Summary
Allergic rhinitis (AR) patients in eastern China have a 14.23% asthma prevalence. Key asthma risk factors include allergies to Aspergillus fumigatus, D. pteronyssinus, and dog dander.
Area of Science:
- Pulmonology
- Allergology
- Epidemiology
Background:
- Asthma is a significant global health burden, often developing after allergic rhinitis (AR).
- Identifying concurrent asthma risk factors in AR patients is crucial for effective management.
Purpose of the Study:
- To investigate the risk factors associated with concurrent asthma in patients diagnosed with allergic rhinitis (AR) in eastern China.
Main Methods:
- A cross-sectional study involved 3739 AR patients in eastern China.
- Skin-prick tests (SPT) assessed sensitization to 16 common aeroallergens.
- Logistic regression analysis identified asthma risk factors in AR patients.
Main Results:
- The prevalence of asthma among AR patients was 14.23%.
- Dust mites (D. farinae, D. pteronyssinus) were the most common allergens.
- Allergies to Aspergillus fumigatus (aOR 2.42), D. pteronyssinus (aOR 2.06), and dog dander (aOR 1.92) were significant asthma risk factors.
- Risk factors varied across different age groups.
Conclusions:
- Distinct risk factors for asthma exist in AR patients.
- Understanding these risk factors can guide optimal asthma interventions.

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.
