Aldosterone is a steroid hormone produced by the adrenal cortex in the adrenal gland, is the most potent mineralocorticoid in humans, it regulate sodium and potassium balance in the blood. Aldosterone secretion appears to be stimulated primarily through the renin-angiotensin system. Acting on mineralocorticoid receptors (MR) on principal cells in the collecting ducts of the kidneys, it increases the permeability of their apical (luminal) membrane to potassium and sodium and activates their basolateral Na+/K+ pumps, stimulating ATP hydrolysis, reabsorbing sodium (Na+) ions and water into the blood, and excreting potassium (K+) ions into the urine. Aldosterone regulate plasma bicarbonate (HCO3-) levels and its acid/base balance. Aldosterone is responsible for the reabsorption of about 2% of filtered sodium in the kidneys. Plasma aldosterone levels normally vary with body position (upright>supine) and salt intake. Overall plasma aldosterone levels show a circadian rhythm which is similar to but less marked than cortisol, with peak levels in the early morning; about 75% of the daily production is secreted between 04:00 am and 10:00 am each day. Age-related levels tend to decline from fetal through adult life. Abnormally high plasma aldosterone concentrations can occur in adenomas, glucocorticoid-responsive hyperaldosteronism, idiopathic. Abnormally low aldosterone secretion occurs in a number of conditions including salt-wasting forms of congenital adrenal hyperplasia, nephropathy, and renal tubular acidosis.
