About this study

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EoG, EoN and EoC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.
