Abstract

Background: Human rhinovirus (HRV) and human metapneumovirus (hMPV) are common viral causes of pediatric respiratory tract infections. Bacterial co-infections frequently complicate HRV and hMPV illnesses in children, but the interactions between viral and bacterial pathogens and their impacts on disease severity are not well understood. Objectives: The present research aimed to analyze and compare the clinical features of HRV and hMPV mono-infections in hospitalized children and to assess the impact of bacterial co-infection on the disease severity of HRV and hMPV infections. Methods: The present retrospective analytical cross-sectional study was conducted to compare the clinical features between HRV and hMPV mono-infections and HRV and hMPV with bacterial co-infections in hospitalized children aged 14 years or younger. Results: Between January and December 2022, we investigated 1,978 children hospitalized with HRV infection, of which 1,529 had HRV mono-infection and 1,117 hospitalized with hMPV infection, among whom 910 had hMPV mono-infection. Compared to HRV, hMPV mono-infection exhibited more pronounced symptoms of fever, cough, and rales in most age groups, while HRV showed more wheezing. Except in patients ≥ 6 years old, hMPV was more associated with pneumonia and longer hospitalizations. In contrast to HRV mono-infections, children with bacterial co-infections had a higher proportion of coughs (P < 0.001), pneumonia (P < 0.001), pediatric intensive care unit (PICU) admissions (P < 0.001), and longer hospitalizations (P = 0.003). Demographic characteristics, clinical presentation, diagnosis, and treatments showed no significant differences between patients with hMPV mono-infection and co-infection. Conclusions: Among hospitalized children, hMPV mono-infection resulted in more severe respiratory illnesses compared to HRV mono-infection. Bacterial co-infections exacerbated disease severity in HRV infections.
细菌合并感染对人鼻病毒和人偏肺病毒感染住院儿童的影响:回顾性分析横断面研究
背景:人鼻病毒(HRV)和人偏肺病毒(hMPV)是引起小儿呼吸道感染的常见病毒。细菌合并感染经常使儿童HRV和hMPV疾病复杂化,但病毒和细菌病原体之间的相互作用及其对疾病严重程度的影响尚不清楚。目的:本研究旨在分析和比较住院儿童HRV和hMPV单感染的临床特征,并评估细菌共感染对HRV和hMPV感染病情严重程度的影响。方法:回顾性分析横断面研究,比较14岁及以下住院儿童HRV和hMPV单一感染及HRV和hMPV合并细菌感染的临床特点。结果:2022年1 - 12月,我们调查了1978例HRV感染住院儿童,其中1529例为HRV感染,1117例为hMPV感染,其中910例为hMPV感染。与HRV相比,hMPV单一感染在大多数年龄组中表现出更明显的发烧、咳嗽和啰音症状,而HRV则表现出更多的喘息。除6岁以上的患者外,hMPV与肺炎和住院时间更长相关。与单纯HRV感染相比,合并细菌感染的儿童咳嗽的比例更高(P <0.001),肺炎(P <0.001),儿科重症监护病房(PICU)入院率(P <0.001),住院时间更长(P = 0.003)。人口统计学特征、临床表现、诊断和治疗在hMPV单一感染和合并感染患者之间无显著差异。结论:在住院儿童中,单hMPV感染比单HRV感染导致更严重的呼吸道疾病。细菌合并感染加重了HRV感染的疾病严重程度。
