摘要:

肌萎缩侧索硬化的特征是运动神经元的进行性丧失,且早期轴突功能障碍在疾病过程中起着重要的作用。然而,这种功能障碍背后的分子机制尚不清楚。为了解肌萎缩侧索硬化患者外周免疫失调与轴突功能障碍之间的关系,此次队列研究于2018年1月至2024年5月在北京大学第三医院招募了发病12个月内的372例散发性肌萎缩侧索硬化患者,收集外周血免疫标志物,包括总白细胞、淋巴细胞、单核细胞、中性粒细胞、嗜碱性粒细胞、嗜酸性粒细胞和血小板,并计算4种衍生比值(中性粒细胞与淋巴细胞比值、血小板与淋巴细胞比值、淋巴细胞与单核细胞比值以及全身免疫炎症指数)。调整混杂因素后的多变量分析结果显示,在早期肌萎缩侧索硬化患者中,较高的白细胞计数、中性粒细胞计数以及中性粒细胞相关衍生比值(中性粒细胞与淋巴细胞比值(NLR)和全身免疫炎症指数(SII))与较高的复合肌肉动作电位评分显著相关。进一步分层分析说明,这些关联因年龄和性别而异。此外,中介分析表明,轴突功能障碍在免疫标志物与疾病进展之间的关系中起着重要作用。这些发现提示,外周免疫失调可通过介导周围神经损伤在肌萎缩侧索硬化进展中起重要作用,特别是在疾病的早期阶段。

Abstract: Amyotrophic lateral sclerosis is characterized by the progressive loss of motor neurons. Early-stage axonal dysfunction, rather than central nervous system injury, plays a key role in the disease process. However, the molecular mechanisms underlying this dysfunction remain unclear. To investigate the relationship between peripheral immune dysregulation and axonal dysfunction in amyotrophic lateral sclerosis, we recruited 372 patients within the first 12 months of sporadic amyotrophic lateral sclerosis onset between January 2018 and May 2024. We collected peripheral immune markers at baseline, including total leukocytes, lymphocytes, monocytes, neutrophils, basophils, eosinophils, and platelets. We also calculated four derived ratios: neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and systemic immune inflammation index. Multivariate analysis, adjusted for confounding factors, revealed that higher counts of total leukocytes and neutrophils, as well as higher neutrophil-related ratios, including the neutrophil to lymphocyte ratio and the systemic immune inflammation index, were significantly correlated with higher compound muscle action potential scores. Stratified analyses revealed that these associations varied by age and sex. Furthermore, mediation analysis demonstrated that axonal dysfunction plays a significant role in the relationship between immune markers and disease progression. These findings emphasize the critical role that peripheral immune dysregulation plays in amyotrophic lateral sclerosis progression by mediating peripheral nerve injury, particularly in the early stages of the disease. This study highlights the importance of the peripheral nervous system in the early stages of amyotrophic lateral sclerosis and provides new insights into disease mechanisms and potential therapeutic targets.
