Effect of antibiotic treatment on vegetation size and complication rate in infective endocarditis
1997
Background: Infective endocarditis is associated with significant morbidity and mortality, with valvular destruction, and with congestive heart failure. Embolic events are more common in patients with echocardiographically discernible vegetations, especially when vegetations are >10 mm in diameter. Hypothesis: The objective of the study was to follow vegetation morphology during native valve endocarditis, to compare it with the clinical course and antibiotic treatment chosen, and to evaluate whether the impact on vegetation size and complication rate of antibiotic regimens differed in patients with positive and negative blood cultures. Methods: The effect of different antibiotic regimes on …
Portraying infective endocarditis
2019
Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients …
Staphylococcal Biofilms:Challenges in the Discovery of Novel Antiinfective Agents
2011
Staphylococci can induce a wide spectrum of infectious diseases that are associated with remarkable morbidity and mortality [1]. In fact, community and hospital-acquired methicillin resistant Staphylococcus aureus (MRSA) is a major health problem that has created a pressing need for novel therapeutic options [2]. Importantly, pathogenic staphylococci have not only an amazing ability to acquire resistance to antibiotics, but also to form biofilms, bacterial communities that grow on surfaces and are surrounded by a self-produced polymer matrix. This latter characteristic is likely the most important virulence factor of staphylococci in the development of the chronic form of infectious disease…
Impact of systematic whole-body 18F-fluorodeoxyglucose PET/CT on the management of patients suspected of infective endocarditis: the prospective mult…
2021
AbstractBackgroundDiagnostic and patients’ management modifications induced by whole-body 18F-FDG-PET/CT had not been evaluated so far in prosthetic valve (PV) or native valve (NV) infective endocarditis (IE)-suspected patients.MethodsIn sum, 140 consecutive patients in 8 tertiary care hospitals underwent 18F-FDG-PET/CT. ESC-2015-modified Duke criteria and patients’ management plan were established jointly by 2 experts before 18F-FDG-PET/CT. The same experts reestablished Duke classification and patients’ management plan immediately after qualitative interpretation of 18F-FDG-PET/CT. A 6-month final Duke classification was established.ResultsAmong the 70 PV and 70 NV patients, 34 and 46 wer…
