Modulatory effect on dyslipidemia and anti-atherosclerotic function of in newly diagnosed type 2 diabetes

SUN Mingxiao, WANG Yao, CHI Jiamin

Frontiers of Medicine 2008, Volume 2, Issue 2,   Pages 174-177 doi: 10.1007/s11684-008-0032-z

Abstract: The modulatory effect of on dyslipidemia and the preventive effect on atherosclerosis in newly diagnosed type 2 diabetic patients were studied. A prospective clinical trial was conducted to test the effectiveness of in selected 201 newly diagnosed type 2 diabetic patients. All patients were randomly divided into two groups: 108 with therapy and 93 without therapy. The mean follow-up period was 22 months. The blood glucose and blood pressure of all patients were under control. Serum levels of total cholesterol (TC), triglyceride (TG), and low density lipoprotein cholesterol (LDL-C) were significantly lowered and their decreased percentages were significantly higher in therapy group ( < 0.05). The number of patients with arteria iliaca intima thickening was significantly lower in group of therapy ( = 0.024). With stepwise multivariate logistic regression analysis, the decreased percentage of TG was significantly and independently related with the decreased number of patients with arteria iliaca intima thickening ( = 0.005). The study demonstrates that therapy is effective on modulating dyslipidemia in newly diagnosed type 2 diabetes patients, and may be related with the improvement of early atherosclerosis.
