概括
便中的microRNA-223 (miR-223) 显示出作为克罗恩病 (CD) 活动的非侵入性生物标志物具有前途. 这项研究发现便中的miR-223水平准确地反映了疾病的严重程度,可能超过其他标志物.
科学领域:
- 胃肠病学和肝病学
- 分子生物学分子生物学
- 生物标志物发现发现
背景情况:
- 克罗恩氏病 (CD) 是一种慢性炎症性肠病,需要对疾病活动进行精确的监测.
- 微RNA-223 (miR-223) 已被确定为CD的潜在非侵入性生物标志物.
- 测量miR-223以评估CD活性的最佳组织来源尚不清楚.
研究的目的:
- 为了比较血清,肠道组织和CD患者和健康对照的便样本中miR-223的表达水平.
- 为了确定哪个miR-223源与CD疾病活性指数最好地相关.
- 评估CD中miR-223的诊断和预后潜力.
主要方法:
- 收集了来自CD患者和健康对照者的血清,终端质粘膜活检和便样本.
- 使用CD活动指数 (CDAI) 和CD简单内镜评分 (SES-CD) 评估CD活动.
- 在所有样本类型和与临床和炎症标志物相关的水平中量化miR-223表达.
主要成果:
- 与对照人群相比,CD患者的血清,肠道组织和便中的miR-223水平显著升高.
- 所有样本类型中的miR-223表达与CD疾病活性 (CDAI,SES-CD) 有正相关.
- 便miR-223表现出较高的特异性和可比或更高的精度 (AUC) 血清miR-223,组织miR-223,C反应蛋白和便calprotectin评估CD疾病活性.
结论:
- 在CD患者中,miR-223在血清,肠道组织和便区内显著上调.
- 便miR-223成为评估克罗恩病活动的高度特定和准确的非侵入性生物标志物.
- 便miR-223的进一步验证可能会导致改善CD患者的非侵入性监测.

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...

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...
