Allergic Fungal Rhinosinusitis Diagnosis, Management, Associated Conditions, Pathophysiology, and Future Directions:...

Area of Science:

• Otolaryngology
• Allergy and Immunology
• Pulmonology

Background:

• Allergic fungal rhinosinusitis (AFRS) is a distinct endotype of chronic rhinosinusitis with nasal polyps (CRSwNP).
• AFRS exhibits high recurrence rates and severe symptoms compared to other CRSwNP subtypes.
• Significant research gaps exist regarding AFRS, including outdated diagnostic criteria and unclear pathophysiology.

Purpose of the Study:

• To address the unmet needs in Allergic Fungal Rhinosinusitis (AFRS) research and patient care.
• To convene a multidisciplinary expert panel to discuss critical aspects of AFRS.
• To identify future research directions for AFRS diagnosis, management, and understanding.

Main Methods:

• A multidisciplinary meeting was held in December 2023 at the National Institute of Health.
• Experts included rhinologists, otolaryngologists, pulmonologists, allergists, immunologists, scientists, and infectious disease specialists.
• Discussions focused on patient management, diagnostic criteria, disease severity, pathophysiology, and related conditions.

Main Results:

• Identified outdated diagnostic criteria for AFRS.
• Highlighted the unclear mechanistic relationship of AFRS to other diseases.
• Emphasized the need for further study into AFRS pathophysiology and recurrence risk factors.

Conclusions:

• There is a critical need for dedicated research into Allergic Fungal Rhinosinusitis (AFRS).
• Future research should focus on refining diagnostic criteria and understanding disease mechanisms.
• Improved patient management strategies are required for this severe CRSwNP subtype.
