Growth potential and skeletal maturity in children with chronic renal insufficiency
Insights
Growth potential in boys with chronic renal insufficiency decreases with age. Bone age delay is most pronounced in those with early-onset disease, impacting clinical management and post-transplant growth interpretation.
Area of Science:
- Pediatric Nephrology
- Growth and Development
- Skeletal Maturation
Background:
- Chronic renal insufficiency (CRI) significantly impacts growth in children.
- Assessing growth potential is crucial for managing pediatric kidney disease.
- Understanding factors influencing growth is vital for predicting outcomes, including post-transplant height.
Purpose of the Study:
- To determine the growth potential of boys with varying degrees of chronic renal insufficiency.
- To evaluate the relationship between bone age, chronological age, and growth potential.
- To assess the relevance of growth potential in interpreting height changes after renal transplantation.
Main Methods:
- Assessed growth potential in 27 boys with chronic renal insufficiency.
- Utilized height centiles relative to bone age and chronological age.
- Monitored bone age advancement in relation to disease severity and growth arrest.
Main Results:
- Growth potential diminishes with increasing chronological age.
- Bone age delay was greatest in children with disease onset in infancy.
- Bone age advanced despite severe osteodystrophy and growth arrest.
- Bone age delay did not correlate with current renal function status.
Conclusions:
- Serial bone age determination is essential for managing children with chronic renal failure.
- Knowledge of growth potential aids in interpreting height velocity after renal transplantation.
- Growth potential is a key factor in the long-term management of pediatric kidney disease.
Abstract:
The growth potential of 27 boys with varying degrees of chronic renal insufficiency has been determined from their present height centile for both bone age and chronological age. With increasing age their growth potential diminishes. The delay in bone age is greatest in those children whose disease dates from infancy, but does not correlate with their present state of renal function. Bone age continues to advance in the presence of severe osteodystrophy and growth arrest. Knowledge of the growth potential of children with chronic renal failure is of relevance in interpreting the height increments observed following renal transplantation. Serial determination of bone age is therefore an important aspect of their clinical management.
