Filter by:Infectious endocarditis (IE) and other severe infections are well-known to induce significant changes in the immune response including immune functionality in a considerable number of affected patients. In fact, numerous patients with IE develop a persistent functional immunological phenotype that can best be characterized by a profound anti-inflammation and/or functional anergy. This was previously referred to as "injury-associated immunosuppression (IAI)" by Pfortmüller et al., published in Intensive Care Medicine Experimental 2017. IAI can be assessed by measurement of cellular (functional) markers. Persistence of IAI is associated with prolonged ICU length of stay, increased secondary infection rates, and death. Immunomodulation to reverse IAI was shown beneficial in immunostimulatory (randomized controlled) clinical trials. CytoSorb® treatment is currently used as standard of care in some institutions in surgically treated IE patients. The investigators aim to investigate two accepted treatment protocols and aim to explore whether adsorption with a cytokine adsorption filter can increase immune competence in treated individuals.
Infective endocarditis (IE) is associated with an overall in-hospital mortality rate of 15-25% and a high incidence of embolic events (20-50%). Leading causes of mortality are heart failure (HF) resulting from valve dysfunction, and stroke caused by vegetation embolization. The rate of symptomatic embolic events occurring after antibiotic initiation is around 15%. Valve surgery benefit has been clearly demonstrated in patients with periannular complications and moderate to severe HF resulting from acute valve regurgitation. The timing of surgery to prevent embolism is critical since the risk of new embolic event is highest during the first weeks of antibiotic treatment. The primary objective is to compare clinical outcomes of Early Valve Surgery (as soon as possible within 72 hours of randomization) with those of a conventional management based on current guidelines in patients with native left-sided IE and high risk of embolism. 208 patients (104 patients per arm) will be included in a national multicenter (19 centers) prospective randomized open blinded end-point (PROBE) sequential superiority trial.
Develop and implementation an addiction recovery support program for cardiac surgery patients admitted with a diagnosis of infective endocarditis secondary to IV drug addiction.
PET scanning (positron emission tomography) is a well-established technique used to identify areas of interest within the body. It involves injecting a radioactive tracer which highlights abnormal areas. It has recently been combined with CT (computed tomography) and MRI (magnetic resonance imaging) scanning to more accurately identify abnormalities within the heart. Infective endocarditis (infection of the heart valves or lining of the heart) and device infection (where a pacemaker device or wire becomes infected) are of particular interest in this area. The study makes use of hybrid PET/MR scanning using a designated scanner which enables PET scanning combined with MRI scanning. PET scanning combined with CT scanning will be used instead for patients who aren't able to undergo MRI scanning. This will allow abnormal areas within the heart in these conditions to be characterised, alongside treatment regimens, in a way which hasn't been done before. All participants will undergo PET scanning, where a radioactive tracer is injected into a vein before the scan. The radioactive substance only lasts for a short time, passed out of the body in urine. Patients with infective endocarditis involving their own heart valve will undergo an MRI scan as part of the PET scan. Patients with infective endocarditis involving a metal or prosthetic heart valve and also patients who have pacemaker infections, instead of an MRI, will have a CT scan. The reason for this is that CT is better for looking at metal and prosthetic heart valves and patients with pacemakers can't have MRI scans because the strong magnet in the scanner can affect the pacemaker. The scan will be performed twice; once before treatment and once after treatment has been established. If successful, this imaging method will play a key role in diagnosing, quantifying and monitoring these conditions.
The objective of this observatory is to provide a national database of infective endocarditis, informed by all volunteer centers, using a standardized case report forms. Such an observatory will describe the clinical profile, microbiological, therapeutic and evolving of infective endocarditis (IE); analyze the risk factors for the disease and its prognosis factors of evolution; describe management practices; evaluate and compare in the real drug treatment strategies (including antibiotics) and surgical.
