280例儿童社区获得性肺炎住院患儿病毒病原学研究

摘要

Objective To investigate the viral pathogens of children with community acquired pneumonia (CAP) in dalian city dur-ing the last year in hospital ,and provide evidences to clinical empirical therapy. Methods Some patients of department of respiratory, in Dalian children' s hospital were derided into four groups from May 2007 to 2008. Serum virus antibodies were detected after 1 week of nat-ural course of disease. Results In 280 cases who were detected for viral lgM antibodies, the positive rate was 28.2%. It was mainly con-sist with respiratory syncytial virus, adenovirus, and parainfluenza virus. The ratio of virus infection in school age group (54.0%) was higher than that in other groups. The second is in toddler age. Conclusion Virus are significant pathogens in CAP of children. The most common viral agent is respiratory syncytial virus (RSV), and the next one is adenovirus (ADV). The ratio of virus infection in school age group is the highest. We should give anti - virus and propotional supportive treatment to these children promptly.%目的 分析280例儿童社区获得性肺炎(CAP)住院患儿病毒病原感染状况,为临床经验性治疗提供依据.方法 选取2007年5月～2008年5月间于大连市儿童医院住院的CAP患儿280例,采取自然病程7～10天时血清标本进行6种常见病毒的IgM抗体检测.6种病毒包括:呼吸道合胞病毒(RSV)、流感病毒(IFV)、副流感病毒(PFV)、腺病毒(ADV)、EB病毒(EBV)和柯萨奇病毒(COX).结果 280例患儿病毒病原学检测阳性79例,占28.2%;阳性病毒构成比中,以RSV为主,占34%,其次是ADV,占30%,PFV占20%;学龄期阳性率为54.0%,明显高于其他年龄组,其次是幼儿组(31.4%).结论 病毒感染仍为本地区儿童CAP的重要致病原,且RSV感染最为常见,其次是ADV及PFV;学龄期血清病毒IgM抗体检测阳性率最高,对此类患儿应注意及时抗病毒治疗.
