BACKGROUND Endoscopy, standard-of-care for monitoring Eosinophilic Esophagitis (EoE), assesses mucosal inflammation. The Esophageal String Test (EST®), a minimally invasive swallowed capsule and immunoassays, quantifies EoE inflammation. We determined whether the EST/EoEScore can monitor disease in patients undergoing treatment. METHODS Thirty-three samples from 14 EoE patients (7 children, 7 adults) who underwent repeat endoscopies and ESTs were studied. Biopsies were analyzed for peak eosinophil counts; ESTs analyzed for EoEScores. RESULTS Eosinophil counts and EoEScores significantly correlated during treatment, distinguishing patients with active EoE from treatment-associated remissions for 93.9% of ESTs performed. CONCLUSION The EST can be used to longitudinally monitor responses to treatment in EoE.

微创 1 小时食管串试验 (EST) 监测嗜酸性粒细胞性食管炎粘膜炎症的治疗变化。



背景 内窥镜检查是监测嗜酸性粒细胞性食管炎 (EoE) 的标准护理,可评估粘膜炎症。食管线测试 (EST®) 是一种微创吞咽胶囊和免疫测定法,可量化 EoO 炎症。我们确定了 EST/EoEScore 是否可以监测接受治疗的患者的疾病。方法 研究了 14 例接受重复内窥镜检查和 EST 的 EoE 患者 (7 例儿童,7 例成人) 的 33 个样本。分析活检的嗜酸性粒细胞峰值计数;分析 EoEScore 的 EST。结果 嗜酸性粒细胞计数和 EoEScores 在治疗过程中显著相关,区分了 93.9% 的 EST 活动性 EoO 患者与治疗相关缓解患者。结论 EST 可用于纵向监测 EoE 对治疗的反应。
