社区获得性肺炎住院患儿混合感染研究进展

摘要

Community acquired pneumonia ( CAP) is the most common respiratory infectious disease in hospitalized children. With the development of etiology detection technology, the detection rate of CAP pathogens has rose significantly, and meanwhile the co-infections of multiple pathogens have been paid more at-tention gradually. The combinations of co-infection agents are in a diverse way. There is not a unified under-standing about the impact on the severity of disease. The mechanism of co-infection and risk factors remain un-clear. These have brought great difficulties for clinical diagnosis and treatment. This review provides an over-view of the current situation, pathogen combination, age and seasonal characteristics, clinical features, the impact on the severity of disease, risk factors, treatment and so on in CAP hospitalized children with co-infec-tion.%社区获得性肺炎(community acquired pneumonia,CAP)是儿童住院最常见的呼吸道感染性疾病.随着病原学检测技术的发展,CAP病原检出率明显提高,同时多病原体的混合感染也逐步受到重视.混合感染的病原组合多种多样,对疾病的影响目前尚无统一认识,混合感染的机制及危险因素尚不明确,给临床诊治带来了较大的困难.该文就儿童社区获得性肺炎住院患儿混合感染的现状、病原构成、年龄及季节特征、临床特征、对疾病严重程度的影响、高危因素、治疗等进行综述.
