A comparison of skin test reactions in allergic rhinitis and patients with asthma/rhinitis
Abstract:
A comparison of skin test reactions in allergic rhinitis patients and cases of combined allergic rhinitis and asthma shows a significantly higher proportion of positive reactions to all allergens tested in the asthma/rhinitis patients. Both groups of patients exhibited as expected more positive reactions than a group of controls with house dust mite, and house dust eliciting the highest proportion of reactions. The asthma/rhinitis patients also showed a higher ratio of strong (grades III and IV) to weak (grades I and II) reactions than the allergic rhinitis group. This indicates a stronger allergic sensitivity state in the former group and may be of relevance in deciding the modalities of management.

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.
