Irritable bowel syndrome (IBS) was previously considered as a psychosomatic disorder. But recent studies indicate that inflammation plays a significant role. The present study was undertaken to evaluate role of pro-inflammatory (IL 2, IL 6 and IL 8) and anti-inflammatory (IL 10) cytokines in clinically diagnosed patients of IBS. 51 patients and 29 controls were included in this study. On the basis of history of gastrointestinal infection, patients were divided into Post Infectious (PIIBS) and Non Post Infectious (NPIIBS) groups...

Irritable bowel syndrome (IBS), which is characterized by recurrent abdominal pain and disordered bowel habits, is one of the most common functional bowel disorders. IBS is a substantial burden on both patient health-related quality of life and health care costs. Several pathophysiologic mechanisms have been postulated for the occurrence of IBS, including altered gastrointestinal motility, visceral hypersensitivity, changes in gut permeability, immune activation, gut-brain dysregulation, autonomic nervous system dysfunction, and changes in the gut microbiota...

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal (GI) disorder that can significantly erode the quality of life (QoL) of sufferers and places a major cost burden on healthcare services. This paper reviews the literature on the impact of IBS on healthcare services and society, including a recent report on the subject, in order to formulate a plan for the future. A completely different model of care for these patients is recommended based on this review and the experience of the two authors who have been treating patients with functional GI disorders for 20 and 35 years, respectively...

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder characterized by abdominal pain associated with defecation with altered stool frequency or stool form. The global prevalence of IBS ranges from 10% to 15% and total healthcare cost attributable to IBS is significant. Among individuals with IBS, the condition has dramatic effects on health-related quality of life, work and school productivity, and activities of daily living. It may be diagnosed with confidence, based on symptom-based diagnostic criteria, exclusion of alarm features and directed diagnostic testing...

BACKGROUND: Diarrhea-predominant irritable bowel syndrome (IBS-D) impairs patient quality of life (QOL). Rifaximin is an oral, nonsystemic antibiotic indicated for IBS-D. The objective of this secondary analysis was to evaluate rifaximin retreatment on IBS-related QOL in patients with IBS-D. METHODS: Patients received open-label rifaximin 550 mg three times daily for 2 weeks. Clinical responders [simultaneously meeting weekly response criteria for abdominal pain (⩾30% improvement from baseline in mean weekly pain score) and stool consistency (⩾50% decrease from baseline in number of days/week with Bristol Stool Scale (BSS) type 6 or 7 stools) during ⩾2 of first 4 weeks posttreatment] who relapsed during an up to 18-week treatment-free observation phase were randomly assigned to receive two 2-week courses of double-blind rifaximin or placebo, separated by 10 weeks...

BACKGROUND/AIMS: Irritable bowel syndrome (IBS), defined as recurrent abdominal pain and changes in bowel habits, seriously affects quality of life and ability to work. Ghrelin is a brain-gut hormone, which has been reported to show antinociceptive effects in peripheral pain. We investigated the effect of ghrelin on visceral hypersensitivity and pain in a rat model of IBS. METHODS: Maternal deprivation (MD) was used to provide a stress-induced model of IBS in Wistar rats...

James F White
This article outlines the proposed 'syntrophic imbalance hypothesis' for etiology of bacterial endoparasitism diseases. This hypothesis involves microbes (archaea and bacteria) that exist in human body biofilms in syntrophic associations, where bacteria ferment nutrients to produce short chain fatty acids (SCFAs) that are used by methanogenic archaeons to produce methane. Overgrowth of archaea on human tissues (e.g., in association with intestines, teeth or lungs) results in excessive removal of SCFAs from the biofilms and this triggers bacteria in the free-living biofilm state to convert to the endoparasitic state and become intracellular in host cells where they incite inflammation and disease...

OBJECTIVE: Induction of negative affective states can enhance bodily symptoms in high habitual symptom reporters among healthy persons, and in patients with irritable bowel syndrome. The aim of this study was to replicate this effect in patients with fibromyalgia and chronic fatigue syndrome and to investigate the role of moderators, focusing on alexithymia, negative affectivity (NA) and absorption. METHODS: Patients with fibromyalgia and/or chronic fatigue syndrome (N=81) and healthy controls (HC, N=41) viewed series of neutral, positive and negative affective pictures...

