Background: Despite being considered a high-risk population for invasive fungal disease, specific features of candidemia among solid organ transplant (SOT) recipients remain poorly characterized. Methods: We compiled prospective data from two multicenter studies on candidemia performed over two consecutive periods in Spain: the CANDIPOP Study (2010-2011) and the CANDI-Bundle Study (2016-2018). Episodes diagnosed in adult SOT recipients in 10 participating centers were included. Risk factors for clinical failure (all-cause 7-day mortality and/or persistent candidemia for ≥72 hours) and 30-day mortality were investigated by univariate analysis. Results: We included 55 episodes of post-transplant candidemia (32 and 23 of which occurred during the first and second periods). Kidney (38.2%) and liver recipients (30.9%) were the most common populations. Candida albicans accounted for 27.3% of episodes. The proportion of C glabrata increased over time (18.8% vs 30.4% for the first and second periods). There were no differences in the rate of fluconazole non-susceptible isolates (50.0% vs 60.0%, respectively). Clinical failure and 30-day mortality occurred in 25.5% and 27.3% of episodes and were associated with the severity of candidemia (Pitt score and severe sepsis/septic shock). Kidney transplantation (unadjusted odds ratio [uOR]: 0.17; 95% confidence interval [CI]: 0.03-0.85; P-value =.020), early catheter removal (uOR: 0.15; 95% CI: 0.03-0.76; P-value =.013), and appropriate early antifungal therapy (uOR: 0.14; 95% CI: 0.02-0.89; P-value =.041) were protective for 30-day mortality. Conclusions: High rates of non-albicans species and fluconazole non-susceptibility must be taken into account to optimize therapeutic management and outcomes in SOT recipients with candidemia.

Abstract

Background: Despite being considered a high-risk population for invasive fungal disease, specific features of candidemia among solid organ transplant (SOT) recipients remain poorly characterized. Methods: We compiled prospective data from two multicenter studies on candidemia performed over two consecutive periods in Spain: the CANDIPOP Study (2010-2011) and the CANDI-Bundle Study (2016-2018). Episodes diagnosed in adult SOT recipients in 10 participating centers were included. Risk factors for clinical failure (all-cause 7-day mortality and/or persistent candidemia for ≥72 hours) and 30-day mortality were investigated by univariate analysis. Results: We included 55 episodes of post-transplant candidemia (32 and 23 of which occurred during the first and second periods). Kidney (38.2%) and liver recipients (30.9%) were the most common populations. Candida albicans accounted for 27.3% of episodes. The proportion of C glabrata increased over time (18.8% vs 30.4% for the first and second periods). There were no differences in the rate of fluconazole non-susceptible isolates (50.0% vs 60.0%, respectively). Clinical failure and 30-day mortality occurred in 25.5% and 27.3% of episodes and were associated with the severity of candidemia (Pitt score and severe sepsis/septic shock). Kidney transplantation (unadjusted odds ratio [uOR]: 0.17; 95% confidence interval [CI]: 0.03-0.85; P-value =.020), early catheter removal (uOR: 0.15; 95% CI: 0.03-0.76; P-value =.013), and appropriate early antifungal therapy (uOR: 0.14; 95% CI: 0.02-0.89; P-value =.041) were protective for 30-day mortality. Conclusions: High rates of non-albicans species and fluconazole non-susceptibility must be taken into account to optimize therapeutic management and outcomes in SOT recipients with candidemia.
