RESUMEN
Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder, characterized by changes of the intestinal habit associated with abdominal pain. This study analyzed factors associated with this pathology during the COVID-19 pandemic, and it was seen that the impact of IBS was higher in young women who had ongoing studies in the medical field. OBJECTIVES: Determine the prevalence of IBS in medical students and explore the associated factors with the increase of its symptoms, through the use of digital tools. MATERIALS AND METHODS: Descriptive observational study with exploration of associations, with non-probabilistic sampling, until reaching the minimum sample of 110 participants with a confidence interval of 95%, finally having a total sample of 131 students, distributed in 3 proportional and representative subgroups of the last 3 years of study of the medical career from a university from Lima, Peru. The inclusion criteria were students of both sexes and legal age, who gave their consent to participate and did not have risk factors for GI disease. Once the study was approved, the link of a validated virtual questionnaire was shared through the institutional email. To explore the associated factors, the Chi-square test was used with a statistical significance of p < 0.05. RESULTS: Responses were obtained from 195 students; 64 (32.82%) of them had at least one exclusion criteria, finally having a sample size of 131; 64 (48.85%) were women, and 52 (39.69%) were from 7th year. Using the Rome IV criteria, 23 participants were classified as having IBS, which indicates a prevalence of 17.56%, 14 (60.87%) of them were women and 10 (43.48%) were from the 7th year (last year of study of the medical career in Peru). It was observed that 1 in 3 students (32.06%) had chronic abdominal pain, and 1 in 2 (53.44%) reported having a history of Major Depression or Generalized Anxiety Disorder. Of the total, 51 (38.93%) had a history of having a positive COVID-19 test result. Regarding the associated factors, a significant association was only found between IBS and the diarrhea type, classified according to the Bristol Scale. CONCLUSIONS: The prevalence of IBS in medical students was 17.56%, the highest compared with studies in the general population and in medical students using Rome IV criteria. Of the associated factors, the clinical presentation of diarrhea, according to the Bristol scale, was associated with IBS.

Objective: To identify possible tests along with their accuracies that may be used to diagnose irritable bowel syndrome. METHODS: The systematic review comprised literature search on Cochrane Library, PubMed, Science Direct and Elsevier databases for randomised controlled trials and cohort studies conducted from January 1, 2015, to December 31, 2022, using appropriate key words and Boolean operators. Focus was kept on studies that reported irritable bowel syndrome diagnosis as the primary outcome. The risk of bias was assessed using quality assessment, data abstraction, and synthesis version 2. RESULTS: Of the 2,798 studies initially identified, 10(0.35%) were analysed in detail. Of them, 4(40%) used enzyme-linked immunosorbent assay kits to test for anti-cytolethal distending toxin B and anti-vinculin levels, 2(20%) used the kits for serum cytokine profiling and serum calprotectin levels, and 4(40%) used either magnetic resonance imaging scans, faecal metabolic profiling, intestinal biopsy analysis with immunostaining or polymerase chain reaction for differential transferribonucleic acid-derived small ribonucleic acid. Out of the 4(40%) studies on anti-cytolethal distending toxin B and anti-vinculin levels, optical densities >1.56 and >1.60 recorded 100% specificity for irritable bowel syndrome with diarrhoea, but sensitivity was 22%. In contrast, rectal biopsies for cell densities of somatostatin and peptide YY showed high sensitivity and specificity for irritable bowel syndrome ranging 80-90%. Conclusion: Enzyme-linked immunosorbent assay testing for anti-cytolethal distending toxin B and anti-vinculin as well as rectal biopsies for cell densities could be potential diagnostic tests for irritable bowel syndrome.

