Treatment of cough variant asthma

Many patients with cough variant asthma want to know what the treatments for cough variant asthma are. In fact, if we want to understand the treatments for cough variant asthma, we must first understand what cough variant asthma is, what kind of physical harm this disease will bring to patients, and what is the cause of cough variant asthma.

The cause of cough variant asthma is very complex. It is generally believed that cough variant asthma is related to genetics, immune status, and mental and psychological state. Cough variant asthma is also related to endocrine and health status.

Cough asthma, also known as cough variant asthma, refers to a special type of asthma with chronic cough as the main or only clinical manifestation. When bronchial asthma first occurs, about 5% to 6% have persistent cough as the main symptom, which often occurs at night or early in the morning and is often an irritating cough. At this time, it is often misdiagnosed as bronchitis. The age of onset is higher than that of typical asthma, with about 13% of patients being older than 50 years old, and it is more common in middle-aged women. In children, coughing may be the only symptom of asthma, or even a precursor to the development of bronchial asthma. The number of patients in hospitals has also increased significantly.

1. Among adults with cough asthma, the age of onset is higher than that of typical asthma. About 13% of patients are over 50 years old, and middle-aged women are more common. In children, coughing may be the only symptom of asthma or even a precursor to developing bronchial asthma.

2. Most of them have a clear family history of allergies or a history of allergic diseases in other parts of the body, such as allergic rhinitis, eczema, etc.

3. Most attacks have a certain seasonality, mostly in spring and autumn.

4. The main clinical manifestations are long-term stubborn dry cough, which is often triggered by exercise, inhalation of cold air, or upper respiratory tract infection, and worsens at night or early morning. There is no wheezing during physical examination, and lung function damage is between that of normal people and typical asthma. Skin allergen tests may be positive.

5. The bronchial provocation test is positive. When a positive reaction occurs, an irritating cough similar to that during the onset of the disease may occur, indicating the presence of airway hyperresponsiveness; the reversibility test of airway obstruction is positive.

6. General cough suppressants and expectorants and antibiotics are ineffective, but antihistamines, β2-receptor agonists, theophyllines or corticosteroids can provide relief.

Because its essence is the same as typical asthma, it is a chronic nonspecific inflammation of the airways caused by allergens or other triggers, as well as the airway hyperresponsiveness and intractable cough formed on this basis. Therefore, the treatment principles are the same as those for typical asthma, mainly using bronchodilators, oral theophylline drugs and (or) β2 receptor stimulants. Some anti-allergic and mast cell stabilizing drugs such as nedocromil, cromoglycate, and ketotifen can also achieve good results. If these drugs are ineffective, consider using adrenal glucocorticoids, adding beclomethasone (beclomethasone dipropionate) aerosol or oral prednisone, and try nebulized inhalation of anticholine drugs.

In the above article, we introduced what cough variant asthma is. We know that cough variant asthma is also called cough asthma. There are many causes of cough variant asthma, so it brings trouble to our treatment of cough variant asthma. The above article introduces in detail the treatment methods of cough variant asthma.
