Scand J Gastroenterol 2024; 59:632-638. [PMID: 38557218 DOI: 10.1080/00365521.2024.2328590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 03/04/2024] [Indexed: 04/04/2024]
Abstract
OBJECTIVES Irritable bowel syndrome (IBS) is a common functional gastrointestinal condition. A respectful patient-doctor relationship with good communication is crucial for optimal treatment. Q-methodology is a combination of qualitative and quantitative methods used to study subjectivity. The aim of this study was to compare viewpoints on IBS between patients with IBS and general practitioners (GPs). METHODS We conducted a Q-methodology study by including 30 patients and 30 GPs. All participants were asked to complete Q- sorting of 66 statements on IBS using an online software program. Data were processed using factor analysis. In addition, 3 patients and 3 GPs were interviewed. RESULTS Three factors were extracted from both groups: Patient Factor 1 'Question the diagnosis of IBS', Patient Factor 2 'Lifestyle changes for a physical disorder', Patient Factor 3 'Importance of a diagnosis', GP Factor 1 'Unknown causes of great suffering', GP Factor 2 'Lifestyle changes are important, stress makes IBS worse', GP Factor 3 'Recognized the way IBS affects patients'. There was a strong and statistically significant correlation between patient Factor 1 and GP Factor 1, with a Pearson's r of 0.81 (p < 0.001). Correlations between other factors varied. CONCLUSIONS There was consensus between patients and GPs that IBS is a physical and not a psychiatric disorder of unknown etiology. They also seemed to agree that IBS has a great negative impact on patients' lives and that lifestyle changes are beneficial. There were conflicting opinions regarding gender, cultural factors and the use of antidepressants.

Abstract
BACKGROUND Limited information is available about patterns of healthcare utilization for prevalent gastrointestinal conditions and their link to symptom burden. AIM To identify patterns of healthcare utilization among outpatients with highly prevalent gastrointestinal conditions and define the link between healthcare utilization, symptom burden, and disease group. METHODS We randomly selected patients from the gastroenterology outpatient clinic at Princess Alexandra Hospital who had chronic gastrointestinal conditions such as constipation-predominant irritable bowel syndrome (IBS-C, n = 101), diarrhea-predominant IBS (IBS-D, n = 101), mixed IBS (n = 103), inflammatory bowel disease with acute flare (n = 113), IBD in remission (n = 103), and gastroesophageal reflux disease (n = 102). All had presented at least 12 months before and had a 12-month follow-up after the index consultation. Healthcare utilization data were obtained from state-wide electronic medical records over a 24-month period. Intensity of gastrointestinal symptoms was measured using the validated Structured Assessment of Gastrointestinal Symptoms (SAGIS) Scale. Latent class analyses (LCA) based on healthcare utilization were used to identify distinct patterns of healthcare utilization among these patients. RESULTS LCA revealed four distinct healthcare utilization patterns across all diagnostic groups: Group A: Emergency department utilizers, Group B: Outpatient focused care utilizers, Group C: Inpatient care utilizers and Group D: Inpatient care and emergency department utilizers. LCA groups with high emergency utilization were characterized by high gastrointestinal symptom burden at index consultation regardless of condition (Mean (standard deviation)) SAGIS score Group A: 24.63 (± 14.11), Group B: 19.18 (± 15.77), Group C: 22.48 (± 17.42), and Group D: 17.59 (± 13.74, p < 0.05). CONCLUSION Distinct healthcare utilization patterns across highly prevalent gastrointestinal conditions exist. Symptom severity rather than diagnosis, likely reflecting unmet clinical need, defines healthcare utilization.

Abstract
Background/Aims The objective of this research is to examine factors related to irritable bowel syndrome (IBS) prevalence in a large population-based study. Methods A cross-sectional study was conducted with participants in the Miyagi part of the Tohoku Medical Megabank Project Community-Based cohort study who completed the Rome II Modular Questionnaire. Multivariate odds ratios (ORs) for the presence of IBS and 95% confidence intervals (95% CIs) for the reference group were calculated for each factor. Additionally, a stratified analysis was performed by sex and age group (20-49 years, 50-64 years, and ≥ 65 years). Results Among 16 252 participants, 3025 (18.6%) had IBS, comprising 750 men (15.5%) and 2275 women (19.9%). Multivariate ORs for the presence of IBS decreased significantly with each year of age (OR, 0.98; 95% CI, 0.98-0.99). Moreover, compared with the reference group, ORs for the presence of IBS were significantly higher in individuals whose home was partially damaged by the Great East Japan Earthquake, those with < 16 years of education, those who spent less time walking, those with high perceived stress (1.77, 1.57-2.01), those with high psychological distress (1.58, 1.36-1.82), and those with high symptoms of depression (1.76, 1.60-1.94). In stratified analyses, a significant relationship was found between psychological factors and IBS prevalence in all sex and age groups. Conclusions This large cross-sectional population-based cohort study identified several factors associated with IBS prevalence. Psychological factors were significantly associated with IBS prevalence across all age groups and sexes.

Abstract
Introduction: Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction (DGBI), and associated co-morbidities worsen quality of life. Research concerning IBS co-morbidities in different racial/ethnic groups is very sparse. This study aimed to determine the prevalence rates of co-morbidities and possible differences in a multiracial/ethnic IBS cohort. Methods: Based on ICD-9-coded IBS diagnosis, 740 outpatients (≥18 years) were included in this retrospective study at Boston Medical Center. Demographics and ICD-9-coded co-morbidities were extracted from electronic records. Descriptive statistics and multiple logistic regression were used for data analyses. Results: The most prevalent co-morbidities in this IBS cohort included gastroesophageal reflux disorder (GERD) (30%), depression (27%), anxiety (23%), (chronic obstructive pulmonary disease) COPD/asthma (16%), and obesity (10%). GERD was more prevalent in Hispanics and Blacks (p = 0.0005), and non-ulcer dyspepsia (NUD) was more prevalent in Blacks and Asians (p = 0.003). Higher rates of diabetes mellitus type 2 (DMT2) (p = 0.0003) and depression (p = 0.03), but not anxiety (p = 0.9), were present in Blacks and Hispanics. GERD was significantly associated with Hispanics (p = 0.003), dependent on age, overweight, and obesity. NUD was significantly associated with Blacks (p = 0.01) and Asians (p = 0.006), independent of sex, age, and BMI. Cancer of the thyroid, ovaries, and testis occurred at a five-fold higher rate than expected. Conclusions: Significant racial/ethnic differences exist for IBS co-morbidities in this study cohort, including depression, DMT2, GERD, and NUD. Certain cancers were found to be more frequent in this IBS sample as compared with the general population.

Abstract
INTRODUCTION Irritable bowel syndrome (IBS) has a major impact on emotional, social, and professional life. This study aimed to evaluate general life satisfaction, a subjective measure of well-being, in IBS patients, and to determine which factors are associated with higher life satisfaction. METHODS IBS patients (n = 195, mean age 51.4 ± 16.5 years, 73.8% female) recruited from primary and secondary/tertiary care completed questionnaires regarding gastrointestinal symptoms, quality of life, psychological factors, and life satisfaction (Satisfaction With Life Scale, 5 items, range 5-35). A finite mixture model analysis was performed to identify latent classes. Multivariable linear regression was used to identify variables associated with life satisfaction. RESULTS Overall, 71.3% of the patients were satisfied about their life (Satisfaction With Life Scale-score ≥21). Three latent subgroups could be identified with significantly higher life satisfaction in the subgroup with higher mental quality of life, fewer anxiety and depressive symptoms, lower gastrointestinal specific anxiety, and lower gastrointestinal symptom severity, compared with the other 2 groups. Multivariable linear regression showed that higher physical quality of life (B0.168, P < 0.001) and higher mental quality of life (B0.199, P < 0.001) were associated with higher life satisfaction. Using multivariable regression, no significant association was found between gastrointestinal symptom severity and life satisfaction. DISCUSSION Higher physical and mental quality of life, but not gastrointestinal symptom severity, were independently associated with higher general life satisfaction in IBS. These findings reinforce the clinical need in IBS treatment to focus on the full extent of the disorder and not merely on gastrointestinal symptom improvement. ClinicalTrials.gov Identifier: NCT00775060.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by diarrhea or constipation and other symptoms such as pain, bloating, and flatulence. The disease often has a negative effect on quality of life and is also associated with symptoms of anxiety and depression. Pharmacological treatments are not always effective, and complementary and alternative treatments are common. METHODS We conducted a study on a group intervention based on the Ashtanga school of yoga. Fourteen participants (three men, 11 women; average age 51.4, SD = 16) were recruited from primary care, and 10 completed treatment. At pre-measurement, 4 participants had severe, 9 moderate, and 1 mild IBS, according to the IBS-SSS scale. KEY RESULTS The intervention was regarded as credible (CEQ M = 39.2 SD = 8.8), and no serious adverse events were reported. The intervention showed significant effects on all measurements at post, as follows: IBS-SSS PRE (M = 272.0 SD = 75.5); IBS-SSS POST (M = 177.0 SD = 103.5); GSRS-IBS PRE (M = 48.4 SD = 15.9); GSRS-IBS POST (M = 37.4 SD = 12.4); VSI PRE (M = 38.8 SD = 10.0) VSI POST (M = 25.9 SD = 10.1); PHQ12 PRE (M = 10.0 SD = 4.3); PHQ12 POST (M = 6.9 SD = 4.3); HADS anxiety PRE (M = 8.9 SD = 5.0) HADS anxiety POST (M = 5.7 SD = 3.3) HADS depression PRE (M = 5.6 SD = 3.2) HADS depression POST (M = 3.8 SD = 2.9) IBS-QOL PRE (M = 64.5 SD = 12.5) IBS-QOL POST (M = 72.3 SD = 10.0). The effects were maintained at follow-up, except for general anxiety and depression. Preliminary effects at 3-month follow-up were in the moderate to large range for main outcomes. CONCLUSION & INFERENCES A 10-week group Ashtanga intervention was a feasible intervention for participants with IBS. Preliminary effects were promising and should be explored further in a randomized trial.

