[Treatment of secondary hyperparathyroidism in hemodialysed patients--paricalcitol with or without cinacalcet].

Abstract

Secondary hyperparathyroidism (sHPT) is a common complication being a consequence of metabolic disorders associated with chronic kidney disease (CKD). Treatment of the sHPT should lead to calcium-phosphate management stabilization and parathyroid hormone levels reduction. The phosphate binders, synthetic vitamin D analogs and calcimimetics are used in sHPT treatment. In this paper we analyzed the results of three month paricalcitol treatment of 36 hemodialysis patients with sHPT (serum iPTH> 500 pg/ml). 11 patients have additionally received cinacalcet. Analysis of the results showes a statistically significant reduction in iPTH and alkaline phosphatase. Paricalcitol is effecitve in the tratment of SHPT with favourable profile of side effects. Alcaline phosphatase reduction may be a desirable additional therapeuctic effect. However, it appears that combined therapy with paricalcitol and cinacalcet shoud be offered to selected population of patients i.e. with hypocalcemia after calcimimetics.
