与安慰剂相比,盐酸倍他司汀对于梅尼埃病患者的眩晕发作的长期疗效是怎样的呢?

该BEMED试验是一项多中心、双盲、随机、安慰剂对照、三臂、平行组、III期、剂量限定的优效性试验,在德国的14个三级转诊中心(神经内科或耳、鼻、喉)进行。年龄在21-80岁(平均年龄56岁),被确定为单侧或双侧梅尼埃病的成年人在2008年3月2012年11月之间被招募参与此研究,这些参加者接受安慰剂(n=74),或低剂量的倍他司汀(2×24mg/天,n=73),或高剂量的倍他司汀(3×48mg/天,n=74)超过九个月。主要终点是在三个月考核期里的每30天的发病次数,根据患者七到九个月之间的日志进行确定。基于互联网的随机化时间表进行隐蔽的1:1:1分配,通过研究点进行分层。次要终点包括持续时间和严重程度,生活质量评分变化,和几个观测报告的参数来评估听力学及前庭功能的变化。

三个治疗组之间与梅尼埃病相关的发病率没有差异(P=0.759)。与安慰剂相比,低剂量和高剂量的倍他司汀发病率比分别为1.036(95%可信区间0.942至1.140)和1.012(0.919至1.114)。总体月度发病率显著下降到0.758(0.705到0.816,P<0.001)。以人群为基础的,评估期内的月平均发病率在安慰剂组、低剂量的倍他司汀组和高剂量倍他司汀组分别为2.722(1.304至6.309)、3.204(1.345至7.929)以及3.258(1.685至7.266)。所有的次要结果都是一致的。治疗耐受性良好,没有意外的安全性结果。在疾病的自然病程中,对照组的患者都接受了干预,安慰剂效应在自发缓解和症状波动区不能被准确评估和区分。

目前的证据被限制为,与安慰剂相比,倍他司汀是否可防止因梅尼埃病眩晕发作。该试验提供了梅尼埃病患者相关的症状缓解,和潜在的疾病治疗方法改变相关的安慰剂干预的信息,这有利于未来的研究方向。
