Can HIV cause endocarditis?

Endocarditis. The prevalence of infective endocarditis in HIV-infected patients is similar to that in patients of other risk groups, such as intravenous drug users. Estimates of endocarditis prevalence vary from 6.3% to 34% of HIV-infected patients who use intravenous drugs independently of HAART regimens.

Which of the following is the most accurate technique for evaluating infective endocarditis?

Serologic tests are often the most practical means for diagnosing valvular infection with fastidious organisms (eg, C burnetii and Chlamydia, Brucella, and Legionella species).

What is acute retroviral?

What are the immunologic phenomena and biologic evidence of infective endocarditis?

Immunologic phenomena: glomerulonephritis, Osler nodes, Roth spots, rheumatoid factor Microbiologic evidence: positive blood culture that does not meet major criteria, serologic evidence of active infection with organism consistent with infectious endocarditis Predisposing heart condition or history of injection drug use
