IBD: 克罗恩病维持治疗期间阿达木单抗药物水平升高与生物学缓解相关

2019-05-07 不详 MedSci原创

阿达木单抗是克罗恩病的有效治疗药物。有关阿达木单抗药物水平与肠道炎症的血清/粪便标志物之间关系还不清楚。因此,本项研究的目的是评估阿达木单抗水平与维持治疗期间生物学缓解之间的关系。

背景
阿达木单抗是克罗恩病的有效治疗药物。有关阿达木单抗药物水平与肠道炎症的血清/粪便标志物之间关系还不清楚。因此,本项研究的目的是评估阿达木单抗水平与维持治疗期间生物学缓解之间的关系。

方法
研究人员对诱导后至少12周接受阿达木单抗治疗的克罗恩病患者进行了单中心前瞻性横断面研究。收集患者的临床活性(Harvey-Bradshaw指数)评分,C-反应蛋白(CRP),阿达木单抗药物和抗体水平以及粪便钙卫蛋白的数据。生物学缓解定义为CRP <5 mg / L且粪便钙卫蛋白<250μg/ g。使用酶联免疫吸附测定法测定阿达木单抗药物和抗体水平。

结果
本项研究共纳入152名患者,与其他患者相比,生物缓解患者的阿达木单抗水平显着升高(12.0μg/ mL vs 8.0μg/ mL,P <0.0001)。ROC曲线分析显示,用于预测生物学缓解的最佳阿达木单抗水平为8.5μg/ mL(敏感性,82.2%;特异性,55.7%;似然比,1.9)。多变量logistic回归分析显示,阿达木单抗水平>8.5μg/ mL与生物学缓解独立相关(优势比,5.27; 95%置信区间,2.43-11.44; P <0.0001)。

结论
较高的阿达木单抗水平与生物学缓解有关。并确定了>8.5μg/ mL为最佳测量水平。
