Abstract:
Anti-IgE therapy, using recombinant humanized anti-IgE antibodies, is clinically effective in patients with eosinophil-related disorders such as allergic asthma, allergic rhinitis, and chronic urticaria. Chronic eosinophilic pneumonia tends to respond promptly to systemic corticosteroid therapy, however; relapses are common following corticosteroid tapering. We treated two patients (17- and 19-yr-old males) of chronic eosinophilic pneumonia whose symptoms were cough and dyspnea on exertion. The symptoms were recurrent while tapering off corticosteroid. They were treated with anti-IgE antibody without recurrence for 2 yr and 15 months. Here, we first describe clinical experience of the 2 cases of chronic eosinophilic pneumonia.

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...

ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

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.
