This special article reports on two crucial issues discussed during a meeting. The first was the updated management of Helicobacter pylori infection. This was approached taking into account the recent European Guidelines, with a focus on novelties in treatment. In particular, considering the increasing H. pylori antibiotic resistance to clarithromycin, in countries with a high clarithromycin resistance rate the bismuth-containing quadruple therapies should be preferred. The new formulation, with bismuth, metronidazole, and tetracycline contained in a single capsule (three-in-one), has shown exciting results both in naive and in non-responder patients...

BACKGROUND AND AIM: Linaclotide is a guanylate cyclase-C agonist approved in multiple countries to treat irritable bowel syndrome with constipation (IBS-C). China has unmet need for well-tolerated therapy that is effective in treating both bowel and abdominal symptoms of IBS-C. This trial evaluated linaclotide's efficacy and safety in IBS-C patients in China and other regions. METHODS: This Phase 3, double-blind trial randomized IBS-C patients to once-daily oral 290-μg linaclotide or placebo at centers in China, North America, and Oceania...

BACKGROUND: Ramosetron is a potent and selective serotonin type 3 receptor antagonist. This meta-analysis aimed to analyze the efficacy and safety of ramosetron for irritable bowel syndrome with diarrhea (IBS-D). METHODS: Pubmed, MEDLINE, EMBASE and the Cochrane Library were searched for randomized controlled trials investigating the efficacy and safety of ramosetron for IBS-D. Risk of bias was assessed as described in the Cochrane handbook. A random effects model was used to calculate the effects of ramosetron vs placebo on symptomatic improvements, including relief of overall IBS symptoms, relief of abdominal discomfort/pain, improvement in abnormal bowel habits, and improvement in stool consistency, expressed as pooled relative risks (RRs) with 95% confidence interval (CI)...

BACKGROUND: The Rome III diagnostic criteria had been used to diagnose functional gastrointestinal disorders (FGIDs) world wide, and functional bowel disorders (FBDs) including irritable bowel syndrome (IBS) have recently attracted the attention of Japanese physicians. However, there have been few reports on the prevalence of FBDs diagnosed by the Rome III diagnostic criteria. AIMS: The aim of this study was to determine the prevalence of FBDs diagnosed according to the diagnostic criteria of Rome III in Japan...

Irritable bowel syndrome (IBS) is a chronic, recurrent bowel disorder with an unknown etiology, which is most likely multifactorial. Increased mucosal permeability, visceral hypersensitivity and activation status of intestinal mucosal immune cells cause changes in gastrointestinal (GI) motility, secretion and sensation observed in the course of IBS. Permanent, cumbersome symptoms, such as diarrhea, constipation and abdominal pain greatly lower quality of life of IBS patients. On this basis, according to the Rome IV criteria, different forms of IBS can be distinguished...

The Rome IIII( criteria were released in May 2016. Based on the development of brain-intestinal axis theory, intestinal microecology, pharmacogenomics and social psychology, the Rome IIII( criteria revise the definition, diagnostic criteria, clinical evaluation process, and treatments of functional constipation (FC). The revisions are as follows: (1) Definition: FC and constipation-predominant irritable bowel syndrome are considered to be on a continuum rather than as independent entities. (2) Diagnostic criteria: the Bristol stool scale type 1, type 2 and spontaneous bowel movements are added in the diagnostic criteria, respectively, refining the criteria for stool consistency and frequency...

PURPOSE OF REVIEW: The aim of this review is to summarize some of the key dietary interventions recommended for common gastrointestinal disorders and to discuss recent evidence regarding their nutritional implications. RECENT FINDINGS: The gluten-free diet has been shown to negatively influence overall diet quality. The gluten-free diet is essential in celiac disease, although it is increasingly used for other perceived health benefits for which an analysis of perceived benefit should be weighed against any nutritional risks...

BACKGROUND: Clinical testing to determine a suitable dose of linaclotide for Japanese patients with irritable bowel syndrome with constipation (IBS-C) was needed. METHODS: This was a randomized, double-blind, placebo-controlled, dose-finding trial. Japanese patients with IBS-C diagnosed using Rome III criteria (n = 559, men/women: 49/510) were randomly assigned to 1 of 4 linaclotide doses (0.0625, 0.125, 0.25, or 0.5 mg) or placebo for the 12-week treatment period...

BACKGROUND: Ingestion of radiopaque markers (ROM) is frequently used to determine colonic transit in chronic constipation. Although ≥20% of retained markers at 5 days defines slow-transit constipation, some clinicians use the number of retained markers to determine disease severity. METHODS: We assembled a cross-sectional cohort of patients presenting for evaluation of chronic constipation who underwent transit testing by ROM and completed validated symptom severity and quality-of-life (QOL) measures...

Abdominal pain is one of the key symptoms of irritable bowel syndrome (IBS). Studies have indicated an increase in the incidence of IBS in Asia. However, yet the pathophysiology of this disease remains unknown. Women are more likely to develop the condition than men, especially the constipation-predominant type. Essential fatty acid (EFA) malnutrition is one of several theories discussing the mechanism of IBS.The authors hypothesized that significant EFA deficiency may cause abdominal pain in patients with IBS...

Apoorva Krishna Chandar
Irritable bowel syndrome (IBS) is a complex functional gastrointestinal disorder that is exceedingly common in clinical practice. IBS with predominant constipation (IBS-C) is a subtype of IBS that accounts for more than a third of the IBS diagnosed. Diagnosis of IBS requires a careful personalized approach, a comprehensive clinical history, limited but relevant investigations, and continued follow-up. Major IBS societies and guidelines recommend offering a positive diagnosis of IBS based on presenting symptomatology...

REVIEW

Purinergic receptors are implicated in the pathogenesis of gastrointestinal disorders and are being explored as potential therapeutic targets. Gut inflammation releases ATP that acts on neuronal, glial, epithelial and immune cells. Purinergic signalling in glia and neurons is implicated in enteric neuropathies. Inflammation activates glia to increase ATP release and alter purinergic signalling. ATP release causes neuron death and gut motor dysfunction in colitis via a P2X7-dependent neural-glial pathway and a glial purinergic-connexin-43 pathway...

Anam Omer, Eamonn M M Quigley
Chronic constipation (CC) is a highly prevalent and often under-appreciated gastrointestinal disorder associated with significant impairment in quality of life. Symptoms of constipation are typically present for a number of years prior to a patient seeking help. Lifestyle modifications followed by, or coupled with, over-the-counter laxatives represent the initial treatment option; however, relief for many is limited and dissatisfaction rates for these approaches remain high. Over recent years, therefore, considerable effort has been exerted on the development of novel pharmacological approaches...

Chronic abdominal and pelvic pain are common, debilitating clinical conditions experienced by millions of patients around the globe. The origin of such pain commonly arises from the intestine and bladder, which share common primary roles; the collection, storage and expulsion of waste. These visceral organs are located in close proximity to one another, and also share common innervation from spinal afferent pathways. Chronic abdominal pain, constipation or diarrhoea are primary symptoms for patients with Irritable Bowel Syndrome (IBS) or Inflammatory Bowel Disease (IBD)...

Fecal microbiota transplantation (FMT), also known as fecal bacteriotherapy or fecal infusion, consists of injection of a liquid filtrate of feces from a healthy donor into the gastrointestinal tract of a recipient individual. FMT has been proposed as a therapeutic approach for functional diseases of the gastrointestinal tract by reestablishment of a wide diversity of intestinal flora. Clostridium difficile infection (CDI) treatment guideline from American Gastroenterology Association (AGA) recommends that FMT can be used as the treatment protocols of relapse CDI...
