Neonatal salt loss in the hypertensive form of congenital adrenal hyperplasia. 1980

J H Holcombe, and B S Keenan, and B L Nichols, and R T Kirkland, and G W Clayton

The 11 beta-hydroxylase deficiency (11OHD) form of congenital adrenal hyperplasia is diagnosed infrequently during the newborn period. A child presumed to have the 21-hydroxylase deficiency form of congenital adrenal hyperplasia was studied extensively as an infant. The diagnosis was based on ambiguous genitalia, elevated 17-ketosteroids, evidence of urinary 11-ketopregnanetriol, and salt loss. Severe hypertension was detected at 11 years, and 11 beta-hydroxylase deficiency was confirmed with elevated plasma 11-deoxycorticosterone and 11-deoxycortisol, low cortisol, and normalization of blood pressure following glucocorticoid replacement. Impaired aldosterone biosynthesis and salt loss were demonstrated during dexamethasone therapy. Salt loss during infancy does not distinguish between the 11 beta- and 21-hydroxylase deficiency forms of congenital adrenal hyperplasia.

D000312 Adrenal Hyperplasia, Congenital A group of inherited disorders of the ADRENAL GLANDS, caused by enzyme defects in the synthesis of cortisol (HYDROCORTISONE) and/or ALDOSTERONE leading to accumulation of precursors for ANDROGENS. Depending on the hormone imbalance, congenital adrenal hyperplasia can be classified as salt-wasting, hypertensive, virilizing, or feminizing. Defects in STEROID 21-HYDROXYLASE; STEROID 11-BETA-HYDROXYLASE; STEROID 17-ALPHA-HYDROXYLASE; 3-beta-hydroxysteroid dehydrogenase (3-HYDROXYSTEROID DEHYDROGENASES); TESTOSTERONE 5-ALPHA-REDUCTASE; or steroidogenic acute regulatory protein; among others, underlie these disorders.
