Filter by:Infective endocarditis (IE) is a rare (30 cases / million / year in France) and serious (20 % of deaths during hospitalization) disease . Its epidemiological profile was considerably modified these last years.New predisposing factors appeared, due to increasing number of patients wearing valvular prosthetics. The purpose of this study is to realize in 2008 a new observational study on populational basis to describe and analyze the evolution of the epidemiology of IE in France, compared to previous studies conducted in 1991 and 1999.
Infective endocarditis (IE) is associated with high hospital mortality for various reasons; one of them is circulatory failure in patients who undergo cardiac surgery for IE. One discussed reason underlying circulatory failure during surgery is the release of vasodilatatory mediators and cytokines. This study examines the efficacy and safety of a hemoadsorption filter which is approved for the reduction of the concentration of cytokines in the bloodstream.
Infective endocarditis (IE) is an infection of cardiac valves. IE mainly involves bacteria, more rarely fungi. IE is an uncommon diseases with an estimated incidence of 1-12 cases per 100,000 inhabitants per year. The diagnostic of IE relies on the culture of biological samples (blood cultures and per-operative samples) in the bacteriology laboratory in order to identify the pathogen and its susceptibility to antimicrobials. Nonetheless in about 10% of the cases, the blood cultures remain negative, due to antibiotics taken before harvesting, to non-culturable bacteria or to aseptic phenomena. Clinical metagenomics is defined as the application of high-throughput sequencing (NGS) followed by a specific bioinformatics analysis to obtain clinical information, i.e. pathogen identification and the prediction of their susceptibility to antimicrobials. The metagenome of a sample (i.e. all the genomes of the organisms present) virtually contains all the information necessary for bacteriological diagnosis: what is the pathogenic bacteria , and to which antibiotics it is susceptible. Hence, using clinical metagenomics in the context of IE appears seducing in order to overcome the limitations of conventional methods based on culture. Here, we propose to assess the performance of clinical metagenomics in the diagnostic of IE.
To evaluate the performance of a single high volume blood culture sampling strategy versus the actually used multiple sampling strategy for the diagnosis and categorization of infective endocarditis according to the Duke-Li classification in a Population of adults suspected of infective endocarditis.
Infective endocarditis (IE) is a severe clinical condition with a high in-hospital and 5-year mortality. It has a growing incidence, both related to healthcare and possibly to changes in prophylaxis recommendations regarding oral procedures. Though not a new disease, several aspects in its clinical and laboratory diagnosis remain to be better studied and innovated. The evaluation of systemic microvascular disease has proven crucial in the investigation and comprehension of pathophysiology of cardiovascular diseases, as well as a tool for early diagnosis and prediction of complications. Few studies deal with microcirculation in patients with IE, and so far none utilizing speckle contrast imaging and functional capillary density. The present study will contribute to the investigation of microcirculatory changes in IE and possibly to earlier diagnosis of the condition and/or of its severity and complications. The aim of the study is to evaluate the changes in microvascular bed of patients with both acute and subacute endocarditis by speckle contrast imaging and skin video-capillaroscopy.
ELDERL-IE is a multicenter national prospective observational study. The main objective is to describe geriatric characteristics (comorbidities, cognitive status, autonomy, nutritional status, balance and walking) in patients aged 75 years or older with infective endocarditis (IE). The secondary objectives are to assess the impact of geriatric features on the medico - surgical care and on morbidity and mortality at 3 months after the end of the hospitalization, and to describe the initial clinical presentation and diagnostic modalities in the IE elderly.
EMBOL-EI (Research Interest antiphospholipid antibody for embolic risk prediction in infective endocarditis) is a prospective cohort study with a biological collection. The main objective is: to re-evaluate the potential value of antiphospholipid (aPL) antibodies as predictors of embolic events in infective endocarditis (IE) in the light of the improved current knowledge on these aPL. The seconds objectives are: Other plasma biomarkers of hemostasis (coagulation activation markers: D-dimer fragment 1 + 2 of prothrombin; endothelial biomarkers: plasma levels of von Willebrand factor) will be taken into account in the analysis, and interest in predicting embolic risk, alone or in combination with aPL will be investigated.
The study aims at the comparative examination of pre-, intra- and post-operative release profiles of inflammatory and vasoactive mediators in patients undergoing heart valve surgery under cardiopulmonary bypass (CPB) due to either infectious endocarditis or degenerative valvular heart disease. Specific attention will focus on the distinction between mediator release associated with infection and that resulting from CPB. Concomitantly identification and characterization of infectious pathogens in the circulation and in valvular samples will be carried out, together with the search for resistance-coding transcripts.
The investigators conduct a prospective observational study on consecutive patients being admitted to a tertiary care-centre with infective endocarditis. The investigators' primary aim is to identify baseline clincal, laboratory and microbiological predictors of in-hospital events, mortality and 6-month mortality.
The purpose of this study is to assess the impact of 18-FDG positron emission tomography (PET)/computed tomography (CT) imaging in the management of patients with suspected or proven IE in detecting cardiac valve damages and other extracardiac complications. The study will evaluate whether this procedure can change the clinical decisions (treatments, valve surgery, patients' overall care) and modify the diagnosis of IE.
