The management of secondary hyperparathyroidism is of crucial importance in the treatment of end stage renal disease (ESRD) patients.

Abstract

The management of secondary hyperparathyroidism is of crucial importance in the treatment of end stage renal disease (ESRD) patients. In particular, hypercalcemia, hyperphosphatemia, and elevated calcium x phosphate (Ca x P) product should be taken into consideration during administration of vitamin D metabolites for the control of PTH secretion. During the last 10 years, many authors have been studying the efficacy of new non-calcemic vitamin D analogs on suppressing secondary hyperparathyroidism in ESRD patients. In this brief review, we analyzed three new vitamin D analogs: 22-oxacalcitriol (Maxacalcitriol), 19-nor-1a, 25(OH)2D2 (Paracalcitriol), and 1a (OH)2D2 (Doxacalciferol). In addition, calcimimetic agents may represent a new pharmacologic choice to the treatment of secondary hyperparathyroidism, binding parathyroid calcium sensing receptors (CaSR) and reducing PTH secretion. These compounds may represent an important tool for the treatment of both secondary hyperparathyroidism and soft tissue calcifications in ESRD patients. In conclusion, a combined use of non calcemic phosphate binders, new vitamin D analogs and calcimimetics should be seriously considered to further improve the already known therapy of secondary hyperparathyroidism in ESRD patients.
