Patients will receive low-dose vitamin D (200 IU/d)
Patients will receive high-dose vitamin D (1600 IU/d)
Outcomes
Primary Outcome Measures
Calcium level and activity
Serum calcium level will be measured and analyzed using Advia 1800 chemistry system (Simens Germany). Normal level: 8.5 to 10.5 mg/dl
Phosphorus level and activity
Serum phosphorus level will be measured and analyzed using Advia 1800 chemistry system (Simens Germany). Normal level: 3.4 to 4.5 mg/dl
Alkaline phosphatase level and activity
Serum alkaline phosphate level will be measured and analyzed using Advia 1800 chemistry system (Simens Germany). Normal level: 50-100 U/L.
25-Hydroxy Vitamin D
Serum 25-Hydroxy Vitamin D level will be measured and analyzed using Electrochemilumiescence binding assay on cobas e immunoassay analyzer. The reference range of the total 25(OH)D level is 25-80 ng/mL.
Bone fracture
This will be evaluated using an x-ray of left wrist
Intracortical resorption
This will be evaluated using an x-ray of left wrist
Losing the sharp bone border (fraying)
This will be evaluated using an x-ray of left wrist
Cupping of metaphyseal edge of bone
This will be evaluated using an x-ray of left wrist
Widening of the distal end of the metaphysis of bone
This will be evaluated using an x-ray of left wrist
