6. Project Abstract 
ÿPlease provide a summary of the key points of this project within 500 words, and create customized keywords based 
on the nature of the project.ÿ 
 
Gastroesophageal reflux disease (GERD) poses a challenging medical condition to manage, with 
up to 40% of patients showing refractory to standard medical intervention, which usually begins with 
a proton pump inhibitor (PPI). Among these cases, esophageal disorders of gut-brain interaction 
(DGBI), such as reflux hypersensitivity and functional heartburn, or GERD patients with concurrent 
occurrences of these conditions, constitute more than 90% of the patients who did not respond to 
twice-daily PPI treatment. Esophageal visceral hypersensitivity and hypervigilance are the two 
pathways that drive esophageal DGBI and symptoms. The Rome IV esophageal disorders, 
encompassing functional chest pain, functional heartburn, globus, functional dysphagia, and reflux 
hypersensitivity, are defined by present with symptoms originating from the esophagus without 
detectable evidence of structural, inflammatory, or motor disorders. Diagnosing esophageal DGBI 
necessitates testing involving endoscopy, pH-impedance monitoring, and high-resolution manometry. 
Neuromodulators form the basis of the pharmacological strategy for managing various esophageal 
DGBI and symptoms, modulating both peripheral and central hyperalgesia. Increasing evidence 
supports the use of brain-gut behavioral therapies, such as gut-directed hypnotherapy and cognitive 
behavior therapy, as effective treatments for a variety of DGBIs. However, the efficacy of 
neuromodulators or cognitive behavior therapy in treating esophageal DGBI and related symptoms 
remains largely unexplored. The primary objective of this study is to examine the efficacy of 
neuromodulators in managing esophageal DGBI. Additionally, we will explore various classes of 
neuromodulators and subtypes of esophageal DGBI to ascertain whether there are differing levels of 
effectiveness across these conditions. The findings from this study will contribute to a better 
understanding of the pathophysiology of esophageal DGBI and GERD with refractory symptoms. 
These clinical insights may then offer valuable guidance for future therapeutic approaches in DGBI 
patients who experience esophageal symptoms and do not respond to PPI treatment.

7. Background and Objectives of the Research Project 
ÿPlease provide a detailed description of the background, objectives, significance of this research project, as well as the 
research status both domestically and internationally related to this project. Also, include a review of important references 
and literature.ÿ 
 
Research Background 
çPathophysiological Mechanisms and Importance of Gastroesophageal Reflux Disease (GERD) 
Gastroesophageal reflux disease (GERD) is defined as a condition where stomach contents 
flow back into the esophagus, resulting in symptoms or mucosal injury. Common typical symptoms 
include heartburn or acid reflux, while atypical symptoms may include chest tightness, a sensation 
of a foreign body in the throat, hoarseness, or chronic cough. Clinically, GERD is a common 
chronic disease. In the United States, where symptoms occur at least once a week, up to 30% of 
adults are affected by GERD; in East Asia, the prevalence is 5-10%, but there is a growing trend in 
its incidence. 
There are many possible pathogenic mechanisms for GERD, including lower esophageal 
sphincter (LES) dysfunction or structural abnormalities, ineffective esophageal motility, esophageal 
mucosal integrity defects, esophageal hypersensitivity, the formation of acid pockets after meals, 
the composition of gastric refluxate, and delayed gastric emptying. Currently, the most common 
diagnostic method involves observing damage to the distal esophageal mucosa through endoscopy 
or confirming abnormal gastric acid exposure via a 24-hour pH monitoring test. Based on the results 
of endoscopy and esophageal pH monitoring, GERD patients can be classified into two categories: 
erosive esophagitis (EE) and non-erosive reflux disease (NERD). 
Repeated gastric acid exposure to the distal esophagus not only causes mucosal damage but 
may also lead to severe complications such as esophageal stricture, Barrett9s esophagus, and 
esophageal adenocarcinoma. Statistics show that in the United States, medical and non-medical 
losses due to GERD exceed $930 million annually. Therefore, GERD has become an important 
issue both clinically and in national public health policies in recent years. 
 
