Abstract
A successful kidney transplantation (Tx) offers good quality of life for children suffering from chronic renal failure. However, some metabolic abnormalities may not be corrected and may persist after Tx despite good graft function.
Post-Tx bone disease seems to be a universal finding in adult Tx recipients, and is most probably related to steroids. Reports on bone mineral density (BMD) in children after renal Tx are not uniform.
Recent studies suggest that BMD is normal when corrected for height. However, longitudinal studies show a transient decrease in BMD in the early post-Tx period.
These controversial results raise the issue of the correct interpretation of dual-energy X-ray absorptiometry in children with stunted growth. Etiopathogenetic factors of the decreased BMD, preventive and therapeutic measures are discussed.
In conclusion, the results of dual energy X-ray absorptiometry should be interpreted with caution, especially in children with disturbed growth.
