Abstract. The recovery of the hypothalamo-pituitary-adrenal axis after selective transsphenoidal adenomectomy was studied in 3 patients with Cushing's disease by measuring basal plasma ACTH and cortisol concentrations, cortisol secretion rate, the diurnal rhythm of cortisol, and the reaction of cortisol to lysine vasopressin (LVP), of compound S to metyrapone and of cortisol and growth hormone to an insulin-induced hypoglycaemia. The third patient had been treated previously by external pituitary irradiation. In 2 patients basal plasma ACTH levels returned within normal values before plasma cortisol, but no supra-physiological plasma concentrations of ACTH were seen as has been observed after withdrawal of exogenous glucocorticoids. With regard to the different stimulation tests: at first the normal reaction of plasma cortisol to LVP returned after 3 months, at the same time as the restoration of growth hormone secretion in response to hypoglycaemia. A normalization of the reaction to metyrapone was seen thereafter while finally the reaction of cortisol to an insulin-induced hypoglycaemia and the diurnal rhythm of plasma cortisol returned 15 to 18 months after operation in the first patient and after 12 months in the second patient. Selective adenomectomy had also been carried out in the third patient, as evidenced by normal TSH, LH and FSH secretion. Hypocortisolism, and a deficient ACTH and growth hormone secretion in response to the stimuli mentioned, however, did not normalize up till 22 months after operation. The restoration of the hypothalamo-pituitary-adrenal axis after selective pituitary adenomectomy in Cushing's disease was prevented in this patient by prior external pituitary irradiation.

Adrenal Response

SUMMARY The plasma sugar, 11-hydroxycorticosteroid, and growth hormone responses to insulin have been studied in patients with Cushing's disease. They showed an impaired or absent plasma 11-hydroxycorticosteroid and growth hormone rise during the test, as compared with control subjects, despite the injection of amounts of insulin which produced a similar degree of hypoglycaemia. This test proved of value in differentiating between these patients and those with 'simple ' obesity since the latter usually showed a normal growth hormone and adrenal response provided an adequate amount of insulin was administered. The patients with Cushing's disease also had an impaired adrenal response to pyrogen and to dexamethasone administration and failed to show a normal plasma 11-hydroxycorticosteroid circadian rhythm. Their response to corticotrophin, lysine vasopressin, and metyrapone, however, was normal or enhanced. It is suggested that these findings imply an abnormality of hypothalamic or cerebral control and not a primary defect of pituitary function as proposed originally by Harvey Cushing. The growth hormone response to insulin remained impaired in four out of six patients totally adrenalectomized for Cushing's disease but was normal in three patients adrenalectomized for other reasons. It is suggested that the defect which impairs the adrenal response to insulin may, on occasions, also impair the mechanism normally operative for growth hormone secretion.

Observation Period

The function of the growth hormone-releasing hormone (GHRH)-growth hormone (GH) axis in Cushing's disease was studied by monitoring (a) the GH responses to GHRH loading and L-dopa loading, (b) the GHRH response to L-dopa loading, and (c) the daytime profiles of plasma GH concentration. GH release following GHRH and L-dopa was blunted in patients as compared to that in age-matched control subjects. However, GHRH release following L-dopa was similar in patients and controls. The plasma GH levels in four patients measured every 20 min by a highly sensitive immunoradiometric assay for GH showed pulsatile GH secretion at low levels during the observation period. These results indicate that GHRH release from the hypothalamus is preserved in patients with Cushing's disease, and support the hypothesis that glucocorticoid inhibits GH secretion by altering the hypothalamic somatostatin tone.
