RATIONALE: Endocarditis with Abiotrophia defectiva represents 4.3% to 6% of all streptococcal endocarditis. The article presents diagnosis issues and the complexity of the treatment. PATIENT CONCERNS: We present the case of a female white patient, aged 26 years, who developed infectious endocarditis caused by A defectiva, in the last trimester of pregnancy, a biofilm-related infection associated with the presence of fixed braces. DIAGNOSES: The diagnosis of infectious endocarditis was confirmed by the cardiac ultrasound examination that revealed a voluminous vegetation on the mitral valve, and acute mitral regurgitation caused by chordae tendinae rupture, and also by isolating Abiotrophia defectiva from two positive blood cultures...

BACKGROUND: Fistula to the pericardial cavity is a very rare complication of perivalvular abscess during infective endocarditis, with Staphylococcus aureus being the most commonly associated microorganism. METHODS: We report a fatal septic shock due to a mitral endocarditis revealed by a myocardial abscess fistulised toward the pericardial cavity. RESULTS: A 66-year-old female without previous valvular disease was admitted to intensive care for severe sepsis...

Infective endocarditis (IE) is a rare condition which is associated with considerable morbidity and mortality. Almost 100 years ago, the links between endocarditis and procedures, particularly dental procedures, were postulated. Over 50 years ago the first guidelines recommending antibiotic prophylaxis (AP), with the aim of preventing IE developing after procedures, were proposed. However, there has only ever been circumstantial evidence in humans that AP prevents IE. The rarity of IE has made a randomised controlled clinical trial impractical to date...

PURPOSE: To review the epidemiology of Staphylococcus aureus bacteraemia (SAB) and endocarditis (SAE), and discuss the short- and long-term outcome.  Materials and methods: A literature review of the epidemiology of SAB and SAE. RESULTS: The reported incidence of SAB in Western countries is 16-41/100,000 person-years. Increasing incidence has been observed in many regions, in Iceland by 27% during 1995-2008. The increase is believed to depend on changes in population risk factors and possibly better and more frequent utilization of diagnostic procedures...

A 78-year-old man who had undergone aortic valve and ascending aorta replacements presented with fever and was referred to our hospital. Blood culture revealed Gram-positive cocci, thus antibiotic therapy was started. Brain magnetic resonance imaging showed fresh cerebral infarction without cerebral haemorrhage or mycotic aneurysm. Transoesophageal echocardiogram revealed a vegetation that was attached to the right coronary cusp. The patient underwent successful aortic valve neocuspidization using glutaraldehyde-treated bovine pericardium...

  An increasing number of invasive infections due to Streptococcus agalactiae in non-pregnant adults have been reported. We report a case of infective endocarditis complicated by intraventricular abscesses, pericarditis, and mycotic aneurysm due to S. agalactiae belonging to ST681 with a capsular serotype VI in a diabetic woman. The patient also had a myocardial infarction and was treated with percutaneous coronary intervention, pericardiocentesis, and 6 weeks of antibiotic treatment. Invasive infections due to serotype VI S...

Aorto-atrial fistulas are a relatively rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria. Aorto-atrial fistulas are most often the result of an underlying condition concerning the cardiac structures. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature. Secondary causes incite local deterioration of cardiac wall integrity leading to formation of fistulous connections, while iatrogenic causes are more traumatic in nature...

The term "mycotic aneurysm" was first used by Osler in 1882 to describe a mushroom-shaped aneurysm in subacute bacterial endocarditis. Mycotic aneurysms account for only 2.6% of all aneurysms of the aorta. Rarer still are anaerobic infections secondary to organisms such as Clostridium septicum, which results in emphysematous aortitis. The vast majority of emphysematous aortic infections occur as a result of instrumentation; however, in this case we present an infection de novo. A 75-year-old male presented with a 2-week history of progressive fatigue and chest pain that then developed into constitutional symptoms...

Dentistry plays an important role in managing the antibiotic resistance problem. Guidelines for the use of antibiotics for prevention of endocarditis, prosthetic joint infections and other medical conditions have changed frequently. Unfortunately, the original guidelines and subsequent changes were often made through consensus opinions and not evidence based. Clinical decisions on the use of antibiotics must be made on the basis of the scientific evidence with knowledge of the most current guidelines and indications...

