Increasing understanding of the pathophysiology of asthma at the histological level over the last two decades has emphasized airway inflammation as the primary player, over and above smooth muscle contraction, and airway hyperresponsiveness. An interplay of mast cells, T lymphocytes, and epithelial cells result in a circulatory surge of inflammatory cells and cytokines. Histamines, leukotrienes, and platelet-activating factors are found in increased concentrations locally and systemically. Lymphocytic and eosinophilic submucosal infiltrates in tracheal and bronchial biopsy specimens is reportedly associated with poorer outcomes in adult patients with asthma. [7]

Physiologically, acute asthma is divided into two phases. An early bronchospastic phase is observed within minutes after exposure to the allergen with mast cell degranulation and release of inflammatory mediators like histamine, prostaglandin D2, and leukotriene C4. A later inflammatory phase causing airway swelling and edema due to eosinophils released eosinophilic cationic proteins (ECP) and major basic protein (MBP).
