概括
性食道炎 (EoE) 症状与非上皮食道基因表达相关,这表明纤维细胞在这种情况下有助于症状严重程度.
科学领域:
- 胃肠道学和免疫学
- 分子生物学分子生物学
- 翻译医学是一种翻译医学.
背景情况:
- 人们还不太了解导致异性食道炎 (EOE) 引起多种症状的潜在机制.
- 患者报告的结果往往不能完全捕捉到疾病的复杂性.
研究的目的:
- 为了研究患者报告的症状严重程度和 EoE 中食道基因表达之间的关系.
- 为了确定特定的基因和细胞类型,涉及到EoE症状病原体.
主要方法:
- 分析了146名成人EoE患者的数据,将EoE活动指数 (EEsAI) 与EoE诊断面板 (EDP) 基因表达进行比较.
- 使用单细胞RNA测序来确定EEsAI相关基因的细胞起源.
- 根据食道扩张史和症状严重程度 (轻度与重度) 来分组患者.
主要成果:
- 在EEsAI和EDP总分数之间发现了显著的相关性,特别是在没有最近食道扩张的患者中.
- 14个EoE诊断组基因与EEsAI得分有显著的相关性,11个基因表达在非皮质细胞中,3个基因表达在上皮细胞中.
- 非皮质基因,特别是由纤维细胞表达的基因,在症状负担较高的患者中被上调,并且在缓解期间没有显著下降,与皮质基因不同.
结论:
- 这项研究表明,患者报告的症状与食道中非皮质基因的表达之间存在联系.
- 这些发现凸显了非皮质细胞 (如纤维细胞) 在促进患有性食道炎的个体体体验的症状严重性方面发挥的重要作用.

Barrett Esophagus-II: Clinical Manifestations and Management
139
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...
