J Gastroenterology: 患有症状性小肠狭窄克罗恩病的疾病进展研究

2020-02-06 不详 网络

小肠狭窄是克罗恩病(CD)患者最常见的并发症之一。内窥镜球囊扩张术(EBD)是一种微创治疗方法,可以最大程度避免手术。但是,EBD是否能阻止后续手术尚不清楚。本项研究旨在探究导致小肠狭窄患者手术的因素以及与初次EBD后的后续导致手术相关的因素。

背景
小肠狭窄是克罗恩病(CD)患者最常见的并发症之一。内窥镜球囊扩张术(EBD)是一种微创治疗方法,可以最大程度避免手术。但是,EBD是否能阻止后续手术尚不清楚。本项研究旨在探究导致小肠狭窄患者手术的因素以及与初次EBD后的后续导致手术相关的因素。

方法
研究人员回顾性收集2008年之后出现小肠狭窄症状的未经手术治疗的CD患者的数据,以及当时他们开始使用球囊辅助肠镜检查和抗肿瘤坏死因子(TNF)维持治疗。

结果
总共有32个三级转诊中心的305例病例入选。1年累积无手术生存率为74.0%,5年累积为54.4%,10年累积为44.3%。与避免手术相关的因素有:疾病发作不剧烈,发病率不高,症状轻度,成功的EBD,狭窄长度<2 cm,以及阻塞症状发作后添加了免疫调节剂或抗TNF。在初始成功的EBD成功的95例中,更长的EBD间隔与较低的手术风险相关。接受者的操作特征分析显示,EBD间隔≤446天可预测随后的手术,并且在需要频繁扩张的患者中,吸烟者的比例明显较高。

结论
在有症状的小肠狭窄的CD患者中,通过避免频繁的EBD和初次EBD后的后续手术,增加免疫调节剂或抗TNF和戒烟可以改善有症状的小肠狭窄的预后。

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。