In this article we present a protocol for the use of the low-FODMAP diet in paediatric patients and review of the current evidence on its efficacy. These short-chain carbohydrates, which can be fermented by the intestinal microbiota, are found in a wide variety of foods, mainly of plant origin. The low-FODMAP diet is a therapeutic tool used for the management of gastrointestinal disorders such as irritable bowel syndrome. The sources we used were PubMed, Web of Science, Google Scholar and institutional websites. Following consumption of FODMAP-rich foods, a series of end products are generated that are not absorbed, giving rise to symptoms. Before starting a low-FODMAP diet, it is important to carry out a diagnostic evaluation including any applicable tests. Treatment is structured in 3 phases: elimination, reintroduction and personalization phase. In the first phase, FODMAP-rich foods are eliminated for 2-3 weeks. In the second phase, lasting 8 weeks, FODMAP-rich foods are gradually reintroduced. The last phase consists in customizing the diet according to individual tolerance. This article details which foods contain FODMAPs and possible substitutes. In addition, specific food diary/intake tracking and educational materials are provided in a series of appendices to facilitate adherence to the diet. Although most studies have been conducted in adults, there is also some evidence on the beneficial effects in the paediatric age group, with a reduction of symptoms, especially in patients with functional gastrointestinal disorders. Nevertheless, more research is required on the subject.

ABSTRACT: Irritable bowel syndrome (IBS) is a common and burdensome disorder characterized by chronic recurrent abdominal pain and altered bowel habits. IBS remains misunderstood, leading to delayed diagnosis, impaired quality of life, and substantial healthcare costs. Advancing clinicians' understanding of this complex biopsychosocial process, using a positive diagnostic strategy rather than a diagnosis of exclusion, and incorporating a multimodal treatment approach expedite time to diagnosis, facilitate symptom relief, and reduce financial expenditure.

Gastroenteritis is inflammation of the stomach and intestines; colitis is inflammation of the colon. Viruses are the most common cause, followed by bacteria and parasites. Incidence of the various infections varies by age, sex, location, and vaccine availability; vaccination has reduced rotavirus infections by as much as 90% in children. Postinfectious complications include irritable bowel syndrome (IBS) and lactose intolerance. Approximately 9% of patients with acute gastroenteritis or colitis develop postinfectious IBS, which accounts for more than 50% of all IBS cases. The diagnostic approach to gastroenteritis and colitis varies with symptom severity. Microbial studies are not needed with mild symptoms that resolve within a week, but longer-lasting or more severe symptoms (including bloody stool) warrant microbial studies. In addition, recent antibiotic exposure should prompt testing for Clostridioides difficile. Multiplex antimicrobial testing is preferred; stool cultures and microscopic stool examinations are no longer first-line tests. Management depends on severity. Patients with mild or moderate symptoms are treated with oral hydration if tolerated; nasogastric or intravenous hydration are used for those with more severe illness. In addition, antiemetic, antimotility, and/or antisecretory drugs can be used for symptom control. Antimicrobial therapy is indicated for C difficile infections, travel-related diarrhea, other bacterial infections with severe symptoms, and parasitic infections.

BACKGROUND: With an increasing number of patients with irritable bowel syndrome (IBS) and availability of many pharmacological treatment options, there is an urgent need to develop and validate IBS biomarkers for prognostication and selection of patients for treatment and monitoring. The usage of investigations is limited because of its invasive nature, poor patient acceptability, and sampling variability. The bibliometric analysis of biomarker discovery of IBS articles will help in understanding current research trends of biomarkers study of IBS. AIM: To study the most highly cited articles from literature search on the biomarker for IBS to provide simple educational source. STUDY DESIGN: A bibliometric literature review-the electronic search by terms and keywords were searched in PubMed databases. The commonly cited article was searched from 1985 to 2023. The total citation number was received from knowledge search engines like Google Scholar. Articles were classified according to number of citations, year of publication, journal name, authors, publications from continents of countries of origin, research hotspots, and article title. The articles written in English and other languages were included in the analysis. RESULTS: Total number of articles found was 1,449. The mean number of citations per article was 177. The citation count ranged from 24 to 1,191. The articles with citations >30 were included in the study. The majority of articles (n = 175) were published between 2016 and 2023. Among the highly cited articles, the most prevalent topic of interest was biomarker discovery. Most of the articles were original articles. The continent of origin for most of the articles was the United States of America (n = 163), Europe (n = 145), United Kingdom (n = 23), Asia (n = 23), Australia (n = 14), etc. Conclusion: The analysis of articles on biomarker discovery for IBS will help in understanding the requirement for unmet need for the discovery of biomarker for IBS. The current bibliometric study has highlighted the work of authors with advanced knowledge about discovery of the biomarker for IBS. This study will help to identify the current trends in the biomarker discovery for IBS and help for the further evolution of the field.

