BackgroundInflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), continues to challenge treatment paradigms. Advancements in therapeutic options have been have been driven by Phase 2 and 3 clinical trials of new drug classes, particularly sphingosine-1-phosphate (S1P) modulators and interleukin-23 (IL-23) inhibitors.MethodsThis review synthesizes findings from Phase 2 and 3 clinical trials conducted up to early 2024, focusing on the impact of S1P modulators and IL-23 inhibitors on IBD management. Drugs such as ozanimod, etrasimod, risankizumab, mirikizumab, guselkumab, and brasikumab were evaluated for their efficacy and safety profiles.ResultsS1P modulators, such as ozanimod and etrasimod, effectively regulate immune cell trafficking to reduce inflammation and several trials highlight their clinical effectiveness in both inducing and maintaining remission in IBD, highlighting its long-term safety and sustained therapeutic effects. Additionally, IL-23 inhibitors including risankizumab, mirikizumab, and guselkumab, which disrupt key inflammatory cytokine pathways, have already shown significant effectiveness in inducing and maintaining remission in both CD and UC, with favorable safety profiles across multiple studies, suggesting their potential as critical components in managing IBD.ConclusionsThe clinical trials indicate that both S1P modulators and IL-23 inhibitors offer promising therapeutic benefits and maintain strong safety profiles, positioning them as potential cornerstone treatments for IBD. Despite these advancements, further exploration into long-term safety and the development of personalized treatment strategies is essential for maximizing clinical outcomes.

Intestinal ultrasound (IUS) is a non‐invasive and accurate tool to assess inflammatory bowel disease. The ECCO‐ESGAR guideline recommends the use of IUS for the assessment of disease activity and complications in Crohn's disease (CD). In addition, an increasing body of evidence suggests the use of IUS as alternative to colonoscopy in monitoring CD and in assessing disease activity of ulcerative colitis. Early responsiveness of IUS findings by the first weeks of treatment and the advantage to perform the procedure in real time may dramatically change frequency of the assessment of treatment response in the future and speed up the clinical decision‐making process. Development of validated and reproducible sonographic scores to measure disease activity and therapeutic response and spread of knowledge of IUS remain relevant issues for the future in which current researchers and the International Bowel Ultrasound (IBUS) Group are actively engaged.

The role of new psychological factors such as psychopathological patterns and defense mechanisms in the care of inflammatory bowel disease (IBD) has been poorly investigated. We aimed to assess the psychological characteristics and defense mechanisms of IBD patients. This was a single-center, observational, cross-sectional study. Consecutive adult IBD patients were enrolled and stratified according to disease activity. Sociodemographic and clinical data were collected, and validated questionnaires (Symptom Checklist-90-R [SCL-90-R]) for psychological distress, Defense Mechanism Inventory (DMI) for psychological defense mechanisms, and Inflammatory Bowel Disease Questionnaire (IBDQ) for quality of life (QoL) were administered. Two hundred one patients were enrolled: 101 in remission and 100 with active disease. The mean score for IBDQ was below the cutoff level (156.8 ± 37.8), with a significantly greater impairment of QoL in subjects with flares (136.5 vs 177.5, P < 0.001). Lower scores were associated with female gender. No patients had psychological scores above the cutoff for normality. Statistically higher SCL-90-R scores were found in active patients for obsessive-compulsive disorder (P = 0.026), depression (P = 0.013), anxiety (P = 0.013), phobic anxiety (P = 0.002), psychoticism (P = 0.007), global severity index (GSI) (P = 0.005) and positive symptom total (PST) (P = 0.001). A significantly increased probability of higher global indexes was associated with Crohn's disease and disease flares. None of the defensive Defense Mechanism Inventory (DMI) styles resulted above the cutoff in our cohort. Further data are needed to demonstrate the potential key role of psychological intervention in the therapeutic strategies utilized for IBD patients, and the identification of specific psychological patterns based on the patients profile is necessary to optimize psychological intervention.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by growing incidence and prevalence around the world in the last few decades. The range of available existing treatment and strategies for its management is being implemented. Given the introduction of newly developed molecules and the lack of specific guidelines, drug positioning may represent a tough clinical challenge. UC management is mostly medical, and it has been shifting toward a more personalized approach with the aim to create a tailored strategy depending on the patient’s profile. A treat-to target strategy seems to be the best approach to reach disease control as it allows to carry out therapeutic choices based on objective and specific parameters: histological, ultrasonographic, and molecular targets may add to the already used clinical, endoscopic, and biochemical targets. In addition, dual-targeted therapy has emerged as an attractive therapeutic strategy for patients not achieving remission. This review aims to provide an overview of the available strategies to raise the bar in UC. Plain language summary Raising the bar in ulcerative colitis management Ulcerative colitis is a chronic inflammatory bowel disease on the rise globally, particularly affecting individuals in their third to fifth decades of life and significantly impacting quality of life, with an increased risk of colorectal cancer. Available treatment options range from 5-aminosalicylates to advanced biological agents and small molecule drugs for moderate to severe UC. However, these advanced therapies pose challenges like non-response and immunogenicity, requiring precise therapy selection for sustained disease control and improved quality of life. In this context, timely intervention is crucial, with early diagnosis facilitating prompt treatment initiation and better remission rates. Advancements in monitoring techniques and drug optimization offer promise for refining treatment strategies and maximizing therapeutic efficacy. Thereby, medical management is shifting towards personalized approaches through tailored strategies based on patient profiles. A “treat-to-target” strategy, incorporating various parameters like endoscopic and histological ones alongside clinical ones, is pivotal for disease control. Moreover, dual targeted therapy has emerged as a possibility to treat difficult-to-treat patients. This review aims to outline available strategies for raising the bar in UC management.

