Gut microbial dysbiosis associated to diarrheic irritable bowel syndrome can be efficiently simulated in the Mucosal ARtificial COLon (M-ARCOL).

Irritable bowel syndrome (IBS) is a common chronic gastrointestinal disorder, with diarrhea-predominant IBS (IBS-D) as the most frequent subtype. The implication of gut microbiota in the disease's etiology is not fully understood. gut systems can offer a great alternative to assays in preclinical studies, but no model reproducing IBS-related dysbiotic microbiota has been developed.

Development and Validation of a Score to Assess Transmural Healing and Response in Patients With Crohn's Disease.

Background & Aims: Because transmural healing (TH) could be the best therapeutic target in Crohn's disease (CD), we aimed to build and validate a score to assess TH and transmural response (TR), and to confirm their association with favorable CD outcomes.

Methods: DEVISE-CD project encompassed 2 retrospective cohorts (274 and 224 patients with CD for development and validation phase, retrospectively) and 1 multicenter prospective validation cohort (N = 46 patients). A step-by-step process was used to build the modified Clermont score (C-score).

Case Series of 11 Families (47 Carriers) Including Incidental Findings, Signet Ring Cell Colon Cancer and Review of the Literature.

Germline pathogenic variants in E-cadherin () confer high risk of developing lobular breast cancer and diffuse gastric cancer (DGC). The cumulative risk of DGC in carriers has been recently reassessed (from 40-83% by age 80 to 25-42%) and varies according to the presence and number of gastric cancers in the family. As there is no accurate estimate of the risk of gastric cancer in families without DGC, the International Gastric Cancer Linkage Consortium recommendation is not straightforward: prophylactic gastrectomy or endoscopic surveillance should be proposed for these families.

LA806 Supplementation in Patients with Irritable Bowel Syndrome: A Multicenter Study.

The potential benefits of Lactobacillus gasseri LA806 in IBS were previously identified in a comprehensive preclinical research program. The purpose of this multicenter study was to explore in real-life conditions changes in IBS symptoms and quality of life in patients receiving a 4-week supplementation with L. gasseri LA806.

The use of Faecal Microbiota Transplantation (FMT) in Europe: A Europe-wide survey.

Background: Faecal microbiota transplantation (FMT) is an emerging treatment modality, but its current clinical use and organisation are unknown. We aimed to describe the clinical use, conduct, and potential for FMT in Europe.

Methods: We invited all hospital-based FMT centres within the European Council member states to answer a web-based questionnaire covering their clinical activities, organisation, and regulation of FMT in 2019.

Prokaryotic and Eukaryotic Fecal Microbiota in Irritable Bowel Syndrome Patients and Healthy Individuals Colonized With .

is the most frequently isolated protozoan from human stool. Its role in human health is still debated, and a high prevalence was reported in irritable bowel syndrome (IBS) subjects, suggesting a potential link with microbiota. In the present study, we aimed to investigate prokaryotic and eukaryotic microbiota in both IBS-C (constipated) and healthy individuals.

Early Transmural Response Assessed Using Magnetic Resonance Imaging Could Predict Sustained Clinical Remission and Prevent Bowel Damage in Patients with Crohn's Disease Treated with Anti-Tumour Necrosis Factor Therapy.

Background: Magnetic resonance imaging [MRI] is a promising tool to evaluate therapeutic efficacy in ileocolonic Crohn's disease [CD].

Aims: We aimed to assess the feasibility of early MRI evaluation (week 12 [W12]) to predict corticosteroid-free remission [CFREM] at W52 and prevent long-term bowel damage.

Methods: All patients with active CD needing anti-tumour necrosis factor [anti-TNF] therapy were consecutively enrolled in this multicentre prospective study.

[Intestinal microbiota and allogeneic stem cell transplantation].

Allogeneic hematopoïetic stem cell transplantation is one of the most efficient curative treatment for acute leukemia. But it is also a heavy process with an important risk of complications, particularly infection and graft versus host disease. Increasing data in literature show that an alteration of the intestinal microbiota of allogeneic stem cell recipients is associated with these complications.

Assessment of the effectiveness and safety of ethosuximide in the treatment of abdominal pain related to irritable bowel syndrome - IBSET: protocol of a randomised, parallel, controlled, double-blind and multicentre trial.

Introduction: Irritable bowel syndrome (IBS) is characterised by the association of abdominal chronic pain with bowel habit disorders in the absence of identifiable organic disease. This is the first reason for consultation in gastroenterology, with an estimated prevalence of 10%-15% in industrialised countries. Although this is a benign gastrointestinal disease, its chronicity profoundly impacts the patient's quality of life and causes considerable health spending.

