VITAMIN D-BINDING PROTEIN LEVELS IN FEMALE PATIENTS WITH PRIMARY HYPERPARATHYROIDISM
2013
Objective: To determine whether low levels of vitamin D-binding protein (DBP) are related to 25-hydroxyvitamin D (25[OH]D) deficiency in female patients with primary hyperparathyroidism (PHPT).Methods: Twenty-five female patients with PHPT (serum calcium level >10.2 mg/dL and intact parathyroid hormone (iPTH) level >66 pg/mL) and 25 healthy age- and body mass index-matched female control subjects were xaminod. Serum calcium and iPTH levels were determined by commercial laboratories. Levels of 25(OH)D and 1,25-dihydroxyvitamin D (1,25[OH]2D) were determined by radioimmunoassay, and DBP level was determined by enzyme-linked immunosorbent assay.Results: Serum iPTH and calcium levels were higher in PHPT patients than control subjects (P<.001). Levels of 25(OH)D, albumin, and DBP were lower in the serum of PHPT patients than control subjects (P<.01). There were no significant differences in 1,25(OH)2D and free 25(OH)D levels between PHPT patients and control subjects. DBP level was inversely correlated with ca...