INTRODUCTION: High FODMAP (fermentable oligo-, di, monosaccharides and polyols) foods have been linked with worsening symptoms of IBS patients. The aim was to compare gastrointestinal symptoms and dietary intake of patients with irritable bowel syndrome following a low FODMAP diet, with or without individual nutrition therapy. MATERIALS AND METHODS: A total of 54 patients that met Rome IV criteria for IBS were randomized into two groups, guided group (individual nutrition therapy, n=28) and self-management group (learned about low FODMAP diet online, n=26). Both groups followed low FODMAP diet for 4 weeks. Four-day food records were used to assess dietary intake. Symptoms were assessed by the IBS-severity scoring system (ISB-SSS). RESULTS: The number of subjects who did not complete the study was 13, thereof five in the nutrition therapy and eight in the self-management group, leaving 23 and 18 subjects available for analysis, respectively. Symptoms declined from baseline to endpoint in both groups, by 183±101 points on average in the group receiving nutrition therapy (p< 0.001) and 132±110 points in the self-management group (p< 0.001), with no difference between groups. At baseline, about 80% of meals in both groups contained food high in FODMAP's. The corresponding proportion was 9% and 36% in week 3 in the nutrition therapy and self-management group, respectively (p< 0.001). CONCLUSION: Both groups experienced relieve of symptoms, but compliance to the low FODMAP diet was better in the group receiving individual nutrition therapy compared with the group who only received instructions on how to learn about low FODMAP diet online.

INTRODUCTION: Long-term studies characterizing the natural history of functional bowel disorder (FBD) from community-based settings and exploring association with psychological factors are sparse. We aimed to evaluate the evolution of symptoms, health outcomes, and association of FBD with psychological disorders in Chinese population. METHODS: Individuals identified from random sampling of residents of Hangzhou, China, participated in a baseline survey in January 2010. Follow-up phone survey was conducted in December 2018. FBD was diagnosed based on Rome III criteria. RESULTS: Among 452 individuals (mean age 44.6 ± 15.3 years, 174 [38%] male) who completed the study, the prevalence of FBD was 36.3% (95% confidence interval [CI] 32.6-40.0%) at enrollment and 36.1% (95% CI 32.3-39.8%) at follow-up survey ( P = 0.94). However, 214 individuals (47%) had interval change in diagnosis. Although no difference in incidence of organic disease or death was observed, a higher proportion of patients with FBD (16/164, 9.8% vs 9/288, 3.1%; P = 0.003) compared with those without FBD received non-cancer-related abdominal and/or pelvic surgery during follow-up. FBD was associated with anxiety and/or depression at initial (adjusted odds ratio [AOR] = 1.7, 95% CI 1.7-2.7, P = 0.02) and follow-up (AOR = 8.0, 95% CI 3.2-20.0, P < 0.001) surveys. Diagnosis of FBD at baseline was associated with new-onset anxiety and/or depression at follow-up (AOR = 3.2, 95% CI 1.2-8.3, P = 0.01). DISCUSSION: Although the prevalence of FBD remained stable, transformation of symptoms was common over time. Patients with FBD may have increased risk of receiving non-cancer-related abdominal and/or pelvic surgery. FBD symptoms at baseline increased the risk of new-onset anxiety and/or depression by 3.2-fold over the next 9 years.

BACKGROUND: There is compelling evidence that microbe-host interactions in the intestinal tract underlie many human disorders, including disorders of gut-brain interactions (previously termed functional bowel disorders), such as irritable bowel syndrome (IBS). Small intestinal bacterial overgrowth (SIBO) has been recognized for over a century in patients with predisposing conditions causing intestinal stasis, such as surgical alteration of the small bowel or chronic diseases, including scleroderma and is associated with diarrhea and signs of malabsorption. Over 20 years ago, it was hypothesized that increased numbers of small intestine bacteria might also account for symptoms in the absence of malabsorption in IBS and related disorders. This SIBO-IBS hypothesis stimulated significant research and helped focus the profession's attention on the importance of microbe-host interactions as a potential pathophysiological mechanism in IBS. PURPOSE: However, after two decades, this hypothesis remains unproven. Moreover, it has led to serious unintended consequences, namely the widespread use of unreliable and unvalidated breath tests as a diagnostic test for SIBO and a resultant injudicious use of antibiotics. In this review, we examine why the SIBO hypothesis remains unproven and, given the unintended consequences, discuss why it is time to reject this hypothesis and its reliance on breath testing. We also examine recent IBS studies of bacterial communities in the GI tract, their composition and functions, and their interactions with the host. While these studies provide important insights to guide future research, they highlight the need for further mechanistic studies of microbe-host interactions in IBS patients before we can understand their possible role in diagnosis and treatment of patient with IBS and related disorders.

