Eosinophilic esophagitis (EoE) is an increasingly diagnosed, immune-mediated disease characterized by inflammation of the esophagus in both children and adult, causing significant morbidity. Adults typically present with dysphagia and a history of food impaction. Diagnosis should be considered in patients with histological evidence of eosinophilia (≥15 eosinophils per high-power field) on esophageal biopsy. More recently, it has been observed that a significant percentage of patients with esophageal eosinophilia respond both clinically and histologically to PPI therapy. This disorder has been named PPI-responsive esophageal eosinophilia (PPI-REE). Recent studies suggest that patients with PPI-REE have similar clinical and endoscopic features of patients with EoE. Specifically, both PPI-REE and EoE patients have a strong disposition to allergy compared to patients without eosinophilia. As such, PPI-REE may represent a subset or variant of EoE. Effective treatment of EoE requires a multidisciplinary approach with gastroenterologists, pathologists, allergists, and nutritionists. Treatments include elimination and elemental diets, topical glucocorticoids (fluticasone and budesonide), and endoscopic dilation.
嗜酸性粒细胞性食管炎(EoE)是一种诊断率日益增高的免疫介导性疾病,其特征为儿童和成人食管均发生炎症,可导致严重发病。成人通常表现为吞咽困难及食物嵌塞史。食管活检有嗜酸性粒细胞增多(每高倍视野≥15个嗜酸性粒细胞)组织学证据的患者应考虑诊断。最近,有人观察到相当比例的食管嗜酸性粒细胞增多患者对质子泵抑制剂(PPI)治疗在临床和组织学上均有反应。这种病症被命名为PPI反应性食管嗜酸性粒细胞增多症(PPI-REE)。最近的研究表明,PPI-REE患者具有与EoE患者相似的临床和内镜特征。具体而言,与无嗜酸性粒细胞增多的患者相比,PPI-REE和EoE患者均有较强的过敏倾向。因此,PPI-REE可能代表EoE的一个亚型或变异型。EoE的有效治疗需要胃肠病学家、病理学家、过敏症专科医生和营养学家采取多学科方法。治疗方法包括排除饮食和要素饮食、局部糖皮质激素(氟替卡松和布地奈德)以及内镜扩张。
