because serum 1,25-dihydroxyvitamin d levels are inappropriately low in these patients and high calcitriol concentrations may be required to heal the osteomalacia , we chose to treat five affected subjects with high doses of calcitriol ( 68.2 +/- 10.0 ng/kg total body weight/d ) and supplemental phosphorus ( 1-2 g/d ) performing metabolic studies and bone biopsies before and after 5-8 mo of this therapy in each individual .
