ß-Cell dysfunction and decreased insulin sensitivity are the main pathophysiological defects responsible for the development of hyperglycemia. With continuous presence of insulin resistance, progressive loss of ß-cell function is the crucial defect. Hyperglycemia has deleterious effect on β-cell function, which is partially reversible by adequate glycemic control. In newly diagnosed type 2 diabetic patients with severe hyperglycemia, 2 weeks continuous subcutaneous insulin infusion (CSII) can induce adequate glycemic control with improvement of β-cell function. Nearly half of the patients can maintain euglycemia longer than 12 months by transient CSII. The improvement of β-cell function, especially the restoration of the first-phase insulin response is related to sustained euglycemia in the newly diagnosed type 2 diabetic patients. But it is unclear whether any other interventions (such as oral hypoglycemic agents and multiple daily injections) inducing optimal glycemic control in a short period of time can have the same effect. As a multicenter, open-label, randomized, parallel-group study will be needed to further prove and clarify the findings.
