Frequency of the Paradoxical Effect Measured Using the EUCAST Procedure with Micafungin, Anidulafungin, and Caspofungin against Candida Species Isolates Causing Candidemia

摘要

We report data on the frequency of the paradoxical effect of echinocandins against Candida spp. (n = 602 incident isolates) using the EUCAST definitive document EDef 7.2 procedure. The paradoxical effect for one or more echinocandins was observed in 16% of the isolates. However, differences between species were found, and the paradoxical effect was more common in Candida tropicalis (P < 0.001). Caspofungin was the drug in which the paradoxical effect was most common, followed by anidulafungin and micafungin (P < 0.001).
