==Overview==
The mainstay of therapy for congenital adrenal hyperplasia due to 21-hydroxylase deficiency is [[glucocorticoid]] replacement.
Medical therapy for classic type of 21-hydroxylase deficiency includes maternal administration of [[dexamethasone]] for [[genetically]] diagnosed intranatal patients. [[Hydrocortisone]] and [[fludrocortisone]] is given in children and [[Adult|adults]]. Treatment for non-classic type of 21 hydroxylase deficiency in children includes [[hydrocortisone]] up to [[puberty]] and in women in reproductive age, [[oral contraceptive pills]] are given for regulation of [[menstrual cycle]]. Men with non-classic type of 21 hydroxylase deficiency are [[asymptomatic]] and do not need any treatment.

==Early-onset: Severe 21-hydroxylase deficient congenital adrenal hyperplasia==
=== 1. Prenatal treatment===
====Salt-wasting crisis in infancy====
In the [[prenatal]] period [[virilization]] of female [[fetus]] begins early; therefore, early treatment is required as follows:
*[[Hydrocortisone]] and intravenous [[saline]] and [[dextrose]] are the mainstay treatment of adrenal crisis.
* If classic [[CYP21A2]] [[gene]] [[mutations]] exist in parents, [[maternal]] administration of [[dexamethasone]] should be prescribed.
*This treatment quickly restores [[blood volume]], [[blood pressure]], and body sodium content, and reverses the [[hyperkalemia]].
** Preferred regimen: [[Dexamethasone]] 20 micrograms/kg q24h in 2 or 3 fractioned doses [[Orally ingested|orally]].
*With appropriate treatment, most infants are out of danger within 24 hours.<ref name="Wikipeadia"> https://en.wikipedia.org/wiki/Congenital_adrenal_hyperplasia_due_to_21-hydroxylase_deficiency</ref>
*** [[Dexamethasone]] crosses the [[placenta]] into the [[fetal circulation]] and prevents [[ambiguous genitalia]] in female [[fetus]].
*** This treatment should be started before 9 weeks of [[pregnancy]] age; if treatment cannot be started by 9 weeks, it should not be given at all.
*** If [[Cell-free system|cell-free]] [[fetal]] [[DNA testing]] reveals the gender to be male, treatment should be discontinued.
*** Approximately 85% of managed cases appear quite normal after [[delivery]].
*** [[Side effects]] of [[prenatal]] [[dexamethasone]] are:<ref name="pmid208234662">{{cite journal| author=Speiser PW, Azziz R, Baskin LS, Ghizzoni L, Hensle TW, Merke DP et al.| title=Congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency: an Endocrine Society clinical practice guideline. | journal=J Clin Endocrinol Metab | year= 2010 | volume= 95 | issue= 9 | pages= 4133-60 | pmid=20823466 | doi=10.1210/jc.2009-2631 | pmc=2936060 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=20823466  }}</ref><ref name="pmid9814461">{{cite journal| author=Lajic S, Wedell A, Bui TH, Ritzén EM, Holst M| title=Long-term somatic follow-up of prenatally treated children with congenital adrenal hyperplasia. | journal=J Clin Endocrinol Metab | year= 1998 | volume= 83 | issue= 11 | pages= 3872-80 | pmid=9814461 | doi=10.1210/jcem.83.11.5233 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=9814461  }}</ref><ref name="pmid18060943">{{cite journal| author=Carmichael SL, Shaw GM, Ma C, Werler MM, Rasmussen SA, Lammer EJ et al.| title=Maternal corticosteroid use and orofacial clefts. | journal=Am J Obstet Gynecol | year= 2007 | volume= 197 | issue= 6 | pages= 585.e1-7; discussion 683-4, e1-7 | pmid=18060943 | doi=10.1016/j.ajog.2007.05.046 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=18060943  }}</ref><ref name="pmid27482827">{{cite journal| author=Wallensteen L, Zimmermann M, Thomsen Sandberg M, Gezelius A, Nordenström A, Hirvikoski T et al.| title=Sex-Dimorphic Effects of Prenatal Treatment With Dexamethasone. | journal=J Clin Endocrinol Metab | year= 2016 | volume= 101 | issue= 10 | pages= 3838-3846 | pmid=27482827 | doi=10.1210/jc.2016-1543 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=27482827  }}</ref><ref name="pmid24278432">{{cite journal| author=Khalife N, Glover V, Taanila A, Ebeling H, Järvelin MR, Rodriguez A| title=Prenatal glucocorticoid treatment and later mental health in children and adolescents. | journal=PLoS One | year= 2013 | volume= 8 | issue= 11 | pages= e81394 | pmid=24278432 | doi=10.1371/journal.pone.0081394 | pmc=3838350 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24278432  }}</ref>

