Filter by:Staphylococcus aureus is the most frequent cause of both healthcare-associated and community-acquired bloodstream infections worldwide. Infective endocarditis (IE) has been detected in 5-17% of cases and is a determinant of poor prognosis. The investigators developed a score (the VIRSTA score) based on patients' characteristics to rule out IE with high confidence (negative predictive value (NPV) above 99%) in patients with SAB. This score, with a cut-off of 3 has been externally validated by two international studies which have also established its high NPV. The 2023 European society of cardiology (ESC) guidelines state that echocardiography should be considered in all patients with Staphylococcus aureus bacteremia (SAB) using risk scores (including VIRSTA score) to guide the use or not of echocardiography. While recommended, the investigators think that VIRSTA score must be evaluated in terms of patients' outcome.
Some rare cases of recurrent Campylobacter bacteraemia (RCB) exist with relapses months to years after an effective treatment and a negativation of all bacterial samples. As of today, only around 20 cases have been described in the international literature for the last 30 years. The cases are likely highly underreported. No study describes those recurrent Campylobacter bacteraemias at the scale of a country. The aim of this multicentre, nationwide, retrospective study is to describe their precise epidemiology in France for the last 25 years, the immune profile of the patients, the specificities of the bacteria involved, the treatments received and the evolution of these infections. The perspective is to propose a standardization of the medical care of those patients mainly by describing the effective treatments and the explorations of the immune system which should be considered.
Bacteremia is defined as the presence of bacteria in the blood. They can potentially lead to life-threatening septic shock. Effective probabilistic antibiotic therapy must therefore be initiated immediately after blood cultures have been taken. To diagnose bacteremia, blood culture bottles must first be incubated, which allows bacterial growth and early detection. Then, as soon as the sample is positive, an antibiogram of the incriminated bacterium is carried out by inoculation on MH (Mueller Hinton) medium. This diffusion antibiogram is the reference method and is obtained 24 hours after the vial is positive, i.e. around 48 hours after blood cultures are taken. American recommendations agree that it is crucial to use rapid diagnostic tests to obtain the antibiogram. Antibiotic susceptibility test data can be used to broaden the spectrum of antibiotics in the event of ineffective therapy. They can also be used to reduce the spectrum of broad-spectrum antibiotics. This is part of the proper use of antibiotics and the reduction of multi-resistant bacteria (MRB) or highly resistant bacteria (HRB). Finally, it is also possible to carry out an early oral relay, thus avoiding intravenous infusions and their complications, and potentially reducing hospitalization times. The investigators have evaluated a rapid antibiogram by diffusion on MHR-SIR (Mueller-Hinton Rapid-SIR) medium from the blood culture bottle. The investigators were able to obtain antibiogram results 7 hours after blood culture positivity, with excellent correlation compared with the standard method after 24 hours incubation on MH (Mueller-Hinton). The antibiotics tested were the same as with the standard method. Secondly, The investigators were able to evaluate prospectively the impact of diffusion antibiotic susceptibility testing on MHR-SIR medium on early modification of antibiotic therapy in bacteremia, on 167 patients Antibiotic susceptibility test data on MHR-SIR enabled us to adapt antibiotic therapy 8 hours after blood culture positivity for 74 patients (44%). Antibiotic therapy was ineffective for 30 patients (18%) and was therefore extended. It also enabled us to reduce the spectrum of antibiotic therapy, in particular through early oral relay, for 44 patients (26%). The aim of this multicenter trial is to validate on a large scale this strategy for obtaining rapid antibiotic susceptibility test results, with significant consequences in terms of optimizing antibiotic therapy.
Although controversy exists regarding the efficacy of antibiotic prophylaxis for patients at risk of infective endocarditis, expert committees continue to publish recommendations for antibiotic prophylactic regimens. The last American Heart Association (AHA) and European Society of Cardiology (ESC) guidelines include several important changes, highlighting that clindamycin (CLI) is no longer recommended as an alternative to amoxicillin in those allergic to penicillin. This new project aims to evaluate the effectiveness of oral doxycycline in preventing post-dental extraction bloodstream infection.
