[Measurement of plasma 1,25 dihydrovitamin D. Normal and pathological values in adults (author's transl)].
Plasma levels of 1,25 dihydrovitamin D (1,25 (OH)2D) were measured in normal subjects and in patients with various diseases, using a radiocompetition method. Mean values of 89 +/- 58 pmol/l (1 s.d.) were found in normal adults, irrespective of sex. Plasma 1,25 (OH)2D values were high in 12/31 patients with lithiasis and hypercalciuria, in 1/7 patients with lithiasis and normal calciuria and in 2/4 patients with idiopathic parathyroid adenoma; they were normal in 2 patients with essential hypoparathyroidism. 1,25(OH)2D was undetectable in 5 patients with chronic renal failure, low in 7 and normal in 4. Following successful kidney transplantation (serum creatinine less than 120 mumol/l) one-half of the patients had normal values and the other half high values.
