Abstract
The effect of octreotide on morning hyperglycemia and GH levels was evaluated in eight insulin-dependent diabetic patients. Octreotide (50 mcg) was administered through subcutaneous injections at different hours (20: 00, 22: 00 and 24: 00h) or through continuous subcutaneous night infusion from midnight to 08: 00 at increasing rate between 03: 00 and 08: 00h. After octreotide injection at midnight we noticed a sharp decrease of both glycemia (p<0.005) and GH (p<0.05) at 04: 00h, but not at 08: 00h. Only the night continuous infusion at increasing rate was able to reduce glycemia and GH at 04: 00 and at 08: 00h (p<0.001 and p<0.01 respectively). The injections of octreotide at 20: 00 and 22: 00h lowered GH values at 24: 00h (p<0.01 and p<0.05 vs insulin alone) but did not show any signicant effect on blood glucose levels and GH at 04: 00 and 08: 00h. In conclusion, only the continuous subcutaneous night infusion of octreotide at increasing rate during the last hours of the night was able to reduce simultaneously morning hyperglycemia and GH levels in insulin-dependent diabetic patients, whereas evening subcutaneous injections at different times did not show any appreciable effect.
