The investigators hypothesize that persons with the particular cluster of symptoms that are due to supraesophageal reflux (SER) will have complete resolution of those symptoms with adequate acid suppression when a PPI is administered for 6 months.
Drug: Sugar Pill
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
||Which Supraesophageal Reflux Symptoms Reliably Respond to PPI Therapy: A Large Simple Trial
Primary Outcome Measures:
- To determine which symptom(s) are predictive of SER based on a complete response to PPI therapy [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To determine which symptoms demonstrate partial response with PPI therapy [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
- To determine which features of a patient's history are predictive of a positive response to PPI therapy [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
- To determine which features of a patient's history are predictive of a lack of response to PPI therapy [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
- To develop a scoring system for the Supraesophageal Reflux Questionnaire (SRQ) that would predict a diagnosis of SER [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

|Accepts Healthy Volunteers:
- Primary complaint includes one of the following symptoms: chronic cough (dry, hacking, or nocturnal), hoarseness, sore throat, globus sensation, or throat clearing. These symptoms will be identified by a yes response to SRQ (Appendix 7) items 2, 3, 4, 5, 6, and 8. Furthermore, symptom(s) must be chronic (present for at least 1 month), and recurrent (at least twice per week). These criteria correspond to SRQ columns on page 3-5. The first column asks: When in your life did you first notice this symptom? A response with either number 2, 3, 4, or 5 meets criteria for chronic. The second column asks: How frequently have you noticed the symptom? A response with either number 3, 4, or 5 meets criteria for recurrent.
- History of head and neck cancer/radiation/surgery (SRQ items 15, 16, 17)
- History of esophagus/stomach surgery (SRQ item 22)
- Peptic or duodenal ulcer disease; stomach or gastric ulcer disease; history of esophageal stricture, or Barrett's esophagus, or esophagitis, or tumor of the esophagus or stomach (SRQ item 23 and review of electronic surgical records of Mayo Clinic patients)
- Presence of alarm symptoms (hemoptysis, unexplained loss of 10 or more pounds in the past 3 months), obtained from Appendix 5 for Community Subjects, medical record for clinic subjects. History of dysphagia, defined as a yes answer to SRQ item 7.
- PPI use within 4 weeks, obtained from Appendix 5 for Community Subjects, medical record for clinic subjects
- Use of warfarin or digoxin, obtained from Appendix 5 for Community Subjects, medical record for clinic subjects
- Pregnancy at the time of enrollment, based on urine pregnancy test
- Inability to understand or read English at a 6th grade level
- Residence outside of the United States of America (USA)
- Age younger than 18 years old
