Primary hyperaldosteronism, a common cause of secondary hypertension, requires specific diagnostic tests. Early detection and differentiation between aldosterone-producing adenoma and idiopathic hyperaldosteronism guide appropriate treatment strategies.
Area of Science:
- Endocrinology
- Cardiology
- Nephrology
Context:
- Primary hyperaldosteronism is the most frequent secondary cause of hypertension.
- Diagnosis is crucial in patients with hypokalemic or resistant hypertension, and adrenal incidentalomas.
- Screening involves measuring the plasma aldosterone (PAC) to plasma renin concentration (PRC) ratio.
Purpose:
- To outline diagnostic and differential diagnostic approaches for primary hyperaldosteronism.
- To differentiate between aldosterone-producing adenoma and idiopathic hyperaldosteronism.
- To guide therapeutic decisions based on the specific subtype of primary hyperaldosteronism.
Summary:
- Screening for primary hyperaldosteronism uses the PAC/PRC ratio, with considerations for medication and assay-specific cutoffs.
- Confirmatory tests include the saline infusion test or 24-h urinary aldosterone-18-glucuronide.
- Differential diagnosis employs imaging (CT/MRT), posture testing, and adrenal vein catheterization to distinguish between adenoma and idiopathic forms.
Impact:
- Accurate diagnosis and subtype differentiation are essential for effective management of primary hyperaldosteronism.
- Surgical intervention is indicated for aldosterone-producing adenoma.
- Medical management with spironolactone is the standard treatment for idiopathic hyperaldosteronism.

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
