Abstract:
The aim of current study is to describe clinical similarities and differences between atopic and non-atopic asthma in children. In a cross-sectional study, 95 asthmatic children (75 allergics and 20 nonallergics) were included in the study. Demographic, clinical, and familial history were compared between two groups. There was no significant differences between variables like sex, age of onset (p=0.75), severity (p=0.70), and family history among the two groups (p=0.42). Patients with allergic asthma were significantly older than those with non- allergic asthma (11.28 ± 3.19 and 9.75 ± 2.35 years, respectively, p=0.02). The controversy lingers over the presence of a completely distinct phenotype of non-atopic asthma in children. Our study suggested that phenotypes of allergic and non-allergic asthma in children were not entirely distinct.

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.

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

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...
