Practical Pearls

The Spironolactone Test

Liddle's syndrome is resistant to mineralocorticoid receptor antagonists like Spironolactone because the defect is in the ENaC channel itself, not the receptor. If HTN and hypokalaemia persist on high-dose Spironolactone but respond to Amiloride, Liddle's is highly likely.

Other Mimics

Apparent Mineralocorticoid Excess (AME) and licorice ingestion mimic Liddle's because they involve saturation of the 11β-HSD2 enzyme, allowing cortisol to activate the mineralocorticoid receptor. Both result in suppressed renin and suppressed aldosterone.
