Biologics in allergic rhinitis.

This paper aims to review biologics in allergic rhinitis (AR). Biologic agents of Omalizumab, Dupilumab, Mepolizumab, Reslizumab, and Benralizumab are reviewed in detail. The search is performed in "Pubmed," "Google," Google Scholar" and EBSCO Academic Search Ultimate (EKUAL) database of Kırıkkale University Library from 2021 to 2000, and randomized and/or placebo-controlled studies, review papers, meta-analysis, and reports are taken into consideration. The search was performed with the keywords of "allergic rhinitis," "biologics," "biologic agents," "Omalizumab," "Dupilumab," "Mepolizumab," "Reslizumab," "Benralizumab," "Anti IgE," "Anti-IL-4/IL-13", "Anti IL-5". Search is also performed in the "U.S. Food and Drug Administration" (FDA) and "European Medicines Agency" (EMA) web systems. Biological agents such as monoclonal antibodies (MAb) in treatment are called biological therapy or biotherapy. Omalizumab is a humanized Anti-IgE monoclonal antibody. Omalizumab treatment improved the Daily Nasal Rescue Medication Score (DNSSS) and decreased the use of antiallergic drugs in seasonal and perennial AR and rhino-conjunctivitis. Omalizumab is also used in specific immunotherapy patients with allergic rhinitis and reduced allergic reactions associated with allergen immunotherapy, such as anaphylaxis. Dupilumab is an Anti-IL-4/IL-13 biologic agent. Dupilumab treatment significantly improved sino-nasal Outcome Test (SNOT-22) total scores in perennial allergic rhinitis. Anti-IL-5 monoclonal antibodies of Mepolizumab, Reslizumab Benralizumab reduce the number of eosinophils in the blood and tissue, corticosteroid addiction and asthma attacks are reduced, and their use in the treatment of severe eosinophilic asthma has been approved. Biologics, especially Omalizumab, and Dupilumab, may be used more in allergic rhinitis.
