title: [Dynamics of growth hormone secretion in patients with primary hypothyroidism, before and after treatment with thyroideal hormones].
abstract: Growth hormone (GH) secretion was studied in a group of alut controls and a series of patients with primary hypothyroidism before and after treatment with thyroid hormones. Intravenous insulin-induced hypoglycemia was the stimulus used (0,1 UI/kg body weight). It is concluded that in primary hypothyroidism, GH secretion is almost absent due to relative inactivity of the somatotropic cells and/or lack of GH-RH. This decreased secretory response becomes rapidly normal after treatment with physiological doses of thyroid hormones.
