Background: Data regarding care access and outcomes in Black/Indigenous/People of Color/Hispanic (BIPOC/H) individuals is limited. This study evaluated care barriers, disease status, and outcomes among a diverse population of White/non-Hispanic (W/NH) and BIPOC/H inflammatory bowel disease (IBD) patients at a large U.S.

The heterogeneous pathobiology underlying Ulcerative Colitis (UC) is not fully understood. Using publicly available transcriptomes from adult UC patients, we identified the immune cell landscape, molecular pathways, and differentially expressed genes (DEGs) across patient cohorts and their association with treatment outcomes. The global immune cell landscape of UC tissue included increased neutrophils, T CD4 memory activated cells, active dendritic cells (DC), and M0 macrophages, as well as reduced trends in T CD8, Tregs, B memory, resting DC, and M2 macrophages.

Background: Oral vancomycin (OV) in primary sclerosing cholangitis (PSC) has been evaluated as a potential therapeutic agent. We report the long-term biochemical course and outcomes of patients with PSC treated with OV.

Methods: Patients were enrolled in 2 open-label clinical trials (ClinicalTrials.

Objectives: Gluten sensitivity (GS) arises with celiac disease and has also been found in non-celiac disorders, although its characteristics in inflammatory bowel disease (IBD) are unclear. This study evaluated the prevalence of GS and factors associated with GS in IBD.

Methods: Adult IBD patients at a tertiary-care medical center completed a survey of their demographics, medical history, family history, social history and symptoms.

Background: While previous studies have evaluated caregivers' quality of life (QOL), burnout, and stress amongst across a variety of chronic illnesses, few such studies have been related to inflammatory bowel disease (IBD).

Methods: Caregivers accompanying adult patients with IBD at 6 tertiary centers were enrolled. They completed self-administered surveys related to QOL and burden, including the QOL scale, Zarit Burden Interview (ZBI), and Brief COPE.

Objectives: Symptoms of and treatments for inflammatory bowel disease (IBD) have a significant impact on patients' quality of life (QOL) and result in an increased prevalence of depression and anxiety disorders. Little is known about the type of coping strategies used by adult patients with IBD to better cope with their chronic illness, however. The objectives of this study were to identify the types of coping styles and their impact on the QOL of patients with IBD.

Background & Aims: Although the prevalence of anal dysplasia is higher in some immunosuppressed populations, the prevalence in patients with inflammatory bowel disease (IBD) is unknown. We examined the prevalence of abnormal anal cytology among IBD patients, and its relation to the human papilloma virus (HPV).

Methods: Adults with IBD and age-matched healthy controls (HC) were recruited.

Background And Aim: Intestinal and extra-intestinal complications are associated with inflammatory bowel disease (IBD) but their exact incidence is not well known. In order to improve our understanding of their incidence and impact, we assessed the complications associated with ulcerative colitis (UC) and Crohn's disease (CD) in a population-based study in Medicaid patients.

Methods: We utilized a retrospective cohort design and identified cases of UC and CD using Medi-Cal, the Medicaid program for the State of California.

With the introduction of biologic therapies for inflammatory bowel disease, significant questions have arisen regarding their best optimization. Although initial recommendations were to combine immunosuppressives with biologics to reduce immunogenicity, trials with 3 different anti-tumor necrosis factor agents (infliximab, adalimumab, and certolizumab) and a humanized monoclonal antibody that targets alpha-4 integrins (natalizumab) have failed to demonstrate the clinical superiority of combination therapy when high-dose induction and scheduled maintenance therapy was prescribed for up to 1 year. However, immunosuppressive agents should be considered with episodic biologic therapy to decrease immunogenicity and secondary loss of response.

Diarrhea continues to be a prevalent symptom in patients with inflammatory bowel disease (IBD), requiring a wide differential diagnosis to define the pathophysiologic mechanisms in individual patients. It is essential that physicians properly evaluate complaints of diarrhea by assessing both patient symptoms and potential physiologic impacts on fluid and electrolyte status. Underlying mechanisms of diarrhea with IBD are the location, extent, and severity of inflammation; malabsorption; altered motility; and iatrogenic causes such as medications, diet, and antibiotic-associated colitis (eg, Clostridium difficile).
