Special Issue Information

Dear Colleagues,

Eosinophilic gastrointestinal disorders are a group of disorders characterized by the pathologic eosinophilic infiltration of various organs of the gastrointestinal tract, the esophagus, stomach, small intestine, and the colon. Pathological eosinophilic infiltration may cause symptoms such as dysphagia, food impaction, dyspepsia, abdominal pain, diarrhea, heartburn, abdominal pain, and vomiting in children. These disorders are considered immune-mediated chronic inflammatory disorders with strong links to food allergen triggers. Recent years have witnessed significant advances in basic science research, clinical diagnosis, and the management of eosinophilic gastrointestinal disorders. Treatment strategies focus on either medical or dietary therapy. The main aim of this Special Issue is to shed light on the clinical presentation, pathophysiology, diagnosis, and treatment of these increasingly recognized disorders.

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated inflammatory condition of the esophagus characterized by eosinophilic infiltration, and hallmark symptoms of esophageal dysfunction such as dysphagia and food impaction. Over the past three decades, EoE has been recognized as a distinct clinical entity, distinguished from gastroesophageal reflux disease (GERD) through advancements in diagnostic techniques, particularly endoscopy with biopsy. The rising global prevalence of EoE reflects enhanced diagnostic awareness, evolving criteria, and environmental along with lifestyle changes. The etiology of EoE is multifactorial, involving genetic predispositions, immune dysregulation, the gut microbiome, and environmental triggers, including dietary allergens and aeroallergens. Key mechanisms include a type 2 helper T-cell (Th2)-driven immune response, epithelial barrier dysfunction, and genetic variants such as CAPN14 and TSLP. Chronic inflammation leads to tissue remodeling, fibrosis, and esophageal narrowing, contributing to disease progression and complications. Management strategies have evolved to include dietary elimination, proton pump inhibitors, topical corticosteroids, biologics, and endoscopic interventions for fibrostenotic complications. Emerging therapies targeting cytokines such as interleukin (IL)-4, IL-5, and IL-13, alongside novel diagnostic tools like the esophageal string test and Cytosponge, offer promising avenues for improved disease control and non-invasive monitoring. Long-term surveillance combining endoscopic and histological evaluations with biomarkers and non-invasive tools is critical to optimizing outcomes and preventing complications. Future research should address gaps in understanding the role of the esophageal microbiome, refine therapeutic approaches, and develop personalized strategies to improve disease management and patient quality of life.
