Background
Candidemia is the fourth most common nosocomial bloodstream infection. Endocarditis from candidemia is a rare but possibly fatal complication. The efficacy of amphotericin and echinocandins for induction and azoles for suppression has been well studied. Source control of infection, including removal of foreign bodies, remains the cornerstone for the success of any antifungal therapy.
Case Presentation
We are describing a case of a 63-years old patient with multiple comorbidities who developed candidemia secondary to Candida albicans. The prospect of curing the fungemia was made difficult by prosthetic devices, including prosthetic heart valves, intracardiac defibrillator, and inferior vena filter, which could not be extracted due to poor cardiovascular status and higher postoperative mortality risk. Combination therapy with amphotericin and 5-Flucytosine (5FC) was used with the first recurrence. Suppression with fluconazole was contraindicated due to prolonged corrected QT (QTc) interval. Isavuconazole was employed for chronic lifelong suppression.
Conclusion
Retaining prosthetics in higher surgical risk patients presents us with unique clinical and pharmacological challenges regarding breakthrough infections, drug interaction, and side effects from prolonged suppressive therapies.
