The decreased secretion of renin caused by the negative feedback due to increased mineralocorticoid
levels is due to the increase in DOCA (1,2).
Aldosterone is a steroid hormone with strong mineralocorticoid
2+] is modestly effective, but drugs used to reduce renal electrolyte losses (amiloride, mineralocorticoid
receptor antagonists) are poorly tolerated, as they often exacerbate hypotension through enhancing natriuresis.
She also had low cortisol (and its precursors 17[alpha]-hydroxyprogesterone and 11-deoxycortisol), low adrenal androgens (DHEA sulfate and androstenedione), high mineralocorticoids
precursors (11-deoxycorticosterone and corticosterone), high ACTH, and chromosomal analysis revealed a normal male karyotype 46 XY.
The management of Addison's disease is focused mainly on the correction of hypovolaemia and electrolyte imbalances with adequate amounts of intravenous fluids, the correction of hypoglycaemia, long-term glucocorticoid and mineralocorticoid
replacement and the management of underlying causes.
These hormones are generally not affected by Addison's disease, which affects only those secreted by the adrenal cortex: glucocorticoid and mineralocorticoid
Despite optimized life-saving glucocorticoids and mineralocorticoids
replacement therapy, health-related quality of life in adrenal insufficiency is more severely impaired than previously thought12.
Since therapeutic steroids glucocorticoids are very similar chemically to mineralocorticoids
, their use in large quantities may also lead to metabolic alkalosis.
Pregnenolone is the source of multiple hormones, including a class of hormones called mineralocorticoids

The outer layer (cortex) of each adrenal gland secretes a number of hormones, including glucocorticoids, which regulate the metabolism of proteins, fats and carbohydrates; and mineralocorticoids
, which help maintain a proper balance of water, sodium and potassium in a cat's body.
