Abstract

Objectives: Changes in the locus coeruleus are among the earliest events in Alzheimer's disease (AD). We aimed to evaluate the relationship between cerebrospinal fluid (CSF) L-dihydroxyphenylalanine (L-DOPA), dopamine, and norepinephrine with CSF biomarkers of AD pathology (β-amyloid and p-tau), neuronal destruction (neurofilaments), and inflammation (leukocytes, IgG index, interleukin-6 and 10).

Methods: We conducted a cross-sectional, observational study, including 35 patients with AD, 16 with frontotemporal dementia, and 38 normal controls (NC).

Results: L-DOPA was lower (p = 0.032) and neurofilaments were higher (p = 0.005) in AD than in NC. Norepinephrine levels were positively correlated with age (r = 0.260, p = 0.015 among all patients). L-DOPA levels were negatively correlated with neurofilaments (r = -0.228, p = 0.038 among all participants). Interleukin-6 was positively correlated with L-DOPA (r = 0.382, p = 0.026) and norepinephrine (r = 0.485, p = 0.004) levels in AD.

Conclusion: Since neurofilaments are associated with neuronal damage, decreased L-DOPA levels in AD could be related to neuronal destruction. Catecholaminergic dysregulation seen in AD seems independent of β-amyloid and p-tau pathology.

脑脊液儿茶酚胺水平与阿尔茨海默病、炎症和神经元损伤生物标志物的关系

目的：蓝斑的改变是阿尔茨海默病（AD）的早期事件之一。我们旨在评估脑脊液（CSF） l -二羟基苯丙氨酸（L-DOPA）、多巴胺和去甲肾上腺素与阿尔茨海默病脑脊液生物标志物（β-淀粉样蛋白和p-tau）、神经元破坏（神经丝）和炎症（白细胞、IgG指数、白细胞介素-6和10）之间的关系。方法：我们进行了一项横断面观察性研究，包括35例AD患者，16例额颞叶痴呆患者和38例正常对照（NC）。结果：AD组左旋多巴含量低于NC组（p = 0.032），神经纤维含量高于NC组（p = 0.005）。去甲肾上腺素水平与年龄呈正相关（r = 0.260, p = 0.015）。左旋多巴水平与神经丝呈负相关（r = -0.228, p = 0.038）。白细胞介素-6与AD患者L-DOPA （r = 0.382, p = 0.026）、去甲肾上腺素（r = 0.485, p = 0.004）水平呈正相关。结论：神经丝与神经元损伤有关，AD患者左旋多巴水平降低可能与神经元损伤有关。在AD中看到的儿茶酚胺能失调似乎与β-淀粉样蛋白和p-tau病理无关。
