Adrenal steroids such as glucocorticoids and mineralocorticoids are commonly used as treatments in diseases such as Congenital adrenal hyperplasia. [2] CAH commonly causes overproduction of androgens, glucocorticoid treatment is used to reduce Adrenocorticotropic hormone (ACTH) and reduce the production of androgens allowing for symptoms of CAH to be managed though treatment is required to be ...
If CAH is caused by the deficiency of the 21-hydroxylase enzyme, then treatment aims to normalize levels of androstenedione, but normalization of 17α-hydroxyprogesterone is a sign of overtreatment. [32] Treatment can be monitored by measuring androstenedione and 17α-hydroxyprogesterone levels in blood or saliva. [32]
[4] [6] [8] While AG inhibits all of the enzymes listed above, inhibition of P450scc is primarily responsible for its inhibition of adrenal steroidogenesis. [25] In terms of adrenal androgens, AG has been shown to significantly suppress dehydroepiandrosterone sulfate, androstenedione, testosterone, and dihydrotestosterone levels in men. [6]
The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis. [2]
Androstenedione is created from dehydroepiandrosterone (DHEA) or 17-hydroxyprogesterone. [ 10 ] A deficiency in the HSD17B3 gene is characterized biochemically by decreased levels of testosterone which results in the insufficient formation of dihydrotestosterone during fetal development.
Serum levels of 17OHP, testosterone, androstenedione, and other adrenal steroids are followed for additional information, but may not be entirely normalized even with optimal treatment. As regular monitoring is needed, patients can be monitored non-invasively by measuring 17OHP and androstenedione in saliva. [ 211 ] (
17β-Hydroxysteroid dehydrogenases (17β-HSD, HSD17B) (EC 1.1.1.51), also 17-ketosteroid reductases (17-KSR), are a group of alcohol oxidoreductases which catalyze the reduction of 17-ketosteroids and the dehydrogenation of 17β-hydroxysteroids in steroidogenesis and steroid metabolism.
3β-Hydroxysteroid dehydrogenase/Δ 5-4 isomerase (3β-HSD) (EC 1.1.1.145) is an enzyme that catalyzes the biosynthesis of the steroid progesterone from pregnenolone, 17α-hydroxyprogesterone from 17α-hydroxypregnenolone, and androstenedione from dehydroepiandrosterone (DHEA) in the adrenal gland.
