摘要
目的了解湖南长沙地区重症肺炎患儿中呼吸道病毒的感染状况。方法2011年1月至2011年12月,收集重症肺炎儿童的肺泡灌洗液标本122份,采用巢氏或普通逆转录聚合酶链反应(nested-PCR或RT—PCR)对腺病毒(ADV)、博卡病毒(HBoV)及副流感病毒1、2和4(PIV1、2、3、4)、呼吸道合胞病毒(RSV)、鼻病毒(HRV)、流感病毒A、B(IFVA—B)、人偏肺病毒(HMPV)、冠状病毒HKUl及NL63(HCoV-HKU1、HCoV.NL63)进行检测。结果122份重症肺炎患儿肺泡灌洗液标本中,60份病毒阳性(49.1%),其中ADV检出率最高(40.98%,50/122),其次为RSV(7.37%,9/122),HBoV(7.37%,9/122)。2种病毒混合感染有21例,占35%(21/60),40%(20/50)的ADV阳性存在混合感染。结论2011年,腺病毒感染是长沙地区重症肺炎的重要病因,其中腺病毒的混合感染在重症肺炎中常见。
Objective To investigate the prevalence of viral pathogen in children with severe pneumonia in Hunan. Method Bronchoalveolar lavage fluid[ BALF] were collected from 122 hospitalized children with severe pneumonia in People's Hospital of Hunan province from January 2011 to December 2011. Nestedor reverse transcription Polymerase chain reaction (PCR or RT-PCR)was used to screen Adenovirus ( ADV ) , Human Bocavirus ( HBoV ) , Parainfluenzavirusesl-4 ( PIV1-4 ) , Human Respiratory Syneytial virus(RSV) , Influenza virus A (IFVA) , Influenza virus B (IFVB) , Human Rhinovirus(HRV) , Human Metapneumovirus (HMPV) ,human eoronaviruses NL63 and HKU1 ( HCoV-NL63, HCoV- HKU1 ). Results Among the 122 bronehoalveolar lavage fluid, viral agents were detected in 60 samples(49. 1% ) , among which ADV (40.98%) was the most common virus, followed by RSV (7.37%) and HBoV (7.37%). Two viruses were detected in 21 individual(35% ) samples,of which 20 were dual positive for ADV (40%). Conclusion ADV is the most frequently detected viral etiology of severe pneumonia in children in Hunan during this year. And its Coinfection with other respiratory viruses was common.