ç Disorders of gut-brain axis interaction in esophagus 
Disorders of gut-brain axis interaction (DGBI) refer to gastrointestinal diseases that present 
with symptoms but no organic abnormalities, which were previously referred to as functional 
gastrointestinal disorders. In the recent Rome IV criteriaÿ11 In the esophageal context, the Rome 
IV criteria define five conditions: functional chest pain, reflux hypersensitivity (RH), functional 
heartburn (FH), globus, and functional dysphagia. Epidemiologically, the prevalence of esophageal 
disorders related to gut-brain axis interaction is still not well understood. Past population-based 

Version Dateÿ(Version 8, 11/19/2024) 
E6A0021096-10                                                                               19 
studies have shown that the prevalence of non-cardiac chest pain is approximately 19-33%ÿ12,13 
Further generation-based analysis of the population with psychogenic chest pain revealed that 
approximately 32-35% of them were diagnosed with functional chest pain.14 In terms of reflux 
hypersensitivity, among patients with non-erosive mucosal damage in the esophagus, approximately 
10-36% are diagnosed with esophageal hypersensitivity.15,16 Functional heartburn has an unknown 
prevalence due to the limitations of current diagnostic tools and receiver operating characteristic 
(ROC) curves. Globus, on the other hand, is a commonly encountered disorder of gut-brain axis 
interaction in clinical practice. Research reports indicate that 46% of healthy adults have 
experienced globus at some point.17 Functional dysphagia is the least common, and its prevalence 
remains unclear to this day. 
In terms of definition, patients must have chronic esophageal symptoms lasting at least three 
months, with the first occurrence of symptoms being more than six months before the diagnosis of 
the disease. Additionally, structural, inflammatory, motility, and metabolic abnormalities in the 
esophagus must be excluded.1 Therefore, to diagnose esophageal disorders related to gut-brain axis 
interaction, upper gastrointestinal endoscopy, esophageal pH-impedance testing, and high-resolution 
esophageal manometry are required to exclude other esophageal diseases that may cause similar 
symptoms. Regarding the pathophysiological mechanisms, it is currently believed that they may be 
related to esophageal visceral hypersensitivity and hypervigilance, but the exact mechanisms still 
require further research for confirmation. In terms of diagnostic criteria, according to the Rome IV 
criteria, the definition is as follows:11 
ø Functional Chest Pain: 
(1) Occurs g1 time per week with non-cardiac chest pain or chest tightness; 
(2) No associated heartburn or dysphagia; 
(3) Symptoms are not related to gastroesophageal reflux disease (GERD) or eosinophilic 
esophagitis; 
(4) No significant esophageal motility disorders. 
ø Functional Heartburn: 
(1) Occurs g2 times per week with substernal symptoms such as heartburn or chest pain; 
(2) Symptoms do not improve with antisecretory therapy; 
(3) Symptoms are not related to gastroesophageal reflux disease (GERD) or eosinophilic 
esophagitis; 
(4) No significant esophageal motility disorders. 
ø Reflux Hypersensitivity (Esophageal Hypersensitivity): 
(1) Occurs g2 times per week with substernal symptoms such as heartburn or chest pain; 
(2) Endoscopy is normal, and eosinophilic esophagitis must be excluded; 
(3) No significant esophageal motility disorders;

