[Secondary hyperparathyroidism in hospitalized aged patients: apropos of 200 assays of intact parathyroid hormone].
Plasma intact parathyroid hormone (PTH) determinations were performed in 200 elderly patients admitted in a geriatric care unit. Abnormally high levels of PTH were observed in 40 subjects. There was a significant correlation between plasma ionized calcium determinations or creatinine clearance and PTH levels. Subjects with high PTH levels exhibited constantly reduced levels of 25 OH-D3. A calcium and vitamin D supplement, performed in 13 patients, was constantly followed by a decrease of the PTH level.