Abstract
BACKGROUND Gut-directed hypnotherapy is effective for patients with irritable bowel syndrome (IBS). Despite its considerable evidence base, gut-directed hypnotherapy is not widely available and remains a limited resource. This emphasises the need to select patients who are most likely to benefit. AIM To determine whether baseline patient characteristics were predictive of response to gut-directed hypnotherapy in patients with IBS METHODS: We conducted a secondary analysis of outcomes of 448 patients with refractory Rome III IBS who participated in a randomised study confirming non-inferiority of 6 compared to 12 sessions of gut-directed hypnotherapy. We compared baseline patient characteristics, including age, sex, IBS subtype, quality of life and IBS-Symptom Severity Scale (IBS-SSS), non-colonic symptom score and Hospital Anxiety and Depression (HAD) score between responders and non-responders. We defined response as ≥50-point decrease in IBS-SSS or ≥30% reduction in pain severity scores. RESULTS Overall, 76.3% achieved ≥50-point decrease in IBS-SSS. Responders had a higher baseline non-colonic symptom score (p = 0.005). Those who achieved ≥30% improvement in abdominal pain scores (59.8%) had higher baseline IBS-SSS (p = 0.03), and lower baseline HAD-depression score (p = 0.012). Fifty-four patients (12%) dropped out of gut-directed hypnotherapy. Compared to completers, dropouts had higher baseline HAD-anxiety score (p = 0.034). CONCLUSIONS These data suggest that patients with a higher burden of gastrointestinal and extraintestinal symptoms are most likely to benefit from gut-specific behavioural intervention for refractory IBS. Clinical assessment of gastrointestinal, somatic and psychological symptom profiles may play a role in selecting patients for gut-directed hypnotherapy.

Microbiota-derived butyrate dampens linaclotide stimulation of the guanylate cyclase C pathway in patient-derived colonoids. Neurogastroenterol Motil 2023; 35:e14681. [PMID: 37736865 PMCID: PMC10841278 DOI: 10.1111/nmo.14681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 06/25/2023] [Accepted: 08/29/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND & AIMS Disorders of gut-brain interaction (DGBI) are complex conditions that result in decreased quality of life and a significant cost burden. Linaclotide, a guanylin cyclase C (GCC) receptor agonist, is approved as a DGBI treatment. However, its efficacy has been limited and variable across DGBI patients. Microbiota and metabolomic alterations are noted in DGBI patients, provoking the hypothesis that the microbiota may impact the GCC response to current therapeutics. METHODS Human-derived intestinal organoids were grown from pediatric DGBI, non-IBD colon biopsies (colonoids). Colonoids were treated with 250 nM linaclotide and assayed for cGMP to develop a model of GCC activity. Butyrate was administered to human colonoids overnight at a concentration of 1 mM. Colonoid lysates were analyzed for cGMP levels by ELISA. For the swelling assay, colonoids were photographed pre- and post-treatment and volume was measured using ImageJ. Principal coordinate analyses (PCoA) were performed on the Bray-Curtis dissimilarity and Jaccard distance to assess differences in the community composition of short-chain fatty acid (SCFA) producing microbial species in the intestinal microbiota from pediatric patients with IBS and healthy control samples. KEY RESULTS Linaclotide treatment induced a significant increase in [cGMP] and swelling of patient-derived colonoids, demonstrating a human in vitro model of linaclotide-induced GCC activation. Shotgun sequencing analysis of pediatric IBS patients and healthy controls showed differences in the composition of commensal SCFA-producing bacteria. Butyrate exposure significantly dampened linaclotide-induced cGMP levels and swelling in patient-derived colonoids. CONCLUSIONS & INFERENCES Patient-derived colonoids demonstrate that microbiota-derived butyrate can dampen human colonic responses to linaclotide. This study supports incorporation of microbiota and metabolomic assessment to improve precision medicine for DGBI patients.

Abstract
Opioid-dependent immune-mediated analgesic effects have been broadly reported upon inflammation. In preclinical mouse models of intestinal inflammatory diseases, the local release of enkephalins (endogenous opioids) by colitogenic T lymphocytes alleviate inflammation-induced pain by down-modulating gut-innervating nociceptor activation in periphery. In this study, we wondered whether this immune cell-derived enkephalin-mediated regulation of the nociceptor activity also operates under steady state conditions. Here, we show that chimeric mice engrafted with enkephalin-deficient bone marrow cells exhibit not only visceral hypersensitivity but also an increase in both epithelial paracellular and transcellular permeability, an alteration of the microbial topography resulting in increased bacteria-epithelium interactions and a higher frequency of IgA-producing plasma cells in Peyer's patches. All these alterations of the intestinal homeostasis are associated with an anxiety-like behavior despite the absence of an overt inflammation as observed in patients with irritable bowel syndrome. Thus, our results show that immune cell-derived enkephalins play a pivotal role in maintaining gut homeostasis and normal behavior in mice. Because a defect in the mucosal opioid system remarkably mimics some major clinical symptoms of the irritable bowel syndrome, its identification might help to stratify subgroups of patients.

Abstract
Irritable bowel syndrome (IBS) is one of the most prevalent functional gut disorders in the world. Partially hydrolyzed guar gum, a low-viscosity soluble fiber, has shown promise in the management of IBS-related symptoms. In this study, we aimed to determine if an individual's baseline gut microbiota impacted their response to a partially hydrolyzed guar gum intervention. Patients diagnosed with IBS undertook a 90-day intervention and follow-up. IBS symptom severity, tolerability, quality-of-life, and fecal microbiome composition were recorded during this study. Patients with normal microbiota diversity (Shannon index ≥ 3) showed significant improvements to IBS symptom scores, quality-of-life, and better tolerated the intervention compared to patients with low microbiota diversity (Shannon index < 3). Our findings suggest that an individual's baseline microbiome composition exerts a substantial influence on their response to fiber intervention. Future investigations should explore a symbiotic approach to the treatment of IBS.

Abstract
BACKGROUND Low anterior resection syndrome (LARS) is a well-described consequence of rectal cancer treatment. Studying the degree to which bowel dysfunction exists in the general population may help to better interpret to what extent LARS is related to disease and/or cancer treatment. Currently, North American LARS normative data are lacking. The aim of this study was to describe the prevalence of bowel dysfunction, as measured by the LARS score, and quality of life (QoL) in a reference North American sample. Quality of life was measured and associations between participant characteristics and LARS were identified. STUDY DESIGN This was a single-institution cross-sectional study of asymptomatic adults who underwent screening and surveillance colonoscopies from 2018 to 2021 with no/benign endoscopic findings. Survey was conducted on select comorbidities, sociodemographic factors, LARS, and QoL. Outcomes were LARS and QoL. Multivariable linear regression accounting for a priori clinical factors associated with bowel dysfunction was performed. RESULTS Of 1,004 subjects approached, 502 (50.0%) participated, and 135 (26.9%) participants had major/minor LARS. On multiple linear regression, female sex (β = 2.15, 95% CI 0.30 to 4.00), younger age (β = -0.10, 95% CI -0.18 to -0.03), White ethnicity (β = 2.45, 95% CI 0.15 to 4.74), and the presence of at least one of the following factors: diabetes, depression, neurologic disorder, or cholecystectomy (β = 3.54, 95% CI 1.57 to 5.51) were independently associated with a higher LARS score. Individuals with LARS had lower global QoL, functional subscales, and various symptom subscale scores. CONCLUSIONS Our study identified the baseline prevalence of LARS in asymptomatic adults who have not undergone a low anterior resection. These normative data will allow for more accurate interpretation of ongoing studies on LARS in North American rectal cancer patients.

