Foram estudados 300 episódios de endocardite infecciosa (EI) em 288 pacientes acompanhados no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, no período de outubro de 1978 a agosto de 1986, com o intuito de avaliar a probabilidade de óbito e assim identificar os pacientes sob maior risco de evolução desfavorável. As idades dos pacientes variaram entre 0,2 a 78 (média de 30, desvio padrão de 16,06) anos, correspondentes a pacientes do sexo masculino em 185 (62%) episódios e feminino em 115 (38%).

Abstract:

Introduction: Advances in modern medicine have enabled early detection of infective diagnosis through blood cultures and echocardiography, which have been standardized by the widely accepted Modified Duke Criteria and have enabled rapid administration of antibiotics. As a consequence, the well-discussed and often variable clinical findings have become less common and have relegated to minor criteria in diagnosis. Fever is the single most common presenting symptom, whereas more specific signs such as petechiae may be seen in only 20-40% of patients. Even more rare are the pathognomonic Janeway

Abstract:

Introduction: Bacterial-platelet-fibrin complexes (vegetations), form on cardiac valves in infective endocarditis and are associated with increased morbidity and mortality. Although the mechanisms of bacterium-platelet adhesion, platelet activation and aggregation that are likely to contribute to vegetation formation have been identified, experimental conditions employed in these studies do not accurately reflect bacterial growth in the human vasculature. In addition, the contribution of host genetic factors such as platelet receptor polymorphisms to the pathogenesis of infective endocarditis

Introduction. It is known that infections may occur after urological instrumentation, as some patients develop infective symptoms.

Abstract:

Streptococcus sanguinis is the second most common causative agent of bacterial infective endocarditis (IE). Risk of S. sanguinis IE is dependent on pre-disposing damage to the heart valve endothelium, which results in deposition of clotting factors for formation of a sterile thrombus (referred to as vegetation). Despite medical advances, high mortality and morbidity rates persist. Molecular characterization of S. sanguinis virulence determinants may enable development of prevention methods.

Bartonella bacilliformis was isolated in blood cultures, defining the diagnosis of infective endocarditis using Duke’s criteria. Subsequently, the patient developed clinical and laboratory features compatible with antineutrophil cytoplasmic antibody-associated vasculitis. This case pr

Background: Infective endocarditis (IE) is an infection of the innermost layer of the heart.

The evidence base for the guidelines is limited. Specifically, the risk of IE in a population-based cohort of patients with congenital heart disease (CHD) has not been reported.

S. aureus causes a variety of infections including superficial skin lesions, toxic shock syndrome, and infective endocarditis (IE). There are 100,000 cases of IE each year in the United States. IE is a life threatening infection of native/prosthetic valves and the lining of the heart. It is characterized by the formation of vegetations, “cauliflower-like” structures composed of bacteria and host factors.

Abstract:

Streptococci resident in the oral cavity have been linked to infective endocarditis (IE). While viridans streptococci are commonly studied and associated with IE, less research has been focused on Streptococcus pneumoniae. Two-component systems (TCSs), consisting of a histidine kinase (HK) protein and response regulator (RR) protein, are bacterial signaling systems that may mediate S. pneumoniae TIGR4 strain virulence in IE. To test this hypothesis, TCS RR mutants of TIGR4 were examined in vivo through use of rabbit models. There were 14 RR proteins identified and 13 RR mutants synthesized

Staphylococcus aureus is the leading cause of infective endocarditis in the United States. Infective endocarditis (IE) is defined as an infection of the endocardium, typically involving the heart valves. The hallmark features of IE are vegetations. Vegetations are cauliflower-like, stratified biofilms of bacteria and host factors that develop on the valve leaflets of the heart. The mechanisms of how vegetations form are not well understood, and as a consequence the bacterial factors that are important for development of IE are not well defined.

Abstract:

O objetivo desse estudo foi avaliar os efeitos da administração prévia de antibiótico na incidência de complicações infecciosas em procedimentos de estimulação cardíaca artificial. Os pacientes foram selecionados em um estudo duplo-cego e randomizado (1:1). Grupo I Cefazolina (1,0g dose única) versus grupo II placebo. O comitê de segurança interrompeu o estudo após a inclusão de 649 pacientes devido à diferença entre os grupos (group I 314; grupo II 335 pacientes) em favor do uso de antibiótico: 2 infectados (0,63%) versus 11 infectados no grupo placebo (3,28%); p=0,016. Marcadores identifi

Abstract:

La fièvre Q se traduit par de graves conséquences obstétricales chez la femme enceinte. La voie principale de la contamination humaine par Coxiella burnetii, l’agent de la fièvre Q, est constituée des aérosols provenant des placentas d’animaux infectés. La nature des cellules placentaires cibles de C. burnetii reste totalement inconnue. J’ai montré que C. burnetii infecte les trophoblastes des lignées BeWo et JEG et que les bactéries se répliquent fortement dans les cellules BeWo et survivent dans les cellules JEG. Une analyse par microarray montre que C. burnetii induit une réponse inflammato

Abstract:

BACKGROUND: Infective endocarditis (IE) is an infectious disease, most often bacterial in etiology, which affects the endocardial tissue layer of the heart. Despite advances in diagnostic technology, surgical technique, and antimicrobial therapy, IE remains a high-mortality disease. OBJECTIVE: This is a proposed quality improvement initiative for the Boston Medical Center (BMC) inpatient medicine service. The initiative aims to identify predictors of mortality in patients with IE, and then use the predictors to create a mortality risk-assessment checklist. The checklist will serve as a clini

Abstract:

碩士<br>國立臺灣大學<br>口腔生物科學研究所<br>106<br>Infective endocarditis (IE) is an infectious disease of the cardiovascular system, and carries a high recurrence and mortality rate. Streptococcus mutans, a member of viridans streptococci, is a commensal in the oral cavity and also one of major opportunistic pathogen for causing IE. Escaping immune surveillance and forming biofilm are two determining virulent factors for bacteria to cause IE. Our previous reports demonstrated that one S. mutans protein, AtlA, not only plays the role in enhancing bacterial resistance against neutrophil killing through bindin
