Causes of asthmatic bronchitis infection in children

Children are the apple of their parents' eyes and play the role of parents' happy pills in the family. If a child suffers from childhood asthmatic bronchitis, as a parent, do you want to know more about childhood asthmatic bronchitis, including the causes of infection? As a wheezing disease, childhood asthmatic bronchitis will bring certain life-threatening dangers to children to a certain extent if parents do not understand the cause of infection. If they do not understand, they will not be able to prevent it well!

Asthmatoid bronchitis is a clinical syndrome that refers to a group of acute bronchial infections in infants and young children with wheezing. The lung parenchyma is rarely involved. Some of these children may develop bronchial asthma.

1. Reasons:

1. Infectious factors: It can be caused by a variety of viral and bacterial infections. The more common ones include syncytial virus, parainfluenza virus, influenza virus, adenovirus, rhinovirus and Mycoplasma pneumoniae. In most cases, bacterial infection may occur concurrently with viral infection.

2. Anatomical characteristics The trachea and bronchi of infants and young children are relatively narrow, and the elastic fibers around them are well developed. Therefore, their mucosa is easily infected or other stimulated and swells and becomes congested, causing the trachea to be narrowed and the secretions to be thick and difficult to cough out, thus producing wheezing.

3. Allergic constitution factors. Many infants and young children suffer from viral infections, but only a small number of them show symptoms of asthmatic bronchitis. This suggests that the different pathophysiological changes and clinical manifestations caused by the same virus in different individuals are closely related to the body's endogenous factors. For example, in recent years, it has been found that children with asthmatic bronchitis caused by syncytial virus have specific IgE antibodies, and the histamine concentration in their nasopharyngeal secretions is significantly higher than that of children with the same infection but without asthma. Their relatives often have a history of allergic diseases such as allergic rhinitis, urticaria, and asthma. About 30% of the children have suffered from eczema, and their serum SIgE levels are often elevated.

Only when we know the cause can we better prevent and solve the problem, we can better prescribe the right medicine, and we can better take care of our baby in daily life. When we know the cause, we can actively take our baby for treatment. What is the purpose of knowing the cause? There are two main points: First, find the cause and avoid allergens. Second, strengthen your physical fitness and prevent medication.
