Arms Assigned Interventions
Experimental: insulin lispro injection, exenatide injection Drug: insulin lispro injection, exenatide injection
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
Active Comparator: insulin lispro injection Drug: insulin lispro injection
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.

Detailed Description:

The UK Prospective Diabetes Study has shown that β-cell function progressively deteriorates over time in people with type 2 diabetes mellitus, irrespective of lifestyle and existing pharmacological interventions. The progressive nature of type 2 diabetes is one of the major challenges in the treatment of affected patients, and agents that could alter the natural history of this condition would add greatly to current treatment approaches. Short-term intensive insulin therapy of newly diagnosed type 2 diabetes will improve beta-cell function and usually leading to a temporary remission time. The effect of GLP-1 receptor agonists on beta-cells is stimulation of glucose-dependent insulin release, followed by enhancement of insulin biosynthesis. It is stimulating beta-cell proliferation, induction of islet neogenesis, and inhibition of ß-cell apoptosis. Exenatide is synthetic exendin-4, GLP-1 receptor agonist. Exenatide exerts direct effects on β-cell, which indicates that may contribute to delay disease progression. However, no study has evaluated effect of short-term intensive insulin sequential exenatide therapy model on β-cell function and glycemic remission rate in newly diagnosed type 2 diabetic patients. This current study is thus designed to evaluate effect of short-term intensive insulin sequential exenatide therapy model on β-cell function , glycemic control and glycemic remission rate in newly diagnosed type 2 diabetic patients.