E6A0021096-10                                                                               21 
percentage of time during a 24-hour monitoring period in which the distal esophageal pH value is less 
than 4. The Lyon Consensus on the diagnosis of gastroesophageal reflux disease (GERD) states that 
an acid exposure time (AET) of less than 4% is considered physiological reflux, while an AET greater 
than 6% is considered pathological reflux. Additionally, if the total number of reflux episodes in 24 
hours is less than 40, it is considered normal, while more than 80 episodes is considered abnormal.8 
The combination of parameters such as acid exposure time (AET), number of acid reflux episodes, 
number of acid reflux episodes lasting more than five minutes, and the longest reflux episode duration 
can be used to assess the severity of reflux.19 By combining esophageal pH testing with impedance 
values, it is possible to detect the direction of reflux, as well as the reflux of weakly acidic, alkaline 
fluids, or gases.20 During the detection period, patients are required to record all esophageal symptoms 
occurring during the esophageal pH-impedance testing. The physician will then compare these 
recorded symptoms with the reflux events documented by the pH-impedance monitor to calculate the 
association between reflux and symptoms (Symptom Association Probability, SAP, and Symptom 
Index, SI).21 
Based on the above criteria for esophageal pH testing and endoscopic examination results, 
patients with esophageal reflux symptoms can be classified into erosive esophagitis, non-erosive 
reflux disease, esophageal hypersensitivity, and functional heartburn. Erosive esophagitis is 
characterized by visible mucosal damage at the distal esophagus during endoscopy; non-erosive 
reflux disease is identified by normal mucosa on endoscopy and pathological prolongation of the acid 
exposure time (AET) at the distal esophagus on esophageal pH testing; esophageal hypersensitivity 
presents with a normal AET, but the symptoms are associated with reflux events (refluxate may be 
acidic, weakly acidic, or weakly alkaline) as seen on pH-impedance testing; functional heartburn 
occurs when there are symptoms of gastroesophageal reflux disease, but both endoscopic examination 
and AET are normal. For disorders of gut-brain axis interaction, including functional chest pain, 
globus, and functional dysphagia, in addition to normal endoscopic and AET results, patients must 
not have significant esophageal motility disorders and must meet the diagnostic criteria related to 
esophageal symptoms, as well as the onset and duration of symptoms.  
Current diagnostic tools, such as questionnaires, proton-pump inhibitor trials, and endoscopic 
examination, have low sensitivity and specificity for diagnosing gastroesophageal reflux disease 
(GERD). While esophageal pH (or pH-impedance) testing is considered the gold standard for 
diagnosing GERD, it can only detect and diagnose reflux events that occur during the test period. 
Among these, catheter-based esophageal pH testing is limited because it can only detect reflux 
activity during the 24-hour test period. Additionally, patients may experience discomfort from the 
catheter, which could lead to changes in their daily activities, thereby potentially affecting the 
diagnostic results to varying degrees.222-23 The 96-hour wireless capsule-based esophageal pH 
monitoring, compared to the 24-hour esophageal pH-impedance testing, not only avoids the

E6A0021096-10                                                                               22 
discomfort caused by the catheter but also extends the monitoring period to 96 hours. Previous studies 
have indicated that up to one-third of patients diagnosed with functional heartburn based on 24-hour 
esophageal pH-impedance testing had their diagnosis corrected to non-erosive reflux disease after 
undergoing 96-hour wireless capsule-based esophageal pH monitoring.24 However, the 24-hour 
esophageal pH-impedance testing can improve the probability of diagnosing or excluding 
gastroesophageal reflux disease (GERD) by calculating the mean nocturnal baseline impedance 
(MNBI). The mean nocturnal baseline impedance is derived by recording the 10-minute average 
impedance values during the patient's sleep at three one-hour intervals (1:00, 2:00, 3:00). Recent 
studies have indicated that the mean nocturnal baseline impedance is associated with mucosal 
integrity, acid exposure time, and reflux symptoms.25, 26 
 
çThe Treatment Dilemma of Refractory Gastroesophageal Reflux Disease and Esophageal 
Brain-Gut Axis Communication Disorders 
  Proton pump inhibitors (PPIs) are the primary medications used to treat gastroesophageal reflux 
disease. Although they are highly effective in improving typical heartburn symptoms in patients with 
erosive esophagitisÿ27-29 However, their effectiveness in treating non-erosive gastroesophageal reflux 
disease (NERD) is less than ideal. According to statistics, up to 50% of patients treated with proton 
pump inhibitors (PPIs) for suspected reflux symptoms still experience persistent symptoms.1,30 
Studies have indicated that most gastroesophageal reflux disease (GERD) patients who are 
unresponsive to proton pump inhibitor (PPI) treatment have a normal acid exposure time (AET).32 In 
patients with heartburn who remain unresponsive to high-dose proton pump inhibitor (PPI) treatment, 
more than 90% are diagnosed with esophageal hypersensitivity or functional heartburn.31,32 In 
addition, patients with pathological reflux may also have concurrent esophageal brain-gut axis 
communication disorders. The complex pathophysiological mechanisms of gastroesophageal reflux 
disease (GERD) and the limited understanding of brain-gut interaction contribute to the poor 
treatment outcomes in such patients. Recent consensus suggests that non-reflux factors, such as 
altered perception or visceral hypersensitivity, may be associated with the refractory symptoms of the 
esophagus.33 
çTreatment Strategies for Refractory Gastroesophageal Reflux Disease and Esophageal 
 Brain-Gut Axis Communication Disorders 
  The treatment strategies for refractory gastroesophageal reflux disease (GERD) and esophageal 
brain-gut axis communication disorders remain unclear. Currently, it is believed that esophageal 
hypervigilance, anxiety, and autonomic arousal are the primary factors influencing the severity of 
symptoms and the response to reflux burden. The Esophageal Hypervigilance and Anxiety Scale

