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.

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...
