The new fungal opportunists are coming
1Duke University Medical Center, Durham, North Carolina 27710, USA.
Abstract:
Frequent and prolonged exposure of immunocompromised patients to a variety of environmental conditions has resulted in the recognition of infections with new fungal opportunists. Infections with fungi such as Fusarium species, Paecilomyces lilacinus, Acremonium species, Trichosporon beigelii, Blastoschizomyces capitatus, Malassezia furfur, Penicillium marneffei, Scedosporium prolificans, and other dematiaceous species have become significant problems in the treatment of immunocompromised hosts. This discussion addresses several issues of pathogenesis, epidemiology, diagnosis, and treatment with regard to these new opportunists, through a review of both general and specific concepts. The growing need for training in clinical mycology is also summarized.
Insights
Immunocompromised patients face new fungal infections from environmental exposures. This review covers pathogenesis, epidemiology, diagnosis, and treatment of these emerging fungal opportunists.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Immunocompromised Host Research
Background:
- Increased recognition of fungal infections in immunocompromised patients.
- Exposure to diverse environmental conditions contributes to opportunistic fungal infections.
- Emergence of novel fungal pathogens poses challenges in clinical settings.
Purpose of the Study:
- To review pathogenesis, epidemiology, diagnosis, and treatment of emerging fungal opportunists.
- To summarize general and specific concepts related to these infections.
- To highlight the need for enhanced clinical mycology training.
Main Methods:
- Literature review of general and specific concepts.
- Synthesis of information on pathogenesis and epidemiology.
- Discussion of diagnostic and therapeutic strategies.
Main Results:
- Identification of key fungal opportunists: Fusarium, Paecilomyces lilacinus, Acremonium, Trichosporon beigelii, Blastoschizomyces capitatus, Malassezia furfur, Penicillium marneffei, Scedosporium prolificans, and dematiaceous fungi.
- Significant challenges in treating these infections in immunocompromised hosts.
- Growing need for specialized training in clinical mycology.
Conclusions:
