Oesophagite a eosinophiles: mise a jour 2011 [Eosinophilic esophagitis: update 2011].

Eosinophilic esophagitis (EoE) shows an increasing incidence and prevalence in western countries and is currently the main cause of dysphagia in adults. This disease is more prevalent in males and is frequently associated with allergies. Diagnosis is based on the presence of esophageal symptoms, dense eosinophilic esophageal infiltration, and the exclusion of other conditions associated with esophageal eosinophilia. Topical corticosteroids lead to a rapid clinical and histological improvement of active EoE. Especially in children, elimination diets can have similar efficacy as topical corticosteroids. Esophageal dilation of EoE-induced strictures can also be effective in improving symptoms, but this therapy has no effect on the underlying inflammation. Long-term therapeutic strategies have yet to be defined.
