Introduction: Following ileocolic resection (ICR), the clinical importance and prognostic implications of histologic activity on biopsies in Crohn's disease (CD) patients with endoscopic remission are not well defined. The aim of this study was to determine if histologic activity in patients with endoscopic remission is associated with future risk of endoscopic and/or radiologic postoperative recurrence (POR).

Methods: In this multicenter retrospective cohort study, adult patients with CD who underwent ICR between 2009 and 2020 with endoscopic biopsies of ileal mucosa from Rutgeerts i0 on index colonoscopy were included.

Background & Aims: Despite increasing therapeutic options in the treatment of ulcerative colitis (UC), achieving disease remission remains a major clinical challenge. Nonresponse to therapy is common and clinicians have little guidance in selecting the optimal therapy for an individual patient. This study examined whether patient-derived materials could predict individual clinical responsiveness to the Janus kinase (JAK) inhibitor, tofacitinib, prior to treatment initiation.

Background: Fecal calprotectin (FC) is a reliable predictor of active bowel inflammation in postoperative Crohn's disease (CD), but cutoffs vary between studies. Recent guidelines recommend a cutoff of <50 ug/g to avoid routine endoscopy in patients at low pretest probability for CD recurrence. We evaluated the performance of this threshold in a real-world CD cohort after ileocolic resection (ICR).

The inflammatory bowel diseases (IBDs), comprising Crohn’s disease and ulcerative colitis (UC), are chronic inflammatory conditions of the gastrointestinal tract. Individuals with IBD are at an increased risk of developing intestinal neoplasia, particularly colorectal neoplasia (CRN) (including colorectal dysplasia and colorectal cancer [CRC]), as a consequence of chronic colonic inflammation. Given that CRC in patients with IBD appears to be preceded by dysplastic changes in the colonic mucosa, prevention strategies to reduce CRC-associated morbidity and mortality have been recommended by multiple society guidelines and independent consensus groups, and include risk assessment, mitigation of inflammation with medical therapies, and screening and surveillance strategies with colonoscopy, with histopathologic assessments at appropriate intervals.

Background: Inflammatory bowel disease is a chronic, relapsing, and remitting inflammatory disorder that despite advances in medical therapy often requires hospitalization for treatment of acute flares with intravenous corticosteroids. Many patients will not respond to corticosteroids and require infliximab or cyclosporine as rescue therapy. If medical therapy fails, definitive surgical management is required.

Background & Aims: Inflammatory bowel disease (IBD) is linked to reduced female fertility, but it is unclear how fertility rates vary by histologic disease activity.

Methods: Nationwide IBD cohort of Swedish women aged 15 to 44 years. We examined fertility rates during periods with vs without histologic inflammation (n = 21,046; follow-up, 1990-2016) and during periods with vs without clinical activity (IBD-related hospitalization, surgery, or treatment escalation) (n = 24,995; follow-up, 2006-2020).

In recent years, legislation targeting the sexual and gender minority (SGM) community has been passed at an increasingly alarming rate, affecting access to safe and effective gender-affirming care and forcing many SGM patients, including those with inflammatory bowel disease (IBD), to withhold their identities and health concerns. Additionally, SGM patients with IBD may have unique health considerations that have not yet been well-studied OBJECTIVE: This article aims to explore the intersection of IBD and sexual health in patients who identify as SGM and to identify limitations for gastroenterologists in caring for SGM patients. The article also aims to provide suggestions for improvement in SGM-competent care within gastroenterology METHODS: A thorough literature review was conducted regarding sexual health and the SGM community with IBD.

Effective immunity requires a large, diverse naive T cell repertoire circulating among lymphoid organs in search of antigen. Sphingosine 1-phosphate (S1P) and its receptor S1PR1 contribute by both directing T cell migration and supporting T cell survival. Here, we addressed how S1P enables T cell survival and the implications for patients treated with S1PR1 antagonists.

Background: In ulcerative colitis (UC), endoscopic improvement, defined as a Mayo Endoscopic Score (MES) of 0 or 1, is a target of treatment. The aim of our study was to evaluate the risk of clinical relapse between patients with an MES of 0 or 1 and determine if histologic activity using the Robarts Histopathologic Index (RHI) was predictive of clinical relapse.

Methods: UC patients with an MES score of 0 or 1, no prior colectomy, and at least 1 year of outpatient follow-up after colonoscopy were included.

The immune response to SARS-CoV-2 antigen after infection or vaccination is defined by the durable production of antibodies and T cells. Population-based monitoring typically focuses on antibody titer, but there is a need for improved characterization and quantification of T cell responses. Here, we used multimodal sequencing technologies to perform a longitudinal analysis of circulating human leukocytes collected before and after immunization with the mRNA vaccine BNT162b2.

Introduction: Data suggest atherosclerotic-related inflammation may play a role in the pathogenesis of inflammatory bowel disease (IBD), but large-scale studies are missing.

Methods: In this nationwide case-control study, we used the Swedish Patient Register and the Epidemiology Strengthened by histoPathology Reports in Sweden cohort to identify adult cases of incident IBD between 2002 and 2021, with each case matched to up to 10 general population controls. We used conditional logistic regression to calculate odds ratios (OR) for exposure to an atherosclerotic-related condition (myocardial infarction, thromboembolic stroke, or atherosclerosis itself) before being diagnosed with IBD.

Loss of antimicrobial proteins such as REG3 family members compromises the integrity of the intestinal barrier. Here, we demonstrate that overproduction of REG3 proteins can also be detrimental by reducing a protective species in the microbiota. Patients with inflammatory bowel disease (IBD) experiencing flares displayed heightened levels of secreted REG3 proteins that mediated depletion of Enterococcus faecium (Efm) from the gut microbiota.
