2018年12月,发表在《Lancet》的一项实效性、双盲、随机对照试验,考察了氟西汀对急性卒中后功能结局的影响(FOCUS)。

背景:小型试验的结果表明,氟西汀可改善卒中后的功能结局。FOCUS试验旨在提供这些影响的精确估计。

方法:FOCUS是一项实效性、多中心、平行组、双盲、随机、安慰剂对照试验,在英国103家医院进行。患者入组标准为,18岁或以上,具有临床卒中诊断,在发病后的第2天~15天入组并随机分组,具有局灶性神经功能缺损。通过使用了最小化算法的基于网络的系统,将患者随机分配到氟西汀20mg、口服、每天一次组或配对的安慰剂组,为期6个月。首要结局为功能状态,通过6个月时的改良Rankin量表(mRS)测量。治疗分组对患者、照护者、医务人员和试验团队都设盲。随机分组后的6和12个月评估功能状态。根据各自的治疗分组分析患者。试验在ISRCTN registry注册,编号ISRCTN83290762。

结果:2012年9月10日~2017年3月31日,3127名患者入组:氟西汀组1564人,安慰剂组1563人。6个月时,每组有1553人(99.3%)的mRS数据可用。氟西汀组和安慰剂组6个月时各mRS分类的分布相似(调整了最小化变量的常见比值比[OR]为0.951;95% CI,0.839~1.079;p=0.439)。氟西汀组患者6个月时发生抑郁的可能性低于安慰剂组(210人[13.43%] vs 269人[17.21%];差异,3.78%;95% CI,1.26~6.30;p=0.0033),但氟西汀组更多发生骨折(45[2.88%] vs 23[1.47%];差异,1.41%;95% CI,0.38~2.43;p=0.0070)。6或12个月时任何其他事件无显着差异。

结论:急性卒中后每天口服氟西汀20mg为期6个月不会改善功能结局。虽然治疗会减少抑郁的发生,但是会增加骨折频率。这些结果不支持常规使用氟西汀进行卒中后抑郁的预防或促进功能恢复。
