title: ACTH secretion during sleep in a patient with Nelson's syndrome.
abstract: Plasma ACTH determinations were made by radioimmunoassay, every 10 min for 8 hours during sleep in a patient with Nelson's syndrome. The plasma ACTH concentrations were relatively stable, fluctuating in a narrow range. It is strongly suggested that the pituitary tumor itself was secreting ACTH in an autonomous manner and it is concluded that a neuronally initiated program of ACTH secretion, was absent in the present patient with Nelson's syndrome.
