Normoreninemic hypoaldosteronism in a case of isolated ACTH deficiency.

Abstract

This paper documents the rare and hitherto unreported association between isolated ACTH deficiency and normoreninemic hypoaldosteronism in a 63-year-old woman. Baseline plasma aldosterone and 18-hydroxycorticosterone were extremely low. Both steroids did not respond to exogenous angiotensin II infusion, whereas they were increased in parallel to ACTH stimulation. Thus, acquired dysfunction or congenital dysgenesis of the zona glomerulosa was suspected. The upright posture-furosemide test showed a subnormal but definite plasma aldosterone response coupled with a normal increase in plasma renin activity, indicating that there may be a yet unidentified mechanism(s) underlying the postural increase of aldosterone.
