科学领域:

  • 神经学 神经学
  • 生物标志物 生物标志物
  • 肌缩侧面硬化症 (ALS) 是一种疾病.

背景情况:

  • 分裂肘标志 (SES),表明偏好的双臂部功能障碍超过三脚,是肌缩侧面硬化症 (ALS) 的公认临床特征.
  • SES指数的量化及其在ALS的诊断实用性尚未被彻底探讨.

研究的目的:

  • 在ALS患者中使用复合肌动力潜力 (CMAP),运动单元数指数 (MUNIX) 和回声强度 (EI) 调查分肘指数 (SEI).
  • 评估SEI在区分ALS与对照病的诊断性能及其与疾病进展的相关性.

主要方法:

  • 该研究包括70名ALS患者,41名疾病对照者和40名健康对照者.
  • SEI的计算方法是将双肩值除以CMAP,MUNIX和EI的三值 (SEI,MUNIX,EI).
  • 用接收器操作特征 (ROC) 曲线来评估诊断性能.

主要成果:

  • 与对照组相比,ALS患者的SEICMAP和SEIMUNIX显著减少 (P < 0.0001).与对照组相比,ALS患者的SEICMAP和SEIMUNIX显著减少 (P < 0.0001).
  • 在ALS患者中,SEIEI显著升高 (P < 0.0001).
  • SEIMUNIX显示疾病进展显著下降 (P <0.001),其ROC分析产生了最高的AUC (0.846). 一种综合的SEI方法实现了AUC为0.90.

结论:

  • 作为ALS诊断的重要生物标志物,SES指标显示出有前途.
  • 量化SEI指标可以帮助评估疾病进展,并可能作为ALS的诊断生物标志物.
