Mineralocorticoids in congenital adrenal hyperplasia
1San Francisco General Hospital Medical Center, CA 94110.
Abstract:
While hypertension is observed in only two of the three major subtypes of congenital adrenal hyperplasia (CAH), 11 beta- and 17 alpha-hydroxylase deficiencies, deoxycorticosterone (DOC) production is increased in all. The elevated zona fasciculata (ZF) DOC produces mineralocorticoid hypertension with suppressed renin and reduced potassium concentrations. The DOC levels in 21-hydroxylase deficiency are in part produced by renin stimulation of the Zona glomerulosa (ZG) along with aldosterone. Assessment of the mineralocorticoid hormones of the ZF and ZF (17-deoxy steroids) provides additional unique characteristics of each subtype. Dissociation of DOC from cortisol is not unique to CAH. This dissociation is seen in other disorders and contrived conditions. There is a strong suggestion of a non-ACTH regulator of 17-deoxy steroids (DOC) that may contribute significantly to DOC production in general and effect DOC levels in CAH.

Hormonal Regulation
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
