JCC: 维多珠单抗治疗的女性IBD患者的妊娠结局分析

2018-03-19 MedSci MedSci原创

Vedolizumab(VDZ)维多珠单抗是一种肠道靶向的IgG1抗-α4β7整联蛋白,被批准用于治疗炎症性肠病(IBD)。由于IBD通常会影响育龄妇女,因此VDZ患者的妊娠结局研究非常重要。动物研究表明,MAdCAM-1(α4β7-整合素的配体)在胎盘发育期间由母体血管表达,因此巨噬细胞/单核细胞谱系的α4β7表达细胞被认为在母体/胎儿耐受中是重要的。VDZ阻止此交互可能会影响妊娠过程。

背景:Vedolizumab(VDZ)维多珠单抗是一种肠道靶向的IgG1抗-α4β7整联蛋白,被批准用于治疗炎症性肠病(IBD)。由于IBD通常会影响育龄妇女,因此VDZ患者的妊娠结局研究非常重要。动物研究表明,MAdCAM-1(α4β7-整合素的配体)在胎盘发育期间由母体血管表达,因此巨噬细胞/单核细胞谱系的α4β7表达细胞被认为在母体/胎儿耐受中是重要的。VDZ阻止此交互可能会影响妊娠过程。

方法:这项回顾性全国性观察研究评估了VDZ治疗下IBD患者怀孕的结果。研究人员收集了孕妇们疾病活动情况,产前并发症,分娩和新生儿结局的详细信息。

结果:研究人员收集了共有23次怀孕记录。有五个女性在受孕时都有疾病缓解。有18名产儿存活(72%为女性,包括两名双胞胎),两次中断妊娠和五次怀孕仍在进行中。缓解(n = 12)的患者报告了以下并发症:子宫内生长迟缓(n = 1),子痫(n = 1),膜胎膜早破(n = 2)和先天性畸形(n =2,髋关节发育不良和肺动脉瓣狭窄)。在妊娠期有活动性疾病的5名患者中,三名怀孕未受影响,其中一名女性在22周时因绒毛膜羊膜炎而失去胎儿,另一名女性由于自身问题而主动终止。一名患者在怀孕期间疾病活动爆发,并且患有先天性巨结肠症。

结论:这是VDZ治疗患者妊娠结局最大的队列研究。尽管妊娠数仍然很少,但研究人员观察到一些产前并发症和先天性畸形,这启发我们对VDZ治疗的IBD患者的警惕性和严格随访是必要的。
