The difference between cough variant asthma and allergic asthma is mainly in the clinical manifestations, cough variant asthma with chronic cough as the main or only clinical manifestations. Allergic asthma, on the other hand, may be characterized by recurrent episodes of wheezing, shortness of breath, chest tightness or coughing.
Cough variant asthma (CVA) is a special type of asthma, which has chronic cough as the main or only clinical manifestation, and is an irritating dry cough with tickling of the throat, usually without obvious symptoms such as wheezing and shortness of breath. The cough is predominantly nocturnal. Symptoms such as chest tightness, dyspnea, and wheezing may occur with severe coughing.
Allergic asthma, also known as allergic asthma, can be characterized by recurrent episodes of wheezing, shortness of breath, chest tightness or cough.
There is no obvious difference between the causes and treatment of the two, and both can be treated with glucocorticosteroids (e.g., beclomethasone, prednisone, etc.), β2 agonists (e.g., salbutamol, terbutaline, etc.), leukotriene modifiers (e.g., montelukast), and anticholinergics (e.g., ipratropium bromide), etc., under the guidance of a physician.
Whether it is cough-variant asthma or allergic asthma, patients should seek prompt medical attention and treatment under the supervision of a physician. Medications should be used under the supervision of a physician.
