Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Oesophageal intercellular spaces are dilated in EoE patients compared to healthy subjects. - Mucosal permeability to small molecules is increased in EoE patients compared to healthy subjects. - Tissue impedance measurement is affected in EoE patients compared to healthy subjects. - Dilated intercellular spaces correlate with affected tissue impedance and increased mucosal permeability to small molecules in EoE patients. - Affected tissue impedance correlates with increased mucosal permeability to small molecules in EoE patients. - Numbers of oesophageal intraepithelial eosinophils are increased in EoE patients compared to healthy subjects. - Numbers of oesophageal intraepithelial mast cells are increased in EoE patients compared to healthy subjects. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Tissue impedance, dilation of intercellular spaces, increased mucosal permeability to small molecules, and numbers of oesophageal intraepithelial mast cells and eosinophils are reversible by 8 weeks administration of 40 mg esomeprazole twice daily. - The composition of inflammatory cells present in the esophageal biopsies - The number of reflux episodes | — |
