The response of plasma aldosterone (PA) and plasma renin activity (PRA) to ACTH stimulation (0.25 mg Tetracosactide infusion/10 h) and to insulin-induced hypoglycemia (0.1 U/kg b.w.) has been studied in 34 essential hypertensive (EH) patients. Corticotrophin stimulation increases significantly PA, the percent increase being higher in normal PRA EH patients than in controls but comparable to controls in low PRA EH patients. PRA shows a slight and transient elevation. A significant increase in PA is observed also during the insulin test, but the percent increase is lower than that under ACTH stimulation. The possibility that aldosterone is involved, under severe and frequent stress, in the genesis of essential hypertension is discussed.

Investigations were carried out on the behavior of 18-hydroxy-11-deoxycorticosterone (18-OH-DOC) in essential hypertension (EH) under exogenous administration of synthetic ACTH and insulin. 40 stable EH patients and 21 normal subjects were included in the study. The increase (12-fold basal values) in plasma 18-OH-DOC in normal subjects under Tetracosactide was significantly higher than cortisol (4-fold basal values). Furthermore, insulin hypoglycemia increased 18-OH-DOC levels 5-fold, whilst basal values of cortisol were increased 2-fold. An increase in 18-OH-DOC and cortisol was also observed in EH patients: in the subgroup with normal and low plasma renin activity, however, the rise in these two steroids was significantly lower than in normal subjects both under Tetracosactide and insulin. No significant hormonal modifications were observed after furosemide administration either in the normal subjects or in the EH patients. 18-OH-DOC by itself does not, therefore, appear to play a pathogenetic role in EH.
