Activated Duodenal Mucosal Eosinophils in Children With Dyspepsia: A Pilot Transmission Electron Microscopic Study

Abstract

Eosinophils present in the duodenal mucosa of children with dyspepsia are activated in a significant proportion of patients, even in those with normal eosinophil counts. The degree of degranulation is similar to that seen in other conditions where eosinophils have a pathogenic role.
