title: Prevention and treatment of renal osteodystrophy in children with chronic renal insufficiency and end-stage renal disease.
abstract: Histologic features associated with secondary hyperparathyroidism remain the predominant skeletal lesion in adults and children with chronic renal failure. When instituted early, vitamin D therapy has been shown to ameliorate the development and progression of the biochemical, radiographic, and histologic evidence of secondary hyperparathyroidism in patients with chronic renal insufficiency. Aggressive parathyroid hormone suppression, however, has led to the increased prevalence of adynamic bone. Adynamic bone has been attributed partly to aggressive calcitriol therapy, administration of high amounts of exogenous calcium either as a phosphate binding agent or during dialysis therapy, presence of diabetes, older age, or previous parathyroidectomy. Several vitamin D analogues are currently being evaluated in patients with chronic renal failure to prevent complications associated with calcitriol therapy. In addition, calcium-free phosphate binding agents and the use of calcimimetic drugs may play a significant role in the effective management of secondary hyperparathyroidism in children with chronic renal failure.
