Occupational rhinitis (OR) and occupational asthma (OA) affect airways due to workplace agents. Research is exploring new pathways beyond T-helper cells to understand and improve diagnosis and treatment for these conditions.
Area of Science:
- Occupational medicine
- Immunology
- Pulmonology
Background:
- Occupational rhinitis (OR) and occupational asthma (OA) are distinct yet related conditions affecting the upper and lower airways, respectively.
- Both are characterized by airway inflammation, reduced caliber, and hyperresponsiveness, triggered by workplace agents.
- Current understanding is evolving beyond the traditional T-helper type 1/type 2 paradigm.
Purpose of the Study:
- To review current and emerging issues in occupational rhinitis and asthma.
- To highlight research relevant to both conditions, focusing on shared concepts and findings.
- To discuss advancements in objective assessment and future clinical applications.
Main Methods:
- Literature review of studies on occupational rhinitis and asthma.
- Focus on research discussing shared disease mechanisms and assessment methods.
- Analysis of evolving concepts in disease expression and clinical application.
Main Results:
- Occupational rhinitis and asthma share common features like airway inflammation and hyperresponsiveness.
- Emerging research explores alternative pathways including neural inflammation, epithelial barrier dysfunction, and autoimmunity.
- Objective assessment methods for OR and OA have improved for research and clinical use.
Conclusions:
- Understanding of occupational airway diseases is expanding to include novelpathways.
- Improved objective assessments are enhancing both research and clinical practice for OR and OA.
- Further developments in occupational rhinitis are anticipated to broaden its clinical application, mirroring progress in occupational asthma.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
