RESUMO
This study was aimed to observe if the lipid profiles, apoprotein B100 (ApoB100), ApoAI, high density lipoprotein (HDL) and its subclasses could be improved by controlling the blood glucose. Fifty-three patients with newly diagnosed type 2 diabetic were divided into four groups, diet and exercise group (n = 13), continuous subcutaneous insulin infusion (CSII) group (n = 14), multiple daily insulin injection group (MDI, n = 13), and oral hypoglycaemic agents group (n = 13). Fasting blood glucose (FPG), glycated hemoglobin A1c (HbA1c), lipid profiles, ApoB100, ApoAI and HDL subclasses were measured at beginning and a month later. Forty-three patients finished the testing. The levels of FPG, HbA1c, triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and ApoB100 were decreased significantly (P < 0.05) in all groups, and ApoAI/ApoB100 increased obviously (P < 0.05). Comparatively matured HDL subclasses such as HDL2b were increased (P < 0.05), and comparatively infantile HDL subclasses such as HDL3b were decreased (P < 0.05). Therapy with hyperglycemic agents improved TG, TC, LDL-C, ApoB100, ApoAI/ApoB100, and HDL2b significantly (P < 0.05), but intervention with the diet and exercise group alone did not improve lipid profiles, apolipoproteins, and HDL subclasses (P > 0.05). Meanwhile, therapy with insulin intensive therapy (MDI, CSII) group had the most powerful effect on decreasing ApoB100 concentration (P < 0.05). The results suggested that lipid profiles, apolipoproteins, and quantity and quality of HDL subclasses might be improved by blood glucose controlling.
