概括

低剂量阿司匹林的使用显着增加了用于检测晚期结直肠瘤的免疫化学便隐性血液测试 (iFOBTs) 的灵敏度. 这种使用阿司匹林的特异性略低,但在查中显著提高敏感性.

科学领域:

胃肠道学和瘤学
诊断测试性能诊断测试性能
结肠直肠癌查结肠直肠癌查

背景情况:

免疫化学便隐性血液测试 (iFOBTs) 在结直肠癌查方面表现有前途.
低剂量阿司匹林的使用普遍存在,并可能增加胃肠道出血的风险.

研究的目的:

评估低剂量阿司匹林的使用如何影响两个定量IFOBT的性能.
在接受结直肠癌查的患者中评估iFOBT准确性.

主要方法:

一项涉及德国南部1979名患者 (2005-2009) 的诊断研究.
在低剂量阿司匹林使用者和非使用者之间比较两个iFOBT的性能指标 (灵敏度,特异性,ROC曲线).
包括检测晚期结直肠瘤 (癌症或晚期腺瘤).

主要成果:

在阿司匹林使用者的10.3%和非使用者的10.4%中发现了先进的瘤.
与非使用者 (P=.001) 相比,阿司匹林使用者的iFOBT敏感性明显更高 (例如,70.8%与35.9%相比).
用户的特异性略低 (例如,85.7%与89.2%相比),ROC AUC在用户中更高,特别是男性.

结论:

低剂量阿司匹林的使用与与iFOBTs检测晚期结肠直肠瘤的显著更高的敏感性有关.
低剂量阿司匹林使用时,iFOBTs的特异性仅略有降低.
研究结果表明,阿司匹林使用会影响结肠直肠癌查中的iFOBT性能.

Serum Laboratory Studies, Stool Test, Breath Test

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...

Drugs for Treatment of Ulcerative Colitis in IBD

Drugs for Treatment of Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide generation.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

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 colonic...
