Examination, diagnosis and classification for Japanese allergic rhinitis: Japanese guideline

Area of Science:

• Immunology
• Otorhinolaryngology
• Public Health

Background:

• Allergic rhinitis (AR) prevalence is rising globally, posing a significant public health challenge, particularly in developed nations.
• AR is an IgE-mediated type I allergic reaction causing mucosal inflammation upon allergen exposure.
• Japanese cedar pollen-induced AR is a major health concern in Japan, with high patient consultation rates.

Purpose of the Study:

• To review the current standard diagnostic examinations for AR in Japan.
• To evaluate optimal AR classification systems applicable in the Japanese context.
• To provide support for daily clinical practice and facilitate patient selection for clinical trials.

Main Methods:

• Review of existing clinical guidelines for AR diagnosis and management.
• Analysis of current diagnostic practices employed by primary care physicians and otorhinolaryngologists in Japan.
• Evaluation of the usability and applicability of AR classification systems for non-specialists.

Main Results:

• Many AR patients in Japan do not receive adequate diagnostic examinations despite seeking medical care.
• Published AR clinical guidelines in Japan exist but have not been empirically tested.
• Existing guidelines may present challenges for non-specialist healthcare providers.

Conclusions:

• There is a need for improved and validated diagnostic approaches for AR in Japan.
• Optimizing AR classification is crucial for effective patient management and research.
• This review aims to enhance clinical decision-making and support clinical trial recruitment for AR.
