Effect of Short-Term Intensive Insulin Sequential Exenatide Therapy in Newly Diagnosed Type 2 Diabetic Patients

First, Patients in the exenatide group will receive short-term continuous subcutaneous insulin (CSII)therapy. The doses will be titrated every day in order to attain the glycaemic goal which is defined as a fasting capillary blood glucose of less than 6.1 mmol/L and capillary blood glucose at 2 h after each of three meals of less than 8.0 mmol/L. Treatments will be maintained for 2 weeks after the glycaemic target will be reached. Then, patients will Sequential be treated with 5 mcg bid for 4 weeks and then 10 mcg bid for 8 weeks. After interventions will be stopped, patients will be instructed to continue diet and physical exercise only and will be followed-up with glycaemic monitoring monthly

Patients in the control group will receive insulin with an insulin pump. The doses will be titrated every day in order to attain the glycaemic goal. Treatments will be maintained for 2 weeks after the glycaemic target will be reached. Then interventions will be stop, patients will be instructed to continue diet and physical exercise only and will be followed-up with glycaemic monitoring monthly.