Historically, the epidemiology of gastrointestinal diseases in Asia was different from that in Western countries. Early studies suggested a low prevalence of irritable bowel syndrome (IBS) in Asia. As the diagnosis of IBS is symptom-based, and as symptom perception, expression and interpretation, are influenced by sociocultural perspectives including language, the presentation of IBS is expected to vary in different communities. Furthermore, the pathogenesis is multifactorial with psychosocial (stress, illness, behavior, diet) and biological (infection, gut microbiota, immune activation) variables interacting, and so we can anticipate that the development of IBS will vary in different environments...

BACKGROUND: Irritable bowel syndrome is classified as a functional gastrointestinal disorder with the primary symptom of abdominal pain in conjunction with bloating and bowel movement disorder. It affects up to 15% of the world's population. Among its subtypes, the most common is diarrhoea predominant. However, the current treatment options for diarrhoea-predominant irritable bowel syndrome have had not very promising results; most, such as antispasmodics, only provide partial symptomatic relief...

Bile acids not only play a cardinal role in the digestion and absorption of fat and fat-soluble vitamins, but also significantly affect gastrointestinal motor, sensory and secretory functions, intestinal barrier permeability and the regulation of the inflammatory response. The results of recent studies have revealed complex interactions between bile acids and the gut microbiota. In addition, bile acids also play a role of signaling molecules regulating the activity of lipid and glucose metabolic pathways, as well as a role of ligands for transcription factors...

INTRODUCTION: Gastrointestinal (GI) distress in endurance athletes is prevalent and detrimental to performance. Adverse GI symptomatology can be analogous with irritable bowel syndrome, where fermentable oligosaccharide, disaccharide, monosaccharide and polyols (FODMAP) reduction has demonstrated efficacy. This study investigated the effects of low FODMAP (LFOD) diet on GI distress parameters in runners with a history of non-clinical exercise-associated GI symptoms. METHODS: Eleven recreationally competitive runners (5 males, 6 females; 5km personal best 23:00±4:02 min:sec) participated in the study...

BACKGROUND AND PURPOSE: The majority of Parkinson's disease (PD) patients suffer from gastrointestinal symptoms of which constipation is considered the most prominent. Recently, in addition to constipation, a diagnosis of irritable bowel syndrome (IBS) was also found to be associated with increased PD risk. Gut microbiota alterations have been reported in IBS and recently also in PD. IBS-like bowel symptoms in PD and their possible connection to other non-motor symptoms and faecal microbiota were assessed...

PURPOSE OF REVIEW: The goal of this review is to review the current status of prokinetics and to place it in historical context. Impaired motility and thus propulsion have long been thought to play important roles in the pathogenesis of a number of gastrointestinal disorders including gastroesophageal reflux disease (GERD), gastroparesis, chronic idiopathic pseudo-obstruction, and constipation. Historically, disordered motility was also thought to contribute to a number of functional gastrointestinal disorders such as functional dyspepsia (FD) and irritable bowel syndrome (IBS)...

Psychological comorbidity is highly present in irritable bowel syndrome (IBS). Recent research points to a role of intestinal microbiota in visceral hypersensitivity, anxiety, and depression. Increased disease reactivity to psychological stress has been described too. A few clinical studies have attempted to identify features of dysbiosis in IBS. While animal studies revealed strong associations between stress and gut microbiota, studies in humans are rare. This review covers the most important studies on intestinal microbial correlates of psychological and clinical features in IBS, including stress, anxiety, and depression...

Exercise can have significant effects on gastrointestinal diseases. Regular, moderate exercise can impart beneficial effects for the intestinal microbiome, irritable bowel syndrome symptoms, and inflammatory bowel disease. High-intensity training or prolonged endurance training, on the other hand, can have negative effects on these same entities. Female athletes report a higher prevalence of irritable bowel syndrome and celiac disease, and furthermore, have gastrointestinal symptoms modulated by the menstrual cycle...
