Invasive Candidiasis in the Intensive Care Unit: Where Are We Now?

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Mycology

Background:

• Invasive fungal infections, primarily candidiasis, are common in intensive care units (ICUs).
• While *Candida albicans* is historically dominant, non-*albicans Candida* species are increasingly implicated.
• Rising antifungal resistance in these species poses a significant clinical challenge.

Purpose of the Study:

• To review current epidemiologic trends of invasive candidiasis in the ICU.
• To discuss the diagnostic challenges associated with invasive candidiasis.
• To outline contemporary management strategies for invasive candidiasis in critically ill patients.

Main Methods:

• Review of current literature on invasive candidiasis in ICU settings.
• Analysis of epidemiologic trends, focusing on *Candida* species distribution.
• Evaluation of diagnostic approaches and antifungal treatment guidelines.

Main Results:

• Increasing incidence of invasive infections caused by non-*albicans Candida* species (*C. glabrata*, *C. parapsilosis*).
• Growing antifungal resistance observed in *Candida* species, complicating treatment options.
• Non-specific clinical manifestations and diagnostic delays contribute to increased morbidity and mortality.

Conclusions:

• Invasive candidiasis diagnosis and management in ICUs remain challenging.
• Prompt recognition and appropriate antifungal therapy are crucial for improving outcomes.
• Critical care physicians must maintain a high index of suspicion for invasive candidiasis.