Adenoma detection with blue-water infusion colonoscopy: a randomized trial.

Unlabelled:  Colonoscopy is currently the reference method to detect colorectal neoplasia, yet some adenomas remain undetected. The water infusion technique and dying with indigo carmine has shown interesting results for reducing this miss rate. The aim of this study was to compare the adenoma detection rate (adenoma and adenocarcinoma; ADR) and the mean number of adenomas per patient (MAP) for blue-water infusion colonoscopy (BWIC) versus standard colonoscopy.

Colonic overexpression of the T-type calcium channel Ca 3.2 in a mouse model of visceral hypersensitivity and in irritable bowel syndrome patients.

Background: Among the different mechanisms involved in irritable bowel syndrome (IBS) physiopathology, visceral hypersensitivity seems to play a key role. It involves sensitization of the colonic primary afferent fibers, especially through an overexpression of ion channels. The aims of this translational study were to investigate the colonic expression of Ca 3.

Temporary placement of a covered duodenal stent can avoid riskier anterograde biliary drainage when ERCP for obstructive jaundice fails due to duodenal invasion.

Background: Duodenal stenosis is one of the most common causes of failed ERCP for obstructive jaundice. Alternative approaches include anterograde biliary drainage, with higher morbidity. We report in this study the efficacy and safety of temporary placement of a covered duodenal self-expandable metal stent (cSEMS) in order to access the papilla and achieve secondary retrograde biliary drainage in patients with obstructive jaundice and failed ERCP due to concomitant duodenal stenosis.

Diffusion-weighted magnetic resonance enterocolonography in predicting remission after anti-TNF induction therapy in Crohn's disease.

Background: Diffusion-weighted magnetic resonance entero-colonography (DW-MREC) with no rectal distension and with no bowel cleansing is accurate to assess inflammatory activity in ileocolonic Crohn's disease (CD).

Aim: To study DW-MREC parameters as predictors of remission (CDAI < 150 and CRP < 5mg/L) after anti-TNF induction therapy.

Methods: Forty consecutive CD patients were prospectively and consecutively included.

Faecal microbiota transplantation in recurrent Clostridium difficile infection: Recommendations from the French Group of Faecal microbiota Transplantation.

Faecal microbiota transplantation is effective for treating recurrent forms of Clostridium difficile infection and its use in this indication is recommended in the most recent European and North American guidelines. In this context, faecal microbiota transplantation is beginning to be performed in France in clinical practice, while the rules governing this procedure have been defined in France only for clinical trials. To unify, secure, and evaluate practice in this field in France, the French Group of Faecal microbiota Transplantation (FGFT) was created in October 2014 with the support of the French National Society of Gastroenterology, the French Infectious Disease Society, and the National Academy of Pharmacy.

Blastocystis is associated with decrease of fecal microbiota protective bacteria: comparative analysis between patients with irritable bowel syndrome and control subjects.

Blastocystis is a protistan parasite living in the digestive tract of many animals, including humans. This highly prevalent intestinal parasite is suspected to be linked to Irritable Bowel Syndrome (IBS), a chronic functional bowel disorder. Here, we first compared the prevalence of Blastocystis among 56 IBS patients (40 IBS with constipation (IBS-C), 9 IBS with diarrhea (IBS-D), 4 mixed IBS (IBS-M) and 3 unsubtyped IBS (IBS-U) according to the Rome III criteria) and 56 control (i.

Pancreatic intubation facilitated by methylene blue injection decreases the risk for postpapillectomy acute pancreatitis.

Objectives: Endoscopic snare papillectomy (ESP) is a viable alternative to surgical treatment of ampullary adenomas and T1N0 stage ampullary carcinomas. The main drawback of this technique is the high risk of acute pancreatitis post procedure.The aim of this study was to assess the efficacy, safety, and long-term results of this procedure, and to determine whether routine pancreatic intubation facilitated by intraductal methylene blue (MB) injection reduces the risk for pancreatitis.

Diffusion-weighted magnetic resonance imaging in ileocolonic Crohn's disease: validation of quantitative index of activity.

Objectives: Magnetic resonance imaging (MRI) allows accurate assessment of Crohn's disease (CD), but requires gadolinium injection. Diffusion-weighted (DW)-MRI yields comparable performances in small bowel CD. We compared the accuracy of DW-MR enterocolonography (MREC) and the magnetic resonance index of activity (MaRIA), and performed an external validation of the Clermont score in assessing inflammation in CD.
