Adrenogenital Syndrome

Adrenogenital Syndrome – Treatment Options

Introduction
Adrenogenital syndrome, also known as congenital adrenal hyperplasia (CAH), is a group of autosomal recessive disorders caused by enzyme deficiencies in adrenal steroid biosynthesis, most commonly 21-hydroxylase deficiency. The impaired cortisol synthesis leads to excessive ACTH stimulation, resulting in adrenal hyperplasia and overproduction of adrenal androgens. Clinical manifestations depend on the enzyme defect and severity, ranging from salt-wasting crisis in neonates to virilization, precocious puberty, infertility, or menstrual irregularities in later life. Treatment aims to restore hormonal balance, prevent adrenal crisis, and manage androgen excess.

1. Glucocorticoid Replacement

• Hydrocortisone is the mainstay in children to replace deficient cortisol and suppress excess ACTH.

  • Dose: 10–15 mg/m²/day orally, divided into 2–3 doses.

• In adults, prednisolone or dexamethasone may be used for better ACTH suppression.

• Overtreatment must be avoided, as it can lead to iatrogenic Cushing’s syndrome, growth suppression in children, and metabolic complications.

2. Mineralocorticoid Replacement (in Salt-Wasting Forms)

• Fludrocortisone acetate is given to correct aldosterone deficiency.

  • Dose: 0.05–0.2 mg/day orally.

• Sodium chloride supplementation is often required in infants (1–2 g/day).

• Regular monitoring of electrolytes, blood pressure, and plasma renin activity guides dose adjustments.

3. Management of Androgen Excess

• Glucocorticoid therapy reduces ACTH-driven androgen overproduction.

• In females:

  • May improve menstrual regularity and fertility.

  • Cosmetic and surgical interventions (clitoroplasty, vaginoplasty) may be considered in severe virilization.

• In males:

  • Therapy prevents precocious puberty and testicular adrenal rest tumors.

4. Treatment of Acute Adrenal Crisis

• Hydrocortisone 100 mg IV bolus, followed by 200 mg/24 h infusion or divided doses.

• IV normal saline with dextrose to correct hypovolemia, hyponatremia, and hypoglycemia.

• Transition to oral maintenance therapy after stabilization.

5. Fertility and Reproductive Management

• Women may require assisted reproductive technologies if fertility remains impaired despite hormonal therapy.

• Men with testicular adrenal rest tumors may need intensified glucocorticoid therapy or surgery if tumors are large and symptomatic.

6. Surgical Considerations in Virilized Females

• Genital reconstructive surgery may be performed in childhood or adolescence depending on severity and cultural/ethical considerations.

• Long-term multidisciplinary follow-up is essential for physical and psychological outcomes.

---

7. Long-Term Monitoring and Supportive Care

• Regular assessment of growth, puberty progression, bone age, fertility, and metabolic health.

• Monitoring of 17-hydroxyprogesterone, androstenedione, renin, and electrolytes to guide therapy.

• Psychological support and counseling to address body image, sexual health, and fertility concerns.

8. Patient and Family Education

• Families should be trained in stress dosing of steroids during illness, surgery, or trauma.

• Patients must carry a medical alert bracelet and emergency hydrocortisone injection kit.

• Genetic counseling is recommended for families with a history of CAH.
