Fibroblast growth factor 23 (FGF-23) plays causative roles in the development of several hypophosphatemic rickets/osteomalacia such as X-linked hypophosphatemic rickets/osteomalacia (XLH) and tumor-induced rickets/osteomalacia. Patients with hypophosphatemic rickets/osteomalacia often complain of muscle weakness and bone pain that severely affect daily activities of these patients. The purpose of this study was to examine whether anti-FGF-23 antibodies, which have been shown to improve hypophosphatemia and rachitic changes of juvenile Hyp mice in a murine model of XLH, also ameliorate hypophosphatemic osteomalacia and affect muscle force and spontaneous motor activity in adult Hyp mice. Repeated injections of anti-FGF-23 antibodies increased serum phosphate and 1,25-dihydroxyvitmain D levels and enhanced mineralization of osteoid in adult Hyp mice, whereas bone length did not change. We found that grip strength was weaker and that spontaneous movement was less in adult Hyp mice than in wild-type mice. In addition, FGF-23 antibodies increased grip strength and spontaneous movement. These results suggest that the inhibition of excess FGF-23 action not only ameliorates hypophosphatemia and impaired mineralization of bone but also improves muscle weakness and daily activities of patients with FGF-23-related hypophosphatemic rickets/osteomalacia.
