Healing of rickets with phosphate supplementation in the hypophosphatemic male mouse.

Healing of Rickets with Phosphate Supplementation

is characterized by low serum phosphorus concentration due to increased urinary phosphate excretion, rickets, osteomalacia, and dwarfism. Because phosphate administration can heal rickets but not osteomalacia in the human disease, we have compared the effect ofphosphate supplementation on the epiphyseal and endosteal bone mineralization in the mutant animal. Phosphate was given in drinking wate...

Hypophosphatemic rickets with hypercalciuria.

Tertiary hyperparathyroidism during high phosphate therapy of familial hypophosphatemic rickets.

We report the development of severe tertiary hyperparathyroidism in three girls treated for familial hypophosphatemic rickets and characterize parathyroid function in vivo and in vitro. All patients had been previously treated with relatively large doses of inorganic phosphorus (125 mm/day) and ergocalciferol or calcitriol for several years and had radiographic evidence of long-standing hyperpa...

Hereditary hypophosphatemic rickets

Hereditary hypophosphatemic rickets (HHR) are a group of diseases characterized by renal phosphate wasting causing growth retardation, rickets and osteomalacia. The most common form is the X-linked dominant hypophosphatemic rickets caused by inactivating mutations in the PHEX gene. The other hereditary hypophosphatemic syndromes present a lower prevalence. These include autosomal dominant hypop...

Hypophosphatemic rickets and osteomalacia.

The hypophosphatemic conditions that interfere in bone mineralization comprise many hereditary or acquired diseases, all of them sharing the same pathophysiologic mechanism: reduction in the phosphate reabsorption by the renal tubuli. This process leads to chronic hyperphosphaturia and hypophosphatemia, associated with inappropriately normal or low levels of calcitriol, causing osteomalacia or ...
