Insights
Bisphosphonate therapy for pediatric osteoporosis is controversial due to limited long-term efficacy and safety data. Experts suggest use for severe fractures or vertebral collapse, not bone density alone.
Area of Science:
- Pediatric Endocrinology
- Bone Metabolism
- Pharmacological Therapies
Background:
- Childhood osteoporosis awareness is rising, increasing pressure to use adult bisphosphonate drugs.
- This review evaluates existing research on bisphosphonate therapy's efficacy and safety in pediatric osteoporosis.
Purpose of the Study:
- To examine the available research on bisphosphonate therapy for pediatric osteoporosis.
Main Methods:
- A review of medical literature, key articles, and consensus statements regarding bisphosphonate use in children up to June 2008.
- Comparison of studies with varying bisphosphonate agents, doses, and treatment durations.
Main Results:
- Bisphosphonate therapy for pediatric osteoporosis remains controversial.
- Inadequate long-term efficacy and safety data exist.
- Expert consensus suggests limiting use to children with recurrent fractures, symptomatic vertebral collapse, and low bone mass.
Conclusions:
- Current data do not support bisphosphonate use solely for reduced bone mass/density in children.
- Further research is essential to establish appropriate indications, optimal agents, dosages, and treatment durations for bisphosphonate therapy in pediatric patients.
Context:
As awareness of osteoporosis in childhood has increased, so have pressures to consider use of the pharmacological agents used to treat osteoporosis in adults. This review examines available research on the efficacy and safety of bisphosphonate therapy for pediatric osteoporosis.
Evidence Acquisition:
We reviewed the medical literature for key articles and consensus statements on the use of bisphosphonates in children through June 2008.
Evidence Synthesis:
We compared reports using varying bisphosphonate agents, doses, and duration of therapy to treat osteogenesis imperfecta and a variety of secondary causes of osteoporosis in children. Conclusions drawn from a recently published Cochrane analysis and the consensus statements from experts in the field were considered as well.
Conclusions:
Use of bisphosphonate therapy in pediatric patients remains controversial because of inadequate long-term efficacy and safety data. For this reason, many experts recommend limiting use of these agents to those children with recurrent extremity fractures, symptomatic vertebral collapse, and reduced bone mass. Current data are inadequate to support the use of bisphosphonates in children to treat reductions in bone mass/density alone. More research is needed to define appropriate indications for bisphosphonate therapy and the optimal agent, dose, and duration of use in pediatric patients.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
