Effect of secondary hyperparathyroidism treatment with cinacalcet on selected adipokines and markers of endothelial injury in hemodialysis patients: a preliminary report

INTRODUCTION Disturbances in endothelial function, adipokines, and mineral metabolism due to secondary hyperparathyroidism (SHPT) shorten the lifespan in hemodialysis (HD) patients. 
OBJECTIVES The aim of the study was to evaluate the effect of SHPT treatment with cinacalcet on selected adipokines and markers of endothelial injury in HD patients.
PATIENTS AND METHODS Soluble thrombomodulin (sTM), E-selectin, leptin, and adiponectin levels were measured in patients with SHPT at baseline and at 6 months of cinacalcet treatment.
RESULTS A total of 18 patients completed the study. SHPT treatment with cinacalcet decreased calcium, phosphate, and intact parathormone (iPTH) levels; however, no significant changes in sTM, E-selectin, leptin, or adiponectin were observed. iPTH levels after treatment correlated with age (r = –0.51, P = 
0.031), mean cinacalcet dose (r = 0.65, P = 0.004), as well as baseline calcium (r = 0.65 P = 0.003), iPTH (r = 0.59, P = 0.01), E-selectin (r = 0.56, P = 0.016), and leptin (r = –0.49, P = 0.039). 
CONCLUSIONS Cinacalcet treatment does not affect the markers of endothelial function and selected adipokines. Effectiveness of treatment may be modulated by E-selectin and leptin.
