Japanese guidelines for allergic rhinitis 2020.

Area of Science:

• Immunology
• Otolaryngology
• Public Health

Background:

• Allergic rhinitis is a prevalent allergic condition, distinct from asthma and atopic dermatitis.
• Severe allergic rhinitis, including pollinosis, substantially diminishes patients' quality of life (QOL).
• Existing guidelines necessitate updates to integrate current evidence-based medicine (EBM).

Purpose of the Study:

• To present the revised "Practical Guideline for the Management of Allergic Rhinitis in Japan 2016."
• To incorporate the latest evidence and EBM for comprehensive allergic rhinitis management.
• To provide a step-by-step treatment strategy and address QOL and cost-benefit analyses.

Main Methods:

• Supplementation of the 2016 guideline with recent evidence and literature.
• Inclusion of diagnostic and treatment assessments for pediatric and pregnant populations.
• Integration of QOL concepts and cost-benefit analyses.

Main Results:

• The revised guideline offers broad clinical applications, including for sinusitis, childhood allergic rhinitis, oral allergy syndrome, anaphylaxis, and pregnant women.
• An evidence-based, step-by-step treatment approach is detailed.
• The guideline incorporates QOL and cost-benefit considerations.

Conclusions:

• The updated guideline serves as a crucial resource for managing allergic rhinitis in Japan.
• It aligns with international standards like Allergic Rhinitis and its Impact on Asthma (ARIA).
• A new Q&A section enhances its utility for clinicians and patients.