E6A0021096-10                                                                               23 
(EHAS) has been recently validated in studies as an effective tool for assessing esophageal 
hypersensitivity.34 Therefore, it is considered a helpful tool in diagnosing esophageal brain-gut axis 
communication disorders. Neuromodulators are medications used clinically to treat these disorders. 
Previous research has shown that neuromodulators can effectively reduce symptoms in patients with 
irritable bowel syndrome (IBS) or functional dyspepsia by modulating visceral hypersensitivity 
through central and peripheral mechanisms.35,36 Therefore, using neuromodulators to regulate visceral 
hypersensitivity and esophageal hypervigilance in esophageal brain-gut axis communication 
disorders is considered a feasible strategy. However, a systematic review of the literature shows that 
among the few available randomized controlled trials, the efficacy of neuromodulators in the various 
subtypes of esophageal brain-gut axis communication disorders is inconsistent.37 Therefore, whether 
neuromodulators can be widely used in the treatment of these disorders still requires more supporting 
evidence. 
 
 
Research Objectives 
The objectives of this studyÿ 
To explore the impact of neuromodulators on disorders related to abnormal communication in 
the esophageal-brain-gut axis.  
Hypothesis: 
(1) Patients with disorders related to abnormal communication in the esophageal-brain-gut axis 
experience esophageal symptoms due to visceral hypersensitivity and heightened esophageal 
sensitivity, which affect their physical and mental health, sleep, and quality of life. 
Neuromodulators may alleviate symptoms and their associated impacts. 
(2) The effectiveness of neuromodulators may vary among patients with different subtypes of 
esophageal-brain-gut axis communication disorders. 
(3) The effectiveness of different neuromodulators may vary within the same subtype of esophageal-
brain-gut axis communication disorders.

research data collected by each center will be managed and stored by the respective center's director. 
The hospital directors will assist in consolidating the research data from their institution, and the 
electronic data will be coded for identification. After the data is compiled, it will be sent back to the 
principal investigator. Additionally, the research physicians and staff at each participating center will 
have regular video conferences (every 2 months) to discuss and report on the progress of the study. 
 
Statistical Analysis 
All data will undergo normality testing using the Kolmogorov-Smirnov test. If continuous 
variables follow a normal distribution, they will be expressed as means and standard deviations; if 
not, they will be presented as medians and interquartile ranges. 
For categorical variables, the Chi-square test or Fisher's exact test will be used for analysis. 
Continuous variables that are normally distributed will be analyzed using the unpaired t-test, while 
non-normally distributed continuous variables will be analyzed using the Mann-Whitney U test. 
For comparisons involving more than three groups, if the data are normally distributed, an 
ANOVA with post hoc tests will be conducted. If the data are non-normally distributed, the 
Kruskal-Wallis test will be applied. A p-value of less than 0.05 will be considered statistically 
significant. 
Statistical analyses will be performed using SPSS 19 for Windows (SPSS, Inc., Chicago, IL, 
USA). 
 
Clinical Significance and Originality of This Study

to explore the effects of neuromodulators on diseases related to esophageal-brain-gut axis 
communication abnormalities. Patients with such conditions often experience more severe 
esophageal symptoms due to excessive visceral sensitivity and esophageal hypersensitivity. We 
will further compare the therapeutic effects of neuromodulators across different subtypes of 
esophageal-brain-gut axis communication abnormalities. Additionally, we will investigate the 
differences in treatment outcomes using various types of neuromodulators for these conditions.

esophageal awareness in esophageal-brain-gut axis communication abnormalities and refractory 
gastroesophageal reflux disease. It will also help us establish the role of neuromodulators in 
esophageal-brain-gut axis communication abnormalities and their impact on the regulation of 
brain-gut axis communication. 
(2) Clinically, patients with esophageal-brain-gut axis communication abnormalities often 
experience delayed diagnoses and poor treatment outcomes. The results of this study will enable 
us to intervene early and accurately in such brain-gut axis communication abnormality cases, 
helping clinical healthcare providers develop precise and effective treatment strategies. 
3. The expected training for the participating staff. 
In addition to receiving general research training (such as experimental design and execution, 
questionnaire creation and completion, result analysis and statistics, chart creation, oral 
presentations, writing papers, and the submission process), participants will also have the 
opportunity to learn more specialized research design and numerical analysis techniques.
