Cough is a common symptom of respiratory illness in children and is commonly caused by respiratory tract infections. However, in some children, the cough is always persistent and does not improve with the use of various antibiotics and cough medicines. Cough variant asthma is characterized by paroxysmal cough and wheezing, but cough variant asthma is mainly characterized by coughing without wheezing and lung examination without croup and rales. It is often triggered by respiratory infections, but when treated with antibiotics, the cough persists or recurs, and is often overlooked. Therefore, when a child has a persistent cough, he or she should be seen by a regular health care provider promptly and provide details of the child’s condition, including treatment with antibiotics. The following conditions may help in the diagnosis of cough variant asthma: 1. persistent or recurrent cough attacks for more than 1 month, often at night and/or early in the morning, aggravated by exercise, low sputum, no clinical signs of infection, or ineffective with long-term antibiotic therapy; 2. treatment with bronchodilators may relieve the cough (basic diagnostic condition); 3. personal history of allergies such as eczema, or family history of allergies, positive allergen test (secondary diagnostic condition); 4. 4. airways are hyperreactive and the bronchial excitation test is positive (auxiliary diagnostic condition); 5. chronic cough caused by other causes, among others. Cough variant asthma in children is a special type of asthma and in principle the treatment is based on the principles of asthma. A specific treatment plan is determined by an asthma specialist and long-term follow-up is performed.
