Driver Xiao Wang cheerful personality, usually like to travel with friends to play in the mountains, and inevitably party chat, but with the weather turning cold, Xiao Wang feel annoying nose affect his pleasant mood, morning up itchy nose uncomfortable, continuous sneeze a non-stop, the most damaging when eating or talking to people, nasal snot like water involuntarily flow down, had to let him wipe a non-stop. For a month, Xiao Wang ate a lot of cold medicine, but the symptoms did not significantly improve. The incidence of allergic rhinitis, also known as allergic rhinitis, has increased significantly with the cooler weather in the fall. Nearly half of the patients attending the ENT clinic suffer from rhinitis, and many of them have runny nose, itchy nose, sneezing, sometimes accompanied by itchy eyes and itchy nasopharynx. Allergic rhinitis is a common disease with a prevalence of more than 10% in the general population, and is also a chronic disease that should not be ignored. Because the inflammation of the upper and lower respiratory tracts is interactive, the onset of allergic rhinitis is closely related to asthma, and this interrelationship is especially evident in pediatric patients, who are more likely than adults to develop asthma if their allergic rhinitis is not actively treated. Can Xiao Wang’s disease be diagnosed as allergic rhinitis? Allergic rhinitis is an immune inflammatory disease of the nasal mucosa with definite allergens. Clinically, vasomotor rhinitis or drug rhinitis, etc. also show symptoms of allergic rhinitis, while some abnormalities of the nasal cavity structure may also affect the inflammatory state of the nose. Allergen testing is an important tool to confirm the diagnosis of allergic rhinitis, and commonly used methods of allergen testing include skin prick testing and serum specific immunoglobulin testing. How is allergic rhinitis treated? The most common method is medication, which is also symptomatic treatment, mainly glucocorticoid nasal spray, antihistamines, and anti-leukotriene drugs, which are simple and effective to use, but should be applied under the guidance of a specialist to minimize side effects and improve efficacy. Patients with combined nasal structure abnormalities or nasal polyps can be treated by nasal endoscopic surgery, and intranasal injection of long-acting hormone therapy is not advocated. Laser, microwave and plasma treatments cannot cure allergic rhinitis. For moderate and severe allergic rhinitis, specific immunotherapy can be used to change the immune status of the body through specific desensitization therapy to achieve the root cause, but the duration of immunotherapy is long and requires continuous medication for 1~3 years according to the doctor’s plan. There are two existing methods of immunotherapy: sublingual administration of dust mite drops and subcutaneous injection of allergens. Sublingual administration is convenient, less painful and more easily accepted. Clinically, many patients mistake allergic rhinitis for cold treatment, and diagnose “rhinitis” by themselves according to the book, and even apply a lot of antibiotic infusion treatment, which wastes money and delays the treatment, which is not worth the loss. The onset of allergic rhinitis is closely related to the individual’s constitution and environment, so there is still a lot of work to be done to reduce contact with allergens and active (immune) treatment, and it is important to treat both the symptoms and the root cause.
