Hypoaldosteronism is an endocrinological disorder characterized by decreased levels of the hormone aldosterone. Similarly, isolated hypoaldosteronism is the condition of having lowered aldosterone without corresponding changes in cortisol . [ 1 ] (
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.
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 ...
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.
The two genes show 93% homology to each other and are both encoded on the same chromosome. [8] Research has shown that calcium ions activate transcription factors at CYP11B2 through well defined interactions at the 5'-flanking region of CYP11B2. [5] Aldosterone synthase is a member of the cytochrome P450 superfamily of enzymes. [9]
Congenital adrenal hyperplasia due to 11β-hydroxylase deficiency is a form of congenital adrenal hyperplasia (CAH) which produces a higher than normal amount of androgen, [1] resulting from a defect in the gene encoding the enzyme steroid 11β-hydroxylase (11β-OH) which mediates the final step of cortisol synthesis in the adrenal. 11β-OH CAH results in hypertension due to excessive ...
The treatment is a potassium-sparing diuretic, such as amiloride, that directly blocks the sodium channel. [8] Potassium-sparing diuretics that are effective for this purpose include amiloride and triamterene; spironolactone is not effective because it acts by regulating aldosterone and Liddle syndrome does not respond to this regulation.
