BACKGROUND/AIMS: Accurate and rapid laboratory diagnosis of Clostridium difficile infections (CDI) remains a significant challenge. A two-step algorithm for detection of toxigenic C. difficile in stool based on initial screening for glutamate dehydrogenase assay followed by confirmation by toxin A+B detection using an enzyme immunoassay (EIA) or molecular assay has been proposed. We aimed to evaluate the C. difficile Quik Chek Complete® (QCC-EIA) versus the GeneXpert® C. difficile polymerase chain reaction (PCR) assay in this two-step algorithm...

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...

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 Clostridium difficile infection (CDI) and asymptomatic carriage of toxigenic C. difficile are common in long-term care facilities (LTCFs). However, whether C. difficile is frequently acquired in the LTCF versus during acute-care admissions remains unknown. OBJECTIVE To test the hypothesis that LTCF residents often acquire C. difficile colonization and infection in the LTCF DESIGN This 5-month cohort study was conducted to determine the incidence of acquisition of C. difficile colonization and infection in asymptomatic patients transferred from a Veterans Affairs hospital to an affiliated LTCF...

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...

Different studies have suggested that the sand of public playgrounds could have a role in the transmission of infections, particularly in children. Furthermore, free access of pets and other animals to the playgrounds might increase such a risk. We studied the presence of Clostridium difficile in 20 pairs of sandboxes for children and dogs located in different playgrounds within the Madrid region (Spain). Clostridium difficile isolation was performed by enrichment and selective culture procedures. The genetic (ribotype and amplified fragment length polymorphism [AFLP]) diversity and antibiotic susceptibility of isolates was also studied...

Clostridium difficile is a Gram-positive bacillus that has become one of the main hospital-acquired human gastrointestinal infections in recent years. Its incidence is on the rise, involving more virulent strains, affecting new and previously uncontemplated groups of patients, and producing changes in clinical presentation and treatment response that influence disease outcome. Early diagnosis and disease stratification based on the severity of C.difficile infection are essential for therapeutic management and the implementation of containment measures...

BACKGROUND: Increased prescribing of proton pump inhibitors (PPIs) in the past few decades can be attributed mainly to long-term use of this type of therapy. Recent evidence indicates signals of harm associated with long-term use of PPIs, such as increased risk of Clostridium difficile infection, recurrence of C. difficile infection, and fracture. A few studies have assessed the effectiveness of step-down management of patients receiving long-term PPI therapy in ambulatory care settings...

The pathogenesis of CD is complex and it is thought to be associated with the environment, immune, hereditary, microbe and other factors. If the balance between the host and the intestinal microbes in CD patients was broken, immune-inflammatory response of susceptible individuals might be triggered. Probiotics could improve the intestinal microbial flora balance and treat human effectively. There are several new mechanisms which might explain the role of probiotics. Fecal microbiota transplantation (FMT) is becoming more and more attractive in treating a large amount of digestive system diseases which are related to the dysbiosis of intestinal microbiota...
