Yasuda G, Shionoiri H, Umemura S, Takasaki I, Ishii M. Exaggerated blood pressure response to angiotensin II in patients with Cushing's syndrome due to adrenocortical adenoma. Eur J Endocrinol 1994:131:582–8 ISSN 0804–4643 We studied the roles played by the renin-angiotensin system in inducing hypertension in nine patients with Cushing's syndrome (CS) resulting from adrenocortical adenoma, and compared them with those in patients with primary aldosteronism (PA), renovascular hypertension (RVH) and essential hypertension (EH). In the CS group, each parameter, including serum potassium, plasma renin activity, plasma aldosterone, deoxycorticosterone and corticosterone concentrations, is within the normal range. However, plasma renin activity in the CS group was lower than that in the RVH group but higher than that in the PA group, and plasma aldosterone concentration was lower than that in each RVH or PA group. These findings indicated that the CS group had a different type of hypertension from that in either RVH or PA, in which the renin angiotensin system or mineralocorticoids play an important role in hypertension. Meanwhile, captopril (50 mg) administration either with or without indomethacin pretreatment decreased the mean blood pressure in the CS group, although captopril failed to change it in the PA group or in normal subjects. Furthermore, the pressor response to exogenous angiotensin II in the CS group was higher than that in the RVH or EH group, but was not different from that in the PA group. Thus, the hypertension in patients with CS due to adrenocortical adenoma appears to be mediated through a change in the renin-angiotensin system in the form of exaggerated pressor responses to angiotensin II.

1. Removal of the renal artery constriction but not of the clipped kidney restored the blood pressure to normal levels in Goldblatt two-kidney rats with hypertension of more than 4 months' duration. 2. Despite the differences in blood pressure response, both surgical procedures lowered plasma renin concentration to normal or below normal values. 3. Administration of the oral converting enzyme inhibitor SQ 14 225 produced a marked fall in blood pressure in Goldblatt kidney rats with chronic hypertension. However, a prolonged infusion of the angiotensin II antagonist saralasin was quite ineffective. The difference in response to the two inhibitors may have been due to bradykinin potentiation by the converting enzyme inhibitor. 4. Although plasma renin is often elevated in Goldblatt two-kidney rats with hypertension of more than 4 months' duration, the renin-angiotensin system plays no role in the maintenance of blood pressure at this stage.