Abstract
Background Irritable bowel syndrome (IBS) is a brain-gut disorder with high global prevalence, resulting from abnormalities in brain connectivity of the default mode network and aberrant changes in gray matter (GM). However, the findings of previous studies about IBS were divergent. Therefore, we conducted a meta-analysis to identify common functional and structural alterations in IBS patients. Methods Altogether, we identified 12 studies involving 194 IBS patients and 230 healthy controls (HCs) from six databases using whole-brain resting state functional connectivity (rs-FC) and voxel-based morphometry. Anisotropic effect-size signed differential mapping (AES-SDM) was used to identify abnormal functional and structural changes as well as the overlap brain regions between dysconnectivity and GM alterations. Results Findings indicated that, compared with HCs, IBS patients showed abnormal rs-FC in left inferior parietal gyrus, left lingual gyrus, right angular gyrus, right precuneus, right amygdala, right median cingulate cortex, and left hippocampus. Altered GM was detected in the fusiform gyrus, left triangular inferior frontal gyrus (IFG), right superior marginal gyrus, left anterior cingulate gyrus, left rectus, left orbital IFG, right triangular IFG, right putamen, left superior parietal gyrus and right precuneus. Besides, multimodal meta-analysis identified left middle frontal gyrus, left orbital IFG, and right putamen as the overlapped regions. Conclusion Our results confirm that IBS patients have abnormal alterations in rs-FC and GM, and reveal brain regions with both functional and structural alterations. These results may contribute to understanding the underlying pathophysiology of IBS. Systematic review registration https://www.crd.york.ac.uk/prospero, identifier CRD42022351342.

Abstract
Gut microbiota and short-chain fatty acids (SCFAs) are recognized as key factors in the pathophysiology of irritable bowel syndrome. Astaxanthin is a carotenoid with strong antioxidant and anti-inflammatory activities. In this study, we examined the effects of astaxanthin on gut microbiota-, SCFAs-, and corticotropin-releasing factor (CRH)-induced intestinal hypermotility. Male Wistar rats (n=12 per group) were fed a diet with or without 0. 02% (w/w) astaxanthin for four weeks and CRH or saline was administered intravenously. The number of fecal pellets was counted 2 h after injection. Then the rats were sacrificed, and the cecal content were collected 3 h after injection. The number of feces was significantly increased by CRH injection in the control group (2.0 vs. 6.5; p=0.028), but not in the astaxanthin group (1.0 vs. 2.2; p=0.229) (n=6 per group). The cecal microbiota in the astaxanthin group was significantly altered compared with that in the control group. The concentrations of acetic acid (81.1 μmol/g vs. 103.9 μmol/g; p=0.015) and butyric acid (13.4 μmol/g vs. 39.2 μmol/g; p<0.001) in the astaxanthin group were significantly lower than that in the control group (n=12 per group). Astaxanthin attenuates CRH-induced intestinal hypermotility and alters the composition of gut microbiota and SCFAs.

Abstract
Diabetic gastroparesis (DG) is one of the many complications of diabetes mellitus (DM). Even though this condition surfaces years after uncontrolled disease, it affects the quality of life in several ways and causes significant morbidity. Common symptoms experienced by the patients include postprandial nausea, vomiting, abdominal fullness, and pain. Strict glycemic control is essential to evade the effects of DG. The purpose of this review article is to briefly study the pathophysiology, clinical features, diagnostic modalities, and the effects of DG on different aspects of life. Furthermore, it also focuses on the emerging treatment modalities for DG. Tradipitant and relamorelin are two such treatment options that are gaining noteworthy recognition and are discussed in detail in this review article. As observed through various clinical trials, these drugs help alleviate symptoms like nausea, vomiting, abdominal pain, and bloating in patients suffering from DG, thereby targeting the most common and bothersome symptoms of the disease. This leads to an improvement in the quality of life, making it a reliable treatment option for this disease. But while pharmacological intervention is vital, psychological support and lifestyle changes are equally important and are the reason why a multidisciplinary approach is required for the treatment of DG.

Abstract
Irritable bowel syndrome (IBS) affects 5-10% of the global population. Up to one-third of people with IBS also experience anxiety or depression. Gastrointestinal and psychological symptoms both drive health-care use in people with IBS, but psychological comorbidity seems to be more important for long-term quality of life. An integrated care approach that addresses gastrointestinal symptoms with nutrition and brain-gut behaviour therapies is considered the gold standard. However, best practice for the treatment of individuals with IBS who have a comorbid psychological condition is unclear. Given the rising prevalence of mental health disorders, discussion of the challenges of implementing therapy for people with IBS and anxiety and depression is critical. In this Review, we draw upon our expertise in gastroenterology, nutrition science and psychology to highlight common challenges that arise when managing patients with IBS and co-occurring anxiety and depression, and provide recommendations for tailoring clinical assessment and treatment. We provide best practice recommendations, including dietary and behavioural interventions that could be applied by non-specialists and clinicians working outside an integrated care model.

Abstract
AIM To explore the perspectives, experience, and concerns of patients with irritable bowel syndrome (IBS) in China. METHODS We used data mining to investigate posts shared in Baidu Tieba concerned with IBS; we collected the data through the crawler code, and mined the cleaned data's themes based on Latent Dirichlet allocation (LDA) and the Grounded theory. RESULTS We found 5746 network posts related to IBS. LDA analysis generated 20 topics, and grounded theory analysis established eight topics. Combining the two methods, we finally arranged the topics according to five concepts: difficulty in obtaining disease information; serious psychosocial problems; dissatisfied with the treatment; lack of social support; and low quality of life. CONCLUSION Social media research improved patient-centric understanding of patients' experiences and perceptions. Our study may facilitate doctor-patient communication and assist in the formulation of medical policies.

Effectiveness of Osteopathic Manipulative Treatment in Adults with Irritable Bowel Syndrome: A Systematic Review and Meta-Analysis. Healthcare (Basel) 2023; 11:2442. [PMID: 37685480 PMCID: PMC10487478 DOI: 10.3390/healthcare11172442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 08/27/2023] [Accepted: 08/28/2023] [Indexed: 09/10/2023] Open
Abstract
The aim of this systematic review and meta-analysis was to evaluate the effectiveness of the osteopathic manipulative treatment (OMT) in adults with irritable bowel syndrome (IBS). A literature resview was carried out on the following databases: PubMed, Embase, Cochrane, Cinahl, Scopus, PEDro and ClinicalTrials.gov. 350 articles were recovered. Eligibility criteria were evaluated by two independent reviewers, including randomized controlled trials (RCTs), quasi-RCTs, or ongoing RCTs with OMT compared to any kind of control in patients diagnosed with IBS. Six studies (five RCTs and one ongoing RCT) were considered eligible. Four RCTs were classified as some concerns and one as high risk of bias. In the meta-analysis, OMT compared to sham/no intervention showed statistically significant results for abdominal pain (effect size ES = -1.14 [-1.66, -0.62]; p < 0.0001) and constipation (ES = -0.66 [-1.12, -0.20]; p = 0.005). Instead, OMT was not superior to the control for the IBS symptoms measured with the IBS Severity Score and the Likert scale (ES = -0.34 [-0.83, 0.16]; p = 0.19), and diarrhea (ES = -1.20 [-2.84, 0.43]; p = 0.15). The quality of evidence was "low" for IBS symptoms in general for abdominal pain and constipation, while it was judged as "very low" for diarrhea. OMT turns out to be safe in the treatment of IBS without major adverse effects. OMT may be effective in IBS patients, however the results must be interpreted carefully due to the low methodological quality of the studies.

Abstract
Many veterans deployed to Gulf War areas suffer from persistent chronic diarrhea that is disabling and affects their quality of life. The causes for this condition have eluded investigators until recently and recent literature has shed light on the effect of vitamin D on the brain-gut axis. This study focused on determining clinical causes contributing to diarrhea and assessed whether reversing the identified causes, specifically vitamin D deficiency (VDD), could reduce the incidence of diarrhea in Gulf War veterans (GWVs). All patients completed a workup that included serologies (IBD, celiac), routine laboratory tests (CBC, chemistry panels, TSH, T4, CRP), cultures for enteric pathogens (C diff, bacteria, viruses, small intestinal bacterial overgrowth (SIBO)), and upper and lower endoscopies with histology and a trial of cholestyramine to exclude choleretic diarrhea and rifaximin for dysbiosis. A total of 4221 veterans were screened for chronic diarrhea, yielding 105 GWVs, of which 69 GWVs had irritable bowel syndrome with diarrhea (IBS-D). Paired t-tests demonstrated that all GWVs had VDD (t-11.62, df68 and sig(2-tailed) 0.0001) (defined as a vitamin D level less than 30 ng/mL with normal ranges of 30-100 ng/mL) but no positive serologies, inflammatory markers, abnormal endoscopies, cultures, or histology to explain their persistent diarrhea. There was no correlation with age, BMI, or inflammation. Some zip codes had a higher frequency of GWVs with VDD, but the number of deployments had no impact. Treatment with vitamin D supplementation (3000-5000 units), given in the morning, based on weight, reduced the number of bowel movements per day (p < 0.0001) without causing hypercalcemia. We suggest that VDD is important in the etiology of IBS-D in GWVs and that vitamin D supplementation significantly reduces diarrhea.

