Combining Advanced Targeted Therapy in Inflammatory Bowel Disease: Current Practice and Future Directions.

Despite the increasing number of available medications, a significant proportion of IBD patients fail to achieve the current therapeutic targets. Uncontrolled IBD has a significant impact on patients' quality of life and on overall costs for the healthcare system. Given the complex pathophysiology of IBD, Combined Advanced Targeted Therapy (CATT), involving the combination of biologics/small molecules, appears to have biological plausibility and is gaining increasing interest.

Noninvasive Assessment of Postoperative Disease Recurrence in Crohn's Disease: A Multicenter, Prospective Cohort Study on Behalf of the Italian Group for Inflammatory Bowel Disease.

Background & Aims: Colonoscopy (CS) is the gold standard to assess postoperative recurrence (POR) in Crohn's disease (CD). However, CS is invasive and may be poorly tolerated by patients. The aim of this study was to prospectively assess the diagnostic accuracy of a noninvasive approach in detecting POR, using the endoscopic Rutgeerts' score (RS) as the reference standard.

Rediscovering histology: what is new in endoscopy for inflammatory bowel disease?

The potential of endoscopic evaluation in the management of inflammatory bowel diseases (IBD) has undoubtedly grown over the last few years. When dealing with IBD patients, histological remission (HR) is now considered a desirable target along with symptomatic and endoscopic remission, due to its association with better long-term outcomes. Consequently, the ability of endoscopic techniques to reflect microscopic findings without having to collect biopsies has become of upmost importance.

TL1A: A New Potential Target in the Treatment of Inflammatory Bowel Disease.

Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic inflammatory diseases of the gastrointestinal tract. In the last few years, the development of biological agents targeting cytokines and receptors involved in IBD pathogenesis has led to better outcomes and has improved the course of the disease. Despite their effectiveness, drugs such as tumor necrosis factor (TNF) inhibitors, anti-Interleukin-12/23 and anti-integrins, do not induce a response in about one-third of patients, and 40% of patients lose response over time.

New Paradigms to Help Decisions in Treatment Choice: Head to Head Trial of Biological Therapies in Inflammatory Bowel Diseases.

The increasing armamentarium of drugs for inflammatory bowel disease (IBD) requires a direct comparison of different therapeutic options in order to guide physicians in the choice of the most appropriate treatment for their patients. Head-to-head trials, considered the gold standard in comparative research in IBD, allow to compare different therapies in the same population and setting, but also to evaluate different treatment strategies. Although head-to-head trials including biologics and immunosuppressive therapy in IBD have been performed decades ago, the interest in these direct comparisons is growing since the publication of the first randomized controlled trial directly comparing biologic agents with different molecular targets.

Application of Ultrasound Elastography for Assessing Intestinal Fibrosis in Inflammatory Bowel Disease: Fiction or Reality?

Background: Intestinal fibrosis and subsequent strictures represent an important burden in inflammatory bowel disease (IBD). Both the detection and evaluation of the degree of fibrosis in stricturing Crohn's disease (CD) are important when deciding the best therapeutic strategy (medical anti-inflammatory therapy, endoscopic dilation, surgery). Ultrasound elastography (USE) is a non-invasive technique that has been proposed in the field of IBD for evaluating intestinal stiffness as a biomarker of intestinal fibrosis.

Validation of the Red Flags Index for Early Diagnosis of Crohn's Disease: A Prospective Observational IG-IBD Study Among General Practitioners.

Introduction: Diagnostic delay >12 months is frequent in Crohn's disease [CD]. Recently, the International Organization for Inflammatory Bowel Disease [IO-IBD] developed a tool to identify early CD and reduce diagnostic delay. Subjects with an index ≥8 are more likely to have suspected CD (odds ratio [OR] 205, p <0.

Absence of COVID-19 Infection in Patients Accessing IBD Unit at Humanitas, Milan: Implications for Postlockdown Measures.

Introduction: The risk of coronavirus disease-19 infection for healthcare professionals and patients in hospitals remains unclear.

Methods: 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.

Results: Three hundred-twenty patients with IBD were included.

Endoscopy after surgery in inflammatory bowel disease: Crohn's disease recurrence and pouch surveillance.

Introduction: Crohn's disease (CD) and ulcerative colitis (UC) are immune-mediated disorders characterized by a chronic inflammation, with intermittent exacerbations of symptoms and inflammation. In both diseases, medical treatment has made revolutionary steps forward. Nevertheless, surgery is still required in many cases due to inefficacy of multiple medical therapies.

Targeting the gut layers in Crohn's disease: mucosal or transmural healing?

Introduction: Although the landmark of Crohn's Disease (CD) is the transmural inflammation, mucosal healing (MH), which is assessed by colonoscopy, is currently the gold standard of CD management. Transmural healing (TH) is a new concept evaluated by cross-sectional imaging (CSI) techniques, such as bowel ultrasound (US), computed tomography enterography (CTE), and magnetic resonance enterography (MRE). Little is known about the clinical significance of persisting mural disease and the predictive value of complete TH.

