Eosinophilic esophagitis (EoE) is an immune-mediated disorder characterized by esophageal inflammation and related structural changes causing symptoms such as feeding difficulties and food impaction. The pathophysiological mechanisms underlying EoE remain poorly understood. Preclinical studies using mouse models have been critical in comprehending human disease mechanisms and associated pathways. In this chapter, we describe an experimental method using a noninvasive label-free optical imaging technique, optical coherence tomography, to characterize the pathophysiological changes in the esophagus of mice with EoE-like disease ex vivo.

Article Synopsis
  • Eosinophilic esophagitis (EoE) is a chronic immune disease characterized by symptoms of esophageal dysfunction and an eosinophil-dominated infiltration in the esophagus.
  • The incidence of EoE is rising, requiring attention in various medical settings, leading to updated guidelines that focus on improved diagnosis and treatment strategies.
  • Recommended treatments include proton pump inhibitors, topical steroids, dietary elimination, and esophageal dilation, with an emphasis on monitoring patients for treatment response and managing both inflammatory and structural aspects of the disease.

Article Synopsis
  • Eosinophilic esophagitis (EoE) is a chronic condition caused by eosinophilic inflammation in the esophagus, mainly triggered by food and air allergens.
  • A 4-year-old boy diagnosed with EoE showed improvement with topical steroids, and by age 7, he also developed a grass pollen allergy.
  • Significant increases in eosinophil counts and pediatric symptom scores were noted from winter to spring, suggesting that environmental allergens may play a role in EoE, which could influence treatment timing and strategies during allergy seasons.

Similarly to acute intestinal helminth infection, several conditions of chronic eosinophilic type 2 inflammation of mucosal surfaces, including asthma and eosinophilic esophagitis, feature robust expansions of intraepithelial mast cells (MCs). Also the hyperplastic mucosa of nasal polyposis in the context of chronic rhinosinusitis, with or without COX1 inhibitor intolerance, contains impressive numbers of intraepithelial MCs.
