<i>Background</i>. Infective endocarditis (IE) is a life-threatening disease. Its epidemiological profile has substantially changed in recent years although 1-year mortality is still high. Despite advances in medical therapy and surgical technique, there is still uncertainty on the best management and on the timing of surgical intervention. The objective of this review is to produce further insight into the short- and long-term outcomes of patients with IE, with a focus on those presenting cereb ...[more]

Project description:Severe neurological complications following infective endocarditis remain a major problem with high mortality rate. The long-term neurological consequences following infective endocarditis remain uncertain. Otherwise, neurosurgeries could be performed after these complications; however, few clinical series have reported the results. Therefore, we utilized a large, nationwide database to unveil the long-term mortality and neurosurgical outcome following infective endocarditis. We included patients with a first-time discharge diagnosis of infective endocarditis between January 2001 and December 2013 during hospitalization. Patients were further divided into subgroups consisting of neurological complications under neurosurgical treatment and complications under non-neurosurgical treatment. Long-term result of symptomatic neurological complications after infective endocarditis and all-cause mortality after different kinds of neurosurgeries were analyzed. There were 16,495 patients with infective endocarditis included in this study. Symptomatic neurological complications occurred in 1,035 (6.27%) patients, of which 279 (26.96%) accepted neurosurgical procedures. Annual incidence of neurological complications gradually increased from 3.6% to 7.4% (P?<?0.001). The mortality rate among these patients was higher than that among patients without complications (48.5% vs. 46.1%, P?=?0.012, increased from 20% initially to nearly 50% over the 5-year follow-up). However, neurosurgery had no effect on the long-term mortality rate (50.9% vs. 47.6%, P?=?0.451). Incidence of neurological complications post-infective endocarditis is increasing, and patients with these complications have higher mortality rates than patients without. Neurosurgery in these populations was not associated with higher long-term mortality. Therefore, it should not be ruled out as an option for those with neurological complications.

Project description:ObjectivesSymptomatic neurological complications (NC) are a major cause of mortality in infective endocarditis (IE) but the impact of asymptomatic complications is unknown. We aimed to assess the impact of asymptomatic NC (AsNC) on the management and prognosis of IE.MethodsFrom the database of cases collected for a population-based study on IE, we selected 283 patients with definite left-sided IE who had undergone at least one neuroimaging procedure (cerebral CT scan and/or MRI) performed as part of initial evaluation.ResultsAmong those 283 patients, 100 had symptomatic neurological complications (SNC) prior to the investigation, 35 had an asymptomatic neurological complications (AsNC), and 148 had a normal cerebral imaging (NoNC). The rate of valve surgery was 43% in the 100 patients with SNC, 77% in the 35 with AsNC, and 54% in the 148 with NoNC (p<0.001). In-hospital mortality was 42% in patients with SNC, 8.6% in patients with AsNC, and 16.9% in patients with NoNC (p<0.001). Among the 135 patients with NC, 95 had an indication for valve surgery (71%), which was performed in 70 of them (mortality 20%) and not performed in 25 (mortality 68%). In a multivariate adjusted analysis of the 135 patients with NC, age, renal failure, septic shock, and IE caused by S. aureus were independently associated with in-hospital and 1-year mortality. In addition SNC was an independent predictor of 1-year mortality.ConclusionsThe presence of NC was associated with a poorer prognosis when symptomatic. Patients with AsNC had the highest rate of valve surgery and the lowest mortality rate, which suggests a protective role of surgery guided by systematic neuroimaging results.

