There is no clear clinical concept of eosinophilic asthma. Bronchial asthma is a chronic airway inflammation with airway hyperresponsiveness involving a variety of inflammatory cells, and eosinophils are the end effector cells; sputum-induced eosinophil counts are elevated in the majority of asthmatics and correlate with asthma symptoms. Eosinophilic asthma is an inflammatory subtype of asthma, and more than half of asthma patients have this subtype. 1. Eosinophilic asthma typically presents with recurrent episodes of chest tightness, wheezing, expiratory dyspnea with rales, and sputum-induced eosinophil counts that are elevated >2.5%. 2. Eosinophilic asthma is usually treated with inhaled glucocorticoids as well as bronchodilators, such as salmeterol ticarcoson, budesonide formoterol, budesonide, and other drugs. In short, repeated episodes of chest tightness, wheezing, it is recommended that patients seek medical attention in a timely manner, in accordance with the doctor’s instructions to improve the relevant examination to clarify the cause of the cause of treatment.
