This page contains general information about Hyperaldosteronism. For more information on specific types, please visit the pages on Primary hyperaldosteronism, and Secondary hyperaldosteronism.

Synonyms and keywords: Aldosteronism

Classification

Aldosteronism and mineralocorticoid excess may be classified into two types, primary hyperaldosteronism (conn's syndrome) and secondary hyperaldosteronism. Below table discusses the different types of aldosteronism.

Primary hyperaldosteronism or Conn's syndrome
Syndrome of apparent mineralocorticoid excess [AME]
Chronic licorice ingestion
Hypersecretion of nonaldosterone mineralocorticoids
Adrenal carcinoma
Ectopic ACTH
Renin secreting tumors
Renal artery stenosis

Differentiating Diagnosis

Hyperaldosteronism should be differentiated from other diseases causing hypertension and hypokalemia for example:

• Renal artery stenosis
• Cushing's syndrome
• Congenital adrenal hyperplasia (CAH)
  • 17 alpha hydroxylase deficiency
  • 11 beta hydroxylase deficiency
• Liddle's syndrome
• Diuretic use
• Licorice ingestion
• Renin-secreting tumors

Hypertension and Hypokalemia

Plasma renin activity

Normal or High (Plasma Renin/Aldosterone ratio <10

Suppressed (Plasma Renin/Aldosterone ratio >20

*Renin-secreting tumors *Diuretic use *Renovascular hypertension *Coarctation of aorta *Malignant phase hypertension

Urinary aldosterone

Elevated

Normal

Low

Conn's syndrome (Primary aldosteronism)

Profound K+ depletion

• 17 alpha hydroxylase deficiency • 11 beta hydroxylase deficiency • Liddle's syndrome • Licorice ingestion • Deoxycortisone producing tumor

Add Mineralocrticoid antagonist for 8 weeks

BP response

No BP response

• Deoxycorticosterone excess( Tumor, 17 alpha hydroxylase and 11 beta hydroxylase deficiency) • Licorice ingestion •Glucocorticoid resistance

Liddle's syndrome)
