IBD: 回肠末端厚度是克罗恩病患者行英夫利昔单抗治疗结果的预测指标

2020-09-16 MedSci原创 MedSci原创

较高的英夫利昔单抗谷水平与CD的良好预后相关,而较低的英夫利昔单抗谷水平与疾病恶化和对英夫利昔单抗(IFX)治疗的反应丧失有关

         我们都知道,较高的英夫利昔单抗谷水平与CD的良好预后相关,而较低的英夫利昔单抗谷水平与疾病恶化和对英夫利昔单抗(IFX)治疗的反应丧失相关。此外,透壁愈合(肠壁厚度[BWT]减小到≤3 mm)是一个重要的治疗目标,即使在停止生物治疗后,其也能改善所有临床结果和更好的长期效果。肠道超声检查(IUS)是一种非侵入性检查,目前已广泛用于评估克罗恩病(CD)疾病活动情况。因此,本项研究旨在对维持治疗期间通过IUS进行的末端回肠(TI)厚度测量与治疗失败的可能性之间的关系进行分析。

 

        研究人员对2016年1月至2019年3月间在谢巴医学中心接受常规IFX治疗的CD患者进行了IFX谷水平和抗IFX抗体水平的评估。接受定期IFX维持治疗并在治疗的第14周后接受至少1次IUS检查的成年CD患者被纳入本项研究,主要观察目标是维持期TI厚度与CD的后续临床结局之间的关系。

 

 

           最后共有60例接受IFX治疗的CD患者被纳入研究。肠指数超声检查后,对患者进行了中位16个月(5-24个月)的随访。38例患者(63.3%)治疗的有长期维持反应,22例患者(36.6%)治疗失败,平均随访时间分别为10.5个月(6.5-17个月)和9.25个月(1-10.25个月)。在单变量分析中,治疗反应和失败之间唯一不同的变量是TI厚度,(2.8 vs. 5 mm,P <0.0001)和IFX谷水平(6.6 vs. 3.9 µg / mLP = 0.008)。在多变量分析中,只有小肠厚度≥4mm与治疗失败的风险有关(OR,2.9; 95%CI,1.49-5.55;P = 0.002)。

 

          最后,研究人员说道:肠壁厚度与克罗恩病患者对于英夫利西单抗的治疗效果有明显的预测作用,透壁厚度≥4mm可以预测使用IFX治疗的CD患者的治疗失败。
