Brief Summary:

The purpose of this study is to assess the clinical efficacy of proton pump inhibitors in comparison to aerosolized swallowed steroids for the treatment of eosinophilic esophagitis (EE). EE is an increasingly recognized disorder that has been associated with dysphagia and food impaction. The presence of anatomical abnormalities in the esophagus such as longitudinal furrows, corrugated rings and a narrow caliber esophagus with friable mucosa are classic endoscopic findings. Diagnosis is established with the histologic finding of large numbers (> 15) of eosinophils per high power field. The underlying pathologic mechanism remains poorly understood but food allergies and aeroallergens have been implicated. It is well known that gastroesophageal reflux disease (GERD) may cause esophageal eosinophilia, but it is unclear whether a complex relationship exists between GERD and EE, as recent data suggests. Furthermore, a large number of patients with clinical presentations and endoscopic findings highly suggestive of EE which is confirmed on histology are responding favorably to proton pump inhibitors.

The aims of the study are to (1) compare the clinical efficacy of aerosolized swallowed Fluticasone to Esomeprazole for the treatment of eosinophilic esophagitis, (2) determine whether proton pump inhibitors are effective in the treatment of eosinophilic esophagitis, (3) determine the number of patients with eosinophilic esophagitis that have coexisting gastroesophageal reflux disease, and (4) correlate change in eosinophil count to improvement in symptoms before and after therapy.

Actual Study Completion Date : October 2010

Arm Intervention/treatment
Active Comparator: Swallowed fluticasone Drug: Swallowed fluticasone
440 µg twice daily for 8 weeks

Active Comparator: Esomeprazole Drug: Esomeprazole
40 mg once daily for 8 weeks

Primary Outcome Measures :
  1. Number of Participants Who Responded [ Time Frame: 8 weeks ]
    Histologic resolution of esophageal eosinophilia. Response is defined as achieving < 7 eosinophils/high power field in both the proximal and distal esophagus.

Secondary Outcome Measures :
  1. Symptom Score [ Time Frame: 8 weeks ]
    Using a validated questionnaire, symptoms will be assessed at baseline and following therapy.

  2. Endoscopic Change [ Time Frame: 8 weeks ]
    Following therapy, resolution of EE findings will be assessed.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with an established diagnosis of EE defined as > 20 eosinophils/HPF in the setting of dysphagia or food impaction.
  • Males and females age > 18 years of age.
  • Ability to undergo ambulatory pH monitoring.
  • DEERS (Defense Enrollment Eligibility Reporting System) eligible.
  • Willingness to take a one month holiday from a PPI or steroids if they have been prescribed this prior to enrollment.
  • Willingness to participate and have additional biopsies taken during endoscopy and answer a questionnaire.

Exclusion Criteria:

  • Patients < 18 years of age.
  • Inability to give consent.
  • Inability to undergo endoscopy or contraindications to endoscopy. Any medical condition or disorder (including drug allergies), which would preclude the use of conscious sedation or the ability to tolerate upper endoscopy.
  • Contraindications to proton pump inhibitors or steroids.
  • Inability to accurately fill out a short questionnaire.
  • Pregnant females. A urine beta human chorionic gonadotropin (BHCG) prior to endoscopy will be offered to all female patients of child bearing potential (exceptions include post-menopausal, hysterectomy or bilateral tubal ligation). Positive BHCG results will prevent enrollment.
  • Known coagulation abnormalities, thrombocytopenia and patients on coumadin.
