Methods: In total, 221 episodes of definite endocarditis were studied (2004-2009). We compared the clinical, laboratory, and echocardiography characteristics and the survival rates of patients with culture-negative and culture-positive endocarditis. Survival after hospital discharge was evaluated using the Kaplan-Meier method and coefficient of mortality comparisons. Results: Culture-negative endocarditis occurred in 51/221 (23.1%) episodes. Compared with the culture-positive endocarditis patients, the time elapsed between admission and initiation of antibiotic therapy was longer in patients with culture-negative endocarditis (p < 0.001), and these patients also had lower C-reactive protein levels at admission (p < 0.001). In-hospital mortality rates were not different between culture-negative and culture-positive patients. After hospital discharge, there was also no significant difference between groups in survival curves (p = 0.471). Severe sepsis (adjusted prevalence ratio 3.32, p = 0.010) and diabetes mellitus (adjusted prevalence ratio 2.32, p = 0.009) were independently associated with in-hospital death in culture-negative patients. Conclusions: Culture-negative endocarditis patients presented with lower levels of C-reactive protein at admission and required more time for initiation of antibiotic therapy, although there was no difference in in-hospital mortality or long-term survival between culture-negative and culture-positive endocarditis patients. Diabetes mellitus and severe sepsis were associated with in-hospital death in patients with culture-negative endocarditis. (C) 2014 The Authors.
- Bartonella spp. and Coxiella burnetii Associated with Community-Acquired, Culture-Negative Endocarditis, Brazil(2015) SICILIANO, Rinaldo Focaccia; CASTELLI, Jussara Bianchi; MANSUR, Alfredo Jose; SANTOS, Fabiana Pereira dos; COLOMBO, Silvia; NASCIMENTO, Elvira Mendes do; PADDOCK, Christopher D.; BRASIL, Roosecelis Araujo; VELHO, Paulo Eduardo Neves Ferreira; DRUMMOND, Marina Rovani; GRINBERG, Max; STRABELLI, Tania Mara VarejaoWe evaluated culture-negative, community-acquired endocarditis by using indirect immunofluorescent assays and molecular analyses for Bartonella spp. and Coxiella burnetii and found a prevalence of 19.6% and 7.8%, respectively. Our findings reinforce the need to study these organisms in patients with culture-negative, community-acquired endocarditis, especially B. henselae in cat owners.
- The Role of F-18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in the Diagnosis of Left-sided Endocarditis: Native vs Prosthetic Valves Endocarditis(2020) CAMARGO, Raphael Abegao de; BITENCOURT, Marcio Sommer; MENEGHETTI, Jose Claudio; JR, Jose Soares; GONCALVES, Luis Fernando Tonello; BUCHPIGUEL, Carlos Alberto; PAIXAO, Milena Ribeiro; FELICIO, Marilia Francesconi; SOEIRO, Alexandre de Matos; STRABELLI, Tania Mara Varejao; MANSUR, Alfredo Jose; TARASOUTCHI, Flavio; JR, Mucio Tavares de Oliveira; CASTELLI, Jussara Bianchi; GUALANDRO, Danielle Menosi; POCEBON, Lucas Zoboli; BLANKSTEIN, Ron; ALAVI, Abass; MOORE, John Edmund; MILLAR, Beverley Cherie; SICILIANO, Rinaldo FocacciaBackground: F-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG-PET/CT) has emerged as a useful diagnostic tool for suspected infective endocarditis (IE) in patients with prosthetic valves or implantable devices. However, there is limited evidence regarding use of F-18-FDG-PET/CT for the diagnosis of native valve endocarditis (NVE). Methods: Between 2014 and 2017, 303 episodes of left-sided suspected IE (188 prosthetic valves/ascending aortic prosthesis and 115 native valves) were studied. F-18-FDG-PET/CT accuracy was determined in the subgroups of patients with NVE and prosthetic valve endocarditis (PVE)/ascending aortic prosthesis infection (AAPI). Associations between inflammatory infiltrate patterns and F-18-FDG-PET/CT uptake were investigated in an exploratory ad hoc histological analysis. Results: Among 188 patients with PVE/AAPI, the sensitivity, specificity, and positive and negative predictive values of F-18-FDG-PET/CT focal uptake were 93%, 90%, 89%, and 94%, respectively, while among 115 patients with NVE, the corresponding values were 22%, 100%, 100%, and 66%. The inclusion of abnormal F-18-FDG cardiac uptake as a major criterion at admission enabled a recategorization of 76% (47/62) of PVE/AAPI cases initially classified as ""possible"" to ""definite"" IE. In the histopathological analysis, a predominance of polymorphonuclear cell inflammatory infiltrate and a reduced extent of fibrosis were observed in the PVE group only. Conclusions: Use of F-18-FDG-PET/CT at the initial presentation of patients with suspected PVE increases the diagnostic capability of the modified Duke criteria. In patients who present with suspected NVE, the use of F-18-FDG-PET/CT is less accurate and could only be considered a complementary diagnostic tool for a specific population of patients with NVE.
