743. Characteristics of Candidemia in a Coccidioidomycosis Endemic Region: The impact of Increased Azole Use in the Selection of Candida species

Sumario: | BACKGROUND: The incidence of invasive candidiasis secondary to non-albicans Candida species is on the rise. In Arizona, azoles are used for coccidioidomycosis treatment and prophylaxis in immunosuppressed population. Therefore, we intended to describe the characteristics and outcomes of non-albicans Candidemia in our area. METHODS: We conducted an IRB approved multicenter study evaluating patients from October 1, 2017 to January 1, 2020. Patient demographics, medical history, procedures, antifungal use, and laboratory data were collected. Episode per patient was included in the statistical analysis. RESULTS: In the study period, there were 145 patients with 151 candidemia episodes. For the episode-per-patient, median age was 51 (IQR 37-62), 45% were female, and 86% were Caucasian. 10% had a history of transplantation (40% HSCT and 60% SOT), and 22.5% had a history of cancer. 78% had another concomitant systemic infection. 4/80 (5%) and 12/102 (12%) had infective endocarditis. Only 5 (3.3%) had a history of coccidioidomycosis and 37 (24.5%) had exposure to azole therapy in the prior 3 months. 60% of the candidemia episodes were due to non-albicans Candida species, 27/37 (73%) had a prior history of azole therapy, 12/15 (80%) were transplant recipients, and 23/34 (80%) had cancer. The majority (71%) of patients initially received an echinocandin without a significant difference in mortality. Of all the admission episodes, there were 45/151 (29%) deaths and 7/151 (4.5%) were discharged to hospice. Not removing central catheters was associated with 60% of deaths (P=0.002). Infectious diseases consult was associated with lower mortality (OR 0.25, 95% CI 0.087-0 .70) and higher rates of catheter removal (OR 8, 95% 2.2-29.5). There was no difference in mortality between non-albicans versus albicans Candidemia (28.6% vs. 32%, P=0.7). CONCLUSION: Our study found higher rates of non-albicans Candidemia that are more eminent in transplant recipients and those with prior azole use, but this was not statistically significant. The removal of the central line and ID consultations was associated with a significant reduction in mortality. In Coccidioidomycosis endemic regions, the risk of non-albicans candida infections can be higher with the use of azoles; however, further studies are recommended.
