Non-Aspergillus Hyaline Molds: A Host-Based Perspective of Emerging Pathogenic Fungi Causing Sinopulmonary Diseases

Area of Science:

• Medical Mycology
• Infectious Diseases
• Immunocompromised Host Research

Background:

• The incidence of invasive sinopulmonary diseases caused by non-Aspergillus hyaline molds is increasing.
• This rise is attributed to a growing population of immunocompromised individuals and advancements in molecular diagnostics.
• Hyalohyphomycosis, particularly sinopulmonary infections, represents a significant challenge in clinical settings.

Purpose of the Study:

• To review opportunistic pathogens causing sinopulmonary hyalohyphomycosis.
• To elucidate the epidemiology and clinical features in various immunocompromised hosts.
• To summarize antifungal management strategies and adjunctive therapies.

Main Methods:

• A comprehensive literature review of opportunistic pathogens causing sinopulmonary disease.
• A host-based approach categorizing underlying conditions like neutropenia, hematologic malignancy, and transplantation.
• Analysis of pre-clinical and clinical data for antifungal and adjunctive treatments.

Main Results:

• Identified key pathogens including Fusarium spp., Scedosporium spp., Lomentospora prolificans, and others.
• Detailed the spectrum of sinopulmonary infections across diverse immunocompromised states.
• Summarized current antifungal armamentarium and emerging treatment considerations.

Conclusions:

• Understanding pathogen-specific epidemiology and host factors is crucial for managing sinopulmonary hyalohyphomycoses.
• Tailored antifungal therapy, potentially combined with surgery or immunomodulation, is essential for optimizing patient outcomes.
• Continued research into novel diagnostics and therapeutics is needed to combat these infections.
