The EXTENT Study: Results From an International Expert Delphi Consensus to Define Ultrasonographic Parameters for Measuring Bowel Damage in Crohn's Disease.

Background & Aims: A primary aim in managing Crohn's disease (CD) is preventing bowel damage. The Lémann index (LI) quantifies structural bowel damage using magnetic resonance enterography (MRE) or computed tomography enterography (CTE) and, for colonic CD, colonoscopy. Intestinal ultrasonography (IUS) provides a noninvasive imaging alternative, although its role in LI assessment remains unexplored.

Enteral Nutrition in Crohn's Disease: A Comprehensive Review of Its Role in Induction and Maintenance of Remission and Perioperative Management in Adult Patients.

Crohn's disease (CD) is a chronic inflammatory bowel disorder frequently associated with significant nutritional deficiencies. Enteral nutrition (EN), particularly exclusive enteral nutrition (EEN), has gained recognition not only for its nutritional support but also for its therapeutic potential in reducing intestinal inflammation. While EEN is well established in pediatric populations, its application in adults remains limited due to lower adherence and palatability challenges.

Steroid-Refractory Acute Severe Ulcerative Colitis in Infliximab-Experienced Patients.

Acute severe ulcerative colitis (ASUC) is a potentially life-threatening complication of ulcerative colitis (UC) that can lead to significant morbidity and mortality, with a substantial number of patients needing colectomy. Infliximab (IFX) has been increasingly used as a rescue therapy for patients who have failed intravenous steroids and has been more frequently used as an induction and maintenance therapy in moderate-to-severe UC. Therefore, the number of patients admitted with ASUC previously exposed to IFX has been increasing, raising additional challenges in the medical management of these patients to avoid emergent colectomy.

Narrow Band Imaging versus White Light for the Detection of Sessile Serrated Colorectal Lesions: A Randomized Clinical Trial.

Background: Colorectal cancer (CRC) is a leading cause of cancer. The detection of pre-malignant lesions by colonoscopy is associated with reduced CRC incidence and mortality. Narrow band imaging has shown promising but conflicting results for the detection of serrated lesions.

Early intervention with biologic therapy in Crohn´s disease: how early is early?

Background: Early biologic therapy within the first 18-24 months after diagnosis is associated with improved clinical outcomes in Crohn's disease [CD]. However, the definition of the best time to initiate biologic therapy remains unclear. We aimed to assess if there is an optimal timing for early biologic therapy initiation.

Groove Pancreatitis: Clinical Cases and Review of the Literature.

Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain.

Intestinal Ultrasound in Inflammatory Bowel Disease: A Valuable and Increasingly Important Tool.

Background: Intestinal ultrasound is emerging as a non-invasive tool for monitoring disease activity in inflammatory bowel disease patients due to its low cost, excellent safety profile, and availability. Herein, we comprehensively review the role of intestinal ultrasound in the management of these patients.

Summary: Intestinal ultrasound has a good accuracy in the diagnosis of Crohn's disease, as well as in the assessment of disease activity, extent, and evaluating disease-related complications, namely strictures, fistulae, and abscesses.

Early Ultrasound Response and Progressive Transmural Remission After Treatment With Ustekinumab in Crohn's Disease.

Background & Aims: In this STARDUST substudy, the effect of ustekinumab on transmural bowel inflammation was assessed in adults with moderate-to-severe Crohn's disease (CD) by using intestinal ultrasound (IUS), a noninvasive imaging procedure.

Methods: STARDUST was an international, multicenter, phase 3b, interventional, randomized controlled trial specifically designed to compare treat-to-target and standard-of-care treatment strategies in ustekinumab-treated CD patients. In this substudy, the most affected bowel segment at baseline by IUS was used for all analyses.

Secondary Sclerosing Cholangitis in a Critically Ill Patient with Severe SARS-CoV-2 Infection: A Possibly Emergent Entity during the Current Global Pandemic.

A 46-year-old woman without previous history of hepatobiliary disease was admitted to the intensive care unit due to SARS-CoV-2 infection. Admission blood tests revealed impending hyperinflammation in the context of systemic inflammatory response syndrome. She required 12 days of mechanical ventilation and vasopressor support.

The knowledge and skills needed to perform intestinal ultrasound for inflammatory bowel diseases-an international Delphi consensus survey.

Aim: To achieve international consensus on what competencies should be expected from a newly certified IUS practitioner.

Inflammatory Bowel Disease Patients' Perspectives during COVID-19 Pandemic: Results from a Portuguese Survey.

Introduction: Patients with inflammatory bowel disease (IBD) do not seem to be at increased risk of infection by SARS-CoV-2, but there is a concern whether immunosuppressive therapy may be associated with more severe disease. Several clinical practice recommendations have been published to help guide IBD care during the COVID-19 pandemic. Nonetheless, few studies have addressed patients' perspectives and fears.

Defining Transabdominal Intestinal Ultrasound Treatment Response and Remission in Inflammatory Bowel Disease: Systematic Review and Expert Consensus Statement.

Background And Aims: No consensus exists on defining intestinal ultrasound response, transmural healing, or transmural remission in inflammatory bowel disease, nor clear guidance for optimal timing of assessment during treatment. This systematic review and expert consensus study aimed to define such recommendations, along with key parameters included in response reporting.

