Luteinizing hormone-releasing hormone and serum growth hormone in insulin-dependent diabetes.

Growth hormone (GH) responses were studied in 26 insulin-dependent diabetics after the intravenous administration of 100 microgram of synthetic luteinizing hormone-releasing hormone (LH-RH). Although the mean basal GH concentration was significantly higher than that of 20 matched non-diabetic controls, no significant increment occurred after the LH-RH injection. (The controls also showed no rise in GH.) It seems that the GH hypersecretion of insulin-requiring diabetics does not, as is frequently noted in acromegaly, respond to the injection of LH-RH.