Infectious endocarditis (IE) is the localization and proliferation of blood-borne germs in the endocardium. It remains a complicated disease to manage due to its low incidence, diagnostic difficulties, the change in epidemiology in recent decades and high mortality rates. The annual incidence is estimated at 3-10 cases per 100,000 people. The epidemiology of AR has changed significantly in recent years due to new risk factors. Indeed, the frequency of rheumatic heart disease, which was the first predisposing factor, decreased markedly in the industrialized countries, replaced by new predisposing factors: the presence of valvular prostheses or intracardiac materials (the risk of AR is multiplied by 50 Compared with the general population), hemodialysis, nosocomial infections, immunosuppression, increased use of injectable treatments and, above all, an aging population with an increase in degenerative diseases such as aortic stenosis and l Mitral insufficiency. The diagnosis of IA is based on DUKE criteria. But the clinical presentation is sometimes atypical especially in case of infection on prosthesis where the diagnosis is based mainly on the results of the blood cultures and the ultrasound data. The lesions visualized in ultrasound are: vegetations, abscesses, pseudo-aneurysms and fistulas constituting the degenerated abscess evolution, the perforation of the cusps of the native valve or the bioprosthesis giving rise to a jet of Eccentric regurgitation. The evolution of endocarditis and its prognosis vary according to many factors: the type of germ responsible, the precocity of the diagnosis, the existence of a complication, the site of occurrence. These complications of endocarditis are frequent, sometimes revealing. EI is complicated by heart failure, atrioventricular conduction disorders, peri-vascular abscesses, embolic, neurological, renal and septic complications. Despite improvements in diagnosis and therapeutic methods, diagnosis is sometimes difficult, management remains very complicated and morbidity and mortality remain high. Studies are still needed to study the prognosis and to determine the predictive factors for hospital mortality and long-term mortality.
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.
Infective endocarditis (IE) is defined as a bacterial infection of the endocardium (inner surface of the heart), which may include one or more heart valves. Epidemiologic pattern has changed during the last 20 years whereas the incidence was unchanged. However, the mortality increase despite recent diagnosis and therapeutic advances. Only few investigations consider the prognostic and the therapeutic medical care according to the clinical care pathway. In fact, 3 situations are observed: (i) patient for whom diagnosis and medical care are realized in a referent center with cardiac surgery, (ii) patients secondary addressed to a referent center with cardiac surgery, (iii) patients for which the totality medical care are performed in non-referent health center. In addition, epidemiologic studies concern only a part of IE, not including most of the time the patients hospitalized in non-referent center. The aim of the study was to determine the prognosis of threated patients according to the clinical care pathway. Secondary objectives was (i) to evaluate the application of European recommendations concerning trans-oesophageal echocardiogram (TOE), antibiotic treatment and surgical practice, (ii) to compare the epidemiologic profile according to the type of center. For this, 300 patients addressed in the 22 French participating centers for a possible or certain IE according to Duke Criteria were prospectively included during 3 years. Patient data (clinical, demographical, biological, microbiological, echocardiographic and evolutive data) were collected at the admission, during hospitalization, at discharge and one-year follow up.
Infective endocarditis (IE) is a serious infection with a significant burden for patients and hospitals (in France, median length of hospital stay = 43 days), partly due to the long duration of intravenous (IV) antibacterial treatment recommended by international guidelines, between 4 and 6 weeks in most situations. A recent survey of practices regarding the management of IE in France showed that a switch from IV to oral antibiotics is feasible, when patients with left-sided Staphylococcus IE are stable after an initial course of IV antibiotic treatment, with or without valvular surgery. These practices have not been associated with unfavourable outcome, while significantly reducing the duration and cost of hospitalization, the risk of nosocomial infection, and patients' discomfort. There has been no randomized controlled trial (RCT) in the field of IE over the last 20 years; current guidelines are mostly based on expert advice, in vitro studies, animal experiments, or clinical studies performed before the 90's. The RODEO 1 project is an unprecedented opportunity to bring back evidence-based medicine in the field of IE. Most experts acknowledge that the pharmacological PK/PD characteristics of antibiotics such as fluoroquinolones and rifampicin allow a high level of efficacy in the treatment of IE when orally administrated after an IV period of induction. It's needed to conduct RCTs that clearly demonstrate the clinical non-inferiority of this strategy for multisusceptible staphylococci with a benefit regarding costs. The RODEO 1 project corresponds to one pragmatic trial assessing the impact of a switch strategy, making it a comparative effectiveness trial that should be able to feed the next revision of IE international guidelines and to change practices in IE management.
