Science:

• Pediatric Critical Care Medicine
• Nutritional Biochemistry
• Clinical Outcomes Research

Background:

• Vitamin D deficiency is a global health concern, particularly prevalent in hospitalized populations.
• Assessing the impact of vitamin D status on critically ill pediatric patients is crucial for understanding disease progression and treatment efficacy.
• This study investigates the correlation between 25-hydroxy cholecalciferol levels and clinical outcomes in children admitted to a pediatric intensive care unit (PICU).

Observation:

• A cohort of 119 critically ill children (1 month to 14 years) admitted to the PICU was studied.
• Vitamin D levels were measured within 24 hours of admission, revealing a high prevalence of deficiency (47.05%).
• Mean serum 25-hydroxy cholecalciferol was 22.82 ± 16.48 nmol/L.

Findings:

• Despite the high prevalence of vitamin D deficiency, no statistically significant differences were observed in oxygen utilization, mechanical ventilation requirements, or length of PICU stay between deficient and sufficient groups.
• Antibiotic and steroid use also showed no significant variation between the groups.
• Overall mortality was 5.8%, with no significant difference in mortality rates between children with vitamin D deficiency and those with sufficient levels.

Implications:

• The findings suggest that while vitamin D deficiency is common in critically ill children, it may not be a primary determinant of short-term clinical outcomes or mortality in this population.
• Further research is warranted to explore potential long-term effects or specific subgroups that might benefit from vitamin D supplementation.
• These results contribute to the understanding of micronutrient status in pediatric critical care and inform clinical practice regarding vitamin D assessment and management.
