Psoriasis and inflammatory bowel disease: concomitant IMID or paradoxical therapeutic effect? A scoping review on anti-IL-12/23 and anti-IL-23 antibodies.

Inflammatory bowel diseases (IBD) and psoriasis are chronic inflammatory conditions belonging to the heterogeneous group of immune-mediated inflammatory diseases (IMIDs). A significant bidirectional link between these two entities has been observed, conditioning an increased risk of IBD in patients with psoriasis and vice-versa. Biological therapies used for IBD may lead to the occurrence of psoriasis as a "paradoxical reaction.

Ultrasound-guided percutaneous biopsy for challenging perihilar focal liver lesions: diagnostic accuracy and safety assessment.

Purpose: In cases of perihilar focal liver lesions, distinguishing between benign strictures and malignancies is critical to prevent unnecessary surgery. Although the use of contrast-enhanced CT or MRI in combination with clinical and laboratory findings can aid in diagnosis, histologic examination is often necessary. Histologic specimens can be obtained through various techniques, including ERCP-guided brush cytology or intraductal biopsy, cholangioscopy-directed biopsy or endoscopic ultrasound (EUS).

Background/objectives: Inflammatory bowel disease (IBD) and eosinophilic gastrointestinal diseases (EGIDs) are complex, multifactorial chronic inflammatory disorders affecting the gastrointestinal tract. Their epidemiology, particularly for eosinophilic esophagitis (EoE), is increasing worldwide, with a rise in the co-diagnosis of IBD and EGIDs. Both disorders share common risk factors, such as early exposure to antibiotics or specific dietary habits.

Reporting of Magnetic Resonance Enterography in Inflammatory Bowel Disease: Results of an Italian Survey.

Inflammatory bowel diseases (IBDs) are chronic disorders that require close monitoring with imaging techniques such as magnetic resonance enterography (MRE). Standardization of radiological reports is crucial for the optimal management of IBD. We surveyed Italian radiologists regarding their experiences with MRE examinations and reporting for IBD.

Management of proctitis in ulcerative colitis and the place of biological therapies.

Introduction: Approximately 20-30% of the patients with ulcerative colitis (UC) may present with isolated proctitis. Ulcerative proctitis (UP) is a challenging condition to manage due to its significant burden in terms of disabling symptoms.

Areas Covered: PubMed was searched up to March 2024 to identify relevant studies on UP.

Management of Post-Operative Crohn's Disease: Knowns and Unknowns.

Crohn's disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract characterized by relapsing-remission phases. CD often requires surgical intervention during its course, mainly ileo-cecal/ileo-colonic resection. However, surgery in CD is not curative and post-operative recurrence (POR) can happen.

Ophthalmological Manifestations in Inflammatory Bowel Diseases: Keep an Eye on It.

Background And Aims: Inflammatory bowel diseases (IBD) are multifactorial chronic inflammatory disorders affecting the gastrointestinal tract. However, a broad spectrum of extraintestinal manifestations (EIMs) is associated with IBD, affecting several organs and systems, such as the skin, musculoskeletal and hepatobiliary systems, and, not least, the eye. Approximately 10% of IBD patients can develop ocular EIMs (O-EIMs) with a higher prevalence in Crohn's disease (CD).

Treat-to-Target and Regular Surveillance of Inflammatory Bowel Disease Are Associated with Low Incidence and Early-Stage Detection of Malignancies: A Retrospective Cohort Study.

Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), increase the risk of malignancies, particularly colorectal cancer (CRC). We aimed to assess the incidence of malignancies in IBD patients managed using a treat-to-target approach and recommended surveillance. We retrospectively searched the electronic databases of two tertiary IBD centers in Milan from 2010 to 2019 for new diagnoses of malignancy in patients with pre-existing IBD.

Exploring the link: Porto-sinusoidal vascular disorder and inflammatory bowel disease - A comprehensive narrative review.

Porto-sinusoidal vascular disorder (PSVD) encompasses a group of vascular disorders characterized by lesions involving the portal venules and sinusoids, independent of the presence of portal hypertension (PH), and for which liver biopsy is essential for diagnosis. PSVD has been shown to be common in patients with immune-mediated diseases, including inflammatory bowel disease (IBD). The association between PSVD and the use of thiopurines and thioguanine in patients with IBD has been well established.

Lung Involvement in Inflammatory Bowel Diseases: Shared Pathways and Unwanted Connections.

Inflammatory bowel diseases (IBDs) are chronic, relapsing inflammatory disorders of the gastrointestinal tract, frequently associated with extraintestinal manifestations (EIMs) that can severely affect IBD patients' quality of life, sometimes even becoming life-threatening. Respiratory diseases have always been considered a rare and subsequently neglected extraintestinal manifestations of IBD. However, increasing evidence has demonstrated that respiratory involvement is frequent in IBD patients, even in the absence of respiratory symptoms.

Checkpoint Inhibitor-Induced Colitis: From Pathogenesis to Management.