Project description:Background: The interplay between cancer and IE has become of increasing interest. This study sought to assess the prevalence, baseline characteristics, management, and outcomes of IE cancer patients in the ESC EORP EURO-ENDO registry. Methods: Three thousand and eighty-five patients with IE were identified based on the ESC 2015 criteria. Three hundred and fifty-nine (11.6%) IE cancer patients were compared to 2,726 (88.4%) cancer-free IE patients. Results: In cancer patients, IE was mostly community-acquired (74.8%). The most frequently identified microorganisms were S. aureus (25.4%) and Enterococci (23.8%). The most frequent complications were acute renal failure (25.9%), embolic events (21.7%) and congestive heart failure (18.1%). Theoretical indication for cardiac surgery was not significantly different between groups (65.5 vs. 69.8%, P = 0.091), but was effectively less performed when indicated in IE patients with cancer (65.5 vs. 75.0%, P = 0.002). Compared to cancer-free IE patients, in-hospital and 1-year mortality occurred in 23.4 vs. 16.1%, P = 0.006, and 18.0 vs. 10.2%; P < 0.001, respectively. In IE cancer patients, predictors of mortality by multivariate analysis were creatinine > 2 mg/dL, congestive heart failure and unperformed cardiac surgery (when indicated). Conclusions: Cancer in IE patients is common and associated with a worse outcome. This large, observational cohort provides new insights concerning the contemporary profile, management, and clinical outcomes of IE cancer patients across a wide range of countries.

Project description:BackgroundEffects of malnutrition on patients with infective endocarditis (IE) have not been fully studied. Because malnutrition is associated with poor health, we hypothesized that among patients with IE, those with malnutrition would have more negative in-hospital outcomes.MethodsThe National Inpatient Sample was used to identify adults ≥18 years old with IE. We compared outcomes of in-hospital mortality, morbidity, valvular interventions, and utilization of resources between individuals with and without malnutrition.Results11,939 adults ≥18 years were hospitalized with IE, 2035 had a secondary diagnosis for malnutrition. There were no significant differences in age (mean age ± SEM: 55.6 ± 1.0 vs 54.3 ± 0.4 years, P = .21) or sex (female: 36.7%; 743/2,035 vs 37.5%; 3,717/9,904, P = .69) in patients with and without malnutrition. Patients with malnutrition had more comorbidities (Charlson comorbidity score ≥3: 36%; 732/2,035 vs 30.7%; 3,040/9,904, P = .04). Despite similar adjusted in-hospital mortality (adjusted odds ratio [aOR], 1.4; 95% CI, 0.8-1.5; P = .23), malnourished patients were more likely to develop sepsis (aOR, 1.7; 95% CI, 1.2-2.4; P < .01) and had higher odds of mitral-valve (aOR, 1.7; 95% CI, 1.2-2.4; P < .01) repairs/replacements. Patients with malnutrition also had increased lengths of stay (adjusted mean difference [aMD], 4.7 days; 95% CI, 2.9-6.5 days; P < .01) and hospital charges (aMD, $36,052; 95% CI, $14,935-$57,168; P < .01).ConclusionsPatients with malnutrition and IE are at risk for high morbidity, valvular repairs/replacements, and use of hospital resources.

Project description:Infective endocarditis (IE) is a rare, life-threatening disease that has long-lasting effects even among patients who survive and are cured. IE disproportionately affects those with underlying structural heart disease and is increasingly associated with health care contact, particularly in patients who have intravascular prosthetic material. In the setting of bacteraemia with a pathogenic organism, an infected vegetation may form as the end result of complex interactions between invading microorganisms and the host immune system. Once established, IE can involve almost any organ system in the body. The diagnosis of IE may be difficult to establish and a strategy that combines clinical, microbiological and echocardiography results has been codified in the modified Duke criteria. In cases of blood culture-negative IE, the diagnosis may be especially challenging, and novel microbiological and imaging techniques have been developed to establish its presence. Once diagnosed, IE is best managed by a multidisciplinary team with expertise in infectious diseases, cardiology and cardiac surgery. Antibiotic prophylaxis for the prevention of IE remains controversial. Efforts to develop a vaccine that targets common bacterial causes of IE are ongoing, but have not yet yielded a commercially available product.

