Hyperparathyroidism is a potentially serious complication in patients with advanced renal insufficiency (1). As renal mass dwindles and phosphate excretion gets more difficult, synthesis of 1,25-dihydroxycholecalciferol is impaired, and concentrations of fibroblast growth factor-23 increase (2), leading to low serum calcium concentrations and an initially appropriate response of the parathyroids: parathyroid hormone (PTH) synthesis increases. Subsequently, however, parathyroid hypertrophy gradually develops. After a period of time, the calcium-sensing receptor is reset, the calcium × phosphate product increases, soft tissues and vessels become calcified, and …
