Candidemia infection remains a critical challenge in intensive care units (ICUs), with high morbidity and mortality rates despite advances in therapeutic practices. This multicenter prospective surveillance study assessed the epidemiology, clinical management, and mortality predictors of candidemia in critically ill patients across two periods (2010–2012 and 2017–2018) in 11 tertiary hospitals in Brazil. Among 314 ICU patients with candidemia, the overall mortality rate was 60.2%, with no significant reduction over time (58.8% vs. 62.6%, p = 0.721). Candida albicans was the predominant pathogen (43.6%), followed by C. tropicalis (20%) and C. glabrata (13.7%). The use of echinocandins increased significantly in the second period (21.1% to 41.7%, p < 0.001); however, 70% of patients still did not receive these agents as first-line therapy. Catheter removal due to candidemia was performed in only 52.1% of cases but was associated with improved 30-day survival (p < 0.001). Multivariate analysis identified cancer, inadequate treatment, and vasoactive drug use as independent predictors of mortality. Our findings underscore persistent gaps in adherence to guidelines, particularly regarding timely echinocandin initiation and catheter removal. Strengthening therapeutic strategies focused on these key interventions is essential to improving outcomes for ICU patients with candidemia.

Candida parapsilosis has emerged as a prominent cause of nosocomial candidemia, particularly among critically ill patients. The increasing prevalence of fluconazole-resistant C. parapsilosis (FR-Cp) poses major therapeutic challenges, especially in resource-limited settings. We conducted a retrospective study of 144 patients with C. parapsilosis candidemia admitted to two post-surgical ICUs at a Brazilian tertiary cardiothoracic hospital between 2016 and August 2024. Demographic, clinical, microbiological, and therapeutic data were analyzed. Predictors of 30-day mortality were identified through multivariate logistic regression. The incidence density of C. parapsilosis candidemia ranged from 2.93 to 8.31 per 1000 hospitalizations. Fluconazole resistance was identified in 81% of isolates. Overall 30-day mortality was 55%. Independent risk factors for mortality included cardiopathy (OR: 19.36, p = 0.006), higher SOFA scores (OR: 1.54, p = 0.003), parenteral nutrition (OR: 29.77, p = 0.013), and dialysis (OR: 6.59, p = 0.043), while longer treatment duration was protective (OR: 0.81, p < 0.001). Fluconazole resistance was not independently associated with increased mortality. In this cohort of critically ill patients, C. parapsilosis candidemia was associated with high mortality and a high prevalence of fluconazole resistance. Clinical outcomes were mainly driven by host-related and therapeutic factors rather than antifungal resistance alone.

Background: As infective endocarditis has particular characteristics compared to other infectious diseases, it is not clear if sepsis scores are reported with good accuracy in these patients. The aim of this study is to evaluate the accuracy of the qSOFA and SOFA scores to predict mortality in patients with infective endocarditis. Methods: Between January 2010 and June 2019, 867 patients with suspected left-sided endocarditis were evaluated; 517 were included with left-sided infective endocarditis defined as “possible” or “definite” endocarditis, according to the Modified Duke Criteria. ROC curves were constructed to assess the accuracy of qSOFA and SOFA sepsis scores for the prediction of in-hospital mortality. Results: The median age was 57 years, 65% were male, 435 (84%) had pre-existing heart valve disease, and the overall mortality was 28%. The most frequent etiologies were Streptococcus spp. (36%), Enterococcus spp. (10%), and Staphylococcus aureus (9%). The sepsis scores from the ROC curves used to predict in-hospital mortality were qSOFA 0.601 (CI95% 0.522–0.681) and SOFA score 0.679 (CI95% 0.602–0.756). A sub-group analysis in patients with and without pre-existing valve disease for SOFA ≥ 2 showed ROC curves of 0.627 (CI95% 0.563–0.690) and 0.775 (CI95% 0.594–0.956), respectively. Conclusions: qSOFA and SOFA scores were associated with increased in-hospital mortality in patients with infective endocarditis. However, as accuracy was relatively lower compared to other sites of bacterial infections, we believe that this score may have lower accuracy when predicting the prognosis of patients with IE, because, in this disease, the patient’s death may be more frequently linked to valvular and cardiac dysfunction, as well as embolic events, and less frequently directly associated with sepsis.
