本研究在一个临床研究样本中检验了一组脑脊液(CSF)生物标志物对阿尔茨海默病(AD)生物标志物的补充作用。我们比较了按临床诊断以及pTau181/Aβ42状态(+/ -)划分的各组之间的生物标志物,并探讨了它们在预测认知方面的价值。 使用神经工具包(NTK)对720名年龄在40至93岁(平均年龄 = 63.9岁,标准差[SD] = 9.0;50名患有痴呆症;54名患有轻度认知障碍[MCI],616名未受损)的成年人测量了脑脊液生物标志物β - 淀粉样蛋白(Aβ)42、pTau181、总tau蛋白(tTau)、Aβ40、神经颗粒素、神经丝轻链(NfL)、α - 突触核蛋白、胶质纤维酸性蛋白(GFAP)、几丁质酶 - 3 - 样蛋白1(YKL - 40)、髓样细胞表达的可溶性触发受体2(sTREM2)、S100钙结合蛋白B(S100B)和白细胞介素6(IL6)。 与所有pTau181/Aβ42 - 的参与者相比,pTau181/Aβ42 + 的轻度认知障碍/痴呆参与者的神经退行性变和神经胶质激活生物标志物升高。在pTau181/Aβ42 + 的参与者中,神经退行性变生物标志物随着临床严重程度的增加而升高,并预示着更差的认知表现。神经胶质激活生物标志物与认知表现无关。 神经工具包包含有前景的标志物,可改善阿尔茨海默病的病理生理特征。总tau蛋白之外的神经退行性变生物标志物提高了对认知和疾病阶段的统计预测能力。
This study examines the utility of a multipanel of cerebrospinal fluid (CSF) biomarkers complementing Alzheimer's disease (AD) biomarkers in a clinical research sample. We compared biomarkers across groups defined by clinical diagnosis and pTau181/Aβ42 status (+/−) and explored their value in predicting cognition. CSF biomarkers amyloid beta (Aβ)42, pTau181, tTau, Aβ40, neurogranin, neurofilament light (NfL), α‐synuclein, glial fibrillary acidic protein (GFAP), chitinase‐3‐like protein 1 (YKL‐40), soluble triggering receptor expressed on myeloid cells 2 (sTREM2), S100 calcium binding protein B (S100B), and interleukin 6 (IL6), were measured with the NeuroToolKit (NTK) for 720 adults ages 40 to 93 years (mean age = 63.9 years, standard deviation [SD] = 9.0; 50 with dementia; 54 with mild cognitive impairment [MCI], 616 unimpaired). Neurodegeneration and glial activation biomarkers were elevated in pTau181/Aβ42+ MCI/dementia participants relative to all pTau181/Aβ42‐ participants. Neurodegeneration biomarkers increased with clinical severity among pTau181/Aβ42+ participants and predicted worse cognitive performance. Glial activation biomarkers were unrelated to cognitive performance. The NTK contains promising markers that improve the pathophysiological characterization of AD. Neurodegeneration biomarkers beyond tTau improved statistical prediction of cognition and disease stages.