Abstract
Endometriosis and irritable bowel syndrome (IBS) are chronic conditions affecting up to 10% of the global population, imposing significant burdens on healthcare systems and patient quality of life. Interestingly, around 20% of endometriosis patients also present with symptoms indicative of IBS. The pathogenesis of both these multifactorial conditions remains to be fully elucidated, but connections to gut microbiota are becoming more apparent. Emerging research underscores significant differences in the gut microbiota composition between healthy individuals and those suffering from either endometriosis or IBS. Intestinal dysbiosis appears pivotal in both conditions, exerting an influence via similar mechanisms. It impacts intestinal permeability, triggers inflammatory reactions, and initiates immune responses. Furthermore, it is entwined in a bidirectional relationship with the brain, as part of the gut-brain axis, whereby dysbiosis influences and is influenced by mental health and pain perception. Recent years have witnessed the development of microbiota-focused therapies, such as low FODMAP diets, prebiotics, probiotics, antibiotics, and fecal microbiota transplantation, designed to tackle dysbiosis and relieve symptoms. While promising, these treatments present inconsistent data, highlighting the need for further research. This review explores the evidence of gut dysbiosis in IBS and endometriosis, underscoring the similar role of microbiota in both conditions. A deeper understanding of this common mechanism may enable enhanced diagnostics and therapeutic advancements.

Abstract
OBJECTIVE Evidence regarding the association between exercise habits and irritable bowel syndrome (IBS) remains scarce in a young population. It is also unknown whether the existence of an exercise partner affects this issue. The purpose of this study was to explore the association between exercise habits that include an exercise partner and IBS in a young Japanese population. METHODS This study enrolled 8923 Japanese university students and examined exercise frequency and intensity, and exercise partners using self-administered questionnaires. IBS and functional dyspepsia were defined according to the Rome III criteria. RESULTS The prevalence of IBS in this survey was 6.5%. Moderate frequency exercise was inversely related with IBS [adjusted odds ratio (aOR): 0.65 (95% confidence interval, CI: 0.51-0.83), P for trend = 0.005]. Moderate and high exercise intensities were independently and inversely related with IBS, respectively [aORs were moderate: 0.76 (95% CI: 0.61-0.95) and high: 0.62 (95% CI: 0.48-0.78), P for trend = 0.001]. Exercising with a group or with friends instead of alone was independently inversely related with IBS [aOR with groups: 0.53 (95% CI: 0.40-0.70) and with friends: aOR 0.71 (95% CI: 0.54-0.93)]. After excluding subjects with overlapping IBS and functional dyspepsia, an inverse association between high intensity of exercise or exercise in a group and IBS remained significant. CONCLUSION The frequency and intensity of exercise may be independently inversely related with IBS in a young Japanese population. Also, exercise with others may be important for preventing IBS.

Abstract
Gut microbiota includes a vast collection of microorganisms residing within the gastrointestinal tract. It is broadly recognized that the gut and brain are in constant bidirectional communication, of which gut microbiota and its metabolic production are a major component, and form the so-called gut microbiome-brain axis. Disturbances of microbiota homeostasis caused by imbalance in their functional composition and metabolic activities, known as dysbiosis, cause dysregulation of these pathways and trigger changes in the blood-brain barrier permeability, thereby causing pathological malfunctions, including neurological and functional gastrointestinal disorders. In turn, the brain can affect the structure and function of gut microbiota through the autonomic nervous system by regulating gut motility, intestinal transit and secretion, and gut permeability. Here, we examine data from the CAS Content Collection, the largest collection of published scientific information, and analyze the publication landscape of recent research. We review the advances in knowledge related to the human gut microbiome, its complexity and functionality, its communication with the central nervous system, and the effect of the gut microbiome-brain axis on mental and gut health. We discuss correlations between gut microbiota composition and various diseases, specifically gastrointestinal and mental disorders. We also explore gut microbiota metabolites with regard to their impact on the brain and gut function and associated diseases. Finally, we assess clinical applications of gut-microbiota-related substances and metabolites with their development pipelines. We hope this review can serve as a useful resource in understanding the current knowledge on this emerging field in an effort to further solving of the remaining challenges and fulfilling its potential.

Abstract
BACKGROUND Olorinab is a highly selective, peripherally acting, full agonist of cannabinoid receptor 2. This study assessed the efficacy and safety of olorinab to treat abdominal pain in patients with irritable bowel syndrome with diarrhea (IBS-D) and constipation (IBS-C). METHODS CAPTIVATE was a phase 2b, randomized, double-blind, placebo-controlled, parallel-group trial. Eligible participants aged 18-70 years with IBS-C and IBS-D diagnosed per Rome IV received olorinab 10 mg, 25 mg, or 50 mg three times daily (TID) or placebo TID for 12 weeks. The primary endpoint was the change in patient-reported average abdominal pain score (AAPS) from baseline to Week 12. KEY RESULTS A total of 273 participants were randomized to receive olorinab 10 mg (n = 67), olorinab 25 mg (n = 67), olorinab 50 mg (n = 69), or placebo (n = 70). Although a treatment response was observed across all groups, the weekly change in average AAPS from baseline to Week 12 was not significantly different between placebo and any olorinab dose. In a prespecified subgroup analysis of participants with a baseline AAPS ≥6.5, olorinab 50 mg (n = 35) significantly improved AAPS compared with placebo (n = 30) (p = 0.014). Adverse event rates were comparable between olorinab and placebo and there were no reported serious adverse events or deaths. CONCLUSION AND INFERENCES Although olorinab was well-tolerated and improved weekly AAPS, the primary endpoint was not met. However, in participants with moderate-to-severe pain at baseline (AAPS ≥6.5), olorinab 50 mg significantly improved weekly AAPS compared with placebo. CLINICALTRIALS gov: NCT04043455.

Abstract
BACKGROUND AND AIM Diet is a major contributor to irritable bowel syndrome (IBS) and is also a powerful tool for treatment of IBS. This study compared two diets and explored the effectiveness of the diets when combined with a probiotic for treatment of IBS-D patients. METHODS Phase I, patients were randomized into groups; control, cold/spicy/fried restricted diet (CSF res diet), IgG positive restricted diet (IgG res diet), and a combination both diets (CSF + IgG res diet). Phase II, patients were randomized into IgG res diet + placebo and IgG res diet + probiotic. Both interventions were 12 weeks in duration. Symptom Severity Scale (IBS-D-SSS) and IgG titer were assessed at the beginning and the end of the study. RESULTS Totals of 214 and 167 patients completed the two parts of the study, respectively. After intervention, IBS-D-SSS and TIgG grade were significantly improved compared to baseline, with results similar to the control group. In general, there were decreases in IBS-D-SSS and TIgG grade that were significantly different among the groups. There were exceptions; no differences were observed for IBS-D-SSS between the IgG res diet and CSF + IgG res diet, or TIgG grade between the CSF res diet, IgG res diet, and CSF + IgG res diet. However, the CSF res diet and IgG res diet had a synergistic effect that decreased IBS-D-SSS and TIgG titer, with a greater contribution by the IgG res diet. Therefore, we evaluated the IgG res diet with either placebo or probiotic and found that IBS-D-SSS and TIgG grade decreased from baseline. There was a significant decrease in IBS-D-SSS with the probiotic but TIgG grade was not significantly different between the IgG diet + placebo and IgG diet + probiotic diet. CONCLUSIONS Both the CSF res diet and IgG res diet improved IBS symptoms and demonstrated synergy, although the IgG res diet had a greater contribution. Further, when intolerant foods cannot be eliminated from a diet, avoiding uncooked, cold, spicy, fried, and alcoholic foods is a superior choice. The IgG res diet combined with Bifidobacteria was the best dietary choice and may function though a non-IgG pathway.

[PMID: 37096309 PMCID: PMC10125791 DOI: 10.3346/jkms.2023.38.e126] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 01/06/2023] [Indexed: 04/26/2023] Open
Abstract
BACKGROUND The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors' perceptions of the disease, and treatment patterns. METHODS From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. RESULTS A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome. Several differences were noted between the primary, secondary, and tertiary physicians' groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. 'The patient did not adhere to the diet' as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and 'There are individual differences in terms of effectiveness' was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. CONCLUSION Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.

