脑脊液(CSF)中的磷酸化tau(p-tau)是一种已确立的阿尔茨海默病(AD)生物标志物。靶向N末端和中间区p-tau 181和p-tau 217片段的新型免疫测定法是可用的,但缺乏临床环境中的头对头比较。在3个队列(n = 503)中评价了CSF中的N-末端定向p-tau 217(N-p-tau 217)、N-末端定向p-tau 181(N-p-tau 181)和标准中间区p-tau 181(Mid-p-tau 181)生物标志物,以评估诊断性能、一致性和与β淀粉样蛋白(Aβ)的相关性。CSF N-p-tau 217和N-p-tau 181的一致性(88.2%)优于Mid-p-tau 181(79.7%-82.7%)。N-p-tau 217和N-p-tau 181在早期轻度认知障碍(MCI)-AD(A+T-N-)中显著增加,而Mid-p-tau 181没有变化,直到AD-痴呆。N-p-tau 217和N-p-tau 181识别Aβ病理生理学(曲线下面积[AUC] = 94.8%-97.1%),区分MCI-AD和非AD MCI(AUC = 82.6%-90.5%)的效果显著优于Mid-p-tau 181(AUC分别为91.2%和70.6%)。P-tau生物标志物同样区分AD和非AD痴呆(AUC = 99.1%-99.8%)。N-p-tau 217和N-p-tau 181可以提高前驱期AD和临床试验招募的诊断准确性,因为两者都能识别Aβ病理生理学,并区分早期MCI-AD,优于Mid-p-tau 181。
Phosphorylated tau (p‐tau) in cerebrospinal fluid (CSF) is an established Alzheimer's disease (AD) biomarker. Novel immunoassays targeting N‐terminal and mid‐region p‐tau181 and p‐tau217 fragments are available, but head‐to‐head comparison in clinical settings is lacking. N‐terminal‐directed p‐tau217 (N‐p‐tau217), N‐terminal‐directed p‐tau181 (N‐p‐tau181), and standard mid‐region p‐tau181 (Mid‐p‐tau181) biomarkers in CSF were evaluated in three cohorts (n = 503) to assess diagnostic performance, concordance, and associations with amyloid beta (Aβ). CSF N‐p‐tau217 and N‐p‐tau181 had better concordance (88.2%) than either with Mid‐p‐tau181 (79.7%–82.7%). N‐p‐tau217 and N‐p‐tau181 were significantly increased in early mild cognitive impairment (MCI)‐AD (A+T–N–) without changes in Mid‐p‐tau181 until AD‐dementia. N‐p‐tau217 and N‐p‐tau181 identified Aβ pathophysiology (area under the curve [AUC] = 94.8%–97.1%) and distinguished MCI‐AD from non‐AD MCI (AUC = 82.6%–90.5%) signficantly better than Mid‐p‐tau181 (AUC = 91.2% and 70.6%, respectively). P‐tau biomarkers equally differentiated AD from non‐AD dementia (AUC = 99.1%–99.8%). N‐p‐tau217 and N‐p‐tau181 could improve diagnostic accuracy in prodromal‐AD and clinical trial recruitment as both identify Aβ pathophysiology and differentiate early MCI‐AD better than Mid‐p‐tau181.
