The prevalence of allergic rhinitis in children and adolescents can be as high as 40%, which can increase the prevalence of asthma by three times. It is closely related to sinusitis, respiratory infections and otitis media. Allergic rhinitis itself and its related diseases seriously harm the health, growth and development of children. Zhang Hanzhong, Department of Otolaryngology, Wuxi Chinese Hospital Allergy is an abnormal reaction of the body to one or more otherwise harmless substances. The main reason for this is that allergic patients produce an excess of antibody-immunoglobulin E (lgE), which interacts with some substances in the environment (allergens) and stimulates the body to release an excess of chemicals, causing allergy symptoms. Obviously, it is important to clarify which allergen is causing the allergy symptoms. By reducing or disengaging from contact with the allergen is the primary component of treating allergic rhinitis. Parents of atopic individuals should be educated that avoiding allergen exposure during infancy and early childhood can help reduce the production of allergenic proteins and even make the allergen-sensitized state disappear. In children with positive skin test mites at an average age of 2.5 years, 58% of the skin tests became negative after 2 years. The children who became negative were mostly exposed to daily allergen concentrations of less than 2 µg/g. Measures to avoid allergen exposure: House dust mites: wrap mattresses, bed frames and pillows in anti-allergen sheaths; wash sheets weekly in hot water (54 degrees or higher); reduce indoor humidity to less than 50%; clean the room thoroughly; replace duvets and pillows with synthetic material products; wash and clean bed toys weekly; install high-efficiency air filter devices; and do not use upholstered furniture. Pollen: Close doors and windows of the house; reduce outdoor activities during pollen transmission season; install high-efficiency air filters. Allergen testing is currently carried out in the otolaryngology departments of major hospitals in the city. The Wuxi Hospital of Traditional Chinese Medicine also conducts allergen testing on Sunday mornings for the convenience of student patients.
