摘要 目的了解苏州地区儿童急性呼吸道感染(acute respiratory infection,ARI)的病毒病原情况,指导临床进行诊断与治疗。方法对苏州大学附属儿童医院2005年11月—2007年5月间住院的2492例ARI患儿采用无菌负压吸引法采集新鲜痰液,采用直接免疫荧光法检测7种病毒,即呼吸道合胞病毒(respirations syncytial virus,RSV),腺病毒(adenovirus,ADV),流感病毒A、B型(influenza virus-A,Inf-A;influenza virus—B,Inf-B),副流感病毒1、2、3型(parainfluenzeviru-1,Pinf-1;parainfluenze viru-2,Pinf-2;parainfluenze viru-3,Pinf-3)。同时用逆转录聚合酶链反应(RT—PCR)法进行人偏肺病毒(human metapneumovirus,hMPV)检测。结果送检标本2492例,总病毒阳性率38.6%(961/2492),总阳性检出率与年龄、季节及病种有关[年龄:各年龄组总病毒检出阳性率分别为:50.0%(412/824),43.4%(190/438),30.5%(207/679)和27.6%(152/551),χ^2=96.5002,P〈0.01;季节:春夏秋冬四季总病毒检出阳性率分别为:46.7%(366/784),13.8%(66/478),13.8%(59/428)和58.6%(470/802),χ^2=392.3279,P〈0.01;病种:各种临床疾病(上呼吸道感染、急性喉炎、喉-气管-支气管炎、支气管肺炎、大叶性肺炎、毛细支气管炎、支气管哮喘)总病毒检出阳性率分别为:21.4%(30/140),73.7%(14/19),32.0%(8/25),36.9%(598/1620),13.1%(8/61),66.1%(216/327)和29.0%(87/300),χ^2=162.1276,P〈0.01],与性别无关[男女总病毒阳性率分别为:39.0%(588/1508)和37.9%(373/984),χ^2=0.2962,P〉0.05],其次为hMPV 20.6%(198/961)。RSV流行高峰主要集中在12—3月份,以毛细支气管炎感染率50.2%(164/327)最高,hMPV全年均可检出,冬季检出率13.2%(106/802)最高。结论RSV和hMPV是苏州地区ARI患儿的主要病毒病原,通过检测儿童呼吸道感染疾病的病毒病原,可对临床提供快速、准确的诊断依据,防止滥用抗生素。 Objective To investigate the pathogen of children with acute respiratory infection (ARI) in Suzhou and to provide some evidences for clinical diagnosis and treatment. Methods The nasopharyngeal secretion samples from 2492 inpatient children with ARI ,during the period of November 2005 to May 2007, were investigated for respiratory syneyeial virus (RSV) , influenza virus A and B, parainfluenza virus type 1,2,3 and adenovirus by both the indirect immunofluorecence assay and virus isolation. Human metapneumovirus (hMPV) were examined by reverse-transcription polymerase chain reaction (RT-PCR) at the same time. Results Of 2492 samples tested,961 (38.6%) were positive. The total positive rate of virus pathogens in children with ARI was found related to age, season and respiratory disease. The detection rates by age were : 50. 0% (412/824), 43.4% ( 190/438 ), 30. 5% ( 207/679 ) and 27.6% ( 152/551 ), χ^2 = 96. 5002,P 〈0.01 ;the detection rates by season were : 46. 7% (366/784) ,13.8% (66/478) ,13.8% (59/ 428)and 58. 6% (470/802), χ^2 = 392. 3279, P 〈 0. 01 ; the detection rates by disease were ( acute upper respiratory infection, acute laryngitis, throat-trachea-bronchitis, bronchial pneumonia, pneumonia genuina, bronchiolitis, bronchial asthma) :21.4% ( 30/140 ) ,73.7 % ( 14/19 ), 32. 0% ( 8/25 ), 36.9% ( 598/1620 ), 13.1%(8/61),66.1% (216/327) and 29. 0% (87/300), χ^2 = 162. 1276, P〈 0.01. There was no association between the total positive rate and sex. The detection rates by sex were: 39. 0% (588/1508) formale and 37.9% (373/984) for female,χ^2 = 0. 2962,P 〉0. 05. The peak of RSV appeared from December to March. There was the highest RSV detection rate 50. 2% ( 164/327 ) with bronchiolitis. The hMPV can be detected all year around. The peak of hMPV appeared in winter and the detection rate was 13. 2% ( 106/ 802). Conclusion RSV and hMPV are the main respiratory viral pathogens in Suzhou. Detection of viral pathogens in children with respiratory infection could give fast, accurate diagnostic evidence, and help avoid antibiotics abuse.
