JAHA:脑白质结构与淀粉样蛋白沉积的关系

2021-08-26 MedSci原创 MedSci原创

在没有痴呆的老年人中,白质高信号与淀粉样蛋白升高之间存在中等的正相关性。

白质异常是衰老和阿尔茨海默病的共同特征,在黑人中往往更为严重。然而,白质异常与淀粉样蛋白沉积(阿尔茨海默病病理标志物)之间的相关程度仍未明确。

近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,这项横断面研究旨在评估了社区样本中没有痴呆的老年人白质异常与皮质淀粉样蛋白之间的关联,并评估了人种的调节效应。

社区动脉粥样硬化风险-正电子发射断层扫描(ARIC-PET)研究的参与者进行了脑磁共振成像检查,并使用弥散张量成像量化了白质高信号体积和微观结构的完整性。参与者接受了florbetapir正电子发射断层扫描成像以测量脑淀粉样蛋白。研究人员使用多变量Logisitc回归评估了白质结构指标与淀粉样蛋白状态升高之间的关联。

在322名参与者(43%黑人)中,调整了人口统计学和心血管风险后,白质高信号体积每增加一个SD都与淀粉样蛋白升高之间更大的几率相关(比值比[OR]为1.37;95%CI为1.03-1.83)。在种族分层分析中,与白人参与者(OR为1.29;95%CI为0.89-1.89)相比,黑人参与者中较大的白质高信号体积与淀粉样蛋白升高之间的相关性更强(OR为2.00;95%CI为1.15-3.50)。然而,人种相互作用在统计学上并不显著(相互作用P=0.09)。研究人员发现白质微结构与淀粉样蛋白升高之间没有关联。

该研究的结果表明,在没有痴呆的老年人中,白质高信号与淀粉样蛋白升高之间存在中等的正相关性。尽管结果表明这种关联在黑人参与者中并不显著更强,但需要使用更大型的多种族队列来证实或反驳这些结果。
