摘要 目的探讨阿尔茨海默病(AD)患者脑脊液磷酸化tau蛋白在诊断AD中的临床价值。方法选取AD患者31例(AD组),血管性痴呆患者38例(VD组)以及健康对照组30例。采用ELISA法检测三组患者的脑脊液磷酸化tau蛋白浓度,并分析其诊断AD的敏感度和特异度。结果 AD组患者脑脊液磷酸化tau蛋白浓度显著高于健康对照组和VD组患者(P<0.05),而VD组患者与健康对照组患者的磷酸化tau蛋白的浓度差异无统计学意义(P>0.05)。将脑脊液磷酸化tau蛋白的分界值定为60 ng/L,其诊断AD的敏感度为83.87%,特异度为89.47%,准确性为86.96%。结论脑脊液磷酸化tau蛋白可能成为AD重要的生物学标记物,可以为AD的诊断提供临床依据。
