About this study

Official title: Phenotypic Characterization of Pediatric Patients With Esophageal Eosinophilia and Biomarkers Investigation for the Diagnosis of Eosinophilic Esophagitis

The purpose of this study is to find out some potential biomarkers for the Eosinophilic Esophagitis (EoE) in pediatric patients through the prospective clinical characterization and assessment of samples collected during the diagnostic process

Read the detailed description

This study collects clinical information from pediatric patients between 0-18 years old who have been undergoing upper gastrointestinal endoscopy due to general complaints. The demographic, clinical symptoms, endoscopy, pH monitoring, and histology data are assessed during the diagnostic process. In the baseline endoscopy procedure samples (blood, saliva, esophageal tissue, and esophageal mucus) are taken. After diagnostic process of EoE and Gastroesophageal reflux disease (GERD) supported by International Guidelines the patients are divided into three groups - EoE, GERD, and Control.

The techniques are used for patients characterization and assessment:

  1. Symptoms score: General symptom score and/or Pediatric Eosinophilic Esophagitis Symptom Score (PEESS v2.0) - translated and adapted version for Brazilian Portuguese
  2. Endoscopic Score: Eosinophilic Esophagitis (EoE) Endoscopic Reference Score (EREFS)
  3. Peak eosinophil count (PEC) and histological features description
  4. Proteomic analyses
  5. Microbiome analyses
  6. Immunohistochemistry analyses

ControlExclusion diagnosis of EoE or GERD, with non specific gastrointestinal general complaints.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biomarkers for the diagnose of Pediatric Eosinophil Esophagitis

    Identify diagnostic biomarker, able to distinguish EoE patients from GERD patients and other nonspecific gastrointestinal complains

    Measured: 2016 August - 2017 March and 2018 November-December

Secondary outcomes (3)
  1. Endoscopic features of EoE

    Evaluation of the EREFS 'ability (endoscopic reference score) to identify EoE patients and the inflammatory or fibrosis phenotype

    Measured: 2017 January-March and 2018 November-December

  2. Symptoms of active EoE

    Evaluation of the symptom score's ability to identify EoE patients in active disease

    Measured: 2017 January-March and 2018 November-December

  3. Histological features of EoE

    Evaluation of the histologic score's ability to identify EoE patients and the inflammatory or fibrosis phenotype

    Measured: 2017 January-March and 2018 November-December

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Biomarkers for the diagnose of Pediatric Eosinophil Esophagitis (time frame: 2016 August - 2017 March and 2018 November-December). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03069573, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
