Mary Leonard – Special Presentation: Stanford Childx Conference

TL;DR

Chronic diseases in children can have long-term effects on bone health and muscle function, leading to increased risk of fractures and impaired physical fitness.

Transcript

Another relatively new faculty member here, although not as new as Gary, is Mary Leonard. Mary is a professor of pediatrics and medicine, and she's also been appointed as the Associate Dean for Maternal Child Health Research, and she co-lead Spectrums Child Health at Stanford. She's a pediatric nephrologist and directs the Bone and Health and Nutri... Read More

Key Insights

• 🥺 Chronic diseases in children can have long-lasting effects on bone health and muscle function, leading to an increased risk of fractures and impaired physical fitness.
• ☠️ Risk factors for poor bone accrual in children with chronic diseases include malnutrition, immobility, muscle deficits, delayed puberty, obesity, and certain therapies.
• ☠️ Challenging the sedentary lifestyle of children with chronic diseases and implementing exercise interventions can help improve bone health and muscle function.

Questions & Answers

Q: How does chronic kidney disease affect bone health in children?

Chronic kidney disease in children can lead to small and weak bones, even after kidney transplantation. These children have an increased risk of fractures, and this risk continues into young adulthood.

Q: What are some risk factors for poor bone accrual in children with chronic diseases?

Risk factors for poor bone accrual in children with chronic diseases include malnutrition, immobility, muscle deficits, delayed puberty, and certain therapies like prednisone and radiation therapy. These factors can disrupt normal bone development and increase the risk of osteoporosis.

Q: How does physical activity impact bone health in children?

Physical activity plays a crucial role in promoting bone health in children. Biomechanical loading, such as that experienced during exercise, stimulates bone formation and improves bone strength. Children with chronic diseases often have limited physical activity, which can further contribute to poor bone health.

Q: Are there any reversible interventions to improve bone health in children with chronic diseases?

Some interventions, such as monoclonal antibodies targeting TNF alpha in children with Crohn's disease, have shown promising results in improving bone health. However, these interventions are most effective when implemented during puberty and require further research.

Summary & Key Takeaways

• Mary Leonard, a professor of pediatrics and medicine, discusses the impact of chronic diseases on bone health and muscle function in children.

• Chronic diseases such as inflammatory bowel disease, chronic kidney disease, and cystic fibrosis can lead to poor bone accrual and muscle deficits.

• Risk factors for bone and muscle deficits in children with chronic diseases include malnutrition, immobility, obesity, growth failure, delayed puberty, and certain therapies.
