BACKGROUND Activated Cdc42 kinase1 (ACK1) is a non-receptor tyrosine kinase which is critical for cell survival, proliferation, and migration. Genomic amplification of ACK1 has been reported in multiple human cancers. We aimed to investigate ACK1 protein expression in colorectal mucosa with inflammation and neoplasm, and to evaluate its correlation with disease activity and severity. MATERIAL AND METHODS A total of 250 individuals who underwent total colonoscopy were collected randomly from January 2007 to May 2013 in Nanfang Hospital, Guangzhou, China...

BACKGROUND: Venous thromboembolism after abdominal surgery occurs in 2% to 3% of patients with Crohn's disease and ulcerative colitis. However, no evidence-based guidelines currently exist to guide postdischarge prophylactic anticoagulation. OBJECTIVE: We sought to determine the use of postoperative postdischarge venous thromboembolism chemical prophylaxis, 90-day venous thromboembolism rates, and factors associated with 90-day thromboembolic events in IBD patients following abdominal surgery...

Combination therapy is an emerging strategy that is under intensive preclinical investigation for the treatment of various diseases. CD98 is highly overexpressed on the surfaces of epithelial cells and macrophages in the colon tissue with ulcerative colitis (UC), which is usually associated with mucosal damage and inflammation. We previously proved that CD98 siRNA (siCD98)-induced down-regulation of CD98 in colitis tissue decreased the severity of UC to a certain extent. In an effort to further improve the therapeutic efficacy, we aim to simultaneously deliver siCD98 in combination with a potent anti-inflammatory agent, curcumin (CUR), using hyaluronic acid (HA)-functionalized polymeric nanoparticles (NPs)...

A 34-year-old female with left-sided ulcerative colitis (UC) developed severe febrile neutropenia/thrombocytopenia soon after infliximab induction therapy. There was no other plausible cause of the cell line abnormalities other than an accurate temporal association with infliximab administration. Supportive care, broad-spectrum antibiotic, and single dose of filgrastim was given on day 5 of admission due to persistently low absolute neutrophil count and fevers. The cell lines recovered, fever resolved and the patient made a complete clinical recovery...

There are very few reports of elevated lipase in pediatric inflammatory bowel disease (IBD). Symptoms of pancreatitis may be masked by abdominal pain in pediatric IBD. During the initial presentation of IBD in our patient, lipase was elevated to more than 3 times the upper limit of normal. Normalization of values coincided with remission of IBD. This may be due to extraintestinal involvement of the pancreas as part of the inflammatory process or due to leakage of pancreatic enzymes from an inflamed gut or mediated by inflammatory cytokines...

Melatonin is produced in the pineal gland as well as many other organs, including the enterochromaffin cells of the digestive mucosa. Melatonin is a powerful antioxidant that resists oxidative stress due to its capacity to directly scavenge reactive species, to modulate the antioxidant defense system by increasing the activities of antioxidant enzymes, and to stimulate the innate immune response through its direct and indirect actions. In addition, the dysregulation of the circadian system is observed to be related with alterations in colonic motility and cell disruptions due to the modifications of clock genes expression...

BACKGROUND: Recent immunologic data implicates involvement of mucosal immune cells of the intestine like eosinophils and mast cells to be functionally involved in the pathogenesis of UC. Mast cell activation is followed by increased secretion and elevated tissue concentration of histamine. Inhibition of mucosal histamine release in colon may be an effective therapeutic approach to treat UC. Some studies report that intestinal inflammation associated with acute and chronic colitis has been ameliorated by fexofenadine in mice...

The United States spends a greater share per gross domestic product on health care than any other developed country in the world. Cost-conscious, high-value care has an important role in the practice of medicine. Inflammatory bowel disease (IBD) affects 1.6 million people in the United States and is responsible for significant health care costs, with estimates as high as $31.6 billion annually, a large portion of which is attributable to the use of biologic therapies. As the number of therapeutic targets for IBD expands, gastroenterologists can anticipate the arrival of novel therapeutic agents on the market, and these may carry significant costs...

The incidence of inflammatory bowel disease (IBD) and associated oxidative stress is increasing. The antioxidant mineral selenium (Se) was measured in serum samples from 106 IBD patients (53 with ulcerative colitis (UC) and 53 with Crohn's disease (CD)) and from 30 healthy controls. Serum Se concentrations were significantly lower in UC and CD patients than in healthy controls (p < 0.001) and significantly lower in CD patients than in UC patients (p = 0.006). Se concentrations in patients were significantly influenced by sex, body mass index (BMI), the inflammatory biomarker α-1-antitrypsin, surgery, medical treatment, the severity, extent, and form of the disease and the length of time since onset (p < 0...

BACKGROUND & AIMS: Little is known about outcomes of patients with ulcerative colitis with low-grade dysplasia (UC-LGD). We estimated the incidence of and risk factors for progression to colorectal cancer (CRC) in cohorts of patients with UC-LGD who underwent surveillance (surveillance cohort), and the prevalence of dysplasia-related findings among patients who underwent colectomy for UC-LGD (surgical cohort). METHODS: We performed a systematic literature review through June 1, 2016 to identify cohort studies of adults with UC-LGD...

BACKGROUND: Pyoderma gangrenosum (PG) is an uncommon, ulcerative, cutaneous condition, often caused by surgical trauma that can masquerade as a pyogenic disease process requiring debridement and antibiotics. Treatment is, however, medical, with delay leading to significant morbidity. In addition, medical workup for coincident disorders has been suggested. The purpose of this study was to test the hypothesis that pediatric PG has differing disease associations and therefore requires a differing medical workup...

It is well accepted that inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is one of high risk factors for colorectal cancer (CRC). This supports the notion that inflammation plays a key role in cancer development. Epidemiologic studies have shown that vitamin D (Vit D) deficiency is associated with IBD and various types of cancer including colorectal cancer. Clinical trials and mouse models have shown that Vit D is beneficial in preventing or ameliorating inflammation and carcinogenesis...

Ulcerative colitis is a chronic inflammatory disease affecting the colon, and its incidence is rising worldwide. The pathogenesis is multifactorial, involving genetic predisposition, epithelial barrier defects, dysregulated immune responses, and environmental factors. Patients with ulcerative colitis have mucosal inflammation starting in the rectum that can extend continuously to proximal segments of the colon. Ulcerative colitis usually presents with bloody diarrhoea and is diagnosed by colonoscopy and histological findings...

Ulcerative colitis and Crohn's disease are the major forms of inflammatory bowel disease. Cytokines of the tumor necrosis factor (TNF) family play an important role in the regulation of intestinal inflammation. In this review, we discuss the function of key cytokines of this family - TNF and lymphotoxin (LT) - in mucosal healing, IgA production, and in control of innate lymphoid cells (ILCs), novel regulators of mucosal homeostasis in the gut. TNF plays a central role in the pathogenesis of inflammatory bowel diseases (IBD)...

The active vitamin D metabolite 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3) has important regulatory actions in the gut through endocrine and probably also intracrine, autocrine and paracrine mechanisms. By activating the vitamin D receptor (VDR), which is expressed at a high level in the small intestine and colon, 1,25(OH)2D3 regulates numerous genes that control gut physiology and homeostasis. 1,25(OH)2D3 is a major responsible for epithelial barrier function and calcium and phosphate absorption, and the host's defense against pathogens and the inflammatory response by several types of secretory and immune cells...
