便中的calprotectin (FC),interleukin-8 (IL-8) 和红细胞沉率 (ESR) 显示出诊断炎症性肠病 (IBD) 的最高有效性. 与其他生物标志物一起,这些生物标志物在IBD患者中与健康对照人群相比显著升高.
科学领域:
- 胃肠道学和免疫学
- 生物标志物发现发现
- 炎症性肠病 (IBD) 研究研究
背景情况:
- 全球炎症性肠道疾病 (IBD) 发病率不断上升.
- 病因不明,但最近在了解IBD发展方面取得了重大进展.
- 需要可靠的IBD诊断标记物.
研究的目的:
- 评估IBD炎症生物标志物的诊断意义.
- 评估这些生物标志物与疾病活动的关联.
- 使用生物标志物将IBD患者与健康对照区分开来.
主要方法:
- 病例控制研究68名IBD患者 (34名克罗恩氏病,34名性结肠炎) 和52名健康对照.
- 测量便calprotectin (FC),C反应蛋白 (CRP),红细胞沉积率 (ESR) 和各种间白蛋白 (IL),包括IL-6,IL-17A,IL-8和IL-1β.
- 分析完整血细胞计数,包括中性粒细胞-淋巴细胞比率 (NLR) 和红细胞指数.
主要成果:
- 与对照组相比,IBD患者的ESR,CRP,FC,所有IL,中性粒细胞,NLR和血小板水平显著更高.
- 在IBD患者中显著降低淋巴细胞 (%),淋巴细胞-中型白细胞比率 (LMR),血红蛋白,平均体质血红蛋白 (MCH),血红素和红细胞分布宽度 (RDW).
- 接收器操作特征 (ROC) 曲线分析确定了FC,IL-8和ESR作为IBD诊断中最有效的生物标志物.
结论:
- 所有研究的插白蛋白在IBD患者中都升高,克罗恩病和性结肠炎之间没有显著差异.
- 便中的calprotectin (FC),IL-8和ESR显示出对IBD的诊断有效性最高.
- 研究的参数被验证为炎症性肠道疾病的潜在生物标志物.

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...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
