  Purpose
Study will look at baseline Vitamin D levels, calcium, albumin, liver enzymes, testosterone, osteocalcin, urine N telopeptides, bone mineral density, nutritional assessment and physical activity assessment of boys with hemophilia A or B (ages 2-20 yrs). Patients with low vitamin D levels will receive therapeutic doses of Vitamin D. At end of one year follow up studies will be repeated.

Primary Outcome Measures:
  • Correlate between Vitamin D deficiency, low bone mass and lack of weight bearing physical activity [ Time Frame: 1year ]

Secondary Outcome Measures:
  • Determine bone mass (density) in hemophilia patients [ Time Frame: 1 yr ]
  • establish dose and duration of treatment with vitamin D [ Time Frame: 1 yr ]

Enrollment: 20
Study Start Date: March 2010
Study Completion Date: March 2015
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Hemophilia, Vitamin D deficiency
  1. Hemophilia, Rickets - Vitamin D per endocrine consult
  2. Hemophilia, Vitamin D deficient - Vitamin D 2000 units daily plus calcium
  3. Hemophilia, Normal Vitamin D - no intervention - observation only
Dietary Supplement: Vitamin D and calcium
Doses will be based on Vitamin D levels
