概括
研究人员确定了用于诊断eosinophilic食道炎 (EOE) 的新生物标志物. 一组生物标志物和症状有效地区分了活跃的EoE,缓解和健康的个体,提供了一种不那么侵入性的诊断方法.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 儿科胃肠病学 儿科胃肠病学
- 生物标志物发现发现
背景情况:
- 性食道炎 (EOE) 缺乏非侵入性诊断和监测生物标志物.
- 目前对EoE的诊断方法可能是侵入性的.
- 需要可靠的生物标志物来评估儿童的EoE状态.
研究的目的:
- 评估20种血清和唾液生物标志物的诊断潜力,用于儿科EOE患者.
- 确定能够区分活跃的EoE,缓解中的EoE和健康对照的生物标志物小组.
- 评估生物标志物在监测疾病进展和缓解方面的有用性.
主要方法:
- 血清和唾液生物标志物的分析,包括绝对乙氨基酸计数 (AEC),乙氨基酸衍生神经毒素 (EDN),特定IgE (sIgE) 和IgG4 (sIgG4) 抗体.
- 对15-基酸酸 (15(S) -HETE) 的评价.
- 在一小部分患者中进行纵向评估,以跟踪疾病过程中的生物标志物变化.
主要成果:
- 与健康个体相比,在活跃的EOE中观察到AEC,EDN,15(S) -HETE,sIgG4和sIgE的水平升高.
- 生物标志物 (AEC,EDN,sIgE到蛋白和小麦) 和症状的组合实现了0.92的AUC,用于区分活跃的EoE,缓解和健康组.
- 生物标志物小组在区分EoE (活性和缓解) 与健康个体方面表现出88%的灵敏度和100%的特异性.
结论:
- 一个新的生物标志物小组,结合症状,有效地区分活跃的EoE,缓解中的EoE和健康状态.
- 这些发现支持开发少入侵的诊断方法,用于儿科EoE.
- 鉴定到的生物标志物显示出作为监测小儿EoE患者的监测工具的潜力.

131
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

01:21Barrett Esophagus-I: Introduction
78
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...
