IBD:粪便钙卫蛋白对于判断克罗恩病的内窥镜溃疡是否缓解非常有效

2021-06-20 MedSci原创 MedSci原创

克罗恩病 (CD) 是一种慢性、进行性和可导致肠道损伤并显着改变患者生活质量的致残性疾病。

      克罗恩病 (CD) 是一种慢性、进行性和可导致肠道损伤并显着改变患者生活质量的致残性疾病。在过去十年中,CD 的治疗靶点已经从临床缓解发展到更多肠道炎症的客观标志物改变以及预防并发症的发生。内镜下黏膜愈合主要定义为不存在内窥镜下溃疡,是迄今为止CD患者最有效的治疗终点之一。为了对这样的治疗终点进行有效监控,粪钙卫蛋白逐渐成为临床工作中最常用的判断指标。由于粪便钙卫蛋白 (Fcal) 在检测单纯回肠克罗恩病 (CD) 患者的内窥镜溃疡方面的可靠性仍有争议,因此,本项研究旨在将其性能与在结肠或回结肠位置的患者中观察到的性能进行比较。

 

      本项研究共纳入分析了 123 名 CD 患者,这些患者在1个月内进行了 Fcal 测量和回肠结肠镜检查,在此期间没有任何其他的治疗干预。接受者操作特征曲线(ROC)用于确定检测内窥镜溃疡的最佳 Fcal 阈值。敏感性、特异性以及阳性 (PPV) 和阴性预测值 (NPV) 以 95% 的置信区间表示。

 

      研究结果显示存在内镜溃疡的单纯回肠型CD患者(L1组)(P = 0.025)和回结肠型和结肠型CD患者(L2-L3组)(P < 0.001)的平均Fcal水平显着升高。使用 ROC 曲线计算后发现,Fcal >200 µg/g 是检测 L1 组内镜溃疡的最佳阈值(敏感性 = 75.0,95% CI,47.6-92.7;特异性 = 87.5,95% CI, 67.6–97.3;PPV = 80.0,95% CI,51.9–95.7;NPV = 84.0;95% CI,63.9–95.5);Fcal >250 µg/g 检测 L2-L3 组内镜溃疡的最佳阈值(敏感性 = 84.1 95% CI,69.9–93;特异性=74.4, 95% CI, 57.9–87.0; PPV = 78.7, 95% CI, 64.3–89.3, NPV = 80.6, 95% CI, 64.0–91.8)。研究人员还比较了 L1 和 L2-L3 组之间的 AUC,没有显示差异(分别为 0.89 和 0.84,P= 0.46)。

      通过本项研究证实无论 CD 位置如何,粪便钙卫蛋白对于检测内窥镜溃疡非常有效,但对于单纯回肠受累的患者需要较低的临界值。
