N2 - Context: The purpose of this study was to examine the effect of continuous sc replacement of amylin and insulin for a 24-h period on glucose homeostasis in adolescents with type 1diabetes. Methods: Thirteen adolescents with type 1 diabetes on insulin pump therapy participated in a randomized, controlled, crossover design study comparing continuous sc insulin monotherapy (part A) vs. continuous sc insulin and pramlintide infusion (part B). In part A, basal and bolus insulin infusion was per prescribed home regimen. In part B, the basal insulin infusion was the same as part A, but prandial insulin boluses were reduced by 20%. Basal and prandial bolus pramlintide were administered simultaneously via another pump. All boluses were given as a dual wave. Results: The study regimen resulted in a 26% reduction in postprandial hyperglycemia as compared to insulin monotherapy (area under the curve, 600 min, 2610 ± 539 vs. 692 ± 861 mg/liter·min) (P < 0.008). Glucagon concentrations were suppressed postprandially (P < 0.003) but not in the postabsorptive state, whereas plasma insulin concentrations were unchanged. Conclusions: Simultaneous continuous sc pramlintide and insulin infusion has the potential of improving glucose concentrations by way of physiological replacement.
