Introduction: Although there are well-defined guidelines for the management of mild-to-moderate ulcerative colitis (UC), there are still unmet needs. For this reason, we conducted an international expert consensus to standardize the management of patients with mild-to-moderate UC and provide practical guidance to clinicians.

Areas Covered: Based on Delphi methodology, 15 statements were approved after two rounds of voting, addressing several aspects of disease management from sequencing to treatment duration, from monitoring to optimization techniques and safety profile.

Imbalanced dietary intake is associated with the development of inflammatory bowel diseases (IBDs) and is often observed during the active phases of Crohn's disease (CD) and ulcerative colitis (UC). Cumulative data also suggest the potential for dietary manipulation in avoiding IBD relapse. However, there is a paucity of dietary data from patients in clinical remission to guide such an approach.

Inflammatory bowel diseases (IBD) are chronic conditions arising from an intricate interplay of genetics and environmental factors, and are associated with gut dysbiosis, inflammation, and gut permeability. In this study, we investigated whether the inflammatory potential of the diet is associated with the gut microbiota profile, inflammation, and permeability in forty patients with IBD in clinical remission. The dietary inflammatory index (DII) score was used to assess the inflammatory potential of the diet.

As the patents for biologic originator drugs expire, biosimilars are emerging as cost-effective alternatives within healthcare systems. Addressing various challenges in the clinical management of inflammatory bowel disease (IBD) remains crucial. To shed light on physicians' current knowledge, beliefs, practical approaches, and concerns related to biosimilar adoption-whether initiating a biosimilar, transitioning from an originator to a biosimilar, or switching between biosimilars (including multiple switches and reverse switching)-a global survey was conducted.

Perianal fistulizing Crohn's disease (PFCD) is a disabling complication of Crohn's disease (CD) that can significantly impact on patients' quality of life (QoL) and often requires multidisciplinary care. Clinical trials assessing the efficacy of medical and surgical interventions for fistulas usually evaluate outcomes such as closure of fistula tracts or radiologic healing. However, these traditional outcome assessments fail in capturing the impact of the disease from patients' perspectives.

Despite significant improvements in the management of ulcerative colitis (UC) in parallel with the evolution of therapeutic targets and novel biologics and small molecules, a subset of medically refractory patients still requires colectomy. Recent population-based studies demonstrate a trend toward a decrease in the rates of surgery for UC patients in the biological era, although the potential of disease modification with these agents is still debated. As the concept of irreversible bowel damage is underexplored in UC, refractory patients can be exposed to multiple treatments losing optimal timing for surgery and further developing complications such as dysplasia/cancer, dysmotility, microcolon, and other functional abnormalities.

Background: Inflammatory bowel diseases (IBD), comprising Crohn's disease and ulcerative colitis, are chronic inflammatory diseases of the gastrointestinal tract that often have their onset among adolescents and young adults (AYA). IBD are characterized by episodes of active disease interspersed with periods of remission, and its activity is inversely correlated with health-related quality of life (HRQL).

Objective: This study aimed to determine whether AYA in remission or with low IBD activity would exhibit HRQL similar to that of age-matched healthy individuals, and whether demographic and disease factors could affect HRQL using a 'patient-reported outcome' instrument.

Despite significant development in the pharmacological treatment of inflammatory bowel diseases (IBD) along with the evolution of therapeutic targets and treatment strategies, a significant subset of patients still requires surgery during the course of the disease. As IBD patients are frequently exposed to biologics at the time of abdominal and perianal surgery, it is crucial to identify any potential impact of biological agents in the perioperative period. Even though detectable serum concentrations of biologics do not seem to increase postoperative complications after abdominal procedures in IBD, there is increasing evidence on the role of therapeutic drug monitoring (TDM) in the perioperative setting.
