Biological agents are frequently used in the management of inflammatory bowel disease, and it is important to understand the potential adverse effects of these therapies. Ustekinumab is a human monoclonal antibody that interferes with interleukin-12 and -23 cytokine signaling and is approved for the treatment of moderate to severe Crohn's disease. We report 2 cases of neurological adverse events, one of which is consistent with posterior reversible encephalopathy syndrome (PRES), in the setting of ustekinumab therapy for Crohn's disease...

Renal and urinary involvement has been reported to occur in 4% to 23% of inflammatory bowel disease (IBD) patients. Parenchymal renal disease is rare and most commonly affects glomerular and tubulointerstitial compartments. The most common findings on renal biopsy of IBD patients are IgA nephropathy and tubulointerstitial nephritis. Overall morbidity of IBD-related renal manifestations is significant, and there is often only a short window of injury reversibility. This, along with subtle clinical presentation, requires a high index of suspicion and routine monitoring of renal function...

Intestinal ischemia/reperfusion (I/R)-induced systemic inflammation leads to multiple organ dysfunction syndrome (MODS). Previous studies have indicated that the NLRP3 inflammasome modulates intestinal inflammation; however, the pathophysiological mechanisms remain unclear. Autophagy is a critical metabolic mechanism that promotes cellular survival following ischemic injury. Recently, basal autophagy has been implicated in the alleviation of extensive inflammation. However, the role of autophagy in NLRP3 inflammasome activation in intestinal I/R-induced inflammatory injury remains undefined...

Anti-microbial signaling pathways are normally triggered by innate immune receptors when detecting pathogenic microbes to provide protective immunity. Here we show that the inflammasome sensor Nlrp1 aggravates DSS-induced experimental mouse colitis by limiting beneficial, butyrate-producing Clostridiales in the gut. The colitis-protective effects of Nlrp1 deficiency are thus reversed by vancomycin treatment, but recapitulated with butyrate supplementation in wild-type mice. Moreover, an activating mutation in Nlrp1a increases IL-18 and IFNγ production, and decreases colonic butyrate to exacerbate colitis...

Lymph node metastasis is the most important prognostic characteristic of colorectal cancer. Carcinoembryonic antigen messenger RNA was shown to detect tumor cells that have disseminated to lymph nodes of colorectal cancer patients and to be at least as good as the hematoxylin and eosin method to predict survival in colorectal cancer patients. CXCL17 was recently shown to be ectopically expressed in colon cancer tumors. Therefore, CXCL17 may serve as prognostic marker alone or in combination with carcinoembryonic antigen...

SCOPE: Inflammatory bowel disease (IBD) is a chronic disease of gastrointestinal tract in which oxidative stress and overactivation of inflammatory response are implicated. The aim of the present study was to test the hypothesis that hydroxyproline (Hyp), an amino acid with an antioxidative property, attenuates DSS-induced colitis in mice. METHODS AND RESULTS: Male C57BL/6 supplemented with or without 1% Hyp were subjected to 2.5% DSS to induce colitis. Hyp attenuated the severity of colitis as evidenced by reduced disease activity index scores, decreased myeloperoxidase activity, histological damage, and apoptosis...

OBJECTIVE: Ulcerative colitis (UC) is an unexplained inflammatory disease in bowel. Some studies reported that microRNA-19b (miR-19b) was closely related to cell inflammatory response. We aimed to explore the molecular mechanism of miR-19b on lipopolysaccharide (LPS)-induced human intestinal cell inflammatory injury. MATERIALS AND METHODS: Caco2 cells were treated with 10 ng/ml LPS to induce inflammatory injury. The expression of miR-19b and runt-related transcription factor 3 (Runx3) was changed in Caco2 cells by cell transfection...

Fibrosis is known to be the hallmarks of chronic inflammation of the bowel. Epithelial damage due to inflammation compromises the barrier function of the gastrointestinal tract. This barrier dysfunction leads to further spread of inflammation resulting in a chronic state of inflammation. This chronic inflammation leads to development of fibrosis, which has very limited therapeutic options and usually requires surgical removal of the affected tissue. Our previous work has shown that Caffeic acid phenethyl ester (CAPE) is a naturally occurring anti-inflammatory agent, found in propolis, has been found to be protective in experimental colitis via enhancement of epithelial barrier function...

