瑞典炎症性肠病 (IBD) 开始队列是为了找到诊断生物签名而建立的. 早期发现显示了蛋白质特征,自身抗体和便标志物的潜力,用于IBD检测.
科学领域:
- 胃肠道学和免疫学
- 生物标志物发现发现
- 临床研究 临床研究
背景情况:
- 炎症性肠病 (IBD) 需要改进的诊断和预后工具.
- 目前的方法缺乏长期患者结果预测的精度.
- 瑞典IBD初始群体 (SIC-IBD) 是为了满足这一需求而创建的.
研究的目的:
- 建立SIC-IBD队列,用于识别IBD的诊断和预后生物特征.
- 为了证明队列在发现新生物标志物的潜力.
- 为了促进临床决策和了解IBD的发病因子.
主要方法:
- 在瑞典八家医院招募怀疑IBD的成年患者和对照者 (2011-2021年).
- 在基线和长达10年的随访期间收集生物样本和临床数据.
- 对便calprotectin,高灵敏度C反应蛋白,血清蛋白签名,自身抗体和便标记物的分析.
主要成果:
- 包括367名IBD患者 (克罗恩氏病,性结肠炎,IBD未分类) 和168名症状/59名健康对照.
- 在IBD患者中观察到便calprotectin和hs-CRP水平升高.
- 初步数据表明,血清蛋白签名,自身抗体和便标志物可以将IBD与对照区分开来.
- 在克罗恩氏病的37%和性结肠炎患者的24%的第一年内确定了侵袭性疾病过程.
结论:
- SIC-IBD队列是识别IBD生物特征的宝贵资源.
- 多主题数据和临床信息将支持生物标志物的开发.
- 结果提供了对IBD病变的洞察力,以及改善临床管理的潜力.

Inflammatory 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...
Inflammatory 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...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
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...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
