The purpose of this study is to determine the frequency of irritable bowel syndrome (IBS) and the influencing factors in children aged 4 to 9. The cross-sectional descriptive study included 1176 children between the ages of 4 and 9 who applied for Family Medicine Centers between March 1, 2017 and April 30, 2017 for various reasons. Pediatric Gastrointestinal Symptoms Questionnaire, Roma III Version (QPGS-RIII) was applied to the volunteers (children's parents or caregivers), and Beck Anxiety Scale was applied to the mothers accompanying their children. A total of 603 (51.9%) of the children included in the study were female and 559 (48.1%) were male. When the applied QPGS-RIII was evaluated with IBS diagnostic criteria, IBS was found in 137 children and IBS frequency was found to be 11.8% (95% confidence interval [CI]). Significant differences were found in socioeconomic level, eating habits, TV-watching habits, and IBS status (P <.05). [ABSTRACT FROM AUTHOR]

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.

The irritable bowel syndrome (IBS) is a functional gastrointestinal disorder (FGID), whose prevalence has widely increased in pediatric population during the past two decades. The exact pathophysiological mechanism underlying IBS is still uncertain, thus resulting in challenging diagnosis and management. Experts from 4 Italian Societies participated in a Delphi consensus, searching medical literature and voting process on 22 statements on both diagnosis and management of IBS in children. Recommendations and levels of evidence were evaluated according to the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus was reached for all statements. These guidelines suggest a positive diagnostic strategy within a symptom-based approach, comprehensive of psychological comorbidities assessment, alarm signs and symptoms' exclusion, testing for celiac disease and, under specific circumstances, fecal calprotectin and C-reactive protein. Consensus also suggests to rule out constipation in case of therapeutic failure. Conversely, routine stool testing for enteric pathogens, testing for food allergy/intolerance or small intestinal bacterial overgrowth are not recommended. Colonoscopy is recommended only in patients with alarm features. Regarding treatment, the consensus strongly suggests a dietary approach, psychologically directed therapies and, in specific conditions, gut-brain neuromodulators, under specialist supervision. Conditional recommendation was provided for both probiotics and specific fibers supplementation. Polyethylene glycol achieved consensus recommendation for specific subtypes of IBS. Secretagogues and 5-HT4 agonists are not recommended in children with IBS-C. Certain complementary alternative therapies, antispasmodics and, in specific IBS subtypes, loperamide and rifaximin could be considered. [ABSTRACT FROM AUTHOR]

Microscopic colitis, a diagnosis under the umbrella term of inflammatory bowel disease, is a prevalent cause of watery diarrhea, often with symptoms of urgency and bloating, typically observed in older adults aged ≥ 60 years. Its incidence has been reported to exceed those of ulcerative colitis and Crohn's disease in some geographical areas. Although nonpathognomonic endoscopic abnormalities, including changes of the vascular mucosal pattern; mucosal erythema; edema; nodularity; or mucosal defects, e.g., "cat scratches" have been reported, a colonoscopy is typically macroscopically normal. As reliable biomarkers are unavailable, colonoscopy using random biopsies from various parts of the colon is compulsory. Based on the histological examination under a microscope, the disease is divided into collagenous (with a thickened subepithelial collagenous band) and lymphocytic (with intraepithelial lymphocytosis) colitis, although incomplete forms exist. In routine clinical settings, the disease has a high risk of being misdiagnosed as irritable bowel syndrome or even overlooked. Therefore, healthcare providers should be familiar with clinical features and rational management strategies. A 6–8-week oral budesonide treatment course (9 mg/day) is considered the first-line therapy, but patients often experience relapse when discontinued, or might become intolerant, dependent, or even fail to respond. Consequently, other therapeutic options (e.g., bismuth subsalicylate, biologics, loperamide, bile acid sequestrants, and thiopurines) recommended by available guidelines may be prescribed. Herein, clinically meaningful data is provided based on the latest evidence that may aid in reaching a diagnosis and establishing rational therapy in geriatric care to control symptoms and enhance the quality of life for those affected.

