Periodic ACTH discharge.
A 9 1/2-year-old girl is presented who had cyclical attacks of abdominal pain, vomiting, emotional disturbance, and marked weight change for two years. Associated findings were facial plethora, hypertension, transient hyperglycemia and glycosuria, elevated plasma ACTH, cortisol, and urinary 17-OHCS excretion, and low plasma osmolality with hyponatremia. Urinary excretion of catecholamines and porphyrin metabolites was not increased. Between episodes, she showed no abnormal clinical signs or laboratory data. The attacks were effectively suppressed with the administration of chlorpromazine. The disorder appears to be due to the periodic release of excessive ACTH; the cause remains unknown.
