Alterations in sodium reabsorption in collecting duct epithelium can have severe implications for the normal function of the nephron and may precipitate the development of secondary hypertension. One of the principal protein kinases involved in sodium transport in the nephron is the serum and glucocorticoid regulated kinase (SGK1) that mediates translocation and insertion of the epithelial sodium channel (ENaC) into the plasma membrane. SGK1 appears to be increased in the kidn...

Background: Screening for primary aldosteronism (PA) using the aldosterone to renin ratio (ARR) is recommended by clinical practice guidelines in patient groups with a high prevalence as the disease is reported by several authors in more than 10% of essential hypertensives (EH).Methods: Plasma aldosterone concentration (PAC) and direct renin (DR) were measured using two novel automated chemiluminescence assays (IDS-iSYS; Boldon, UK) and compared to the S...
