Rhinitis and asthma share common inflammatory pathways and cells. While nasal inflammation mirrors bronchial inflammation, asthma exhibits distinct airway remodeling not seen in rhinitis.
Area of Science:
- Immunology
- Pulmonology
- Allergology
Context:
- Epidemiological data reveal a strong association between rhinitis and asthma.
- Four out of five asthmatics have rhinitis; one out of four rhinitic individuals develop asthma.
- Shared inflammatory cells and molecular mechanisms underpin both conditions' pathophysiology.
Purpose:
- To explore the link between rhinitis and asthma.
- To compare the inflammatory and remodeling features of rhinitis and asthma.
- To understand the basis for ARIA guidelines.
Summary:
- Cellular and molecular biology confirm shared inflammatory pathways in rhinitis and asthma.
- Histological analysis indicates similar nasal and bronchial inflammation but distinct airway remodeling in asthma.
- Differences in embryologic origin may explain the lack of remodeling in rhinitis.
Impact:
- Understanding the shared pathophysiology supports the ARIA guidelines.
- Clinical guidelines recommend screening asthmatics for rhinitis and vice versa.
- This highlights the importance of managing rhinitis in asthma patients and vice versa.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

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.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
