Eosinophilic gastroenteritis.
Eosinophilic gastroenteritis is an infrequently diagnosed condition that is characterized by prominent eosinophilic infiltration of the stomach or small intestine, generally localized to one level of the intestinal wall; the variable organ locus and wall depth produce heterogeneous clinical presentations. A strong association with atopy is present in most cases, supported by circumstantial evidence and the demonstration of Th-2 proinflammatory cytokine profiles in animal studies. A high degree of suspicion is required to establish the diagnosis, which must be based on intense gastrointestinal eosinophilia. Management is directed toward removal of offending allergens and use of anti-inflammatory agents. Novel and emerging treatments on the horizon are biologic therapies and selective anti-eosinophil agents.
