Study Description

Brief Summary

Consecutive patients aged 18-65 years who go to the gastroenterology clinic presented with upper gastrointestinal discomfort would be included. All patients underwent upper endoscopy or an ambulatory 24-h pH(Potential Of Hydrogen) monitoring.Pathologic esophageal acid reflux was defined as the percentage total time for which a pH value < 4 was >4.2 % in the distal esophagus. Then, patients were treated with esomeprazole 20 mg twice daily for 28 days. The symptom scores were measured by the frequency score multiplied by the severity scores of the predominant symptom before and at the end of the treatment, and the " PPI test " was defined as positive if the overall scores of the predominant dyspeptic symptom in the fourth week decreased by >50 % compared with those of the baseline.

GERD is defined by either 24-hour impedance-pH monitoring or positive PPI(proton pump inhibitor) test or positive result from endoscopy. The percentage of each symptom of GERD in the symptom questionnaire in Chinese outpatients in Gastroenterology department will be calculated. The symptom of the highest percentage will be the primary symptom.

Condition or Disease Intervention/Treatment Phase
  • Drug: Esomeprazole MUPS, 20 mg

Detailed Description

Primary Objective:To define the primary symptom of GERD in Chinese outpatients in Gastroenterology department Secondary Objective:1. To investigate the symptom distribution of patients who present with symptoms originated from upper gastrointestinal tract and have pathologic esophageal reflux established by 24-hour impedance-pH monitoring, upper endoscopy, or proton pump inhibitor test.

  1. To evaluate the life quality of patients with atypical GERD symptoms (symptoms except heartburning and regurgitation) 3. To investigate the diagnostic value of proton pump inhibitor trial to diagnose GERD with atypical reflux symptoms 4. To investigate the predictive value of Gerd Q to diagnose GERD with atypical reflux symptoms with heartburn or regurgitation

Arms and Interventions

Arm Intervention/Treatment
Participants with upper gastrointestinal symptoms

Participants are stratified at baseline based on their main upper gastrointestinal symptoms and then evaluated for GERD using different methods (i.e., reflux esophagitis on endoscopy or positive acid exposure time (AET) on reflux monitoring). Patients would then be given Esomeprazole MUPS( Multiple Unit Pellet System)20 mg bid for evaluating the ability of the PPI Test for GERD. According to the guidelines, the duraion of PPI treatment was 4 weeks and 8 weeks for endoscopy negative patients and patients has reflux esophagitis, respectively.

Drug: Esomeprazole MUPS, 20 mg
According to the guidelines, the PPI treatment duration would be 8 weeks(Esomeprazole MUPS, 20 mg bid) for patients with reflux esophagitis and 4 weeks (Esomeprazole MUPS, 20 mg bid) for patients with normal findings on endoscopy.

    Primary Outcome Measures

    1. The Primary Symptom of GERD in Chinese Outpatients in Gastroenterology Department [over 3 years]

      GERD can be diagnosed by more than one different criteria (i.e."reflux esophagitis on endoscopy"; "positive acid exposure time (AET) on reflux monitoring";"Either reflux esophagitis on endoscopy or positive AET on reflux monitoring") in a single participant. When different criteria was used to diagnose GERD, the percentage of GERD patients with different predominant symptom will be calculated. The symptom of the highest percentage will be the primary symptom.

    Secondary Outcome Measures

    1. The Percentage of Participants Diagnosed With Reflux Esophagitis Using Endoscopy Among Participants With Different Main Baseline Symptoms [over 3 years]

      The percentage of paticipants diagnosed with reflux esophagitis on endoscopy among patients with different main symptom in the symptom questionnaire in Chinese outpatients in Gastroenterology department will be calculated.

    2. The Percentage of Participants Diagnosed With Pathological Acid Reflux Using Reflux Monitoring Among Participants With Different Main Baseline Symptoms [over 3 years]

      The percentage of paticipants diagnosed with pathological acid reflux using reflux monitoring among patients with different main baseline symptom in the symptom questionnaire in Chinese outpatients in Gastroenterology department will be calculated.

    3. The Life Quality of GERD Patients Who Were Diagnosed by Either Reflux Esophagitis on Endoscopy or Positive Acid Exposure Time(AET) on Reflux Monitoring and Presented With Different Main Baseline Symptoms [over 3 years]

      The life quality of GERD patients with different main symptoms before PPI test will be measured via the MOS 36-item short form health survey (SF-36), in which higher scores mean a better quality of life. Its maximum score is 796.5, and the minimum score is 36.5.

    4. The Sensitivity of PPI Test for Diagnosis of GERD [over 3 years]

      The sensitivity of PPI test for the diagnosis of GERD in patients with typical or atypical reflux symptoms will be calculated. The presence of reflux esophagitis on upper endoscopy and/or pathological acid reflux on 24-hour pH monitoring are considered as the "gold standard" for the diagnosis of GERD.

    5. The Specificity of PPI Test for Diagnosis of GERD [over 3 years]

      The specificity of PPI test for the diagnosis of GERD in patients with typical or atypical reflux symptoms will be calculated. The presence of reflux esophagitis on upper endoscopy and/or pathological acid reflux on 24-hour pH monitoring are considered as the "gold standard" for the diagnosis of GERD.

    6. The Sensitivity of GERDQ for Diagnosis of GERD [over 3 years]

      The sensitivity of GERDQ for the diagnosis of GERD in patients with typical or atypical reflux symptoms will be calculated. The presence of reflux esophagitis on upper endoscopy and/or pathological acid reflux on 24-hour pH monitoring are considered as the "gold standard" for the diagnosis of GERD.

    7. The Specificity of GERDQ for Diagnosis of GERD [over 3 years]

      The specificity of GERDQ for the diagnosis of GERD in patients with typical or atypical reflux symptoms will be calculated. The presence of reflux esophagitis on upper endoscopy and/or pathological acid reflux on 24-hour pH monitoring are considered as the "gold standard" for the diagnosis of GERD.

    Study Results

    Participant Flow

    Recruitment Details Four hundred consecutive patients with upper gastrointestinal (GI) symptoms were screened, 19 patients who didn't meet the inclusion criteria and 7 patients with major motility disorders on high resolution manometry were excluded. Thus, a total of 374 patients were finally enrolled in the current study.
    Pre-assignment Detail The current study was a single Arm study where all participants with upper GI symptoms were enrolled and tested for gastro-esophageal reflux disease (GERD) via endoscopy and 24-hour reflux monitoring. Participants were then given proton pump inhibitor(PPI) treatment and the course was decided base on the endoscopy findings.
