Irritable bowel disease

Jacopo Celli, Gudrun Rappold, Beate Niesler
Serotonin type 3 (5-HT3 ) receptors are ligand-gated ion channels formed by five subunits (5-HT3 A-E), which are encoded by the HTR3A, HTR3B, HTR3C, HTR3D and HTR3E genes. Functional receptors are pentameric complexes of diverse composition. Different receptor subtypes confer a predisposition to nausea and vomiting during chemotherapy, pregnancy, and following surgery. In addition, different subtypes contribute to neurogastroenterologic disorders such irritable bowel syndrome (IBS) and eating disorders as well as comorbid psychiatric conditions...

The gastrointestinal tract consists of an enormous surface area that is optimized to efficiently absorb nutrients, water, and electrolytes from food. At the same time, it needs to provide a tight barrier against the ingress of harmful substances, and protect against a reaction to omnipresent harmless compounds. A dysfunctional intestinal barrier is associated with various diseases and disorders. In this review, the role of intestinal permeability in common disorders such as infections with intestinal pathogens, inflammatory bowel disease, irritable bowel syndrome, obesity, celiac disease, non-celiac gluten sensitivity, and food allergies will be discussed...

BACKGROUND/AIMS: To determine the proportion of T-regulatory cells (CD4(+)CD25(high)FOXP3(+) cells) in peripheral blood and the number of FOXP3(+) cells in intestinal mucosa of children with inflammatory bowel disease (IBD), and to verify whether these parameters correlate with the activity of the disease. MATERIAL AND METHODS: 24 patients newly diagnosed for IBD were included in the study: ulcerative colitis (UC; n = 13) and Crohn's disease (CD; n = 11). Seventeen healthy controls (HC) and 16 patients with irritable bowel syndrome (IBS) served as a control group for peripheral and intestinal Tregs assessment, respectively...

Anecdotal and scientific evidence suggests that Cannabis use may be beneficial in inflammatory bowel disease (IBD) patients. Here, we have investigated the effect of a standardized Cannabis sativa extract with high content of cannabidiol (CBD), here named CBD BDS for "CBD botanical drug substance," on mucosal inflammation and hypermotility in mouse models of intestinal inflammation. Colitis was induced in mice by intracolonic administration of dinitrobenzenesulfonic acid (DNBS). Motility was evaluated in the experimental model of intestinal hypermotility induced by irritant croton oil...

Background/Aims: Several studies have demonstrated that sleep problems are associated with functional gastrointestinal disorders (FGIDs), such as irritable bowel syndrome (IBS), and functional dyspepsia etc, but the relationship between excessive daytime sleepiness (EDS) and FGIDs has not been systematically studied in general population. This study aimed to explore the relationship between EDS and specific types of FGIDs and the effect of the number of FGIDs on EDS. Methods: A sample of 3600 individuals (aged 18-80 years) was selected from 5 regions in China using a randomized stratified multi-stage sampling method...

OBJECTIVES: Celiac disease (CD) and irritable bowel syndrome (IBS) share similar symptoms, leading to confusion between the two and diagnostic delay. International guidelines recommend screening individuals with IBS for CD, via serological testing. However, studies published recently have cast doubt on the utility of this. We updated a previous meta-analysis examining this issue. METHODS: MEDLINE, EMBASE, and EMBASE Classic were searched through to May 2016. Eligible studies recruited adults with IBS according to symptom-based criteria, physician's opinion, or questionnaire data...

BACKGROUND: Ghrelin levels and obestatin/ghrelin ratio have been proposed as activity markers in ulcerative colitis, but no data are available in celiac disease (CD) and irritable bowel syndrome (IBS). Our aims were as follows: (a) to assess obestatin and ghrelin concentrations in adult active CD patients, diarrhea-predominant IBS (IBS-d), and healthy controls (HC) in relation to intestinal permeability; (b) to evaluate the ghrelin-obestatin profile in CD patients after a 1-year gluten-free diet (GFD); and (c) to establish the impact of ghrelin genetics...

The barrier function of the intestine is essential for maintaining the normal homeostasis of the gut and mucosal immune system. Abnormalities in intestinal barrier function expressed by increased intestinal permeability have long been observed in various gastrointestinal disorders such as Crohn's disease (CD), ulcerative colitis (UC), celiac disease, and irritable bowel syndrome (IBS). Imbalance of metabolizing junction proteins and mucosal inflammation contributes to intestinal hyperpermeability. Emerging studies exploring in vitro and in vivo model system demonstrate that Rho-associated coiled-coil containing protein kinase- (ROCK-) and myosin light chain kinase- (MLCK-) mediated pathways are involved in the regulation of intestinal permeability...

