As spring turns to autumn, it is again the season of suffering for allergic rhinitis patients, with symptoms such as itchy nose, sneezing, runny nose and nasal congestion, which seriously degrade the quality of life. Allergic rhinitis may also trigger complications such as asthma, sinusitis, conjunctivitis, and even be associated with other respiratory diseases such as chronic obstructive pulmonary disease, gastroesophageal reflux, and sleep apnea syndrome, so proper diagnosis and treatment is especially crucial. Many people mistakenly believe that people with low immunity are prone to allergic rhinitis, but in fact, the opposite is true: young and middle-aged people with high immunity are more prone to the disease. Allergic rhinitis is a manifestation of an immune imbalance, not a decline in immunity. In layman’s terms, it means that these people have too much autoimmunity, and they will overreact to allergens that people don’t react to, such as mites, pollen, mold, etc. They instinctively want to remove these allergens, and in the process of removing them their bodies can’t take it, and then they have allergic symptoms such as itchy nose, sneezing, nasal congestion, asthma, and itchy skin. Some studies have shown that the percentage of people with allergic diseases who develop malignant tumors is lower than that of the general population. For the treatment of allergic rhinitis, there are four main methods prevailing internationally as follows. One, patient education is to let patients understand allergic rhinitis and know how to standardize the diagnosis and treatment, which is the first key to control the disease, many hospitals are now vigorously carrying out patient education, which can effectively improve the quality of life of patients. Second, avoid allergens If it is a food allergy, it is generally easier to identify, the allergy symptoms are more obvious, and the symptoms appear urgent and heavy, and may even be life-threatening. For example, people with peanut allergy may experience anaphylactic shock or even death once they eat peanuts, so they should avoid eating such foods in the future. If you are allergic to airways, such as allergic to pollen, then every year in spring and autumn when pollen is more abundant, you can get out of this environment if you have conditions, such as moving from the north to live in the south, and the allergic symptoms will naturally disappear; if you cannot get out of the living environment completely, you can take such means as wearing a mask when you go out, going to the suburbs as little as possible, closing doors and windows, and cleaning your nasal cavity in time to minimize the exposure to allergens. Mites are also a common allergen, and it is difficult to avoid them completely, no matter they “escape” to the south or the north, they can only be reduced by using anti-mite mattresses, air filters, mite insecticides, washing bedding with warm water, regular exposure to the sun, freezing plush toys, thoroughly cleaning carpets, reducing dust, etc. Third, medication Since it is impossible to completely avoid allergens, some medication is also needed. Common drugs are antihistamines, nasal hormones, leukotriene receptor antagonists, etc., which are more effective and quicker to work, but can only control the symptoms, which will reappear once the drug is stopped, so it is not an effective way to change the course of the disease. Immunotherapy, also known as “desensitization therapy”, is one of the most important means of treating allergic rhinitis. It can correct the immune imbalance and help restore balance to the already imbalanced immune system. In 1998, the World Health Organization (WHO) proposed indications for immunotherapy, i.e., for patients who have failed or are intolerant to medication and have had poor results. 2001 saw a further step forward with the Allergic Rhinitis Guidelines (ARIA Guidelines), a very authoritative international document on the relationship between allergic rhinitis and asthma. In 2006, the concept of immunotherapy changed again and the medical community began to consider immunotherapy as an allopathic treatment that modifies the course of the disease and should be used as early as possible to avoid further irreversible lesions. For example, patients have already developed asthma, but due to irregular and untimely treatment, irreversible changes in certain organs have occurred, and then it is too late to choose immunotherapy. Immunotherapy can control allergy symptoms, patients do not need to use drugs for treatment anymore, and the quality of life can be greatly improved; it can also prevent the occurrence of new allergen allergy; it can prevent allergic rhinitis from developing into asthma. Therefore, immunotherapy has become an increasingly important means of treating allergic rhinitis. It should be reminded that immunotherapy also has certain limitations; patients with particularly severe asthma, people with systemic diseases, elderly people over 70 years old, and children too young for this method are not applicable.
