Background: Primary aldosteronism is a common cause of arterial hypertension, but its underlying molecular mechanisms are unknown. K+ is a key regulator of aldosterone secretion: it interacts with physiological secretagogues of aldosterone as angiotensin II (Ang II) end endothelin-1. In vivo genetic manipulation of a widely distributed class of channels, which generate background or ‘leak’ potassium (K+) currents, the twik-related acid-se...

The screening for primary aldosteronism (PA) is based on the aldosterone/renin ratio (ARR), which is calculated with the plasma renin activity (PRA) as denominator. A direct measurement of active renin (DRA) is being used as an alternative to PRA, but its diagnostic performance remains uncertain.Aim of the study was to head-to-head compare the ARR based on PRA (ARR-P) to on DRA (ARR-D), at baseline and post-captopril, for identifying aldosterone-producin...
