摘要
Eosinophilic esophagitis(EoE)is a chronic eosinophil inflammation that seems to be T helper type 2 antigen-driven.The disease is one of several eosinophilic gastrointestinal disorders in which there appears to be inflammation of the gastrointestinal tract without any apparent underlying causes.Differential diagnosis needs to be made with gastroesophageal reflux,which is characterized by chronic inflammation due to gastric refluxate from disorders related to motility.EoE,however,is considered a chronic allergic inflammatory disorder related to destructive tissue remodeling.There seems to be a higher prevalence of EoE in Western countries.It is typically found in atopic male individuals.Physiopathological risk factors include atopy,environmental factors,esophageal epithelial barrier dysfunctions,etc.EoE can cause several symptoms that include retrosternal burning sensation,dysphagia,food impaction,chronic reflux symptoms,nausea,and vomiting.Early diagnosis,which requires a biopsy to assess for esophageal inflammation,is essential for proper treatment.The aim of our brief overview is to summarize the current literature regarding the characteristics,diagnosis,complications,mechanisms of pathology,clinical features,influence of comorbidities,and treatment in patients with EoE.
