Filter by:Background: Staphylococcus aureus bacteremia (SAB) is frequently encountered in hospitals, with high rates of morbidity and mortality. Duration of antimicrobial treatment for SAB, other than in cases of Infective endocarditis (IE), recommended by different guidelines relies on risk stratification for relapse of infection rather than definite diagnosis of septic foci that eventually determine the relapse rate. In recently published studies fluorodeoxyglucose (FDG) PET CT was found to be a sensitive imaging test for identifying metastatic infectious foci in Gram-positive bacteremia, including SAB. Objectives: To examine the impact of using FDG PET CT in the diagnostic algorithm of non-IE SAB compared to standard treatment recommendations on treatment duration and clinical outcomes. Methods: A prospective interventional non-comparative cohort study conducted at Rambam Health Care Campus. Patients with SAB, defined as microbiologically and clinically, will undergo FDG PET CT 10-14 days following the first positive blood culture for diagnosis of septic extra-cardiac foci of infection. Patients with IE will be excluded. Short (2 weeks) versus long treatment (4-6 weeks) will be recommended for negative and positive PET CT tests, respectively. Patients will be followed-up for 1 year for relapse of infection and mortality. We will document the sensitivity and specificity of PET CT for detection of complications among patients with SAB. We will examine the percentage of patients in whom the use of PET CT changed treatment duration compared to standard recommendations. We will compare also, the relapse rate and 1 year mortality rate with data from previous studies and local data. Assuming a 15% rate of management changes compared to consensus recommendations, a sample of 150 patients will achieve the required 95% CI. Significance: Our trial will serve for improving decision making in patients with non-IE SAB, shortening treatment duration in unnecessary cases and decreasing relapse rate by giving prolonged appropriate treatment for metastatic infection not identified by standard management algorithms. PET CT is assuming an increasingly important role in infection diagnosis and management. The current study will be the first to examine the role of PET CT in directing management of patients with SAB.
Implantable venous access port infections are mainly due to coagulase negative staphylococci and may be managed by antibiotic lock therapy with retention of the port. Most of the time a vancomycin lock is used. Experimental data show that vancomycin may be poorly effective in eradicating the staphylococcal biofilm in the port. Another disadvantage of Vancomycin-containing lock solution is the occurrence of resistant organisms and the risk of catheter occlusion. Ethanol-containing lock solution is highly effective in vitro and does not expose to the risk of emergence resistance.
Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major sources of nosocomial infection. Along with the widely application of antibiotics around perioperative period, MRSA infection is increasing by years.Fecal microbial transplantation (FMT),infusion of fecal preparation from a healthy donor into the GI tract of a patient is being proposed as a novel therapeutic approach to modulate diseases associated with pathological imbalances within the resident microbiota, termed dysbiosis.It has been used to treat intestinal disease such as inflammatory bowel diseases and Clostridium difficile infection, but no reports are available on its role in treating MRSA enteritis yet. vancomycin is the first choice to treat MRSA but can also lead to an increase in antibiotic resistant organisms such as vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus and transfer of antibiotic resistance genes among the microbial community. So FMT seems a more harmless and reasonable measure to treat similar diseases.
The aim of this clinical trial is to determine whether a novel combination antibiotic treatment (vancomycin/daptomycin + beta-lactam) is superior to the standard antibiotic treatment (vancomycin/daptomycin) for hospitalised adults with Methicillin Resistant Staphylococcus aureus bacteraemia. The hypothesis is that the addition of beta-lactam antibiotics (these are antibiotics from the penicillin family) to the standard therapy will lead to more efficient bacterial killing and hence lead to faster clearance of bacteria from the blood stream and other areas of infection, thereby reducing the risk of the spread of infection and death. The study design is an investigator-initiated, multi-centre, open-label, randomised controlled trial. This will include 440 participants diagnosed with Methicillin Resistant Staphylococcus aureus bacteraemia recruited over a period of 4 years (July 2015 - June 2019) from within Infectious Diseases inpatient units across 21 hospital sites including 18 from within Australia and 3 located in Singapore. Participation will be voluntary and subject to informed consent. The participants will be randomised 1:1 to either the standard therapy group or combination therapy group. The combination therapy will include a treatment of intravenous beta-lactam for the first 7 days of treatment, in addition to the standard treatment (either vancomycin or daptomycin). The primary outcome measure will be complication-free survival 90 days post randomisation.
The purpose of this study is to evaluate the safety and immunogenicity of a single vaccination of an investigational vaccine against Staphylococcus aureus (SA4Ag) in healthy adults aged 18 to <65 years.
Given that the Emergency Department (ED) has become the entry way for large populations of patients into the health care system, a strategy of sampling MRSA isolates in ED populations and merging this information with patient-level data may present a window to hypothesize and investigate CA-MRSA transmission within the community and its impact on hospital-acquired infections.
This research study is looking at an antibiotic medicine, Ceftaroline Fosamil (Ceftaroline), which fights infections like the one the subject has. Ceftaroline is effective against S.aureus germs including those that are called Methicillin Resistant Staphylococcus aureus (MRSA.) Ceftaroline has been approved by the U.S. Food and Drug Administration (FDA) for use in adults and children with Community-Acquired Bacterial Pneumonia [a type of lung infection] and Acute Bacterial Skin and Skin Structure Infections. Ceftaroline is not yet approved for treatment in subjects with hematogenous osteomyelitis, therefore, the use of Ceftaroline in this research study is considered "investigational". The goal of this research study is to find out what side effects there may be when children are taking Ceftaroline and to study how effective Ceftaroline is in treating bone infections due to Staphylococcus aureus in children. The investigators are also studying what the body does to the study drug, Ceftaroline, and if the doses the investigators use result in blood levels that the investigators think are going to be effective against bone infections in children. This is called pharmacokinetics (PK).
This study will assess the nasal eradication of SA in healthy subjects following treatment with mupirocin 2% (Bactroban 2% Nasal Ointment) twice daily for 5 days, by means of a broth enriched culture microbial assay. The sensitivities of broth enrichment and plating assay methods will be compared. The safety and tolerability of Bactroban 2% Nasal Ointment will also be assessed.
This trial will test the hypothesis that treating parents of neonates requiring NICU care with intranasal mupirocin and topical chlorhexidine bathing will reduce the spread of S. aureus from parents to neonates.
The purpose of this study is to treat persistent MRSA carriers with vitamin D supplementation during a 12 month to see if the number of MRSA positive patients can be reduced.
