GERD affects roughly 20% of the U.S. population and the direct and indirect costs of GERD are substantial, totaling close to 50 billion dollars per year. Evidence supports that a large proportion of this cost and poor clinical outcomes in GERD are related to poor healthcare decisions by both the physician and the patient. The problem of inappropriate GERD management stems from three main issues. First, the disease is heterogeneous and requires treatment informed by a precision model. Second, the current paradigm largely ignores the important brain-gut interactions that drive symptoms and healthcare utilization. Third, there is a paucity of well-performed comparative effectiveness trials focused on assessing treatments beyond acid suppression. We will use physiomarkers defined during the previous funding cycle to phenotype the patients and use cognitive behavioral interventions to modulate hypervigilance to test the Psycho-Physiologic Model of GERD. Cognitive Behavioral Therapy (CBT) is able to improve hypervigilance and symptom specific autonomic arousal and thus, we will test our theory that CBT can improve outcomes in GERD by targeting these two important psychologic stressors. We will also continue our focus on the interplay of psychology and physiology by determining whether increased mucosal permeability is associated with reflux perception and whether this is modified by hypervigilance and autonomic disruption.
OVERVIEW: In this randomized, sham-controlled phase II/III adaptive trial, we will randomize 250 subjects with symptoms of GERD to eCBT+ (esophageal Cognitive Behavioral Therapy) or sham-SOC (Standard of Care) Lifestyle Coaching. Each subject will receive 6 sessions of 45 minutes each delivered by telehealth. The study will be conducted at two institutions: Northwestern University and Washington University. The interventions will be delivered by GI Health psychologists based at Northwestern University. RANDOMIZATION AND BLINDING: Participants will be blinded as to the intervention they will r…

The CBT intervention is based on the theoretical framework that under stress (reflux symptoms) a person makes a rapid cognitive appraisal of the potential threat (automatic thoughts), leading to both emotional and physical responses in the body, thereby reacting behaviorally (avoidance, increased HCU) in an attempt to mitigate unpleasantness. CBT is a collaborative, present-focused treatment that utilizes a skills-based approach with home practice exercises. CBT targets automatic thoughts and appraisals of threat via education, self-monitoring of stressors and symptoms, and strategies to reframe problematic thinking patterns to more adaptive ones. Resonance frequency breathing (RFB) is achieved when a person breathes at a pace, typically 4 to 6 breaths per minute, that engages the body's baroreflex to modulate arousal. Prior research demonstrates 4 to 6 weeks of RFB training is sufficient to significantly increase baseline HRV with enduring effects for up to 6 months.
