Epidemiology and risk factors for invasive candidiasis

Area of Science:

• Medical Mycology
• Infectious Diseases
• Epidemiology

Background:

• Immunosuppressive patient populations are growing, increasing susceptibility to opportunistic infections.
• Candidiasis remains a frequent fungal infection in these at-risk individuals.
• Recent advancements in antifungal therapies and treatment strategies have influenced infection patterns.

Purpose of the Study:

• To review the current epidemiology of invasive candidiasis.
• To identify key risk factors associated with invasive candidiasis.
• To analyze the changing species distribution of Candida in invasive infections.

Main Methods:

• Literature review focusing on invasive candidiasis.
• Analysis of epidemiological data and trends over the past two decades.
• Examination of studies on antifungal prophylaxis, secondary prophylaxis, and preemptive therapy.

Main Results:

• A significant increase in non-albicans Candida species causing invasive infections.
• A notable decrease in the incidence of Candida albicans, especially in immunosuppressed patients.
• Changes in Candida species distribution are linked to new therapeutic strategies.

Conclusions:

• The epidemiology of invasive candidiasis is evolving, with a rise in non-albicans Candida.
• Understanding these shifts is crucial for effective antifungal treatment and prevention strategies.
• Continued surveillance of Candida species distribution is necessary for public health.
