Over the last decade, the incidence and severity of Clostridium difficile infection (CDI) have significantly increased, leading to a rise in CDI-associated hospitalizations, health care costs, and mortality. Although treatment options exist for CDI, recurrence is frequent following treatment. Furthermore, patients with at least one CDI recurrence are at an increased risk of developing additional recurrences. A novel approach to the prevention of recurrent CDI is the use of monoclonal antibodies directed against the toxins responsible for CDI as an adjunct to antibiotic treatment...

Clostridium difficile is a clinically significant pathogen that causes mild-to-severe (and often recurrent) colon infections. Disease symptoms stem from the activities of two large, multi-domain toxins known as TcdA and TcdB. The toxins can bind, enter, and perturb host cell function through a multi-step mechanism of receptor binding, endocytosis, pore formation, autoproteolysis, and glucosyltransferase-mediated modification of host substrates. Monoclonal antibodies that neutralize toxin activity provide a survival benefit in preclinical animal models and prevent recurrent infections in human clinical trials...

BACKGROUND: Rehabilitation clinics may vary widely in terms of type of care provided, duration of hospital stay, and case severity. Only few data are available on prevalence of Clostridium difficile or extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) colonization in rehabilitation clinics in Germany. AIM: This study investigated the frequency of intestinal colonization by these pathogens among patients in rehabilitation clinics of different specialization...

Clostridium difficile (C. difficile) is an anaerobic gram-positive pathogen that is the leading cause of nosocomial bacterial infection globally. C. difficile infection (CDI) typically occurs after ingestion of infectious spores by a patient that has been treated with broad-spectrum antibiotics. While CDI is a toxin-mediated disease, transmission and pathogenesis are dependent on the ability to produce viable spores. These spores must become metabolically active (germinate) in order to cause disease. C. difficile spore germination occurs when spores encounter bile salts and other co-germinants within the small intestine, however, the germination signaling cascade is unclear...

BACKGROUND: The optimal regimen for perioperative antimicrobial prophylaxis is controversial. Use of combination prophylaxis with a beta-lactam plus vancomycin is increasing; however, the relative risks and benefits associated with this strategy are unknown. Thus, we sought to compare postoperative outcomes following administration of 2 antimicrobials versus a single agent for the prevention of surgical site infections (SSIs). Potential harms associated with combination regimens, including acute kidney injury (AKI) and Clostridium difficile infection (CDI), were also considered...

Clostridium difficile infection (CDI) is a high-impact hospital acquired condition and chief driver of excess morbidity, mortality, and treatment cost. Diagnosis, treatment, and prevention of clostridium difficile infection is key component of any hospital based practice. Urologists see a small percentage of all patients with CDI, however they traditionally utilize antibiotic agents that put patients at risk for CDI. Urologic procedures making use of bowel have a significantly higher rate of CDI than other procdures...

Antibiotics are frequently prescribed in hospitalized and in outpatients. We review four important aspects for their daily prescription. In elderly patients, the prescription should take into account changes in the volume of distribution and the usual decline in renal function even in the absence of chronic kidney disease. Particular antibiotics can trigger infection with Clostridium difficile. We discuss actual and novel strategies for its prevention. Renal toxicity of antibiotics includes acute tubular necrosis, interstitial nephritis and crystals obstructing renal tubule, depending on the class of antibiotics...

Clostridium difficile is the number one cause of nosocomial antibiotic-associated diarrhea in developed countries. Historically, pathogenesis was attributed two homologous glucosylating toxins, toxin-A (TcdA) and toxin-B (TcdB). Over the past decade, however, highly virulent epidemic strains of C. difficile (B1/NAP1/027) have emerged and are linked to an increase in morbidity and mortality. Increased virulence is attributed to multiple factors including: increased production of A- and B-toxins; production of binary toxin (CDT); and the emergence of more toxic TcdB variants (TcdB(027))...

INTRODUCTION Healthcare associated infections (HCAIs) are falling following widespread and enforced introduction of guidelines, particularly those that have addressed antibiotic resistant pathogens such as methicillin resistant Staphylococcus aureus or emergent pathogens such as Clostridium difficile, but no such decline has been seen in the incidence of surgical site infection (SSI), either in the UK, the EU or the US. SSI is one of the HCAIs, which are all avoidable complications of a surgical patient's pathway through both nosocomial and community care...

The incidence of Clostridium difficile associated diarrhoea (CDAD) is greater in elderly patients. Probiotics may have a beneficial effect in the prevention of CDAD. However, their effect in elderly orthopaedic patients has not been previously reported. Between April 2013 and April 2014, 105 patients admitted with femoral neck fractures, and who required 3days of antibiotics for infection of any cause, were prescribed the probiotic ACTIMEL until 3days after the last antibiotic dose. The incidence of CDAD was compared with historical controls (April 2011-April 2012)...

Clostridium difficile infection (CDI) is the most common nosocomial infection in the U.S. 25% of CDI patients go on to develop recurrent CDI (rCDI) following current standard of care (SOC) therapy, leading to morbidity, mortality and economic loss. The first passive immunotherapy drug targeting C.difficile toxin B (bezlotoxumab) has been approved recently by the FDA and EMA for prevention of rCDI. Areas covered: A body of key studies was selected and reviewed by the authors. The unmet needs in CDI care were ascertained with emphasis in rCDI, including the epidemiology, pathophysiology and current management...

The increased incidence of antibiotic resistant 'superbugs' has amplified the use of broad spectrum antibiotics worldwide. An unintended consequence of antimicrobial treatment is disruption of the gastrointestinal microbiota, resulting in susceptibility to opportunistic pathogens, such as Clostridium difficile. Paradoxically, treatment of C. difficile infections (CDI) also involves antibiotic use, leaving patients susceptible to re-infection. This serious health threat has led to an urgent call for the development of new therapeutics to reduce or replace the use of antibiotics to treat bacterial infections...

BACKGROUND: Recognition of a broad spectrum of disease and development of Clostridium difficile infection (CDI) and recurrent CDI (rCDI) in populations previously considered to be at low risk has renewed attention on differences in the risk profile of patients. In the absence of primary prevention for CDI and limited treatment options, it is important to achieve a deep understanding of the multiple factors that influence the risk of developing CDI and rCDI. METHODS: We conducted a review of systematic reviews and meta-analyses on risk factors for CDI and rCDI published between 1990 and October 2016...

Clostridium difficile infection is a common cause of diarrhea in long-term care facility (LTCF) patients. The high prevalence of C difficile infection in LTCFs noted in our study calls for a critical need to educate LTCF staff to send diarrheal stool for C difficile testing to identify more cases and prevent transmission.

Clostridium difficile causes antibiotic associated diarrhea and is a major public health concern. Current therapies disrupt the protective intestinal flora, do not reliably prevent recurrent infections and will be decreasingly effective should less susceptible strains emerge. CRS3123 is an oral agent that inhibits bacterial methionyl-tRNA synthetase, has potent activity against C. difficile and aerobic Gram positive bacteria, but little activity against Gram negative bacteria, including anaerobes. This first-in-human, double-blind, placebo-controlled, dose-escalation study evaluated the safety and systemic exposure of CRS3123 after a single oral dose in healthy adults...
