Abstract
Invasive candidiasis is known to be one of the most common healthcare-associated complications and is caused by several Candida species. First-line drugs, particularly echinocandins, are effective, but there are increasing reports of resistance to these molecules, though rarely related to C. albicans. Even though the rate of echinocandins resistance remains low (<3%), sporadic cases are emerging. Here, we present a case of bloodstream infection by a pan-echinocandin-resistant Candida albicans affecting a critically ill patient, who died in an intensive care unit following therapeutic failure and multiple organ dysfunction syndrome. This case highlights the need to suspect pan-echinocandin resistance in patients with prolonged echinocandin exposure, particularly in the presence of urinary tract colonization. Our study shows the importance of sequencing to predict therapeutic failure in patients treated with echinocandins and persistent candidemia.
