Fibroblast growth factor 23 (FGF23) is part of a previously unrecognized hormonal bone-parathyroid-kidney axis, which is modulated by PTH, 1,25 (OH)(2)-vitamin D (1,25 (OH)(2) D), dietary and serum phosphorus levels.

Although bone has long been recognized as a target for hormones influencing calcium and phosphorus homeostasis and bone structure, recent evidence shows that the skeleton itself produces at least two hormones, fibroblast growth factor 23 (FGF23) and osteocalcin.

Recent studies have demonstrated that levels of fibroblast growth factor 23 (FGF-23), a key regulator of phosphorus and vitamin D metabolism, rise dramatically as renal function declines and may play a key initiating role in disordered mineral and bone metabolism in patients with chronic kidney disease (CKD).

Similarly, in FGFR4 (-/-) mice, administration of FGF23 caused a small but significant decrease in serum phosphorus levels (8.7 +/- 0.3 vs. 7.6 +/- 0.4 mg/dl; p < or = 0.001) and in renal BBM NaPi-2a and NaPi-2c protein abundance.

In the past 5 years, with the publication of several randomized controlled trials, large observational studies, and smaller clinical series, significant progress has been made in our understanding of mineral metabolism, calcium and phosphorus management, and the use of activated vitamin D irrespective of parathyroid hormone level in chronic kidney disease.
More recently, fibroblast growth factor-23 and serum alkaline phosphatase have been shown to predict mortality in dialysis patients, making these attractive markers to monitor.

Hypercalcemia and hyperphosphatemia have long been known to play a major role in the occurrence of vascular and other soft tissue calcification in patients with CKD, together with endocrine disturbances including vitamin D, parathyroid hormone, fibroblast growth factor-23, and klotho.
It remains to be demonstrated in prospective randomized trials whether normalization of serum phosphorus and/or calcium leads to better patient outcome.

However, in the presence of low calcium, high phosphorus, vitamin D deficiency, and uremia, PT cells leave quiescence.
Furthermore, recent studies indicate that the fibroblast growth factor-23 may play a central role in the regulation of phosphate-vitamin D metabolism in CKD.

Perhaps even more important, the discovery of fibroblast growth factor 23 (FGF23) and its potential as a novel diagnostic to identify disordered phosphorus metabolism at an early, subclinical state has presented the opportunity to develop placebo-controlled randomized trials in pre-dialysis CKD patients with normal serum phosphate levels.
