We aimed to determine the effect of vitamin D replacement therapy on serum FGF-23 concentrations in vitamin D deficient women and to compare the FGF-23 concentrations of vitamin D deficient patients with healthy subjects and patients with genetically-determined hypophosphatemic rickets.
Study group was composed of vitamin D deficient females (n =18, mean age 29.1±9.9 yrs), vitamin D sufficient healthy females (control group; n = 19, mean age 28.5±5.2 yrs) and patients with genetically-determined hypophosphatemic rickets (n=13, mean age 26.5±15.1 yrs). Groups were compared for serum FGF-23, 1,25 dihydroxy vitamin D3, calcium, phosphate, bone turnover markers, intact parathyroid hormone and urinary excretion of calcium and phosphate. Vitamin D deficient group was re-evaluated after a standard treatment regimen.

The purpose of the study is to assess the efficacy and safety of KRN23 administered subcutaneously once every 2 weeks in children with X-linked hypophosphatemic rickets/osteomalacia(XLH)
The researchers are trying to evaluate a newer imaging technique (Ga-DOTATATE PET/CT) to see if it is more sensitive to localize the source of the hormone, which has caused the low phospha...
The purpose of the study is to evaluate the efficacy and safety of KRN23 after its 48-week once every 4 weeks repeated subcutaneous administration to Japanese and Korean patients with Tumo...
UX023-CL304 is a Phase 3 open-label, single-arm, multicenter study to establish the effects of KRN23 on bone quality and osteomalacia associated with XLH. Approximately 10 adult subjects w...
UX023T-CL201 is an, open-label, Phase 2 study. The study will be conducted in adults aged 18 years or older with TIO or ENS whose tumor/skin lesion is inoperable to assess the efficacy and...
FGF23 is a hormone that reduces blood phosphate level. Excessive actions of FGF23 result in several kinds of hypophosphatemic rickets/osteomalacia such as X-linked hypophosphatemic rickets and tumor-i...
Osteomalacia is a bone disease caused by impaired skeletal mineralization. Vitamin D dependent types have to be distinguished from hypophosphatemic forms. Typical signs and symptoms include diffuse ...
Fibroblast growth factor 23(FGF23)is a phosphaturic hormone, and its excess causes several kinds of congenital and acquired hypophosphatemic diseases. A combination of oral active vitamin D3 and phosp...
Tumor-induced osteomalacia is a fibroblast growth factor 23(FGF23)-related hypophosphatemic disorder caused by FGF23 producing tumor. TIO represents bone pain, fracture/pseudofracture, muscle weakness...
Denosumab, a novel agent that inhibits osteoclasts, reduces the risk of fracture in patients with osteoporosis. However, worsening of hypophosphatemia and other symptoms may be induced by denosumab in...
A disorder characterized by HYPOPHOSPHATEMIA; RICKETS; OSTEOMALACIA; resulting from lack of phosphate reabsorption by the kidneys and possible defects in vitamin D metabolism.
A condition marked by softening of the bones (due to impaired mineralization, with excess accumulation of osteoid), with pain, tenderness, muscular weakness, anorexia, and loss of weight, resulting from deficiency of vitamin D and calcium. (Dorland, 27th ed)
A hereditary disorder characterized by HYPOPHOSPHATEMIA; RICKETS; OSTEOMALACIA; renal defects in phosphate reabsorption and vitamin D metabolism; and growth retardation. Autosomal and X-linked dominant and recessive variants have been reported.
A condition of an abnormally low level of PHOSPHATES in the blood. Severe hypophosphatemia (below 1 mg/liter) can affect every organ in the body leading to HEMOLYSIS; LASSITUDE; SEIZURES; and COMA. Chronic hypophosphatemia can lead to MUSCLE WEAKNESS; and bone diseases, such as RICKETS and OSTEOMALACIA.
The major circulating metabolite of VITAMIN D3. It is produced in the LIVER and is the best indicator of the body's vitamin D stores. It is effective in the treatment of RICKETS and OSTEOMALACIA, both in azotemic and non-azotemic patients. Calcifediol also has mineralizing properties.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
