Uncertainties exist regarding whether FGF-23 production is influenced by PTH and its involvement in bone formation. We evaluated FGF-23 response and its relation to changes in biomarkers of bone formation following intermittent PTH treatment. Twenty-seven women with a mean [SD] age of 75.8 [5.4] years with postmenopausal osteoporosis were treated with PTH(1-34) for 18 months. Bone mineral density (BMD) was measured at 6 and 18 months at the lumbar spine (LS) and total hip (TH). Blood samples were obtained at baseline, 1-3, 6-9, and 12-18 months. Serum calcium, phosphate, PTH, 25(OH)vitamin D, 1,25(OH)(2)vitamin D, markers of bone turnover, FGF-23, and sclerostin were measured. BMD increased at both the LS (11.6%, P < 0.001) and TH (2.5%, P < 0.01). The bone formation marker P1NP increased early (baseline mean [SD] 39.9 [24.4] ?g/l, 1-3 months 88 [37.9] ?g/l; P < 0.001) and remained higher than baseline throughout 18 months. FGF-23 also increased, with a peak response at 6-9 months (increase 65%, P = 0.002). Serum phosphate remained stable. A significant increase in 1.25(OH)(2)vitamin D (P = 0.02) was seen at 1-3 months only. A small but significant reduction in sclerostin was seen at 6-9 (P = 0.02) and 12-18 months (P = 0.06). There was a positive correlation between changes in P1NP and FGF-23 (6-9 months r = 0.78, P < 0.001). FGF-23 is increased by intermittent PTH(1-34). This is related to early changes in P1NP, suggesting that the skeletal effects of PTH may involve FGF-23. Further studies are required to elucidate this.
