背景和目的 血小板在缺血性脑血管疾病(CVD)的发展中发挥着关键作用。血小板糖蛋白 (GP) Ib/IX/V 复合物是冯·维勒布兰德因子的受体,在高剪切应力条件下血小板活化的初始阶段起主要作用。本研究旨在调查该受体的遗传变异与 CVD 患病率之间的关联。 方法 分析了 200 名经脑部 CT 和/或 MRI 证实的缺血性 CVD 患者,以及 317 名没有 CVD 或心血管疾病临床证据的年龄和性别匹配的对照受试者,分析其 GPIb α 链 (GPIbalpha) 的 (145)Thr/Met 二态性基因型频率。 结果 (145)Met 基因型(T/M 和 M/M)在 CVD 患者 (26.5%) 中比对照受试者 (14.2%, P=0.0005) 更常见。基因型效应在<60岁或无后天性心血管危险因素的人群中更为明显。 60 岁以下不吸烟女性的比值比为 10. 6(95% 置信区间,2.2 至 51.7)。尽管研究的患者人数较少(n = 24),但短暂性脑缺血发作的比值比最高(4.3,P = 0.0004),其次是腔隙性梗死(OR = 2.2,P = 0.0024)和动脉粥样硬化性梗死(OR = 1. 5,P = 0.3143)。 Logistic 回归分析显示,Met 等位基因的存在与 CVD 独立相关。 结论 我们的研究表明血小板 GPIbalpha 基因型是缺血性 CVD 的遗传危险因素。
BACKGROUND AND PURPOSE Platelets play pivotal roles in the development of ischemic cerebrovascular disease (CVD). The platelet glycoprotein (GP) Ib/IX/V complex is a receptor for von Willebrand factor, which plays a major role in the initial phase of platelet activation under high shear stress conditions. This study was designed to investigate the association between a genetic variation of this receptor and the prevalence of CVD. METHODS Two hundred patients with ischemic CVD, as confirmed by brain CT and/or MRI, and 317 age- and sex-matched control subjects without clinical evidence of CVD or cardiovascular disease were analyzed for their genotype frequencies of the (145)Thr/Met dimorphism of the alpha-chain of GPIb (GPIbalpha). RESULTS Genotypes with (145)Met (T/M and M/M) were more frequently found in the CVD patients (26.5%) than in control subjects (14.2%, P=0.0005). The genotype effect was more obvious in those <60 years of age or without acquired cardiovascular risk factors. The odds ratio for nonsmoking women <60 years of age was 10. 6 (95% confidence intervals, 2.2 to 51.7). Although the number of patients studied was small (n=24), transient ischemic attack showed the highest odds ratio (4.3, P=0.0004), followed by lacunar infarction (OR=2.2, P=0.0024) and atherothrombotic infarction (OR=1. 5, P=0.3143). Logistic regression analysis revealed that the presence of Met-allele was independently associated with CVD. CONCLUSIONS Our study suggests that the platelet GPIbalpha genotype is a genetic risk factor for ischemic CVD.
