As the saying goes, “Autumn is here, rhinitis is here.” Whenever autumn arrives, it is also the season when people with allergic rhinitis suffer. Rhinitis is very much a common cold, which is a viral infection that causes inflammation of the nasal mucosa. What we now call allergic rhinitis needs to be checked for allergens, etc. to confirm the diagnosis. Generally, rhinitis caused by viral infection and bacterial infection after a cold belongs to acute rhinitis. There are also some recurrent acute rhinitis that turns into chronic rhinitis mainly manifested as nasal obstruction and poor ventilation. There is also dry rhinitis. Allergic rhinitis is classified into mild, moderate and severe, as well as intermittent and persistent. The percentage of asthma patients with allergic rhinitis is about 78%, compared to about 15% in the general population. The percentage of patients with allergic rhinitis with bronchial asthma is 38%, while in the general population it is only 2-5%. Therefore, the link between allergic rhinitis and asthma is very close. The respiratory tract is divided into the upper respiratory tract and the lower respiratory tract, for example, the part above the throat is called the upper respiratory tract and the part below the throat is called the lower respiratory tract. Allergic rhinitis occurs as a result of allergic inflammatory reactions in the nasal cavity caused by allergens, and allergic asthma is also an inflammatory reaction caused by allergens. These allergens include dust mites, molds, pollen, pets, etc. Allergic rhinitis and allergic asthma are actually allergic reactions occurring in different areas. Therefore, the concept of “one airway, one disease” has been proposed, indicating that allergic rhinitis and bronchial asthma are the same inflammatory disease, emphasizing the holistic concept of respiratory inflammatory diseases. For the treatment of allergic rhinitis and asthma, the first thing to do is to identify the allergens and avoid contact with them, the common allergens are dust, mites, fungi, animal fur, feathers, etc. Then the treatment must be formal and systematic. Asthma has many triggering factors, among which allergic rhinitis is a very important issue. Typical asthma is easy to identify, but we should be alert to some atypical asthma, for example, some patients often have a cold, then followed by a cough, which the patient does not think he or she has asthma, which is called cough variant asthma from the respiratory point of view. Once the disease is present, a combination of systemic and local anti-allergy medications, including antihistamines (oral or intranasal), nasal or/and inhaled glucocorticoids, leukotriene receptor antagonists, etc., should be taken under the guidance of a physician. It is important to emphasize that nasal spray hormones and/or inhaled hormones should always be used under medical supervision. For fall allergic rhinitis, the application of nasal spray hormones about two weeks before the onset of the disease can be a good preventive measure. Allergic rhinitis patients’ allergies are genetically related, so it is difficult to cure allergic rhinitis completely. Desensitization therapy is a promising treatment method. For example, some patients have only one allergen, so they should be treated for one allergen, but some patients are allergic to multiple allergens, so they should find 1 or 2 major allergens for treatment. Desensitization in asthma is also called specific immunotherapy, and it appears from the World Health Organization study that desensitization is beneficial for asthma, but only if it is done with a standardized allergen vaccine.
