Background:
Fungal endocarditis is a rare form of infective endocarditis associated with a high risk of mortality. Candida parapsilosis is the most common nonalbicans species, with cases arising in the setting of intravenous drug use, prosthesis, prolonged hospitalization, or immunocompromised states.
Case Summary:
We report a 33-year-old man with a history of sickle cell disease and chronic nonhealing lower extremity wounds with persistent candidemia and Candida endocarditis of the tricuspid valve. The clinical course was complicated by septic pulmonary embolism, which was treated with suction thrombectomy.
Discussion:
This case documents the clinical course and adverse events of tricuspid valve Candida parapsilosis endocarditis in a patient with no previously identified risk factors or history significant for this location and subtype.
Take-Home Messages:
In patients with Candida endocarditis who are unresponsive to monotherapy, dual antifungal therapy should be considered. Because of the potential for significant sequelae from embolization, early surgical management should be considered if medical management is ineffective.
Insights
This case highlights Candida parapsilosis endocarditis in a patient with sickle cell disease. Early surgical intervention and dual antifungal therapy are crucial for managing this rare, high-mortality infection.
Area of Science:
- Cardiology
- Infectious Diseases
- Mycology
Background:
- Fungal endocarditis is a rare but severe condition, often fatal.
- Candida parapsilosis is a common non-albicans Candida species causing endocarditis.
- Risk factors include intravenous drug use, prosthetics, hospitalization, and immunosuppression.
Observation:
- A 33-year-old male with sickle cell disease and chronic leg wounds presented with persistent candidemia.
- Tricuspid valve endocarditis caused by Candida parapsilosis was diagnosed.
- The patient experienced a septic pulmonary embolism, treated with suction thrombectomy.
Findings:
- This case details the clinical course of tricuspid valve Candida parapsilosis endocarditis.
- The patient had no typical risk factors for this specific fungal endocarditis.
- Adverse events included septic pulmonary embolism.
Implications:
- Dual antifungal therapy may be necessary for refractory Candida endocarditis.
- Early surgical intervention is vital if medical management fails, especially to prevent embolic complications.
- This case underscores the importance of considering fungal endocarditis in at-risk populations, even without classic risk factors.
