Filter by:The primary objective of this study is to assess the safety of an investigational intravenous iron (ferric carboxymaltose [FCM]) or an equal dose of iron dextran and explore the mechanism of hypophosphatemia following administration of FCM or that of an equal dose of iron dextran when treating women with iron deficiency anemia due to heavy uterine bleeding (HUB).
The purpose of the study is to do a follow-up survey of all individuals with hereditary hypophosphatemia in Norway, focusing on manifestations in childhood and adolescence. The investigators also want to study phenotype-genotype associations, and look for new genes, in all forms of hereditary hypo and hyperphosphatemia.
The purpose of the study is to determine whether cinacalcet, used in patients with secondary hyperparathyroidism to control excessive parathyroid hormone, can normalize low blood phosphorus that is commonly seen in patients who have had a kidney transplant.
Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.
The primary objective of this study is to assess the safety and tolerability of KRN23 after a single intravenous (IV) and subcutaneous (SC) administration in XLH patients.
Introduction: Based on our experience with calcitonin as an FGF-23 suppressive agent in a patient with an FGF-23 producing tumor we hypothesize that calcitonin may be a physiologically important regulator of FGF-23 production and secretion in healthy humans. Aim: In this study we wish to examine the FGF-23 suppressive effects of calcitonin in healthy men. Study Design: placebo-controlled, cross-over study Method: - All twelve subjects are examined on two occasions, once after exposure to placebo 1 ml NaCl 0.9% subcutaneously, and once following calcitonin 200 IU/ml subcutaneously - On both occasions frequent bloodsampling will take place, out an indwelling catheter in de forearm vein. - Sampling times: -15, 0, 60, 120, 240, 360, and 480 minutes - Mealtimes: Calcium and Phosphate intake standardized on both occasions - All samples are analyzed for FGF-23, using a C-terminal FGF-23 ELISA kit (Immunotopics, San Clemente, USA) that measures intact and C-terminal fragments of FGF-23, and one that measures only intact FGF-23 - Samples obtained at T-15, T0, T240 and T480 are stored for later analysis of Ca, albumin, PO4, PTH, 25-OHD and 1,25-OHD Endpoint: A change of 25% in de serum FGF-23 levels in response to a single subcutaneous injection of calcitonin 200 IU.
The purpose of this study is to: 1. To elucidate the mechanism involved in the sorafenib-induced hypophosphatemia and possible early effect of hypophosphatemia on bone mineral density 2. A secondary objective to assess the effect sorafenib treatment on evaluate left ventricular function (LVEF) and Beta-type natriuretic peptide in plasma.
The purpose of this study is to determine the effectiveness of paricalcitol, a form of synthetic vitamin D, in lowering parathyroid hormone (PTH) levels and reducing disease symptoms in children and adults with X-linked hypophosphatemic (XLH) rickets.
