Increased excretion of 18-hydroxycorticosterone in patients with adrenal adenomas and hypertension.

Abstract
Two female patients, 54 and 34 years old, each presented with an adrenal adenoma and hypertension. Blood pressure fell after removal of the tumors. The first patient had high urinary 18-hydroxycorticosterone and periodically elevated 18-hydroxy-deoxycorticosterone excretions. The second patient had elevated 18-hydroxycorticosterone and free cortisol excretions. Urinary aldosterone, aldosterone metabolites and plasma aldosterone were not increased. Plasma renin activity was suppressed and serum potassium levels were normal. After surgery, no elevated steroid values were found. Elevated 18-hydroxycorticosterone excretion may be an indicator of yet unknown hypertensinogenic mechanisms. The role of 18-hydroxycorticosterone in the etiology of hypertension is still unknown.
