Esophageal Visceral Hypersensitivity and Hypervigilance in Disorders of Gut-brain Interaction: the Roles of Neuromodulators

Обзор

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 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, investigators 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.

Подробное описание

Procedure steps： n Study One, each participant first completed a questionnaire that included the Gastroesophageal Reflux Disease Questionnaire (GERDQ, PROMIS GERD, DSI \& GSS, RSI), the Brief Esophageal Swallowing Difficulty Scale (BEDQ), the Esophageal Hypersensitivity and Anxiety Scale (EHAS), the Visceral Sensitivity Index (VSI), and the Sleep and Psychosocial Questionnaire (Pittsburgh Sleep Quality Index (PSQI), Taiwanese Depression Questionnaire (TDQ), State-Trait Anxiety Inventory (STAI), Functional Dyspepsia (FD) Questionnaire, Irritable Bowel Syndrome (IBS) Questionnaire, and the Quality of Life Questionnaire (SF-12, Northwest Esophageal Quality of Life Scale (NEQOL)). Completing the questionnaires took approximately 20 to 30 minutes.

Afterward, participants were randomly assigned by computer to receive either 12 weeks of treatment with a neuromodulator-tricyclic antidepressants (TCA), or a neuromodulator-selective serotonin reuptake inhibitors (SSRI), or 12 weeks of the control medication-proton pump inhibitors (PPI). Investigators plan to recruit 70 participants for the TCA group, 70 for the SSRI group, and 70 for the PPI group, with each participant having about a 1/3 chance of being assigned to one of these groups.

The tricyclic antidepressant (TCA) will be administered as 25 mg enteric-coated tablets (Department of Health Drug Code 047966), taken twice daily. The selective serotonin reuptake inhibitor (SSRI) will be administered as 50 mg enteric-coated tablets (Department of Health Drug Code 021780), taken once daily. The control medication, the proton pump inhibitor (PPI), will be given as 30 mg orally dissolving tablets (Department of Health Drug Code 024273), taken once daily.

At the end of the 12-week medication treatment, participants will complete another round of questionnaires to conclude the study.
