title: Diurnal 18-hydroxy-11-deoxycorticosterone pattern in human stable hypertension.
abstract: Diurnal 18-hydroxy-11-deoxycorticosterone (18-OH-DOC) pattern was studied with RIA technique in 33 hypertensive patients in supine position and on normal sodium diet. The compound was evaluated every 2 h from 0800-2000 h. Simultaneously, plasma aldosterone and cortisol were measured. Abnormal 18-OH-DOC behavior was observed in only 2 out of 4 patients with Cushing's disease, while sporadic and slight elevations, synchronous with F, were seen in 5 out of 24 stable essential hypertensive patients [1 with normal plasma renin activity (PRA), 1 with low PRA, and 3 with high PRA]. 18-OH-DOC was normal in 2 cases of hypertension due to renal artery stenosis, in 1 patient with nephrosclerosis, and in 1 patient with horseshoe kidney. From these results, 18-OH-DOC does not seem to play an important pathogenetic role in stable essential hypertension, considering also the low mineralocorticoid activity of the compound.
