Clinical Trial: Study of Prevalence and Clinical Phenotype in Patients With Glucocorticoid-Remediable Aldosteronism

Study Status: Completed
Recruit Status: Completed
Study Type: Observational

Official Title:

Brief Summary:

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.

Detailed 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.
