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.
On one hand, mutations on the gene NR3C2 (coding the mineralocorticoid receptor) cause the synthesis of a non-functional receptor which is unable to bind aldosterone or function correctly. In the kidney, aldosterone plays an important role of regulating sodium and potassium homeostasis by its actions on distal nephron cells.
Treatment for Addison's disease involves replacing the missing cortisol, sometimes in the form of hydrocortisone tablets, or prednisone tablets in a dosing regimen that mimics the physiological concentrations of cortisol. Alternatively, one-quarter as much prednisolone may be used for equal glucocorticoid effect as hydrocortisone. Treatment is ...
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 ...
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]
Androgen deprivation therapy (ADT), also called androgen ablation therapy or androgen suppression therapy, is an antihormone therapy whose main use is in treating prostate cancer. Prostate cancer cells usually require androgen hormones, such as testosterone, to grow.
Aldosterone production is also affected to one extent or another by nervous control which integrates the inverse of carotid artery pressure, pain, posture, and probably emotion (anxiety, fear, and hostility)(including surgical stress). The role of baroreceptors: Pressure in the carotid artery decreases aldosterone. The role of the ...
Alternatively, one could differentiate between the two syndromes by administering a potassium-sparing diuretic. Patients with Liddle's syndrome will only respond to a diuretic that binds the ENaC channel, whereas those with AME will respond to a diuretic that binds to ENaC or the mineralcorticoid receptor.