The risk of coronavirus disease-19 infection for healthcare professionals and patients in hospitals remains unclear. We investigated whether precautions adopted in our inflammatory bowel disease (IBD) unit have minimized the risks of infection for all patients accessing our facilities in a 1-month period by assessing the rate of coronavirus disease-19 infection in the follow-up period. Three hundred-twenty patients with IBD were included. None were infected from severe acute respiratory syndrome-coronavirus 2 in the follow-up period. None of the IBD team members were infected. Neither pharmacological immunosuppression nor access to the hospital seem to be risk factors for infection in patients with IBD.

Introduction The aim of this study was to provide an external validation of bowel ultrasound (US) predictors of activity in ulcerative colitis (UC) and quantitative Milan Ultrasound Criteria (MUC). Methods Forty‐three consecutive patients with UC (16 in endoscopic remission and 27 with endoscopic activity) underwent bowel US and colonoscopy in a tertiary referral inflammatory bowel disease unit. Results An MUC score >6.2 discriminated patients with active versus non‐active UC with a sensitivity of 0.85 (95% confidence interval (CI) 0.66–0.96), specificity of 0.94 (95% CI 0.70–0.99) and an area under the curve of 0.902 (95% CI 0.772–0.971) in complete agreement with the derivation study. Conclusion The external validation of MUC confirms that it is an accurate tool for assessing disease activity in patients with UC.

In recent years, there has been a growing focus on the intricate interplay between the gut microbiota and host health, specifically in the context of inflammatory bowel diseases (IBDs). The gut microbiota produces a diverse array of metabolites, influencing the host’s immune response and tissue homeostasis. Noteworthy metabolites, such as short-chain fatty acids, bile acids, and indoles, exert significant effects on intestinal inflammation and fibrosis. This review integrates current research findings to clarify the mechanisms through which gut microbiota metabolites contribute to the progression of IBD and fibrosis, offering insights into potential therapeutic targets and strategies for managing these intricate gastrointestinal conditions. The unraveling of the complex relationship between gut microbiota metabolites and inflammatory processes holds promise for the development of targeted interventions that could lead to more effective and personalized treatment approaches for individuals affected by IBD and subsequent intestinal fibrosis.

Janus kinase inhibitors, including tofacitinib, filgotinib, and upadacitinib, have emerged as effective therapeutic options for the management of inflammatory bowel diseases (IBDs). By targeting the JAK-STAT signaling pathway, these agents modulate immune responses and reduce inflammation. However, concerns regarding the potential risk of malignancy associated with their use have gained significant attention. The JAK-STAT pathway is not only critical for inflammatory signaling but also plays a pivotal role in cellular growth, differentiation, and tumor surveillance. Observational studies and clinical trial data in rheumatoid arthritis have reported malignancies, including non-melanoma skin cancer and solid tumors, in patients receiving JAK inhibitors, with evidence suggesting variable risks depending on the selectivity of the agent. Current evidence does not suggest an increased risk of oncogenesis in patients with IBDs. Balancing therapeutic efficacy with long-term safety requires ongoing vigilance; patient stratification based on risk factors; and tailored monitoring strategies to mitigate potential adverse effects, including malignancies, during JAK inhibitor therapy. Long-term follow-up data of up to 10 years offer reassuring evidence that JAK inhibitor therapy in IBD patients does not confer an increased risk of malignancies, supporting their continued use within appropriate clinical settings.

Introduction: The introduction of biologic therapies and small molecule drugs has revolutionized the management of inflammatory bowel disease (IBD), providing targeted control of inflammation. However, concerns remain regarding their long-term safety profiles, particularly in relation to cancer risk. Chronic inflammation and immunosuppressive therapies contribute to malignancy risk, including skin cancers, such as melanoma and non-melanoma skin cancer (NMSC). This review examines the evidence on skin cancer risks associated with these therapies, focusing on specific drug classes and their mechanisms. Results: Tumor necrosis factor (TNF) inhibitors have shown conflicting evidence regarding melanoma risk, with some studies reporting a modest increase and others finding no significant association. Anti-integrin agents, such as vedolizumab, and interleukin (IL)-12/23 inhibitors, including ustekinumab, have demonstrated favorable safety profiles with minimal skin cancer risks. Selective IL-23 inhibitors and sphingosine-1-phosphate (S1P) receptor modulators have limited long-term data, but early findings indicate a low incidence of skin malignancies. Janus kinase (JAK) inhibitors do not show an increased risk of skin cancers in IBD. Conclusions: Current evidence suggests that skin cancer risk in IBD patients treated with biologics and small molecule drugs varies by drug class. TNF inhibitors and JAK inhibitors are associated with higher risks, while other therapies show lower malignancy risks. Regular skin cancer screening and protective measures remain critical, particularly for patients with additional risk factors. Further long-term studies are essential to refine safety profiles and inform clinical practice in this evolving therapeutic landscape.

Inflammatory bowel diseases (IBD) including Crohn’s disease (CD) and ulcerative colitis (UC) are chronic, relapsing conditions characterized by dysregulated immune responses and persistent intestinal inflammation. This review aims to examine new potential therapeutic targets in IBD starting from the STRIDE-II statements. Key targets now include clinical remission, endoscopic remission, and biomarker normalization (such as C-reactive protein and fecal calprotectin). Moreover, histologic remission, transmural remission, and in the future molecular targets are emerging as important indicators of sustained disease control. The treatment goals for inflammatory bowel disease are varied: to relieve symptoms, prevent permanent intestinal damage, promote inflammation remission, and minimize complications. Consequently, the therapeutic targets have evolved to become broader and more ambitious. Integrating these advanced therapeutic targets has the potential to redefine IBD management by promoting deeper disease control and improved patient outcomes. Further research is essential to validate these strategies and optimize their clinical implementation.
