Déficit de vitamina D en niños ingresados en cuidados intensivos pediátricos
2016
Introduction Vitamin D is essential for bone health, as well as for cardiovascular and immune function. In critically ill adults vitamin D deficiency (VDD) is common, and is associated with sepsis and higher critical illness severity. Objectives To establish the prevalence of VDD and its association with clinically relevant outcomes in children admitted to a Paediatric Intensive Care Unit (PICU) in Concepcion, Chile. Patients and method Prospective observational cohort study in 90 consecutive children admitted to the PICU in a university general hospital. Blood was collected on admission to PICU and analysed for 25-OH-D levels. Severity of illness and vasopressor use were assessed using PRISM, PELOD, and vasoactive-inotropic score (VIS) score. VDD was defined as a serum 25-OH-D level 40 ml/kg in the first 24 h of admission (RR 1.5; 95%CI: 1.1-2.1, P <.05). Conclusions In this study, VDD at PICU admission was prevalent in critically ill children and was associated with adverse clinical outcomes. Further studies are needed to assess the potential benefit of optimizing vitamin D status in the PICU.
