Filter by:Worldwide emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) had become a major problem in ICU, with at least 10% of incidence at the admission in Europe. A systematic rectal swab is used in 70% of French ICU to detect intestinal ESBL-E carriage The relationship between intestinal carriage and ICU-acquired infection is not perfectly known. The investigators conducted a five years study monocentric retrospective observational cohort in patients with presence of extended-spectrum β-lactamase-producing Enterobacteriaceae in systematic rectal swabs to investigate which type of infections and which bacteria are involved. The investigators also collect data about antibiotherapy used to treat these infections.
There is a variety of in vitro, in vivo (animal model), and human case series data which suggests that the addition of ertapenem to cefazolin could improve outcomes in methicillin-susceptible S. aureus bacteremia. No randomized controlled trial has been performed.
In this observational study, it is aimed to investigate the mortality and morbidity rates of hospital-acquired blood stream infections that are treated in intensive care units (ICU). The effects of properties of the micro-organism such as type and antimicrobial resistance on the infection and its outcomes will be mainly explored. In addition, the impact of antibiotic options and other treatment modalities on survival of patients will be investigated. Twenty-seven different ICUs from Turkey will be included in this study.
The primary objective of the study is to identify the risk factors of community-acquired bacteremia to resistant bacteria. As the secondary objectives, the study aims - to describe the episodes of epidemiology of bacteremia (community-acquired and nosocomial) with inpatient patients in APHP. - to research a potential correlation between the incidence of community-acquired bacteremia of studied germs and the evolution of antibiotics consumption in general population in Île de France region. - to distinguish three categories of community-acquired bacteremia: real community-acquired infections, infections beginning in community (patients discharged a community care center within 3 months), the nosocomial infections (patients discharged a health center within 7 jours). Describe the epidemiology of resistance and the differential impact of individual exposure to antibiotics in these three categories. - to identify, according to pathogens, a temporal threshold from which a prior stay in a health center or HAD would impact on the occurrence of a community-acquired bacteremia with a resistant bacterium. - to describe prospectively for follow-up of 1 year for hospitalized patients for a community-acquired or nosocomial bacteremia: mortality at one month and 3 months, re-hospitalization for an infectious episode and isolated bacteria during this later episode.
Background: Survival in Granzyme A gene (gzmA) knocked-out mice was significantly longer than in wild-type mice in a murine peritonitis model (cecal ligation puncture). Hypothesis: GZM A has a pathogenic role in sepsis in humans and gzmA polymorphisms can help to predict the risk of sepsis among patients with systemic infections (E. coli bacteremic urinary tract infections). Objectives: 1. To assess the correlation between GZM A serum levels and systemic inflammatory response in a human model of infection/sepsis (E. coli bacteremic UTI) 2. To characterize gzmA polymorphisms among patients with E. coli bacteremic UTI 3. To determine GZM A serum kinetics among patients with E. coli bacteremic UTI 4. To characterize E. coli strains causing bacteremic UTI: antimicrobial phenotype and virulence factors ("virulome"). Methods: - Design and setting: Prospective nested case-control study - Study population: consecutive adult patients with bacteremic urinary tract infections (UTIs) caused by E. coli - Exclusion criteria: Patients with conditions that significantly compromise immune status or patients exposed to urologic procedures - Estimated sample size: 50 patients with a sepsis/ non sepsis 1:1 ratio. Septic and non septic patients will be matched on gender, age (+/- 10 years), comorbidity (Charlson score +/-1), time symptom onset to blood culture (+/- 24h) - Measurements: GZM A serum levels will be determined on day 0, day 2-3, day 30. GZM A kinetics, gzmA polymorphisms (whole exome sequencing).Whole genome sequencing of E. coli isolates retrieved from blood cultures will be performed. - Analysis: Association between GZM A levels and gzmA polymorphisms and sepsis will be analyzed adjusting for patient, infection and microorganism-related factors (multivariate analysis).
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.
To compare the time to pathogen eradication, and the relationship to the time to clinical improvement, between ceftaroline and case-matched vancomycin treated controls in the treatment of adults with serious infections caused by Methicillin-Resistant Staphylococcus aureus (MRSA).
The purpose of this study is to investigate the risk factor, molecular character and susceptibility change for recurrent ESBL-producing Enterobacteriaceae bacteremia
Infections caused by imipenem-resistant Acinetobacter baumannii are associated with high mortality and morbidity. The treatment choices for this resistant pathogen are limited. The objective of the present proposal is to evaluate the effectiveness of combination therapy of imipenem and sulbactam in patients contracted with A. baumannii, and to correlate the clinical effect with the in vitro synergistic results.
Before Daptomycin (Cubicin ®) approved by the U.S. FDA in 2003, There were large-scale clinical trials conducted that included more than 1,000 subjects and than Daptomycin got complicated skin and soft tissue infections (CSSSI) indication. After 2004, Daptomycin got new indications about bacteremia and endocarditis due to success outcomes in the clinical trial which included infected in blood flow and endocardial infected patients. All subjects in Daptomycin clinical trials are European and American race. It is necessary that collecting safety and efficacy data of Daptomycin in Taiwan race. I will intent to evaluate the safety and efficacy of Daptomycin which were used in patients with serious gram-positive infections retrospectively. And the outcome could be a reference for Daptomycin future using.
