Eosinophilic esophagitis (EoE) in adults in Icelandic and international context

Eosinophilic esophagitis (EoE) is a common cause of swallowing difficulties in both children and adults. The incidence of EoE has been increasing over the past decades, which cannot be solely attributed to improved diagnostic techniques. EoE is more common in adults than in children. The diagnosis is confirmed by a biopsy from the esophageal mucosa showing a significant infiltration of eosinophils. Many patients respond to treatment with proton pump inhibitors, but those with severe EoE may require dietary modifications, topical steroids, and/or dilation of esophageal strictures. This review covers the incidence, risk factors, natural course, diagnosis, and treatment options for EoE, both within the Icelandic healthcare system andi n a broader context.
