To determine whether adrenomedullary structure and endocrine function are impaired in patients with congenital adrenal hyperplasia caused by classic 21-hydroxylase deficiency.
Measured plasma and urinary catecholamines alongside plasma metanephrines in 38 children with congenital adrenal hyperplasia (25 salt-wasting, 13 simple virilizing), 39 age-matched normal controls, and 20 bilateral adrenalectomy patients.
Conducted histological and electron-microscopical examinations of adrenal specimens from 3 bilateral adrenalectomy patients and 8 autopsy cases with 21-hydroxylase deficiency.
Plasma epinephrine, plasma metanephrines, and urinary epinephrine excretion were 40 to 80 percent lower in patients with congenital adrenal hyperplasia than in normal subjects (P<0.05), with the lowest values in those with the most severe cortisol deficits.
Urinary epinephrine excretion and plasma epinephrine concentrations were at or below the assay detection limit in 21 percent (8/38) of congenital adrenal hyperplasia patients and 95 percent (19/20) of adrenalectomy patients, and were approximately 50 percent lower in patients previously hospitalized for adrenal crises.
Histological evaluations revealed incomplete adrenal medulla formation and chromaffin cells depleted of secretory vesicles in adrenalectomy specimens from congenital adrenal hyperplasia patients.