Background & Aim: Irritable bowel syndrome (IBS) is a functional disorder of the gastrointestinal tract that affects 5-30% of the world's population and is characterized by abdominal pain and changes in bowel habits. It has been shown that mood; anxiety and physical disorders are associated with different degrees of psychological distress in patients with IBS. The purpose of the present study is to compare the frequency of psychiatric symptoms of irritable bowel syndrome patients one year after diagnosis with the control group using self-assessment method. Materials & methods: In this descriptive-cross-sectional study, the number of 48 patients with irritable bowel syndrome (according to the Rome IV criteria) and 48 non-sufferers among those who referred to the gastroenterology clinic of Shahid Sayad Shirazi Hospital in Gorgan, with the available sampling method Selection and study were entered. Informed consent was obtained from the participants. Data were collected using checklist and SCL-90-R questionnaire. Then, using SPSS version 16 software and chi-square and Mann-Whitney tests, they were analyzed statistically. Results: The two groups of case and control were similar in terms of demographic variables, including age, gender, education, marital status, and place of residence (p<0.05). There was no difference between the two groups in terms of the total score and the score of the subscales of SCL-90-R (p<0.05). None of the demographic variables and psychiatric symptoms were identified as risk factors for IBS (p<0.05). Conclusion: Based on the results of this study, patients with irritable bowel syndrome are similar to non-affected people in terms of psychiatric symptoms. Also, demographic variables and psychiatric symptoms are risk factors for they did not suffer from irritable bowel syndrome. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) and endometriosis pose significant challenges to affected individuals. IBS, which is a functional gastrointestinal disorder, affects 5-10% of the population, while endometriosis affects 1 in 10 of those assigned female at birth. Despite distinct origins, symptom often overlap, which may lead to misdiagnosis. Diagnosing IBS and endometriosis requires a comprehensive approach. Nutritional management for IBS emphasises self-help strategies, nutritional changes and gut--brain axis modulation. The low FODMAP diet, which reduces the intake of foods containing specific types of carbohydrate, can be effective but requires the support of trained health professionals. For the management of endometriosis, a Mediterranean-style diet rich in antioxidants shows promise. Gastrointestinal symptoms are common with endometriosis and an individualised approach is recommended. Furthermore, vitamin D status assessment is advised. Collaboration between health professionals and dietitians is vital for tailored interventions, to enhance the wellbeing of individuals with IBS or endometriosis. A holistic approach holds promise in symptom management for both conditions. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome is a significant health problem that can affect up to 11% of the general population. The problem is far more common among women and young people, especially in their thirties. The aetiology of the disease is not fully understood, but it is now thought that dysregulation of the gut-brain axis may be one of the causes. In addition, psychogenic factors, genetics and dietary habits have been attributed a role in the development of the disease. The diagnosis of the disease is based on the clinical picture and the exclusion of other organic causes that may lead to clinical symptoms. According to the Rome IV criteria, diagnosis of IBS is possible when recurrent abdominal pain is found, occurring at least once a week, for the last 3 months. The pain must be accompanied by at least 2 of the following criteria: it is associated with a bowel movement, with a change in the frequency of bowel movements or with a change in the consistency of the stool. Irritable bowel syndrome is a chronic, recurrent condition, with varying frequency of exacerbations and quiescence, dependent on a number of factors. As no clear aetiology has been established to date, we therefore have no causal treatment and no effective and lasting cure. In this situation, treatment must be comprehensive, involving non-pharmacological management related to changes in lifestyle and eating habits and, in the absence of adequate therapeutic effects, pharmacological treatment. Pharmacological treatment should be symptomatic, targeting the predominant complaints and types of IBS, and we can reach for muscle relaxants, drugs to stimulate intestinal peristalsis, antidepressants, rifaximin, laxatives, antidiarrheals and drugs for bloating, probiotics and herbal medicines, e.g. peppermint oil.

Objective: To examine disparities between primary care provider (PCP) and gastroenterologist diagnosis and management of irritable bowel syndrome (IBS). Design: Retrospective cross-sectional study. Setting: A 547-bed quaternary-care hospital within the Loyola University Healthcare System. Participants: 1000 patients aged 18-65 with an ICD-10 diagnosis of IBS Methods: We randomly selected 1000 patients aged 18 to 65 years within the Loyola University Healthcare System's electronic medical record with an ICD-10 diagnosis of IBS. Physician notes and diagnostic results were reviewed for documentation of symptoms fulfilling Rome IV criteria and resolution of symptoms. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of primary diagnoses assigned by PCPs and gastroenterologists were assessed along with number of diagnostic tests ordered. Results: The mean age (SD) was 45 (12) years, and 76.9% were female. Sensitivity of an IBS diagnosis by a PCP was 77.6% (95% CI 73.3-81.9), compared with 60.1% (95% CI 54.7-65.6) for a gastroenterologist. Specificity of an IBS diagnosis by a PCP was 27.5% (95% CI 23.5-31.5), compared with 71.1% (95% CI 64.6-77.5) for a gastroenterologist diagnosis of IBS. A gastroenterologist diagnosis of IBS carried a high PPV (77.3%, 95% CI 72.0-82.6) compared with 44.6% (95% CI 40.7-48.5) for a PCP. Of 180 patients with outcome data, 69.4% had resolution of symptoms at follow-up. Conclusion: The sensitivity of gastroenterologist diagnosis of IBS closely matches the sensitivity of Rome IV criteria in validation studies. The high specificity and PPV of gastroenterologists suggest more cautious diagnosis by gastroenterologists, with PCPs more likely to assign a diagnosis of IBS incorrectly or without sufficient documentation of symptoms fulfilling Rome IV criteria. Reported resolution rates suggest primary care management of IBS is appropriate, but PCPs may benefit from gastroenterologist consultation and diagnostic guidelines for greater specificity in diagnosing IBS.

Temporal trajectories of health, illness and disability—from biographical change to micro‐embodied practices within social time—are important strands within medical sociology and disability studies. Drawing upon a UK‐based qualitative study using diaries and follow‐up interviews to explore everyday life with irritable bowel syndrome (IBS), this article explores routines when living with the condition. It focuses specifically on accounts of routines being anticipated, slowed down and stretched out to accommodate and/or care for bodies, with personal and social rhythms weaved in, out and with each other. Such reflections are told through participants' accounts of knowing routines and rhythms, stretching out and pacing morning routines to care for the body and how everyday practices are reimagined as the body and the social meet. Drawing upon the concept of 'Crip Time' where the social bends to meet with the body, this article seeks to illuminate important intersections between medical sociology and disability studies through accounts of living with IBS. This article demonstrates the entanglement of structural, disabling temporal rhythms and embodied temporalities, through an acknowledgement of routines reimagined. It offers a contribution to both medical sociology and disability studies in reimagining social lives with embodied temporalities in mind. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) is a disorder of a gut-brain interaction characterised by abdominal pain and a change in stool form or frequency. Current symptom-based definitions and the classification of IBS promote heterogeneity amongst patients, meaning that there may be several different pathophysiological abnormalities leading to similar symptoms. Although our understanding of IBS is incomplete, there are several indicators that the microbiome may be involved in a subset of patients. Techniques including a faecal sample analysis, colonic biopsies, duodenal aspirates or surrogate markers, such as breath testing, have been used to examine the gut microbiota in individuals with IBS. Because of a lack of a clear definition of what constitutes a healthy gut microbiota, and the fact that alterations in gut microbiota have only been shown to be associated with IBS, a causal relationship is yet to be established. We discuss several hypotheses as to how dysbiosis may be responsible for IBS symptoms, as well as potential treatment strategies. We review the current evidence for the use of antibiotics and probiotics to alter the microbiome in an attempt to improve IBS symptoms. Rifaximin, a non-absorbable antibiotic, is the most studied antibiotic and has now been licensed for use in IBS with diarrhoea in the USA, but the drug remains unavailable in many countries for this indication. Current evidence also suggests that certain probiotics, including Lactobacillus plantarum DSM 9843 and Bifidobacterium bifidum MIMBb75, may be efficacious in some patients with IBS. Finally, we describe the future challenges facing us in our attempt to modulate the microbiome to treat IBS. [ABSTRACT FROM AUTHOR]

