Abstract

Background: Bacterial and viral co-infections are increasingly recognized as the cause of Acute Respiratory Infection (ARI). The role of co-infection in ARI patients with Parainfluenza Virus type 3 (PIV3) infection is unclear. Objectives: This study aimed to determine the prevalence of PIV3 co-infections in hospitalized children and assess the co-infections' role in ARI patients with PIV3 infections. Methods: Between January 2018 and December 2021, children were confirmed to have a PIV3 infection via throat swabs or nasopharyngeal aspirates. Some digital clinical data were analyzed, including demographic, epidemiological, diagnostic, and laboratory data. Results: During the study period from 2018 to 2021, 2,539 patients were hospitalized with ARI caused by PIV3. Of them, 34.0% had co-infection with other pathogens, and 2.4% had co-infection with more than two pathogens. Mycoplasma pneumoniae was the most common co-infecting pathogen (71.3%), followed by other bacteria (13.3%) and viruses (8.2%). A significantly higher proportion of patients with M. pneumoniae co-infection was found in girls (χ2 = 19.233, P < 0.001). Co-infections with M. pneumoniae were observed principally in patients aged 1 – 2 years (χ2 = 202.130, P < 0.001). In contrast, viral (56.3%) and bacterial (66.1%) co-infections occurred mainly in children younger than one year. The diagnosis of PIV3 as a single infection included pneumonia (41.2%), bronchitis (39.9%), upper respiratory tract infections (15.0%), and laryngitis (3.9%), which were distinguished from those with bacterial co-infections (χ2 = 16.424, P = 0.001) and co-infections with more than two pathogens (χ2 = 11.687, P = 0.010). Co-infections of PIV3 with any pathogen were not associated with admissions to intensive care units or ventilator support. However, the mean hospitalization was significantly higher in M. pneumoniae co-infections (t = 2.367, P = 0.018), bacterial co-infections (t = 2.402, P = 0.016), and co-infections with more than two pathogens (t = 2.827, P = 0.006) than in single PIV3 infection. Conclusions: Parainfluenza virus type 3 frequently occurs with other pathogens. The epidemiological and clinical characteristics of co-infections with different pathogens differed. Mycoplasma pneumoniae co-infections, bacterial co-infections, and co-infections with more than two pathogens lengthened the hospitalization. Bacterial co-infections and co-infections with more than two pathogens increased the severity of ARI and worsened the symptoms.

武汉市急性呼吸道感染住院儿童中3型副流感病毒与其他呼吸道病原体的联合感染
背景:细菌和病毒合并感染越来越被认为是急性呼吸道感染(ARI)的原因。ARI患者合并副流感病毒3型(PIV3)感染的合并感染的作用尚不清楚。目的:本研究旨在确定住院儿童PIV3合并感染的患病率,并评估合并感染在伴有PIV3感染的ARI患者中的作用。方法:2018年1月至2021年12月期间,通过咽拭子或鼻咽吸痰确认儿童感染PIV3。分析了一些数字临床数据,包括人口统计、流行病学、诊断和实验室数据。结果:2018年至2021年研究期间,2539例因PIV3引起的ARI住院。其中34.0%的患者合并感染其他病原菌,2.4%的患者合并感染2种以上病原菌。肺炎支原体是最常见的共感染病原体(71.3%),其次是其他细菌(13.3%)和病毒(8.2%)。女孩合并肺炎支原体感染的比例明显高于女孩(χ2 = 19.233, P < 0.001)。肺炎支原体合并感染主要发生在1 ~ 2岁的患者中(χ2 = 202.130, P < 0.001)。相比之下,病毒(56.3%)和细菌(66.1%)合并感染主要发生在一岁以下的儿童中。PIV3为单一感染的诊断包括肺炎(41.2%)、支气管炎(39.9%)、上呼吸道感染(15.0%)和喉炎(3.9%),与合并细菌感染(χ2 = 16.424, P = 0.001)和合并两种以上病原体感染(χ2 = 11.687, P = 0.010)有明显区别。PIV3与任何病原体的合并感染与入住重症监护病房或呼吸机支持无关。然而,肺炎支原体合并感染(t = 2.367, P = 0.018)、细菌合并感染(t = 2.402, P = 0.016)和两种以上病原体合并感染(t = 2.827, P = 0.006)的平均住院率显著高于单一PIV3感染。结论:3型副流感病毒常与其他病原体一起发生。不同病原菌合并感染的流行病学和临床特征存在差异。肺炎支原体合并感染、细菌合并感染和两种以上病原体合并感染延长了住院时间。细菌共感染和两种以上病原体的共感染增加了ARI的严重程度并使症状恶化。
