Abstract:
We present 2 cases of Aspergillus endocarditis occurring in lung transplant recipients, both of whom were treated with early surgical intervention and triazole anti-fungal agents. Neither had evidence of airway colonization/infection with Aspergillus post-transplant, suggesting hematogenous spread of fungi at the time of surgery as a possible mechanism of infection. One case was successfully treated and discharged from the hospital, but, despite initial recovery, death occurred 10 months later due to a recurrence of Aspergillus endocarditis. Aspergillus endocarditis should be considered a relapsing disease and survivors of the condition should receive ongoing anti-fungal therapy.
Insights
Aspergillus endocarditis is a serious complication in lung transplant patients. Early treatment with surgery and antifungals is crucial, but the disease can recur, requiring ongoing therapy.
Area of Science:
- Cardiology
- Infectious Diseases
- Transplant Surgery
Background:
- Aspergillus endocarditis is a rare but severe infection affecting heart valves.
- Lung transplant recipients are immunocompromised, increasing susceptibility to opportunistic infections like aspergillosis.
Observation:
- Two lung transplant recipients developed Aspergillus endocarditis without prior airway colonization.
- Hematogenous spread during surgery is a potential infection route.
Findings:
- Both patients received early surgical intervention and triazole antifungal therapy.
- One patient experienced a fatal recurrence 10 months post-discharge despite initial recovery.
Implications:
- Aspergillus endocarditis should be recognized as a potentially relapsing condition.
- Long-term antifungal therapy is recommended for survivors of Aspergillus endocarditis.