REVIEW
Meiyan Jiang, Takatoshi Karasawa, Peter S Steyger
Aminoglycoside antibiotics are used as prophylaxis, or urgent treatment, for many life-threatening bacterial infections, including tuberculosis, sepsis, respiratory infections in cystic fibrosis, complex urinary tract infections and endocarditis. Although aminoglycosides are clinically-essential antibiotics, the mechanisms underlying their selective toxicity to the kidney and inner ear continue to be unraveled despite more than 70 years of investigation. The following mechanisms each contribute to aminoglycoside-induced toxicity after systemic administration: (1) drug trafficking across endothelial and epithelial barrier layers; (2) sensory cell uptake of these drugs; and (3) disruption of intracellular physiological pathways...

Daptomycin is a cyclic lipopeptide antibiotic used for the treatment of Gram-positive infections including complicated skin and skin structure infections, right-sided infective endocarditis, bacteraemia, meningitis, sepsis and urinary tract infections. Daptomycin has distinct mechanisms of action, disrupting multiple aspects of cell membrane function and inhibiting protein, DNA and RNA synthesis. Although daptomycin resistance in Gram-positive bacteria is uncommon, there are increasing reports of daptomycin resistance in Staphylococcus aureus, Enterococcus faecium and Enterococcus faecalis...

PURPOSE: We report the case of a 59-year-old man with chronic hepatitis B and C infection presenting with acute kidney injury and enterococcus faecalis-infective endocarditis (IE). An elevated proteinase-3 (PR3)-ANCA and pauci-immune glomerulonephritis (GN) on renal biopsy were discovered, corresponding to ANCA-mediated GN. We conducted a literature review to assess the role of ANCA in IE and treatment implications. METHODS: On systematic review of the literature, we found five previous cases whereby IE caused by streptococcus and bartonella species were related to ANCA vasculitis-associated GN...

We report the case of a 57-year-old man who presented with subacute bacterial endocarditis secondary to Streptococcus mutans complicated by biopsy-proven immune complex-mediated glomerulonephritis (ICGN). Despite initial treatment with antibiotics and a short course of corticosteroids, the kidney function further deteriorated, and plasmapheresis was introduced as third-line therapy to remove circulating immune complexes. Following 7 treatment sessions, the patient recovered kidney function. We discuss the potential merit of plasmapheresis for patients with subacute bacterial endocarditis who develop ICGN...

A 57-year-old man presented with abdominal pain, hematemesis, and melena. He reported taking high-dose ibuprofen for back pain and drinking several 24-ounce beers daily. Examination was remarkable for icteric sclera, poor dentition, tachycardia, and crescendo-decrescendo murmur at right upper sternal border, radiating to the carotids. Labs revealed leukocytosis, anemia, thrombocytopenia, and elevated liver function tests and INR. Endoscopy demonstrated antral ulcers, duodenitis, and esophagitis. Blood cultures were obtained and broad-spectrum antibiotics started; cultures later grew Streptococcus mitis, and antibiotic coverage was narrowed...

BACKGROUND: Cardiac device-related infective endocarditis is an uncommon but potentially fatal complication. Therefore, cardiac devices should be removed as soon as a device-related infection is suspected. CASE REPORT: A 56-year-old male with a history of arrhythmogenic right ventricular dysplasia with implantable cardioverter-defibrillators (ICDs) 7 years earlier and re-implantation of ICDs due to dysfunction 18 months ago presented with erosion of the ICD pocket with Pseudomonas bacteremia...

WHAT IS KNOWN AND OBJECTIVE: Enterococcus faecalis is the third most common causal agent of infective endocarditis. Currently, the treatment recommended is a combination of ampicillin (2 g/4 h) plus ceftriaxone (2 g/12 h), so patients must remain hospitalized for almost 6 weeks to receive the treatment. They are not generally included in outpatient parenteral antimicrobial therapy programs because 2 different electronic pumps are required to administer these 2 antibiotics. To enable the treatment of patients with E...

OBJECTIVE: To study the incidence and magnitude of bacteremia after dental extraction and supragingival scaling. SUBJECTS AND METHODS: Blood samples were taken before and 5 and 30 minutes after dental extraction and supragingival scaling from individuals at high (n=42) or negligible risk (n=53) for infective endocarditis. The former received prophylactic antibiotic therapy. Samples were subjected to aerobic and anaerobic culture and quantitative real-time polymerase chain reaction to determine the incidence of bacteremia and total bacterial levels...

Acute acalculous cholecystitis (AAC) is a necroinflammatory disease of the gallbladder with no gallstones present. ACC is known to be a serious, even potentially lethal complication observed mainly in patients with various severe underlying conditions including trauma, burn and sepsis. Infection of cardiac implantable electronic devices may lead to cardiac device-related infective endocarditis (CDRIE). The authors describe a case of a 55-year-old female with a history of advanced heart failure and implantation/reimplantation of biventricular pacemaker/defibrillator (CRT-D) for cardiac resynchronization therapy...
