Neutrophils participate in the pathogenesis of ulcerative colitis (UC) through regulating the intestinal homeostasis. Several inflammatory diseases are reported to be regulated by proline-rich tyrosine kinase 2B (PTK2B). However, the role of PTK2B in regulating the function of neutrophils and the pathogenesis of UC remains unknown. In this study, the mRNA and protein levels of PTK2B in the colonic tissues from UC patients were measured by using quantitative real-time polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry...

INTRODUCTION: Discordance between gastrointestinal (GI) symptoms and endoscopic inflammation in patients with ulcerative colitis (UC) is known. However, the correlations between symptoms and endoscopic and histologic (endo-histologic) mucosal healing and remains unknown. METHODS: We performed a secondary analysis of prospectively collected clinical, endoscopic, and histologic data on 254 colonoscopies from 179 unique adults at a tertiary referral center from 2014 to 2021...

OBJECTIVE AND DESIGN: Inflammatory bowel disease (IBD) is an idiopathic inflammatory condition of the digestive system marked by oxidative stress, leukocyte infiltration, and elevation of inflammatory mediators. In this study, we demonstrate the protective effect of ethyl gallate (EG), a phytochemical, and propyl gallate (PG), an anti-oxidant, given through normal drinking water (DW) and copper water (CW) in various combinations, which had a positive effect on the amelioration of DSS-induced ulcerative colitis in C57BL/6 J mice...

Inflammatory bowel disease, including Crohn's disease and ulcerative colitis, comprises multiple complex immune-mediated disorders. Early diagnosis and prompt disease control may prevent long-term complications and hospitalization. The therapeutic options have expanded in the last two decades, with the development of biologics and small molecules targeting specific pathways implicated in inflammatory bowel disease pathogenesis. The interleukin (IL)-23/Th-17 axis is one such example. Targeting IL-12/23 is effective for the treatment of both moderate-to-severe Crohn's disease and ulcerative colitis, and ustekinumab (an IL-12/23p40 antagonist) is approved for both indications...

BACKGROUND: The identification of patients at high risk of a disabling disease course would be invaluable in guiding initial therapy in Crohn's disease (CD). Our objective was to evaluate a combination of clinical, serological, and genetic factors to predict complicated disease course in pediatric-onset CD. METHODS: Data for pediatric-onset CD patients, diagnosed before 17 years of age between 1988 and 2004 and followed more than 5 years, were extracted from the population-based EPIMAD registry...

Inflammatory bowel diseases (IBD), which include Crohn's disease and ulcerative colitis, are a rapidly growing public health concern worldwide. These diseases are heterogeneous at the clinical, immunological, molecular, genetic, and microbial level, but characteristically involve a disrupted immune-microbiome axis. Shortcomings in conventional treatment options warrant the need for novel therapeutic strategies to mitigate these life-long and relapsing disorders of the gastrointestinal tract. Polyphenols, a diverse group of phytochemicals, have gained attention as candidate treatments due to their array of biological effects...

Ulcerative colitis (UC) is one of types of inflammatory bowel disease with high recurrence. Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC. Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC. Many Chinese herbal medicines including some of single herb, herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity...

BACKGROUND: Growth factors are essential for maintenance of intestinal health. We previously showed that exogenous neuregulin-4 (NRG4) promotes colonocyte survival during cytokine challenge and is protective against acute models of intestinal inflammation. However, the function(s) of endogenous NRG4 are not well understood. Using NRG4-/- mice, we tested the role of endogenous NRG4 in models of colitis skewed toward either adaptive (interleukin-10 receptor [IL-10R] neutralization) or innate (dextran sulfate sodium [DSS]) immune responses...

PURPOSE OF REVIEW: The chronic inflammatory bowel diseases (IBD), Crohn's disease, and ulcerative colitis, are associated with an increased risk of symptomatic Clostridium difficile infection (CDI). CDI may also masquerade as an IBD flare and complicate IBD management. This review provides a comprehensive overview of the epidemiology, diagnosis, and treatment of CDI in IBD patients. RECENT FINDINGS: CDI remains common in IBD with complications including flares in disease activity, recurrent CDI episodes, and prolonged hospital stays...

PURPOSE OF REVIEW: The management of hospitalized patients with inflammatory bowel disease (IBD) is complex. Despite considerable therapeutic advancements in outpatient ulcerative colitis and Crohn's disease management, the in-hospital management continues to lag with suboptimal outcomes. The purpose of this review is to provide a brief overview of our approach to managing patients hospitalized with acute severe ulcerative colitis (ASUC) and Crohn's disease-related complications, followed by a summary of emerging evidence for new management approaches...

PURPOSE OF REVIEW: Hypoxia is a known contributor to inflammation in inflammatory bowel diseases (IBD), and a growing interest has emerged in pharmacologically targeting hypoxia response pathways to treat IBD. The most basic form of treatment for hypoxia is delivering higher amounts of oxygen to the intestinal mucosa. In this review, we summarize the evidence in support of hyperbaric oxygen therapy (HBOT), a mechanism to deliver high amounts of oxygen to tissue, for treating IBD. RECENT FINDINGS: Two phase 2 clinical trials in hospitalized ulcerative colitis patients suffering from moderate-to-severe flares have demonstrated that HBOT improves responsiveness to steroids and avoidance of rescue medical and surgical therapy...

Inflammatory bowel disease (IBD) is a special chronic intestinal inflammatory disease, which is mainly divided into Crohn's disease (CD) and ulcerative colitis (UC). Its occurrence is a complex process that regulated by multiple signaling pathways, including nuclear factor erythroid 2-related factor (Nrf2)/ antioxidant response element (ARE) signaling pathway. Nrf2/ARE pathway as the central defense mechanism against oxidative stress controls the expression of many antioxidant and anti-inflammatory genes in the nucleus, and plays a crucial role in the treatment of IBD...

INTRODUCTION: Epidemiological studies indicated that inflammatory bowel disease (IBD), with Crohn's disease and ulcerative colitis as its two main types, is associated with dementia. However, little is known about how adolescents with IBD will affect their cognitive ability as adults. The hippocampus, which is crucial for memory and adult neurogenesis, is closely associated with modulation of cognitive processes. Using a low kDa dextran sulfate sodium (DSS, 5 kDa)-induced chronic colitis (mild chronic colitis) mice model in adolescent mice, we investigated the effects of mild chronic colitis on cognitive functions and hippocampal neurogenesis from adolescent mice to adult mice...
