Outcome Measures

Primary Outcomes (1)

  • Vitamin D level < 75 nmol/L

    6 months of supplementation

Secondary Outcomes (4)

  • Seizure rate

    6 months of supplementation

  • bone mineral density (BMD) measurement

    6 months of supplementation

  • Cost- effectiveness of vitamin D supplementation

    6 months of supplementation

  • Safety: Prevalence of hypercalcemia total calcium >2.7mg/dl, 25 OH vit D level> 250 nmol/l, and Urine calcium: creatinine ration > 1.2 mol/mol, or > 0.41g/g.

    6 months of supplementation

Eligibility Criteria

Age2 Years - 16 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Children aged between 2-16 years who were diagnosed with Epilepsy and being treated with AEDs
  • Followed up in the outpatient pediatric neurology clinic at King Khalid University Hospital during the period of two years.

You may not qualify if:

  • Children with pre-existing vitamin D metabolism problems; because they are known to need different vitamin D doses and monitoring for clinical improvement:
  • Vitamin D dependent rickets
  • Malabsorption syndromes like celiac disease, inflammatory bowel disease
  • Renal disease
  • Hepatic disease
  • Children who are not safe to start vitamin D supplementation; because vitamin D supplementation will causes toxicity and induces nephrocalcinosis:
  • Hypercalcemia at baseline total corrected calcium \>2.5mg/dl
  • Vitamin D level \> 250 nmol/L
  • Urine calcium: creatinine ration \> 1.2 mol/mol, or \> 0.41g/g.
