Brief Summary:
For ERD(erosive reflux disease), which pathogenesis is mainly the acid reflux mechanism, primary treatment is therefore PPI. However, NERD(non-erosive reflux disease) is much more complex than ERD and there are more factors causing the typical symptoms. As a result, there is no consensus for the treatment of NERD besides using PPI similar to GERD(gastroesophageal reflux diseas). This study intent to evaluate the effect of PPI(Esomezol) on NERD patients and analyze the improvement of symptoms and the factors related to the result.

Condition or disease Intervention/treatment Phase
Non-erosive Gatroesophageal Reflux Disease Drug: PPI Not Applicable

Detailed Description:
(1) Among GERD patients, EGD(esophagogastroduodenoscopy) must be done before 6 months and must prove there is no erosive lesion. (2) During EGD, esophagus mucosa histology will be taken for evaluation. (3) For NERD patients, Esomezol is given once a day (before breakfast meal), for whole 8 weeks. (4) PAGI-SYM and HAD-K is evaluated and score just before the administration of PPI, 4weeks after and 8weeks after the study initiation.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 62 participants
Intervention Model: Single Group Assignment
Intervention Model Description: There is only one arm in this study. Patients diagnosed as NERD will take PPI (Esomezol) for 8 weeks.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Treatment Response of Maintenance Dose of Proton Pump Inhibitor in Patients With Nonerosive Gatroesophageal Reflux Disease
Estimated Study Start Date : March 1, 2018
Estimated Primary Completion Date : January 20, 2020
Estimated Study Completion Date : January 20, 2020

Arm Intervention/treatment
Experimental: PPI
Drug: PPI
After the diagnosis of NERD through patient's symptom and endoscopy, PPI (esomezol) will be given for 8 weeks. The effect of PPI for NERD patients will be analyzed.
Other Name: Esomezol®

Primary Outcome Measures :
  1. Proportion of PAGI-SYM score (0-2) patients after 8 weeks of PPI(Esomezol) [ Time Frame: 8 weeks ]
    Scoring the PAGI-SYM to analyze the satisfaction of symptoms (heartburn and regurgitation) after 8 weeks of PPI administration to NERD patients

Secondary Outcome Measures :
  1. The analysis of factors affecting the PAGI-SYM inculding immunolgic array and esophagus mucosal microbiota [ Time Frame: 8 weeks ]
    The analysis of complete symptom (regurgitation, heartburn) remission (PAGI-SYM score 0) after 8weeks of PPI
