摘要

Recurrent respiration tract infection (RRTI) is a common respiratory disease in children.Immunocompromise, congenital malformation, nutritional deficiency, chronic disease, and incomplete treatment of infection disease, etc, are the common causes of this disease. Research showed that RRTI was related to the changes of bronchial mucosa immunity, airway hyperreactivity, and allergies.%反复呼吸道感染(recurrent respiration traet infection,RRTI)是儿童常见的呼吸道疾病,常见的原因有免疫功能低下、先天畸形、营养物质缺乏、慢性疾病以及感染疾病治疗不彻底等.RRTI与呼吸道黏膜免疫改变、气道高反应性及过敏有关.
