Long-Term Effectiveness and Safety of Ustekinumab in Crohn's Disease: Results from a Large Real-Life Cohort Study.

Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist approved for the treatment of Crohn's disease (CD). Only limited real-life data on the long-term outcomes of CD patients treated with UST are available. This study assessed UST's long-term effectiveness and safety in a large population-based cohort of moderate to severe CD patients.

Switching rate from intravenous to subcutaneous vedolizumab in managing inflammatory bowel diseases is lower than expected.

Background: It is known that the subcutaneous (SC) route administration of biologic drugs has several potential benefits for patient and the healthcare system. Since few real-world data are available yet about the rate of transition from intravenous (IV) to SC Vedolizumab (VDZ) in the Italian population, we assessed this rate in a large cohort of inflammatory bowel disease (IBD) patients under remission receiving IV VDZ as standard of care in a real-world setting.

Methods: Searching who was asked to switch from IV VDZ To SC VDZ, and assessing the rate of acceptance.

International expert guidance for defining and monitoring small bowel strictures in Crohn's disease on intestinal ultrasound: a consensus statement.

Background: Diagnostic imaging using CT enterography, magnetic resonance enterography, and intestinal ultrasound are important tools in evaluating stricturing Crohn's disease. Definitions of strictures have been developed for CT enterography and magnetic resonance enterography. However, expert recommendations for definitions and treatment response of strictures on intestinal ultrasound are not available.

Ultrasound assessment of gastrointestinal luminal contents: a narrative review.

Gastro-intestinal ultrasound (GIUS) is a non-invasive and cost-effective tool, widely used as a first-line diagnostic method in patients presenting with abdominal complaints, especially in patients affected by inflammatory bowel disease (IBD), such as Crohn's disease and ulcerative colitis. In this setting, gastro-intestinal ultrasound has been especially used to evaluate the bowel wall features (thickening, stratification, vascularization) and complications related to IBD (fistulas, abscesses). Nevertheless, gastro-intestinal ultrasound can be also used to detect and evaluate the content of several segments of the gut.
