Insights
Pamidronate therapy improved daily activities, reduced pain, and increased bone density in children with osteogenesis imperfecta (OI). This bisphosphonate treatment positively impacted overall well-being and functional status in young patients.
Area of Science:
- Pediatric Endocrinology
- Bone Metabolism
- Genetic Disorders
Background:
- Osteogenesis imperfecta (OI) is a rare genetic disorder characterized by fragile bones and skeletal deformities.
- Current treatments aim to improve bone strength and reduce fracture risk, but effects on daily function and well-being require further evaluation.
Purpose of the Study:
- To assess the impact of intravenous pamidronate therapy on functional abilities, pain levels, well-being, and bone mineral density in children diagnosed with osteogenesis imperfecta.
- To determine if pamidronate treatment influences the health status of pediatric OI patients.
Main Methods:
- A prospective observational study involving 43 children with OI (age range: 4 months to 16 years).
- Monthly intravenous pamidronate infusions administered over one year.
- Outcome measures included the Pediatric Evaluation of Disability Inventory (PEDI), a well-being score, pain frequency, and bone density via DXA scans, with data collected pre- and post-treatment.
Main Results:
- Significant improvements were observed in self-care and mobility scores on the PEDI (Functional Skill and Caregiver Assistance scales).
- Children experienced a reduction in skeletal pain and reported increased well-being.
- Bone mineral density (BMD) showed an increase following one year of pamidronate treatment, with younger children demonstrating greater PEDI improvements.
Conclusions:
- Intravenous pamidronate therapy demonstrated significant benefits for children with osteogenesis imperfecta.
- The treatment positively influenced functional status, skeletal pain, well-being, and bone density, aligning with the International Classification of Functioning, Disability and Health (ICF).
- Bisphosphonate therapy represents a valuable therapeutic option for managing OI in pediatric populations.
Aim:
To evaluate the effect of intravenous pamidronate therapy on everyday activities, well-being, skeletal pain and bone density in children with osteogenesis imperfecta (OI).
Methods:
In a prospective observational study, monthly intravenous pamidronate infusions were given to 43 children (aged 4 months-16 years) with different severity and form of OI. Outcome measures included the Pediatric Evaluation of Disability Inventory (PEDI), a score of well-being, registration of days with pain and bone density measured by using dual energy X-ray absorptiometry (DXA). Data were collected before and after the first year of treatment.
Results:
Self-care and mobility measured by PEDI increased significantly in both the Functional Skill scale and in the Caregiver Assistance scale. The youngest children improved more than the older ones according to the PEDI. The days with skeletal pain were reduced and both well-being and bone density increased.
Conclusions:
Intravenous treatment with bisphosphonates influenced health status, according to the International Classification of Functioning, Disability and Health (ICF). This group of 43 children experienced beneficial effects on everyday activities, skeletal pain, well-being and bone density.

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...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

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...