====Long-term management of congenital adrenal hyperplasia====
=== 2. Neonatal treatment ===
Management of infants and children with congenital adrenal hyperplasia is complex and warrants long term care in a [[pediatric endocrinology|pediatric endocrine clinic]]. After the diagnosis is confirmed, and any salt-wasting crisis averted or reversed, major management issues include:
'''2.1 Medical therapy for 21-hydroxylase deficiency in the neonates is as follows:'''<ref name="pmid20823466">{{cite journal| author=Speiser PW, Azziz R, Baskin LS, Ghizzoni L, Hensle TW, Merke DP et al.| title=Congenital adrenal hyperplasia due to steroid 21-hydroxylase deficiency: an Endocrine Society clinical practice guideline. | journal=J Clin Endocrinol Metab | year= 2010 | volume= 95 | issue= 9 | pages= 4133-60 | pmid=20823466 | doi=10.1210/jc.2009-2631 | pmc=2936060 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=20823466  }}</ref>
*Initiating and monitoring hormone replacement
* Preferred regimen: [[Hydrocortisone]] 20 to 30 mg/m<sup>2</sup>  q24h divided in three doses [[Orally ingested|PO]] '''<u>AND</u>''' [[Fludrocortisone]] 100 mcg q12h [[Orally ingested|PO]] '''<u>AND</u>''' [[sodium chloride]] one gram or 4 mEq/kg q24h divided in several doses [[Orally ingested|PO.]]
*Stress coverage, crisis prevention, parental education
** The minimization of [[steroid]] doses should be considered to avoid [[steroid]] [[complications]] in [[infants|infants.]] 
*Reconstructive surgery
** Growth suppression and shorter height in adulthood are the [[complications]] of using high dose [[steroids]] which occurs in [[neonates]].
*Optimizing growth
'''2.2 Ambiguous genitalia:''' 
*Optimizing androgen suppression and fertility in women with congenital adrenal hyperplasia
* [[Ambiguous genitalia]] should be managed immediately. 
=====Hormone replacement=====
* [[Infants]] with [[ambiguous genitalia]] and non palpable [[gonads]] should be considered to have [[congenital adrenal hyperplasia]] and [[empirical treatment]] should be start early after obtaining [[blood]] sample for [[17-hydroxyprogesterone]].
* Initial [[empiric therapy]] should contains doses of [[glucocorticoid]] and [[mineralocorticoid]] and [[sodium chloride]] supplementation.
** Preferred regimen: [[Hydrocortisone]] is 20 to 30 mg/m<sup>2</sup> q24h divided in three doses [[Orally ingested|PO]] '''<u>AND</u>''' [[Fludrocortisone]] 100 mcg q12h [[Orally ingested|PO]] '''<u>AND</u>''' [[sodium chloride]] one gram or 4 mEq/kg q24h divided in several doses [[Route of administration|PO]].  
'''2.3 Adrenal crisis:'''
* Preferred regimen: [[Normal saline]] 0.9 percent, 20 mL/kg [[intravenous]] [[Bolus (medicine)|bolus]] '''<u>AND</u>''' [[dextrose]] 10 percent 2 to 4 mL/kg [[intravenous]] [[Bolus (medicine)|bolus]] (if there is significant [[hypoglycemia]]) '''<u>AND</u>''' [[hydrocortisone]] 50 to 100 mg/m<sup>2</sup> [[intravenous]] [[Bolus (medicine)|bolus]], '''<u>THEN</u>''' continue [[hydrocortisone]] alone 50 to 100 mg/m<sup>2</sup> [[Intravenous therapy|IV]] per day divided into four times per 24 hours.
** The [[blood]] sample should be obtained for [[steroid hormone]] levels before giving [[hydrocortisone]].  
** [[Hyperkalemia]] should be corrected on the base of its level and [[complications]].


*[[Glucocorticoid]]s provide a reliable substitute for [[cortisol]] and reduce [[ACTH]] level, reducing ACTH also reduces the stimulus for continued hyperplasia and overproduction of androgens in both sexes.
===3. Management in children===
:*[[Hydrocortisone]] or liquid [[prednisolone]] is preferred in infancy and childhood.
* Preferred regimen: [[Hydrocortisone]] ([[cortisol]]) in a dose of 10 to 15 mg/m<sup>2</sup> [[body surface area]]/day [[Orally ingested|PO]] '''<u>AND</u>''' [[fludrocortisone]] in a dose of 50 to 200 mcg per day (0.05 to 0.20 mg/day) [[Orally ingested|PO]].
:*[[Prednisone]] or [[dexamethasone]] are often more convenient for adults.
** [[Mineralocorticoid]] replacement should be started in all 21-hydroxylase deficient patients, and often may be tapered after six months of age.  
:*Dose is typically started at the low end of physiologic replacement (6-12 mg/m<sup>2</sup>) but is adjusted throughout childhood to prevent both growth suppression from too much and androgen escape from too little glucocorticoid.
'''3.1 Response to therapy can be monitored by checking the following parameters:'''
:*Serum levels of [[17-hydroxyprogesterone|17OHP]], [[testosterone]], [[androstenedione]], and other adrenal steroids are followed for additional information, but may not be entirely normalized even with optimal treatment.
* Serum [[17-hydroxyprogesterone]]
* [[Androstenedione]]
* [[Plasma renin activity]] or direct [[renin]]
* Height measurements


*[[Mineralocorticoid]]s are replaced in all infants with salt-wasting and in most patients with elevated [[renin]] levels.
===4. Management in adults===
:*[[Fludrocortisone]] is the only pharmaceutically available mineralocorticoid, doses of (0.05 to 2 mg) daily is recommended.

