Brief Summary

Vitamin D plays an important role in calcium balance, heart and lung health, inflammation, infection prevention, and muscle strength. Due to these roles, it has been suggested that critically ill patients with low vitamin D levels might have higher rates of death and worse long-term health. We believe that identifying critically ill children with vitamin D deficiency and then restoring vitamin D levels quickly could represent a safe, easy and inexpensive means of reducing patient illness, preventing death and improving quality of life. This clinical trial will determine whether rapid normalization of vitamin D deficiency improves survival and health-related quality of life following critical illness. The VITdALIZE-KIDS trial is a multicentre randomized clinical trial in Canadian Pediatric Intensive Care Units (PICUs). Critically ill children who agree to participate (consent given by caregivers) will have their blood vitamin D level measured, and those who are vitamin D deficient will be randomized to receive a single dose of either high-dose vitamin D3 or placebo (no drug). Study participants assigned to the high-dose vitamin D arm will receive 10,000 IU/kg of enteral cholecalciferol (up to a maximum of 400,000 IU). We have tested this dose in a pilot trial, and no patient experienced serious adverse events related to vitamin D administration. Patients will be followed for 90 days to determine whether they survived and had a significant change in their health and quality of life. Vitamin D deficiency is a common problem not only among critically ill Canadian children, but in PICUs worldwide. In addition to being applicable in Canada, our study protocol was designed to be generalizable and meaningful to critically ill children worldwide.

Outcome Measures

Primary Outcomes (1)

  • Health related quality of life

    The primary outcome will be health related quality of life. Health related quality of life will be measures using the age-appropriate PedsQL scale (Ages: 2-7, PedsQL 4.0 Generic Core Scales; Ages 1-24 months: PedsQLâ„¢ Infant Core Scales (1-24 months). The PedsQL requires only 23 items to score (36 items for the infant scales), a task easily completed in 5-7 minutes and assesses four domains: physical, emotional, social, and school functioning. The mean PedsQL Core Scale is equal to the sum of all items over the number of items answered on all the Scales and generates a number out of 100. The scoring for the scale is the same for both the PedsQL 4.0 Generic Core Scale and PedsQL Infant Core Scale, allowing the score from either scale to be reported together as one outcome.

Study Arms (2)

Vitamin D

EXPERIMENTAL

Approximately half of the subjects randomized into VITdALIZE-KIDS will be randomized into the Vitamin D Group and will receive a single dose of cholecalciferol at enrolment. Participants may also receive standard vitamin D dosing at the discretion of the care team (e.g. 400-1000 IU/day).

Drug: Cholecalciferol

Placebo

PLACEBO COMPARATOR

Approximately half of the subjects randomized into VITdALIZE-KIDS will be randomized into the Placebo Group and will receive a single dose of placebo at enrolment. Participants may also receive standard vitamin D dosing at the discretion of the care team (e.g. 400-1000 IU/day).

Other: Placebo

Interventions

Single enteral cholecalciferol load at a dose of 10,000 IU/kg (maximum 400,000 IU)

Vitamin D
PlaceboOTHER

Single enteral placebo dose equivalent in volume to the appropriate weight-based dose of cholecalciferol

Placebo
