小儿免疫功能低下,极易患各种感染性疾病,其中反复呼吸道感染较为常见,如何提高这部分患儿的免疫功能,减少他们感染次数,减轻感染程度,缩短疗程是儿科医务工作者面临的课题。支气管哮喘是目前最常见的慢性气道炎症性疾病,近年来报道患病率及病死率均有上升趋势,尤其儿童患病率增高较明显。吸入疗法虽可有效改善患儿的生存质量,但进一步的治疗,减少复发、减少合并感染机会仍是患儿及家长的迫切要求。卡介苗素注射液是一种免疫调节剂,具有增强和调节机体细胞和体液免疫,刺激网状内皮系统,激活单核巨噬细胞系统等功能,对预防感染具有重要作用。我科自2000年开始,应用卡介苗素,对反复呼吸道感染的病例及哮喘患儿均取得较好疗效,报告如下。1对象和方法
Infantile immunocompromised and susceptible to a variety of infectious diseases, including recurrent respiratory infections are more common, how to improve this part of children’s immune function, reduce their frequency of infection, reduce the level of infection, shorten the course of treatment is the subject of pediatric medical workers . Bronchial asthma is the most common chronic airway inflammatory disease. In recent years, the prevalence and mortality have been on the rise, especially in children. Although inhaled therapy can effectively improve children’s quality of life, further treatment, reduce recurrence and reduce the chance of infection are still urgent needs of children and parents. BCG injection is an immunomodulator with functions of enhancing and regulating the cellular and humoral immunity, stimulating the reticuloendothelial system and activating the monocyte-macrophage system, and plays an important role in preventing infection. My department since 2000, the application of BCG, recurrent respiratory tract infections and asthma in children have achieved good results, the report is as follows. 1 object and method
