Antifungal Resistance: a Concerning Trend for the Present and Future

AbstractPurpose of ReviewThe global emergence of antifungal resistance amongCandida spp. andAspergillus spp. is a growing threat to public health, driven largely by the expanding use of antifungals in both the clinical and agricultural settings. As treatment options remain limited, understanding mechanisms and risk factors for antifungal resistance is essential to retaining their clinical utility.Recent FindingsInvasive candidiasis is increasingly caused by non-albicans Candida species with reduced susceptibility to first-line antifungals, making empiric treatment decisions difficult. Echinocandin resistance inC. glabrata is increasing at some high-risk centers, and multi-drug-resistant isolates are increasingly encountered. Of large concern is the rapid and global emergence ofC. auris, a species associated with a high propensity for developing multi-drug resistance and nosocomial transmission. Azole resistance is now becoming more common inAspergillus isolates as well, with breakthrough infections occurring in patients previously managed with azoles antifungals. The appearance of azole-resistantAspergillus isolates in azole-na ïve patients is also concerning, given it is now accepted that this may be due to the use of non-human azole compounds in pesticides.SummaryDue to the climbing use of antifungals in both the clinical and agricultural sectors, the frequency of encounters with antifungal-resistant isolates will undoubtedly rise in parallel. Antifungal stewardship will n...
