【 摘 要 】

References(21)Short-term intensive insulin therapy is effective for type 2 diabetes because it offers the potential to achieve excellent glycemic control and improve β-cell function.We observed that the time to glycemic goal (TGG) was adjustable.Original data of 138 newly diagnosed type 2 diabetic patients received intensive insulin therapy by continuous subcutaneous insulin infusion for 2-3 weeks were retrospectively collected.Subjects underwent an intravenous glucose tolerance test (IVGTT) and an oral glucose tolerance test (OGTT) pre and post treatment.The glycemic goal was achieved within 6 (4-8) days.Patients were divided into two groups by TGG above (TGG-slow) and below (TGG-fast) the median value.Patients in both groups had significantly better glycemic control.Compared with TGG-fast, TGG-slow required a few more total insulin and performed more improvement of HOMA-β and IVGTT-AUCIns, but less improvement of HOMA-IR and QUICKI.Multiple linear regression analysis revealed that TGG was always an explanatory variable for the changes (HOMA-β, IVGTT-AUCIns, HOMA-IR and QUICKI).The hypoglycemia prevalence was lower in TGG-slow (1.48% vs. 3.40%, P<0.01).Multivariate logistic regression analysis indicated that individuals in TGG-slow had a lower risk of hypoglycemia (adjusted OR, 0.700; 95% CI, 0.567-0.864; P<0.05).Multiple linear regression analysis confirmed that the ratio of the incremental insulin to glucose responses over the first 30 min during OGTT (ΔIns30/ΔG30), average insulin dose before achieving targets, initial insulin dose and LDL-c were independent predictors for TGG.It is intriguing to hypothesize that patients with fast time to glycemic goal benefit more in improving insulin sensitivity, but patients with slow time benefit more in improving β-cell function and reducing the risk of hypoglycemia.