[PMID: 37018426 DOI: 10.1111/nmo.14578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/08/2023] [Accepted: 03/14/2023] [Indexed: 04/07/2023]
Abstract
BACKGROUND Previous epidemiologic studies in Sweden have only covered some of the disorders of gut-brain interaction (DGBI) and are not representative of the general population. This study aimed to define the prevalence and impact of DGBI in Sweden. METHODS We used Swedish data from the Rome Foundation Global Epidemiology Study which include information on DGBI diagnoses, psychological distress, quality of life (QoL), healthcare utilization, and the impact of stress on GI symptoms. KEY RESULTS The prevalence of having any DGBI was 39.1% (95% CI 37.0-41.2); esophageal disorders 6.1% (5.1-7.3), gastroduodenal disorders 10.7% (9.3-12.0), bowel disorders 31.6% (29.6-33.6), and anorectal disorders 6.0% (5.1-7.2). Subjects with a DGBI more commonly reported anxiety and/or depression, reduced mental and physical QoL, and more frequent doctor visits due to health problems. Subjects with a DGBI reported bothersome gastrointestinal (GI) symptoms to a greater extent and more than 1/3 had visited a doctor due to GI problems and of those 1/3 had seen multiple doctors. Prescription medications were available among 36.4% (31.0-42.0) who had bothersome GI symptoms and a DGBI, with sufficient symptom relief in 73.2% (64.0-81.1). Psychological factors and eating were reported to worsen GI symptoms and stress during the last month was greater in subjects with a DGBI. CONCLUSIONS AND INFERENCES DGBI prevalence and its impact in Sweden is in line with global data, including increased healthcare utilization. GI symptoms are commonly affected by psychological factors and eating, and a high proportion of those on prescription medication report sufficient GI symptom relief.

A systematic review, pairwise meta-analysis and network meta-analysis of randomized controlled trials exploring the role of fecal microbiota transplantation in irritable bowel syndrome. Eur J Gastroenterol Hepatol 2023; 35:471-479.

Abstract
BACKGROUND Treatment is a challenge in Irritable Bowel Syndrome (IBS) and fecal microbiota transplantation (FMT) has attracted significant interest. Network meta-analysis (NWM) has been established as an evidence-synthesis tool that incorporates direct and indirect evidence in a collection of randomized controlled trials (RCTs) comparing therapeutic intervention competing for similar therapeutic results. No NWM exists concerning the comparative effectiveness and safety of various FMT modalities for IBS. AIM We updated pairwise meta-analyses published in the past and assessed the comparative effectiveness and safety of various FMT delivery modalities for IBS. METHODS Pairwise meta-analyses and Bayesian NWM were performed. Heterogeneity, consistency of results and publication bias were explored. RESULTS Of 510 titles raised by initial search, seven RCTs were entered into meta-analyses and NWM. They included 470 patients and controls, in whom four FMT delivery modalities were used, that is via colonoscopy, nasojejunal tube, duodenoscope and capsules per os. In the pairwise meta-analysis, the pooled results showed that overall FMT was not superior to placebo, whereas the subgroup analyses showed that FMT via duodenoscope and nasojejunal tube was superior. The NWM showed that 60-g FMT via duodenoscope had the highest efficacy (OR, 26.38; 95% CI, 9.22-75.51) and was by far the highest in the efficacy ranking (SUCRA, 98.8%). CONCLUSION The pooled results showed no overall advantage of FMT over placebo in IBS. However, upper GI delivery (via duodenoscopy or nasojejunal tube) proved to be effective. Consequently, well-designed RCTs are needed to ensure the efficacy and safety profile before FMT can be applied in everyday clinical practice for IBS patients.

Abstract
BACKGROUND A frequent, although not universal, feature of irritable bowel syndrome (IBS) is heightened sensitivity to mechanical stimulation of the rectum, termed rectal hypersensitivity (RH). Differences in RH-based on sex, IBS subtype, IBS diagnostic criteria and age of population studied are incompletely understood. We aimed to determine whether IBS population had lower pain thresholds than healthy controls. METHODS We searched MEDLINE and EMBASE databases (1970-2021). Prospective studies that compared pain/discomfort thresholds to mechanical rectal stimuli in IBS and healthy controls were included. Data were pooled for meta-analyses and effect sizes were calculated with 95% confidence interval (CIs). RESULTS Our search strategy identified 809 studies of which 32 studies met the inclusion criteria. Reduced rectal pain thresholds was more common in IBS patients compared to healthy controls with an effect size of 1.00 95% CIs (0.77-1.24) (p < 0.0001) (I2 = 78.6%). The pediatric IBS population had lower pain thresholds than adult IBS populations (p = 0.05) but no difference based on IBS diagnostic criteria, subtype or sex. CONCLUSION & INFERENCES The results suggest that reduced rectal pain threshold to experimental stimulation is far more common in IBS patients than healthy controls. Further research is required to understand the pathophysiological and therapeutic implications of rectal sensitivity such as its role in measuring response to treatment and prognosis in IBS.

Abstract
BACKGROUND & AIMS This study used the database from the Rome Foundation Global Epidemiology Survey to assess the differences in quality of life overall, and by age and sex, across individual disorders of gut-brain interaction (DGBI), gastrointestinal anatomical region(s), and number of overlapping DGBI. METHODS Data were collected via the Internet in 26 countries, using the Rome IV diagnostic questionnaire and a supplemental questionnaire including the Patient-Reported Outcomes Measurement Information Systems Global-10 quality of life measure. Factorial analyses of variance were used to explore physical and mental quality of life, adjusting for multiple comparisons. RESULTS Among the 54,127 respondents, quality of life deteriorated significantly with increasing number of overlapping DGBI, with respondents reporting ≥2 DGBI having significantly poorer quality of life than those with only 1 DGBI or those without any DGBI. Men with DGBI reported better quality of life than women, and those aged ≥65 years reported better quality of life than those <65 years. Age, sex, number of overlapping DGBI, somatization, anxiety, depression, and functional experiences (concern, embarrassment, or stress associated with bowel functioning) relating to DGBI, were significant predictors of poorer physical and mental quality of life. CONCLUSIONS This study is the most comprehensive assessment of quality of life to date in adults living with a DGBI. It provides a representative picture of DGBI impact on adults in the global adult population and highlights the significant detrimental impact of living with a DGBI on quality of life.

Positive psychological well-being: A novel concept for improving symptoms, quality of life, and health behaviors in irritable bowel syndrome. Neurogastroenterol Motil 2023; 35:e14531. [PMID: 36650705 PMCID: PMC10033392 DOI: 10.1111/nmo.14531] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 01/01/2023] [Indexed: 01/19/2023]
Abstract
BACKGROUND Though a growing body of research suggests that greater positive psychological well-being in irritable bowel syndrome (IBS) may be protective, existing brain-gut behavior therapies primarily target negative psychological factors. Little is known about how positive psychological factors in IBS relate to IBS symptoms, health-related quality of life (HRQoL), or adherence to key health behaviors, such as physical activity and diet modification. Accordingly, per the ORBIT model of behavioral treatment development for chronic diseases, we explored potential connections between psychological constructs and IBS symptoms, health behavior engagement (physical activity and dietary modification), and HRQoL in a qualitative study to inform the development of a novel brain-gut behavior therapy. METHODS Participants with IBS completed self-report assessments and semi-structured phone interviews about relationships between positive and negative psychological constructs, IBS symptoms, health behavior engagement, and HRQoL. KEY RESULTS Participants (n = 23; 57% female) ranged in age from 25 to 79 (mean age = 54). IBS subtypes were similarly represented (IBS-diarrhea [n = 8], IBS-constipation [n = 7], and IBS-mixed [n = 8]). Participants described opposing relationships between positive and negative psychological constructs, IBS symptoms, health behavior engagement, and HRQoL, respectively, such that experiencing positive constructs largely mitigated IBS symptoms, boosted health behavior participation, and improved HRQoL, and negative constructs exacerbated symptoms, reduced health behavior participation, and worsened HRQoL. CONCLUSIONS AND INFERENCES Participants with IBS linked greater positive psychological well-being to moderated IBS symptoms and better HRQoL and health behavior participation. An intervention to cultivate greater well-being may be a novel way to mitigate IBS symptoms, boost health behavior participation, and improve HRQoL in IBS.

Abstract
In recent years, there has been a growing interest in a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) as a promising therapeutic approach to reduce the symptoms associated with irritable bowel syndrome (IBS). Hence, the development of low FODMAPs products is an important challenge for the food industry, and among the various foodstuffs associated with the intake of FODMAPs, cereal-based products represent an issue. In fact, even if their content in FODMAPs is limited, their large use in diet can be an important factor in developing IBS symptoms. Several useful approaches have been developed to reduce the FODMAPs content in processed food products. Accurate ingredient selection, the use of enzymes or selected yeasts, and the use of fermentation steps carried out by specific lactic bacteria associated with the use of sourdough represent the technical approaches that have been investigated, alone or in combination, to reduce the FODMAPs content in cereal-based products. This review aims to give an overview of the technological and biotechnological strategies applicable to the formulation of low-FODMAPs products, specifically formulated for consumers affected by IBS. In particular, bread has been the foodstuff mainly investigated throughout the years, but information on other raw or processed products has also been reported. Furthermore, taking into account the required holistic approach for IBS symptoms management, in this review, the use of bioactive compounds that have a positive impact on reducing IBS symptoms as added ingredients in low-FODMAPs products is also discussed.

