Eosinophilic oesophagitis (EO) - also abbreviated to EoE in American publications - is a disease characterised by oesophageal symptoms and infiltration of eosinophils in the oesophageal epithelium. Originally thought to be a type of gastro-oesophageal reflux disease (GORD), its failure in many (but not all) patients to respond to proton pump inhibitors (PPIs) and the recognition of eosinophilic infiltration on biopsy eventually led to EO being classified as a disease in its own right.