Aim: This study aimed at assessing the efficacy of targeted interventions addressing common food sensitivities and lifestyle factors that commonly contribute to the presentation of gastrointestinal problems identified as Irritable bowel syndrome (IBS). Background: IBS has served to cover the expression of multifactorial disorders with variable aetiology and pathophysiology. Food antigens implicated in the modern lifestyle, acting as strong epigenetic factors is strongly implicated in pathophysiology of conditions under IBS. Identifying and addressing food sensitivities in patients presenting with IBS like symptoms are currently underemphasised in clinical guidelines yet have the potential to provide major benefits for patients. Methods: Information was collected from the medical records of patients that were referred to the Gastroenterology Unit of Palmerston North DHB with unexplained gastrointestinal (GI) symptoms with or without other GI comorbidities between September 2018 and November 2021. Results: The main management option offered to the 121 patients included in this study, was lifestyle adjustment and/or a trial of 6 weeks, eliminating gluten and lactose from the diet. The most prevalent symptoms were abdominal pain 96/121 (79%), diarrhoea 83/121 (69%), followed by bloating and constipation. Seventy-eight patients had the outcomes of their improvement available. A total of 42 out of 78 patients (54%) were treated exclusively with gluten and lactose-free diet, in this group of patients 86% (36/42) reported a significant improvement in their symptoms with a score in the range of 40-100%. Conclusion: Our study illustrates the importance of focusing on triggering factors when assessing patients with IBS. We suggest that careful identifying and eliminating the triggering food antigens as monotherapy or in addition to the lifestyle adjustment where appropriate should be the main objective in symptomatic patients fulfilling the IBS diagnostic criteria. These combinations and holistic approach in treating IBS' patients' symptoms are less expensive, non-toxic, and highly effective in achieving optimal outcomes and improving these patient's quality of life.

Malabsorption of fermentable oligo-, di-, mono-saccharides and polyols (FODMAPs) in response to prolonged exercise may increase incidence of upper and lower gastrointestinal symptoms (GIS), which are known to impair exercise performance. This case study aimed to explore the impact of a low-FODMAP diet on exercise-associated GIS in a female ultraendurance runner diagnosed with irritable bowel syndrome, competing in a 6-day 186.7-km mountainous multistage ultramarathon (MSUM). Irritable bowel syndrome symptom severity score at diagnosis was 410 and following a low-FODMAP diet (3.9 g FODMAPs/day) it reduced to 70. The diet was applied 6 days before (i.e., lead-in diet), and maintained during (5.1 g FODMAPs/day) the MSUM. Nutrition intake was analyzed through dietary analysis software. A validated 100-mm visual analog scale quantified GIS incidence and severity. GIS were modest during the MSUM (overall mean ± SD: bloating 27 ± 5 mm and flatulence 23 ± 8 mm), except severe nausea (67 ± 14 mm) experienced throughout. Total daily energy (11.7 ± 1.6 MJ/day) intake did not meet estimated energy requirements (range: 13.9–17.9 MJ/day). Total daily protein [1.4 ± 0.3 g·kg body weight (BW)−1·day−1], carbohydrate (9.1 ± 1.3 g·kg BW−1·day−1), fat (1.1 ± 0.2 g·kg BW−1·day−1), and water (78.7 ± 6.4 ml·kg BW−1·day−1) intakes satisfied current consensus guidelines, except for carbohydrates. Carbohydrate intake during running failed to meet recommendations (43 ± 9 g/hr). The runner successfully implemented a low-FODMAP diet and completed the MSUM with minimal GIS. However, suboptimal energy and carbohydrate intake occurred, potentially exacerbated by nausea associated with running at altitude. [ABSTRACT FROM AUTHOR]

