analysis of paired serum samples ( mean +/- se ) in 13 patients during euglucocorticoidism and during hyperglucocorticoidism showed that glucocorticoid excess resulted in small decreases of plasma 25-hydroxy-vitamin d concentrations ( 22 +/- 2- 18 +/- 2 ng/ml ; p < 0.05 ) but no significant changes in plasma 1,25-dihydroxyvitamin d ( 32 +/- 8- 23 +/- 6 pg/ml ) or serum immunoreactive parathyroid hormone ( 21 +/- 2- 18 +/- 2 muleq/ml ) .
