title: [Fibroblast growth factor (FGF)-23 in patients with hypoparathyroidism].
abstract: Hypoparathyroidism is a well-described cause of hyperphosphatemia. We aimed to clarify the physiological role of FGF-23 in serum phosphate homeostasis in hypoparathyroidism after thyroidectomy. Increased serum FGF-23 levels were found in patients with hyperphosphatemia and hypocalcemia, caused by hypoparathyroidism after thyroidectomy. After the recovery of parathyroid function, the serum level of calcium, phosphate, and FGF-23 was normalized. Serum FGF-23 levels were significantly higher in patients with permanent hypoparathyroidism than in healthy controls. These results indicate that FGF-23 may play an important role in serum phosphate homeostasis by its up-regulation in the hyperphosphatemic condition.
