Abstract:
Eosinophilic gastrointestinal diseases are a group of diseases with repeated or persistent gastrointestinal symptoms and the increase of eosinophils in gastrointestinal mucosa.Pathology shows an increase in the number of eosinophils in gastrointestinal mucosa.Fibrosis can be seen in the lamina propria of esophageal mucosa in patients with eosinophilic esophagitis.A variety of cytokines may be chemotactic to the aggregation of eosinophils, including Th2 cytokines, eotaxin, thymic stromal lymphopoietin, macrophage migration inhibitory factor, sialic acid-binding immunoglobulin-like lectin, integrin and extracellular matrix protein.The intestinal tissue injury of eosinophilic gastrointestinal diseases may be related to eosinophil degranulation and secretion of specific products, inflammatory response, oxidative damage, fibrosis, tissue remodeling and impaired barrier function.
