It is well known that Long-term hyperglycemia (also known as glucose toxicity) contribute to impairment in islet β-cell function and development of insulin resistance. A growing body of evidence also indicates that this impairment inβ-cell function and insulin action could be restored after hyperglycemia is corrected by short-term intensive insulin therapy. In this study, we are determined to use the golden standard of insulin sensitivity evaluation in vivo—hyperinsulinemia euglycemic glucose clamp—to estimate insulin resistance improvement in patients before and after intensive insulin therapy, investigate first phase insulin secretion to evaluate β-cell function, examine the changes in insulin resistance and insulin secretion resulting from normalization of plasma glucose levels in both lean and obese patients by insulin pump therapy.

Further study details as provided by China-Japan Friendship Hospital:

Primary Outcome Measures:
  • AUC75-120 of Glucose Infusion Rate (GIR) [ Time Frame: after 2 weeks insulin pump intensive therapy, and one-year follow-up after termination of treatments ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • AUC0-10 of Acute Insulin Response (AIR) during IVGTT [ Time Frame: after 2 weeks insulin pump intensive therapy, and one-year follow-up after termination of treatments ] [ Designated as safety issue: No ]

Estimated Enrollment: 130
Study Start Date: October 2008
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: insulin aspart
    Insulin Aspart will be administrated by insulin pump with an initial dose of 0.4-0.6u/kg body weight, of which 50% basal rate and the other 50% bolus dose. Time interval for administration will be as follows: 0-3Am-9Am-12Am-5Pm-9Pm-0Am. Specific adjustment will be made according to individual difference.
