title: The effects of phosphate and vitamin D therapy on osteopenic, hypophosphatemic osteomalacia of childhood.
abstract: Two severely osteopenic adolescent males with clinical manifestations of adult onset hypophosphatemic osteomalacia were resistant respectively to physiological and pharmacological doses of vitamin D. Clinical improvement ensued following initiation of pharmacological doses of vitamin D and phosphate. Non-decalcified bone biopsies obtained before and during therapy exhibited correction of an isolated mineralization in the second. The response to treatment was reflected in striking changes in tetracycline-labelled calcification fronts in both patients.
