概括
对环境肠道功能障碍 (EED) 验证的生物标志物显示与十二指肠组织学有关. 便标志物和乳糖糖 (LR) 测试显示有希望,但1小时的尿液收集可能不足以进行LR测试.
科学领域:
- 儿科胃肠病学 儿科胃肠病学
- 生物标志物发现发现
- 肠道功能障碍研究 研究 肠道功能障碍研究
背景情况:
- 环境肠道功能障碍 (EED) 研究需要验证的生物标志物.
- 目前对EED病原学的理解受到缺乏可靠标记物的限制.
研究的目的:
- 调查EED儿童中常用的生物标志物和十二指肠组织学之间的关联.
- 为了评估1小时和2小时尿液收集对乳糖糖 (LR) 测试在评估小肠透性的实用性.
主要方法:
- 一个涉及EED的营养不良儿童的多国分析.
- 十二指肠活检分析了他的病理学,并与便calprotectin (CAL),骨髓氧化酶 (MPO),新素 (NEO) 和尿液LR测试结果进行了比较.
- 使用多变量回归模型来评估生物标志物协会,并根据相关的共变量进行调整.
主要成果:
- 便CAL与内皮细胞淋巴细胞有关.
- 便中的MPO和NEO与内布鲁纳腺有关.
- 便NEO与慢性炎症有关,乳糖恢复与内皮细胞淋巴细胞有关.
- 与2小时收集相比,1小时收集尿液时,乳糖米的回收明显较低.
结论:
- 四种常用的生物标志物与EED的特定组织学特征有相关性.
- 采集1小时的尿液可能无法充分捕捉小肠透性,使用LR测试.
- 这些发现支持对EED生物标志物的进一步验证,尽管在组织获取方面存在挑战.

Anatomy of the Intestines
71.6K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
323
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...
