文摘目的探讨免疫吸附对视神经脊髓炎谱系病(neuromyelitis optica spectrum disorder,NMOSD)急性期的治疗效果。方法对15例对大剂量糖皮质激素治疗反应不佳的NMOSD急性发作期患者,进行免疫吸附治疗5次,比较治疗前后的扩展残疾评分量表(expanded disability status scale,EDSS)、视力分层、水通道蛋白4(aquaporin 4,AQP4)抗体水平、免疫球蛋白及补体变化。结果15例患者免疫吸附治疗后相对于治疗前的EDSS评分〔4.0(3.0,6.0)比4.5(3.0,6.5),t=2.640,P=0.008〕、AQP4抗体水平〔(16.27±22.40)u/mL比(45.24±32.97)u/mL,t=4.011,P=0.002〕均显著降低。10例患者共15只眼出现视神经炎,治疗后视力均较治疗前显著改善〔视力分层4.0(3.0,5.0)比5.0(3.0,7.0),t=2.872,P=0.007〕。免疫吸附治疗后较治疗前补体C3水平〔(0.53±0.20)g/L比(1.02±0.22)g/L,t=6.588,P=0.001〕、补体C4水平〔(0.12±0.34)g/L比(0.20±0.06)g/L,t=5.597,P=0.001〕均显著下降。15例患者中5例出现轻度不良反应,4例患者在免疫吸附治疗3次后出现纤维蛋白原降低,经输注纤维蛋白原1 g 1次后改善;1例患者首次治疗中曾发生一过性低血压,补液治疗后缓解;无重度不良事件发生。结论免疫吸附治疗可有效改善NMOSD患者临床神经功能及视力,降低AQP4抗体水平。免疫吸附治疗安全性良好。
