AI Article Synopsis

  • Irritable bowel syndrome (IBS) affects 5%-10% of the population, causing significant discomfort for patients and a burden on society. Recent research suggests that vitamin D could help alleviate IBS symptoms, though evidence has been limited.
  • This meta-analysis reviewed 6 randomized controlled trials involving 572 IBS patients to assess the impact of vitamin D on gastrointestinal symptoms, revealing a significant reduction in symptom severity but no notable improvement in quality of life.
  • The findings indicate that vitamin D supplementation may be beneficial for IBS patients in managing their gastrointestinal symptoms, though further research is needed to confirm these effects on quality of life.

Article Abstract

Background & Aims: Approximately 5%-10% of the population in most geographical regions suffer from irritable bowel syndrome (IBS), which creates a significant burden on individual patients, their families, and society. Recent advances in IBS therapies have indicated that vitamin D supplementation is potential to relieve its symptoms, but evidence of this is lacking. This meta-analysis aimed to estimate the effect of vitamin D on gastrointestinal (GI) symptoms in IBS patients.

Methods: The PubMed, Embase, and Cochrane Central Register of Controlled Trials databases were searched from their inception to March 2022. Statistical analyses were performed with Stata 12.0 and Review Manager 5.4, and statistical significance was defined as  < 0.05. The pooled results are presented as weighted mean differences (WMD) and 95% confidence intervals (CI).

Results: The meta-analysis including 6 randomized controlled trials (RCT) with 572 patients found a significant difference in IBS symptom severity score (WMD, -34.88; 95% CI, -62.48 to -7.27;  = 0.013; random-effects model) but no significant difference in IBS quality of life score (WMD, 3.33; 95% CI, -5.12 to -11.77;  = 0.440; random-effects model).

Conclusions: Overall, IBS patients may benefit from vitamin D supplementation to reduce the GI symptoms.

Factors associated with receiving a Functional Disorder diagnostic label: A systematic review.

PLoS One

January 2025

Interdisciplinary Centre Psychopathology and Emotion Regulation, University Medical Center Groningen, University of Groningen, Groningen, the Netherlands.

Objectives: Functional Disorders (FD) are highly prevalent conditions that are diagnosed based on the presence of specific patterns of somatic symptoms. Examples of FDs include Fibromyalgia and Irritable Bowel Syndrome. Many patients who meet the criteria do not receive a formal diagnostic label.

Protease-activated receptor 2 (PAR2) is a central regulator of intestinal barrier function, inflammation and pain. Upregulated intestinal proteolysis and PAR2-signaling are implicated in inflammatory bowel diseases (IBDs) and irritable bowel syndrome (IBS). To identify potential bacterial regulators of PAR2 activity, we developed a functional assay for PAR2 processing and used it to screen conditioned media from a library of diverse gut commensal microbes.

Efficacy of vagus nerve stimulation in gastrointestinal disorders: a systematic review.

Gastroenterol Rep (Oxf)

January 2025

Department of Gastroenterology-Hepatology, NUTRIM Institute of Nutrition and Translational Research in Metabolism, Maastricht University Medical Center, Maastricht, The Netherlands.

Dysfunction of the vagus nerve has been suggested as a contributing factor in various gastrointestinal disorders, prompting interest in vagus nerve stimulation (VNS) as a non-pharmacological therapy. We performed a systematic review to determine the efficacy of invasive and non-invasive VNS in gastrointestinal disorders, including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), functional dyspepsia (FD), functional constipation, gastroesophageal reflux disease, and gastroparesis. We applied a systematic search of the literature in the PubMed, Embase, Web of Science, and Cochrane Library databases in order to identify studies comparing VNS with an adequate control condition (sham stimulation) in patients with gastrointestinal disorders.

Introduction: Non-Celiac Gluten Sensitivity (NCGS) is a common disorder characterized by symptoms resembling those of irritable bowel syndrome. In recent years there has been progress in the understanding of the pathogenic pathways and data suggest that NCGS has a distinct immunological profile that differs from celiac disease (CeD). This has fostered the search for a specific biomarker of NCGS.

Background: Low-dose amitriptyline, a tricyclic antidepressant (TCA), was superior to placebo for irritable bowel syndrome (IBS) in the AmitripTyline at Low-dose ANd Titrated for Irritable bowel syndrome as Second-line treatment (ATLANTIS) trial.

Objective: To perform post hoc analyses of ATLANTIS for predictors of response to, and tolerability of, a TCA.

Design: ATLANTIS randomised 463 adults with IBS to amitriptyline (232) or placebo (231).