Wheat was first cultivated in the Fertile Crescent (South Western Asia) with a farming expansion that lasted from around 9000 BC to 4000 BC. Whilst humans have been exposed to wheat for around the last 10 000 years, humans have existed for greater than 2·5 million years. Therefore, wheat (and thereby gluten) are relatively new introductions to our diet! By the end of the 20th century, global wheat output had expanded by 5-fold, with a corresponding increase in the prevalence of gluten-related disorders. Coeliac disease (CD) is a state of heightened immunological responsiveness to ingested gluten in genetically susceptible individuals. CD now affects 1 % or more of all adults, for which the management is a strict lifelong gluten-free diet (GFD). However, there is a growing body of evidence to show that a far greater proportion of individuals without CD are self-initiating a GFD. This includes individuals initiating a GFD as a lifestyle choice, people with irritable bowel-type symptoms and those diagnosed with non-coeliac gluten (or wheat) sensitivity. Despite a greater recognition of gluten-related disorders, gaps still remain in our understanding of both their aetiology and management. This article explores the role of the gluten-free diet in gluten-related disorders, along with current uncertainties. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) is a functional digestive disorder that affects medical students at a higher rate than the general population. Intern doctors are the most affected class by IBS among medical students. Determining the prevalence of IBS and associated risk factors is essential for taking preventive measures. We aimed to investigate the prevalence and predictors of IBS among intern doctors in this study. This study was conducted using an online survey for intern doctors in the 2021-2022 academic year. Rome IV criteria were utilized for IBS diagnosis. Anxiety and depression scores were calculated according to the Hospital Anxiety and Depression Scale (HADS). The prevalence of IBS in the 249 participants was 31.7% included in this study. 32.1% of all participants had depression, 44.2% had anxiety, 65.1% had sleep disorders, 73.1% had MSE (medical specialty exam) anxiety, and 96% were concerned about carrying out the medical profession after graduating from university. Female gender (p<0.001), using regular medication (p=0.019), not exercising regularly (p=0.002), sleep disturbance (p<0.001), food hypersensitivity (p=0.001), having a history of severe acute gastroenteritis (AGE) before IBS symptoms started (p<0.001), IBS in first-degree relatives (p<0.001), be low income (p<0.001), having a divorced parent (p=0.008), not having siblings (p=0.002), severe emotional stress history in the last six months (p=0.004), having depression (p<0.001), having anxiety (p<0.001), and MSE anxiety (p<0.001) identified as risk factors associated with IBS. The multivariant analysis determined independent risk factors affecting the prevalence of IBS in intern doctors as female gender, depression, anxiety, and severe AGE history before IBS symptoms started. In this study, it was determined that approximately one-third of the interns were diagnosed with IBS. Stress management training can be considered to screen this group for IBS and psychological problems and to help them cope with these stressors. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) causes abdominal pain during bowel movements and is diagnosed according to the Rome IV international diagnostic criteria. Patients diagnosed as having IBS experience abdominal pain at least 1 day/week, on average, over a 3-month period and not 3 days per month. A diagnosis of IBS is confirmed if symptoms have persisted for more than 6 months. IBS symptoms negatively affect daily life. First, improving daily habits are important to ameliorating IBS symptoms. IBS symptoms can be alleviated by staying active, sleeping, resting and staying stress-free. In addition, it is important to eat three, balanced meals a day on a regular basis and avoid overeating, especially at night. Spicy foods, high-fat foods, and alcohol can exacerbate symptoms. Researchers found, in a literature review, that IBS symptoms can be ameliorated by improving daily habits, thus relieving abdominal pain and the defecation symptoms of IBS. [ABSTRACT FROM AUTHOR]

Study Question: Do the spectrum and prevalence of comorbidities of endometriosis and irritable bowel syndrome (IBS) overlap?Summary Answer: Despite several overlapping symptoms, the most significantly associated comorbidities of endometriosis and IBS are different and are rather related to the organ systems primarily involved in the index diagnosis.What Is Known Already: Endometriosis and IBS both have several similar unspecific symptoms, such as recurrent abdominal pain, cramping and anxiety, and both diseases affect young women and are associated with a number of comorbidities causing a poor quality of life. However, a detailed study, revealing the full spectrum of endometriosis and IBS comorbidities in the same study population, is lacking.Study Design, Size, Duration: This article presents a retrospective in silico analysis of the data from a large nationwide biobank-based cohort consisting of 121 773 women. After excluding all first- and second-degree relatives, the data of up to 65 421 women were analyzed.Participants/materials, Setting, Methods: International Classification of Disease-10 diagnosis main codes associated with endometriosis (N80) and IBS (K58) diagnoses were identified from the Estonian Biobank dataset by linking with the Estonian Health Insurance Fund and other relevant registries. The associations between N80 and K58 and other diagnosis codes were tested using logistic regression, adjusting for age at recruitment and 10 genetic principal components to account for potential population stratification. Bonferroni correction was applied to account for multiple testing.Main Results and the Role Of Chance: Both women with endometriosis and IBS suffered from more conditions compared to the control group, with 226 and 428 diagnosis codes statistically significantly more frequent in women with respective diagnosis compared to controls. Women suffering from both conditions had 275 significantly associated comorbidities. A remarkable proportion of women with IBS or endometriosis suffered also from endometriosis (9.0%) or IBS (13.6%), respectively. In endometriosis, the most prevalent diagnoses were related to diseases of the genitourinary system (33 N-category codes) and in women with IBS, the most associated diagnoses were related to digestive disorders and gastrointestinal tract (52 codes from K-category). Among the most significant diagnoses in endometriosis were uterine leiomyomas (D25), menstrual disorders (N92) and infertility (N97) (P < 1 × 10-315 for all), and in IBS, lactose intolerance (E73), gastritis and duodenitis (K29) and functional dyspepsia (K30) were in the top list of most significant comorbidities (P < 1 × 10-315 for all).Limitations, Reasons For Caution: The information about the severity stages of endometriosis and subtypes of IBS was not available for analysis. The findings may not be fully extrapolated to all female populations, because all participants were from one geographic area and had good access to health services.Wider Implications Of the Findings: These findings support previous studies that have found a high prevalence of pre-selected comorbidities in women with endometriosis and IBS. However, taking into account the differences in the full spectrum of comorbidities of endometriosis and IBS may aid in diagnosing these disorders. Women and healthcare providers need to be aware that women with endometriosis are at high risks of complications during pregnancy and should be carefully monitored.Study Funding/competing Interest(s): This research was funded by the Estonian Research Council (grant PRG1076), Horizon 2020 innovation grant (ERIN, grant no. EU952516), Enterprise Estonia (grant no.

