  • Background: The optimal therapy for Candida infective endocarditis (IE) is unknown, and treatment guidelines are based largely on single site case series and case reports. The current guidelines have added echinocandins as a treatment option.  We sought to compare amphotericin B based therapy to echinocandin based therapy, using two large, prospective, international, multi-center cohorts of patients with definite IE.  

    Methods: We identified cases of definite Candida IE presenting between June 1, 2000 and September 30, 2011 from the International Collaboration on Endocarditis – Prospective Cohort Study (ICE-PCS) and the International Collaboration on Endocarditis Plus (ICE-Plus).  A supplemental case report form was sent to enrolling sites to gather detailed information on antifungal therapy.  We compared clinical characteristics and outcomes  based on antifungal regimen received. 

    Results: 72 cases of definite Candida IE were identified of which 33 had supplemental data on antifungal therapy available.  The most common infecting species were C. albicans (n=13) and C. parapsilosis (n=12).  Most patients received either an amphotericin B based regimen (33%) or an echinocandin based regimen (42%). Nearly half received combination antifungal therapy (45%) and surgical therapy was used in 13 patients (39%).  There was no difference in either 42 day or 1 year mortality between those receiving an amphotericin B based regimen vs. those receiving an echinocandin based regimen (36% vs. 36% and 64% vs. 69%, respectively, p=1).  

    Conclusion: This is one of the largest prospective series of Candida endocarditis patients to date.  In this cohort, there was no difference in mortality with echinocandin based therapy as compared to amphotericin B based therapy.  This study is limited by small sample size and observational data, however it lends support to the current recommendation of echinocandin based therapy as a viable treatment option for Candida endocarditis.
