概括
一个新的数字图像分析工具FibroNestTM准确地量化了炎症性肠道疾病 (IBD) 中的纤维化. 这种方法使克罗恩氏病 (CD) 与纤维化不同于其他IBD类型,有助于诊断和治疗策略.
科学领域:
- 胃肠病学
- 数字病理学
- 计算生物学
背景情况:
- 纤维化是炎症性肠道疾病 (IBD),特别是克罗恩病 (CD) 的关键特征,显著影响患者的发病率.
- 目前在IBD中的组织纤维化评估缺乏标准化和可重复性,阻碍了准确的临床评估.
- 肠壁不同层的纤维化分布不同, 复杂化了分析.
研究的目的:
- 开发和验证一个定量数字图像分析平台,用于标准化和可重复的IBD肠道纤维化评估.
- 产生持续性纤维化严重性得分和子得分,反映不同的组织表型和肠壁层.
- 区分各种IBD亚型,包括带有纤维化或没有纤维化的克罗恩病和性结肠炎 (UC).
主要方法:
- 将FibroNestTM数字图像分析平台应用于IBD切除样本的Masson三色染色全片图像.
- 总体纤维化严重性的定量评估和基于不同纤维化表型的四个分数的计算.
- 开发一种适用于内镜活检的粘膜纤维化评估方案.
主要成果:
- 通过FibroNestTM得分,克罗恩病与纤维化结肠炎明显区别于没有纤维化结肠炎的克罗恩病.
- 克罗恩病没有纤维化表现出UC和克罗恩病与纤维化之间的中间纤维化得分.
- 在粘膜纤维化方案中,克罗恩病与无纤维化的粘膜纤维化特征存在显著差异.
结论:
- FibroNestTM平台提供了一种可复制的IBD纤维化量化方法,有助于疾病分类.
- 开发的评分系统有效地区分了与IBD相关的不同纤维化模式和疾病状态.
- 一个新的粘膜纤维化评估方案可以在克罗恩病患者的基础纤维化早期检测,可能在手术切除之前.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
