Context Vitamin D is needed for the proper function of different organs of the body. A few studies have assessed vitamin D status in critically ill children and reported the prevalence of vitamin D deficiency (VDD) in the range of 30–71%. Aim The objectives of this study were to assess the prevalence of VDD in a pediatric ICU (PICU) patients and to determine whether there is any relationship between VDD and illness severity, mortality, or length of PICU stay. Design and settings We carried out a cross-sectional study of serum 25(OH)-vitamin D levels, measured during the first day of admission to a 10-bedded medical PICU at the Children’s Cairo University. Materials and methods We analyzed demographic data, pediatric risk of mortality III, and pediatric logistic organ dysfunction between normal and VDD groups in the PICU. Results The prevalence of VDD was 44% and that of severe VDD was 34% in critically ill Egyptian children at the onset of critical illness. The median level of vitamin D in the whole group was 59 nmol/l and in deficient group it was 17 nmol/l. Infants had higher median vitamin D levels than those above 1 year of age, but with no statistical difference. VDD patients had higher pediatric logistic organ dysfunction (12 vs. 10; P=0.001) and lower platelet counts (240 vs. 331; P=0.021). Pediatric risk of mortality III, inotropes, sepsis, ventilation, duration of PICU stay, and mortality were not related to VDD. Conclusion VDD is highly prevalent in critically ill children and is observed to be associated with organ dysfunction on admission.