Irritable bowel syndrome (IBS) is a chronic gastrointestinal (GI) disorder with no clear etiology. Current diagnostic and treatment standards are suboptimal. This review aimed to analyze current literature on the presence of GI dysbiosis in adults with IBS and the efficacy of probiotic treatment. Findings support an integrative IBS diagnostic and treatment strategy rooted in identifying GI dysbiosis and using non-pharmacologic probiotic treatment options. [ABSTRACT FROM AUTHOR]

Background. Hemogram parameters are not only diagnostic tools in haematological diseases, but their role in inflammatory conditions is also important. One of these haematological markers is a derived index, the so-called red cell distribution width-toplatelet count ratio (RPR). The role of RPR has been well established in various inflammatory conditions. Objectives. In the present study, we aimed to observe the RPR levels of patients with functional bowel disease (FBD), which is also considered as an inflammatory process, and to compare this to the healthy population. Material and methods. Patients diagnosed with FBD according to Rome IV criteria were included as the study group. Healthy volunteers were enrolled as control subjects. Patients with any form of anaemia or haematological disorders or inflammatory diseases were excluded. Age, gender and hemogram parameters were obtained from institutional databases. The data of the study and control groups was compared. Results. 158 subjects were enrolled in the study; 87 in the FBD group and 71 in the control group. The RPR of the FBD and control groups were 7% (2%) and 5% (1%), respectively. The difference in RPR between the FBD and control groups was statistically significant (p = 0.008). A RPR value higher than 6% has a 70% sensitivity and 52% specificity in detecting FBD. There was a significant and positive correlation between RPR levels and the presence of FBD (r = 0.22, p = 0.007). Conclusions. We suggest that elevated RPR levels could yield potential diagnostic benefits in the diagnosis of FBD. However, prospective studies with a larger population are needed to confirm our results.

Irritable bowel syndrome (IBS) is diagnosed based on clinical criteria of regular abdominal pain and disordered defaecation. If first-line treatments such as lifestyle changes fail, patients with diarrhoea-predominant IBS may respond to rifaximin, eluxadoline or, for women, alosetron, if tolerated. For constipation-predominant IBS, options are tegaserod for younger women, and the secretagogues linaclotide, plecanatide, lubiprostone and tenapanor. As IBS is a gut–brain interaction disorder, neuromodulators such as tricyclic antidepressants may help. [ABSTRACT FROM AUTHOR]

Irritable bowel syndrome (IBS) is a complex gastrointestinal disorder. There is increasing evidence linking changes in the gastrointestinal microbiota and IBS. Probiotics are living organisms and studies have shown that probiotic treatment may have positive effects in the gastrointestinal tract of IBS patients. The mechanism of action of probiotics in IBS is complex. The aim of this review is to summarise the mechanisms of probiotics in the treatment of IBS. [ABSTRACT FROM AUTHOR]

Background: Irritable bowel syndrome (IBS) represents the most common functional disorder of the gastrointestinal tract. Many patients with IBS display complex gastrointestinal (GI) symptoms leading to overlapping diagnosis of IBS and other GI diseases in many patients.Methods: Using the Disease Analyzer database (IQVIA) featuring patients treated within 2010 and 2019 within 1240 general practices in Germany, we analyzed the prevalence of common GI diseases within 12 months prior to and after the first diagnosis of IBS.Results: 65,569 patients with an initial diagnosis of IBS were included into the analysis. Out of these, 29,553 patients had an observation time of at least 12 months prior to the first IBS diagnosis and at least 12 months after the first IBS diagnosis. Mean age was 48.8 (SD: 18.4) years, 65.0% were female. Notably, 16,164 (55%) of these patients had at least one preexisting diagnosis of another GI diseases within 12 months prior to the first IBS diagnosis. Most common overlapping diagnoses were intestinal infectious diseases (26%), gastritis/ duodenitis (21%), diseases of the esophagus (15%), non-infectious enteritis or colitis (7.4%), functional dyspepsia (6%) and ulcers (1.0%). Additionally, 12,048 (41%) received one of these diagnosis within 12 months after the first IBS diagnosis.Conclusion: Our data provide evidence for a high overlap between IBS and other GI diagnoses. Moreover, we show that IBS is frequently diagnosed in patients with preexisting GI diseases, potentially putting into question the validity of IBS diagnosis at least in some cases.

Migraine is a primary headache disorder with a prevalence of 11.6% globally and 27% in Saudi Arabia. Irritable bowel syndrome (IBS) has a prevalence of 9.2% worldwide. The prevalence of IBS has not been established nationally. However, provincial studies for migraine and IBS have been conducted nationwide. There is a significant link between migraine and IBS globally. Migraineurs had a considerably greater prevalence of IBS than nonmigraineurs (OR = 2.49 , 95% CI 2.22-2.78). Patients with IBS have 60% higher odds for migraines. This identifies an association that needs to be investigated in a nationwide manner. The study has two main aims. The first is to measure the prevalence of migraine and irritable bowel syndrome in Saudi Arabia. The second is to observe the association and the relationship between migraine and irritable bowel syndrome in Saudi Arabia. A cross-sectional study was conducted among the general population of Saudi Arabia between March 2021 and June 2021, whose ages are 15 years old or greater. Participants filled an online self-administered survey. The data collection tools included the Migraine Screen Questionnaire (MS-Q) for migraine symptoms, migraine severity (MIGSEV) scale for severity of migraine, and the IBS module of the Rome IV Diagnostic Questionnaire (R4DQ) for IBS symptoms and their subtype. With 2802 participants, the majority of the study samples were males, who constituted 52.5%. Among the study's sample, the prevalence of migraine consisted of 27.4%, and the prevalence of IBS was 16.4%. The odds of having IBS in migraineurs were much higher than in those without migraine (OR 4.127; 95% CI 3.325-5.121), and the association was statistically significant (p < 0.001). In conclusion, there is a strong association between migraine and irritable bowel syndrome in Saudi Arabia. [ABSTRACT FROM AUTHOR]

