Overview
Medical Therapy
Neonatal management
Prenatal treatment
In the prenatal period virilization of female fetus begins early; therefore, early diagnosis and treatment are required as following :
- If classic CYP21A2 gene mutations exist in parents, maternal administration of dexamethasone should be applied. Dexamethasone crosses the placenta into the fetal circulation and prevents ambiguous genitalia in female fetus.
- This treatment should be started before nine weeks of pregnancy age; if treatment cannot be started by 9 weeks, it should not be given at all.
- If in cell-free fetal DNA testing male fetus detected, treatment should be discontinued.[1]
- Approximately 85% of managed cases appear quite normal after delivery.[2]
- Side effects of prenatal dexamethasone are:[3][4][5][6][7]
- Postnatal failure to thrive
- Psychomotor developmental delay
- Increased risk of cleft lip and palate
- Increased risk for psychiatric disturbances and ADHD
Neonatal treatment
- Hydrocortisone is 20 to 30 mg/m2/day divided in three doses
- Fludrocortisone 100 mcg twice daily
- One gram or 4 mEq/kg/day of sodium chloride divided in several doses
- One first time high doses of hydrocortisone, 50 mg/m2/day, can be used in order to suppress adrenal hormones.
- The minimization of steroid doses should be considered to avoid steroid complications in infants.
- Growth suppression and shorter height in adulthood are the complications of using high dose steroids which occurs in neonates.
Ambiguous genitalia
- Ambiguous genitalia should be managed immediately. 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
- Reconstructive surgery can be done in patients.
Adrenal crisis
- Normal saline 0.9 percent, 20 mL/kg should be administered.
- An intravenous bolus of 2 to 4 mL/kg of 10 percent dextrose should be considered if there is significant hypoglycemia.
- Initial dose of hydrocortisone of 50 to 100 mg/m2 should be administered as an IV bolus, then 50 to 100 mg/m2 IV per day divided four times a day.
- 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.
Children management
- Hydrocortisone (cortisol) in a dose of 10 to 15 mg/m2 body surface area/day orally
- Mineralocorticoid replacement should be started in all children and often may be tapered after six months of age.
- Response to therapy can be monitored by below items:
- Serum 17-hydroxyprogesterone
- Androstenedione
- Plasma renin activity or direct renin
- Height measurements
Adults management
- Treatment goals are:
- Provide proper dosing of glucocorticoid and mineralocorticoid, and decrease secretion of cosyntropin.
Glucocorticoids
- Glucocorticoids reduce the excess production of adrenal androgens and reduce the excessive secretion of both corticotropin-releasing hormone and ACTH.
- Preferred Regimen
- Hydrocortisone 15-30 mg/d divided into three doses
- Alternative Regimen:
- Dexamethasone a very potent and long-acting glucocorticoid effectively suppresses ACTH secretion but almost always causes the development of cushingoid appearance with chronic use.[8]
- Combination therapy, with typical doses of hydrocortisone to replace the cortisol deficiency during the day and a very small dose of a long-acting glucocorticoid. We suggest this approach when standard hydrocortisone regimens are ineffective.
- Stress dosing: patients with classic 21hydroxyalase deficiency should be provided stress dosing.[9]
Mineralocorticoid replacement
- Fludrocortisone acetate, in a dose sufficient to restore normal serum potassium concentrations and plasma renin activity.[10]
- The usual adult dose of fludrocortisone is 0.1 to 0.2 mg/day.[11]
- Patients who are undertreated and in chronic poor control develop testicular adrenal rest tumors.
Infertility in men
- Sperm production is often impaired in untreated men due to defected spermatogenesis and leydig cells suppression.[12]
- Most of the patients have severe oligospermia. Moreover, Most of the untreated patients have testicular tumors that need surgical removal.
- An elevated FSH is a sensitive indicator for patients fertility condition but semen analysis is the specific test.[13]
Infertility in women
- Lowering blood androgen levels helps women to control annoying cosmetic symptoms such as acne and hirsutism.
- Similar to polycystic ovary syndrome, 21 hydroxylase deficiency patients need oral contraceptive pills to regulate the menstrual cycle and induction of ovulation.[14]
- Women need pregnancy should consult a surgeon to repair previous genital malformations.
- Hydrocortisone doesn’t pass placenta so, it can be used safely during pregnancy.
- Glucocorticoids doses need to increase at end of pregnancy with careful monitoring.
