Dig Dis Sci:术后 3 个月粪便钙卫蛋白水平低可预测克罗恩病的内镜术后长期缓解

2021-12-21 MedSci原创 MedSci原创

谈到克罗恩病 对于没有学过医学的人们可能很难想到它会跟胃肠疾病联系在一起。 它是一种慢性炎性肉芽肿性疾病 多见于末端回肠和邻近结肠。

超过一半的克罗恩病 (CD) 患者在其病程中会因狭窄或穿透性并发症接受一次手术,尽管术后广泛使用免疫抑制剂和生物制剂,但术后复发 (POR) 的风险仍然很高,因为高达 75% 的患者在术后第一年内经历内镜 POR,尽管其中只有四分之一有症状。现在建议在手术后的前 6-12 个月内进行回肠镜检查,以检测内镜下 POR 并指导治疗管理。然而,结肠镜检查是一种与穿孔风险相关的相对侵入性的手术。它也是费时、昂贵且不能轻易重复的。粪便钙卫蛋白(FC)是与内窥镜肠道病变严重性强相关的生物标记物。然而,最早在手术后 3 个月测量 FC 浓度以识别具有 POR 高风险的早期 CD 患者的有用性仍然存在争议。在本研究中,本项研究旨在确定回结肠切除术后 3 个月测量的 FC 的准确性,以预测 CD 的内镜 POR,并评估最佳阈值。

 

为此,研究人员收集了 55 名接受回结肠切除术的 CD 患者,在手术后 3 个月收集样本以测量血清 CRP 和 FC。在 6-12 个月(中位数为 7 个月)内通过回结肠镜评估内窥镜 POR。生成接受者操作特征 (ROC) 曲线以评估标记的准确性、确定最佳阈值并计算灵敏度、特异性、阳性和阴性预测值。

 

研究结果显示与中位 CRP 水平相比,术后 3 个月测量的中位 FC 浓度在后来经历内镜 POR(Rutgeerts ≥ i2)的患者中显着高于在接下来的 6-12 个月内保持内镜缓解的患者(205 μg/g IQR [106–721] VS 103 μg/g IQR [60–219],p= 0.008)。FC 的 ROC 曲线下面积为 0.71。用于确定术后 3 个月内镜下缓解患者的 FC 的最佳截止值为 65μg/g(96% 的敏感性、31% 的特异性、50% 的阳性预测值和 91% 的阴性预测值)。在多变量分析中,3 个月时 FC < 65 µg/g 是与随后内镜下缓解相关的唯一因素。

 

本项研究表明手术后 3 个月测量的 FC 低于 65μg/g 是识别 CD 患者的准确标志物,这些患者将在切除术后 1 年内保持内窥镜缓解。
