Guyton. 13th edition. Page. 781Congenital Adrenal Hyperplasia Types21 β-Hydroxylase deficiencyAccounts for about 90 of the cases  75 of the cases have mineralocorticoid deficiency  Neonates may present with a salt-wasting crisis.  Salt wasters tend to have hyponatremia, hyperkalemia, and raised plasma renin.  17-hydroxyprogesterone is elevated.  Increased androgens lead to virilization of the female fetus and sexual ambiguity at birth  Males are phenotypically normal at birth but develop precocious pseu- do puberty, growth acceleration, premature epiphyseal plate closure, and diminished final height.  Goal in treatment is to bring glucocorticoid and mineralocorticoid back to the normal range which would also suppress adrenal androgen secretion.  Give hydrocortisone to act as feedback inhibition on pituitary11 β-Hydroxylase deficiency  Clinical features of increased androgens similar to the preceding form,  including virilization of female fetus.  The principal difference with this form is the hypertension produced by 11-deoxycorticosterone, along with hypokalemia and suppressed renin secretion.  Treatment for all forms of CAH is glucocorticoids such as hydrocortisone and dexamethasone.  17 α-Hydroxytlase deficiency  Extremely rare  Usually diagnosed at the time of puberty when the patient presents with hypertension, hypokalemia, and hypogonadism  Individuals have eunuchoid characteristics.
