Primary actinomycotic endocarditis: case report and review
1Department of Medicine, Long Island Jewish Medical Center, New Hyde Park, New York 11042.
Summary
Endocarditis caused by Actinomyces israelii with an unknown entry point is rare, predominantly affecting males. Early diagnosis and penicillin treatment offer a good prognosis for this actinomycosis infection.
Area of Science:
- Cardiology
- Infectious Diseases
- Microbiology
Background:
- Actinomycosis endocarditis is a rare clinical presentation.
- Identifying the portal of entry for Actinomyces species in endocarditis is often challenging.
Observation:
- This report details a case of primary Actinomyces israelii endocarditis with an unidentified source.
- A literature review identified seven similar cases since 1939, predominantly affecting males.
Findings:
- Clinical manifestations of Actinomyces endocarditis resemble those of other bacterial endocarditis.
- Penicillin is the recommended antimicrobial agent for treating Actinomyces endocarditis.
- Optimal treatment duration remains undetermined.
Implications:
- Early diagnosis and prompt antimicrobial therapy are crucial for favorable outcomes.
- This case highlights the importance of considering Actinomyces in the differential diagnosis of culture-negative endocarditis.
- Further research is needed to establish optimal treatment protocols for Actinomyces endocarditis.
