The purpose of this study was to determine the effect of adjuvant premeal pramlintide with postmeal insulin on postprandial hyperglycemia in children with type 1 diabetes mellitus (T1DM).
Eight adolescents with T1DM on intensive insulin therapy participated in an open-label, non-randomized, crossover study, comparing postprandial glucose excursions in study A (prescribed insulin regimen and given premeal) vs. study B (pramlintide + insulin). Prandial insulin dose for study B was decreased by 20% and given postmeal, while pramlintide was given just before the meal. Blood glucose (BG), glucagon, and pramlintide concentrations were measured basally and at timed intervals during a 300-min study period.
Postprandial incremental BG for the duration of the study was reduced in study B vs. study A with AUC((-60 to 300 min)) (area under the curve) at 6600 +/- 2371 vs. 20 230 +/- 3126 mg/dL/min (367 +/- 132 vs. 1124 +/- 174 mmol/L/min) (p < 0.001). Glucagon concentration was suppressed for approximately 120 min following administration of 30 microg of pramlintide and postmeal insulin (p < 0.003). No severe hypoglycemic episodes were experienced in this study.
Postprandial hyperglycemia is considerably reduced in adolescents with T1DM when treated with fixed-dose premeal pramlintide, and precisely calculated postmeal insulin, without significant side effects.
本研究旨在确定辅助餐前使用普兰林肽联合餐后使用胰岛素对1型糖尿病(T1DM)患儿餐后高血糖的影响。
8名接受强化胰岛素治疗的T1DM青少年参与了一项开放标签、非随机、交叉研究,比较研究A(规定的胰岛素治疗方案并在餐前给药)与研究B(普兰林肽+胰岛素)的餐后血糖波动情况。研究B的餐时胰岛素剂量减少20%并在餐后给药,而普兰林肽在餐前给药。在300分钟的研究期间,基础状态以及定时测量血糖(BG)、胰高血糖素和普兰林肽浓度。
与研究A相比,研究B在研究期间餐后BG增量降低,曲线下面积(AUC(-60至300分钟))为6600±2371 vs. 20230±3126mg/dL/分钟(367±132 vs. 1124±174mmol/L/分钟)(p<0.001)。给予30μg普兰林肽和餐后胰岛素后,胰高血糖素浓度被抑制约120分钟(p<0.003)。本研究中未发生严重低血糖事件。
对于T1DM青少年,采用固定剂量的餐前普兰林肽和精确计算的餐后胰岛素治疗时,餐后高血糖可显著降低,且无明显副作用。