Background/Aims: Substantial proportions of patients with constipation-predominant irritable bowel syndrome (IBS-C) linked their symptoms with particular intake of foods. However, there is lack of current data regarding the intake among IBS-C patients before any dietary interventions. Thus, this study aimed to evaluate the dietary adequacy among IBS-C against the standard recommended nutrient intake (RNI) and healthy controls. Methods: A retrospective case-control study was conducted involving IBS-C patients and healthy control subjects. A validated 126-food items frequency questionnaire was administered to all the subjects to assess their dietary intake, guided by dietitians. The calculated nutrients intake for IBS-C patients was then compared against the standard RNI and healthy controls. Results: A total of 306 subjects were recruited, among which 218 were diagnosed with IBS-C and 88 were included as healthy controls. IBS-C patients had significantly lower intake of wholegrain products, fried foods, dairy products, fruits, and vegetables compared to healthy controls. The daily intake of energy, certain macronutrients, and micronutrients among IBS-C patients was significantly lower than the healthy subjects. Less than 5% of IBS-C patients and healthy subjects achieved the standard recommendation for dietary fiber. Also, various vitamin intake (B1, B2, B6, folate, B12, E, K, and potassium) among IBS-C patients did not meet the standard RNI. Conclusions: Dietary intakes of IBS-C patients did not meet the recommended intake for Malaysian and showed the nutritional inadequacies compared to the control subjects. Our study highlighted the importance of dietary evaluation prior to planning strategies for dietary intervention targeting IBS-C patients. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study is to evaluate the relationship between irritable bowel syndrome (IBS) and abdominal obesity. Patients and Methods: This is a cross-sectional study, consisting of 18-49 year old patients who applied to Marmara University School of Medicine's Family Medicine outpatient clinics and who accepted to participate. A questionnaire was applied using face-to-face interview technique; anthropometric measurements were obtained as recommended by World Health Organization (WHO). The diagnosis of IBS was made for those who fully met the diagnostic criteria of ROME IV-IBS and had no alarm symptoms. Abdominal obesity of the participants was determined via anthropometric measurements. Statistical analyses were performed by using SPSS 20 package program. Results: A total of 487 patients participated in the study: 77% female, 33% male; mean age value 33.71±8.59 years. The prevalence of IBS was 24.2% (n=118) [F:27.2% (n=102), M:14.3% (n=16)]. Abdominal obesity prevalence was 31.2% (n=152) [F:24.5% (n=92, M:53.6% (n=60)]. There is no statistically significant difference in terms of abdominal obesity with and without IBS (p>0.05). Conclusion: In this study no statistically significant relationship has been detected between IBS and abdominal obesity. [ABSTRACT FROM AUTHOR]

Background: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders in clinical practice. IBS diagnosis is based on symptoms defined by abdominal pain or discomfort associated with defecation or changes in bowel habits. Gut-brain interaction caused by stress or depressive emotion is one of the essential pathologies. Acupuncture has been used for the treatment of internal medicine, including digestive disorders and depressive disorders in Chinese medicine. This study aims to determine whether electro-acupuncture could have significant benefits than sham acupuncture for IBS.Methods/design: This is a single-blinded randomized sham-controlled clinical trial with two arms. A total of 120 IBS patients will be recruited. After a 2-week run-in period, eligible subjects will be randomly assigned to one of two arms, acupuncture (AC) arm and sham acupuncture (SAC) arm. Each eligible subject will go through a 2-week run-in-period, 6-week treatment period, and 6-week follow-up period. Five visits in total were scheduled for each subject in week 0, week 2, week 5, week 8, and week 14. The outcomes would be measured with (1) IBS-SSS, (2) Hamilton Depression Rating Scale (HAMD-17), (3) Clinical Global Impression-Severity (CGI-S), (4) Self-Rating Depression Scale (SDS), and (5) IBS Quality of Life (IBS-QoL).Discussion: The study will compare electro-acupuncture with sham acupuncture to explore the feasibility of electro-acupuncture in improving IBS symptoms.Trial Registration: ClinicalTrials.gov NCT04387383 .

Campylobacter enterocolitis may lead to post-infection irritable bowel syndrome (PI-IBS) and while some C. jejuni strains are more likely than others to cause human disease, genomic and virulence characteristics promoting PI-IBS development remain uncharacterized. We combined pangenome-wide association studies and phenotypic assays to compare C. jejuni isolates from patients who developed PI-IBS with those who did not. We show that variation in bacterial stress response (Cj0145_phoX), adhesion protein (Cj0628_CapA), and core biosynthetic pathway genes (biotin: Cj0308_bioD; purine: Cj0514_purQ; isoprenoid: Cj0894c_ispH) were associated with PI-IBS development. In vitro assays demonstrated greater adhesion, invasion, IL-8 and TNFα secretion on colonocytes with PI-IBS compared to PI-no-IBS strains. A risk-score for PI-IBS development was generated using 22 genomic markers, four of which were from Cj1631c, a putative heme oxidase gene linked to virulence. Our finding that specific Campylobacter genotypes confer greater in vitro virulence and increased risk of PI-IBS has potential to improve understanding of the complex host-pathogen interactions underlying this condition. Stephanie Peters, Ben Pascoe, et al. use whole-genome sequencing and phenotypic analysis of clinical strains from patients to identify potential genetic factors involved in irritable bowel syndrome resulting from Campylobacter jejuni infection. Their data suggest that genes involved in the bacterial stress response and biosynthetic pathways may contribute toward irritable bowel syndrome, providing further insight into links between Campylobacter genotypes and risk of disease.

