Overview on the Infections Related to Rare Candida Species

Area of Science:

• Medical Mycology
• Infectious Diseases
• Antimicrobial Resistance

Background:

• Atypical Candida species infections are rising, driven by an increase in immunocompromised patients.
• While Candida albicans remains common, non-albicans Candida species (e.g., C. glabrata, C. parapsilosis, C. tropicalis) are increasingly reported.
• Uncommon yeasts like Candida lusitaniae, Candida intermedia, and Candida norvegensis also show a worrying rise in reported infections.

Purpose of the Study:

• To review recent (last decade) information on infections, diagnosis, treatment, and antifungal resistance of uncommon Candida species.
• To highlight the growing incidence and clinical significance of these emerging fungal pathogens.
• To assess the current landscape of antifungal susceptibility for these atypical yeasts.

Main Methods:

• Literature review focusing on publications from the last 10 years.
• Synthesis of data on incidence, clinical manifestations, and diagnostic approaches.
• Analysis of reported treatment outcomes and antifungal resistance patterns.

Main Results:

• A notable increase in research articles concerning the incidence of uncommon Candida species.
• Evidence of emerging antifungal resistance, particularly to azole antifungals, in several species.
• Challenges in therapeutic success due to resistance patterns.

Conclusions:

• Uncommon Candida species represent a growing threat, especially in vulnerable populations.
• Antifungal resistance, particularly to azoles, is a significant concern requiring further investigation and monitoring.
• Effective diagnosis and treatment strategies are crucial for managing these infections.
