Siblings of 21-hydroxylase deficiency (non-salt-losing) with aldosterone hypersecretion. Glucocorticoid replacement therapy remains of central importance in the adult with 21-OHD, despite the disturbing fact that many patients will discontinue or neglect their treatment for months at a time. PubMed Central Linear growth ceases, and reproductive function becomes an issue. in the early 1950s [3], these children have been able to survive into adulthood. Nebesio TD, Eugster EA: Observation of hypertension in children with 21-hydroxylase deficiency: a preliminary report. Most patients manage to take 2 doses a day consistently, patterned after doses used for adrenal insufficiency, such as 1520mg on arising and 510mg after the midday meal. Consequently, the adult adrenal of a patient with 21-OHD makes large amounts of a few steroids, mainly progesterone (P4), 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone and its sulfate (DHEA[S]), plus lesser amounts of androstenedione (AD), testosterone (T) [7], and 21-deoxycortisolwhich has little glucocorticoid or mineralocorticoid activity.

In women with 21-OHD, two additional key issues are: (1) whether androgen excess symptoms are currently a problem, and (2) if the patient trying to conceive a child now. Conversely, greater accumulation of P4 can contribute to anovulation and infertility in women with 21-OHD. 10.1056/NEJMra021561. Reduced bone mineral density has been found in 21-OHD in most studies [35, 36], but the degree is moderate, and frank osteoporosis is uncommon. 1950, 86: 249-, CAS All subsequent discussion will be limited to 21-OHD. In children, several groups have found empirically that administration of the largest dose at bedtime is associated with tightest control of adrenal steroidogenesis.

Consequently, the focus and goals of treatment are quite different in adults and children. Cytochrome P450c21 (CYP21A2) deficiency precludes aldosterone and cortisol synthesis, limiting steroidogenesis to the reactions catalyzed by 3-hydroxysteroid dehydrogenase type 2 (3-HSD2), cytochrome P450c17 (CYP17A1), and a bit to cytochrome P450c11 (CYP11B1) (Figure 1(a)). 
At a minimum, all women with 21-OHD must receive replacement doses of hydrocortisone and fludrocortisone acetate, as would any other patient with adrenal insufficiency. 2022 BioMed Central Ltd unless otherwise stated. Correspondence to Clinical Endocrinology. The .gov means its official. Spironolactone, an effective and inexpensive agent used to treat other forms of hirsutism and PCOS, is difficult to use in 21-OHD because it is both androgen and mineralocorticoid receptor antagonist, which causes salt loss.

Unfortunately, well-designed and controlled studies comparing various regimens are lacking, so the clinician is advised to generally try the safest and most physiologic replacement regimen, and then to intensify therapy gradually if symptoms and signs of undertreatment become evident. Sustained-release hydrocortisone preparations administered once daily with promising pharmacokinetics have been developed [32], but these products currently are not widely available. Due to zonation, two critical enzyme activities required for T synthesis are physically separated in the adrenal gland. An official website of the United States government.

Therapy is expected to change over time as the norm rather than the exception. This scenario is evidently the case for CAH. The most common cause of CAH is 21-hydroxylase deficiency (21-OHD) [1], which afflicts about 1:15,000 live births [2]. Google Scholar. A recent report demonstrated that 21/23 women with 21-OHD who desired pregnancy became pregnant and had live births using these regimens [46]. Journal of Clinical Endocrinology and Metabolism. Morimoto I, Yamamoto S, Tateishi H, Ueda S, Toda Y, Zeki K, Watanabe K, Nakano Y, Kashimura M, Eto S. Intern Med. For these reasons, not only the control of steroids exiting the adrenal, but also the extra-adrenal metabolism of these steroids is an important consideration in understanding the physiology of CAH in the adult. Low cortisol increases ACTH production, flooding the adrenal steroidogenic machinery with upstream precursors (Figure 1(b)). Pediatrics. The New England Journal of Medicine. Considerable genetic and biochemical evidence suggests that this route contributes to DHT formation and genital virilization in female fetuses with cytochrome P450-oxidoreductase deficiency, presumably due to the accumulation of 17-OHP [1518]. At a minimum, men with 21-OHD should have an annual testicular exam, and screening ultrasonography is recommend by some authorities. 10.1016/j.mce.2004.04.009. 10.1016/j.fertnstert.2007.03.051.

Treatment of CAH in infancy and early childhood strives first to prevent salt-wasting and hypotensive crises due to adrenal insufficiency. 10.1677/JOE-08-0337. Women should receive cervical smears, breast exams, and/or mammograms at the standard ages, and men require screening for prostate disease. Men with CAH of experience few symptoms from reducing or stopping therapy, until they become seriously ill or their testicular rests become uncomfortably large. In addition, women with 21-OHD often develop a secondary polycystic ovary syndrome (PCOS), such that androgens and 17-OHP also derive from the ovaries and persists even after adrenal suppression [40]. Since the introduction of cortisone therapy by Wilkins et al. 2020 Jun 14;123(11):1312-1320. doi: 10.1017/S0007114520000173. Am J Med. 10.1074/jbc.272.25.15959. The extent and routes of peripheral metabolism vary considerably amongst individuals and might explain to some degree the differences in disease control for adults with 21-OHD. Nutrients.

CAS Men with 21-OHD are spared the disturbing and disfiguring effect of contrasexual hormone excess, which probably renders men with 21-OHD more prone to neglect their treatment than women. Ogilvie CM, Rumsby G, Kurzawinski T, Conway GS: Outcome of bilateral adrenalectomy in congenital adrenal hyperplasia: one unit's experience. Google Scholar. In addition to controlling androgen excess, follicular phase progesterone should be suppressed below 2nmol/L (0.6ng/mL) to favor fertilization and implantation [46]. 2010, 95 (5): 2065-2072. Mineralocorticoid replacement with 9-fludrocortisone acetate, 0.050.2mg/d, is usually continued, with the goal of a suppressed or low-normal plasma renin activity, which blunts the hypovolemic drive to ACTH production. As discussed elsewhere, the congenital adrenal hyperplasias (CAHs) are genetic defects in cortisol biosynthesis.

Bethesda, MD 20894, Web Policies The trend now is to minimize surgery in the newborn and child and to leave complete establishment of an adequate vaginal orifice for when the woman becomes sexually active. If control has been poor in childhood, the patient seems to be more vulnerable to androgen excess, possibly due to greater adrenal hyperplasia.

Based on the above discussion, the adrenal glands of adults with 21-OHD produce little T and huge amounts of other steroids, yet none are active hormones except for P4. In addition to peripheral conversion of DHEA[S] to active androgens, P4, which accumulates 2 steps prior to the block, can be 21-hydroxylated by hepatic cytochromes P450 [27, 28] to yield 11-deoxycorticosterone (DOC), a potent mineralocorticoid. If the mass regresses, the treatment is continued for several weeks to months until a satisfactory result is obtained. The zona fasciculata cells, which contain 3-HSD2 activity, also contain CYP17A1; however, these cells have low 17,20-lyase activity because expression of the important cofactor protein cytochrome (b5) is low [8, 9]. 2003, 16 (5): 289-296.