Background: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common chronic digestive disease. Recent observational studies have reported that the Chinese herbal formula Huoxiang Zhengqi (HXZQ) can relieve IBS-D symptoms, but no high-level evidence is presented. Therefore, we want to evaluate the efficacy and safety of HXZQ for IBS-D patients.Methods: This is a double-blind, randomized, placebo-controlled trial. The 212 eligible patients with IBS-D will be randomly assigned to receive either HXZQ oral liquid or a placebo, at a 1:1 ratio, for 4 weeks with a 4-week follow-up period. Adequate relief will be the primary outcome measures. IBS symptom severity score, IBS quality-of-life questionnaire, EQ-5D-5L, and Chinese medicine symptom questionnaire will be the secondary outcome measures.Discussion: This trial aims to demonstrate the efficacy and safety of HXZQ for IBS-D, which is expected to be an effective IBS-D treatment.Trial Registration: The trial was registered with the Chinese Clinical Trial Registry, ChiCTR1900026837 .

INTRODUCTION: Psychological comorbidities are associated with irritable bowel syndrome (IBS), but little is known about their cumulative effect on its prognosis. We examined this issue in a longitudinal 12-month follow-up study. METHODS: We collected complete demographic, symptom, and psychological comorbidity data (anxiety, depression, somatic symptom disorder, perceived stress, and gastrointestinal symptom-specific anxiety) at baseline from 807 adults who met Rome IV criteria for IBS. At 12 months, we collected data regarding IBS symptom severity and impact, consultation behavior, and treatments commenced from 452 individuals successfully followed up. We examined the cumulative effects of psychological comorbidities at baseline on subsequent IBS disease behavior. RESULTS: At baseline, among the 807 participants, 177 (21.9%) had 1, 139 (17.2%) 2, 103 (12.8%) 3, 89 (11.0%) 4, and 54 (6.7%) 5 psychological comorbidities. IBS symptom severity at baseline increased significantly with the number of psychological comorbidities (72.2% of those with 5 psychological comorbidities reported severe symptoms, vs 29.1% of those with none, P < 0.001). Among 452 (56.0%) participants followed up at 12 months, those with a higher number of psychological comorbidities at baseline were significantly more likely to have seen a gastroenterologist (33.3% of those with 5 psychological comorbidities, vs 21.4%of those with none, P50.001), cycle through more treatments (P < 0.0001), to report more severe IBS symptoms (66.7% with 5, vs 24.4% with none, P < 0.001) and continuous abdominal pain (22.1% with none, vs 61.9%with 5, P < 0.001), and to report that symptoms impacted on daily activities -50% of the time (90.5% with 5, vs 41.2% with none, P < 0.001). DISCUSSION: The prognosis of individuals with Rome IV-defined IBS worsens according to incremental increases in psychological comorbidity. This has important clinical and research implications.

The article discusses the 2021 guidelines by the British Society of Gastroenterology (BSG) and the American College of Gastroenterology (ACG) emphasize the importance of primary care physicians in the initial diagnosis and management of Irritable bowel syndrome. Topics include the healthcare's system facility present for the prevalence of IBS; screening for other comorbidities, and requirement of effective doctor–patient relationship for the treatment of the disease.

Importance: The prevalence of irritable bowel syndrome (IBS) in the United States is between 7% and 16%, most common in women and young people, with annual direct costs estimated at more than $1 billion dollars in the United States. Traditionally, the diagnosis of IBS has been based on the positive identification of symptoms that correlate with several different syndromes associated with disorders such as IBS diarrhea, IBS constipation, functional diarrhea, functional constipation, chronic functional abdominal pain, or bloating. Several peripheral and central mechanisms initiate gastrointestinal motor and sensory dysfunctions leading to IBS symptoms. Those dysfunctions may require evaluation in patients whose symptoms do not respond to first-line treatments.Observations: Validation studies of consensus symptom-based criteria have identified deficiencies that favor a simpler identification of the predominant symptoms of abdominal pain, bowel dysfunction, and bloating and exclusion of alarm symptoms such as unintentional weight loss, rectal bleeding, or recent change in bowel function. Symptom-based diagnosis of IBS is enhanced with additional history for symptoms of somatoform and psychological disorders and alarm symptoms, physical examination including digital rectal examination, and screening tests to exclude organic disease (by measuring hemoglobin and C-reactive protein concentrations). The initial treatment plan should include patient education, reassurance, and first-line treatments such as fiber and osmotic laxatives for constipation, opioids for diarrhea, antispasmodics for pain and for management of associated psychological disorders. For patients who do not respond to those IBS treatments, testing for specific functional disorders may be required in a minority of patients with IBS. These disorders include rectal evacuation disorder, abnormal colonic transit, and bile acid diarrhea. Their identification is followed by individualized treatment, such as pelvic floor retraining for rectal evacuation disorders, sequestrants for bile acid diarrhea, and secretory agents for constipation, although there is only limited evidence that this individualized management approach is effective.Conclusions and Relevance: Advances in the identification of specific dysfunctions as causes of individual symptoms in the "IBS spectrum" leads to the potential to enhance the diagnosis and management of symptoms for the majority of patients for whom first-line therapies of IBS and management of comorbid psychological disorders are insufficient.

