NCT05342168

Brief Summary

The aim of the present study is determining the accuracy, safety and tolerance of the CytospongeTM (expandable sponge within a gelatin capsule attached to a string) relative to traditional upper endoscopy and esophageal biopsies in older children and adolescents with a diagnosis of Eosinophilic Esophagitis (EoE) to follow up on treatment changes. The findings from this study could help determine whether the CytospongeTM is a more cost-effective alternative to traditional upper endoscopy for histologic follow-up in children and adolescents with EoE.

Outcome Measures

Primary Outcomes (1)

  • Eosinophil count per high power field obtained from Cytosponge supernant and endoscopic esophageal biopsies will be compared

    Comparison of histology by counting the number of eosinophilis seen per high power field results from supernatant sample obtained via mesh sponge withdrawal thru the esophagus to samples obtained by the gold standard traditional esophageal biopsy.

    1 week

Secondary Outcomes (3)

  • Likert scale (10 point) evaluating patient and caregiver satisfaction

    immediately following the endoscopy procedure

  • Questionairre evaluating Patient and caregiver satisfaction

    immediately following endoscopy procedure

  • Histology comparison of supernant obtained from sponge and esophageal pinch biopses

    one week

Study Arms (1)

Histology

EXPERIMENTAL

Specimen samples from the tradition pinch esophageal biopsy and the supernatant sample obtained from the mesh sponge (Cytosponge TM) will each be fixed and stained. The eosinophil count per high power field for the mesh sponge sample and the traditional biopsy sample will be compared for each subject.

Diagnostic Test: Using a swallowed expanding sponge (Cytosponge TM) to obtain sampling of the esophageal musosa

Interventions

A gelatin capsule containing the collapsed mesh sponge is swallowed with an attached string fixed to the cheek. After 8 minutes the gelatin capsule will have dissolved and the expanded soft mesh sponge can be with drawn sampling the surface of the esophagus on the way out. The sponge then will be spun and the supernant fixed, processed and stained.

Eligibility Criteria

Age10 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Previous histologic diagnosis of eosinophilic esophagitis (symptoms of esophageal dysfunction and at least 15 eosinophils per high-power field on esophageal biopsy and after a comprehensive assessment of non-EoE disorders that could cause or potentially contribute to esophageal eosinophilia).1
  • Capable of swallowing a capsule 3 cm in length (trial with 3 cm jelly candy).
  • to 18 years of age.
  • Male or female.
  • Able to give assent or consent.
  • Scheduled for an upper gastrointestinal endoscopy with biopsies on the same day to assess response to therapy and make decisions regarding further management.

You may not qualify if:

  • Unable to swallow the capsule.
  • Unable to give assent or consent.
  • History of esophageal stricture on either upper gastrointestinal barium study or previous upper gastrointestinal endoscopy of food impaction that required removal.
  • History of portal hypertension or esophageal varices.
  • History of solid organ transplantation.
  • Known bleeding diathesis.
  • On anticoagulation therapy.
  • Known platelet count less than normal for age.
  • Pregnancy.
  • Need for intubation during endoscopy.
  • History of previous esophageal surgery.
