摘 要:目的:观察上海闵行地区2010-2012年老年慢性阻塞性肺疾病急性发作期(acute exacerbations of chronic obstructive pulmonary disease, AECOPD )患者病毒感染情况,探讨老年AECOPD病毒感染的相关临床特征。方法选择2010年9月至2012年11月复旦大学附属上海市第五人民医院呼吸科70岁以上老年AECOPD住院患者为研究对象,并排除不能配合肺功能检查的患者。所有患者均采集鼻咽拭子,采用多重巢式PCR检测9种呼吸道病毒及其不同亚型,包括A型流感病毒(FluA)、2009甲型流感病毒(09FluH1)、B型流感病毒(FluB)、呼吸道合胞病毒A型(RSVA)和 B 型(RSVB)、人冠状病毒229E 型(hCOV-229E)、NL-63型(hCOV-NL63)、OC43型(hCOV-OC43)和 HKU1型(hCOV-HKU1)、人副流感病毒1~4型(hPIV1、hPIV2、hPIV3、hPIV4)、腺病毒(hAdV)、博卡病毒(HBoV)、人类偏肺病毒(hMPV)、鼻病毒(hRV)等。根据检测结果将所有病例分为病毒感染组和非病毒感染组,分析病毒感染与AECOPD临床特征的关系。结果入选的60例患者中14例病毒检测阳性,阳性率为23.33%,其中一例为三重感染(FluB、hRV和 hCOV)。检出病毒为9例 hRV (15.00%)、2例 hPIV (3.33%)、2例 hCOV (3.33%)、2例FluB (3.33%)、1例RSV (1.67%)。通过比较两组之间的临床特征,发现病毒感染组病死率高于非病毒感染组,其余一般情况、症状、体征、化验检查和住院时间方面两组之间差异无统计学意义。结论鼻病毒是老年AECOPD患者呼吸道检出最多的病毒。老年AECOPD患者呼吸道病毒感染影响预后,且临床表现缺乏特异性,快速诊断上存在一定困难。Objective To investigate the epidemiology of viral infection in elderly patients to contract acute exacerbations of chronic obstructive pulmonary disease (AECOPD)in Minhang district of Shanghai from 2010 to 2012,and to study the relationships between viral infection and clinical features.Methods The elderly patients (age 〉70 year old)with AECOPD admitted from September 2010 to November 2012 were enrolled for study.The patients who couldn't complete lung function test were excluded.The pharyngeal swabs (PS)were taken from each patient within the first 24 h after admission.Nine respiratory viruses and their subtypes from pharyngeal swabs were detected by the nested multiplex polymerase chain reaction (PCR)method,including influenza virus A (FluA),2009 influenza A (H1N1 )virus (09FluH1 ), influenza virus B (FluB),respiratory syncytial virus A (RSVA)and B (RSVB),human coronavirus-229E (hCOV-229E),human coronavirus-NL63 (hCOV-NL63 ),human coronavirus-OC43 (hCOV-OC43 ), human coronavirus-HKU1 (hCOV-HKU1),human parainfluenza virus 1-4 (hPIV1-4),human adenovirus (hAdV),human boca virus (hBoV),human metapneumo-virus (hMPV)and human rhinovirus (hRV). According to the PCR results,all patients were divided into positive viral infection group and negative viral infection group.The relationships between viral infection and clinical features were analyzed.Results Sixty patients were eligible for study.Of them,14 patients were found to be positive for virus infection including a triple infected patient (FluB,hRV and hROV)and 46 patients were negative for virus infection.The viral pathogens detected in the positive viral group were:9 cases of hRV (15.00%),2 cases of hPIV (3.33%),2 cases of hCOV (3.33%),2 cases of FluB (3.33%)and 1 cases of RSV (1.67%).The mortality in the positive viral group was higher than that in the negative viral group.However,the other clinical characteristics between the two groups had no significa
