  • Hyperaldosteronism


OBJECTIVES: I. Determine the prevalence of glucocorticoid-remediable aldosteronism (GRA) in various hypertensive populations and screen at risk members of GRA pedigrees. II. Investigate other factors regulating blood pressure in GRA (environmental, genetically determined factors). III. Investigate renal and hormonal mechanisms regulating potassium homeostasis in GRA. IV. Describe clinical phenotype of GRA patients. V. Prospectively screen GRA-affected patients with MRI angiography for intracranial aneurysm.

Study summary:

PROTOCOL OUTLINE: Patients are screened for high blood pressure, suppressed plasma renin activity level, and low potassium levels. Urine is collected for a 24 hour period. Blood specimen is collected for molecular biologic evaluation for the presence of the chimeric gene diagnostic of GRA. Any history of cardiovascular events is recorded.


PROTOCOL ENTRY CRITERIA: --Disease Characteristics-- Diagnosed glucocorticoid-remediable aldosteronism (GRA) with hypertension Hypokalemia is variably seen Blood pressure variably elevated Elevated level of aldosterone Low level of plasma renin activity
