Lancet:抗抑郁药米氮平治疗痴呆患者激进行为的效果研究

2021-10-23 MedSci原创 MedSci原创

痴呆症是我们这个时代最常见和最严重的公共卫生问题之一。

痴呆症是我们这个时代最常见和最严重的公共卫生问题之一。全世界有超过4600万人患有痴呆症,这一数字在未来20年将翻一番。伴随着这种认知和功能的下降,个人可能会出现神经精神症状,如激进行为、睡眠障碍、抑郁症和精神病。

近一半的阿尔茨海默病(AD)患者在一个月内受到影响,而80%有临床症状的患者在6个月后仍有症状。激进行为与家人和专业护理人员的关系恶化、入住护理院、护理费用增加、护理人员负担和倦怠以及生活质量下降有关。

目前关于更安全和有效的抗精神病药物替代品的证据很少。米氮平是一种用于治疗痴呆症躁动的抗抑郁药,为了评估了米氮平的安全性和疗效,来自普利茅斯大学卫生学院的专家开展了相关研究,结果发表在Lancet杂志上。

这项平行组、双盲、安慰剂对照的试验--米氮平治疗痴呆症激动行为的研究试验(SYMBAD)--在英国26个中心进行。参与者可能或可能患有AD,对非药物治疗无反应的激动行为,以及科恩-曼斯菲尔德激动量表(CMAI)得分45以上。他们被随机分配(1:1)接受米氮平(滴定到45mg)或安慰剂。主要结果是在12周时CMAI评分的减少。

结果显示,在2017年1月26日至2020年3月6日期间,招募了204名参与者并进行了随机分组。接受米氮平的参与者和接受安慰剂的参与者在12周时的平均CMAI评分没有明显差异(调整后的平均差异-1.74,95%CI-7.17至3.69)。

各治疗组未经调整的平均CMAI评分

同时,出现不良事件的对照组(102名对照组中的65名[64%])与米氮平组(102名接受米氮平的参与者中的67名[66%])的人数相似。然而,在第16周时,米氮平组(n=7)的死亡人数多于对照组(n=1),事后分析表明,这种差异的统计学意义不大。

综上,本研究的数据不支持使用米氮平作为痴呆症躁动的治疗手段。