The advent of immunotherapy, specifically of immune checkpoint inhibitors (ICIs), for the treatment of solid tumors has deeply transformed therapeutic algorithms in medical oncology. Approximately one-third of patients treated with ICIs may de velop immune-related adverse events, and the gastrointestinal tract is often affected by different grades of mucosal inflammation. Checkpoint inhibitors colitis (CIC) presents with watery or bloody diarrhea and, in the case of severe symptoms, requires ICIs discontinuation.

Atherosclerotic cardiovascular diseases in inflammatory bowel diseases: to the of the issue.

Atherosclerotic cardiovascular disease and stroke are the leading causes of morbidity and mortality worldwide. Along to the traditional risk factors for these diseases, chronic inflammation is known to be an important player in accelerating the process of atherosclerosis, which can result in an increased incidence of arterial thromboembolic events. As in other chronic inflammatory diseases, in the past few years, several studies suggested that subjects affected by inflammatory bowel diseases (IBD) may also be at an incremented risk of atherosclerotic disease, especially during the periods of disease's flare.

Fibro-Stenosing Crohn's Disease: What Is New and What Is Next?

Fibro-stenosing Crohn's disease (CD) is a common disease presentation that leads to impaired quality of life and often requires endoscopic treatments or surgery. From a pathobiology perspective, the conventional view that intestinal fibro-stenosis is an irreversible condition has been disproved. Currently, there are no existing imaging techniques that can accurately quantify the amount of fibrosis within a stricture, and managing patients is challenging, requiring a multidisciplinary team.

Mental Illnesses in Inflammatory Bowel Diseases: .

: Inflammatory bowel diseases (IBD) are chronic disorders associated with a reduced quality of life, and patients often also suffer from psychiatric comorbidities. Overall, both mood and cognitive disorders are prevalent in chronic organic diseases, especially in the case of a strong immune component, such as rheumatoid arthritis, multiple sclerosis, and cancer. Divergent data regarding the true incidence and prevalence of mental disorders in patients with IBD are available.

Pomegranate () can be used to prepare a bioactive extract exerting anti-inflammatory activities. Clinical studies demonstrated an improvement in clinical response in inflammatory bowel disease (IBD) patients when pomegranate extract () was taken as a complement to standard medications. However, the molecular mechanisms underlying its beneficial effects are still scarcely investigated.

Cytokines in Spondyloarthritis and Inflammatory Bowel Diseases: From Pathogenesis to Therapeutic Implications.

Spondyloarthritis and inflammatory bowel diseases are chronic immune disorders of the joints and the gut that often coexist in the same patient, increasing the burden of each disorder, worsening patients' quality of life, and influencing therapeutic strategies. Genetic predisposition, environmental triggers, microbiome features, immune cell trafficking, and soluble factors such as cytokines contribute to the pathogenesis of both articular and intestinal inflammation. Most of the molecular targeted biological therapies developed over the last two decades were based on evidence that specific cytokines may be involved in these immune diseases.

Artificial intelligence and inflammatory bowel disease: Where are we going?

Inflammatory bowel diseases, namely ulcerative colitis and Crohn's disease, are chronic and relapsing conditions that pose a growing burden on healthcare systems worldwide. Because of their complex and partly unknown etiology and pathogenesis, the management of ulcerative colitis and Crohn's disease can prove challenging not only from a clinical point of view but also for resource optimization. Artificial intelligence, an umbrella term that encompasses any cognitive function developed by machines for learning or problem solving, and its subsets machine learning and deep learning are becoming ever more essential tools with a plethora of applications in most medical specialties.

Technological advances in inflammatory bowel disease endoscopy and histology.

Accurate disease characterization is the pillar of modern treatment of inflammatory bowel disease (IBD) and endoscopy is the mainstay of disease assessment and colorectal cancer surveillance. Recent technological progress has enhanced and expanded the use of endoscopy in IBD. In particular, numerous artificial intelligence (AI)-powered systems have shown to support human endoscopists' evaluations, improving accuracy and consistency while saving time.

Gastrointestinal System: COVID-19 and Potential Mechanisms Associated with Coagulopathy.

SARS-CoV-2 is a novel coronavirus that expanded worldwide, generating a pandemic of acute respiratory syndrome called "coronavirus disease 2019" (COVID-19), which resulted in a global health crisis. The spectrum of COVID-19 manifestations ranges from none or mild symptoms to severe respiratory failure associated with systemic manifestations, mostly gastrointestinal symptoms. Hypercoagulability is an important feature of COVID-19 disease, which can potentially influence patients' prognosis.

Critical Appraisal of Filgotinib in the Treatment of Ulcerative Colitis: Current Evidence and Place in Therapy.

Background And Aims: Patients affected by moderate-to-severe Ulcerative Colitis (UC) demand a challenging management. Small molecules, administrated as oral agents, have the ambition of overcoming the limitations of the biologic agents (ie, parenteral administration, rapidity of action, primary and secondary non-responsiveness). Beyond tofacitinib, a pan-Janus kinase (JAK) inhibitor already approved for the treatment of moderate-to-severe UC, novel more selective molecules like filgotinib are being currently evaluated in randomized clinical trials.
