Background:
Asthma is a multifactorial disease and its severity varies with the inflammatory grade. There are conflicting reports about the roles of trace elements in asthma. This study examined the effects of zinc (Zn), copper (Cu), and selenium (Se) concentrations in sera of patients with allergic asthma attending Ghaem Hospital, Mashhad, Iran.
Methods:
Forty-nine patients, aged 10 to 50 years, with asthma in moderate or severe stages, and 24 healthy controls, were enrolled in this study. After demographic data collection and clinical evaluations, the subjects' serum concentrations of Zn, Cu, and Se were measured via atomic absorbency.
Results:
Mean serum levels of Zn and Se in patients with allergic asthma were lower than in the healthy control group, but the Cu concentration in sera of patients with allergic asthma was slightly higher than healthy controls.
Conclusion:
Low levels of trace elements, specifically Zn, may have a role in the pathogenesis of allergic asthma; replacement of these elements may be an effective treatment.

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 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.
