The epithelium is integral to the protection of many different biological systems and for the maintenance of biochemical homeostasis. Emerging evidence suggests that particular children have epithelial vulnerabilities leading to dysregulated barrier function and integrity, that resultantly contributes to disease pathogenesis. These epithelial vulnerabilities likely develop in utero or in early life due to various genetic, epigenetic and environmental factors. Although various epithelia are uniquely structured with specific function, prevalent allergic-type epithelial diseases in children potentially have common or parallel disease processes. These include inflammation and immune response dysregulation stemming from atypical epithelial barrier function and integrity. Two diseases where aetiology and pathogenesis are potentially linked to epithelial vulnerabilities include Paediatric Asthma and Eosinophilic Oesophagitis (EoE). For example, rhinovirus C (RV-C) is a known risk factor for paediatric asthma development and is known to disrupt respiratory epithelial barrier function causing acute inflammation. In addition, EoE, a prevalent atopic condition of the oesophageal epithelium, is characterised by similar innate immune and epithelial responses to viral injury. This review examines the current literature and identifies the gaps in the field defining viral-induced effects on a vulnerable respiratory epithelium and resulting chronic inflammation, drawing from knowledge generated in acute wheezing illness, paediatric asthma and EoE. Besides highlighting the importance of epithelial structure and barrier function in allergic disease pathogenesis regardless of specific epithelial sub-types, this review focuses on the importance of examining other parallel allergic-type disease processes that may uncover commonalities driving disease pathogenesis. This in turn may be beneficial in the development of common therapeutics for current clinical management and disease prevention in the future.

We want to present a case of eosinophilic esophagitis (EoE) after a herpetic esophagitis (HE) to increase the available evidence on the association suggested between both entities recently published by Iriarte Rodríguez et al.

Gastroenterologists frequently perform endoscopic esophageal mucosal biopsies for pathologic diagnosis in patients experiencing symptoms of esophagitis. The more common causes of esophagitis diagnosed on esophageal mucosal biopsy include reflux esophagitis, eosinophilic esophagitis, and infectious esophagitis caused by Candida albicans, herpes simplex virus, and/or cytomegalovirus. However, there are several causes of esophagitis seen less frequently by pathologists that are very important to recognize. We discuss unique types of esophageal inflammation, including acute bacterial esophagitis, esophageal manifestations of dermatologic diseases, medication-induced esophageal injury, and sloughing esophagitis; and we review their clinical and histopathologic features.
