[Selected risk factors of fungal infections in human populations]

Area of Science:

• Infectious Diseases
• Medical Mycology
• Clinical Microbiology

Background:

• Invasive fungal infections (IFIs) have shown a significant increase over the past 20 years, contributing to high morbidity and mortality rates.
• The rise in IFIs is linked to advancements in invasive diagnostic and therapeutic technologies.
• Key risk factors include immunosuppression, neutropenia, broad-spectrum antibiotics, corticosteroids, chemotherapy, central venous catheters, and total parenteral nutrition, all common in hospitalized patients.

Purpose of the Study:

• To highlight the increasing burden of invasive fungal infections.
• To identify major risk factors associated with these infections in hospitalized patients.
• To underscore the diagnostic challenges in managing fungal infections.

Main Methods:

• This study is a review of current literature and clinical observations regarding invasive fungal infections.
• Analysis of risk factors commonly encountered in hospital settings.
• Evaluation of the current diagnostic landscape for fungal infections.

Main Results:

• Invasive fungal infections have dramatically increased over the past two decades.
• Hospitalized patients with fungemia face a higher mortality risk compared to those with non-fungal bloodstream infections.
• Despite the increasing incidence, the diagnosis of fungal infections remains challenging.

Conclusions:

• The rising incidence of invasive fungal infections poses a significant threat to patient health, necessitating improved diagnostic and therapeutic strategies.
• Identifying and mitigating risk factors in vulnerable patient populations is critical.
• Advancements in diagnostic methods are urgently needed to combat the challenges posed by fungal infections.
