本研究的目的是调查脑脊液 (CSF) 中 tau、磷酸化 tau、β-淀粉样蛋白 42、α-突触核蛋白、神经丝光和 YKL-40 的水平是否随时间变化,以及这些变化是否与 PD 患者和对照组的运动进展和/或认知能力下降相关。我们纳入了瑞典 BioFINDER 前瞻性纵向研究中的 63 名 PD 患者(非痴呆)和 21 名神经健康对照者,所有这些人在基线时和 2 年后均接受了临床评估和腰椎穿刺。 CSF tau 水平与 α-突触核蛋白密切相关。 PD 患者 CSF 中 α-突触核蛋白、tau、磷酸化 tau、神经丝轻链和 YKL-40(而非 β-淀粉样蛋白 42)水平在 2 年内增加。对照组没有看到任何变化。分别研究病程短(≤≤5年)的患者和病程长(≥5年)的患者,α-突触核蛋白和tau仅在病程长的PD组中增加。在 PD 组中,两年内磷酸化 tau 蛋白的增加与更快的运动进展和更快的认知能力下降相关。两年内 YKL-40 的增加与认知能力下降更快相关。反映路易体病理学和神经变性(α-突触核蛋白)、神经元变性(tau、磷酸化 tau 和神经丝光)和炎症 (YKL-40) 的脑脊液生物标志物在 PD 患者中在 2 年内显着增加。脑脊液中 α-突触核蛋白和 tau 蛋白的水平在 PD 早期症状阶段相关并保持稳定,但在后期阶段增加。我们假设,病程较长的帕金森病中神经退行性变更严重,导致脑脊液 α-突触核蛋白水平可能升高。 © 2016 作者。 《运动障碍》由 Wiley periodicals, Inc. 代表国际帕金森和运动障碍协会出版
The purpose of this study was to investigate whether cerebrospinal fluid (CSF) levels of tau, phosphorylated tau, β‐amyloid42, α‐synuclein, neurofilament light, and YKL‐40 change over time and if changes correlate with motor progression and/or cognitive decline in patients with PD and controls. We included 63 patients with PD (nondemented) and 21 neurologically healthy controls from the prospective and longitudinal Swedish BioFINDER study, all of whom had clinical assessments and lumbar punctures at baseline and after 2 years. CSF tau levels correlated strongly with α‐synuclein. The levels of CSF α‐synuclein, tau, phosphorylated tau, neurofilament light, and YKL‐40, but not β‐amyloid42, increased in CSF over 2 years in PD. No changes were seen in the control group. Studying patients with a short disease duration ( ≤ 5 years) and patients with a long disease duration ( > 5 years) separately, α‐synuclein and tau only increased in the PD group with long disease duration. In the PD group, an increase in phosphorylated tau over 2 years correlated with faster motor progression and faster cognitive decline. An increase in YKL‐40 over 2 years correlated with faster cognitive decline. CSF biomarkers reflecting Lewy body pathology and neurodegeneration (α‐synuclein), neuronal degeneration (tau, phosphorylated tau, and neurofilament light), and inflammation (YKL‐40) increase significantly over 2 years in PD. CSF levels of α‐synuclein and tau correlate and remain stable in the early symptomatic phase of PD but increase in the later phase. We hypothesize that CSF α‐synuclein levels might increase as a result of more intense neurodegeneration in PD with long disease duration. © 2016 The Authors.