OBJECTIVE: To investigate factors related to the risk of developing irritable bowel syndrome (IBS) or Helicobacter pylori infection. METHODS: This cross-sectional, questionnaire-based study analysed the responses from participants that completed an online questionnaire, which asked about their knowledge of the causes and risk factors associated with IBS and H. pylori infection. RESULTS: The study analysed responses from 230 participants: 181 females (of 227 participants; 79.7%) and 190 aged 18-40 years (of 228; 83.3%). Of the 230 participants, 40 (17.4%) had been diagnosed by a physician with IBS and 57 (24.8%) had been diagnosed with H. pylori infection. Of 226 participants, 93 (41.2%) had self-medicated with antibiotics in the past 6 months for various reasons. The overall mean ± SD knowledge score about IBS and H. pylori infection for the study cohort (n = 230) was 35.8 ± 19.2%. Wald χ2-test analysis demonstrated that chronic diseases, antibiotic use and having an endoscopy were significantly associated with developing IBS. Male sex and chronic diseases were significantly associated with H. pylori infection. Logistic regression analysis showed no relationship between IBS and H. Pylori infection. CONCLUSION: Chronic diseases was the only risk factor common for IBS and H. pylori infection.

Background: Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder (FGID) with heterogeneous clinical presentations. There are no clear testing parameters for its diagnosis, and the complex pathophysiology of IBS and the limited time that doctors have to spend with patients makes it difficult to adequately educate patients in the outpatient setting. An increased awareness of IBS means that patients are more likely to self-diagnose and self-manage IBS based on their own symptoms. These factors may make patients more likely to turn to Internet resources. Wikipedia is the most popular online encyclopedia among English-speaking users, with numerous validations. However, in Mandarin-speaking regions, the Baidu Encyclopedia is most commonly used. There have been no studies on the reliability, readability, and objectivity of IBS information on the two sites. This is an urgent issue as these platforms are accessed by approximately 1.45 billion people. Objective: We compared the IBS content on Wikipedia (in English) and Baidu Baike (in Chinese), two online encyclopedias, in terms of reliability, readability, and objectivity. Methods: The Baidu Encyclopedia (in Chinese) and Wikipedia (in English) were evaluated based on the Rome IV IBS definitions and diagnoses. All possible synonyms and derivatives for IBS and IBS-related FGIDs were screened and identified. Two gastroenterology experts evaluated the scores of articles for both sites using the DISCERN instrument, the Journal of the American Medical Association scoring system (JAMA), and the Global Quality Score (GQS). Results: Wikipedia scored higher overall with DISCERN (p < .0001), JAMA (p < .0001) and GQS (p < .05) than the Baidu Encyclopedia. Specifically, Wikipedia scored higher in DISCERN Section 1 (p < .0001), DISCERN Section 2 (p < .01), DISCERN Section 3 (p < .001), and the General DISCERN score (p < .0001) than the Baidu Encyclopedia. Both sites had low DISCERN Section 2 scores (p = .18). Wikipedia also had a larger percentage of high quality scores in total DISCERN, DISCERN Section 1, and DISCERN Section 3 (p < .0001, P < .0001, P < .0004, respectively, based on the above 3 (60%) rule). Conclusions: Wikipedia provides more reliable, higher quality, and more objective IBS-related health information than the Baidu Encyclopedia. However, there should be improvements in the information quality for both sites. Medical professionals and institutions should collaborate with these online platforms to offer better health information for IBS.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal (GI) disorder characterized by altered bowel habits and abdominal discomfort during defecation. It significantly impacts life quality and work productivity for those affected. Global data suggests a slightly higher prevalence in females than in males. Today, unambiguous diagnosis of IBS remains challenging due to the absence of a specific biochemical, histopathological, or radiological test. Current diagnosis relies heavily on thorough symptom evaluation. Efforts by the Rome committees have established standardized diagnostic criteria (Rome I-IV), improving consistency and clinical applicability. Recent studies in this framework, seem to have successfully employed metabolomics techniques to identify distinct metabolite profiles in breath and stool samples of IBS patients, differentiating them from healthy controls and those with other functional GI disorders, such as inflammatory bowel disease (IBD). Building on this success, researchers are investigating the presence of similar metabolites in easily accessible biofluids such as urine, potentially offering a less invasive diagnostic approach. Accordingly, this review focuses on key metabolites specifically detected in IBS patients' biological specimens, with a focus on urinary metabolites, using various methods, particularly mass spectrometry (MS)-based techniques, including gas chromatography-MS (GC-MS), liquid chromatography-tandem MS (LC-MS/MS), and capillary electrophoresis-MS (CE-MS) metabolomics assays. These findings may make provision for a new set of non-invasive biomarkers for IBS diagnosis and management.

