The number of patients with allergic rhinitis is increasing year by year, which is related to atmospheric pollution. Its prevalence can reach 40% in developed countries and is increasingly threatening people’s health. Allergic rhinitis is a series of pathological manifestations that individuals with allergic constitution show to special allergic substances, mainly four major symptoms: continuous sneezing, nasal itching, large amount of clear water-like nasal discharge and nasal congestion. I personally believe that once allergic rhinitis is diagnosed, the history of the disease is usually 20 to 30 years, but it will change after middle age and gradually heal itself (in fact, it is also a kind of desensitization or adaptation and tolerance of nature!) . But it cannot be left untreated. The danger lies in the complications of bronchial asthma, nasal polyps, smell disorder, headache and dizziness, as well as the great distress of life and work caused by the four symptoms. I. Diagnosis: Anyone who has continuous sneezing (less than 2~3 times, more than 10 times), accompanied by a large amount of clear water-like nasal discharge (uncontrollable) for more than 2 weeks can basically be diagnosed, such as going to a specialist and finding pale and swollen turbinate mucosa can basically be diagnosed. Of course, those who have the conditions can do skin allergen spot test (must stop using anti-allergic drugs for more than 5 days), or serum specific serum IgE (SIgE, not affected by drugs), total IgE test, which is better for diagnosis. Second, how to prevent attacks: 1, no pets at home such as cats and dogs; 2, no flowers and plants at home; 3, no carpets, as little as possible with cloth sofas; 4, pay attention to indoor ventilation, often clean the air conditioning filter; 5, do not live in a shady and humid place; 6, intimate clothing, bedding should be exposed to the sun once a week; 7, personal clothes washing should be soaked in hot water before washing (if possible, you can buy a tumble dryer with a heating function). When washing personal clothes, soak them in hot water before washing (if possible, you can buy a drum washing machine with heating function); 8, often participate in some physical exercise, actively adapt to nature, and also use cold water to wash your face. Third, treatment: 1, anti-allergy treatment (is the most basic effective treatment, generally choose one can, the effect is not good, you can choose the second generation of anti-allergy drugs during the day, at night before bedtime with three generations): such as antihistamines: the first and second generation have drowsy side effects such as: the first generation: paracetamol, ketotifen, the second generation: cetirizine, stavastine, ibastine, etc., it is recommended to use three generations such as: loratadine, diclazuridine, diclazuridine, diclazuridine, diclazurium, diclazurium, diclazurium, diclazurium. 2, anti-metabolite drugs (less often used alone with the addition of concurrent cough): such as anti-leukotriene (cisplatin), etc., must be used continuously for more than 2 months for allergic cough, asthma adjuvant therapy effective, 3, local closed treatment (has been less used except for some special occasions, interviews, etc.): sclerosing agents, steroid hormones, can only get better about One month long-term use of side effects, easy to cause skeletal osteoporosis, children are prohibited, 4, physical therapy: laser, microwave, plasma therapy, can only improve the symptoms for about 2 months. The cost is large, more painful and must be difficult 1-2 weeks of reaction period, in exchange for a relatively good 2 months, not quite worth, now only private hospitals are still strongly advocated, exaggerated efficacy. 5, local immunotherapy (also recommended by the World Health Organization, with anti-allergic drug therapy is set as the first line of combined medication methods): nasal spray with: endosulfan (the safest use of children), co-sulfan, Renocort, Burke sodium (all without significant side effects, no drowsiness). All the above treatments can only temporarily improve the symptoms. Since most allergic rhinitis is seasonal, as long as the medication is used continuously for one month when it flares up again, it is usually possible to get through the flare-up period. A good maintenance amount needs to be figured out by the patient. Only one medication such as (a third generation anti-allergy drug or steroidal glucocorticoid nasal spray once daily) is the ideal treatment. Specific immunotherapy (commonly known as desensitization therapy): steps: 1. first check the allergen: there are skin spot test, blood test two methods to choose one. 2. according to the allergen desensitization therapy, there are subcutaneous injection, and oral containing two methods, subcutaneous injection because of its longer history, can treat more kinds of allergens, but the disadvantage is to insist on the hospital injection and longer time (a year, start every 2 or 3 days), patients often can not adhere to. Patients are often unable to adhere to them. However, the disadvantage is that only dust (the most common allergen) can be treated and there are fewer varieties of allergens. The misconceptions and experiences of Changdi’s desensitization treatment (also the experience of all desensitization treatment): 1. The result of desensitization treatment and the root cause of allergic rhinitis are two different things. Not desensitization treatment will definitely cure. 2. But after 2 years of desensitization treatment, many patients can basically get off the medication, and almost every patient has improved clinical symptoms, and most of those who have improved significantly. 3. Pediatric patients have better results than adults, and the results of allergen testing: mite single high reaction (++++, ++++) are more obvious. Combined with asthma children should be more recommended. Surgical treatment: Many existing hospitals use nasal septum correction + inferior turbinate surgery for treatment, the effect is also very satisfactory, but can not cure the disease, about 50% reduction in symptoms, especially the improvement of nasal congestion, sneezing is particularly obvious, also may wish to try.
