Abstract
PURPOSE Candidemia is associated with high mortality especially in critically ill patients. Our aim was to identify predictors of mortality among critically ill patients with candidemia with a focus on early interventions that can improve prognosis. METHODS Multicenter retrospective study. SETTING This retrospective study was conducted in Intensive Care Units from three European university hospitals from 2015 to 2021. Adult patients with at least one positive blood culture for Candida spp. were included. Patients who did not require source control were excluded. Primary outcome was 14-day mortality. RESULTS A total of 409 episodes of candidemia were included. Most candidemias were catheter related (173; 41%), followed by unknown origin (170; 40%). Septic shock developed in 43% episodes. Overall, 14-day mortality rate was 29%. In Cox proportional hazards regression model, septic shock (P 0.001; HR 2.20, CI 1.38-3.50), SOFA score ≥ 10 points (P 0.008; HR 1.83, CI 1.18-2.86), and prior SARS-CoV-2 infection (P 0.003; HR 1.87, CI 1.23-2.85) were associated with 14-day mortality, while combined early appropriate antifungal treatment and source control (P < 0.001; HR 0.15, CI 0.08-0.28), and early source control without appropriate antifungal treatment (P < 0.001; HR 0.23, CI 0.12-0.47) were associated with better survival compared to those without neither early appropriate antifungal treatment nor source control. CONCLUSION Early source control was associated with better outcome among candidemic critically ill patients.

Govrins M, Lass-Flörl C. Candida parapsilosis complex in the clinical setting. Nat Rev Microbiol 2024; 22:46-59. [PMID: 37674021 DOI: 10.1038/s41579-023-00961-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/03/2023] [Indexed: 09/08/2023]
Abstract
Representatives of the Candida parapsilosis complex are important yeast species causing human infections, including candidaemia as one of the leading diseases. This complex comprises C. parapsilosis, Candida orthopsilosis and Candida metapsilosis, and causes a wide range of clinical presentations from colonization to superficial and disseminated infections with a high prevalence in preterm-born infants and the potential to cause outbreaks in hospital settings. Compared with other Candida species, the C. parapsilosis complex shows high minimal inhibitory concentrations for echinocandin drugs due to a naturally occurring FKS1 polymorphism. The emergence of clonal outbreaks of strains with resistance to commonly used antifungals, such as fluconazole, is causing concern. In this Review, we present the latest medical data covering epidemiology, diagnosis, resistance and current treatment approaches for the C. parapsilosis complex. We describe its main clinical manifestations in adults and children and highlight new treatment options. We compare the three sister species, examining key elements of microbiology and clinical characteristics, including the population at risk, disease manifestation and colonization status. Finally, we provide a comprehensive resource for clinicians and researchers focusing on Candida species infections and the C. parapsilosis complex, aiming to bridge the emerging translational knowledge and future therapeutic challenges associated with this human pathogen.

Abstract
Candida auris is an emerging pathogen considered to be critical in the World Health Organization fungal organisms list. The study aims to determine the mortality and hospital stays attributed to Candida auris (C. auris) compared to other Candida species in adult patients with candidemia. A retrospective cohort of adults with candidemia was examined from seven centres in Colombia between 2016 and 2021. The primary outcome was 30-day mortality, and the secondary outcome was the length of hospital stay among survivors. Adjustment of the confounding variables was performed using inverse probability weights of exposure propensity score (candidemia by C. auris), survival regression models (Weibull distribution), and a counting model (negative binomial distribution). A value of 244 (47.6%) of the 512 patients with candidemia died within the first 30 days. The crude mortality in C. auris was 38.1% vs. 51.1% in Candida non-auris (CNA). In the Weibull model, mortality in the C. auris group was lower (adjusted HR: aHR- 0.69, 95% CI: 0.53-0.90). Antifungal treatment also decreased mortality, with an aHR of 0.36 (95% CI 0.27-0.47), while the presence of septic shock on patient progression increased it, with an aHR of 1.73 (95% CI 1.41-2.13). Among the patients who survived, no differences in the length of hospital stay were observed between the C. auris and the CNA groups, with an incidence rate ratio of 0.92 (95% CI: 0.68-1.22). Mortality in patients with C. auris bloodstream infections appears lower when adjusted for numerous confounding variables regarding treatment and the presence of septic shock in patient progression. We identified no significant effect of C. auris on the length of hospital stay in surviving patients.

Abstract
Background Despite advances in diagnostic and therapeutic approaches, candidemia remains associated with high mortality rates. This study aimed at identifying predictors of mortality among patients with candidemia, with a focus on early interventions that can improve prognosis. Methods This was a single-center retrospective study including all adult patients with at least 1 positive blood culture for Candida species from 2014 to 2021. Results A total of 222 episodes of candidemia were included. Most candidemias were of unknown origin (36%) or vascular catheter related (29%). Septic shock developed in 29% episodes. Overall, 14-day mortality rate was 23%. In univariate analyses, septic shock was associated with higher 14-day mortality, whereas catheter-related candidemia and early (<72 hours) interventions, such as appropriate antifungal therapy, source control, and infectious diseases consultation, were associated with improved survival. In a Cox multivariate regression model, septic shock (odds ratio [OR], 3.62 [95% confidence interval {CI}, 2.05–6.38]) was associated with higher mortality. While the impact of early antifungal therapy did not reach statistical significance, early (<72 hours) infectious diseases consultation (OR, 0.46 [95% CI, .23–.91]) and early source control (OR, 0.15 [95% CI, .08–.31]) were associated with better survival. Subanalyses showed that the benefits of early source control, specifically catheter removal, were significant among patients with sepsis or septic shock, but not among those without sepsis. These associations remained significant after exclusion of patients who died prematurely or were in palliative care. Conclusions Early source control, in particular catheter removal, was a key determinant of outcome among candidemic patients with sepsis or septic shock.

Abstract
Opportunistic fungal infections increase morbidity and mortality in COVID-19 patients monitored in intensive care units (ICU). As patients' hospitalization days in the ICU and intubation period increase, opportunistic infections also increase, which prolongs hospital stay days and elevates costs. The study aimed to describe the profile of fungal infections and identify the risk factors associated with mortality in COVID-19 intensive care patients. The records of 627 patients hospitalized in ICU with the diagnosis of COVID-19 were investigated from electronic health records and hospitalization files. The demographic characteristics (age, gender), the number of ICU hospitalization days and mortality rates, APACHE II scores, accompanying diseases, antibiotic-steroid treatments taken during hospitalization, and microbiological results (blood, urine, tracheal aspirate samples) of the patients were recorded. Opportunistic fungal infection was detected in 32 patients (5.10%) of 627 patients monitored in ICU with a COVID-19 diagnosis. The average APACHE II score of the patients was 28 ± 6. While 25 of the patients (78.12%) died, seven (21.87%) were discharged from the ICU. Candida parapsilosis (43.7%) was the opportunistic fungal agent isolated from most blood samples taken from COVID-19 positive patients. The mortality rate of COVID-19 positive patients with candidemia was 80%. While two out of the three patients (66.6%) for whom fungi were grown from their tracheal aspirate died, one patient (33.3%) was transferred to the ward. Opportunistic fungal infections increase the mortality rate of COVID-19-positive patients. In addition to the risk factors that we cannot change, invasive procedures should be avoided, constant blood sugar regulation should be applied, and unnecessary antibiotics use should be avoided.