OBJECTIVES: Fibromyalgia, chronic fatigue syndrome, and irritable bowel syndrome are highly prevalent conditions and part of the functional somatic syndromes (FSS) diagnosis, that are classified under the unifying umbrella term functional somatic disorder (FSD). Multiple factors are associated with FSD symptom development; However, few studies have explored these associations in relation to the diagnosis status. This study aims to examine associations with a previously received FSS diagnosis from a physician in participants fulfilling the FSD diagnostic criteria in a population-based sample. METHODS: This research employs a comprehensive observational approach using a cross sectional design with data from the DanFunD part two cohort. Information about received FSS diagnoses was obtained from self-reported questionnaires. Participants fulfilling the FSD diagnostic criteria were identified with both self-reported questionnaires and diagnostic interviews. Validated questionnaires were used to assess the examined factors. RESULTS: 1704 cases fulfilled the diagnostic criteria for an FSD according to questionnaires or interviews in the DanFunD study. In participants fulfilling the diagnostic criteria, having previously received an FSS diagnosis by a physician was strongly associated with female sex, negative illness perceptions and poor health-related quality of life for questionnaire and interview-based diagnoses. Less consistent associations were observed for lower socioeconomic status, anxiety, and adverse life events. CONCLUSION: Previously received FSS diagnoses showed associations with multiple factors with a particular strong association with female sex and poor health related quality of life.

Background: The early establishment of prophylaxis and immediate administration of anticoagulant therapy upon the diagnosis of venous thromboembolism should be the treatment objectives in these patients. Objective: The study aimed to determine the optimal cut-off point of Calprotectin, IL-6 (interleukin-6), CRP (C reactive protein) to differentiate UC, IBS-D. Methods: A cross-sectional descriptive study of 335 individuals ≥15 years old was performed, including 31 healthy controls, 215 with IBS-D, 71 diagnosed with UC, and 18 diagnosed with CD. Receiver Operating Characteristics (ROC), sensitivity, specificity, and area under curve (AUC) were computed. Results: The results showed that the median value of calprotectin (IQR) in healthy participants was 20.0 (6.0 - 34.0) µg/g; 17,7 (8,7-38,9) µg/g in IBS-D group; 1710.0 (588 - 4260,0) µg/g in UC group; and 560.5 (177.8 - 1210.0) µg/g in CD group. Calprotectin concentration in IBD group including UC and CD was higher than IBS-D with p<0.05. The median value of CRP (range IQR) was 1,3 (0,9 - 2,3) mg/L in IBS-D group; 7.0 (2.4 -16.6) mg/L in UC group; and 10.1 (2.2 - 42.5) mg/L in CD group. CRP concentration in IBD group including UC and CD was higher than IBS-D with p<0.05. The median value of IL-6 (range IQR) was 2.3 (1.6 - 5.7) pg/mL in IBS-D group; 16.8 (9.4 - 47.0) pg/mL in UC group; and 9.4 (7.9 - 11.0) pg/mL in CD group. Calprotectin concentration in IBD group including UC and CD was higher than IBS-D with p<0.05. The optimal cut-off point of calprotectin that differentiated IBS-D from IBD was 110.5 µg/g, with sensitivity and specificity of 93.3% and 91.4%, respectively; of IL-6 was 7.2 pg/mL with sensitivity and specificity of 92.0% and 78.0%, respectively; of CRP of 2.4 mg/L had specific sensitivities of 83.3% and 86.0%, respectively. Conclusion: The Calprotectin immunoassay has the best value in discriminating between IBD and IBS-D.

