Insights
Kidney transplantation positively impacts pediatric growth, improving height and BMI. Bone formation markers increased, indicating favorable bone acquisition after transplantation.
Area of Science:
- Pediatric Nephrology
- Endocrinology
- Bone Metabolism
Background:
- Kidney transplantation is crucial for pediatric patients with end-stage renal disease.
- Long-term effects on growth and skeletal development require further investigation.
Purpose of the Study:
- To evaluate growth and skeletal development in pediatric kidney transplant recipients over three years.
- To assess changes in bone metabolism markers, parathyroid hormone (PTH), and vitamin D levels.
Main Methods:
- Prospective study of pediatric patients (3.4-15.0 years) post-kidney transplantation.
- Serial assessments of growth (height SDS, BMI SDS), body composition, bone mineral density (BMD), bone turnover markers (CTX, TRACP5b, PINP, ALP, osteocalcin), PTH, and vitamin D.
- Measurements taken at baseline, 3, 12, and 36 months post-transplant.
Main Results:
- Significant increases in height SDS (from -1.7 to -1.1) and BMI SDS (from -0.1 to 0.6) over 3 years.
- Increased fat and lean mass, with total body bone mineral content (BMC) increasing.
- Decreased bone resorption markers initially, followed by increased bone formation markers over time.
- No significant changes in total BMD observed.
Conclusions:
- Kidney transplantation promotes favorable growth and bone acquisition in pediatric patients.
- Improved height and BMI, along with enhanced bone formation, suggest positive long-term skeletal health outcomes.
Abstract:
This prospective study investigated growth and skeletal development for 3 years after kidney transplantation in pediatric patients, 3.4-15.0 years of age. Growth, BMD, bone resorption markers (CTX and TRACP5b), bone formation markers (PINP, ALP, and osteocalcin), PTH, and vitamin D were assessed at start, 3, 12, and 36 months after transplantation. Median GFR was 63 (range 37-96) mL/min/1.73 m2 after 3 years. The median height SDS increased from -1.7 to -1.1, and median BMI SDS increased from -0.1 to 0.6 over 3 years, which shows that transplantation had a favorable outcome on growth. Fat mass increased after transplantation at all time points, whereas lean mass increased after 1 year and 3 years. Total BMC increased at all time points. No changes were observed for total BMD. Bone resorption markers decreased initially after 3 months and remained stable throughout the study, whereas the bone formation markers decreased initially, but successively increased over the study period. In conclusion, this study demonstrates that height SDS and BMI SDS increased, along with the increased formation markers that reveal a positive bone acquisition after kidney transplantation, which was reflected by the significant increase in total body BMC.
