Purpose Of Review:
Interleukin 5 (IL-5) has been shown to play an instrumental role in eosinophilic inflammation in allergic diseases. The purpose of this review is to explore clinical trials of anti-IL-5 antibody therapy that have been conducted in patients with asthma, hypereosinophilic syndromes, eosinophilic esophagitis, atopic dermatitis, Churg-Strauss syndrome, and nasal polyposis.
Recent Findings:
Recent trials of anti-IL-5 in patients with severe asthma refractory to existing therapies and prominent sputum eosinophilia experienced significant reductions in asthma exacerbations. Studies in patients with hypereosinopihilic syndromes have shown that IL-5 antagonism allows significant reductions in systemic corticosteroid doses while maintaining or improving blood eosinophil counts and symptoms. In children and adults with eosinophilic esophagitis, anti-IL-5 treatment reduced eosinophil numbers in esophageal tissue; it is uncertain whether these findings are predictive of clinical improvement. Clinical studies of individuals with atopic dermatitis do not support efficacy of anti-IL-5 in either reducing allergen patch test intensity or symptoms of chronic dermatitis. In small trials in both Churg Strauss syndrome and nasal polyposis, anti-IL-5 shows promise but larger numbers of patients with these conditions will need to be studied.
Summary:
Anti-IL-5 is efficacious in treating patients with severe asthma and sputum eosinophilia and hypereosinophilic syndromes. Larger controlled trials with appropriate endpoints will be necessary to assess the role of anti-IL-5 in other eosinophilic disorders.

01:25Antiasthma 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...

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.
