Fungal Sensitization and Human Allergic Disease.

Area of Science:

• Mycology
• Immunology
• Clinical Medicine

Background:

• Fungal sensitizations are linked to hypersensitivity reactions, but evidence varies for different fungi.
• Lesser-studied fungi with commercial extracts require investigation for clinical utility.

Purpose of the Study:

• To systematically review the literature on lesser-studied fungi and their association with human hypersensitivity disorders.
• To identify the strength of evidence linking specific fungal sensitizations to clinical conditions.
• To determine the populations and diseases where these fungi may be clinically relevant.

Main Methods:

• Systematic literature review of scientific articles.
• Analysis of clinical data on fungal sensitization prevalence.
• Exclusion of fungi with extensive existing research.

Main Results:

• 54 articles provided clinical data for the studied fungi.
• Fungal sensitization prevalence varied among 12 fungi due to geographic, age, and medical factors.
• Seven fungal genera lacked studies linking them to human disease.
• Most commercial fungal extracts showed uncommon associations with hypersensitivity reactions.
• Specific extracts may benefit allergic fungal sinusitis, allergic bronchopulmonary mycosis, or severe asthma.

Conclusions:

• The clinical significance of many fungal sensitizations remains poorly defined.
• Targeted use of specific fungal extracts may be beneficial in select hypersensitivity disorders.
• Further research is needed to clarify the role of understudied fungi in allergic diseases.
