Lactation (breastfeeding) mastitis is an acute infection of the milk ducts of the breastfeeding woman. Staphylococcus aureus (S. aureus) is the infectious germ most commonly associated with lactation mastitis. Twenty percent of the general population are carriers of Staphylococcus aureus, which means that they carry the infectious germ but do not become ill from it. It has been suggested that mothers who are carriers of S. aureus in their nostril may be at an increased risk of developing lactational mastitis, however; this has not been clinical proven. We are studying the relationship between S. aureus carrier status of breastfeeding mothers and infants and the risk of developing lactational mastitis. Additionally, we are collecting questionnaire data in an attempt to better define factors predisposing women to lactation mastitis.
To study whether fluoroquinolone (trovafloxacin or levofloxacin), added to standard treatment, could reduce the high mortality and complication rates in Staphylococcus aureus bacteremia.
This is a retrospective chart review study. The proposed study aims to document the risk factors for quinolone resistance in bloodstream isolates of Klebsiella species. Additionally, the adequacy of empiric antibiotic therapy for Klebsiella bloodstream infections will be assessed.
The purpose of this study is to determine the natural history of community-associated Staphylococcus aureus infections in both adult and pediatric patients by monitoring the rate of recurrent infections in those colonized with S. aureus. In addition, this study will evaluate the efficiency of commonly prescribed decolonization measures in patients presenting with S. aureus skin and soft tissue infections.
Primary Objective: Evaluate the efficacy and safety of daptomycin given for treatment of catheter-related bloodstream infections due to S. aureus bacteria with or without exchange of the central venous catheter (CVC) over guide wire in comparison with a historical control group of catheter-related S. aureus bacteremia treated with standard therapy (Vancomycin) or other active agents against staph aureus (such as beta-lactam antibiotics).
Outbreaks of skin and soft tissue infections (SSTI) related to community associated Methicillin-resistant Staphylococcus aureus (MRSA) have become increasingly common in military training units. Risk factors for MRSA related SSTI such as crowding, poor hygiene and shared equipment are often hard to avoid in a military training environment, often designed to simulate battlefield conditions. It has recently been demonstrated that military recruits colonized with MRSA may be at increased risk of developing SSTI. Studies in the hospital environment have shown that decolonizing inpatients known to carry MRSA decreases the rates of MRSA related infections in the treated individuals and also in their inpatient unit as a whole. The investigators propose a randomized, double blind, placebo controlled trial to: 1. Evaluate the effectiveness, feasibility, and safety of chlorhexidine body cloths, self-administered three times weekly, in preventing SSTI among recruits in military training facilities; and 2. Evaluate the effectiveness of chlorhexidine body cloths in decreasing rates of Staphylococcus aureus colonization among military recruits.
To establish the clinical test performance characteristics of sensitivity, specificity and predictive values for direct detection of nasal Staphylococcus aureus colonization against clinical microbiology laboratory culture methods.
Reduced susceptibility of Staphyloccus aureus to the glycopeptide antibiotic vancomycin is causing increasing concern worldwide in view of the threat of increased morbidity and mortality caused by such resistant organisms. MRL Pharmaceutical Services, a Division of Focus/MRL, has been contracted by NIAID to establish a Network on Antimicrobial Resistance in S. aureus (NARSA) to document cases where staphylococcal isolates with reduced susceptibility to vancomycin (MIC's greater than or equal to 4 micrograms/ml) have arisen and to procure such isolates into a central repository for distribution to registered approved researchers. MRL will be responsible for contacting sites where such isolates have been reported to discuss the test methods used to determine the reduced vancomycin susceptibility status of the isolate. Once the MRL Laboratory has determined that the isolate meets the criteria stated above, the site will be asked to ship the isolate to MRL as a possible candidate for inclusion in the NARSA Repository. The procurement strategy will involve issuing each isolate a temporary strain designation number which will be destroyed once the antibiotic profile of the isolate has been confirmed at MRL, thus preventing any link to the data generated by the site. The isolate and its antimicrobial susceptibility profile to several key drugs will be recorded in the NARSA Repository database. Demographic information related to the isolate and collected from the site includes: The Name of the Donor Site/Institution, City (to be held in a separate secured database, these data points are not available to registered user); State, Country of Donor Site; Isolation Date; Age; Sex; Patient Location; Patient Service; Culture Source; Reporting History. This information will be held in the Registry database. Since patient-specific information will not be collected, a request for a waiver of informed consent has been requested herein. NIAID funded investigators (NARSA Core Investigators) and other approved registered users whose research focuses on S. aureus will have access to the Registry/Repository database and will be able to request isolates for use in their research. Facility specific information will be held in a separate secured database that is not available to registered researchers unless approved through an IRB review.
The purpose of this study is to review medical records at MEDVAMC in order to relate the outcome of bacteremic MRSA infection to the antibiotics selected for treatment.
