We report the first study to evaluate the intestinal mucosal microbiota of dogs with inflammatory bowel disease (IBD) and dogs with food-responsive diarrhea (FRD) before and after treatment. It was hypothesized that differences in the microbial composition exist between both disease groups and within groups pre- vs. post-treatment. Duodenal and colonic biopsies were obtained endoscopically from 24 dogs (15 FRD, 9 IBD) before and after treatment. The intestinal microbiota was evaluated by Illumina sequencing of the bacterial 16S rRNA gene...

Background and aims: Conventional follow-up of teenagers with inflammatory bowel diseases (IBD) is done during scheduled outpatient visits regardless of how well the patient feels. We designed a telemonitoring strategy for early recognition of flares and compared its efficacy with conventional follow-up. Methods: Multicentre randomised trial in patients aged 10-19 years with IBD in clinical remission at baseline. Participants assigned to telemonitoring received automated alerts to complete a symptom score and send a stool sample for calprotectin measurement...

Recent studies show that colonic vitamin D receptor (VDR) signaling protects the mucosal epithelial barrier and suppresses colonic inflammation, but the underlying molecular mechanism remains to be fully understood. To investigate the implication of colonic VDR down-regulation seen in patients with inflammatory bowel disease, we assessed the effect of gut epithelial VDR deletion on colonic inflammatory responses in an experimental colitis model. In 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis model, mice carrying VDR deletion in gut epithelial cells (VDRf/f;Villin-Cre or VDRΔIEC) or in colonic epithelial cells (VDRf/f;CDX2-Cre or VDRΔCEC) developed more severe clinical colitis than VDRf/f control mice, characterized by more robust TH1 and TH17 responses, with greater increases in mucosal IFN-γ+, IL-17+ and IFN-γ+IL-17+ T cells...

Inflammatory bowel disease (IBD) causes inflammation to the gastrointestinal tract. Local administration of Anti-inflammatory drugs such as 5-aminosalysilic acid (5-ASA) can alleviate the symptoms of IBD. The application of nanoparticles for IBD treatment in direct rectal administration showed high drug availability and treatment efficacy. However, relying on size-dependent adsorption of smaller particles is not sufficient for making the formulation capable of targeting. Intestinal organoids can improve the functionality of the nanoparticles due to their ability to adsorb small nanoparticle inside the lumen and attach to the damaged area...

BACKGROUND: Faecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection. In short-term the treatment has been shown to be safe, however, there are no large, long-term follow-up studies looking into the potential adverse effects. AIM: To analyse the long-term effect of FMT treatment in patients with recurrent C. difficile infection and to compare the outcome to antibiotic treated patients. METHODS: Altogether 84 patients of which 45 received a FMT treatment and 39 served as controls receiving antibiotics for the infection were followed on average for 3...

The goal of this study was explore the role of indoleamine 2, 3-dioxygenase (IDO) in the therapeutic effect of probiotics on inflammatory bowel disease (IBD). Trinitro-benzene sulfonic acid (TNBS) was used to induce colitis in mice, and 1-methyltryptophan (1-MT) was used to block the expression of IDO. Clinical manifes-tations, macroscopic and microscopic colonic alterations were assessed using the dis-ease activity index (DAI), Wallace-Keenan, and Curtner scoring systems, respectively. The expression of colonic IDO was detected by western blot...

Inflammatory bowel disease (IBD) is an inflammatory disease of unclear etiopathogenesis and challenging diagnosis, frequently complicated by anemia and malnutrition. C-reactive protein (CRP) remains the only biochemical marker of clinical relevance. The aim of this study was to test hypothesis that transferrin, coinfluenced by inflammation, malnutrition, anemia, and oxidative stress, may better reflect global IBD patient's condition than any other more specific index. Transferrin and other indices of inflammation, anemia, malnutrition, and oxidative stress were measured in 137 IBD patients (Crohn's disease (CD): n = 63 and ulcerative colitis (UC): n = 74) and 97 controls...

Amir Houshang Mohammad Alizadeh
Cholangitis is a serious life-threatening situation affecting the hepatobiliary system. This review provides an update regarding the clinical and pathological features of various forms of cholangitis. A comprehensive search was performed in the PubMed, Scopus, and Web of Knowledge databases. It was found that the etiology and pathogenesis of cholangitis are heterogeneous. Cholangitis can be categorized as primary sclerosing (PSC), secondary (acute) cholangitis, and a recently characterized form, known as IgG4-associated cholangitis (IAC)...

Inflammatory bowel diseases (IBD) are chronic inflammatory diseases involving all or part of the gastrointestinal tract. The stress-activated serine-threonine protein kinase D1 (PKD1) protein has previously been implicated in intestinal immune regulation. The objective of this study was to evaluate the effects of human PKD1 in relation to intestinal inflammation, using a co-culture model of intestinal epithelial Caco-2 cells and RAW264.7 macrophages. An inflammatory response was induced in the macrophages by lipopolysaccharide (LPS), upregulating the expression of tumour necrosis factor alpha (TNF-α), interleukin- (IL-) 1β, and IL-6 besides increasing the secretion of TNF-α protein...

Background: An unmet need remains for safe and effective treatments to induce and maintain remission in inflammatory bowel disease (IBD) patients. The Janus kinase (JAK) inhibitor, tofacitinib, has demonstrated robust efficacy in ulcerative colitis patients although, like other systemic immunosuppressants, there may be safety concerns associated with its use. This preclinical study evaluated whether modulating intestinal inflammation via local JAK inhibition can provide efficacy without systemic immunosuppression...

Anti-tumour necrosis factor (TNF) agents have demonstrated efficacy in inflammatory bowel disease (IBD). Cutaneous reactions such as new onset psoriasis or psoriasiform-like reactions are among the most common adverse reactions. We retrospectively identified cases of anti-TNF-induced psoriasis or psoriasiform manifestations in IBD patients at a tertiary centre in Australia. A total of 10 (six females) of 270 (3.7%) IBD patients treated with anti-TNF therapy developed drug-induced psoriatic or psoriasiform-like reactions: five patients were treated with infliximab and five with adalimumab; nine had Crohn disease...

Increased understanding of the immunopathology of inflammatory bowel disease (IBD) has led to the development of targeted therapies and has unlocked a new era in IBD treatment. The development of treatment options aimed at a variety of pathological mechanisms offers new hope for customized therapies. Beyond anti-tumor necrosis factor agents, selective lymphocyte trafficking inhibitors have been proposed as potent drugs for IBD. Among these, vedolizumab has recently been approved for both Crohn's disease and ulcerative colitis...

Acute pancreatitis is a well-recognised complication of endoscopic procedures like endoscopic retrograde cholangiopancreatography but not oesophagogastroduodenoscopy (OGD). I report a case of a 33-year-old woman, admitted with severe epigastric pain and vomiting 2 hours after an elective OGD for evaluation of chronic gastrointestinal symptoms. Pancreatitis was diagnosed on the basis of elevated lipase (40 790 U/L; normal 11-82) and findings on imaging studies. Other common causes of acute pancreatitis such as gallstones, alcohol and medications were ruled out...

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic gastrointestinal condition affecting over 5 million people globally and 1.6 million in the United States but currently lacks a precisely determined cause or cure. The range of symptoms IBD patients experience are often debilitating, and the societal stigmas associated with some such symptoms can further degrade their quality of life. Better understanding the nature of this public reproach then is a critical component for improving awareness campaigns and, ultimately, the experiences of IBD patients...
