Invasive candidemia is a major cause of increased mortality among ICU patients. Antifungal agents like liposomale amphotericin B and azoles could not accomplish the claim to be first choice in the treatment of invasive fungal infection (IFI) because of side effects and effectiveness. Especially, cardiothoracic surgery patients as a group of high-risk patients are in a focus for new strategies and agents. A new class of antimycotic agents, the echinocandins, with a low profile of side effects, low interactive potential and high effectiveness in the treatment of candidemia, is a powerful option in the treatment of IFI. We report our single-center experience with a modified clinical treatment approach based on clinical score of Leon and using echinocandins as first-line therapy for proven and suspected fungal infection.
Mean age was 67.4 years with 64% male patients. Most patients had combined CABG and valve procedure (n = 20), other groups were HTX and LTX (n = 4), assist therapy (n = 4), TAVI (n = 3) and other procedures. Mean predicted mortality using the logarithmic CASUS score at the onset of IFI was 59%. C. albicans was isolated in 73%, C. glabrata in 21%. Length of antifungal treatment using micafungin in 30 cases was 14 ± 5 days. Eradication of yeast was successful in 79% but mortality of all patients remains high at 36.8% but was lower than predicted in the CASUS score. Mortality was not yeast related.
Our described treatment approach shows encouraging results for the treatment of IFI especially in high-risk cardiothoracic patients.
