[Hormonal regulation of phosphorus and calcium metabolism at the kidney level].

The effects of hormones in the renal handling of calcium and phosphate are reviewed in the context of transport events occurring in different segments of the nephron. Hormones that influence the renal handling of calcium include parathyroid hormone, calcitonin and vitamin D. However, the kidney plays only a minor role in the maintenance of calcium balance. Hormones that modify the renal handling of phosphate are parathyroid hormone, thyroid hormone, growth hormone, glucocorticoids and vitamin D. In contrast to calcium, the kidney plays an important role in the maintenance of phosphate balance. In this endocrine context the contribution of the kidney is reviewed in clinical conditions of hypo- and hyperphosphatemia.