Ceftazidime-avibactam and aztreonam combination (CAZAVI + ATM) presents a potential alternative for the treatment of metallo-beta-lactamase (MBL)-type carbapenemase-producing Enterobacteriaceae (CPE) bacteremia, particularly where Cefiderocol is not readily available. This study proposes a Target Trial Emulation (TTE) to assess the efficacy and safety of CAZAVI + ATM compared to other active antibiotics (OAAs) in patients with MBL-type CPE bacteremia, and also to evaluate all-cause 30-day mortality, resistance profiles of isolated microorganisms, clinical failure rates, leukocyte count normalization, adverse events, occurrence of Clostridium difficile infection, and emergence of new multidrug-resistant microorganisms. The study expects to enroll at least 662 patients from 22 hospitals in Argentina. Data will be collected through the REDCap database, with rigorous verification for completeness and accuracy. The outcomes of this project will contribute vital insights into the efficacy and safety of CAZAVI + ATM, informing clinical practice guidelines for the management of MBL-type bacteremia across diverse settings.
The Early Intravenous to Oral Antibiotic Switch in Uncomplicated Staphylococcus aureus Bacteraemia (EVOS) study is a multicentre, randomized, open-label, parallel group, phase 3, non-inferiority trial of early intravenous to oral antibiotic switch in comparison with standard intravenous antibiotic regime among patients with uncomplicated Staphylococcus aureus bacteraemia (SAB). The study is based on the hypothesis that an early switch from IV to oral antimicrobial therapy is non-inferior and safe compared to conventional minimum 14-day course of IV therapy in patients with low-risk uncomplicated SAB.
The goal of this study is to create a computer simulation of patients with bloodstream infection to understand how changes in healthcare policies and resources affect patient treatment. This simulation will help doctors and health-care decision makers make better choices in treating these patients and avoid overusing antibiotics that can lead to antibiotic resistance. Antibiotic resistance is when bacteria can't be killed by antibiotics anymore. Participants will not receive treatments as this is an observational study, but the study will involve: - Interviews with healthcare staff to understand patient care pathways. - Analysis of historical data on bacteria causing infections and antibiotic treatments. - A 30-day observational study to observe patient treatment for bloodstream infections.
ARO-DECAMP is a multi-centre, placebo-controlled, pilot and feasibility randomized controlled trial for the microbial consortium Microbial Ecosystem Therapeutic-2. Non-intensive care unit patients ≥ 18 years old diagnosed with a bloodstream infection and receiving treatment for an antibiotic resistant organism will be included. Participants will be randomized to receive either MET-2 or placebo for 10 days. Recruitment rate and study intervention adherence will be evaluated for feasibility. Participants will be followed for 180 days, and biological samples will be collected periodically for clinical, ecological, and biomarker outcomes.
This study is designed to evaluate the clinical and antibacterial efficacy, safety and pharmacokinetics of the drug Fluorothiazinone compared to placebo to prevent nosocomial gram-negative bacterial infections with participation of patients on mechanical ventilation. The main objectives of this study are: - Evaluation of the clinical and antibacterial efficacy of the drug Fluorothiazinone in combination with standard measures for the prevention of nosocomial infections compared to placebo in combination with standard measures for the prevention of nosocomial infections for the prevention of nosocomial infections caused by bacterial gram-negative flora in patients on mechanical ventilation. - Evaluation of the safety and tolerability of the drug Fluorothiazinone in patients on mechanical ventilation. - Evaluation of the pharmacokinetics (in whole blood) of the drug Fluorothiazinone with a single daily dose of 2400 mg/day. Researchers will compare results for the treatment and the placebo arms.
Patients with bloodstream infections, hospital acquired pneumonia or ventilator-associated pneumonia caused by carbapenem-resistant Acinetobacter baumannii (CRAB) treated with cefiderocol combined with ampicillin sulbactam will be compared to patients treated treated with colistin alone or colistin combined with meropenem.
