Allergic cough and wheeze, also known as cough variant asthma, is a specific type of bronchial asthma whose main typical clinical manifestation is a persistent, irritating, prolonged, dry, non-sputum cough. This disease is mainly due to the invasion of allergens, such as pollen, fumes, cold air, insect mites or eating allergic foods, such as high protein diet including milk, soy milk, eggs, etc. These allergic factors enter the body and cause a persistent chronic inflammation of the airways, which manifests as a high airway response and the symptoms described above. Clinically, symptomatic treatment can be chosen, mainly to stop coughing, calm asthma and resolve phlegm as the main treatment principle. Anti-allergic drugs as well as glucocorticoids and theophylline drugs can be chosen for rapid relief.
