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...

BACKGROUND: It has been suggested that probiotics may improve gastrointestinal discomfort. Not all probiotics exhibit the same effects and consequently meta-analyses on probiotics should be confined to well-defined strains or strain combinations. The aim of this study was to evaluate the effectiveness of a probiotic fermented milk (PFM) that includes Bifidobacterium lactis (B. lactis) CNCM I-2494 and lactic acid bacteria on gastrointestinal discomfort in the general adult population. METHODS: Double-blind randomized controlled trials in the general adult population comparing PFM with a control dairy product for at least 4 weeks were searched from multiple literature databases (up to February 2015)...

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder which represents a major cost to healthcare services. IBS-D patients represent about one-third of the IBS population and are currently treated with antispasmodics, loperamide, bile acid sequestrants and antidepressants. Alosetron and rifaximin are also available in USA, ramosetron in Japan, Korea and Thailand and ondansetron as an off-label treatment. Areas covered: This article focuses on eluxadoline, a novel pharmacological agent that has recently been approved by both the FDA and EMA for treatment of patients with IBS-D...

The Rome IV Diagnostic Questionnaires were developed to screen for functional gastrointestinal disorders (FGIDs), serve as inclusion criteria in clinical trials, and support epidemiological surveys. Separate questionnaires were developed for adults, children/adolescents, and infants/toddlers. For the adult questionnaire, we first surveyed 1,162 adults without gastrointestinal disorders, and recommended the 90th percentile symptom frequency as the threshold for defining what is abnormal. Diagnostic questions were formulated and verified with clinical experts using a recursive process...

Centrally Mediated Abdominal Pain Syndrome (CAPS), formerly known as Functional Abdominal Pain Syndrome, can be distinguished from other functional GI disorders by its strong central component and relative independence from motility disturbances. CAPS is a result of central sensitization with disinhibition of pain signals rather than increased peripheral afferent excitability. A newly described condition, Narcotic Bowel Syndrome (NBS)/Opioid-Induced GI Hyperalgesia, is characterized by the paradoxical development of or increases in abdominal pain associated with continuous or increasing dosages of opioids...

Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder, which represents a major cost to healthcare services. Current pharmacological treatment includes fibre supplements, antispasmodics, laxatives, loperamide and antidepressants. This article reviews the novel pharmacological treatments already or recently approved for patients with IBS-C (lubiprostone, linaclotide) and IBS-D (alosetron, ramosetron, rifaximin, eluxadoline). Furthermore, results for drugs in development (plecanatide, ibudutant and ebastine) or used in chronic constipation or for other indications, with potential application in IBS (prucalopride, elobixibat, mesalazine, ondansetron and colesevelam) are also reviewed...

Cronkhite-Canada syndrome (CCS) is a rare nongenetic polyposis syndrome first reported by Cronkhite and Canada in 1955. Up to the present time, the literature consists of ∼400 cases of CCS with the majority being reported from Japan although 49 cases have been described in China.CCS is characterized by diffuse polyposis of the digestive tract in association with ectodermal changes, such as onychomadesis, alopecia, and cutaneous hyperpigmentation. The principal symptoms of CCS are diarrhea, weight loss, abdominal pain, and other gastrointestinal complications, such as protein-losing enteropathy and malnutrition...

OBJECTIVE: Faecal incontinence (FI) is a devastating condition which is well recognised in the elderly and those with certain conditions such as inflammatory bowel disease. However, there is surprisingly little information on its prevalence in irritable bowel syndrome (IBS), especially in relation to bowel habit subtype, and this study aimed to answer this question. DESIGN: 500 consecutive new and follow-up secondary care IBS outpatients (399 female, 101 male, age range 15-87, mean age 46) fulfilling Rome III criteria without any significant concomitant disease were studied...

The classic symptoms of irritable bowel syndrome (IBS) are abdominal pain, bloating and some form of bowel dysfunction. The pain is typically colicky in nature and can occur at any site although most commonly it is on the left side. The abdomen feels flat in the morning and then gradually becomes more bloated as the day progresses reaching a peak by late afternoon or evening. It then subsides again over night. Traditionally IBS is divided into diarrhoea, constipation or alternating subtypes. IBS patients frequently complain of one or more non-colonic symptoms, these include constant lethargy, low backache, nausea, bladder symptoms suggestive of an irritable bladder, chest pain and dyspareunia in women...

BACKGROUND: Self-hypnosis is becoming increasingly popular as a means of labour pain management. Previous studies have produced mixed results. There are very few data on women's views and experiences of using hypnosis in this context. As part of a randomized controlled trial of self-hypnosis for intra-partum pain relief (the SHIP Trial) we conducted qualitative interviews with women randomized to the intervention arm to explore their views and experiences of using self-hypnosis during labour and birth...

The aim of the present study was to investigate the effect of Bifidobacterium animalis subsp. lactis, BB-12®, on two primary end points - defecation frequency and gastrointestinal (GI) well-being - in healthy adults with low defecation frequency and abdominal discomfort. A total of 1248 subjects were included in a randomised, double-blind, placebo-controlled trial. After a 2-week run-in period, subjects were randomised to 1 or 10 billion colony-forming units/d of the probiotic strain BB-12® or a matching placebo capsule once daily for 4 weeks...

Irritable bowel syndrome (IBS) is notoriously difficult to treat and this situation is unlikely to change until the pathophysiology is better understood. There is no doubt that IBS is a multifactorial condition but it is likely that the relative contribution of the various factors involved varies from patient to patient. Consequently, in some individuals one mechanism may have such a strong effect that its elimination may lead to a substantial improvement in symptoms. This paper describes a patient with severe asthma and IBS where the administration of an anti-Immunoglobulin E (IgE) monoclonal antibody not only improved her asthma but also resulted in an almost complete resolution of her IBS symptoms...

Visceral pain is a particularly difficult symptom to manage in patients with irritable bowel syndrome (IBS). Our aim was to examine whether noninvasive neurostimulation applied to the motor cortex or lumbosacral region can modulate human visceral sensation. Sixteen healthy adult volunteers and 10 patients with IBS were evaluated. Single-pulse lumbosacral magnetic stimulation (LSMS) or transcranial magnetic stimulation (TMS) was used to assess spinal root and cortical excitability as well as the effect of neurostimulation on anorectal sensation and pain, which were provoked by a local electrical stimulus...

INTRODUCTION: Immune activation has been reported in the mucosa of IBS patients with diarrhoea (IBS-D), and some small studies have suggested that mesalazine may reduce symptoms. We performed a double-blind, randomised placebo-controlled trial of 2 g mesalazine twice daily versus placebo for 3 months in patients with Rome III criteria IBS-D. Primary outcome was daily average stool frequency during weeks 11-12; secondary outcomes were abdominal pain, stool consistency, urgency and satisfactory relief of IBS symptoms...

BACKGROUND: The diagnostic processes for chronic abdominal conditions are challenging. Despite their tendency for diagnostic tests in patients with irritable bowel syndrome (IBS) symptoms, clinicians are encouraged to make a positive diagnosis based on symptom criteria without alarm signs. We explored how European physicians diagnose and manage patients suffering from IBS. METHODS: We conducted a vignette-based survey to evaluate the diagnostic approaches in four standardized patients with IBS with constipation (IBS-C), IBS with diarrhea (IBS-D), inflammatory bowel disease (IBD) and chronic constipation (CC)...
