Vitamin Dresistant Rickets
Also called familial hypophosphatemia, this isan X-linked hereditary disorder characterized by hypophosphatemia (usually <2.5 mg/dl), inappropriate phosphaturia (phosphate/creatinine clearance ratio >0.25), rachitic bone disease, and Pnormal serum calcium and PTH levels. The primary defect is not known, but a decrease in intestinal calcium and phosphate absorption accompanies the renal phosphate “leak.” Vigorous treatment with both high doses of vitamin D (20,000 to 50,000 IU/day) and oral phosphate is required to heal the rachitic bone lesions.
