Using neuromodulators to treat gut-brain communication disorders in GERD patients

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

Not applicable Interventional Hualien Tzu Chi General Hospital · NCT06778824

This study is testing if certain medications for mood can help people with GERD who haven't found relief from regular treatments feel better and improve their quality of life.

What this trial studies

This clinical trial investigates the effectiveness of neuromodulators, specifically tricyclic antidepressants (TCA) and selective serotonin reuptake inhibitors (SSRI), in treating patients with gastroesophageal reflux disease (GERD) who have not responded to standard proton pump inhibitor (PPI) therapy. Participants will complete a series of questionnaires assessing their symptoms and quality of life before being randomly assigned to one of three treatment groups: TCA, SSRI, or PPI for 12 weeks. The study aims to determine if these neuromodulators can alleviate chronic esophageal symptoms related to disorders of gut-brain interaction. A total of 210 participants will be recruited for this trial.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with chronic esophageal symptoms linked to gut-brain communication issues.

Not a fit: Patients with structural esophageal diseases or significant gastrointestinal motility disorders are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide significant relief for patients suffering from refractory GERD and related gut-brain disorders.

How similar studies have performed: While the use of neuromodulators in treating gut-brain disorders is promising, this specific approach in GERD patients is relatively novel and has not been extensively tested.
