摘要

Cancer patients are at risk for candidemia, and increas- ing Candida spp. resistance poses an emerging threat. We determined rates of antifungal drug resistance, identified factors associated with resistance, and investigated the correlation between resistance and all-cause mortality rates among cancer patients with ≥1 C. glabrata –positive blood culture at MD Anderson Cancer Center, Houston, Texas, USA, during March 2005–September 2013. Of 146 isolates, 30 (20.5%) were resistant to fluconazole, 15 (10.3%) to ca- spofungin, and 10 (6.8%) to multiple drugs (9 caspofungin- resistant isolates were also resistant to fluconazole, 1 to amphotericin B). Independently associated with fluconazole resistance were azole preexposure, hematologic malignan- cy, and mechanical ventilation. Independently associated with caspofungin resistance were echinocandin preexpo- sure, monocytopenia, and total parenteral nutrition. Fluco- nazole resistance was highly associated with caspofungin resistance, independent of prior azole or echinocandin use. Caspofungin resistance was associated with increased 28- day all-cause mortality rates. These findings highlight the need for good stewardship of antifungal drugs.
