What Is Airway Inflammation?

The nature of airway inflammation and airway infection in asthma patients are completely different. The airway inflammation of asthma is allergic inflammation, while the inflammation of respiratory tract infection is bacterial inflammation. Due to different properties, the treatment method is completely different.

All patients with asthma have varying degrees of airway allergic inflammation, which is a key factor causing various clinical symptoms of asthma. The nature of airway inflammation in asthma patients is inconclusive at present, so it has long been generally referred to as non-specific inflammation. In recent years, most studies support asthma airway inflammation is Allergic inflammation, and some studies even think that all types of asthma are related to IgE. Therefore, many medical scientists support airway inflammation in all asthma patients. May be allergic, this view has been accepted by more and more scholars.

Clinical manifestations of airway inflammation

Cough variant asthma and typical asthma both have airway allergic inflammation and airway hyperresponsiveness. The causes and mechanisms are very similar, but the severity is different or the stages of disease progression are different. The quality and quantity of environmental allergic and non-allergic stimuli that induce airway inflammation are not consistent. In addition, there are large individual differences in the genetic quality of the body, which results in different organisms stimulating different environments. The result is not exactly the same. Due to the different degrees of pathological changes in different organisms, different clinical organisms or the same organism will produce different clinical manifestations at different times and occasions.

If the patient has significant airway inflammation that can stimulate bronchial smooth muscle spasm, it appears as wheezing; when the airway inflammation of asthma is relatively mild or superficial, it does not cause bronchial smooth muscle spasm or mild bronchospasm. Swelling is the main clinical manifestation of chest tightness. If only the surface of the airway mucosa is stimulated, it can only be clinically expressed as irritating dry cough. So slight airway inflammation may be cough variant asthma. ^[1]
