Filter by:Safety and efficacy of direct thrombin inhibitors versus enoxaparin in patients with staphylococcus aureus bacteraemia. The study hypothesizes that inhibition of the coagulase-activity of S. aureus by direct thrombin inhibitors is safe and translates into a better outcome of patients with S. aureus bacteremia.
To demonstrate that the combination of daptomycin and fosfomycin is superior to daptomycin alone in the treatment of methicillin resistant Staphylococcus aureus (MRSA) bacteremia.
Would rapid identification of bacteria and rapid detection of methicillin-resistant S. aureus (MRSA) and vancomycin-resistant enterococci (VRE) (using an FDA-cleared assay) in positive blood culture bottles improve patient care at Mayo Clinic Rochester (or just lead to increased cost)?
Evaluate the efficacy of a sequential regimen of 14 days in patients with catheter-related bacteremia by S. aureus methicillin-susceptible, selected based on a pre-established clinical and microbiological criteria.
Sepsis is a significant cause health care expenditure and carries an extremely high rate of morbidity and mortality if not treated appropriately. From 1979 to 2000, sepsis resulted in over 10 million admissions to hospital in the United States with a mortality rate of 17.9 to 27.8 percent. In Canada, it is estimated that the incidence of sepsis from 2008-2009 was 103.3 per 100,000 per year. Advances in the multifaceted management of sepsis in recent years have resulted in improved clinical outcomes. However, the cornerstone of sepsis management relies on the prompt administration of appropriate antibiotics. Current clinical practice suggests that antibiotic administration can be delayed up to 45 minutes in order to obtain blood cultures, whose results have a profound impact on the type and duration of antimicrobial therapy. Unfortunately, this recommendation is based on very little evidence and the investigators have found that potential life-saving treatment is often delayed in order to abide by it. Furthermore, recent data suggest that mortality could be increased by approximately 5% by delaying antibiotic administration for that time period. The investigators therefore wish to organize a prospective, multi-centre trial in order to identify the effect of antibiotic administration on blood culture positivity in patients presenting with severe sepsis or septic shock. Other objectives will be to elucidate which patient factors, including age, co-morbid conditions and clinical presentation, as well as antibiotic choice will affect blood culture results. This study will be conducted in the emergency departments at St. Paul's Hospital (SPH), Vancouver General Hospital (VGH), Lion's Gate Hospital (LGH), Surrey Memorial Hospital, Montreal General Hospital (MGH), Royal Victoria Hospital (RVH) and Maricopa Integrated Health System. Patients identified for the aforementioned conditions will be treated as per routine hospital protocol. If the patient is deemed eligible for the study, a second set of blood of blood cultures will subsequently be drawn ideally between 30 and 60 minutes after the administration of antibiotic therapy. Subject demographic data will be collected pertaining to age, comorbid immunocompromised conditions, vital signs, laboratory tests pertaining to end organ dysfunction, suspected source of sepsis, the type antibiotics administered and the timing of antimicrobial administration with respect to the second set of blood cultures taken. Our hypothesis is that blood culture positivity in patients presenting with severe sepsis and septic shock will not be altered significantly by antibiotic therapy. If so, our study would strongly argue against delaying life-saving therapy and would thus greatly improve patient care in our local emergency rooms. If incorrect, our study would be the first to demonstrate the benefit of obtaining blood cultures before antibiotic therapy and would strengthen current recommendations.
Patients with a hematological malignancy who are undergoing intensive chemotherapy need a central venous catheter (CVC)during their treatment. CVCs are locked with heparin when they are not used. The purpose of this study is to determine whether concentrated citrate locking, compared to heparin, reduces the incidence of central venous catheter-related thrombosis and infections in patients with hematological malignancies undergoing intensive chemotherapy.
A simplified graded gut decontamination protocol combined with rigorous bi-weekly screening and appropriate bacterial prophylaxis, will lead to a 25% reduction in the acquisition of blood stream infections and to a 25% reduction in lower airway colonization with multi drug resistant organisms. There will be no concomitant rise in gram-positive or fungal infection or a surgency of new resistance patterns.
Main objective: to observationally assess the efficacy of different antimicrobials in Bloodstream Infection (BSI) due to Enterobacteriaceae producing ESBLs or carbapenemases. Specific objectives: Bacteraemic infections due to ESBL-producing Enterobacteriaceae: - To demonstrate that β-lactam/β-lactam inhibitors are not associated with worse cure rate and mortality than carbapenems after controlling for confounders, both as empirical and definitive therapy. - To demonstrate that fluoroquinolones as definitive therapy are not associated with worse cure rate and mortality than carbapenems after controlling for confounders. - To demonstrate that empirical cephalosporins in monotherapy are associated with worse cure rate and mortality than carbapenems after controlling for confounders in infections others than urinary tract infections. - To demonstrate that the association of active aminoglycosides with cephalosporins or fluoroquinolines is not associated with worse cure rate and mortality than carbapenems after controlling for confounders. - To demonstrate that combination empirical and definitive therapy is not associated with better cure rate than monotherapy after controlling for confounders. - For tigecycline, colistin, and fosfomycin, no hypothesis. The objective is to provide adjusted estimations of their association with outcome variables in comparison with carbapenem monotherapy according to clinical situation and infection. Bacteraemic infections due to carbapenemase-producing Enterobacteriaceae: - To demonstrate that combination therapy is associated with worse cure rate and mortality than monotherapy after controlling for confounders. - To show that carbapenems are associated with worse cure rate and mortality when used in infections other than urinary tract caused by isolates showing MIC <2 µg/mL for imipenem or meropenem in comparison to those caused by isolates with higher MIC, after controlling for confounders. - To show that colistin used at a dose >6 million IU per day is associated with improved outcomes in comparison with lower dose, after controlling for confounders.
Peroral Endoscopic Myotomy (POEM) is a novel, promising endoscopic technique for achalasia because it is safer and more effective than traditional Heller's myotomy. However, the issue of antibiotic prophylaxis in POEM has evoked considerable controversy recently. Therefore, we conduct this study to elucidate the status of POEM-related bacteremia and procalcitonin levels in order to preliminary observe whether antibiotic prophylaxis is needed.
The investigators plan an open label randomized controlled trial to compare short-course antibiotic therapy (<=7 days) versus longer treatment (>7 days). The investigators will include hospitalized patients with gram-negative bacteremia. The investigators primary objective is to investigate the safety and efficacy of short-course antibiotics.
