Qualitative Validation of a Novel VR Program for Irritable Bowel Syndrome: A VR1 Study

The Role of Virtual Reality in the Management of Irritable Bowel Syndrome

PURPOSE OF REVIEW

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction that significantly impacts health-related quality of life (HRQOL). This article explores the potential role of virtual reality (VR)-based cognitive behavioral therapy (CBT) in treating patients with IBS.

RECENT FINDINGS

While CBT is a proven, skills-based therapy approach that modifies behaviors and alters dysfunctional thinking patterns to influence the gut-brain axis and improve IBS symptoms, it is rarely prescribed given a paucity of CBT-trained clinicians. We developed a novel VR program that delivers a standardized CBT program over an 8-week period to help patients manage their symptoms. In initial qualitative validation testing, patients expressed positive perceptions about using VR CBT for IBS. Home-based, standardized VR CBT has the potential to be an effective and scalable treatment option for patients with IBS. While initial studies have shown proof-of-concept definitive randomized controlled trials are needed to demonstrate the efficacy of self-administered VR CBT in IBS.

The gut microbiome in disorders of gut-brain interaction

Functional gastrointestinal disorders (FGIDs), chronic disorders characterized by either abdominal pain, altered intestinal motility, or their combination, have a worldwide prevalence of more than 40% and impose a high socioeconomic burden with a significant decline in quality of life. Recently, FGIDs have been reclassified as disorders of gut-brain interaction (DGBI), reflecting the key role of the gut-brain bidirectional communication in these disorders and their impact on psychological comorbidities. Although, during the past decades, the field of DGBIs has advanced significantly, the molecular mechanisms underlying DGBIs pathogenesis and pathophysiology, and the role of the gut microbiome in these processes are not fully understood. This review aims to discuss the latest body of literature on the complex microbiota-gut-brain interactions and their implications in the pathogenesis of DGBIs. A better understanding of the existing communication pathways between the gut microbiome and the brain holds promise in developing effective therapeutic interventions for DGBIs.

Irritable bowel syndrome - less irritable, or better treatments?

PURPOSE OF REVIEW

Irritable bowel syndrome (IBS) is a chronic, often bothersome disorder of gut-brain interaction (DGBI) characterized by abdominal pain associated with a change in stool frequency and/or caliber. Recent advancements have improved our understanding of the underlying pathophysiology, thus opening new avenues for therapeutic intervention. The purpose of this review is to summarize the current literature regarding treatment modalities for IBS.

RECENT FINDINGS

Altering the gut microbiome via probiotic and antibiotic administration, avoiding dietary triggers, and modulating the gut-brain axis have all proven efficacious for the management of IBS symptoms. Several gut-specific pharmacotherapies are approved for the treatment of IBS, many of which primarily address either diarrhea or constipation, although many patients remain symptomatic despite appropriate use. Brain-gut behavioral therapies (BGBTs) are increasingly used to treat symptoms of IBS, particularly in those who do not respond to traditional therapies. Virtual reality represents an exciting new approach to treating DGBIs, like IBS, though data are limited.

SUMMARY

As our understanding of IBS continues to evolve, so should our therapeutic approach. Individualizing the therapeutic approach is of utmost importance.
