Brief Summary
This study aims to elucidate the relationship between the microbiome, inflammation, and the microenvironment in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC), with the end goal of developing a non-endoscopic testing strategy based on pathogenic factors to identify patients at highest risk for EAC. To accomplish this the investigators will enroll 100 patients with known BE (50 with dysplasia or EAC) and 50 subjects without BE undergoing upper endoscopy. Prior to endoscopy each subject will undergo three minimally invasive potential screening and surveillance tests: saliva (oral microbiome), breath test (exhaled volatile organic compounds), and tethered capsule sponge sampling (methylated DNA markers). The study will evaluate these novel tests in combination with clinical and anthropometric factors to describe an optimal strategy for BE screening and monitoring.

Outcome Measures
Primary Outcomes (1)
Oral and esophageal 16S rRNA gene sequencing
Oral and esophageal microbiome
1 day
Secondary Outcomes (2)
Esophageal tissue RNA-Seq
1 day
Gastric aspirate mass spectrometry
1 day
Study Arms (2)
Barrett's esophagus
Barrett's esophagus, without or with dysplasia or adenocarcnoma
Controls
Non-BE endoscopic controls
Interventions
Subjects swallow a tethered capsule sponge sampling device, which is then withdrawn through the mouth after an interval of 5 minutes.
Subjects breathe into the device, which then records an exhaled volatile organic compounds (VOC) signature.
Eligibility Criteria
Patients with or without Barrett's esophagus already scheduled for upper endoscopy.
You may qualify if:
- (for BE patients)
- History of histologically confirmed BE, defined as endoscopically-suspected BE with intestinal metaplasia with goblet cells on esophageal biopsies
- BE length M≥2
- Taking proton pump inhibitors at least once daily for 3 months prior to enrollment
- Age ≥18
You may not qualify if:
- History of gastric cancer or esophageal squamous cell cancer
- History of gastric or esophageal surgery
- Use of antibiotics or systemic immunosuppressants within three months prior to the date of endoscopy (intranasal and inhaled steroids are allowed)
- Known untreated esophageal stricture or uninvestigated dysphagia
- Inability to give informed consent
- (BE patients only) History of prior endoscopic therapy for BE except a history of prior endoscopic mucosal resection (EMR) of focal lesions without subsequent ablative therapy is permitted
