Clostridium difficile infection (CDI) is facilitated by alteration of the microbiome following antibiotic administration. Antimicrobial therapy directed against the pathogen can treat CDI. Unfortunately, ∼20% of successfully treated patients will suffer recurrence. Bezlotoxumab, a human monoclonal antibody, binds to C. difficile toxin B (TcdB), reducing recurrence presumably by limiting epithelial damage and facilitating microbiome recovery.

We compared the frequency of gastrointestinal (GI) pathogen detection in an oncology patient population by two multiplexed molecular assays, the Luminex xTAG® Gastrointestinal Pathogen Panel (GPP, which identifies 14 GI pathogens) and the BioFire Gastrointestinal Panel (BFGP, which identifies 22 GI pathogens). We additionally reviewed the clinical characteristics of patients tested with both panels. A total of 200 prospectively collected and 81 archived stool samples were tested by both panels. In the prospective cohort, the GPP and BFGP identified a pathogen in 33...

BACKGROUND: Half of patients with inflammatory bowel disease (IBD) require hospitalization. We sought to characterize inpatient quality indicators of care and outcomes during IBD-related hospitalizations at 4 major IBD referral centers in Canada. METHODS: We conducted a multicenter retrospective cohort study of patients with IBD admitted from 2011 to 2013 to tertiary centers in Toronto, Montreal, Ottawa, and Vancouver. We assessed the following inpatient indicators of care: pharmacological venous thromboembolism (VTE) prophylaxis, Clostridium difficile testing, and medical rescue therapy for steroid-refractory ulcerative colitis (UC)...

The microbiome is increasingly recognized as an important influence on human health and many of the comorbidities that affect patients after solid organ transplantation (SOT) have been shown to involve changes in gut bacterial populations. Thus, microbiome changes in an individual patient may have important health implications after SOT but this area remains understudied. We describe changes in the composition of the fecal microbiome from a pediatric heart transplant recipient before and >2.5 years after he underwent repeated fecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection (CDI)...

Clostridium difficile is the cause of the nosocomial C. difficile infection (CDI). The conventional antibiotics used in CDI therapy are often unsuccessful, and recurrent infections may occur. Biofilm formation by C. difficile is associated with chronic or recurrent infections; biofilms may contribute to virulence and impaired antimicrobial efficacy. Manuka honey, derived from the Manuka tree (Leptospermum scoparium), is known to exhibit antimicrobial properties that are associated with its significant content of methylglyoxal, a natural antibiotic...

We report two cases of bacteremia due to Clostridium difficile from two French hospitals. The first patient with previously diagnosed rectal carcinoma underwent courses of chemotherapy, and antimicrobial treatment, and survived the C. difficile bacteremia. The second patient with colon perforation and newly diagnosed lung cancer underwent antimicrobial treatment in an ICU but died shortly after the episode of C. difficile bacteremia. A review of the literature allowed the identification of 137 cases of bacteremia between July 1962 and November 2016...

Clostridium difficile is a bacterial infection that colonises the gut in susceptible hosts. It is associated with exposure to healthcare settings and antibiotic use. It could be assumed that cystic fibrosis (CF) patients are a high-risk group for C.difficile. However, despite high carriage rates, CF patients have low rates of active disease. There are guidelines for the treatment of C.difficile, however little is published specific to treating C.difficile in CF. This article provides an overview of the current management strategies for C...

BACKGROUND: Abnormal permeability and extensive epithelial injury are characteristic of colon wall damage complicating critical illness, such as sepsis, and associated with mortality. To assess mechanisms of such colon epithelial disruption, we studied expression of markers of innate immunity and intercellular junctions in patients with critical illness. METHODS: Emergency colectomy samples from 38 intensive care unit patients with sepsis, fulminant C. difficile colitis, or colon ischemia were studied...