Irritable bowel syndrome (IBS) is a condition that affects approximately one in 10 people in the United States (Defrees & Bailey, 2017). Despite the high prevalence of IBS, the medical community struggles to effectively understand, diagnose, and treat this disorder (Ankersen et al., 2021). In recent years, an increasing number of health-tech companies have emerged to offer integrated treatment of IBS via telemedicine. This pilot study explores the patient experience of virtual, multidisciplinary IBS care through a U.S.-based company, Oshi Health. Semistructured interviews were conducted followed by thematic analysis to identify commonalities between patient experience and perspective (Van Manen, 2014). Overarching themes were identified as follows: loss of the grocer, a broken system, and the power of self-trust. Although several limitations exist, including small sample size, the study offers insight into the experience of telemedicine services for IBS and provides a framework for future research.

BACKGROUND: Various dietary strategies for managing irritable bowel syndrome (IBS) target mechanisms such as brain-gut interactions, osmotic actions, microbial gas production, and local immune activity. These pathophysiological mechanisms are diverse, making it unclear which foods trigger IBS symptoms for a substantial proportion of patients. AIM: To identify associations between foods and gastrointestinal symptoms. METHODS: From the mySymptoms smartphone app, we collected anonymized diaries of food intake and symptoms (abdominal pain, diarrhea, bloating, and gas). We selected diaries that were at least 3 weeks long. The diaries were analyzed for food-symptom associations using a proprietary algorithm. As the participants were anonymous, we conducted an app-wide user survey to identify IBS diagnoses according to Rome IV criteria. RESULTS: A total of 9,710 food symptom diaries that met the quality criteria were collected. Of the survey respondents, 70% had IBS according to Rome IV criteria. Generally, strong associations existed for caffeinated coffee (diarrhea, 1-2 h postprandial), alcoholic beverages (multiple symptoms, 4-72 h postprandial), and artificial sweeteners (multiple symptoms, 24-72 h postprandial). Histamine-rich food intake was associated with abdominal pain and diarrhea. Some associations are in line with existing literature, whilst the absence of an enriched FODMAP-symptom association contrasts with current knowledge. CONCLUSIONS: Coffee, alcohol, and artificial sweeteners were associated with GI symptoms in this large IBS-predominant sample. Symptom onset is often within 2 h postprandial, but some foods were associated with a delayed response, possibly an important consideration in implementing dietary recommendations. Clinical trials must test the causality of the demonstrated food-symptom associations.

BACKGROUND: Persistent gastrointestinal symptoms are prevalent in adult patients with inflammatory bowel disease (IBD), even when endoscopic remission is reached. These symptoms can have profound negative effects on the quality of life of affected patients and can be difficult to treat. They may be caused by IBD-related complications or comorbid disorders, but they can also be explained by irritable bowel syndrome (IBS)-like symptoms. AIMS: To provide a practical step-by-step guide to diagnose and treat persistent gastrointestinal symptoms in patients with IBD in remission via a personalised approach. METHODS: We scrutinised relevant literature on causes, diagnostics and treatment of persistent gastrointestinal symptoms (abdominal pain or discomfort, bloating, abdominal distension, diarrhoea, constipation and faecal incontinence) in patients with IBD in remission. RESULTS: A graphical practical guide for several steps in diagnosing, identifying potential triggers and adequate treatment of persistent gastrointestinal symptoms in IBD in remission is provided based on supporting literature. The first part of this review focuses on the diagnostic and treatment approaches for potential IBD-related complications and comorbidities. The second part describes the approach to IBS-like symptoms in IBD in remission. CONCLUSIONS: Persistent gastrointestinal symptoms in IBD in remission can be traced back to potential pathophysiological mechanisms in individual patients and can be treated adequately. For both IBD-related complications and comorbidities and IBS-like symptoms in IBD in remission, pharmacological, dietary, lifestyle or psychological treatments can be effective. A systematic and personalised approach is required to reduce the burden for patients, healthcare systems, and society.
