Insights
Pediatric rheumatic disorders pose significant risks to children's bone health, potentially causing fractures and hindering peak bone mass development. This review examines these risks and assessment methods for pediatric bone health.
Area of Science:
- Pediatric Rheumatology
- Bone Metabolism
- Skeletal Health
Background:
- Children with rheumatic disorders face numerous bone health risks, including inflammation and medication side effects.
- These risks can lead to immediate fractures or long-term deficits in bone mass accrual.
Purpose of the Study:
- To review bone health challenges in pediatric rheumatic disorders.
- To outline skeletal growth expectations and assess bone fragility technologies in children.
- To discuss inflammation's role in bone resorption and future research needs.
Main Methods:
- Literature review of pediatric rheumatic disorders and bone health.
- Analysis of risk factors, including inflammation and glucocorticoid therapy.
- Evaluation of skeletal assessment technologies for pediatric populations.
Main Results:
- Rheumatic diseases present immediate and delayed threats to bone health in children.
- Inflammation significantly contributes to bone resorption.
- Current literature highlights bone deficits and risk factors, with limitations.
Conclusions:
- Pediatric rheumatic disorders critically impact bone health, necessitating careful monitoring.
- Understanding molecular mechanisms of inflammation is key to mitigating bone loss.
- Further research is needed to optimize bone health management in these children.
Abstract:
Children with rheumatic disorders have multiple risk factors for impaired bone health, including delayed growth and development, malnutrition, decreased weight-bearing activity, inflammation, and glucocorticoid therapy. The impact of rheumatic disease during childhood may be immediate, resulting in fragility fractures, or delayed, because of suboptimal peak bone mass accrual. Recent years have seen increased interest in the effects of pediatric rheumatic disorders on bone mineralization, such as juvenile rheumatoid arthritis, systemic lupus erythematosus, and juvenile dermatomyositis. This review outlines the expected gains in bone size and mass during childhood and adolescence, and summarizes the advantages and disadvantages of available technologies for the assessment of skeletal growth and fragility in children. The varied threats to bone health in pediatric rheumatic disorders are reviewed, with emphasis on recent insights into the molecular mechanisms of inflammation-induced bone resorption. The literature assessing bone deficits and risk factors for impaired bone health in pediatric rheumatic disorders is reviewed, with consideration of the strengths and limitations of prior studies. Finally, future research directions are proposed.

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...
