Κey Role of Early Source Control in Candidemic Patients With Sepsis or Septic Shock.

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 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.