BACKGROUND/AIMS: Retinoid-related orphan receptor gamma t (RORγt) is a master regulator of T helper 17 cells that plays a pivotal role in the production of inflammatory cytokines including interleukin (IL)-17. Therefore, RORγt has attracted much attention as a target receptor for the treatment of inflammatory diseases including rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, and psoriasis. This study aims to characterize TAK-828F, a potent and selective RORγt inverse agonist...

Inflammatory bowel disease (IBD) is a multifactorial inflammatory disease, and increasing evidence has demonstrated that the mechanism of the pathogenesis of IBD is associated with intestinal epithelial barrier injury. Long non‑coding RNAs (lncRNAs) are a class of transcripts >200 nucleotides in length with limited protein‑coding capability. Nuclear paraspeckle assembly transcript 1 (NEAT1) is a recently identified nuclear‑restricted lncRNA, which localizes in subnuclear structures, termed paraspeckles, and is involved in the immune response in a variety of ways...

Acute mesenteric ischaemia (AMI) is an uncommon cause of acute hospital admission with high mortality rates (50-90%) that requires early diagnosis and treatment. With the increase in average life expectancy, AMI represents one of the most threatening abdominal conditions in elderly patients. Untreated, AMI will cause mesenteric infarction, intestinal necrosis, an overwhelming inflammatory response and death. Early intervention can reverse this process leading to a full recovery, but the diagnosis of AMI is difficult...

Flaxseed is high in omega-3 polyunsaturated fatty acids, fiber and lignans known to lower cholesterol levels. However, its use for prevention or treatment of inflammatory bowel diseases has yielded mixed results, perhaps related to dietary interactions. In this study, we evaluated the impact of ground flaxseed supplementation on the severity of Citrobacter rodentium-induced colitis in the setting of either a high fat (HF; ~36 %kcal) or reduced fat (RF; ~12 %kcal) diet. After weaning, C57BL/6 mice (n=8-15/treatment) were fed ground flaxseed (7g/100g diet) with either HF (HF Flx) or RF (RF Flx) diets for four weeks prior to infection with C...

BACKGROUND: Diversion colitis (DC) is characterized by nonspecific inflammation in the remaining colon or rectum, and loss of the fecal stream plays a major role in the disease's development. Although the majority of patients are asymptomatic, medical and/or surgical treatment is required for those who are symptomatic. There is a particular interest on how to manage patients with acute and severe clinical presentations, but the pathogenesis is not fully understood. We report the rare case of a man with acute and severe DC mimicking ulcerative colitis (UC) with extra-intestinal manifestations that was successfully managed with surgical treatment...

The introduction of biological agents has revolutionized the management of ulcerative colitis (UC). Biosimilars are considered to be equivalent to the reference biologic products in terms of pharmacokinetic properties, clinical effectiveness and safety and have now been approved in inflammatory bowel diseases (IBD). CT-P13 was the first biosimilar to infliximab that obtained regulatory approval by the EMA and US FDA. Accumulating data on biosimilars led to an increased acceptance amongst practicing gastroenterologists and their use can be associated with a potential reduction in healthcare costs...

RIPK1 (receptor-interacting serine/threonine kinase 1) is a master regulator of signaling pathways leading to inflammation and cell death and is of medical interest as a drug target. We report four patients from three unrelated families with complete RIPK1 deficiency caused by rare homozygous mutations. The patients suffered from recurrent infections, early-onset inflammatory bowel disease, and progressive polyarthritis. They had immunodeficiency with lymphopenia and altered production of various cytokines revealed by whole-blood assays...

Receptor-interacting protein kinase 3 (RIPK3) is essential for mucosal repair in inflammatory bowel diseases (IBD) and colorectal cancer. However, its role in tumor immunity is unknown. Here, we report that decreased RIPK3 in colorectal cancer correlates with the accumulation of myeloid-derived suppressor cells (MDSC). Deficiency of RIPK3 boosted tumorigenesis via accumulation and immunosuppressive activity of MDSCs. Reduction of RIPK3 in MDSC and colorectal cancer cells elicited NFκB-transcribed COX-2, which catalyzed the synthesis of prostaglandin E2 (PGE2 )...
