Evaluation of Serum Level of FGF23 and 1,25(OH)2D3 in Primary Hyperparathyroidism Patients Before and After Parathyroidectomy.

Although 1,25(OH)2D3 and FGF23 levels were preoperatively higher in PHPT, their variations were not meaningful. There was a statistically direct significant relationship between 1,25(OH)2D3 and FGF23 preoperatively and postoperatively; however, the correlations between FGF23 and calcium, phosphate, and PTH were not significant.
