In these two patients whose plasma concentration of PTH was normal (determined by radioimmunoassay). neither vitamin D nor phosphate therapy had been given during the past 10 yr. Two normal men and a hypophosphatemic man with intestinal malabsorption, hypocalcemia, and osteomalacia served as control subjects.
Levels correlated with those of other indices of bone turnover (BGP r = 0.82, p less than 0.005; urine total HP r = 0.60, p less than 0.025; urine free HPr = 0.78, p less than 0.005), but were not related to the degree of osteomalacia found on bone biopsy.
