Purpose Of Review:
Fungal endocarditis remains a rare disease occurring mostly in patients with predisposing host conditions. Regarding its poor prognosis because of severe complications, there is an urgent need for properly established treatment guidelines and prophylaxis for patients at risk. In this review we provide up-to-date information on treatment recommendations, and discuss recent case reports on fungal endocarditis and challenges in prophylaxis and treatment.
Recent Findings:
Over the last year, an increase in cases caused by non-albicans species of Candida and other fungi like Fusarium solani, Lodderomyces elongisporus and Exophiala dermatitidis was reported. They were treated individually in case-by-case approaches, lacking randomized controlled trials and, mostly, treatment recommendations.
Summary:
The scarcity of fungal endocarditis demands a high index of suspicion and knowledge of the group of at-risk patients. Diagnosis aggressively pursued by echocardiography and multiple blood cultures or surgical specimens has the potential to improve outcome. Candida endocarditis should be treated immediately, including surgical treatment in combination with liposomal amphotericin B or caspofungin with optional addition of flucytosine. Aspergillus endocarditis requires rapid surgery and voriconazole.
Insights
Fungal endocarditis is rare but serious, often affecting immunocompromised patients. Early diagnosis and prompt treatment with antifungals and surgery are crucial for improving outcomes in this challenging condition.
Area of Science:
- Infectious Diseases
- Cardiology
- Mycology
Background:
- Fungal endocarditis is a rare but severe infection of the heart valves.
- It predominantly affects patients with predisposing host conditions, leading to a poor prognosis.
- There is a critical need for established treatment guidelines and prophylaxis strategies.
Purpose of the Study:
- To provide up-to-date information on treatment recommendations for fungal endocarditis.
- To review recent case reports and discuss challenges in prophylaxis and treatment.
- To highlight the importance of early diagnosis and management.
Main Methods:
- Review of current literature and recent case reports on fungal endocarditis.
- Analysis of treatment approaches for various fungal species.
- Discussion of diagnostic modalities and prophylactic strategies.
Main Results:
- An increase in cases caused by non-albicans Candida species and other fungi (e.g., Fusarium solani, Exophiala dermatitidis) was reported.
- Treatment often involves individualized, case-by-case approaches due to a lack of randomized controlled trials.
- Lack of standardized treatment recommendations was noted.
Conclusions:
- Fungal endocarditis requires a high index of suspicion and awareness of at-risk patient groups.
- Aggressive diagnosis via echocardiography and cultures is vital for improving outcomes.
- Immediate treatment for Candida endocarditis involves surgery and antifungals (liposomal amphotericin B or caspofungin), while Aspergillus endocarditis necessitates rapid surgery and voriconazole.
