Autosomal recessive
What’s the pathophysiology in congenital adrenal hyperplasia?
Enzyme deficiency leads to decreased cortisol production leads to increased ACTH leading to adrenal hyperplasia
21 hydroxylase deficiency
Salt wasting, simple virilizing or nonclassical
Characterized by elevated 17-hydroxyprogesterone
11-beta hydroxylase deficiency
Increased accumulation of mineralocorticoids leading to HTN
17 alpha hydroxylase deficiency
Hypertension
Hypokalemia
Males are feminized
How do you prevent virilization in congenital adrenal hyperplasia?
Treat mom with dexamethasone starting at 4-5 weeks gestation then perform CVS and stop meds if karyotype is XY or if genotype not affected
What commonly causes nonclassical Congenital adrenal hyperplasia?
Usually due to 21-hydroxylase deficiency
What are the most common signs of nonclassical CAH?
Hirsutism, acne, oligomenorrhea