Project description:Clinical manifestations of infective endocarditis (IE) can be highly non-specific. Our objective was to describe the clinical characteristics of patients initially referred to a department of internal medicine for a diagnostic work-up, and eventually diagnosed with IE. We retrospectively retrieved adult patients admitted to the department of internal medicine at Lille University Hospital between 2004 and 2015 who fulfilled Duke Classification criteria for definite IE. Thirty-five patients were included. The most frequently involved bacteria were non-hemolytic streptococci. Most patients presented with various systemic, cardiac, embolic, rheumatic, and immunological findings, with no sign or symptom displaying high sensitivity. The first transthoracic echocardiogram was negative in 42% of patients. Furthermore, definite diagnosis required performing at least 2 transesophageal examinations in 24% of patients. We observed a trend towards decreased survival in the subgroup of patients in whom the delay between onset of symptoms and diagnosis was >30 days. In conclusion, patients who are initially referred to internal medicine for a diagnosis work-up and who are ultimately diagnosed with IE have non-specific symptoms and a high percentage of initial normal echocardiography. Those patients require prolonged echocardiographic monitoring as a prolonged delay in diagnosis is associated with poorer outcomes such as death.

Project description:BackgroundInfective endocarditis (IE) remains a severe disease with a high mortality rate. Therefore, guidelines encourage the setup of a multidisciplinary group in reference centers. The present study evaluated the impact of this "Endocarditis Team" (ET).MethodsWe conducted a monocentric observational study at Strasbourg University Hospital, Strasbourg, France, between 2012 and 2017. The primary end point was in-hospital mortality. Secondary end points were 6-month and 1-year mortality, surgery rate, time to surgical procedure, duration of effective antibiotic therapy, length of in-hospital stay, and sequelae. We also assessed predictors of in-hospital mortality.ResultsWe analyzed 391 episodes of IE. In the post-ET period, there was a nonsignificant decrease in in-hospital mortality (20.3% vs 14.7%, respectively; P = .27) and sequelae, along with a significant reduction in time to surgery (16.4 vs 10.3 days, respectively; P = .049), duration of antibiotic therapy (55.2 vs 47.2 days, respectively; P < .001), and length of in-hospital stay (40.6 vs 31.9 days, respectively; P < .01). In a multivariate analysis, the post-ET period was positively associated with survival (odds ratio, 0.45; 95% confidence interval, 0.20-0.96; P = .048).ConclusionsThis multidisciplinary approach exerted a positive impact on the management of IE and should be considered in all hospitals managing IE.

Project description:BackgroundCerebral mycotic aneurysms represent a rare but life-threatening complication of infective endocarditis (IE), with high mortality rate when ruptured. Due to the lack of randomized controlled trials, management of infectious aneurysms complicating endocarditis remains a controversial topic.Case summaryWe describe a case of Streptococcus salivarius bicuspid aortic and mitral valve endocarditis with concurrent spontaneous mycotic aneurysm rupture and acute subarachnoid haemorrhage (SAH). A 40-year-old man with history of intravenous drug abuse presented to our emergency department with altered mental status and dyspnoea. Echocardiography documented large vegetations on a bicuspid aortic valve and on the mitral valve, causing acute severe aortic and mitral regurgitation. Brain computed tomography imaging documented a ruptured fusiform aneurysm in a distal branch of the right middle cerebral artery causing acute SAH and acute obstructive hydrocephalus. An external ventricular drain was emergently placed and endovascular embolization of the aneurysm was achieved with deployment of six coils. Blood cultures grew S. salivarius and antibiotic therapy according to microbiological sensitivities was administered. Hospital stay was complicated by acute heart failure, ST-elevation myocardial infarction, conduction disturbances, cerebral vasospasm, recurrent mycotic aneurysm rupture, and death.DiscussionClinicians should be mindful of the rare, potentially severe complication of IE with cerebral mycotic aneurysms to enable prompt treatment. Generally, central nervous system procedures are performed prior to cardiac surgical management of IE, since cardiopulmonary bypass may exacerbate cerebral haemorrhage, ischaemic damage, and oedema in areas of blood-brain barrier disruption. A multidisciplinary collaboration is crucial for optimal patient management.
