Glucocorticoid Remediable Aldosteronism in a Family with a Strong History of Cerebral Aneurysms and Hypertension.

Abstract

Glucocorticoid remediable aldosteronism (GRA) also known as familial hyperaldosteronism type 1 (FH1) is a rare genetic form of primary aldosteronism characterized by aldosterone overproduction regulated by adrenocorticotropic hormone (ACTH). We present the case of a 54-year-old woman with severe hypertension and hypokalemia. Genetic testing confirmed GRA by identifying a chimeric gene involving CYP11B1 and CYP11B2. This case highlights the importance of considering GRA in patients with resistant hypertension and a family history of cerebral aneurysms. Management involved glucocorticoid therapy and mineralocorticoid receptor antagonists, leading to significant improvement in blood pressure control.