INTRODUCTION: Irritable bowel syndrome (IBS) is a chronic functional bowel disorder, which follows a relapsing and remitting course. Little is known about how evolving definitions of IBS or treatment for the condition affect symptom stability. We conducted a 12-month longitudinal follow-up study of individuals who self-identified as having IBS to examine these issues. METHODS: We collected demographic, gastrointestinal symptom, mood, and psychological health data at baseline, and gastrointestinal symptom data at 12 months, fromadults who self-identified as having IBS, registered with 3 organizations providing services to people with IBS. We applied the Rome III and Rome IV criteria simultaneously at baseline and 12months and subtyped participants according to predominant stool form or frequency. We examined stability of a diagnosis of IBS, and stability of IBS subtype, for the Rome IV and III criteria separately and examined the effect of commencing new therapy on fluctuation of symptoms. RESULTS: Of 1,375 individuals recruited at baseline, 784 (57.0%) provided data at 12 months. Of these, 452 met the Rome IV criteria for IBS at baseline, of whom 133 (29.4%) fluctuated to another functional bowel disorder at 12 months. In the remaining 319 (70.6%) who still met the Rome IV criteria for IBS, IBS subtype changed in 101 (31.7%) subjects, with IBS with mixed bowel habit (IBS-M) the least stable. Commencing a new treatment for IBS did not affect symptom stability. Among 631 who met the Rome III criteria at baseline responding at 12 months, 104 (16.5%) fluctuated to another functional bowel disorder. In the 527 (83.5%) who still met the Rome III criteria for IBS, IBS subtype fluctuated in 129 (24.5%), with IBS-M the most stable subtype. Again, commencing a new treatment for IBS did not affect symptom stability. DISCUSSION: Fluctuation between functional bowel disorders and predominant stool subtype is common in people with IBS and does not appear to be influenced solely by treatment. Rome IV IBS appears less stable than Rome III IBS. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Immediate-release (IR) formulation of linaclotide 290 mg improves abdominal pain and constipation (APC) in patients with irritable bowel syndrome (IBS) with constipation. Delayed-release (DR) formulations were developed on the premise that targeting the ileum (delayed-release formulation 1 [DR1]) or ileocecal junction and cecum (MD-7246, formerly DR2) would modulate linaclotide's secretory effects while preserving pain relief effects. METHODS: This phase 2b study randomized patients with IBS with constipation to placebo or 1 of 7 once-daily linaclotide doses (DR1 30, 100, or 300 mg; MD-7246 30, 100, or 300 mg; or IR 290 mg) for 12 weeks. Key efficacy endpoints were change from baseline in abdominal pain and complete spontaneous bowel movement frequency, and 6/12-week combined APC11 responder rate. RESULTS: Overall, 532 patients were randomized; mean age was 45.1 years, and most were women (83.3%) and White (64.7%). All linaclotide DR1 and MD-7246 groups experienced greater improvements in abdominal pain from baseline and vs placebo throughout treatment. Linaclotide DR1 and IR led to numerically greater improvements from baseline in complete spontaneous bowel movement frequency and higher APC+1 responder rates compared with placebo; MD-7246 results were similar to placebo. Diarrhea was the most common adverse event with DR1 and IR; rates were similar between MD-7246 and placebo. DISCUSSION: Altering the site of drug delivery in the intestine might uncouple linaclotide's pain relief from secretory effects. Persistent, modest abdominal pain improvement with limited impact on bowel symptom parameters, as seen across MD-7246 doses, warrants further study of MD-7246 as a novel treatment for abdominal pain, regardless of IBS subtype.

INTRODUCTION: Conventionally, patients with irritable bowel syndrome (IBS) are subgrouped based on their predominant bowel habit. Given the relevance of psychological comorbidity to IBS symptoms, our aim was to explore an alternative approach to subgrouping by incorporating factors beyond stool form and frequency. METHODS: We collected demographic, symptom, and psychological health data from 1,375 adult subjects in the community who self-identified as having IBS, identifying 2 cohorts meeting either Rome III or Rome IV criteria. In each cohort, we performed latent class analysis, a method of model-based clustering, to identify specific subgroups (clusters). For each cluster, we drewa radar plot and compared these by visual inspection, describing cluster characteristics. RESULTS: In total, 1,080 individuals met the Rome III criteria for IBS, and 811 met the Rome IV criteria. In both cohorts, a 7-cluster model was the optimum solution, and the characteristics of the clusters were almost identical between Rome III and IV. Four clusterswere defined by the pattern of gastrointestinal symptoms (loose stools and urgency or hard stools and bloating), further differentiated by the presence of abdominal pain not relieved by defecation, and by the extent of psychological comorbidity. Two clusters had belowaverage gastrointestinal symptoms, differentiated by the extent of psychological comorbidity. The final cluster had well-above-average gastrointestinal symptoms and high levels of psychological comorbidity. The proportion of subjectswith severe IBSsymptomscores, high levels of perceivedstress, and high levels of gastrointestinal symptom--specific anxiety was significantly higher in clusters with high psychological comorbidity (P < 0.001). DISCUSSION: Latent class analysis identified 7 distinct IBS subgroups characterized by varying degrees of gastrointestinal symptoms, extraintestinal symptoms, and psychological comorbidity. Further research is needed to assess whether they might be used to direct treatment. [ABSTRACT FROM AUTHOR]
