简要总结
OBJECTIVES:
I. Determine the effects of alendronate sodium on skeletal remodeling and bone mineral density of the hip and spine in children with high-turnover idiopathic juvenile osteoporosis.
详细描述
PROTOCOL OUTLINE:
Patients receive oral alendronate sodium weekly for 1 year. Treatment continues in the absence of disease progression or unacceptable toxicity.

研究组 & 干预措施
1 Alendronate for 12 months
Ten children will take alendronate 35mg or 70mg weekly depending upon the body weight for 12 months. Patients will also take calcium supplement daily.
干预措施: Alendronate (Drug)
结局指标
主要结局
Number of Participants With Increased Bone Mineral Density
时间窗: at 12 months
Number of participants with increase in bone mineral density at Lumbar Spine and/or Hip at 12 months as compared to the bone mineral density at Lumbar Spine and/or Hip obtained before therapy (baseline values)
次要结局
- Participants (1) With Fractures Before and After Therapy,(2)Analysed for Average Changes From High to Near Normal Mineral Apposition Rate (MAR) After Therapy,(3)Analysed for Average Insignificant Changes in Biochemical Markers After Therapy.(Before and 12 months after treatment with alendronate)
