Filter by:Background: In thoracic surgery, postoperative pneumonia (POP) is the leading cause of postoperative morbidity and mortality. The clinical diagnosis of POP is difficult and conventional microbiological diagnostic tests perform poorly. The contribution of molecular diagnostic tests (multiplex PCR, mPCR) should be evaluated to optimize the diagnostic and therapeutic management of POP. Objectives: The main objective is to describe the microbiological relationship between the existence of pre- (if available) and intra-operative bronchial and pulmonary bacterial colonization and the occurrence of POP. The secondary objectives are to analyze the contribution of the mPCR for the diagnosis of POP and to validate the predictive factors of POP described in the literature Material and methods: A monocentric prospective non-interventional research with minimal risks and constraints. The study population is represented by all the consecutive adult patients hospitalized for lung surgical resection (except surgical resection indicated for infectious disease) during one year. The preoperative respiratory samples within the 3 preceding months (date and type, pathogen and threshold) are recorded, if available. Intra-operative bronchial aspirate is performed for direct examination and culture (pathogen and threshold) and mPCR (PCR1). A mPCR is optionally performed on the surgical specimen (PCR2). In case of postoperative clinical suspicion of POP, invasive or non invasive samples of respiratory tract secretions are obtained for direct examination and culture (pathogen, threshold) and mPCR (PCR3). A clinical pulmonary infection score (CPIS) is calculated by integrating the results of conventional tests (CPIS1) and mPCR (CPIS2). The pre / intra operative and postoperative microbiological relationship will be described qualitatively and quantitatively and analyzed using correlation tests. Concordances and discrepancies between conventional tests and mPCR will be studied to analyze the contribution of molecular tests in this context.
VAPERO is a randomized, unblinded, controlled study to measure the impact of a strategy based on the Unyvero® multiplex PCR test on the adjustment of antimicrobial therapy in patients suspected with ventilator-associated or hospital-acquired pneumonia (VAP/HAP) requiring mechanical ventilation. The gold-standard microbiological diagnostic method for pneumonia in the ICU is still culture-based identification and antimicrobial susceptibility testing (AST) despite being more than a hundred years old, with results turnaround time spanning over several days, exposing patients to potentially inappropriate broad-spectrum antimicrobial therapy. The investigators aim to measure the impact of the Unyvero® testing strategy to improve the percentage of patients with VAP or HAP receiving early targeted antimicrobial therapy compared to standard care.
Secondary bacterial influenza pneumonia caused by Panton-Valentine Leukocidin Positive Staphylococcus aureus is a rare complication but with poor prognosis. This pathology seems to affect young patients (20-40 years) without any medical history. Since the influenza pandemic of 2009, this complication is more and more mentioned, sought and diagnosed. However, the literature is poor, consisting of case reports, experimental studies on murine models, and low-power studies. The main objective is to evaluate the mortality in intensive care units of patients post-influenza bacterial pneumonia due to a Panton-Valentine Leukocidin positive Staphylococcus aureus
The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.
The aim of this study is to estimate the burden of disease due to pneumococci, other bacteria and viruses in the African meningitis belt prior to pneumococcal conjugate vaccine introduction and to estimate the population impact of the vaccine after its implementation in 2014. In a defined population of a sanitary district in northern Togo, during the period 2010 to 2017, investigators enroll patients of all ages with suspected pneumonia requiring hospitalization or suspected bacterial meningitis. Patients are evaluated by bacteriology and molecular biology techniques on blood, cerebro-spinal fluid, nasal aspirates and by chest X-ray.
The purpose of the study is to assess the efficacy of an individualized approach to duration of antibiotic therapy based on each subject's clinical response compared to a local standard approach in patients coming from the community and who are hospitalized because of a pneumonia.