Incidence and Patterns of COVID-19 Among Inflammatory Bowel Disease Patients From the Nancy and Milan Cohorts.

The first cases of COVID-19 infection were reported in December, 2019, in Wuhan, China. Italy (in particular Lombardy) and France (in particular Northeast) have been gravely hit. Both physicians and inflammatory bowel disease (IBD) patients are deeply concerned that immunosuppressants or biologics may increase the risk of COVID-19 infection.

Maintaining the Quality Standards of Care for Inflammatory Bowel Disease Patients During the COVID-19 Pandemic.

Since February 20, 2020, the SARS-COV2 infection has spread in Lombardy, and in the rest of the Italian regions, forcing our government to impose a national lockdown. Hospitals have been forced to adapt and to restructure their units to cope with this urgent new critical situation. Alternative solutions have been found to manage patients with inflammatory bowel disease (IBD), including remote monitoring, drug home delivery, limitations for infusion units, and patient education on measures to prevent infection, to maintain high-quality care.

Inflammatory Bowel Disease Care in the COVID-19 Pandemic Era: The Humanitas, Milan, Experience.

The outbreak of the COVID-19 caused by coronavirus SARS-CoV2, is rapidly spreading worldwide. This is the first pandemic caused by a coronavirus in history. More than 150 000 confirmed cases worldwide are reported involving the SARS-CoV2, with more than 5000 COVID-19-related deaths on March 14, 2020.

Quality of Care Standards in Inflammatory Bowel Diseases: a European Crohn's and Colitis Organisation [ECCO] Position Paper.

The management of inflammatory bowel disease [IBD] is complex, and requires tight control of disease activity, close monitoring to avoid treatment side effects, health care professionals with expertise in IBD, and an interdisciplinary, holistic approach. Despite various efforts to standardise structures, processes, and outcomes,1-8 and due to the high variability at the local, national, and international levels, there are still no clear definitions or outcome measures available to establish quality of care standards for IBD patients which are applicable in all contexts and all countries. For this reason, the European Crohn's and Colitis Organisation [ECCO] supported the construction of a list of criteria summarising current standards of care in IBD.

Is there a role for therapeutic sphingolipids in inflammatory bowel disease?

: Inflammatory bowel diseases (IBD), which include Crohn's disease and ulcerative colitis, are lifetime chronic inflammatory disorders. Over the past few decades, new therapeutic approaches, including early and more effective intervention with immunomodulators and biological agents, increased the possibility of a favorable modification of the natural history of IBD. Despite this progress, there is still a need to explore new therapeutic options.

Multidisciplinary management of the nocebo effect in biosimilar-treated IBD patients: Results of a workshop from the NOCE-BIO consensus group.

The high cost of biological drugs for patients with inflammatory bowel disease (IBD) considerably impacts on health-care budgets. Since the patent of biological products expired, cheaper biosimilars have entered the market. Available data coming from real-world cohorts and clinical trials indicate that the efficacy and safety of biosimilars is comparable to that of the originator drugs.

Comorbidities in inflammatory bowel disease: a call for action.

Inflammatory bowel disease (IBD) is a chronic systemic inflammatory condition. Previously, the focus has been on extraintestinal manifestations of IBD, including arthritis, psoriasis, and uveitis. Although comorbidities have long been the subject of intensive research in other chronic inflammatory diseases such as rheumatoid arthritis, the concept of comorbidities is only beginning to emerge in IBD.

Consensus report: clinical recommendations for the prevention and management of the nocebo effect in biosimilar-treated IBD patients.

Background: The nocebo effect is a negative effect of a pharmacological or nonpharmacological medical treatment that is induced by patients' expectations, and that is unrelated to the physiological action of the treatment. The nocebo effect can negatively affect treatment outcomes.

Aim: To develop evidence-based consensus recommendations for the prevention and management of the nocebo effect in biosimilar-treated patients with IBD.

Prevention of Postoperative Recurrence in CD: Tailoring Treatment to Patient Profile.

Crohn's disease (CD) is an immune-mediated condition characterized by the transmural inflammation of the gut tissue, associated with progressive bowel damage often leading to surgical intervention. As operative resection of the damaged segment is not curative, a majority of patients undergoing intestinal resections for complicated CD present disease recurrence within 3 years after the intervention. Postoperative recurrence can be defined as endoscopic, clinical, radiological or surgical.

Anti-fibrotic Drugs for Crohn's Disease: Ready for Prime Time?

Intestinal fibrosis, driven by chronic inflammation in Crohn's disease, can be defined as an excessive accumulation of extracellular matrix in the affected gut segment ultimately leading to an impaired wound healing and cumulative tissue damage, possibly resulting in organ dysfunction, formation of stenotic lesions and necessity of surgical intervention. Despite continuous advances in developing novel treatment modalities targeting different pathways to control chronic gut inflammation in CD, no effective anti-fibrotic agents have been released, to date. Thus, a better understanding of the molecular and cellular mechanisms underlying intestinal fibrosis is key to move this area of investigation forward.
