DSS: 维持性阿达木单抗浓度可以使炎症性肠病长期处于缓解期

2018-11-19 MedSci MedSci原创

生物制剂疗法正在成为治疗炎症性肠病(IBD)[克罗恩病(CD)和溃疡性结肠炎(UC)]的新标准治疗方法。因此,本项研究旨在探究维持治疗期间血清阿达木单抗浓度与IBD生化,内镜和组织学缓解的关系。

背景
生物制剂疗法正在成为治疗炎症性肠病(IBD)[克罗恩病(CD)和溃疡性结肠炎(UC)]的新标准治疗方法。因此,本项研究旨在探究维持治疗期间血清阿达木单抗浓度与IBD生化,内镜和组织学缓解的关系。

方法
这是一项回顾性多中心研究,纳入的是使用阿达木单抗作为维持治疗的IBD患者,他们在接受治疗1周内接受C反应蛋白(CRP)检测和/或12周内进行内镜评估。生化缓解定义为CRP≤5mg / L。内镜下缓解被定义为对于CD的回结肠Rutgeerts评分≤i1或UC的Mayo内窥镜评分≤1。组织学缓解定义为没有任何活动性炎症迹象。

结果
共有98名IBD患者的接受本项试验,基于ROC曲线分析,研究人员确定了生化,内镜或组织学缓解的阈值,CD中阿达木单抗浓度阈值分别为11.8,12和12.2μg/ mL,UC中分别为10.5,16.2和16.2μg/ mL。阿达木单抗浓度≥12μg/ mL(OR 8; 95%CI 2-31.9;p= 0.003)和≥12.2μg/ mL(OR 9.6; 95%CI 1.7-56.1;p= 0.012)与CD中的内镜和组织学缓解独立相关。

结论
该研究表明,较高维持浓度的阿达木单抗与IBD的良好治疗结果相关。
