long-term follow-up of fecal microbiota transplantation for treatment of recurrent clostridium difficile infection in a dual solid organ transplant recipient.clostridium difficile infection is one of the most frequent causes of healthcare-associated infections, and its rates are also increasing in the community. mounting evidence suggests that fecal microbiota transplantation (fmt) may be effective; however, as there is paucity of data regarding the use of fmt in patients with solid organ transplants, we present a case of successful fmt in a patient with dual solid organ transplant.201726078735
antimicrobial resistance: thinking outside the box.the health care system is challenged by another serious issue: antimicrobial resistance. clostridium difficile is the most common infection in health care institutions and is becoming resistant to standard treatment. carbapenem-resistant enterobacteriaceae can be found in almost every state in the united states. confounding the antimicrobial resistance issue is the fact that few new antimicrobials are being developed by pharmaceutical companies. the situation is so critical that the white house ...201726200730
long-term follow-up study of fecal microbiota transplantation for severe and/or complicated clostridium difficile infection: a multicenter experience.our aim was to investigate fecal microbiota transplantation (fmt) efficacy in patients with severe and/or complicated clostridium difficile infection (cdi).201726125460
strategies for appropriate antibiotic use in intensive care unit.the comsumption of antibiotics is high, mainly in intensive care units. unfortunately, most are inappropriately used leading to increased multi-resistant bacteria. it is well known that initial empirical therapy with broad-spectrum antibiotics reduce mortality rates. however the prolonged and irrational use of antimicrobials may also increase the risk of toxicity, drug interactions and diarrhea due to clostridium difficile. some strategies to rational use of antimicrobial agents include avoiding ...201726132360
fecal microbiota transplant by push enteroscopy to treat diarrhea caused by clostridium difficile.clostridium difficile is the major etiological agent of pseudomembranous colitis and is found in up to 20% of adult inpatients. the recommended treatment is antibiotic therapy with metronidazole and/or vancomycin. however, the recurrence rate may reach up to 25% and it increases in each episode. the newest alternative to treat diarrhea due to recurrent clostridium difficile is fecal microbiota transplantation. the procedure was performed in 12 patients, with a 6-month follow-up on 10 of them. of ...201726154556
multifocal clinical performance improvement across 21 hospitals.improving quality and safety across an entire healthcare system in multiple clinical areas within a short time frame is challenging. we describe our experience with improving inpatient quality and safety at kaiser permanente northern california. the foundations of performance improvement are a “four-wheel drive” approach and a comprehensive driver diagram linking improvement goals to focal areas. by the end of 2011, substantial improvements occurred in hospital-acquired infections (central-line– ...201726247072
the impact of clostridum difficile on surgical rate among ulcerative colitis patients: a systemic review and meta-analysis.there is growing recognition of the impact of clostridum difficile infection (cdi) on patients with inflammatory bowel disease. clostridium difficile infection causes greater morbidity and mortality. this study aimed to evaluate the impact of c. difficile on surgical risk among ulcerative colitis (uc) patients. we searched the following databases: medline, embase, the cochrane central register of controlled trials, acp journal club, dare, cmr, and hta. studies were included if fulfilled the foll ...201726228363

indication of acid suppression therapy and predictors for the prophylactic use of protonpump inhibitors vs. histamine-2 receptor antagonists in a malaysian tertiary hospital.proton-pump inhibitors (ppi) and histamine-2 receptor antagonists (h2ra) are common acid suppressants used in gastrointestinal disorders. the trend of usage in malaysia has changed from predominantly h2ra to ppi from 2007 to 2008, 3.46 versus 2.87 and 2.99 versus 3.24 ddd (defined daily dose)/1000 population/day respectively. this raises concerns as ppi overutilization amounts to higher cost expenditure and are associated with various untoward consequences such as clostridium difficile-associate ...201726445624
integration of erm(b)-containing elements through large chromosome fragment exchange in clostridium difficile.in clostridium difficile, erm(b) genes are located on mobile elements like tn5398 and tn6215. in previous studies, some of these elements were transferred by conjugation-like mechanisms, mobilized in trans by helper conjugative systems. in this study, we analyzed the genomes of several recipient strains that acquired either tn5398 or tn6215-like elements. we demonstrated that the integration of the transposons in the genome of the recipient cell was always due to homologous recombination events, ...201726442177
[acute respiratory distress syndrome due to clostridium difficile colitis: a case report and review of the literature].clostridium difficile is a major cause of antibiotic-associated diarrhea. we report a patient with complicated clostridium difficile infection (cdi) who developed rapidly progressive acute respiratory distress syndrome (ards), for which cdi was the only identifiable source. cdi should be considered in the differential diagnosis for anyone with diarrhea who presents especially in high-risk groups such as the elderly, hospitalized patients, or those who have had a history of cdi.201726397285
the long-term efficacy and safety of fecal microbiota transplant for recurrent, severe, and complicated clostridium difficile infection in 146 elderly individuals.clostridium difficile infection (cdi) in the elderly has a higher prevalence, greater morbidity and mortality, and lower response to conventional treatment than the general population. fecal microbiota transplant (fmt) is highly effective therapy for cdi but has not been studied specifically in the elderly. this study aims to determine the long-term efficacy and safety of fmt for recurrent (rcdi), severe (scdi), and complicated (ccdi) cdi in elderly patients.201726352106
