Effect of short term intensive multitherapy on carotid intima-media thickness in patients with newly diagnosed type 2 diabetes mellitus / 中华医学杂志(英文版)

ABSTRACT

<p><b>BACKGROUND</b>Controlling plasma glucose levels, blood pressure and lipid levels is proven to reduce the risk of vascular complications in patients with type 2 diabetes mellitus. This has prompted intensive multitherapy targeted at several macrovascular risk factors. Carotid intima-media thickness (cIMT) is a reliable measure of early atherosclerosis. We sought to determine whether a 6-month intensive mutiltherapy program resulted in better goal attainment than usual care and its effect on the development of cIMT among patients with newly diagnosed type 2 diabetes mellitus.</p><p><b>METHODS</b>The study randomly assigned 220 patients with newly diagnosed type 2 diabetes mellitus to intensive or traditional therapy groups. The clinical parameters, such as fasting plasma glucose, total cholesterol, triglyceride, blood pressure, body weight and insulin were assessed at the baseline and after the 6-month therapy. cIMT of the patients was also obtained.</p><p><b>RESULTS</b>The average levels of fasting plasma glucose, hemoglobin A1c, total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) in the intensive group were significantly lower than those in the control group at the end of 6-month treatment. By 6 months, a higher proportion of patients in the intensive therapy group than in the control group attained goals for fasting plasma glucose (FPG), TC, LDL-C and hemoglobin A1c. With intensive multherapy the level of carotid intima-media thickness in the intensive therapy group was lower than that in the control group ((0.88 +/- 0.26) mm vs (0.96 +/- 0.22) mm, P < 0.01).</p><p><b>CONCLUSIONS</b>The evidence from this clinical trial demonstrates that intensive glucose, lipid and blood pressure control in patients with newly diagnosed type 2 diabetes is associated with diabetic macrovascular benefits. Intensive multitherapy allows more patients to achieve aims of control and may reduce macrovascular complications and delay disease progression.</p>
