This Guideline is an official statement of the European Society Gastrointestinal Endoscopy (ESGE). It addresses diagnosis and management nonvariceal upper gastrointestinal hemorrhage (NVUGIH). <b>Main Recommendations</b> <b>MR1.</b> ESGE recommends immediate assessment hemodynamic status in patients who present with acute (UGIH), prompt intravascular volume replacement initially using crystalloid fluids if instability exists (strong recommendation, moderate quality evidence). <b>MR2.</b> a...

Significance Our findings demonstrate that metabolic supplementation of mucosal T cells, isolated from patients with active ulcerative colitis (UC), N -acetylglucosamine (GlcNAc) leads to the enhancement branched N-glycosylation on cell receptor, which was associated control activation and function. These results were validated in “glycoengineered” mouse models severe colitis. Overall, our open new avenues for a targeted-specific therapy inflammatory bowel disease (IBD). The therapeutic use...

Interstitial lung [ILD] disease and granulomatous [GLD] are rare respiratory disorders that have been associated with inflammatory bowel [IBD]. Clinical presentation is polymorphic aetiology unclear.This was an ECCO-CONFER project. Cases of concomitant ILD or GLD IBD, drug-induced ILD/GLD, were collected. The criteria for diagnosing based on definitions from the American Thoracic Society European Respiratory discretion reporting clinician.We identified 31 patients ILD. majority had...

Abstract Background The current standard of treatment in primary biliary cholangitis (PBC) is ursodeoxycholic acid (UDCA), although a considerable proportion patients show incomplete response resulting disease progression. Objective This study aimed to assess the prevalence UDCA and determine associated patients' characteristics. Methods Patients with PBC as main diagnosis were included from national multicentric patient registry—Liver.pt. Main endpoints according Barcelona, Paris I II...

There is a clinical need to identify biomarkers able select patients who are most likely develop aggressive/complicated disease, for early selection appropriate therapy. Changes in the glycosylation profile of intestinal lymphocytic infiltrate were previously demonstrated regulate T cell activity, being associated with disease severity ulcerative colitis [UC] patients. We interrogated whether this heterogeneous expression branched N-glycans inflammatory predicts therapy response course.The...

Direct-acting antivirals (DAA) have revolutionized hepatitis C treatment, with high sustained virological response (SVR) rates reported, even in historically difficult-to-treat groups. SVR is associated a decreased risk of hepatocellular carcinoma (HCC), need for transplantation, and overall liver-related mortality. Data from real-life cohorts on the medium- to long-term outcomes patients advanced liver disease DAA-induced are still missing.To report analyze cohort disease.In this...

Background & Aims: Endoscopic sphincterotomy (ES) with stone extraction is the standard treatment for choledocholithiasis.After retrieval, balloon-occluded cholangiography generally performed to confirm bile duct clearance but can miss residual stones particularly in patients small-sized stones, a large or pneumobilia.In addition, difficult common (CBD) requiring advanced endoscopic techniques retrieval are potential risk factor choledocholithiasis recurrence.Methods: We retrospective...

Persons with haemophilia (PWH) used to represent a population high prevalence of hepatitis C virus (HCV) infection due the use contaminated blood products. Although goals antiviral therapy are same as general population, long real-life follow-up data regarding their outcomes still scarce.
