摘    要:目的了解新型呼吸道病毒在PICU中的检出情况及感染患儿的临床特点。方法收集我院600例PICU急性呼吸道感染患儿的咽拭子标本600份,87例社区健康体检儿童咽拭子87份作为健康对照。应用多重PCR技术对新型呼吸道病毒进行检测,部分阳性结果进行基因测序,并分析阳性病例的临床资料。结果(1)600例患儿中,新型呼吸道病毒检测阳性114例(19%),其中人博卡病毒(humanbocavirus,HBoV)48例(8.00%),C型鼻病毒(humanrhinovirusgroupC,HRV—C)47例(7.83%),新型甲型流感H1N1病毒13例(2.17%),人偏肺病毒(humanmetapneumovirs,HMPV)10例(1.67%),wu多瘤病毒3例(0.50%)。87例健康儿童呼吸道病毒检测均为阴性。(2)114例新型呼吸道病毒检测阳性患儿中,单一感染69例,混合感染45例,其中HBoV混合其他病毒感染22例(45.83%,22/48),HRV—C混合其他病毒感染14例(29.78%,14/47),新型甲型流感H1N1病毒混合其他病毒感染4例(4/13),HMPV混合其他病毒感染9例(9/10),wu多瘤病毒混合其他病毒感染3例(3/3)。结论PICU中HBoV、HMPV、HRV—C、新型甲型流感H1N1病毒等新型呼吸道病毒具有较高的检出率,可能导致重症感染,应该引起临床重视。

Abstract:Objective To describe the detection and clinical characterization of emerging respiratory virus in PICU. Methods Nasopharyngeal aspirates specimens (NPA) were collected from 600 children who were admitted to PICU with acute respiratory tract infection in our hospital. Additional 87 NPA were collected from healthy children for routine examination in the physical examination center. The clinical datas were collected. Multiplex PCR was applied to detect emerging respiratory virus. Some sequences were identified by using DNA sequencing. And the clinical data of positive cases were analysed. Results ( 1 ) There were 114 positive samples ( 19 % ) in 600 NPA, including 48 ( 8.00% ) human bocavirus (HBoV) ,47 (7.83 % ) human rhinovirus group C(HRV-C), 13 (2. 17% ) swine H1N1 ( SWH1N1 ), 10( 1.67% ) human metapneumovirs (HMPV) ,3 (0. 50% ) WU polyomaviruses (WUPyV). But none from 87 healthy controls were positive for any respiratory virus. (2) Co-infection by at least 2 viral pathogens under study was observed in 45 of the 114 positive cases, including 22 ( 45.83% , 22/48 ) HBoV, 14 ( 29. 78% , 14/47 ) HRV-C, 4 ( 4/13 ) SWH1N1,9 ( 9/10 ) HMPV, 3 ( 3/3 ) WU polyomaviruses. Conclusion The emerging viruses, such as HBoV, HMPV, HRV-C, SWH1 N1, have high detection rate in PICU, may lead to severe infection. The clini- cal doctors should pay attention to them.