Oral antibiotics such as metronidazole, vancomycin and fidaxomicin are therapies of choice for CDI. Several important mechanisms for C. difficile antibiotic resistance have been described; these include the acquisition of antibiotic resistance genes via transfer of mobile genetic elements, selective pressure in vivo resulting in gene mutations, altered expression of redox-active proteins, iron metabolism and DNA repair, as well as biofilm formation. This update summarizes new information published since 2010 on phenotypic and genotypic resistance mechanisms in C...

Standard antibiotic-based strategies for the treatment of Clostridium difficile infections disrupt indigenous microbiota and commonly fail to eradicate bacterial spores, two key factors that allow recurrence of infection. As an alternative approach to controlling C. difficile infection, a series of bile acid derivatives have been prepared that inhibit taurocholate-induced spore germination. These analogues have been evaluated in a highly virulent NAP1 strain using optical density and phase-contrast microscopy assays...

BACKGROUND: Clostridium difficile is an important cause of infectious colitis among hospitalized patients across the globe. The pathogenic potential of C. difficile in producing significant morbidity and mortality is mainly due to production of toxins A and B. The outbreaks of C. difficile infection (CDI) are due to changes in the genetic sequences of the organism. There is hardly any molecular study reported on the prevalent types of C. difficile strains in India. Toxinotyping and sequencing of locally circulating C...

PURPOSE: Clinical symptoms associated with Clostridium difficile infection (CDI) can vary widely. Carrier state without apparent symptoms is relatively common during infancy. The objective of this study was to determine the association of C. difficile colonization with bowel habit change and the effect of C. difficile colonization treatment on restoration of normal bowel habit. METHODS: Between 2006 and 2014, infants at 1 to 12 months of age with diarrhea for more than 2 weeks who did not improve with conservative care were recruited from Gachon University Gil Medical Center...

Clostridium difficile is frequently found in meat and meat products. Germination efficiency, defined as colony formation, was previously investigated at temperatures found in meat handling and processing for spores of strain M120 (animal isolate), R20291 (human isolate), and DK1 (beef isolate). In this study, germination efficiency of these spore strains was assessed in phosphate buffered saline (PBS, aw ∼1.00), commercial beef jerky (aw ∼0.82/0.72), and aw-adjusted PBS (aw ∼0.82/0.72). Surface hydrophobicity was followed for spores stored in PBS...

BACKGROUND: Antibiotic overuse has promoted growing rates of antimicrobial resistance and secondary antibiotic-associated infections such as Clostridium difficile (C. difficile). Antimicrobial stewardship programs (ASPs) are effective in reducing antimicrobial use in the inpatient setting; however, the unique environment of the emergency department (ED) lends itself to challenges for successful implementation. Front-line ownership (FLO) methodology has been shown to be a potentially effective strategy for the implementation of inpatient ASPs through an iterative multi-pronged approach driven by front-line providers...

The prevalence of colonization with toxigenic Clostridium difficile among patients with hematological malignancies and/or bone marrow transplant at admission to a 566-bed academic medical care center was 9.3%, and 13.3% of colonized patients developed symptomatic disease during hospitalization. This population may benefit from targeted C. difficile infection control interventions. Infect Control Hosp Epidemiol 2017;1-3.

Antibiotic-associated infections with Clostridioides difficile are a severe and often lethal risk for hospitalized patients, and can also affect populations without these classical risk factors. For a rational design of therapeutical concepts, a better knowledge of the metabolism of the pathogen is crucial. Metabolic modeling can provide a simulation of quantitative growth and usage of metabolic pathways, leading to a deeper understanding of the organism. Here, we present an elaborate genome-scale metabolic model of C...

PROBLEM: Albert Einstein defines insanity as doing the same thing over again but expecting different results. Although the United States claims to reduce antibiotic abuse, practice strict isolation, and clean meticulously, the burden of Clostridium difficile outpaces goals. Unless innovative approaches are tried, we risk culling elderly, immunosuppressed, and otherwise debilitated populations. Emergency departments are a primary access point for patients who are unable to wait for primary care...