Methods: Electronic databases were searched from inception to July 26, 2021, using pre-defined terms.

Patients with Inflammatory Bowel Disease Are Not at Increased Risk of COVID-19: A Large Multinational Cohort Study.

The impact of COVID-19 on inflammatory bowel disease (IBD) patients under pharmacological immunosuppression is still not clearly understood. We investigated the incidence of COVID-19 and the impact of immunosuppression and containment measures on the risk of SARS-CoV-2 infection in a large IBD cohort, from a multicenter cohort from 21st of February to 30th of June, 2020. Ninety-seven patients with IBD (43 UC, 53 CD, one unclassified IBD) and concomitant COVID-19 over a total of 23,879 patients with IBD were enrolled in the study.

Expert Consensus on Optimal Acquisition and Development of the International Bowel Ultrasound Segmental Activity Score [IBUS-SAS]: A Reliability and Inter-rater Variability Study on Intestinal Ultrasonography in Crohn's Disease.

Background And Aims: Intestinal ultrasound [IUS] is an accurate, patient-centreed monitoring tool that objectively evaluates Crohn's disease [CD] activity. However no current, widely accepted, reproducible activity index exists to facilitate consistent IUS identification of inflammatory activity. The aim of this study is to identify key parameters of CD inflammation on IUS, evaluate their reliability, and develop an IUS index reflecting segmental activity.

Febrile Neutropenia in Patients with Solid Tumors Undergoing Intravenous Chemotherapy.

Introduction: Febrile neutropenia (FN) is a potentially life-threatening complication of systemic chemotherapy (CT) that often requires hospital admission. Delay in diagnosis and treatment are associated with higher morbidity and mortality.

Objective: We aimed to determine the factors that influence FN episodes outcomes in the emergency room (ER).

Preoperative enteral nutrition in adults with complicated Crohn's disease: Effect on disease outcomes and gut microbiota.

Objectives: The use of exclusive enteral nutrition (EEN) in patients with Crohn's disease (CD) before surgical resection can reduce disease activity and improve nutritional status. The mechanism of EEN action is unclear, but it might involve modulation of the intestinal microbiota. The aim of this study was to evaluate the effects (namely changes in gut microbiota) of preoperative EEN in adults with complicated CD referred to surgery.

Rare case of a giant duodenal ulcer penetrating the pancreas during antiangiogenic treatment.

We report a case of a patient with renal cell carcinoma on pazopanib, who presented with severe upper gastrointestinal bleeding. Endoscopy showed a giant bulbar ulcer with a visible vessel of 4 mm. Due to unavailability of surgical rescue backup, large calibre vessel treatment was delayed.

European Crohn's and Colitis Organisation Topical Review on Complementary Medicine and Psychotherapy in Inflammatory Bowel Disease.

Patients with inflammatory bowel disease [IBD] increasingly use alternative and complementary therapies, for which appropriate evidence is often lacking. It is estimated that up to half of all patients with IBD use various forms of complementary and alternative medicine during some point in their disease course. Considering the frequent use of such therapies, it is crucial that physicians and patients are informed about their efficacy and safety in order to provide guidance and evidence-based advice.

Lower skeletal muscle attenuation and high visceral fat index are associated with complicated disease in patients with Crohn's disease: An exploratory study.

Background And Aims: The prognostic value of body composition analysis in patients with Crohn's disease (CD) is poorly explored. The aims of the present study were to assess fat and skeletal muscle compartments including muscle radiation attenuation (MA) in patients with CD, and to analyze its predictive value to identify complicated phenotypes.

Methods: Seventy one patients with CD who have had an abdominal CT within one month of clinical, laboratory, and endoscopic evaluation were included.

Withdrawal of immunosuppressant or biologic therapy for patients with quiescent Crohn's disease.

Background: Crohn's disease (CD) is a chronic, relapsing and remitting disease of the gastrointestinal tract that can cause significant morbidity and disability. Current treatment guidelines recommend early intervention with immunosuppressant or biological therapy in high-risk patients with a severe disease phenotype at presentation. The feasibility of therapeutic de-escalation once remission is achieved is a commonly encountered question in clinical practice, driven by patient and clinician concerns regarding safety, adverse events, cost and national regulations.

Consecutive negative findings on colonoscopy during surveillance predict a low risk of advanced neoplasia in patients with inflammatory bowel disease with long-standing colitis: results of a 15-year multicentre, multinational cohort study.

Objectives: Surveillance colonoscopy is thought to prevent colorectal cancer (CRC) in patients with long-standing colonic IBD, but data regarding the frequency of surveillance and the findings thereof are lacking. Our aim was to determine whether consecutive negative surveillance colonoscopies adequately predict low neoplastic risk.

Design: A multicentre, multinational database of patients with long-standing IBD colitis without high-risk features and undergoing regular CRC surveillance was constructed.

Farnesoid X Receptor Expression in Microscopic Colitis: A Potential Role in Disease Etiopathogenesis.

Introduction: Microscopic colitis (MC) is a chronic inflammatory bowel disease with unclear etiology. Bile acid (BA) malabsorption has been described in MC patients. Farnesoid X receptor (FXR) is the main BA receptor; FXR-mediated mechanisms prevent the noxious effects of BA accumulation, preserving the integrity of the intestinal epithelial barrier and preventing intestinal inflammation.
