What can airway remodeling result in?

• A. Improved lung elasticity
• B. Progressive, irreversible loss of pulmonary function
• C. Increased sensitivity to allergens
• D. Reversible airway obstruction

Answer: (B)

Airway remodeling refers to the structural changes that occur in the airways due to chronic asthma or other inflammatory conditions. These changes may include thickening of the airway walls, increased smooth muscle mass, and altered extracellular matrix composition. Such remodeling can lead to a progressive and irreversible loss of pulmonary function over time. This means that the airways may become permanently narrowed or obstructed, making it more difficult for air to flow in and out of the lungs and potentially leading to long-term deterioration in lung health. In contrast, improved lung elasticity, increased sensitivity to allergens, and reversible airway obstruction do not accurately represent the consequences of airway remodeling. Lung elasticity typically diminishes, and sensitivity to allergens may increase as a result of inflammation rather than remodeling itself. Overall, understanding the long-term effects of airway remodeling is crucial for managing asthma effectively.
