High-dose vitamin D supplementation in children with cerebral palsy or neuromuscular disorder

Area of Science:

• Pediatric Endocrinology
• Nutritional Science
• Bone Metabolism

Background:

• Adequate vitamin D is vital for skeletal health, especially in children with neuromuscular disorders like cerebral palsy, who face higher osteoporosis risks.
• Children with disabilities often exhibit inadequate vitamin D levels, necessitating targeted interventions.

Purpose of the Study:

• To assess the impact of high-dose vitamin D3 supplementation on vitamin D status in disabled children.
• To evaluate the safety and efficacy of a specific vitamin D supplementation protocol in this vulnerable population.

Main Methods:

• A 10-week study involving 44 disabled children, with 21 receiving 1000 IU vitamin D3 orally five days a week, and 23 serving as a control group.
• Serum 25-hydroxyvitamin D levels were measured at baseline and post-intervention to track changes.
• Other relevant parameters were monitored to assess safety and potential side effects.

Main Results:

• The supplemented group showed a significant increase in median serum 25-hydroxyvitamin D levels (from 44 to 56 nmol/L).
• The control group experienced a significant decrease in median vitamin D levels (from 44 to 37 nmol/L).
• No significant adverse effects, including hypercalcemia, were observed in the supplemented group.

Conclusions:

• Hypovitaminosis D (vitamin D deficiency) is common among disabled children.
• Supplementation with 1000 IU vitamin D3, administered five days a week, effectively improves vitamin D status in disabled children.
• This supplementation regimen is safe and well-tolerated, with no observed adverse effects.
