Abstract:
Objective Hyperglycemic clamp technique (HGCT) was performed to evaluate the effect of short-term intensive insulin therapy on the first and second-phase (1PH and 2PH) insulin secretion and maximum insulin secretion (MIS) in newly diagnosed type 2 diabetics. Methods Twelve volunteers with normal glucose tolerance (NC group) and six newly diagnosed type 2 diabetics (DM group) were included and HGCT was performed to assess the function of pancreatic islet beta cell. Then HGCT was repeated in the 6 patients following two week intensive insulin therapy. Results The levels of secreted insulin in 1PH, 2PH and MIS were 257?36 mU/L, 63?5 mU/L and 80?5 mU/L in NC group respectively, and 95?19 mU/L, 34?9 mU/L and 39?12 mU/L in DM group respectively. 1PH insulin secretion was significantly improved in the diabetics following 2 week treatment compared with that before the treatment (135?27 mU/L vs 95?19 mU/L, P=0.01). The insulin secretions in 2PH and MIS were slightly increased (40?9 mU/L vs 34?9 mU/L, P=0.09, 46?11 mU/L vs 39?12 mU/L,P=0.08, respectively). Conclusions Short-term intensive insulin therapy can improve the insulin secretions significantly in 1PH and slightly in 2PH and MIS in newly diagnosed type 2 diabetics.
