Abstract

We determined the in vitro antifungal activity of liposomal amphotericin B (L-AmB) against 604 clinical yeast isolates. Amphotericin B deoxycholate (D-AmB) was tested in parallel against all the isolates. Susceptibility testing was performed according to the Clinical and Laboratory Standards Institute (CLSI) M27-A3 method. Overall, L-AmB was highly active against the isolates (mean MIC = 0.42 μg/ml; MIC90= 1μg/ml; 97.2% of MICs were ≤ 1μg/ml) and comparable to D-AmB (mean MIC = 0.48μg/ml; MIC90= 1μg/ml; 97.3% of MICs were ≤ 1μg/ml). The in vitro activity of D-AmB and L-AmB was correlated (R2 = 0.61; exp (Coef.) = 2.3; 95% IC= 2.19-2.44, p<0.001). Candida albicans (mean MICs of D-AmB and L-AmB, 0.39 μg/ml and 0.31 μg/ml, respectively) and Candida parapsilosis (mean MICs of D-AmB and L-AmB, 0.38 μg/ml and 0.35 μg/ml, respectively) were the species most susceptible to the agents tested, while Candida krusei (currently named Issatchenkia orientalis) (mean MICs of D-AmB and L-AmB, 1.27 μg/ml and 1.13 μg/ml, respectively) was the least susceptible. The excellent in vitro activity of L-AmB may have important implications for empirical treatment approaches and support its role in treatment of a wide range of invasive infections due to yeasts
