UNLABELLED Crohn's disease (CD) and ulcerative colitis (UC) are multifactorial diseases with a genetic background. Recent results have shown that a non-synonymous, single nucleotide polymorphism (rs11209026, c.1142G>A, p.Arg381Gln) located in the IL-23R gene is associated with inflammatory bowel disease (IBD). The prevalence of IBD is rapidly rising in Chile and there is no information about th...

Aim To investigate the epidemiology and risk factors of Clostridium difficile infections (CDI) in patients with inflammatory bowel disease (IBD). Methods This is a retrospective study of patients diagnosed with IBD. 1006 charts were screened and 654 patients met the inclusion criteria. Patients were divided into 2 cohorts based on the presence of prior diagnosis of CDI. Statistical analysis w...

Understanding the causes and molecular mechanisms of Crohn’s disease and ulcerative colitis, the two forms of idiopathic chronic inflammatory bowel disease (IBD), is a major challenge in gastroenterology research. Significant eVort has been invested in uncovering genetic and environmental factors which may increase the risk of IBD, but progress has been slow, and no IBD specific factors have be...

Characteristic changes in the microbiota biostructure and a decreased tolerance to intestinal bacteria have been associated with inflammatory bowel disease (IBD). However, few studies have examined the constituents of the intestinal microbiota, including the surface molecules of the bacteria, in healthy and IBD subsets. Here, we compare the chemical structures and immunomodulatory properties of...

OBJECTIVES Inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC) compared to patients without IBD. There is a lack of population-based data evaluating the in-patient surgical outcomes of CRC in IBD patients. We sought to compare the hospital outcomes of CRC surgery between patients with and without IBD. METHODS We used the National Inpatient Sample (...

Cytokines play an important role in the immunopathogenesis of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, where they drive and regulate multiple aspects of intestinal inflammation. The imbalance between proinflammatory and anti-inflammatory cytokines that occurs in IBD results in disease progression and tissue damage and limits the resolution of inflammat...

OBJECTIVE To present psychometric data on youth and parent versions of the Inflammatory Bowel Disease-Family Responsibility Questionnaire (IBD-FRQ), a measure of family involvement in IBD management. METHODS Fifty-eight adolescents with inflammatory bowel disease (IBD), along with 55 mothers and 26 fathers completed the IBD-FRQ, a demographics questionnaire, and a measure of family involvemen...

Inflammatory bowel disease (IBD) is a chronic, debilitating disorder of uncertain and perhaps multiple etiologies. It is believed to be due in part to disregulation of the immune system. Neuroimmune interactions may be involved in induction or maintenance of IBD. In the present study, we examined the potential role of a neurotransmitter, substance P, in a mouse model of IBD. We found that bindi...
