摘要:

目的 了解新型冠状病毒肺炎(COVID-19)患者呼吸道病原体混合感染情况。方法 将500例COVID-19患者分为轻型组(205例)、普通型组(195例)、重型组(65例)和危重型组(35例),采用间接免疫荧光法检测所有COVID-19患者8种常见呼吸道病原体(流感病毒A型、流感病毒B型、副流感病毒、呼吸道合胞病毒、腺病毒、肺炎支原体、肺炎衣原体、嗜肺军团菌)IgM抗体。结果 轻型组、普通型组、重型组、危重型组分别有20、20、12和10例合并呼吸道病毒感染,分别占各组的9.76%、10.26%、18.46%和28.57%,差异有统计学意义(P<0.05)。62例(12.4%)合并呼吸道感染患者中,有26例(5.2%)为多重感染。轻型、普通型、重型、危重型组合并感染率呈递增趋势,差异有统计学意义(P<0.05)。结论 COVID-19患者呼吸道病原体混合感染率与COVID-19严重程度有关,在临床诊疗过程中要注意联合用药,以提高治愈率。

Abstract:

Objective To understand the status of corona virus disease 2019(COVID-19) patients with respiratory tract pathogen mixed infection. Methods Totally,500 patients with COVID-19 were classified into 4 groups,including light group(205 cases),common group(195 cases),severe group(65 cases) and critical group(35 cases). The IgM antibodies of 8 common respiratory tract pathogens in patients with COVID-19 were determined by indirect immunofluorescence,which included influenza A,influenza B,parainfluenza virus,respiratory syncytial virus,adenovirus,Mycoplasma pneumoniae,Chlamydia pneumoniae and Legionella pneumophila IgM. Results The respiratory tract pathogen mixed infection accounted for 9.76%,10.26%,18.46% and 28.57% in light group(20 cases),common group(20 cases),severe group(12 cases) and critical group(10 cases),respectively(P<0.05). The respiratory tract pathogen mixed infection totally accounted for 12.4%(62 cases),of which 26 cases had multiple infections,accounting for 5.2%,showing an increasing trend(P<0.05). Conclusions There are mixed infection in patients with COVID-19. The rate of mixed infection and the severity of COVID-19 are increasing. In the clinical diagnosis and treatment process,it should pay attention to the combined usage of drugs to improve the cure rate.
