B lymphocytes cause post-stroke cognitive decline in mice. We therefore evaluated the association between autoantibodies and post-stroke cognitive decline in a prospectively collected human cohort. The mini-mental state exam (MMSE) was administered 30, 90, 180, and 365days after stroke. Antibody titers to myelin basic protein (MBP), proteolipid protein, and several non-specific proteins were determined. Among 58 subjects with initial MMSE≥20 and at least 2 MMSE examinations in the year after stroke, cognitive decline (MMSE decrease ≥2) occurred in 10 (17%) subjects. In multivariate analysis, MBP antibody titers were the only independent predictor of cognitive decline (OR=9.02 [1.18, 68.90]; P=0.03).
B淋巴细胞会导致小鼠中风后认知功能下降。因此,我们在一个前瞻性收集的人类队列中评估了自身抗体与中风后认知功能下降之间的关联。在中风后30、90、180和365天进行简易精神状态检查(MMSE)。测定了针对髓鞘碱性蛋白(MBP)、蛋白脂蛋白和几种非特异性蛋白的抗体滴度。在58名初始MMSE≥20且在中风后一年内至少进行2次MMSE检查的受试者中,10名(17%)受试者出现了认知功能下降(MMSE降低≥2)。在多变量分析中,MBP抗体滴度是认知功能下降的唯一独立预测因素(OR=9.02 [1.18, 68.90];P=0.03)。
