儿童早期发病的炎症性肠病 (VEO-IBD) 与晚期发病的IBD相比,具有明显的内镜和组织学特征. VEO-IBD显示了不同的疾病局部化和性结肠炎的较低组织学负担.
科学领域:
- 儿科胃肠病学 儿科胃肠病学
- 炎症性肠道疾病研究研究
- 组织病理学 组织病理学
背景情况:
- 炎症性肠病 (IBD) 包括慢性胃肠道炎症.
- 非常早发性IBD (VEO-IBD) 在6岁之前出现,与晚发性IBD (LO-IBD) 不同.
- 了解VEO-IBD的独特特征对于诊断和管理至关重要.
研究的目的:
- 为了比较VEO-IBD的内镜和组织学特征与儿童的LO-IBD.
- 为了确定VEO-IBD和LO-IBD之间疾病局部化和组织发现的独特模式.
主要方法:
- 在两个意大利儿科IBD转诊中心进行了一项多中心的回顾性观察研究.
- 患有VEO-IBD的患者与1:1的性结肠炎 (UC) 和1:2的克罗恩病 (CD) 与LO-IBD对照匹配.
- 临床,内镜和组织学数据被追溯收集和分析.
主要成果:
- 分析了53名VEO-IBD患者和68名LO-IBD患者.
- 维奥-克罗恩病 (CD) 更频繁地与孤立的结肠病 (p=0.002) 相结合.
- VEO-性结肠炎 (UC) 显示了更频繁的全结肠参与 (p=0.05),但与LO-UC相比,组织学负担较低 (例如,较少的基底血细胞,杯状细胞枯竭).
- 跳过病变在LO-CD中比VEO-CD更常见 (p=0.031).
结论:
- VEO-IBD和LO-IBD在疾病程度和组织学特征方面表现出不同的表型.
- 与LO-UC患者相比,患有VEO-IBD的儿科UC患者的组织学负担减少.
- 典型的CD组织学特征在VEO-CD患者中较少观察到.

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...
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...
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...
Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