Abstract
BACKGROUND Little is known about associations with reduced quality of life in irritable bowel syndrome (IBS) or impact of IBS on quality of life compared with other chronic conditions. METHODS We collected demographic, gastrointestinal and psychological symptoms, healthcare usage, direct healthcare costs, impact on work and activities of daily living data from 752 individuals with Rome IV-defined IBS. We used the irritable bowel syndrome quality of life (IBS-QOL) and the EQ-5D-5L questionnaires to examine characteristics associated with lower quality of life. RESULTS The mean IBS-QOL among all 752 individuals with Rome IV IBS was 48.4 (SD 22.3) and the mean EQ-5D score was 0.570 (SD 0.283), the latter being comparable to people with stroke, leg ulcers or chronic obstructive pulmonary disease. Lower levels of both disease-specific and generic quality of life were associated with severe IBS symptom scores, abnormal anxiety or depression scores, and higher somatoform symptom-reporting and gastrointestinal symptom-specific anxiety scores (p < 0.001 for all analyses). Those with lower quality of life had significantly higher healthcare usage and direct healthcare costs and more impairment in work and activities of daily living (p < 0.01 for all analyses). Avoidance of alcohol, lower educational level, abnormal anxiety, depression or somatoform symptom-reporting scores, and impairment in social leisure activities, home management or maintaining close relationships were all independently associated with lower quality of life. CONCLUSION IBS has a substantial impact on the quality of life of those affected, and worse than observed in some severe chronic organic conditions.

Abstract
BACKGROUND AND OBJECTIVE National patient registers are valuable in epidemiological studies. To ensure high-quality data for studies of irritable bowel syndrome (IBS), this study aimed to validate the ICD-10 code for IBS in the Swedish National Patient Register. METHODS The positive predictive values (PPV) for IBS defined by the Rome criteria were calculated based on a review of medical records of randomly selected individuals with a first-ever diagnostic listing of IBS in the Swedish National Patient register in the year 2005 (Rome II criteria) or 2010 (Rome III criteria). KEY RESULTS 340 medical records were reviewed (172 from 2005 and 168 from 2010). The majority of patients were females (74%), and the mean age was 42 years. IBS used in any type of department had a PPV of 76% (95% confidence interval 71-80%), which increased to 80% (76-84%) when we included individuals likely to have IBS but where information about some aspects of the Rome criteria was lacking in the medical record. Two highly specialized gastroenterological departments had the best PPV, 96%, while departments of internal medicine in general had a PPV of 82% (80-95%). The PPV for the IBS subtype was 62% (55-67%). The PPVs were not significantly different comparing the two time periods investigated. CONCLUSION AND INFERENCES The validity of a register-based definition of IBS in the Swedish National Patient register is high and can be used to identify patients with IBS in observational research. The data source, i.e., type of hospital and department, influences reliability.

Abstract
Reliable biomarkers for common disorders of gut-brain interaction characterized by abdominal pain, including irritable bowel syndrome (IBS), are critically needed to enhance care and develop individualized therapies. The dynamic and heterogeneous nature of the pathophysiological mechanisms that underlie visceral hypersensitivity have challenged successful biomarker development. Consequently, effective therapies for pain in IBS are lacking. However, recent advances in modern omics technologies offer new opportunities to acquire deep biological insights into mechanisms of pain and nociception. Newer methods for large-scale data integration of complementary omics approaches have further expanded our ability to build a holistic understanding of complex biological networks and their co-contributions to abdominal pain. Here, we review the mechanisms of visceral hypersensitivity, focusing on IBS. We discuss candidate biomarkers for pain in IBS identified through single omics studies and summarize emerging multi-omics approaches for developing novel biomarkers that may transform clinical care for patients with IBS and abdominal pain.

Abstract
Los trastornos gastrointestinales funcionales (tgf) son enfermedades crónicas que configuran un problema relevante en la salud pública, asociados en investigaciones previas a una peor calidad de vida. El objetivo del presente trabajo fue estudiar la calidad de vida en pacientes que acuden a un servicio de neurogastroenterología en un hospital de Argentina ycompararlo con población control. Para ello, se realizó un estudio cuantitativo y transversal incluyendo población clínica diagnosticada con algún tgf (n = 35) y una muestra control sin diagnóstico de tgf (n = 37). Se encontraron diferencias significativas entre personas con tgf y sujetos control, χ² (1, n = 70) = 30.23, p < .001 en todas las subdimensiones de la escala de calidad de vida (mqli), exceptuando satisfacción espiritual (pe). Similar a investigaciones previas, los resultados de este estudio sugieren que, en Argentina —al igual que en otros países—, los individuos con tgf muestran una peorpercepción de calidad de vida que la población general. Estos hallazgos podrían contribuir al diseño de intervenciones que contemplen variables biopsicosociales, con el objetivo de una mejoría integral en la calidad de vida de las personas que padecen estos trastornos.

Abstract
INTRODUCTION Fecal microbiota transplantation (FMT) has been proposed as a potential treatment for irritable bowel syndrome (IBS); however, the consensus regarding its efficacy and safety is limited. MATERIALS AND METHODS We performed a systematic search of the literature using PubMed, EMBASE, Ovid MEDLINE, and Cochrane. Meta-analyses were conducted in relative risk (RR) or standard mean difference (SMD) using 95% confidence intervals (CI). Cochrane risk-of-bias 2 tool (RoB2) was employed to evaluate the study quality. RESULT Of 2,589 potential records, 7 studies with 9 cohorts involving 505 participants were included. Meta-analyses showed no significant difference in the short-term (12 weeks) and long-term (12 months) global improvement of IBS symptoms of FMT vs. placebo (RR 0.63, 95% CI 0.39-1.00 and RR 0.88, 95% CI 0.53-1.45, respectively). There were statistically significant differences of short-term IBS-SSS improvement (SMD -0.58, 95% CI -1.09 to -0.88) and short-term IBS-QoL improvement (SMD 0.67, 95% CI 0.43-0.91). Eight from 9 studies (88.9%) had a low risk of bias. The subgroup analysis revealed the short-term global symptoms improvement in studies with low-risk of bias (RR 0.53, 95% CI 0.35-0.81), studies with well-defined donors (RR 0.31, 95% CI 0.14-0.72), and studies with FMT using colonoscopy (RR 0.66, 95% CI 0.47-0.92). Major FMT adverse events are transient and rapidly self-limiting. CONCLUSION FMT significantly improved IBS-SSS and IBS-QoL in the short-term period in IBS patients. However, global symptom improvement showed no significance. Well-defined donors and appropriate fecal administration routes appear to be important factors for the successful outcomes of FMT in IBS.

Abstract
Introduction Irritable bowel syndrome (IBS) is one of the most prevalent gastrointestinal disorders worldwide. There is still debate about the pathophysiology of IBS. Symptoms of IBS include abdominal pain and alternating bowel movements, but the severity differs among the patients, which affects their quality of life. Our main aim in this study is to find the impact of work hours on the quality of life of adult employees with irritable bowel syndrome in Saudi Arabia. Methods An analytical cross-sectional study was conducted using an online self-administered survey including employees over 18 years old in Saudi Arabia. The survey was designed in three different parts. The first part is demographics and personal information, The second concentrates on IBS using the Rome-IV criteria while the third part reviewed the participant's quality of life by utilizing the quality-of-life scale (QOLS). Results The total number of participants was 1800; most of the population were females (954; 53%) and there were 846 (47%) males. The study showed that 27.11% were diagnosed with IBS. Furthermore, the result revealed significant differences between working hours, with employees who work more than nine hours (33.7%) being more affected by IBS than others. Nevertheless, significant independent risk factors for IBS were QOLS (OR = 0.988; 95% CI (0.981, 0.995), p = .001), being an employee in free business (OR = 1.755; 95% CI (1.134, 2.714) p = .012), working between 6 and 9 hours (OR = 0.623; 95% CI (0.404, 0.961), p = .032). Conclusion The impact of work hours on adult employees with IBS in Saudi Arabia has been noticed; the results showed that the prevalence of IBS among females is higher; employees working more than nine hours with a medium to sedentary work nature are more vulnerable to developing IBS. We suggest that IBS patients should address their needs to their employers.

Abstract
PURPOSE The association between body mass index (BMI) and irritable bowel syndrome (IBS) has been inconsistent in the Asian population. Also, no evidence regarding this issue in the young population exists. The aim of the present study is to investigate the association between BMI and IBS based on the Rome III criteria in young Japanese people. METHODS This study was a cross-sectional study consisted of 8923 Japanese university students. The definition of IBS was based on the Rome III criteria. BMI was divided into four categories (quartiles) on the basis of the study subjects' distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, and overweight was BMI < 18.5 kg/m2, 18.5 ≤ BMI < 25 kg/m2 (reference), and 25 ≤ BMI kg/m2, respectively. Age, sex, drinking, smoking, exercise habit, anemia, and sports injury were selected a priori as potential confounding factors. RESULTS The prevalence of IBS was 6.5%, with females having a significantly higher prevalence than males (6.0% vs. 7.2%, p = 0.029). In females, being overweight was independently positively associated with IBS after adjustment (adjusted odds ratio [OR]: 1.81 [95% confidence interval (CI): 1.13-2.79]). In contrast, in males, no association between being lean or overweight and IBS was found. CONCLUSIONS Among the young Japanese population, being overweight might be independently positively associated with prevalence of IBS in females but not in males.

