Infective endocarditis occurs in males more often than in females. [1] The risk of death among those infected is about 25%. [6] Without treatment, it is almost universally fatal. [1] Improved diagnosis and treatment options have significantly enhanced the life expectancy of patients with infective endocarditis, particularly with congenital ...
The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus , Aggregatibacter (previously Actinobacillus ...
Endocarditis is an inflammation of the inner layer of the heart, the endocardium.It usually involves the heart valves.Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
Other strains of streptococci can cause subacute endocarditis as well. These include streptococcus intermedius, which can cause acute or subacute infection (about 15% of cases pertaining to infective endocarditis). [7] Enterococci from urinary tract infections and coagulase negative staphylococci can also be causative agents. [5]
[103] [127] GBS infections in adults include urinary tract infection, skin and soft-tissue infection (skin and skin structure infection) bacteremia without focus, osteomyelitis, meningitis and endocarditis. [3] GBS infection in adults can be serious, and mortality is higher among adults than among neonates. [103]
Current guidelines recommend daptomycin for VISA bloodstream infections and endocarditis. [4] Oxazolidinones such as linezolid became available in the 1990s and are comparable to vancomycin in effectiveness against MRSA. Linezolid resistance in S. aureus was reported in 2001, [101] but infection rates have been at consistently low levels.
Nonbacterial thrombotic endocarditis (NBTE) is a form of endocarditis in which small sterile vegetations are deposited on the valve leaflets. Formerly known as marantic endocarditis , which comes from the Greek marantikos , meaning "wasting away". [ 1 ]
Bacteria can also spread via the blood to other parts of the body (which is called hematogenous spread), causing infections away from the original site of infection, such as endocarditis or osteomyelitis. [citation needed] Treatment for bacteremia is with antibiotics, and prevention with antibiotic prophylaxis can be given in high risk ...