=====Optimizing growth in congenital adrenal hyperplasia=====
'''4.1 Treatment goals'''
*[[Glucocorticoids]] are essential for health and dosing is always a matter of approximation. In even mildly excessive dose, glucocorticoids can slow growth.
* Provide proper dosing of [[glucocorticoid]] and [[mineralocorticoid]].
*Adrenal androgens are readily converted to [[estradiol]], which accelerates [[bone age|bone maturation]] and can lead to early epiphyseal closure.
* Decrease secretion of [[cosyntropin]]; therefore decrease [[adrenal]] overstimulation and [[androgen]] production.
*Rate of growth is assessed by checking the [[bone age]] every year or two through periodic measurement of [[17OHP]] and [[testosterone]] levels.
'''4.2 Glucocorticoids and mineralocorticoid replacement''' 
*[[Gonadotropin-releasing hormone]] agonists such as [[leuprolide]] are used to slow bone maturation and suppress precocious puberty.
* Preferred regimen: [[Hydrocortisone]] 15-30 mg q24h divided into three doses [[Orally ingested|PO]] '''<u>AND</u>''' [[Fludrocortisone Acetate|9-alpha-fludrocortisone acetate]] 0.1 to 0.2 mg q24h [[Orally ingested|PO]].
*[[Antiandrogen]] such as [[flutamide]] reduce the conversion of testosterone to estradiol.
* Alternative regimen (1): [[Dexamethasone]] 0.75 mg q24h [[Orally ingested|PO]] '''<u>AND</u>''' [[Fludrocortisone Acetate|9-alpha-fludrocortisone acetate]] 0.1 to 0.2 mg q24h [[Route of administration|PO]].
*[[Aromatase inhibitor]] such as [[testolactone]] also block conversion of testosterone to estradiol.
* Alternative regimen (2): [[Prednisone]] 5mg q24h [[Orally ingested|PO]] '''<u>AND</u>''' [[Fludrocortisone Acetate|9-alpha-fludrocortisone acetate]] 0.1 to 0.2 mg q24h [[Orally ingested|PO]].
*[[Bilateral adrenalectomy]] rarely used to remove the androgen sources.
'''4.3 Considerations'''
*[[Growth hormone treatment]] is used to enhance growth.<ref name="Wikipeadia"> https://en.wikipedia.org/wiki/Congenital_adrenal_hyperplasia_due_to_21-hydroxylase_deficiency</ref><ref name="pmid11344936">{{cite journal| author=Migeon CJ, Wisniewski AB| title=Congenital adrenal hyperplasia owing to 21-hydroxylase deficiency.

*[[Glucocorticoids]] reduce the excess production of [[adrenal]] [[androgens]] and reduce the excessive secretion of both [[corticotropin-releasing hormone]] and [[ACTH]].
* Stress dosing: In patients with 21-hydroxylase deficiency and serious [[illness]], [[glucocorticoids]] stress dosing is necessary.
* [[Dexamethasone]] is very potent and long-acting [[glucocorticoid]] that effectively suppresses [[ACTH]] secretion but almost always causes the development of [[cushingoid appearance]] with chronic use.
* The proper dose of [[Fludrocortisone Acetate|fludrocortisone acetate]] should be used to restore normal [[serum]] [[potassium]] concentrations and [[plasma renin activity]].
'''4.4 Therapy consideration in women'''
* Lowering blood [[androgen]] levels with [[glucocorticoids]], can helps women to control annoying [[Cosmetics|cosmetic]] [[symptoms]] such as [[acne]] and [[hirsutism]].
* In  21-hydroxylase deficient patients [[oral contraceptive pills]] in combination with [[glucocorticoids]] can be used to regulate the [[menstrual cycle]] and induction of [[ovulation]].

Overview

Medical therapy for classic type of 21-hydroxylase deficiency includes maternal administration of dexamethasone for genetically diagnosed intranatal patients. Hydrocortisone and fludrocortisone is given in children and adults. Treatment for non-classic type of 21 hydroxylase deficiency in children includes hydrocortisone up to puberty and in women in reproductive age, oral contraceptive pills are given for regulation of menstrual cycle. Men with non-classic type of 21 hydroxylase deficiency are asymptomatic and do not need any treatment.

Medical Therapy for classic type of 21 hydroxylase deficiency

Medical therapy for 21-hydroxylase deficiency in prenatal period, neonates, children and adults, is as below:[1][2][3][4][5]

1. Prenatal treatment

In the prenatal period virilization of female fetus begins early; therefore, early treatment is required as follows:

2. Neonatal treatment

2.1 Medical therapy for 21-hydroxylase deficiency in the neonates is as follows:[4]

2.2 Ambiguous genitalia: 

2.3 Adrenal crisis:

3. Management in children