Abstract
ObjectiveGut-directed hypnotherapy (GDH) is an evidence-based treatment for irritable bowel syndrome (IBS). Adoption of remote GDH has been accelerated by the COVID-19 pandemic. We aimed to evaluate patient experience and satisfaction following remote GDH.DesignOn completing 12 sessions of remote GDH via Skype using the Manchester protocol, patients with refractory IBS completed a feedback form on their experience. The proportion reporting positive outcomes (≥30% improvement in global IBS symptoms or abdominal pain, satisfaction, recommendation to family/friends) were compared by patient factors (age, gender, proximity, preferences).ResultsOf 52 patients completing the feedback form, 27 (52%) indicated that they would have opted for remote over face-to-face GDH, regardless of the pandemic situation. On a five-point scale (5=easy), patients rated the platform easy-to-use (mean 4.5±0.8) without impairment of communication (mean rating 4.6±0.8). Following remote GDH, 30/52 (58%) reported ≥30% global IBS symptom improvement, and 24/52 (46%) reported ≥30% pain reduction. 90% would recommend remote GDH to others. Only 39% felt they would have benefitted more from face to face. Those who would have chosen remote GDH regardless of the pandemic were more likely to be satisfied (p=0.01). Age, gender and proximity did not influence outcomes, satisfaction and likelihood of recommending remote GDH to others. Difficulties during remote sessions were infrequent in both those that were satisfied, and those that would have preferred face to face.ConclusionThese data support the need to continue developing remote GDH in the post-COVID era but suggest that there is still a role for face-to-face GDH, with patient choice being an important factor.

Abstract
Irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) are common gastrointestinal disorders imposing considerable impact on the quality of life and well-being of affected individuals. A paucity of evidence-based treatment options exist for CIC and IBS-C sufferers. Tegaserod, a 5-HT4 agonist, has a substantial body of preclinical and clinical study evidence to support its beneficial role in modulating sensorimotor function of the luminal gastrointestinal tract. Tegaserod was first approved for use by the U.S. Food and Drug Administration for the management of IBS-C and CIC in 2002 and 2004, respectively. Tegaserod enjoyed a successful uptake in the management of these disorders during its first several years of availability in the United States, but was later withdrawn from the market in 2007 over concerns related to adverse cardiovascular events. Since then, additional safety data has been generated, and following a resubmission and review by the Food and Drug Administration, in April 2019, tegaserod was once again approved for use in IBS-C under a more restricted labeling, confining use to women under 65 years of age without heart disease or additional cardiovascular risk factors. This review summarizes the regulatory journey of tegaserod and details the existing pharmacokinetic, physiologic, clinical, and safety data of tegaserod generated over the last 2 decades. The discussion also examines the future of tegaserod in the treatment of these constipation disorders, as well as its potential role in other related disorders of brain-gut interaction.

The visceral sensitivity index: A novel tool for measuring GI-symptom-specific anxiety in inflammatory bowel disease. Neurogastroenterol Motil 2022; 34:e14384.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are chronic gastrointestinal (GI) disorders. GI symptom-specific anxiety (GSA) is the cognitive, affective, and behavioral response stemming from fear of GI symptoms. The Visceral Sensitivity Index (VSI) measures GSA and is validated in IBS and may be useful in IBD. METHODS We compared VSI scores in IBD participants to IBS participants and healthy controls (HCs). Using validated questionnaires, we assessed the VSI's correlation with anxiety, health-related quality of life (HRQOL), and IBD activity. KEY RESULTS We recruited 222 age- and sex-matched participants (74 IBD [23 Crohn's disease; 51 ulcerative colitis], 74 IBS, and 74 HCs). IBD and IBS participants had higher VSI scores compared with HCs (IBD = 26.62 ± 16.64, IBS = 38.83 ± 15.06; HCs = 3.42±5.06; all p's < 0.001). VSI scores were lower in IBD vs IBS (p < 0.001). In IBD, VSI modestly correlated with current anxiety (R = 0.35, p = 0.002) and the physical component of HRQOL (R = -0.45, p = 0.0001) but less with the mental component of HRQOL (R = -0.23, p = 0.05). CONCLUSIONS & INFERENCES Our findings suggest the VSI is a useful measure in IBD. The VSI in IBD is related to general anxiety but is measuring a different construct and is not affected by the presence of trait anxiety. IBD patients have GSA that is associated with decreased HRQOL, which can negatively affect treatment compliance and other long-term disease outcomes. Future studies are needed to further validate the VSI in IBD and to assess its correlation with disease activity.

Abstract
Introduction The prevalence of irritable bowel syndrome (IBS) ranges from 7 to 18% over the world. We aimed to assess the prevalence and risk factors of irritable bowel syndrome in adults. Methodology We conducted a cross-sectional study of IBS prevalence and risk factors from March to May 2022 at KRL Hospital Islamabad. 300 people were given Pre-validated Performa's. Our research adheres to the principles outlined in the Helsinki Declaration. The PSS was used to measures how much stress a person has felt in the past month. The higher the score, the more stressed the person appears to be. A variety of mental health disorders can be evaluated using this method. Data on dietary and lifestyle factors associated with IBS for the last 12 months was also collected from the participants. Results The majority of patients, 70%, were classed as Grade 1 and 146 (48.66%) reported abdominal pain associated with defecation. 162 (54%) individuals reported high levels of tea consumed, 81 (27%) consumed coffee and 57 (19%) reported carbonated drinks consumed. 139 individuals reported having Vigorous-Intensity activity, out of which 69 (49.64%) spend 60 min of vigorous activity in a day. Conclusion Screening patients for IBS on a regular basis is critical, especially in the younger demographic. If a patient experiences any symptoms of IBS, they should contact their doctor immediately. Consider the care of patients with chronic gastrointestinal complaints, particularly in women and those at greater risk of developing the illness. Perceived Stress Scale (PSS) measures how much stress a person has felt in the past month. The Chalder Fatigue Scale (CFS) is used to measure fatigue. We recommend the younger population to be screened for IBS on a regular basis. Persistent gastrointestinal symptoms, especially women and those at high risk of the condition, it is critical to take this into account.

Abstract
BACKGROUND AND AIM Irritable bowel syndrome (IBS) is a highly prevalent disorder of gut brain interaction with a multifactorial etiology. Food trigger avoidance is common among individuals with IBS and exclusion diets are gaining popularity. However, recent guidelines on IBS management cautioned regarding the use of unsupervised dietary therapy with concerns of development of poor eating habits and even nutritional deficiencies. We aimed to review the available literature on the effect of habitual and exclusion diets on micronutrient status as well as the role of micronutrient supplementation in alleviating IBS symptoms. METHODS Four electronic databases (PubMed, Embase, Cochrane, Web of Science) were searched for articles that reported micronutrient data in patients with IBS. Serum micronutrient levels and dietary intake of micronutrients in patients with IBS were collected. The extracted data were tabulated and organized by micronutrient type to observe for trends. RESULTS Twenty-six articles were included in this systematic review (12 interventional and 14 observational studies). Studies showed that generally IBS subjects had lower levels of vitamin B2, vitamin D, calcium, and iron at baseline compared with non-IBS subjects. Studies also found that exclusion diets were associated with lower intake of micronutrients especially vitamin B1, B2, calcium, iron, and zinc. There was a lack of interventional studies on micronutrients. CONCLUSION Irritable bowel syndrome patients are at risk of developing multiple micronutrient deficiencies that may have both localized gastrointestinal as well as systemic effects. Dietary management of IBS patients should include a proper dietitian review to ensure nutritional adequacy where possible.

Abstract
BACKGROUND Irritable Bowel Syndrome (IBS) negatively influences mental and physical quality of life (QoL), but factors that explain this impact are still unclear. Increasing evidence has associated IBS severity, psychological distress, somatic symptoms, and gastrointestinal (GI)-specific anxiety with QoL in IBS. The aim of this study is to further explore these associations and to analyze potential mediating factors. METHOD A total of 1017 IBS patients (69.3% female, mean age 40.6 years) who completed a QoL measure (SF-36) were included in this study. A proportion of these participants (N = 183; 72.7% female, mean age 41.7), who additionally completed psychological distress, somatic symptoms, and GI-specific anxiety measures, was included in the mediation analysis. This analysis was conducted via structural equation modelling to identify factors of importance for generic QoL, using a cross-sectional design. RESULTS IBS patients reported lower QoL than what is observed in the general population, in particular regarding role limitations caused by health and emotional functioning, vitality, and social functioning. Female patients scored lower than male patients on most QoL dimensions. The effects of IBS severity on mental and physical QoL were mediated by GI-specific anxiety. In addition to GI-specific anxiety, depressive symptoms were also of importance for mental QoL, and somatic symptom severity for physical QoL. CONCLUSION QoL is reduced in patients with IBS and GI-specific anxiety, depressive symptoms, and somatic complaints are particularly important for this outcome. Future trials should test the efficacy of psychological interventions specifically targeting these factors in improving QoL in IBS.

