Abstract

Asthma is a chronic disease found in all age groups. The patients experience chronic airway inflammation, and are hypersensitive to stimuli leading to exacerbating respiratory symptoms, including asthma exacerbations. Patients with severe asthma always take high-dose inhaled corticosteroids plus symptom-relieving drugs, and oral corticosteroids could be added to control asthmatic diseases. However, taking high doses of oral corticosteroids has been associated with higher rates of morbidity and mortality. It is found that type 2 inflammation has been implicated in the pathophysiology of asthma, and biomarkers have been determined so that the asthma endotype was known and response to therapy could be predicted. Currently, there are monoclonal antibodies, which are biological agents for treating severe asthma, including omalizumab, which acts on IgE, mepolizumab and reslizumab act on interleukin (IL)-5, benralizumab acts on IL-5 receptor, dupilumab acts on IL-4 receptor, and tezepelumab acts as an anti-thymic stromal lymphopoietin. There are also potential biological agents under investigation for the treatment of severe asthma. This article reviews the pathophysiology of severe asthma, including the disease's phenotype and endotype, as well as relevant biomarkers and recommendations for selecting biological agents suitable for patients with severe asthma.
