Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
EoE group
Patients with confirmed eosinophilic esophagitis
|
Esophageal mucosal biopsies are collected during gastroscopy
Blood will be drawn by venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing vacutainer tubes and into serum tubes
|
GERD group
Patients with gastro-esophageal reflux disease
|
Esophageal mucosal biopsies are collected during gastroscopy
Blood will be drawn by venipuncture into citrate- or ethylenediaminetetraacetic acid (EDTA)-containing vacutainer tubes and into serum tubes
|
Control group
Individuals with no esophageal disease
|

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Analysis of cannabinoid receptors- protein content
Time Frame: within 48 months
|
Cannabinoid receptors (protein) are measured by flow cytometry in blood leukocytes of patients with EoE (acute and in remission), and of control individuals.
|
within 48 months
|
Analysis of cannabinoid receptors- transcripts
Time Frame: within 48 months
|
Transcripts of cannabinoid receptors are measured in esophageal mucosal biopsies of patients with EoE (acute and in remission), GERD and in control individuals by polymerase chain reaction.
|
within 48 months
|
Analysis of prostaglandin D2 receptors- protein content
Time Frame: within 48 months
|
Prostaglandin D2 receptors (protein) are measured by flow cytometry in blood leukocytes of patients with EoE (acute and in remission), and of control individuals.
|
within 48 months
|
Analysis of prostaglandin D2 receptors - transcripts
Time Frame: within 48 months
|

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Endoscopic Reference Score
Time Frame: within 48 months
|
Assessment of an Endoscopic Reference Score: Endoscopic findings will be assessed using the EoE Endoscopic Reference Score (EREFS) (Hirano et al. Gut. 2013; 62:489-495) which is composed of 5 classification categories. The classification features include edema, fixed rings, exsudates, furrows and stricture where grade 0 indicates the absence of the feature and grade 2 and 3 increasing severity of the feature. |
within 48 months
|
Disease activity Score
Time Frame: within 48 months
|
Assessment of a Disease Activity Score: The Disease Activity Score will be assessed on the basis of the Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) instrument (Dis Esophagus. 2007;20 (2):130-4) and consists of a questionnaire rated from 0 to 5 where 0 indicates no symptoms while 5 indicates strong symptoms of heartburn and difficulties in swallowing that incapacitates to do daily activities. |
