We determine the significant relation of HDL cholesterol and total cholesterol/HDL cholesterol between CETP I405V genotypes and activity of CETP. CETP is an essential for transfer of cholesterol ester to the liver from peripheral tissues which facilitating its transfer to TG rich VLDL. Reduction activity of CETP I405V may associate with genotypes of CETP I405V. This study is undertaken to assess the presence and impact of CETP I405V genotype in our population.
In this study 100 acute myocardial infarction patients and 100 normal age & sex matched healthy individuals were included. Serum Lipid profile was estimated by using universal standard methods whereas CETP I405V genotype was studied by ARMS PCR.
There is presence of CETP 405Val genotype both in patient as well as in control group. RESULTs show that HDL cholesterol (p<0.0001) and ratio of total cholesterol/HDL cholesterol are significantly (p<0.0043) associated with Val/Val genotype. In addition to that the CETP I405V genotype is associated with inhibition of CETP activity with higher HDL-C level and decreased total cholesterol/HDL cholesterol ratio.
Our results show that the CETP I405V genotypes are very much significantly determinant of HDL cholesterol in patients with CHD.
我们确定CETP I405V基因型与CETP活性之间高密度脂蛋白胆固醇及总胆固醇/高密度脂蛋白胆固醇的显著关系。CETP对于胆固醇酯从外周组织向肝脏的转运至关重要,有助于其向富含甘油三酯的极低密度脂蛋白的转运。CETP I405V活性降低可能与CETP I405V的基因型有关。本研究旨在评估CETP I405V基因型在我们人群中的存在情况及其影响。
本研究纳入了100例急性心肌梗死患者和100例年龄及性别匹配的正常健康个体。采用通用标准方法估算血清脂质谱,而通过扩增阻滞突变系统聚合酶链反应(ARMS PCR)研究CETP I405V基因型。
患者组和对照组均存在CETP 405Val基因型。结果显示,高密度脂蛋白胆固醇(p<0.0001)以及总胆固醇/高密度脂蛋白胆固醇比值与Val/Val基因型显著相关(p<0.0043)。除此之外,CETP I405V基因型与CETP活性受抑制相关,表现为高密度脂蛋白胆固醇水平升高以及总胆固醇/高密度脂蛋白胆固醇比值降低。
我们的结果表明,CETP I405V基因型是冠心病患者高密度脂蛋白胆固醇的非常显著的决定因素。
