Objectives: Insulin resistance is one of strong predictions on the remission in patients with newly diagnosed type 2 diabetes (T2DM) after short-term insulin intensive therapy (SIIT). Therefore, the purpose of this study is to explore if the short-term change of insulin resistance can predict the long-time remission.
Methods: This study enrolled 160 patients with newly diagnosed type 2 diabetes mellitus (103 male, aged 49.8±10.4 yrs,HbA1c11±2.1%). All of them have been treated by 2-week continuous subcutaneous insulin infusion as SIIT when new diagnosed. HOMA-IR was compared just at the termination of SIIT and later then follow up every 3 months regularly for 5 years.
Results: After short-term intensive treatment, up to 84.4%, 81.3% and 26.9% of patients achieved disease remission with T2DM at the termination of CSII, the 3rd month and 5th year follow up without use of medication. The average remission time were 27+/-615 months. The average changes of HOMA-IR in the first 3 months after SIIT were 30%+/-52%. This short-term change percent of HOMA-IR was positive related to the statue of remission at 5th-year follow-up (r = 0.778, p <0.0001). The ROC curve analysis showed below.
Conclusions: Maintaining the improving insulin resistance after short-term insulin intensive therapy is essential for the long-time remission from T2DM. Lifestyle interventions might be helpful.
