Special Issue Information

Dear Colleagues,

Inflammatory bowel disease (IBD) is a comprehensive medical term that represents a spectrum of chronic, idiopathic, and immunologically mediated digestive tract disorders, with the main representatives being Crohn’s disease and ulcerative colitis. Although there are still many unknown factors regarding the etiology and pathophysiology of this disease, it is believed to involve a complex interplay between genetic, epithelial, environmental, microbial, and immunological factors.

Considering that the number of affected patients is increasing worldwide and overall disease management often requires complex and expensive testing, there is a need for convenient, non-invasive, and economical solutions. It is becoming clear that molecular biomarkers are starting to represent a key component in IBD studies, as they can fulfil our requirements and potentially improve numerous areas in IBD management, including timely diagnosis, treatment response, the monitoring of disease activity, and mucosal healing. However, as the current most widely used biomarkers in IBD have certain shortcomings, there is substantial room for improvement and new studies in this field.

Therefore, the main goal of the upcoming Special Issue is to feature the most comprehensive and up-to‑date original research and specialized reviews helping to encompass and improve knowledge regarding molecular biomarkers that play significant roles in the complex pathophysiological pathways of IBD development, as well as exploring their potential to become new, effective, and reliable tools in disease monitoring, treatment strategies, and precision medicine.

Ulcerative colitis (UC) is a chronic inflammatory disorder of the large intestine. Data on the comparative effectiveness of biological therapies such as vedolizumab (VDZ) and ustekinumab (UST) remain limited. This retrospective study compared the effectiveness and safety of VDZ and UST in UC patients. Between November 2018 and November 2023, 106 patients were included: 64 received VDZ and 42 received UST. Bio-failure was significantly higher (p = 0.005) in the UST group versus the VDZ group. The remission rates at 6, 22, and 54 weeks in VDZ group were 51.6%, 61.3%, and 66.7%. The remission rates at 8, 24, and 56 weeks in the UST group were 66.7%, 65.0%, and 66.7%, respectively. Both treatments were comparable in inducing and maintaining clinical remission over 54–56 weeks, with no significant differences observed in the Lichtiger clinical activity index. Subgroup analyses highlighted the potential short-term effectiveness of UST among cases of bio-failure and a white blood cell level ≥ 9000/µL. Safety profiles were generally favorable, with no significant adverse events. Usutekinumab demonstrated effectiveness as a salvage therapy in patients who failed VDZ. Despite the increased disease severity in the UST group compared to the VDZ group, both groups demonstrated similar remission rates, suggesting UST shows significant efficacy even in moderate to severe UC.
