Inflammatory bowel diseases (IBDs) are a heterogeneous group of disorders exhibited by two major phenotypic forms: Crohn's disease and ulcerative colitis. Although the aetiology of IBD is unknown, several factors coming from the adipose tissue and skeletal muscles, such as cytokines, adipokines and myokines, were suggested in the pathogenesis of ulcerative colitis; however, it has not been extensively studied whether voluntary exercise can ameliorate that disorder. We explored the effect of moderate exercise (i...

Ulcerative colitis (UC) is a chronic relapsing and remitting inflammatory bowel disease, with a characteristic leukocytic infiltration of the mucosa. Immunosuppression including anti-TNF-α therapy is a mainstay of treatment for many; however, systemic immunosuppression is not universally effective and is associated with potential side effects. The gut-tropic integrin α4β7, which is expressed on leukocytes, mediates migration from the circulation to the intestinal mucosa. Vedolizumab is a monoclonal antibody which blocks the egress of leukocytes via α4β7, preventing accumulation in the mucosa, and attenuating inflammation without systemic immunosuppression...

BACKGROUND: Prescribing information for tumor necrosis factor alpha (TNFα) inhibitors, a mainstay of treatment for moderate to severe inflammatory bowel disease (IBD), instructs cautious use in those with heart failure (HF). However, the limited data behind these warnings are inconclusive and should be weighed against mounting evidence demonstrating worse cardiac outcomes in active IBD. AIMS: To assess whether TNFα inhibitor use is reduced in patients with IBD and HF by analyzing physician practice and prescription patterns...

BACKGROUND: As the American population is aging, the number of older people with inflammatory bowel disease is increasing. We used clinical data from the Sinai-Helmsley Alliance for Research Excellence (SHARE), a prospective cohort, to examine disease and treatment differences in older adults. METHODS: We performed a cross-sectional study assessing demographics and disease behavior by age at diagnosis with univariate, bivariate, and multivariate analyses. "Older-onset" patients were diagnosed after age 60, "younger-onset" patients were diagnosed before age 60 but are older than 60 years, and the remainder were "young...

Colitis associated cancer (CAC) is the colorectal cancer (CRC) subtype that is associated with bowel disease such as ulcerative colitis (UC). The data on role of NF-κB signaling in development and progression of CAC were derived from preclinical studies, whereas data from human are rare. The aim of this work was to study the contribution of NF-κB pathway during UC and CAC, as well as the immunomodulatory effect of all-trans retinoic acid (AtRA). We analyzed the expression of NOS2, TNF-α, TLR4, and NF-κB, in colonic mucosa...

BACKGROUND AND AIMS: The aim of the study was to evaluate, if the strategy to stop anti-TNF treatment after determination of low trough serum levels and exclusion of inflammation is associated with lower relapse rates. METHODS: Since 2013 we followed an exit strategy in patients treated with anti-TNF treatment for inflammatory bowel disease based on trough serum levels. The relapse rates were observed prospectively, data analysis was performed in a retrospective manner of the collected clinical data...

Ulcerative colitis (UC) is a long-time inflammatory condition arising from aberrant immune activation in the colon and the rectum. Interleukin (IL)-35 plays critical roles in autoimmune disorders. In this study, we explored the pathways of IL-35 in affecting UC. First, peripheral blood mononuclear cells (PBMCs) from UC patients were obtained. Pretreating PBMCs with IL-35 resulted in significantly elevated IL-10 production from whole PBMCs as well as B cells, whereas pretreating PBMCs with IL-12 or IL-27 did not demonstrate a similar effect...

