Cancer Risk in IBD Patients Treated with JAK Inhibitors: Reassuring Evidence from Trials and Real-World Data.

The advent of Janus kinase (JAK) inhibitors, including tofacitinib, filgotinib, and upadacitinib, has significantly widened the therapeutic options for patients with inflammatory bowel disease (IBD). These agents offer the advantage of oral administration and have demonstrated efficacy in inducing and maintaining remission. However, concerns regarding their safety have emerged, particularly concerning cardiovascular and infectious complications, which appear more pronounced in patients with pre-existing risk factors such as older age, smoking, or comorbidities.

Novel Insights into the Pathogenesis of Inflammatory Bowel Diseases.

Inflammatory bowel diseases (IBDs), encompassing Crohn's disease and ulcerative colitis, are complex chronic disorders characterized by an intricate interplay between genetic predisposition, immune dysregulation, gut microbiota alterations, and environmental exposures. This review aims to synthesize recent advances in IBD pathogenesis, exploring key mechanisms and potential avenues for prevention and personalized therapy. A comprehensive literature search was conducted across major bibliographic databases, selecting the most recent and impactful studies on IBD pathogenesis.
