No inhibition of corticotrophin (ACTH)-hypersecretion in adrenal insufficiency by somatostatin.

Somatostatin (250 micrograms as a bolus iv and 250 micrograms as a 1 h infusion) was administered to 6 patients with primary adrenal insufficiency (Addison's disease). The fall in plasma ACTH during the infusion period ranged between 0-30% with a mean reduction of 11.2 +/- 11.6%. These findings suggest that with the method employed, somatostatin is not an inhibitor of ACTH secretion in a condition in which glucocorticoids are lacking.

Probable pituitary adenoma with adrenocorticotropin hypersecretion (corticotropinoma) secondary to Addison's disease.

A 50-yr-old woman with Addison's disease from the age of 14 yr was diagnosed as empty sella turcica in 1974 (Rev Clin Esp 139: 183, 1975). She subsequently continued with hyperpigmentation in spite of adequate hormone substitution therapy which permitted her to lead a normal life. When studied she showed an extreme elevation of plasma ACTH (1500--2000 pg/ml), and with dexamethasone (2 and 8 mg/day) continued to have levels of 900 pg/ml. With 60 mg hydrocortisone daily, effects of overdosage were observed (swelling and Cushingoid facies) associated with depigmentation. However, she continued to manifest levels of plasma ACTH of 700 pg/ml and an absence of circadian rhythm. It seems likely that this patient represents a case of pituitary ACTH secretory adenoma (corticotropinoma) secondary to the preexisting Addison's disease. The circulating levels of other pituitary hormones were normal.
