老年呼吸道感染患者9项呼吸道病原体感染状况分析

Infections of nine respiratory tract pathogens in elderly patients

目的探讨黄石市中心医院住院老年肺部感染患者呼吸道9项病原体的感染情况,为临床诊断治疗提供依据。方法收集2011年5月至2014年5月黄石市中心医院收治的3032例住院的老年呼吸道感染患者住院当天的血清,采用间接免疫荧光法检测呼吸道感染9项病原体的Ig M抗体。结果 9项呼吸道病原体检出阳性者共1166例,占38.46%(1166/3032),其中单项呼吸道病原体感染1151例,占98.71%。阳性患者中感染肺炎支原体(MP)占70.28%(809/1151),腺病毒(ADV)占10.69%(123/1151),乙型流感病毒(Flu B)占6.95%(80/1151),呼吸道合胞病毒(RSV)和副流感病毒(PIV)分别占6.60%(76/1151)及3.56%(41/1151),甲型流感病毒(Flu A)仅占1.91%(22/1151)。未发现Q热立克次体(COX)、嗜肺军团菌(LP)和肺炎衣原体(CP)感染者。结论 MP、ADV为黄石地区老年肺部感染患者呼吸道非细菌性病原体感染的主要致病原。对疑难病例早期进行9项呼吸道病原体联合检测,可以为临床提供病原学诊断,使患者得到及时治疗。

Objective To investigate the infection status of admitted elderly patients infected with 9 respiratory tract infection pathogens in hospitalized elderly patients from May 2011 to May 2014 in Huangshi central hospital. Methods The serum samples were obtained from 3032 hospitalized elderly patients with acute respiratory tract infection（ ARI）. Ig M of 9 respiratory tract infection pathogens was detected by indirect immunofluorescence assay（ IFA）. Results In 3032 cases,the positive detection rate of 9 respiratory tract infection pathogens was 38. 46%（1166 cases）. MP was the most common respiratory infection pathogen found in 809 infection cases（70. 28%）. The account rate of ADV,Flu B,RSV,PIV was 10. 69%,6. 95%,6. 60%,3. 56% respectively. Conclusions MP and Flu B are the primary prevalent pathogens of hospitalized elderly patients with respiratory tract infection in Huangshi. Detection of the 9 types of respiratory tract infection pathogens among the suspected cases is strongly recommended,which is benifical for providing etiological reference for clinical diagnosis.
