About
Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings. A dual-hormone closed-loop system would regulate glucose levels through the infusion of two hormone: insulin and glucagon.
The main objective of this project is to compare the efficacy of single-hormone closed-loop strategy, dual-hormone closed-loop strategy and pump therapy to regulate overnight glucose levels in a out-patient study in adults and adolescents with type 1 diabetes.
The investigators hypothesized that dual-hormone closed-loop strategy is more effective in regulating overnight glucose levels in adults and adolescents with type 1 diabetes compared to single-hormone closed-loop strategy, which in turn is more effective than the conventional pump therapy.

Closed-loop strategy is composed of three components: glucose sensor to read glucose levels, insulin pump to infuse insulin and a dosing mathematical algorithm to decide on the required insulin dosages based on the sensor's readings. A dual-hormone closed-loop system would regulate glucose levels through the infusion of two hormone: insulin and glucagon.
We aim to conduct a multicenter study to compare the efficacy of conventional pump therapy, single-hormone closed-loop strategy and dual-hormone closed-loop strategy to regulate overnight glucose levels, at home, in adolescents and adults with type 1 diabetes. Each intervention will be tested on two nights: 1) After a carbohydrate-rich dinner meal (to exaggerate hyperglycemic risk and; 2) After an evening exercise (to exaggerate hypoglycemic risk).
