Abstract:
Polymicrobial endocarditis is more frequent in intravenous drug user (IVDU). Combined therapy--medical and surgical--represents the standard of care, but long-term suppressive therapy duration in fungal endocarditis is still debated. The polymicrobial endocarditis is rare: 1-3%. It is being observed with increasing frequency among drug users; a predominance of tricuspid valve involvement exists. We report a case of dual etiology infective endocarditis (IE) - Candida tropicalis and Staphylococcus aureus - in a IVDU; the treatment was combined, medical and surgical, and was followed by a suppressive antifungal therapy. We review the other published Candida tropicalis endocarditis cases and discuss their optimal management.
Insights
Polymicrobial endocarditis, often seen in intravenous drug users (IVDU), requires combined medical and surgical treatment. Long-term antifungal therapy duration for fungal endocarditis remains a key area for further research and clinical guidance.
Area of Science:
- Infectious Diseases
- Cardiology
- Mycology
Background:
- Polymicrobial endocarditis is a rare condition, affecting 1-3% of patients.
- Intravenous drug use (IVDU) is an increasing risk factor, often involving the tricuspid valve.
Observation:
- A case of dual etiology infective endocarditis (IE) involving Candida tropicalis and Staphylococcus aureus in an IVDU is presented.
- The patient received combined medical and surgical treatment.
Findings:
- Successful treatment involved a combination of medical and surgical interventions.
- The case was followed by suppressive antifungal therapy.
Implications:
- This case highlights the importance of combined therapy for polymicrobial endocarditis in IVDUs.
- Further discussion on optimal management and long-term antifungal therapy duration for Candida tropicalis endocarditis is warranted.
