| 目的 系统评价静脉滴注免疫球蛋白(intravenous immunoglobulin,IVIG)维持治疗多发性硬化(multiple sclerosis,MS)的临床疗效.方法 采崩Cochrane系统评价方法,通过电子检索MEDLINE、EMbas、CBMdisc、Cochrane Library、ISI和美国临床试验登记中心等的数据库文献(1990～2008).评价纳入文献的方法学质量后,采用RevMan 4.2.10软件对提取的数据进行分析.结果 共纳入10个随机对照试验研究.IVIG治疗组与安慰剂组比较,研究期限内复发缓解型多发性硬化(relapsing-remitting muhiple sclerosis,RRMS)患者的复发状况差异有统计学意义(P=0.04,OR:0.40.95%CI=0.19～0.86),RRMS患者EDSS评分的变化差异有统计学意义(P＜0.0001,WMD=-0.27,95%CI=-0.40～-0.13),不同剂量IVIG(每个月0.2 g/kg与0.4 g/kg)治疗RRMS的复发状况比较差异无统计学意义(P=0.69,OR=1.16,95%CI=0.56～2.41);IVIG与干扰素-β1a治疗RRMS的疗效比较,显示二者均能降低疾病的复发率,二者之间无统计学差异(P＞0.1),而在治疗前后EDSS评分的比较中,仅IVIG治疗前后的差异有统计学意义.IVIG治疗组与安慰剂组比较,研究期限内进展型MS患者的疾病进展状况差异无统计学意义(P=0.32,OR=0.68,95%CI=0.31～1.46),继发进展型多发性硬化(secondary-progressivemultiple sclerosis,SPMS)患者的复发状况差异无统计学意义(P=0.70,OR=0.93,95%CI=0.66～1.32).结论 IVIG用于维持治疗MS,其安全性好,可降低RRMS的复发率及EDSS评分显示的神经功能障碍.不同剂量的IVIG治疗RRMS无剂量-效应关系.IVIG与干扰素-β1a均能降低RRMS的复发率,IVIG改善神经功能方面的疗效优于低剂量的干扰素-β1a.目前尚不能认为IVIG用于进展型MS的维持治疗可以阻止疾病的进展及复发.
