Background and Aim: Irritable bowel syndrome (IBS) is a complex and heterogeneous disorder. Sensory, motor and barrier dysfunctions are the key physiological endophenotypes of IBS. Our aim is to review studies evaluating barrier dysfunction in adults and children with IBS, as well as to link those changes with IBS symptomatology and quality of life. Methods: A comprehensive and systematic review of multiple databases was performed up to March 2020 to identify studies comparing intestinal permeability in IBS patients with healthy controls. Both in vivo and in vitro studies were considered. Results: We identified 66 studies, of which 27 used intestinal probes to quantify barrier function. The prevalence of barrier dysfunction differed between PI-IBS (17–50%), IBS-D (37–62%) and IBS-C (4–25%). At a group level, permeability was increased compared with healthy controls in IBS-D (9/13 studies) and PI-IBS (4/4 studies), but only a minority of IBS-C (2/7 studies) and not in the only IBS-M study. All four studies in children with IBS demonstrated loss of barrier function. A heterogeneous set of tight junction genes were found to be altered in small and large intestines of adults with IBS, but these have not been evaluated in children. Positive associations were identified between barrier dysfunction and bowel disturbances (6/9 studies), abdominal pain (9/13 studies), overall symptom severity (1/6 studies), depression and anxiety (1/1 study) and quality of life (1/4 studies). Fecal slurry or supernatants of IBS patients were found to induce barrier disruption in animal models (5/6 studies). Conclusions: Barrier dysfunction is present in a significant proportion of adult and all pediatric IBS studies, especially in the IBS-D and PI-IBS subtype. The majority of studies indicated a positive association between loss of barrier function and symptoms such as abdominal pain and changes in the bowel function.

Background: Irritable bowel syndrome (IBS) is a common, chronic and sometimes disabling functional disorder of the gastrointestinal system and its treatment remains as health problem. Thus the aim of this study was to evaluate the Effect of multispecies probiotic supplementation, as a novel and Controversial therapeutic method on Irritable bowel syndrome. Materials and Methods: In this randomized double blind Placebo-controlled clinical trial, 60 patients with IBS were enrolled. The patients were divided randomly into two groups. Patients in intervention group received two 500 mg probiotic capsules (Familact®) and in control group, received two 500 mg placebo capsules daily for 30 consecutive days. The symptoms and quality of life were measured and compared at the beginning and just after the end of study for each case. Results: Results showed the mean score of Abdominal pain after 1 month of treatment in the probiotic group was significantly lower than the control group (1.76 ± 2.04 vs. 2.88 ± 2.25, P=0.049, respectively). While, other symptoms and quality of life did not change significantly (P>0.05). Furthermore, defecation habit and global symptoms improvement was similar after intervention in both groups and we did not observe significant differences in these items (P>0.05). Conclusion: The results of this study showed the beneficial effects of multispecies probiotic supplementation in controlling IBS patients’ abdominal pain. thus it can be prescribed as a therapeutic option in addition to standard therapy and significantly lead to better control of this symptom in the short term.

Several studies have reported some efficacy of diets low in fermentable carbohydrates (Fermentable Oligo-, Di-, Monosaccharides and Polyols (FODMAPs)) in Irritable Bowel Syndrome (IBS). There is no evidence of its superiority compared to gluten-free and balanced diets in improving IBS patients’ quality of life (QoL). The aim of this study is to assess whether different diets can improve QoL in IBS. Forty-two patients with IBS, according to Rome IV criteria, were enrolled. Low-FODMAP, gluten-free and balanced diets were proposed to each patient in the same succession. Each diet was followed for 4 weeks. The Bristol Stool Scale, the Visual Analogue Scale (VAS) for bloating and abdominal pain, and the SF12 questionnaire for health-related quality of life were applied at the beginning and at the end of each diet. Twenty-eight of the forty-two patients completed all the three diets. All the three diets reduced symptom severity (p < 0.01), bloating (p < 0.01) and abdominal pain (p < 0.01), and improved quality of life (p < 0.05); 3% of patients expressed a preference for the low-FODMAP diet, 11% for the gluten-free and 86% for the balanced diet (p < 0.01). The balanced diet improves QoL and VAS pain, provides an adequate quantity of FODMAPs and is more appreciated by patients. For these reasons, the balanced diet could be recommended to patients with irritable bowel syndrome.

