[Expert consensus on joint diagnosis and treatment of multimorbidity of upper airway allergic diseases in children].

Objective:Upper airway allergic diseases in children refer to chronic non-infectious inflammatory diseases of the upper airway caused by allergic inflammation. These diseases have high prevalences and great harm, furthermore often co-occur. Focusing only on the treatment of individual diseases may lead to ineffective control. To more comprehensively and effectively relieve symptoms and signs, and prevent recurrence or prolongation, pediatric upper airway allergic diseases must be diagnosed and treated jointly as an entity. Although there are currently several guidelines and consensuses on diagnosis and treatment of single pediatric upper airway allergic diseases, there is still a lack of expert consensus on the integrated diagnosis and treatment of multimorbidity. Therefore, the Pediatric Otorhinolaryngology and Head and Neck Surgery Committee of the Chinese Association for the Promotion of Human Health Science and Technology organized multidisciplinary experts to develop this consensus based on clinical experience and evidence-based medicine, aiming to guide the joint diagnosis and treatment of multimorbidity of upper airway allergic diseases in children in clinical practice.
