Disruption of autophagy by increased #5-HT alters gut microbiota and enhances susceptibility to experimental colitis and #Crohn’s disease

Autophagy, an essential intracellular recycling process, is linked to the pathogenesis of various diseases including Crohn’s disease (CD). Factors that lead to the development of impaired autophagy during intestinal inflammation remain largely unexplored. Here, we report the impact of the interaction between serotonin [5-hydroxytryptamine;(5-HT)] and autophagy in colitis in mouse and human studies. In mice,… Continue reading Disruption of autophagy by increased #5-HT alters gut microbiota and enhances susceptibility to experimental colitis and #Crohn’s disease

Serum #procalcitonin levels associate with #Clostridioides difficile infection in patients with #inflammatory bowel disease

Clostridioides difficile infection (CDI) is a major cause of morbidity among patients with inflammatory bowel disease (IBD). Diagnostic biomarkers for early detection of CDI are needed in clinical practice. The relationship between serum procalcitonin and CDI in IBD patients has not been investigated so far. Therefore, we aimed to evaluate the usefulness of measuring serum… Continue reading Serum #procalcitonin levels associate with #Clostridioides difficile infection in patients with #inflammatory bowel disease

Identification of a choroid plexus vascular barrier closing during #intestinal inflammation

Locking down access to the brainInflammatory bowel disease is best known for intestinal symptoms but can also cause a variety of extraintestinal manifestations in other organs. It can also be associated with cognitive and psychiatric effects, including anxiety and depression. Using mouse models of intestinal inflammation, Carloni et al. uncovered a potential pathogenic link between… Continue reading Identification of a choroid plexus vascular barrier closing during #intestinal inflammation

Association of ultra-processed #food intake with risk of #inflammatory bowel disease: prospective cohort study

To evaluate the relation between intake of ultra-processed food and risk of inflammatory bowel disease (IBD). Design Prospective cohort study. Setting 21 low, middle, and high income countries across seven geographical regions (Europe and North America, South America, Africa, Middle East, south Asia, South East Asia, and China). Participants 116 087 adults aged 35-70 years with… Continue reading Association of ultra-processed #food intake with risk of #inflammatory bowel disease: prospective cohort study

Self-tunable engineered yeast #probiotics for the treatment of #inflammatory bowel disease

Inflammatory bowel disease (IBD) is a complex chronic inflammatory disorder of the gastrointestinal tract. Extracellular adenosine triphosphate (eATP) produced by the commensal microbiota and host cells activates purinergic signaling, promoting intestinal inflammation and pathology. Based on the role of eATP in intestinal inflammation, we developed yeast-based engineered probiotics that express a human P2Y2 purinergic receptor… Continue reading Self-tunable engineered yeast #probiotics for the treatment of #inflammatory bowel disease

Adherent-invasive E. coli metabolism of propanediol in #Crohn’s disease regulates phagocytes to drive intestinal #inflammation

Adherent-invasive E. coli (AIEC) are enriched in the intestinal microbiota of patients with Crohn’s disease (CD) and promote intestinal inflammation. Yet, how AIEC metabolism of nutrients impacts intestinal homeostasis is poorly defined. Here, we show that AIEC encoding the large subunit of propanediol dehydratase (PduC), which facilitates the utilization of fucose fermentation product 1,2-propanediol, are… Continue reading Adherent-invasive E. coli metabolism of propanediol in #Crohn’s disease regulates phagocytes to drive intestinal #inflammation

Are Patients With Inflammatory Bowel Disease at an Increased Risk of Developing #SARS-CoV-2 than Patients Without Inflammatory #Bowel Disease? Results From a Nationwide Veterans’ Affairs Cohort Study

The clinic course of SARS-CoV-2 among patients with inflammatory bowel disease (IBD) has been extensively studied. However, there is a paucity of data on whether patients with IBD have an increased risk of developing SARS-CoV-2 with compared with patients without IBD. METHODS: We conducted a nationwide retrospective cohort study in the US Veterans’ Affairs healthcare… Continue reading Are Patients With Inflammatory Bowel Disease at an Increased Risk of Developing #SARS-CoV-2 than Patients Without Inflammatory #Bowel Disease? Results From a Nationwide Veterans’ Affairs Cohort Study

Elevated ectodomain of type 23 #collagen is a novel biomarker of the intestinal epithelium to monitor disease activity in #ulcerative colitis and #Crohn’s disease

Impaired intestinal epithelial barrier is highly affected in inflammatory bowel disease. Transmembrane collagens connecting the epithelial cells to the extracellular matrix have an important role in epithelial cell homeostasis. Thus, we sought to determine whether the transmembrane type 23 collagen could serve as a surrogate marker for disease activity in patients with Crohn’s disease and… Continue reading Elevated ectodomain of type 23 #collagen is a novel biomarker of the intestinal epithelium to monitor disease activity in #ulcerative colitis and #Crohn’s disease

The influence of #proton pump inhibitor therapy on the outcome of #infliximab therapy in inflammatory bowel disease: a patient-level meta-analysis of randomised controlled studies

In treating patients with inflammatory bowel disease (IBD), how concomitant medications influence the response to infliximab is largely unexplored. We aim to evaluate whether proton pump inhibitors (PPIs) affect the response to infliximab therapy in patients with IBD.. Among the five randomised controlled studies, there were 889 and 147 patients on infliximab with and without… Continue reading The influence of #proton pump inhibitor therapy on the outcome of #infliximab therapy in inflammatory bowel disease: a patient-level meta-analysis of randomised controlled studies