Irritable bowel syndrome is characterized by recurrent abdominal pain and altered bowel function. In designing studies to evaluate new treatments for this disease, however, it is difficult to select appropriate endpoints to reflect improvement in the range of symptoms of the syndrome. In the present study we evaluated the parameter of adequate relief of abdominal pain and discomfort, as perceived by the patients, as a key endpoint for efficacy in the treatment of patients with irritable bowel syndrome. Abdominal pain and bowel function data were collected daily from 370 patients with the disease during treatment with placebo or a novel potent 5HT3 receptor antagonist. Once every 7 days adequate relief of pain and discomfort was assessed. Quality-of-life data were collected using self-administered questionnaires. The endpoint of adequate relief was significantly ( P < 0.05) correlated with improvement in pain severity scores, percentage of pain-free days, percentage of days with urgency, improvement in stool frequency and consistency, and quality-of-life parameters. Adequate relief of pain and discomfort is significantly correlated with changes in multiple parameters associated with irritable bowel syndrome and can be used as an endpoint for assessing response to therapy in these patients.

Abstract The effects of propolis, a well-known functional food, on irritable bowel syndrome (IBS), a chronic gastrointestinal disorder, in humans have yet to be investigated. This study evaluated propolis effects in IBS subjects. In this clinical study, 56 patients with IBS diagnosed by Rome IV criteria were assigned for 6 weeks randomly to the study groups. At the baseline and endpoint phase, patients’ gastrointestinal symptoms, quality of life (QOL), anxiety state, dietary intakes, and anthropometric indices were assessed. Independent t-test, paired t-test, Mann-Whitney U test, Wilcoxon, Fisher's exact test, repeated measures analysis of variance and logistic regression test were used for analyzing the data. To adjust the effect of confounders, covariance analysis was used. The results of this study showed that after modulating the effect of potential confounders, propolis supplementation increased the chance of improving IBS severity by 6.22 (with a confidence interval of: 1.33 - 1.14 and P = 0.035). A significant abdominal pain improvement, anxiety state, and bowel habits dissatisfaction reduction was observed within- and between-group differences in propolis group compared to the placebo group (P = 0.040, P = 0.035, P = 0.029, retrospectively). The overall score of quality of life and its domains in the propolis group was statistically significant, but in comparison between the two groups, this difference was not significant. Also, regards to the food intakes and anthropometric indices, there were no significant differences between and within the two study groups. This study illustrated that propolis supplementation could be used as adjunctive therapy in IBS disease to reduce abdominal pain and anxiety state.

Irritable Bowel

Irritable bowel syndrome (IBS) is one of the most common disorders of the gut-brain axis, which affects approximately 4% of the global population. The Rome IV criteria define IBS as chronic or recurrent abdominal pain associated with altered bowel habits. Patients can be categorized in four subtypes: IBS with predominant constipation (IBS-C), predominant diarrhea (IBS-D), mixed bowel habits (IBS-M), and unclassified (IBS-U). IBS is associated with a lower quality of life, reduced work productivity, and high healthcare costs. When comparing subtypes, patients with IBS-D report lower disease related quality of life. Due to the scope of this review, we have solely focused on patients with IBS-D. Choosing the right pharmacological treatment in these patients remains challenging due to the heterogeneous patient population, patients’ expectation of the treatment outcome, unavailability of efficacious drugs, and the multifactorial and incompletely understood underlying pathophysiology. Currently, pharmacological treatment options target individual symptoms, such as abdominal pain, altered bowel habits, and bloating. In this review, we aimed to summarize the current and recent pharmacological treatment options in IBS-D, targeting the predominant gastrointestinal symptoms. Additionally, we proposed a pharmacological treatment algorithm which healthcare professionals could use when treating individual patients with IBS-D.

Background and Aims: Irritable bowel syndrome (IBS) is associated with a high prevalence of psychiatric comorbidities. While psychosocial determinants were intently studied, coping strategies with stress used by IBS patients were never comprehensively reviewed. Therefore, this systematic review aimed to summarize the coping strategies used by IBS patients and to identify which tools are frequently used to measure coping strategies. Methods: According to PRISMA guidelines, we searched for articles indexed in PubMed, EBSCOhost, EMBASE and Cochrane Library. The search terms included: (coping OR coping strategies OR coping mechanism) AND (irritable bowel syndrome OR IBS). The initial search identified 756 articles. After applying all filters (human filters, excluding conference abstracts and conference papers), 96 studies remained. Finally, a total of 21 articles were included in this systematic review. Results: Twenty-one articles using fifteen coping instruments and six measures of quality of life were found. One was interventional, one longitudinal, and the rest were cross-sectional studies. One study was qualitative, while the rest used quantitative measures. Emotion-focused coping was associated with worse psychological outcomes, while the effect of problem-focused coping was not regularly associated with better psychological outcomes. Catastrophizing was negatively associated with health-related quality of life. Psychological distress (anxiety, depression) was significantly related to the impairment of health-related quality of life. Conclusion: Patients with IBS cope in different ways when confronted with health and daily-life stressors. The maladaptive strategy of coping is associated with poor health-related quality of life and psychiatric comorbidities but methodological problems limit conclusions regarding the strength and nature of this association. Future research needs to focus on which strategies are most effective at reducing psychological distress in IBS patients.
