Calcitriol in the Management of Secondary Hyperparathyroidism of Renal Failure

Abstract

Secondary hyperparathyroidism (HPT) is characterized by persistent hypersecretion of parathyroid hormone (PTH), and produces characteristics of hyperparathyroid bone disease and a variety of biochemical and hormonal derangements. Management of uremic secondary HPT involves both prevention and treatment. Among preventive measures are attempts to control serum phosphate and serum calcium concentrations through dietary restriction, administration of phosphate binders, and calcium supplementation. Treatment with a vitamin D analog such as calcitriol returns plasma calcium concentrations toward normal and suppresses PTH secretion. The availability of a parenteral formulation of calcitriol, and new information regarding alternative routes of administration and regimens employing oral pulse dosing have renewed interest in calcitriol for the management of uremic secondary HPT.

Subtotal Parathyroidectomy in Renal Failure: Still Needed after All These Years

“…Tight control of phosphate and calcium levels by dialysis and medications has been shown to decrease parathyroid hormone (PTH) levels. A major change has been the routine administration of calcitriol (1,25-dihydroxyvitamin D), which inhibits parathyroid cell hyperplasia, suppresses parathyroid hormone secretion, and increases calcium absorption [4,5].…”
