Overview

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency must be differentiated from 11-β hydroxylase deficiency, 17-α hydroxylase deficiency, androgen insensitivity syndrome, polycystic ovarian syndrome, and adrenal tumor.

Differentiating congenital adrenal hyperplasia due to 21-hydroxylase deficiency from other diseases

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency classic type must be differentiated from diseases that cause ambiguous genitalia:[1][2]

Disease name Steroid status Other laboratory Important clinical findings
Classic type of 21-hydroxylase deficiency Increased:
  • 17-OHP
  • Progesterone
  • Androstenedione
  • DHEA

Decreased:

  • Aldosterone
  • Corticosterone (salt-wasting)
  • Cortisol (simple virilizing)
  • Low testosterone levels
  • Ambigus genitalia in female
  • Virilization in female
  • Salt-wasting
  • Hypotension and hyperkalemia
11-β hydroxylase deficiency Increased:
  • DOC
  • 11-Deoxy-cortisol
  • 17-hydroxy-progestrone, mild elevation

Decreased:

  • Cortisol
  • Corticosterone
  • Aldosterone
Low testosterone levels
  • Hypertension and hypokalemia
17-α hydroxylase deficiency Increased:
  • DOC
  • Corticosterone
  • Progesterone

Decreased:

  • Cortisol
  • Aldosterone
Low testosterone levels
3β-Hydroxysteroid Dehydrogenase Increased:
  • DHEA
  • 17-OH pregneno-lone
  • Pregnenolone

Decreased:

  • Cortisol
  • Aldosterone
  • Low testosterone levels
  • vomiting, volume depletion, hyponatremia, and hyperkalemia
  • 46-XY infants often show undervirilization, due to a block in testosterone synthesis
Gestational hyperandrogenism
  • Variable levels, depends on the cause of disease
  • Maternal serum androgen concentrations (usually testosterone and androstenedione) are high
  • If virilization is caused by exogenous hormone administration, the values may be low because the offending hormone is usually a synthetic steroid not measured in assays for testosterone or other androgens
  • Androgen excess sign and symptoms in mother
  • History of androgen containing medication consumption during pregnancy in mother
  • Virilization in a 46,XX individual with normal female internal anatomy
  • Causes include maternal luteoma or theca-lutein cysts, and placental aromatase enzyme deficiency

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency Non-classic type must be differentiated from diseases that cause virilization and hirsutism in female:[3][2][4]

Disease name Steroid status Other laboratory Important clinical findings
Non-classic type of 21-hydroxylase deficiency Increased:
  • 17-OHP
  • Exaggerated androstene-dione, DHEA, and 17-OHP

response to ACTH

Low testosterone levels
11-β hydroxylase deficiency Increased:
  • DOC
  • 11-Deoxy-
  • cortisol

Decreased:

  • Cortisol
  • Corticosterone
  • Aldosterone
Low testosterone levels
17-α hydroxylase deficiency Increased:
  • DOC
  • Corticosterone
  • Progesterone

Decreased:

  • Cortisol
  • Aldosterone
Low testosterone levels
3β-Hydroxysteroid Dehydrogenase Increased:
  • DHEA
  • 17-OH pregneno-lone
  • Pregnenolone

Decreased:

  • Cortisol
  • Aldosterone
Low testosterone levels
  • Salt-wasting adrenal crises in infancy
  • Mild virilization of genetically female infants
  • Undervirilization of genetically male infants, making it the only form of CAH which can cause ambiguous genitalia in both genetic sexes.
Polycystic ovary syndrome
  • High DHEAS and androstenedione levels
  • Low testosterone levels
  • Polycystic ovaries in sonography
  • Obesity
  • PCOS is the most common cause of hirsutism in women
  • No evidence another diagnosis
Adrenal tumors
  • Variable levels depends on tumor type
  • Low testosterone level
  • Older age
  • Rapidly progressive symptoms
Ovarian virilizing tumor
  • Variable levels depends on tumor type
  • Testosterone is high
  • Older age
  • Rapidly progressive symptoms
Cushing's syndrome.
  • Increase cortisol & metabolites
  • Variable other steroids
  • Variable mineralocorticoid excess
  • Cushingoid features
hyperprolactinemia
  • Normal levels of most of steroids
  • Increased prolactin
  • Infertility, galactorrea
