Candida urinary tract infections--epidemiology

Area of Science:

• Medical Mycology
• Infectious Diseases
• Critical Care Medicine

Background:

• Candiduria is infrequent in healthy individuals but prevalent in hospitalized patients, particularly in intensive care units (ICUs).
• Predisposing factors in ICUs include diabetes mellitus, urinary catheter use, and prior antimicrobial exposure.
• Community-acquired candiduria is significantly less common.

Purpose of the Study:

• To differentiate between candiduria as colonization versus infection in critical care settings.
• To assess the clinical significance of candiduria in adult ICU patients and critically ill newborns.
• To determine the association between candiduria and mortality in ICU patients.

Main Methods:

• Review of clinical data and urine cultures from hospitalized patients, focusing on ICU populations.
• Analysis of predisposing factors, treatment outcomes, and mortality rates associated with candiduria.
• Distinguishing between asymptomatic colonization and invasive Candida urinary tract infection (UTI) or disseminated candidiasis.

Main Results:

• In most adult ICU patients, candiduria represents asymptomatic colonization, not requiring antifungal treatment.
• In critically ill newborns, candiduria frequently indicates disseminated candidiasis and can cause urinary tract obstruction.
• While candiduria is linked to increased mortality in ICU patients, it is seldom the direct cause of a Candida UTI.

Conclusions:

• Candiduria in adult ICU patients is predominantly colonization and rarely necessitates antifungal therapy.
• In critically ill neonates, candiduria warrants prompt investigation for disseminated candidiasis and potential urinary tract obstruction.
• Candiduria serves as a mortality marker in ICUs but is infrequently the attributable cause of infection.
