 荷兰一项研究表明,血浆簇集蛋白(clusterin)水平与阿尔茨海默病(AD)的基线患病率及严重程度显著相关,但与AD的发病率无关。论文发表于《美国医学会杂志》[JAMA 2011,305(13):1354]。

  研究者检测了60例AD患者的基线血浆簇集蛋白浓度,以及随机子队列926例参试者和随访过程中156例新发AD患者的血浆簇集蛋白浓度。

  结果为,AD的患病率随血浆簇集蛋白浓度升高而增高[经校正年龄、性别、载脂蛋白E状况、糖尿病、吸烟、冠心病和高血压等因素后,血浆簇集蛋白每增加一个标准差(SD)的比值比(OR)=1.63]。经简易精神状态检查(MMSE)量表评估显示,在AD患者中,簇集蛋白水平与疾病的严重程度呈正相关(当血浆簇集蛋白每增加一个SD时,MMSE评分的校正后差异=-1.36,P = 0.047)。

  随访期间未发现血浆簇集蛋白浓度与AD发病率相关 (P=0.77)。
