Abstract
OBJECTIVES:Cerebrospinal fluid (CSF) and blood neurofilaments (NFLs) are markers of axonal damage and are being investigated, mostly in relapsing-remitting (RR) MS, as a marker of disease activity and of response to treatment, while there are less data in progressive MS patients. Primary aim was to measure NFL in plasma samples of untreated patients with primary (PP) and secondary (SP) progressive MS and to correlate them with disability, disease severity, and prior/subsequent disability progression. MATERIALS AND METHODS:Neurofilament concentrations were measured using SIMOA (Single Molecule Array, Simoa HD-1 Analyzer; Quanterix). RESULTS:Neurofilament concentrations were measured on plasma samples of 70 progressive (27 PP and 43 SP), 21 RRMS patients, and 10 HCs. Longitudinal plasma NFL (pNFL) concentrations (median interval between sampling: 25 months) were available for nine PP/SP patients. PNFL concentrations were significantly higher in PP/SP compared to RRMS patients. They correlated with EDSS and MS Severity Score values. There was no difference in pNFL levels between PP/SP patients with EDSS progression in the preceding year (14% of patients) or during a median follow-up of 27 months (41%). In the longitudinal sub-study, pNFL levels increased in all patients between sampling by a mean value of 23% while EDSS mostly remained stable (77% of cases). CONCLUSION:In PP/SP progressive MS patients, pNFL levels correlate with disability and increase over time, but are not associated with prior/subsequent disability progression, as measured by EDSS, which may not be a sufficiently sensitive tool in this context.
摘 要
目的: 脑脊液 (CSF) 和血液神经丝 (NFLs) 是轴突损伤的标志物,目前正在研究中,主要是复发-缓解 (RR) MS,作为疾病活动和治疗反应的标志物,而在进行性MS患者中数据较少。主要目的是测量橄榄球联盟 (NFL) 的血浆样品中的未经治疗的原发性肝癌患者 (PP) 和第二 (SP) 进行性MS,并将其关联残疾、疾病严重程度,和之前/随后的残疾进展。 材料和方法: 使用SIMOA (单分子阵列,Simoa HD-1 分析仪; Quanterix) 测量神经丝浓度。 结果: 神经微丝蛋白浓度测定血浆样品的 70 例,进展 (27 页 43 SP),21 例RRMS患者,10 HCs.纵向等离子体NFL (pNFL) 浓度 (中位间隔采样: 25 个月) 可供九PP/SP.PNFL浓度显著高于PP/SP相比RRMS患者.他们与EDSS和MS严重度评分值.无差异pNFL水平PP/SP患者EDSS进展前一年 (14%) 或在平均随访 27 个月 (41%).在纵向子研究中,所有患者的pNFL水平在取样之间增加了 23% 的平均值,而EDSS大部分保持稳定 (77% 的病例)。 结论: 在PP/SP进行性MS患者中,pNFL水平与残疾和随着时间的推移而增加,但不与前/后残疾进展来衡量,EDSS,在这种情况下,这可能不是一个足够敏感的工具。
