Patterns and Predictors of Candida auris Candidemia with Multidrug-Resistant Bacterial Co-Infections: Results from the CANDI-MDR Study

Year: 2025

Type: article

Abstract: Introduction: Candida auris (now Candidozyma auris) and multidrug-resistant (MDR) bacterial infections pose significant therapeutic challenges due to high antimicrobial resistance, increased mortality, and persistence in healthcare settings. In Greece, their rising prevalence is raising concerns regarding co-infection, yet comprehensive data remain limited. This study aims to investigate the epidemiology, risk factors, and clinical outcomes of MDR bacterial co-infection in patients with C. auris candidemia. Methods: This single-center, retrospective observational cohort study was conducted at a Greek tertiary university hospital and included adult patients with C. auris bloodstream infections from January 2019 to June 2024. The data were analyzed using appropriate statistical methodologies. Results: Among 96 patients, those with C. auris candidemia and MDR bacterial co-infection exhibited a significantly higher mortality rate (87.23% vs. 61.22%, p = 0.007). The presence of a central venous catheter was the only factor significantly associated with MDR co-infection (p = 0.030). In univariate analysis, MDR co-infection, a higher Charlson Comorbidity Index, and mechanical ventilation correlated with increased mortality. Multivariate analysis identified MDR co-infection (OR = 3.19, p = 0.045) and mechanical ventilation (OR = 7.07, p = 0.002) as independent mortality predictors. Conclusions: These findings underscore the need for enhanced surveillance, precise identification, and stringent infection control measures to prevent C. auris and MDR bacterial outbreaks in healthcare settings.
