已研究脑脊液 (CSF) 生物标志物以区分 ALS 患者和神经系统对照患者,但未与临床上更相关的类似 ALS 的疾病进行比较。在这项回顾性研究中,分析了 ALS (n = 32) 和 ALS 模拟疾病 (n = 26) 患者的 CSF 浓度。神经丝轻链 (NFL) 和重链 (NFHp35) 的 CSF 浓度,但不是其他脑特异性蛋白ALS 患者中的蛋白质含量显着高于 ALS 模拟疾病患者,但最大敏感性或特异性为 80%。 ALS 组的 NFHp35 平均 CSF 水平为 781 ng/L,而模拟 ALS 疾病组为 338 ng/L,NFL 的平均 CSF 水平为 62 ng/L vs. 24 ng/L。尽管 ALS 患者的 CSF 中 NFL 和 NFHp35 浓度较高,但区分 ALS 与 ALS 模拟疾病的诊断准确性似乎不足。我们的结果表明,在疑似 ALS 患者的临床检查中,单独应用脑脊液分析是有限的,但与其他临床和电生理标志物结合使用可能具有潜力。
Cerebrospinal fluid (CSF) biomarkers have been studied to differentiate between patients with ALS and neurological controls, but not in comparison to clinically more relevant disorders mimicking ALS.In this retrospective study, CSF concentrations of various brain-specific proteins were analyzed in patients with ALS (n = 32) and ALS-mimic disorders (n = 26).CSF concentrations of neurofilament light (NFL) and heavy chain (NFHp35), but not other brain-specific proteins, were significantly higher in patients with ALS than in patients with an ALS-mimic disorder, however with maximum sensitivity or specificity of 80 %. The mean CSF level of NFHp35 was 781 ng/L in the ALS group vs. 338 ng/L in the ALSmimic disorders group and for NFL the mean CSF levels were 62 ng/L vs. 24 ng/L.Although CSF concentrations of NFL and NFHp35 are higher in patients with ALS, the diagnostic accuracy for differentiating ALS from ALS-mimic disorders seems insufficient. Our results suggest that, in the clinical work-up of patients suspected of ALS, application of CSF analysis alone is limited but may have potential in combination with other clinical and electrophysiological markers.
