Pollen respiratory allergy: Is it really seasonal?

Area of Science:

• Allergy and Immunology
• Environmental Health
• Pharmacology

Background:

• Allergic rhinitis (AR) is a widespread condition significantly impacting quality of life.
• Traditional seasonal and perennial classifications inadequately address the evolving nature of AR triggers.
• Environmental factors like climate change and air pollution are increasingly implicated in AR development and persistence.

Purpose of the Study:

• To review factors contributing to year-round allergic rhinitis symptoms.
• To emphasize the need for continuous treatment strategies for AR management.
• To discuss updated AR classification and therapeutic options.

Main Methods:

• Literature review of factors influencing allergic rhinitis.
• Analysis of the impact of climate change and air pollution on pollen seasons and allergenicity.
• Evaluation of current and emerging treatment modalities for AR.

Main Results:

• Climate change and air pollution extend pollen seasons and increase allergenicity, leading to year-round AR symptoms.
• Existing AR classifications are insufficient to capture the continuous nature of the condition.
• Second-generation antihistamines are preferred over first-generation due to reduced sedation and cognitive impairment.

Conclusions:

• Allergic rhinitis management requires a shift towards continuous treatment strategies.
• Environmental factors necessitate a re-evaluation of AR classification and treatment paradigms.
• Further research into long-term, continuous AR management is crucial.
