Inflammatory Bowel Diseases (IBD) is a systemic disorder with possible renal involvement, yet data regarding the outcome of kidney transplantation (KT) in those patients, and IBD course post KT, are scarce. In this retrospective analysis, we studied the outcome of 12 IBD kidney recipients (7 Crohn's disease, 5 ulcerative colitis; primary kidney disease was IgA nephropathy in 5, polycystic disease in 4), compared to two control groups: matched-controls, and a cohort of recipients with similar kidney disease. During a follow-up period of 60. Read More

Background And Aims: Measuring quality of care (QoC) in inflammatory bowel diseases (IBD) has become increasingly important, yet complex assessment of QoC from the patients' perspective is rare. We evaluated perceived QoC using the Quality of Care Through the Patient's Eyes - IBD (QUOTE-IBD) questionnaire, and investigated associations between QoC, disease phenotype, work productivity and health-related quality of life (HRQoL) in a high-volume IBD center.

Methods: Consecutive patients attending McGill University Health Centre (MUHC)-IBD Center completed the QUOTE-IBD, Short Inflammatory Bowel Disease Questionnaire (SIBDQ), IBD-Control and Work Productivity and Activity Impairment (WPAI) questionnaires. Read More

The intestinal tract is inhabited by a tremendous number of microorganisms, termed the gut microbiota. These microorganisms live in a mutualistic relationship with their host and assist in the degradation of complex carbohydrates. Although the gut microbiota is generally considered beneficial, the vast number of microbial cells also form a permanent threat to the host. Read More

Introduction: Many of the therapeutic options for patients with inflammatory bowel disease (IBD) suppress the immune system, which increases the risk of certain infections in these patients. Effective vaccines exist and offer protection against a number of infectious diseases. However, data has shown that IBD patients are inadequately vaccinated and, as a result, are at risk of developing certain preventable infections. Read More

The IBDs, Crohn's disease and ulcerative colitis, are chronic inflammatory conditions of the gastrointestinal tract resulting from an aberrant immune response to enteric microbiota in genetically susceptible individuals. Disease presentation and progression within and across IBDs, especially Crohn's disease, are highly heterogeneous in location, severity of inflammation and other phenotypes. Current clinical classifications fail to accurately predict disease course and response to therapies. Read More

Preclinical studies have demonstrated that the endocannabinoid system (ECS) plays an important role in the protection against intestinal inflammation and colorectal cancer (CRC); however, human data are scarce. We determined members of the ECS and related components of the 'endocannabinoidome' in patients with inflammatory bowel disease (IBD) and CRC, and compared them to control subjects. Anandamide (AEA) and oleoylethanolamide (OEA) were increased in plasma of ulcerative colitis (UC) and Crohn's disease (CD) patients while 2-arachidonoylglycerol (2-AG) was elevated in patients with CD, but not UC.

The aim of the present study was to determine the influence of stress on the colonic mucosa and immune system and to further investigate the association between stress and development and pathogenesis of ulcerative colitis (UC). Mice were treated with 2,4,6-trinitrobenzenesulfonic acid to induce an animal model of UC, and stress was induced by water immersion and restraint. Subsequently, the disease activity index (DAI), secretory immunoglobulin A (sIgA), IgA, interleukin (IL)-6 and -8, tumor necrosis factor-α (TNF-α), complement component (C)3 and C4, and alterations in the colonic mucosa were observed.

Introduction: Crohn's disease (CD) and ulcerative colitis (UC) are remitting-relapsing inflammatory diseases often culminating in disease complications and/or need for surgery. Biologic monoclonal antibody drugs ('Biologics') are efficacious for both diseases, but there are no systematic assessments of their efficacy if administered early after disease onset ('top-down' strategy) vis-à-vis later in the course of disease ('step-up' approach).

Introduction: Acute severe ulcerative colitis (ASUC) is a severe manifestation of ulcerative colitis (UC) that warrants hospitalisation. Despite significant advances in therapeutic options for UC and in the medical management of steroid-refractory ASUC, the initial treatment paradigm has not changed since 1955 and is based on the use of intravenous corticosteroids. This treatment is successful in approximately 50% of patients but failure of this and subsequent medical therapy still occurs, with colectomy rates of up to 40% reported. Read More
