fecal microbiota transplant to treat recurrent clostridium difficile infections.the prevalence of recurrent or refractory clostridium difficile infection has been steadily increasing since 2000. consequently, alternative treatments to the standard antibiotic therapies are now being considered. one alternative treatment is fecal microbiota transplant. although fecal microbiota transplant is relatively new--and not appealing to most people--it has been around for many years and has great promise as an inexpensive, safe, and efficient treatment of refractory and recurrent c di ...201525834008
regional differences in clostridium difficile infections in relation to fluoroquinolone and proton pump inhibitor use, finland, 2008-2011.several antimicrobial agents and proton pump inhibitors (ppis) have been identified as risk factors for clostridium difficile infections (cdis). nationwide laboratory-based surveillance of cdis in finland since 2008 has shown variation in regional cdi rates. we evaluated whether regional differences in cdi rates were associated with antibacterial and ppi use.201525832317
editorial commentary: clostridium difficile ribotype 027: an intrinsically virulent strain, but clinical virulence remains to be determined at the bedside. 201525828996
clostridium difficile ribotype 027: relationship to age, detectability of toxins a or b in stool with rapid testing, severe infection, and mortality.clostridium difficile infection (cdi) can cause severe disease and death, especially in older adults. a better understanding of risk factors for adverse outcomes is needed. this study tests the hypotheses that infection with specific ribotypes and presence of stool toxins independently associate with severity and constructs predictive models of adverse outcomes.201525828993
dynamic changes in short- and long-term bacterial composition following fecal microbiota transplantation for recurrent clostridium difficile infection.fecal microbiota transplantation (fmt) is an effective treatment for recurrent clostridium difficile infection (cdi) that often fails standard antibiotic therapy. despite its widespread recent use, however, little is known about the stability of the fecal microbiota following fmt.201525825673
[fecal microbiota transplantation in recurrent clostridium difficile infections. framework and pharmaceutical preparation aspects].the fecal microbiota transplantation consists in introducing a preparation constituted by a dilution of stools of a healthy donor in the digestive tract of a patient recipient, to restore his intestinal physiological balance. this therapeutic approach was the subject of numerous studies showing its efficiency in the treatment of the recurrent infections with clostridium difficile. the fecal microbiota transplantation has now a high level of clinical evidence, which explains that it appears in va ...201525825054
berberine blocks the relapse of clostridium difficile infection in c57bl/6 mice after standard vancomycin treatment.vancomycin is a preferred antibiotic for treating clostridium difficile infection (cdi) and has been associated with a rate of recurrence of cdi of as high as 20% in treated patients. recent studies have suggested that berberine, an alternative medical therapy for gastroenteritis and diarrhea, exhibits several beneficial effects, including induction of anti-inflammatory responses and restoration of the intestinal barrier function. this study investigated the therapeutic effects of berberine on p ...201525824219
rapid, accurate, and on-site detection of c. difficile in stool samples.a rapid test to diagnose clostridium difficile infection (cdi) on hospital wards could minimize common but critical diagnostic delay. field asymmetric ion mobility spectrometry (faims) is a portable mass spectrometry instrument that quickly analyses the chemical composition of gaseous mixtures (e.g., above a stool sample). can faims accurately distinguish c. difficile-positive from -negative stool samples?201525823766
infections and antimicrobial use among institutionalized residents in hungary: increasing need of microbiological surveillance.as a result of the age-related changes, more elders live in long-term care facilities (ltcfs). due to their susceptibility, infections and excess use of antimicrobials are common. the aim was to estimate the burden of infections and antimicrobial use in hungarian ltcfs in order to increase the attention given to the prevention. european-wide point prevalence survey was conducted between april and may 2013. for each resident who had a signs and symptoms of an infection and/or treated with an anti ...201525823452
saccharomyces boulardii for the prevention of hospital onset clostridium difficile infection.probiotics, including saccharomyces boulardii, have been advocated for the prevention of clostridium difficile infection. the aim of this project was to evaluate the effects of the removal of s. boulardii from an automatic antibiotic order set and hospital formulary on hospital onset c. difficile infection rates.201525822430
the epidemiology and economic burden of clostridium difficile infection in korea.the prevalence of clostridium difficile infection and the associated burden have recently increased in many countries. while the main risk factors for c. difficile infection include old age and antibiotic use, the prevalence of this infection is increasing in low-risk groups. these trends highlight the need for research on c. difficile infection. this study pointed out the prevalence and economic burden of c. difficile infection and uses the representative national data which is primarily from t ...201525821807
insight into alteration of gut microbiota in clostridium difficile infection and asymptomatic c. difficile colonization.clostridium difficile is well recognized as the common pathogen of nosocomial diarrhea, meanwhile, asymptomatic colonization with c. difficile in part of the population has also drawn public attention. although gut microbiota is known to play an important role in the pathogenesis of c. difficile infection (cdi), whether there is any alteration of gut microbial composition in asymptomatic c. difficile carriers hasn't been clearly described. the purpose of this study was to explore the differences ...201525817005