Abstract
Background Fecal microbiota transplantation (FMT) is a potential treatment for irritable bowel syndrome (IBS), but its efficacy in Japanese IBS patients is unknown. This study aimed to evaluate the efficacy, side effects, and microbiome changes following FMT in Japanese IBS patients. Methods Seventeen Japanese patients with refractory IBS received FMT (4 donors) under colonoscopy. Responders were defined by an improvement in the IBS severity index (IBS-SI) of 50 points or more after 12 weeks. We evaluated the IBS-SI and Bristol Stool Form Scale (BSFS) and compared the diversity and microbiome before and 12 weeks after FMT. For the microbiome, we analyzed the V3–V4 region of the 16S rRNA gene. Results IBS-SI decreased an average of 115.58 points after 12 weeks, and 10 patients (58.8%) were considered responders. Eight patients with diarrhea (66.7%) and three patients with constipation (60.0%) showed improvement in the BSFS. Two patients complained of mild abdominal pain, but there were no cases with severe side-effects. α-diversity was increased only in the responder group (p = 0.017). Patients who closely paralleled the donor microbiome had a higher rate of IBS-SI improvement. The relative abundance of Neisseria and Akkermansia increased and Desulfovibrio and Delftia were decreased in the responder group after FMT. Conclusions Following FMT, about 60% of Japanese patients with IBS showed improvement in both the IBS-SI and BSFS, without severe side effects. Increased α-diversity and similarity to the donor microbiome after FMT may be associated with better treatment effects.

Abstract
BACKGROUND Irritable bowel syndrome patients report reduced disease-specific quality of life (IBSQOL). Factors of potential relevance for QOL include gastrointestinal (GI), psychological, and somatic symptoms, demographics, and GI motor and sensory abnormalities. OBJECTIVE The aim of our study was to evaluate the relative importance of these factors on the different IBSQOL dimensions. METHODS We included irritable bowel syndrome (IBS) patients who completed validated questionnaires to assess QOL, stool form and frequency, GI symptom severity, psychological distress, GI-specific anxiety, sense of coherence, and overall somatic symptom severity. Patients also underwent tests for oroanal transit time and rectal sensitivity. The nine dimensions of IBSQOL and their average (overall IBSQOL) were used as outcome variables, and factors associated with these were assessed using general linear models. RESULTS We included 314 IBS patients (74% female, mean age 36.3 ± 12.2 years). Higher stool frequency, GI and overall somatic symptom severity, psychological distress, and GI-specific anxiety were independently associated with reduced overall IBSQOL, with the model explaining 60% of the variance (p < 0.001). In models using each of the nine dimensions as outcomes, different association of demographic factors, GI symptoms, overall somatic symptom severity, psychological factors and sense of coherence were associated with reduced IBSQOL, explaining 20%-60% of the variance, with GI-specific anxiety being the factor that contributed most frequently. Rectal sensitivity or oroanal transit time were not independently associated with any of the dimensions. CONCLUSION Different combinations of demographic factors, GI and somatic symptoms, and psychological factors are of importance for the nine IBSQOL dimensions. Gastrointestinal-specific anxiety was the most important factor contributing to the majority of those dimensions in patients with IBS.

Abstract
BACKGROUND Bile acid diarrhoea (BAD) can be severely debilitating and negatively affect patients' quality of life (QoL). We carried out a multi-centre prospective study exploring QoL outcomes in patients with BAD after treatment with colesevelam. METHODS Patients with or without a positive 23-seleno-25-homotaurocholic acid (SeHCAT) scan were recruited and categorised into four groups: SeHCAT negative control group (CG), idiopathic BAD, post-cholecystectomy (PC) and post-terminal ileal resection for Crohn's disease (CD). Patients with a positive SeHCAT were treated with colesevelam and dosing was titrated to symptomatic response. Patients were reviewed at 4- and 8-weekly intervals and QoL was evaluated by EQ-5D-3L, SF-36, IBDQ-32 at each visit (where relevant). Patients with a negative SeHCAT (CG cohort) completed one set of questionnaires before being discharged from the study. RESULTS 47 patients (BAD = 24, PC = 12, CD = 11) completed paired QoL questionnaires before and after treatment and 30 CG patients completed a baseline questionnaire. There was a significant improvement in IBDQ-32 mean scores before and after treatment in CD patients [134.6 (95%CI 112.5-156.6) and 158.4 (136.1-180.6), respectively (p = 0.007). Following treatment, BAD patients had significantly improved mean SF-36 scores in the "Role limitation due to physical health" dimension (p = 0.02) and in the overall mental component summary (p = 0.03). Prior to starting treatment, BAD patients had the lowest scores in the 'activity' dimension of the EQ-5D-3L (p = 0.04), which improved significantly after treatment (p = 0.002). Overall, the BAD and CD cohort showed improved mean scores with treatment in all components of the SF-36 and EQ-5D-3L, while the PC cohort showed a general decline in mean scores after treatment. 55% of patients clinically responded to treatment of which 41.7%, 58.3% and 81.8% responded from the BAD, PC and CD groups respectively. Correlations between those deemed as responders with improvements on the SF-36 and EQ-5D dimensions were not statistically significant. CONCLUSION Our results demonstrate improved QoL in the BAD and CD cohort with treatment. Further larger studies are recommended specifically investigating the PC cohort and whether patients may improve with newer treatments such as FXR agonists.

Abstract
Noxious stimuli on the colorectum cause colorectal contractions through activation of descending monoaminergic pathways projecting from the supraspinal defecation center to the spinal defecation center. Since it is known that substance P is involved in the response to peripheral noxious stimuli in the spinal cord, we investigated the effects of intrathecally administered substance P at L6-S1 levels on colorectal motility in rats that were anesthetized with α-chloralose and ketamine. Intrathecally administered substance P enhanced colorectal motility, even after transection of the thoracic spinal cord at the T4 level. Severing the pelvic nerves, but not the colonic nerves, abolished substance P enhanced colorectal motility. In the spinal cord at L6-S1 levels, expression of mRNA coding neurokinin (NK) 1-3 receptors was detected by RT-PCR. Immunohistological experiments revealed that preganglionic neurons of the pelvic nerves express NK1 receptors, whereas expression of NK2 receptors was not found. In addition, substance P-containing fibers densely innervated around the preganglionic neurons expressing NK1 receptors. An intrathecally administered NK1 receptor antagonist (spantide) attenuated capsaicin-induced colorectal contractions. These results suggest that the colokinetic action of substance P is mediated by the NK1 receptor in the spinal defecation center. Our findings indicate that substance P may function as a neurotransmitter in the spinal defecation center.NEW & NOTEWORTHY We found that intrathecally administered substance P enhanced colorectal motility in anesthetized rats. Neurokinin (NK) 1 receptors, but not NK2 receptors, were detected in preganglionic neurons of the pelvic nerves. Blockade of NK1 receptors in the spinal cord attenuated the enhanced colorectal motility in response to intracolonic noxious stimuli. The findings indicate that substance P may function as a neurotransmitter in the spinal reflex pathway controlling defecation.

Abstract
BACKGROUND AND AIM Irritable bowel syndrome (IBS) is a prevalent and complex gastrointestinal disorder characterized by chronic abdominal pain and altered bowel habits. Observational studies have suggested a relationship between serum vitamin D levels and IBS symptoms. This systematic review and meta-analysis aimed to investigate the clinical effects of vitamin D supplementation on IBS symptom severity and quality of life (QoL) measures. METHODS Medline, Embase, Scopus, Web of Science, and The Cochrane Library databases were systematically searched. Data abstraction and quality assessment were conducted by four authors independently, and discrepancies were resolved through consensus from the senior author. Continuous data were pooled with standardized mean difference (SMD) using the DerSimonian and Laird's random-effects model. Sensitivity analysis by risk of bias and potentially "predatory" publication were performed as well. RESULTS A total of 685 patients across eight studies were included in the meta-analysis. Vitamin D supplementation significantly improved IBS symptom severity scale scores, with a SMD of -0.77 (95% confidence interval [CI] -1.47 to -0.07, P = 0.04, I2 = 91%). Improvements in IBS-QoL scores were also observed, albeit not statistically significant (SMD 0.54; 95% CI -0.34 to 1.41, P = 0.15, I2 = 87%). However, small sample sizes, a relatively young study population, limited ethnicities, and varied vitamin D dosing strategies across the studies were notable limitations. CONCLUSIONS Vitamin D supplementation could be part of our clinical armamentarium when managing IBS patients due to the potential efficacy and good safety profile. Further randomized, controlled trials are required to confirm the therapeutic effects.
