正临床孤立综合征(clinicauy isolated syndrome,CIS)为多种脱髓鞘疾病的首发表现,是指在排除其他疾病的情况下,中枢神经系统脱髓鞘事件的急性或亚急性单次发作,持续时间在24h以上,有多发性硬化、视神经脊髓炎、横贯性脊髓炎、急性播散性脑脊髓炎等多种转归。由于这些疾病的最优化治疗方案和预后明显不同,CIS的早期鉴别诊断和预测转归具有非常重要的意义。

最近一期的JAMA Neurology杂志上的一篇研究发现,脑脊液中的可溶性CD27水平或可预测CIS向多发性硬化(MS)的进展。研究主要内容如下:

来自荷兰的研究团队对在2002.3-2015.5间收治在MS三级转诊中心的77名CIS患者,进行了一项前瞻性研究。这些CIS患者均在首次发病后的6个月内进行过腰椎穿刺和MRI检查。

研究人员通过酶联免疫吸附剂测定法(enzyme linked immunosorbent assay,ELISA)测定脑脊液中可溶性CD27的水平;使用Cox回归分析来计算诊断为MS的单变量和多变量的危险比;通过负二项回归模型评估可溶性CD27水平和复发率之间的关系。

研究人员发现:77名CIS患者中,50名为女性(占比79.5%),平均年龄32.7岁(标准差SD,7.4)。对照组,平均(SD)年龄为33.4(9.5)岁,20名女性(66.7%)。CIS患者的脑脊液中的可溶性CD27水平比对照组更高(几何平均数[geometric mean],31.3 U/ml;95% CI,24.0-40.9 VS平均,4.67 U/ml;95% CI,2.9-7.5;P <0. 001)。

在平均(SD)54.8(35.1)个月的随访中,77名患者中的39例患者(50.6%)被诊断为MS。在MRI检查和脑脊液测量方法的调整模型中,可溶性CD27水平与被诊断为MS相关(可溶性CD27水平每增加100 U/mL的危险比,2.4;95% CI,1.27-4.53;P =0.007)  。此外,MS患者中,在诊断为CIS时有高水平可溶性CD27(中位数> 31.4 U/ml)患者的年复发率是低水平者的5.5倍(年复发率,0.33 vs 0.06;P = 0.02)。

研究人员认为,临床孤立综合征患者脑脊液中可溶性CD27与多发性硬化的诊断和高复发率相关。因此,可溶性CD27与疾病的免疫病理学直接相关的一种活化分子,是有利于首发表症状疑似多发性硬化患者的诊治的潜在临床标志物。