BACKGROUND: Cyclophilin A (CyPA) is an immunomodulatory protein, high expression of which correlates with poor outcome of patients with inflammatory diseases. However, its role in inflammatory bowel disease (IBD) has not been studied. AIM: This study analyzes the correlation between cyclophilin A, matrix metalloproteinase (MMP)-9, and tissue inhibitor of MMP (TIMP)/MMP-9 complexes in the inflamed and non-inflamed colon mucosa of UC and CD patients. METHODS: Serum and biopsy specimens from inflamed and non-inflamed colonic mucosa of 38 patients with IBD (19 with UC and 19 with CD) and 16 controls were included in our study...

BACKGROUND: The recent genome-wide association studies (GWAS) in inflammatory bowel disease (IBD) suggest significant genetic overlap with complex mycobacterial diseases like tuberculosis or leprosy. TLR variants have previously been linked to susceptibility for mycobacterial diseases. Here we investigated the contribution to IBD risk of two TLR2 polymorphisms, the low-prevalence variant Arg753Gln and the GTn microsatellite repeat polymorphism in intron 2. We studied association with disease, possible correlations with phenotype and gene-gene interactions...

The population of older patients with inflammatory bowel disease (IBD) continues to grow, partly reflecting the aging global population in general. The debilitating effects of IBD compound age-related decrements in health and functional capacity, and make the medical management of older patients with Crohn's disease and ulcerative colitis distinctly challenging to clinicians. Here, we review the recent literature describing the pharmacologic management of IBD in this population, with focus on the safety, tolerability, and efficacy of common treatment options, such as steroids, immunomodulators, tumor necrosis factor-α antagonists, and integrin antagonists; surgical interventions in older patients are also discussed...

Ulcerative colitis (UC) is a relapsing-remitting chronic inflammatory disorder affecting the mucosal surface in a continuous manner from the rectum through part of, or the entire, colon. Patients with severe disease and those who become refractory or intolerant to corticosteroids and/or immunosuppressants, require treatment with biologic agents that target tumor necrosis factor-α (TNF). Golimumab, a fully human monoclonal antibody, is the latest TNF antagonist to get approved for the treatment of moderate-to-severe UC...

Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are complex chronic inflammatory conditions of the gastrointestinal tract that are driven by perturbed cytokine pathways. Anti-tumor necrosis factor-α (TNF) antibodies are mainstay therapies for IBD. However, up to 40% of patients are nonresponsive to anti-TNF agents, which makes the identification of alternative therapeutic targets a priority. Here we show that, relative to healthy controls, inflamed intestinal tissues from patients with IBD express high amounts of the cytokine oncostatin M (OSM) and its receptor (OSMR), which correlate closely with histopathological disease severity...

BACKGROUND/AIM: The excessive apoptosis of intestinal epithelial cells (IECs) partly accounts for the development of colonic inflammation and eventually results in ulcerative colitis (UC). Humanin, an endogenous anti-apoptotic peptide, has previously been shown to protect against Alzheimer's disease and a variety of cellular insults. The present study aimed to investigate the effects of glysin variant of humanin (HNG) on 2,4,6-trinitrobenzene sulphonic acid (TNBS)-induced colitis in rats...

Cardiovascular disease (CVD) can arise because of chronic inflammation and inflammatory bowel disease (IBD) is one such disease where the risk for CVD and eventual heart failure is increased considerably. The incidence of IBD, which refers to both ulcerative colitis and Crohn's disease, has been on the increase in several countries and is a potential risk factor for CVD. Although IBD can potentially cause venous thromboembolism, its significance in arterial stiffening, atherosclerosis, ischemic heart disease and myocardial infarction is only being realized now and it is currently under debate...

BACKGROUND: Active inflammatory bowel disease (IBD) during conception and pregnancy may increase the risk of adverse birth outcomes. Former studies have examined heterogeneous groups of women with varying degrees of IBD severity. We aimed to examine the effect of active IBD on birth outcomes in a more homogeneous group of women with a moderate to severe disease course. Since in Denmark, moderate to severe IBD is an indication for use of anti-tumor necrosis factor-α therapy, we examined all women who used anti-tumor necrosis factor therapy during pregnancy...
