Infective endocarditis is associated with 18% in-hospital mortality. [24] However, adult patients with congenital heart disease can have relatively lower mortality down to 5% due to younger age, right-sided endocarditis and management by multidisciplinary teams. As many as 50% of people with infective endocarditis may experience embolic ...
[4] 10–25% of endocarditis patients will have Osler's nodes. [5] Other signs of endocarditis include Roth's spots and Janeway lesions. The latter, which also occur on the palms and soles, can be differentiated from Osler's nodes because they are non-tender. [3] Osler's nodes can also be seen in Systemic lupus erythematosus; Marantic endocarditis
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]
Another form of sterile endocarditis is termed Libman–Sacks endocarditis; this form occurs more often in patients with lupus erythematosus and is thought to be due to the deposition of immune complexes. [2] Like NBTE, Libman-Sacks endocarditis involves small vegetations, while infective endocarditis is composed of large vegetations. [2]
It’s also important to prevent endocarditis especially among high risk groups like for example those with prosthetic heart valves and a history of endocarditis. Before dental procedures, sometimes these people are recommended antibiotics, since remember that some of those microbes that cause endocarditis live in the mouth.
Janeway lesions are named after Edward Janeway (1841–1911), a prominent American physician, pathologist and contemporary of Sir William Osler, who initially described "peculiar skin lesions" in some people with endocarditis, in a paper published in 1899.
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 ...
Infective? Infective endocarditis related to Staphylococcus aureus: Generally large Yes Rheumatic fever related to Streptococcus pyogenes: Typically small Libman–Sacks endocarditis related to systemic lupus erythematosus: Small No (sterile) Nonbacterial thrombotic endocarditis (NBTE) Small No (sterile)
