Candida Endocarditis: A Review of Twelve Episodes in Eleven Patients

Candida spp. are a rare but important cause of infective endocarditis. The study aim was to describe pertinent clinical data on consecutive patients with Candida endocarditis treated at a tertiary referral center between 1984 and 2013.

A retrospective search of the authors' endocarditis database was performed and the medical records of patients with confirmed Candida endocarditis were reviewed. Important data relating to demographics, medical history and clinical data, as well as information on outcome and treatment, were extracted.

Between 1984 and 2013, a total of 12 episodes of Candida endocarditis in 11 patients (age range: 18 to 85 years) were treated at the authors' department (1.6% of all endocarditis episodes). Prosthetic valve endocarditis (PVE) was present in six patients. In 72% of cases the infection was healthcare-acquired. Endocarditis was shown to occur from 30 days to more than 600 days after cardiovascular surgery. Six patients were surgically treated. All removed valves were microbiologically positive, despite previous antifungal treatment. One patient with two episodes of Candida parapsilosis PVE was successfully treated conservatively, as was one patient with polymicrobial liver abscess, fungal spondylodiscitis and vegetation on the aortic valve. The total mortality rate was 45%.

Candida endocarditis has a high mortality, and because of its rare occurrence it is difficult to define the most appropriate treatment. There may be a considerable time lag between cardiovascular surgery and the advent of endocarditis.
