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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determine bone mass (density) in hemophilia patients [ Time Frame: 1 yr ] [ Designated as safety issue: No ]
  • establish dose and duration of treatment with vitamin D [ Time Frame: 1 yr ] [ Designated as safety issue: No ]

Estimated Enrollment: 40
Study Start Date: March 2010
Estimated Study Completion Date: March 2014
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