Probiotics are live, nonpathogenic bacteria capable of colonizing the colonic mucosa. The most common probiotics include strains of Lactobacillus or Bifidobacteria, which are part of the normal gastrointestinal microbiota. Initial studies of selected probiotic species have suggested potential efficacy in several gastrointestinal diseases including inflammatory bowel diseases (particularly pouchitis), antibiotic-related diarrhea, Clostridium difficile toxin-induced colitis, infectious diarrhea, irritable bowel syndrome, and allergy...

Diverticular disease (DD) is a common gastrointestinal condition. Clinical spectrum ranges from asymptomatic diverticulosis to symptomatic uncomplicated or complicated DD. Symptoms related to uncomplicated DD are not specific and may be indistinguishable from those of irritable bowel syndrome. Low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors potentially contributing to symptoms. Probiotics may modify the gut microbial balance leading to health benefits...

5-Hydroxytryptamine (5-HT) produced by enterochromaffin (EC) cells is an important enteric mucosal signaling ligand and has been implicated in several gastrointestinal diseases, including inflammatory bowel disease and functional disorders such as irritable bowel syndrome. The present study reports a new, simple and rapid visualization method of 5-HT-producing EC cells utilizing detection of autofluorescence in paraffin-embedded tissue sections after formalin fixation. In human samples, there was a high incidence of autofluorescence+ cells in the 5-HT+ cells in the pyloric, small intestinal and colonic glands, while co-localization was lacking between autofluorescence+ and gastrin+ cells in the pyloric and small intestinal glands...

Increasing evidence indicates a strong link between intestinal health and bone health. For example, inflammatory bowel disease can cause systemic inflammation, weight loss and extra-intestinal manifestations such as decreased bone growth and density.  However, the effects of moderate intestinal inflammation without weight loss on bone health have never been directly examined; yet this condition is relevant not only to IBD but to conditions of increased intestinal permeability and inflammation as seen with ingestion of high fat diets, intestinal dysbiosis, irritable bowel syndrome, metabolic syndrome and food allergies...

BACKGROUND: A possible association between dry eye disease (DED) and irritable bowel syndrome (IBS) has been hypothesized based on the fact that they both share an inflammatory pathogenesis. METHODS: Ninety-five patients with IBS and 276 healthy controls were enrolled in the study. All patients answered a questionnaire regarding DED symptoms and had a complete ophthalmic examination. DED signs were evaluated using Schirmer's 1 and tear break-up time (tBUT) tests in both groups...

Functional bowel disorders (FBDs), mainly irritable bowel syndrome (IBS) and functional constipation (FC, also called chronic idiopathic constipation), are highly diffused worldwide. Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, although less common, has a strong impact on patients' quality of life, as well as is highly expensive for our healthcare. A definite cure for those disorders is still yet to come. Over the years, several therapeutic approaches complementary or alternative to traditional pharmacological treatments, including probiotics, prebiotics, synbiotics, fiber and herbal medicinal products, have been investigated for the management of both groups of diseases...

AIM: To evaluate the perspective of gastroenterologists regarding the impact of fecal calprotectin (FC) on the management of patients with inflammatory bowel disease (IBD). METHODS: Patients with known IBD or symptoms suggestive of IBD for whom the physician identified that FC would be clinically useful were recruited. Physicians completed an online "pre survey" outlining their rationale for the test. After receipt of the test results, the physicians completed an online "post survey" to portray their perceived impact of the test result on patient management...

Migraine is a recurrent and commonly disabling primary headache disorder that affects over 17% of women and 5%-8% of men. Migraine susceptibility is multifactorial with genetic, hormonal and environmental factors all playing an important role. The physiopathology of migraine is complex and still not fully understood. Many different neuropeptides, neurotransmitters and brain pathways have been implicated. In connection with the myriad mechanisms and pathways implicated in migraine, a variety of multisystemic comorbidities (e...

Irritable bowel syndrome (IBS) is a chronic disease that needs special self-care strategies. The current study aimed at determining the effects of a self-care program on the severity of symptoms and quality of life of patients with IBS. In this randomized controlled clinical trial, 119 patients were randomly assigned to the experimental (n = 60) and control (n = 59) groups. Patients in both groups received the usual treatment of IBS by a gastroenterologist. The control group did not receive any intervention, whereas the experimental group was trained in the self-care program...
