IBD:粪钙卫蛋白水平有望替代内镜检查判断肠道粘膜愈合情况

2020-07-16 MedSci原创 MedSci原创

粪便钙卫蛋白(FC)是溃疡性结肠炎(UC)和克罗恩病(CD)患者黏膜愈合(MH)的常见替代指标。本项研究旨在通过使用先进的内窥镜技术定义内镜缓解(ER)和组织学缓解(HR)的来确定最佳的FC阈值。

背景:

粪便钙卫蛋白(FC)是溃疡性结肠炎(UC)和克罗恩病(CD)患者黏膜愈合(MH)的常见替代指标。本项研究旨在通过使用先进的内窥镜技术定义内镜缓解(ER)和组织学缓解(HR)的来确定最佳的FC阈值。

 

方法:

在这项横断面研究中,研究人员收集了76名UC和41名CD患者的临床,内镜,组织学数据和FC。创建接收器工作特征曲线以评估FC的最佳截止值,以通过Mayo内窥镜评分(MES),溃疡性结肠炎内窥镜严重程度指数(UCEIS)和改良的PICaSSO(帕丁顿国际虚拟染色体内窥镜评分)评估粘膜愈合情况。

 

结果

在UC患者中,用MES,UCEIS和改良的PICaSSO计算得出的用于识别ER的FC的最佳阈值分别为112、148和161 mcg/g,准确度分别为86.9%,86.8%和81.6%。在CD患者中,预测ER的最佳FC截止值为96 mcg/g,准确度为82.9%。

 

结论

FC值阈值介于112 mcg / g和172 mcg / g之间可确定UC患者的ER和HR,而CD患者应考虑225 mcg / g以下的值。
