NEJM:Eculizumab治疗孕妇PNH

Eculizumab可用于治疗阵发性睡眠性血红蛋白尿症(PNH),通用名为人源型抗C5单克隆抗体。Eculizumab结合至单克隆抗体以高亲和力特异性结合至补体蛋白C5,因此抑制其裂解至C5a和C5b和防止终端补体复合物C5b-9的生成。在PNH患者中可抑制终端补体介导的血管内溶血。已有研究证实Eculizumab可以预防PNH并发症的出现,改善患者生活质量和整体生存率。但是目前关于该药物在“妊娠

Eculizumab可用于治疗阵发性睡眠性血红蛋白尿症(PNH),通用名为人源型抗C5单克隆抗体。Eculizumab结合至单克隆抗体以高亲和力特异性结合至补体蛋白C5,因此抑制其裂解至C5a和C5b和防止终端补体复合物C5b-9的生成。在PNH患者中可抑制终端补体介导的血管内溶血。已有研究证实Eculizumab可以预防PNH并发症的出现,改善患者生活质量和整体生存率。但是目前关于该药物在“妊娠期”的使用数据是很稀少的。因此Richard J等人就该方面进行了调查研究。

研究者通过问卷形式收集PNH女性妊娠期及产褥期情况,根据其后代生长发育情况以及孕产妇不良反应事件对Eculizumab的安全性和有效性进行评估。研究者共寄出94份问卷,收回75份,回复率为80%。61名PNH女性提供了75次妊娠期的相关数据。

结果显示,参与调查的孕产妇死亡率为0,不过有3名胎儿死亡案例(4%),有6次(8%)孕早期流产的案例。PNH女性在孕期输注红细胞的需求增加,怀孕前6个月输注红细胞的需求平均为0.14U/月,而妊娠期该数值达到了0.92U/月。调查的孕妇中有16次妊娠过程中输注了血小板。54%的妊娠孕早期之后PNH病情加重,使用Eculizumab的剂量和次数增加。有88%的妊娠过程中使用了低分子量肝素。出现了10例出血和2例血栓形成不良事件,并且这2例血栓形成均是在产后即产褥期发生的。妊娠中有22例(29%)早产儿。对20例新生儿采集了脐带血进行了Eculizumab药物检测,其中7例脐带血中检测到该药物。哺乳期有25名新生儿母乳喂养,对其中10名进行乳汁Eculizumab药物检测,均没有检测到该药物。

研究结果表明,Eculizumab对妊娠期的PNH女性是有益的,因为调查结果显示出了高的胎儿生存率和低的孕产妇并发症率。

Lancet Neurol:Eculizumab 治疗视神经脊髓炎谱系疾病初显效

  IgG自身抗体与水通道蛋白4(AQP4)结合后激活补体被认为是视神经脊髓炎患者中枢神经系统炎症和星形胶质细胞损伤的主要决定因素。一项来自美国的试点研究表明,Eculizumab似乎耐受良好,可以显著降低发作频率,并稳定或改善侵袭性视神经脊髓炎谱系疾病患者的神经失能指标。Eculizumab具有明显疗效,值得进一步进行更大型的随机对照研究。相关论文于2013年4月26日在线发表于《柳叶刀?&nb
