[Acute Corynebacterium diphtheriae aortic endocarditis with negative blood cultures]
Summary
A challenging case of acute endocarditis caused by Corynebacterium diphtheriae in a teen was successfully treated. A cryopreserved allograft heart valve replacement resolved sepsis after mechanical valve failure.
Area of Science:
- Cardiology
- Infectious Diseases
- Cardiac Surgery
Background:
- Acute endocarditis with negative blood cultures presents diagnostic and therapeutic challenges.
- Effective management requires multidisciplinary collaboration among specialists.
Observation:
- A 15-year-old male presented with acute aortic endocarditis caused by Corynebacterium diphtheriae.
- Blood cultures were negative due to prior empiric antibiotic treatment.
- Initial surgical intervention with a mechanical prosthesis failed to resolve the sepsis.
Findings:
- Sepsis resolved following the implantation of a cryopreserved allograft.
- This highlights the effectiveness of specialized bacteriology centers.
Implications:
- Cryopreserved allografts offer advantages in managing active sepsis during endocarditis treatment.
- Successful treatment underscores the importance of specialized centers for complex infectious disease cases.
