Insights
Pamidronate and clodronate, types of bisphosphonates, effectively treated hypercalcemia in a child with osteogenesis imperfecta. These medications may also reduce bone turnover in this condition.
Area of Science:
- Pediatric Endocrinology
- Metabolic Bone Disease
- Pharmacology
Background:
- Osteogenesis imperfecta (OI) is a genetic disorder characterized by brittle bones.
- Hypercalcemia, particularly after immobilization, is a serious complication in OI patients.
- Bisphosphonates are a class of drugs known to inhibit bone resorption.
Observation:
- A child with osteogenesis imperfecta experienced recurrent symptomatic hypercalcemia following immobilization after fractures.
- The patient's response to intravenous pamidronate was observed.
- The efficacy of oral clodronate in preventing subsequent episodes was evaluated.
Findings:
- Pamidronate demonstrated a response in managing hypercalcemia in this pediatric OI case.
- Oral clodronate proved effective in preventing immobilization-induced hypercalcemia in the same child.
- These findings suggest bisphosphonates' potential role in managing OI complications.
Implications:
- Bisphosphonates may be a valuable therapeutic option for managing hypercalcemia in osteogenesis imperfecta.
- Further research into bisphosphonates could elucidate their broader role in decreasing bone turnover in OI.
- This case highlights the potential utility of bisphosphonates in improving outcomes for children with OI.
Abstract:
The response to the bisphosphonate, pamidronate, is reported in a child with osteogenesis imperfecta who had recurrent symptomatic hypercalcaemia after immobilisation following fractures. Oral clodronate was effective in the prevention of immobilisation hypercalcaemia in the same child. The bisphosphonates may have other roles in osteogenesis imperfecta by decreasing bone turnover.

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...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
