BACKGROUND/AIMS: Recent experimental research revealed that statins at low doses induce angiogenesis, which in turn may be related to the course of atherosclerosis. There are no clinical studies evaluating the effect of 'low-dose' statins on serum levels of angiogenesis regulators in diabetic subjects. We aimed to explain how low doses of statins modify the serum concentrations of two potent proangiogenic factors, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), in patients with type 2 diabetes.
Measurements of fasting glucose level, HbA1c, 1,5-anhydro-D-glucitol and lipid profile were taken from 47 patients with type 2 diabetes treated with low doses of atorvastatin (10 mg daily) or simvastatin (10-20 mg daily), from 45 statin-free patients with type 2 diabetes and from 23 nondiabetic subjects. Measurements of VEGF and bFGF in serum were taken using the BD™ Cytometric Bead Array.
Statins used in low doses in patients with type 2 diabetes reduce the serum concentration of VEGF and bFGF which suggests antiangiogenic potential of these doses. Nevertheless, this effect could be neutralized by postprandial hyperglycemia.
背景/目的:近期实验研究表明,低剂量他汀类药物可诱导血管生成,这可能与动脉粥样硬化进程相关。目前尚无临床研究评估“低剂量”他汀类药物对糖尿病患者血清血管生成调节因子水平的影响。我们旨在阐明低剂量他汀类药物如何改变2型糖尿病患者血清中两种强效促血管生成因子——血管内皮生长因子(VEGF)和碱性成纤维细胞生长因子(bFGF)的浓度。
对47例接受低剂量阿托伐他汀(每日10毫克)或辛伐他汀(每日10 - 20毫克)治疗的2型糖尿病患者、45例未使用他汀类药物的2型糖尿病患者以及23例非糖尿病受试者进行空腹血糖水平、糖化血红蛋白(HbA1c)、1,5 - 脱水-D-葡萄糖醇和血脂谱测量。使用BD™细胞计数微球阵列检测血清中的VEGF和bFGF。
2型糖尿病患者使用低剂量他汀类药物可降低血清VEGF和bFGF浓度,提示这些剂量具有抗血管生成潜力。然而,这种作用可能会被餐后高血糖抵消。
