Abstract:
The aim of the present study was to assess the relationship between serum eosinophil cationic protein levels and the severity of exercise-induced bronchoconstriction in asthmatic children. The 48 asthmatic children were divided into exercise-induced bronchoconstriction group and non-exercise-induced bronchoconstriction group. In the exercise-induced bronchoconstriction group, the post-exercise serum eosinophil cationic protein levels were significantly increased as compared with the pre-exercise serum eosinophil cationic protein levels. These results suggested that eosinophil cationic protein may serve as a possible contributor to the pathophysiology of exercise-induced bronchoconstriction in asthmatic children.

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

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.
