Novel hormones related to the calcium and phosphate homeostasis in kidney disease

Calcium and phosphate levels are regulated by a complex interplay between parathyroid hormone (PTH), calcitriol, fibroblast growth factor 23 (FGF23) and its co-receptor αKlotho. Kidney failure causes severe disturbances in the mineral and bone homeostasis resulting in phosphate retention, hypocalcaemia and high plasma levels of FGF23 and PTH, and the patients develop fragile bones and vascular calcifications. Today’s treatments aim to lower the levels of phosphate and PTH. Future studies need to clarify, if lowering the FGF23 level or supplementation with αKlotho will improve survival for patients with chronic kidney disease.
