Lancet Neurol:多发性硬化症的前驱症状

2017-04-21 zhangfan MedSci原创

研究发现多发性硬化症存在可衡量的前驱症状,有助于建立一个早期识别和治疗潜在的多发性硬化症的窗口

神经退行性疾病的退化过程可在临床表现出现前几年就已经开始。研究人员近日就多发性硬化症患者是否也存在早期前驱症状窗口期开展研究并希望在首次脱髓鞘事件发生前提早进行相关症状的治疗。

研究人员从加拿大的4个州获得相关的卫生行政与临床数据以比较在第一次脱髓鞘发生的5年前,医疗保险数据显示的多发性硬化症患者和一般病人在入院、医嘱和处方使用情况的差异。比率(RR)估计采用负二项式回归并结合各省情况使用随机效应模型。

在1984至2014年间,共有14428起多发性硬化病例以及72059对照病人的医疗保险纪录。研究发现第一次脱髓鞘事件前的5到1年,多发性硬化患者与对照者相比年医疗保险支出增长稳定(医院接诊RR:1.26-1.78,医嘱RR:1.24-1.88,处方RR:1.23-1.49)。临床症状相关的医嘱或处方情况也显示了相似的变化(3202名多发性硬化患者以及16006名一般患者)。

研究认为,在发生首次脱髓鞘事件的前5年,多发性硬化患者更频发地使用医疗保险,这说明存在一个可衡量的多发性硬化症的前驱症状。该发现具有极高的临床意义:有助于建立一个早期识别和治疗潜在的多发性硬化症的窗口。
