Hypoaldosteronism causes low sodium (hyponatremia), high potassium (hyperkalemia), and metabolic acidosis, a condition in which the body produces excess acid. These conditions are responsible for the symptoms of hypoaldosteronism, which include muscle weakness, nausea, palpitations, irregular heartbeat, and abnormal blood pressure. [2]
Hypoaldosteronism is a clinical condition marked by either an aldosterone deficiency or impaired tissue-level action of the hormone. Angiotensin I to Angiotensin II conversion, adrenal aldosterone synthesis and secretion, abnormal target tissue response to aldosterone, and renal renin production and secretion are all potential causes of the ...
Specific treatment of pseudohyperaldosteronism depends on the inciting cause. General management focuses on countering the effects of excess mineralocorticoid activity to achieve adequate blood pressure control and avoid end-organ damage and cardiovascular mortality. [1] In some cases, specific antihypertensive medications may be recommended.
Pseudohypoaldosteronism (PHA) is a condition that mimics hypoaldosteronism (presenting hyperkalemia). [1] Two major types of primary pseudohypoaldosteronism are recognized and these have major differences in etiology and presentation. [2]
The genes encoding aldosterone synthase and 11β-hydroxylase are 95% identical and are close together on chromosome 8.In individuals with GRA, there is unequal crossing over so that the 5' regulatory region of the 11-hydroxylase gene is fused to the coding region of the aldosterone synthase.
Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [4] [5] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [6]
The endodermis is the innermost layer of cortex in land plants. It is a cylinder of compact living cells, the radial walls of which are impregnated with hydrophobic substances (Casparian strip) to restrict apoplastic flow of water to the inside. [1] The endodermis is the boundary between the cortex and the stele.
