Fibroblast growth factor 23 (FGF23) is a regulator of phosphate and vitamin D homeostasis that carries out primary bone- and mineral-related physiological functions to increase renal phosphate excretion and reduce 1α-hydroxylation of 25-hydroxyvitamin D. In a negative endocrine feedback loop, 1,25-dihydroxyvitamin D also stimulates FGF23 secretion. Previous studies have assessed the correlation between vitamin D receptor activator therapy and FGF23 concentrations, and to our knowledge, none has assessed the correlation between intravenous (i.v.) maxacalcitol therapy and FGF23 concentration in hemodialysis patients. Subjects included 148 patients on maintenance hemodialysis. Serum FGF23 concentrations were measured. The correlations among serum FGF23 concentrations with i.v. maxacalcitol therapy and other clinical parameters and medications were analyzed. Mean serum log FGF23 was 3.7 ± 0.8 pg/mL. After division into two equal groups based on median serum log FGF23 level, the percentages of patients administered i.v. maxacalcitol (60/74 [81.1%] vs. 45/74 [60.8%], p0.01) were significantly higher in the high log FGF23 group. The amounts of serum FGF23 concentrations had been significantly higher to the amounts of i.v. maxacalcitol per week dependency. Multivariate regression analysis showed that treatment with i.v. maxacalcitol was an independent predictor of serum FGF23 levels, regardless of phosphate or calcium concentrations. i.v. maxacalcitol correlates with serum FGF23 concentration in hemodialysis patients, independent of serum phosphate or calcium concentrations. |
