Abstract:
Corticosteroids are anti-inflammatory medications used widely to treat allergic inflammation. Although the endocrine and gastrointestinal side effects of corticosteroids have been described, the occurrence of immediate hypersensitivity reactions and delayed contact dermatitis due to corticosteroids remains under-recognized. Hypersensitivity reactions can occur to a corticosteroid itself, or to the additives and vehicles in corticosteroid preparations. Skin testing and oral graded challenge can help confirm the suspected culprit agent in immediate hypersensitivity reactions and help identify an alternative tolerated corticosteroid. Patch testing can help identify the culprit agents in delayed hypersensitivity contact dermatitis. Cross-reactivity patterns have not been observed for immediate hypersensitivity reactions as they have been for delayed contact dermatitis. Sensitization in contact dermatitis exhibits cross-reactivity patterns based on corticosteroid structure. We review the current understanding regarding the clinical presentation, evaluation, and management of immediate and delayed hypersensitivity reactions to corticosteroids.

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
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...

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...
