Filter by:The investigators propose a pragmatic comparative effectiveness trial evaluating several decolonization strategies in patients with Staphylococcus aureus infection, their household contacts, and household environmental surfaces. The central hypothesis of this proposal is that an integrated approach of periodic personal and household environmental hygiene will reduce S. aureus transmission in households and subsequently decrease the incidence of skin and soft tissue infections (SSTI).
Nasal colonization with S. aureus is a risk factor for infection with this bacterium. A methodologically well conducted study of S. aureus bacteremia showed that 80% of S. aureus bacteremia with are due to the strain isolated in the nasal level. However, as part of a study coordinated by the CHU of Saint-Etienne, less than 50% of infections in prosthetic orthopedic devices have been linked to nasal carriage . Outside of exogenous infections, intestinal colonization with S. aureus could be an alternative source of endogenous infections with the waning of orthopedic surgery. In the general population, considering that about one third of the subjects were colonized with S. aureus nasal level and 1 in 5 in the intestine However the proportion of exclusive intestinal porting is not well known . This study will analyze, among ICU patients, porting S. aureus nasal and rectal level. It will better clarify the relationship between nasal and rectal ports and the risk of developing an infection.
This is an observational study that does not change routine care. The primary objective of this study is to investigate the role of antibiogramme-antibiofilmogramme concordance (in terms of S. aureus strains and prescribed antibiotics) in the presence/absence of S. aureus strains at the end of a first regimen of antibiotics.
The folliculitis decalvans (FD) is an orphan disease , common in consultation specialized on scalp. This disease is currently not curable, responsible for significant for patients. The pathophysiology is poorly understood, Staphylococcus aureus (SA) appears to play a role, never previously studied, and the study will attempt to clarify it. Controversies in the literature on the pathophysiological hypotheses can be summed up as follows : FD is it an infectious folliculitis where SA (almost always found on the lesions plays a direct role possibly aided by a lack of local immune protection , or is it a pustular inflammatory unknown cause where the SA has no direct role but is a cofactor or a simple germ superinfection. Our study has plans to bring new evidence to help decide between these two opposite but not mutually exclusive concepts .
The purpose of this research study is to compare the effectiveness of commonly used decolonization treatments (application of mupirocin antibiotic ointment to the nose and bleach baths) when performed by individuals with a history of skin and soft tissue infection (SSTI) in the prior year (individualized approach) in comparison to decolonization of all household members (household approach) in an attempt to prevent Staphylococcus aureus skin infections. The investigators hypothesize an individualized decolonization approach will be equally as effective as a household approach to prevent SSTI.
This is a Phase 1, first time in human study enrolling approximately 33 healthy adult subjects (18-65 yrs) from one study site. The purpose of this study is to evaluate the safety, tolerability and PK of MEDI4893 in healthy adult volunteers administered as a single IV dose compared with placebo, across 4 cohorts. The 4 dose cohorts will enroll sequentially. Subjects will be followed for safety from the time of Informed Consent through 360 days post dose.
Establish an international registry of over 400 patients with deep infections involving the bone and/or joint from≥20 centers representing all regions of the world with varied hospital and surgeon practice settings to ensure that registry analyses and research reflect typical clinical practice thereby providing optimal guidance for patients, clinicians, and healthcare researchers. Using a data collection platform that minimizes entry burden, collects most information at the time of surgery, and uses Internet technology to minimize data entry. The registry will include: 1. baseline patient attributes; 2. surgical approach, implants and technology; 3. hospital course; 4. surgeon and institutional characteristics; 5. longitudinal patient outcome, 6. post-procedure complications and revisions, 7. serum/tissue/drainage samples.
The purpose of this study is to evaluate strategies to prevent Staphylococcus aureus skin and soft tissue infections in soldiers during infantry training. This study will be conducted on three different bases among groups of male recruits to IDF training base. They will provide nasal swabs to detect Staphylococcus aureus carriage in two time points: 1. before mixing and training in confined settings, reflecting carriage acquired before entering 2. After 14-30 days. All soldiers will be under surveillance for skin infection until the end of the training program.
The zNose® MRSA test is a non-invasive breath test for markers of Staphylococcus aureus, which may predict the probability of bacterial organisms in the anterior nares, throat and respiratory tract, wounds, and anus and therefore be able to replace or supplement current active Methicillin Resistant Staphylococcus Aureus (MRSA) surveillance efforts. It consists of: - A collection apparatus for collection of volatile compounds from suspected infection sites onto a sorbent trap or Tedlar bag, as well as for the collection of a separate sample of room air. - Analysis of the volatile organic compounds from suspected infection sites and room air by short acoustic wave gas chromatography. - Interpretation of the volatile organic compounds with a proprietary algorithm in order to predict the probability of Staphylococcus aureus infection and colonization. This study will test the hypothesis that we can identify the presence of MRSA by sampling the "head space" above culture media of anterior nare samples provided by patients with MRSA. Additionally, this study will test the hypothesis that we can identify the presence of MRSA by sampling air exhaled through the nostrils (nasal exhalant).
Staphylococcus aureus, the most virulent of the many staphylococcal species, has been recognized as one of the most important and lethal human bacterial pathogens. With the increased incidence of methicillin-resistant staphylococcus aureus (MRSA) infection in community and hospitalized patients, MRSA infections are associated with greater lengths of stay, higher mortality, and increased costs. Vancomycin and teicoplanin, are the two most commonly used glycopeptides and are the first-choice of treatment for MRSA infection. Vancomycin-induced nephrotoxicity is still a point of controversy. Teicoplanin is not known to have any nephrotoxicity. Acute kidney injury is a common complication of critical illness, which is reported in 5 to 7% of hospitalized patients. It is associated with significantly increased mortality, length of stay, and costs across a broad spectrum of conditions.
