Effect of a somatostatin analog on insulin requirement and hormone levels in 6 insulin-dependent juvenile-onset diabetics subjected to artificial pancreas.Acta Diabetol Lat. 1980 Jan-Mar; 17(1):9-14.AD
This study was performed in order to investigate the effect of a 12-h infusion of the somatostatin selective analog D-Trp8, D-Cys14 Serono, (SRIF-A), on insuli requirement and C-peptide (CP), growth hormone (GH) and glucagon (IRG) levels in 6 insulin-dependent diabetics submitted to 60-h artificial pancreas (Biostator Miles) metabolic control from 2000 of the first day to 0800 of the fourth day. Meals were given at 1200 and 1700 of the second and third day. Before meals and 1-2 h after meals, plasma levels of CP, GH and IRG were measured. The two 12-h periods (midday-midnight) with and without continuous SRIF-A 12-h infusion (40 microgram/h) were considered. The SRIF-A infusion caused a 20% reduction in insulin requirement (p < 0.05) and a slight but significant reduction of GH levels (p < 0.05). CP and IRG were unaffected.
