INTRODUCTION: the incidence of invasive infections caused by pneumococcus (Streptococcus pneumoniae) has declined since generalized vaccination with pneumococcal conjugated vaccine, but it is still a prevalent pathogen in children. Amongst pneumococcal invasive infections, IE (infectious endocarditis) is rare, with an incidence between 1 and 7%. CASE REPORT: We describe the case of a previously healthy 4 year old boy, who had received one dose of 10-valent pneumococcal conjugate vaccine who presents with fever, a new heart murmur and heart failure...

A biofilm is an aggregate of microorganisms in which cells adhere to biological or non-biological surfaces and is responsible for various infectious diseases. Infections caused by Staphylococcus aureus , including pneumonia, endocarditis, and osteomyelitis, are often associated with colonization and biofilm formation. Although lipoteichoic acid (LTA) is involved in biofilm formation, the specific role of LTA is not clearly understood. In this study, we demonstrated that LTA released from Lactobacillus plantarum could inhibit S...

Whipple's disease is a chronic, rare, multisystemic, infectious entity, described for the first time in 1907. Its aetiological agent is the Gram-negative rod, Tropheryma whipplei, which was isolated for the first time in 2001 from a cardiac valve of a patient with endocarditis. We present the case of a 71-year-old man, who came into the emergency room complaining of anorexia, weakness, abdominal pain and diarrhoea with haematochezia and presented disseminated palpable purpuric lesions, predominantly in the lower limbs...

Infective endocarditis (IE) is a serious pathology with a poor prognosis, whose mortality has not changed significantly despite advances in its diagnosis and treatment in the last 30years. The diagnostic capacity of the modified Duke criteria in prosthetic endocarditis and/or devices does not exceed 50%, so new tools are necessary for the diagnosis of this entity in this context. The18 F-FDG PET/CTA combines a highly sensitive technique to detect inflammatory-infectious activity and a technique with high anatomical resolution to assess the structural lesions associated with endocarditis...

INTRODUCTION: Infectious endocarditis (IE) is a rare disease with a high mortality. In 2009, the European society of cardiology restricted antibiotic prophylaxis to a smaller number of cardiac conditions with very high risk for IE. Did these changes in the guidelines have an impact on the epidemiological and bacteriological profile of IE? AIM: The main aim of our work was to study the evolution of the microbiological profile of IE from 1991 to 2016. METHODS: We realized an analytic retrospective study comparing two groups: group 1 included patients admitted for a certain IE before September 2009 and group 2 those admitted after that date...

Marantic or nonbacterial thrombotic endocarditis is characterized for the presence of vegetations formed by a meshwork of fibrin and other cellular material similar a blood clot, without the presence of microorganisms. It is often related with tumors and chronic inflammatory states. We report a 49 years old female with a history of weight loss and asthenia, presenting with multiple cerebrovascular attacks and fever. Blood cultures were negative and the fever did not subside with antibiotic treatment. Trans esophageal echocardiogram showed a mitral valve vegetation and thickening of the free edge of both leaflets...

Aortic root replacement with a cryopreserved allograft aortic valve is effective for active infectious endocarditis and prosthetic valve endocarditis, especially with a perivalvular abscess, since an allograft seems to be resistant to infection by maintaining viable cells under the process of programmed freezing. From December 1998 to March 2017, aortic root replacement with allograft aortic valves were performed in 38 patients in the University of Tokyo. The in-hospital mortality was 18%, the 5-year survival rate was 68%, and the 5-year freedom rate of reoperation was 75%...

A 19-year-old male patient was admitted to our hospital after developing infectious endocarditis associated with methicillin-sensitive bovine Staphylococcus aureus septicemia. Brain magnetic resonance imaging confirmed occipital lobe cerebral bleeding. An echocardiogram showed severe mitral regurgitation with vegetation on the posterior mitral leaflet. We performed mitral valve replacement. However, a hepatic artery aneurysm and a ruptured splenic artery aneurysm was found on the 5th postoperative day and coil embolization was accordingly performed...

Communication technologies have invaded our daily lives. Several studies have assessed these technologies in the management of infectious diseases (mainly HIV). Weekly short text messages and real-time compliance monitoring assessed in HIV patients are both associated with higher compliance in low-income countries. Virtual consultations to monitor stable chronic HIV patients or tuberculosis treatment in high-income countries appear to be acceptable and efficient. Although assessed in small studies, virtual monitoring seems to reinforce the doctor-patient relationship and the relation between primary care settings and hospitals in various infectious diseases (endocarditis, urinary tract infection, skin and soft tissue infection, HIV, tuberculosis, hepatitis C)...

A young, still multimorbid woman aquires infectious endocarditis. Anamnestically severe non-adherence concerning medical advice is reported. Complete cure may only be achieved by performing surgical heart valve replacement, which implies lifelong scrupulous oral anticoagulation postoperatively. Discussion evolves within medical staff, whether surgery should be indicated or not.

This case highlights the importance of considering infectious etiology in the management of hemolytic anemia. Hemolytic anemia associated with infectious endocarditis is rare. Actinomyces endocarditis is a rare occurrence and is very challenging to diagnose given the challenges to culture the organism.

Staphylococcus aureus is still an important problem in clinical and therapeutic area, worldwide. In Italy, in recent years, methicillin resistance remained stable, yet considerably high, the percentage of strains of MRSA being around 40%. It was deemed interesting and timely to carry out a consensus conference using the RAND/UCLA method to collect the opinion of a group of experts in infectious diseases on the role of glycopeptides in the management of MRSA infections within several clinical scenarios and namely in pneumonia, bacteremia and endocarditis, joint replacement infections, skin and soft tissue infections, diabetic foot, abdominal infections and central nervous system infections...

Infectious endocarditis (IE) can be caused by various pathogens, from dominating agents such as viridans group streptococci and staphylococci to rare species that are less virulent and not typically considered to be pathogens. In this study, we have isolated a novel species from a patient with problem of IE which was genetically most closely related to 'Bergeyella cardium', a causative pathogen of IE first reported in Korea in 2015 as a new species of the genus Bergeyella, with a similarity of 98.8% in 16S rRNA sequences...

Infective endocarditis (IE) is an infectious disease that affects the endothelium of the large intrathoracic vessels, heart valves, and intra-cardiac foreign body material. A 20-year-old woman was admitted to the cardiology department with complaints of fever and palpitations. Transthoracic echocardiography revealed a bicuspid aortic valve, aortic root enlargement, and aortic coarctation. Transesophageal echocardiography revealed a bicuspid aortic valve, but there was no vegetation. Methicillin-sensitive Staphylococcus aureus was identified on a blood culture...

: Infective endocarditis is the manifestation of the endocardial involvement during a systemic infectious process.The prognosis of this condition is still dismal, and the mortality associated with it remains high despite improvement in antimicrobial treatment. Antibiotic prophylaxis is still recommended only in high-risk cases, that is, procedures at high risk for inducing systemic bacteremia.It is important to provide an educational prophylaxis consisting of sound hygienic recommendations for the cleansing of the oral cavity, the skin, genital-urinary, and gastrointestinal systems...
