Background: Clostridium difficile is a leading cause of nosocomial infection. The role of cytokine IL-27 in the immunopathology of Clostridium difficile infection (CDI) remains unknown. Methods: The production of IL-27 was determined in human and murine CDI. Furthermore, wild-type (WT) and IL-27 receptor-deficient (WSX-1 -/-) mice were treated with an antibiotic mixture and infected with C.difficile to investigate the effects of IL-27 on host response to CDI. Results: IL-27 production was elevated during CDI in humans and mice...

BACKGROUND: Patients with inflammatory bowel disease are at an increased risk of Clostridium difficile infection (CDI), but the impact of CDI on disease severity is unclear. The aim of this study was to determine the effect of CDI on long-term disease outcome in a matched cohort of patients with inflammatory bowel disease. METHODS: Patients who tested positive for infection formed the CDI-positive group. We generated a 1:2 propensity matched case to control cohort based on risk factors for CDI in the year before infection...

BACKGROUND: Interestingly, Clostridium difficile infection (CDI) worsens the course of inflammatory bowel disease (IBD); however, there is a paucity of data regarding the treatment of CDI in this group of patients. METHODS: This was a prospective, single-blind trial. Children with flare of IBD and CDI were randomly assigned to receive metronidazole or rifaximin orally for 14 days. CDI was diagnosed based on a positive well-type enzyme immunoassay (EIA) toxins A/B stool test for C...

- As yet, with cure rates around 85%, recurrent Clostridium difficile infection is the only definite indication for faecal microbiota transplantation.- Faecal microbiota transplantation induces clinical remission and endoscopic improvements in 24-30% of patients with ulcerative colitis, compared to 5% (water) to 20% (autologous faeces) in placebo-treated patients. Current research focuses on the identification of 'super donors', and subgroups of patients in which faecal microbiota transplantation is effective...

BACKGROUND & OBJECTIVES: Clostridium difficile is the primary cause of hospital-acquired colitis in patients receiving antibiotics. The pathogenicity of the organism is mainly due to the production of toxins. This study was conducted to investigate the presence of toxigenic C. difficile in the faecal samples of hospitalized patients suspected to have C. difficile infection (CDI) and corroborating the findings with their clinical and demographic data. METHODS: Diarrhoeic samples obtained from 1110 hospitalized patients were cultured for C...

Objective:Clostridium difficile causes diarrhea and colitis by releasing toxin A and toxin B. In the human colon, both toxins cause intestinal inflammation and stimulate TNFα expression via activation of NF-κB. It is well established that the macrolide antibiotic fidaxomicin is associated with reduced relapses of C. difficile infection. We showed that fidaxomicin and its primary metabolite, OP-1118, significantly inhibited toxin A-mediated intestinal inflammation in mice in vivo and toxin A-induced cell rounding in vitro We aim to determine whether fidaxomicin and OP-1118 possess anti-inflammatory effects against toxin A and toxin B in the human colon and examine the mechanism of this response...

BACKGROUND & AIMS: Clostridium difficile infection (CDI) causes flares in patients with inflammatory bowel disease (IBD). We investigated the frequency and outcomes of non-CDI bacterial enteric infections in symptomatic patients with IBD. METHODS: We performed a retrospective study of patients with ulcerative colitis (UC) or Crohn's disease (CD) from whom stool samples were collected and analyzed by PCR or culture for bacterial pathogens (Campylobacter jejuni or C coli, Salmonella species, Shigella species, entero-invasive Escherichia coli, shiga toxin-producing E coli, or Yersinia species) from November 19, 2011, through June 30, 2014...

BACKGROUND/AIMS: Clostridium difficile infection (CDI) frequently complicates ulcerative colitis (UC) and can mimic disease flare. Differentiating UC flare from CDI remains a clinical challenge, particularly due to C. difficile colonization. Procalcitonin (PCT) is a serum biomarker for bacterial infections. We hypothesized that PCT would differentiate acute CDI from UC flare and C. difficile colonization. METHODS: A single-center prospective cohort study was conducted from 2013 to 2016...

Most pathogenic Clostridium difficile produce two major exotoxins TcdA and TcdB, in the absence of which the bacterium is non-pathogenic. While it is important to investigate the role of each toxin in the pathogenesis of C. difficile infection (CDI) using isogenic strains, it is impossible to precisely control the expression levels of individual toxins and exclude bacterial factors that may contribute to the toxins' effects during infection. In this study, we utilized an acute intestinal disease model by injecting purified toxins directly into mouse cecum after a midline laparotomy...

INTRODUCTION: Clostridium difficile is a Gram-positive spore-bearing anaerobic bacillus increasingly associated with both community- and hospital-acquired colitis and diarrhea. It is the most common identifiable bacterial cause of healthcare-associated diarrhea associated with antibiotic use and one of the most common anaerobic infections. The diagnosis of C. difficile infection includes detection of toxin A/B in stool specimens by direct enzyme immunoassay, culture of pathogen from the stool specimens using a selective agar Cycloserine-Cefoxitin fructose agar (CCFA), tissue culture assay, and detection of glutamate dehydrogenase an enzyme produced by C...

Many reports have shown that crude extracts of the American cockroach have therapeutic effects on inflammation. In a previous study, our research group showed that an antimicrobial peptide (Periplanetasin-2) derived from the American cockroach via de novo transcriptome analysis inhibited apoptosis of human colonocytes and inflammatory responses of the mouse gut caused by Clostridium difficile toxin A. Here, we examined whether Periplanetasin-4 (Peri-4), another antimicrobial peptide identified via de novo transcriptome analysis of the American cockroach, could also inhibit the various toxicities induced by C...

Fecal microbiota transplantation (FMT) has changed the standard of care for Clostridium difficile infection. However, there is limited data focusing on efficacy and safety profile of FMT in patients with C. difficile infection with underlying inflammatory bowel disease (IBD), including the risk of IBD flare. Recently, there is also emerging evidence supporting the role of FMT to treat IBD including promising randomized trials in ulcerative colitis. However, with heterogeneity across these studies, the clinical application of this emerging therapy has yet to be fully elucidated...

Diseases causing hematochezia range from benign to potentially life-threatening. Systematic pediatric data on the causes of hematochezia are scarce. We studied the underlying causes and long-term outcome of hematochezia in children. We further investigated the relevance of antibiotic-associated hemorrhagic colitis in children, especially if caused by Klebsiella oxytoca.Infants, children, and adolescents with hematochezia were recruited prospectively. Patients were grouped according to age (<1 year, 1-5 years, 6-13 years, >14 years)...

Clostridium difficile is a leading cause of nosocomial infections, causing disease that ranges from mild diarrhea to potentially fatal colitis. A variety of surface proteins, including flagella, enable C. difficile colonization of the intestine. Once in the intestine, toxigenic C. difficile secretes two glucosylating toxins, TcdA and TcdB, which elicit inflammation and diarrheal disease symptoms. Regulation of colonization factors and TcdA and TcdB is an intense area of research in C. difficile biology. A recent publication from our group describes a novel regulatory mechanism that mediates the ON/OFF expression of co-regulated virulence factors of C...
