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?

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

Heterogeneity and clonal relationships of adaptive immune cells in #ulcerative colitis revealed by single-cell analyses

Inflammatory bowel disease (IBD) encompasses a spectrum of gastrointestinal disorders driven by dysregulated immune responses against gut microbiota. We integrated single-cell RNA and antigen receptor sequencing to elucidate key components, cellular states, and clonal relationships of the peripheral and gastrointestinal mucosal immune systems in health and ulcerative colitis (UC). UC was associated with an increase… Continue reading Heterogeneity and clonal relationships of adaptive immune cells in #ulcerative colitis revealed by single-cell analyses

Inflammatory bowel disease is associated with higher dementia risk: a nationwide longitudinal study

Increasing evidence supports reciprocal communication between the enteric and the central nervous system in disease, termed the ‘gut–brain axis’. Recent findings suggest a connection between IBD and development of Parkinson’s disease. The role of IBD in dementia, another insidious neurodegenerative disorder, has not been explored.. ..Overall incidence of dementia among patients with IBD was significantly… Continue reading Inflammatory bowel disease is associated with higher dementia risk: a nationwide longitudinal study

Outcomes of COVID-19 in 79 patients with #IBD in Italy: an IG-IBD study

COVID-19 has rapidly become a major health emergency worldwide. Patients with IBD are at increased risk of infection, especially when they have active disease and are taking immunosuppressive therapy. The characteristics and outcomes of COVID-19 in patients with IBD remain unclear.. ..Between 11 and 29 March 2020, 79 patients with IBD with COVID-19 were enrolled… Continue reading Outcomes of COVID-19 in 79 patients with #IBD in Italy: an IG-IBD study

IFN-γ drives inflammatory bowel disease pathogenesis through VE-cadherin–directed #vascular barrier disruption

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder with rising incidence. Diseased tissues are heavily vascularized ..Specifically, we show that inhibition of the IFN-γ response in vessels by endothelial-specific knockout of IFN-γ receptor 2 ameliorates experimentally induced colitis in mice. IFN-γ acts pathogenic by causing a breakdown of the vascular barrier through disruption of… Continue reading IFN-γ drives inflammatory bowel disease pathogenesis through VE-cadherin–directed #vascular barrier disruption
