Objectives

To determine the association between viral species and odds of severe lower respiratory tract illnesses (sLRI) versus upper respiratory illness (URI) among children under 2 years of age.

Methods

Infants (n=2061) enrolled in the Puerto Rican Infant Metagenomic and Epidemiologic Study of Respiratory Outcomes were surveilled for respiratory illnesses until age 2 years (March 2020 to April 2024). Nasal swabs from 1363 illnesses (774 participants) were screened for 21 pathogens.

Results

RSV infections occurred in 23% of sLRIs and increased odds of sLRI vs URI (OR=9.28; 95% CI, 5.43–15.85). Metapneumovirus, parainfluenza, and non-SARS-CoV-2 coronavirus also increased odds of sLRIs, while SARS-CoV-2 was associated with lower risk of sLRIs. Rhinovirus (43%) and bocavirus (16.1%) were commonly detected, but were not associated with sLRI risk. Co-infection with multiple viral species was associated with 2.92-fold greater odds of sLRI (95% CI, 2.05–4.16) compared to single viral species infections. Rhinovirus-bocavirus was the most common co-infection, and interaction between these viruses was associated with increased odds of sLRI.

Conclusions

Diverse viral pathogens drive early-life sLRIs. Some (e.g. RSV and metapneumovirus) have an intrinsic propensity to cause sLRIs, while other viruses’ lower airway pathogenicity depends on other factors, including co-infection.
目的:确定病毒种类与2岁以下儿童严重下呼吸道疾病(sLRI)和上呼吸道疾病(URI)发病率之间的关系。方法:参与波多黎各婴儿呼吸结局宏基因组学和流行病学研究的婴儿(n= 2061)在2岁之前(2020年3月至2024年4月)接受呼吸疾病监测。对来自1363名患者(774名参与者)的鼻拭子进行了21种病原体筛查。结果:23%的sLRI发生RSV感染,sLRI与URI的几率增加(OR=9.28; 95% CI, 5.43-15.85)。偏肺病毒、副流感病毒和非SARS-CoV-2冠状病毒也增加了sLRIs的几率,而SARS-CoV-2冠状病毒与sLRIs的风险较低相关。鼻病毒(43%)和bocavavirus(16.1%)常被检测到,但与sLRI风险无关。与单一病毒种感染相比,多重病毒种合并感染sLRI的几率高出2.92倍(95% CI, 2.05-4.16)。鼻病毒-博卡病毒是最常见的合并感染,这些病毒之间的相互作用与sLRI的几率增加有关。结论:不同的病毒病原体驱动早期slri。一些病毒(如RSV和偏肺病毒)具有引起sLRIs的内在倾向,而其他病毒的低气道致病性取决于其他因素,包括合并感染。

Background

Shotgun metagenomics (SMg) promises to significantly improve the microbiological diagnosis of infectious diseases. However, the prospective evaluation of its clinical utility in different infectious syndromes remains poorly documented.

Methods

We conducted a prospective study including all patients who underwent SMg as part of their care at the French Henri Mondor Hospital National Reference Laboratory for accredited SMg between February 2018 and January 2020. Patients were categorized as having either a "high likelihood" or "low likelihood" of infection based on their clinical presentation. The contribution of the SMg to the final diagnosis was assessed by a multidisciplinary team of infectious disease specialists.

Findings

202 patients were enrolled in the study. Of the 123 patients considered to have a high likelihood of infection, SMg confirmed the cause of infection in 38 cases (30.9%), including 12 cases (9.8%) diagnosed exclusively by this method. In the 79 patients classified as having a "low likelihood" of infection, SMg did not detect any microorganisms compatible with an infectious cause. In particular, patients undergoing immunosuppressive treatment within the latter group showed no deterioration after 6 months.

Interpretation

SMg facilitated microbiological diagnosis in over 30% of complex cases, regardless of sample type or site of infection. Compared with conventional techniques, SMg provided diagnoses in 10% more cases, highlighting its broad utility across different infectious diseases. Our results suggest that SMg is a promising tool for documenting complex infectious diseases alongside traditional microbiology tools. Furthermore, negative SMg results are useful for the management of patients with a low likelihood of infection.
背景:霰弹枪宏基因组学(SMg)有望显著改善传染病的微生物学诊断。然而,其在不同感染综合征的临床应用的前瞻性评价仍然缺乏文献记录。方法:我们进行了一项前瞻性研究,包括2018年2月至2020年1月期间在法国亨利蒙多医院国家参考实验室接受SMg治疗的所有患者。根据患者的临床表现,将其分为“高可能性”或“低可能性”感染。由传染病专家组成的多学科小组评估了SMg对最终诊断的贡献。结果:202例患者入组研究。在123例被认为有高感染可能性的患者中,有38例(30.9%)被SMg确诊为感染原因,其中12例(9.8%)是完全通过这种方法诊断的。在79名被归类为“低可能性”感染的患者中,SMg未检测到任何与感染原因相容的微生物。特别是后一组接受免疫抑制治疗的患者在6个月后没有出现恶化。解释:无论样本类型或感染部位如何,SMg有助于超过30%的复杂病例的微生物学诊断。与传统技术相比,SMg提供的诊断病例多10%,突出了其在不同传染病中的广泛应用。我们的研究结果表明,SMg是一种很有前途的工具,可以与传统的微生物学工具一起记录复杂的传染病。此外,阴性SMg结果对低感染可能性患者的管理是有用的。资助:本研究作为患者护理的一部分进行。

Introduction

Metagenomic next-generation sequencing (mNGS) is an important tool for enhancing pathogen detection in infected patients. However, distinguishing between specimens that are infected or colonized is still a major challenge.

Objectives

To explore the composition of bacteriophages in the blood and respiratory tract of the human body, the association between bacteriophage detection and bacterial infections, and whether bacteriophages can assist in differentiating infectious pathogens according to mNGS results.

Methods

Clinical samples from hospitalized patients were collected between January 2023 and February 2024. DNA and cell-free DNA were extracted from BALF and plasma retrospectively to identify the pathogens present, and bacteriophage annotations were conducted.

Results

A total of 299 samples, comprising 136 blood samples and 163 BALF samples, were obtained from 218 patients. Compared with the samples negative for bacteria, both blood and bronchoalveolar lavage fluid (BALF) samples infected with Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and S. aureus showed a corresponding increase in the proportions of phages related to these pathogens. In BALF samples with Acinetobacter baumannii infection, the proportions of Autographiviridae, Siphoviridae, and Myoviridae were significantly greater than those in the Acinetobacter baumannii colonization group. The sensitivity of Myoviridae for differentiating between infection and colonization was 86.36%, and the specificity was 52.94%.

Conclusion

In sepsis, compared with conventional mNGS methods alone, the use of bacteriophages combined with mNGS was more effective in identifying causative pathogens and had higher specificity. These findings may provide new ideas and tools for improving clinical infection diagnosis.
新一代宏基因组测序(mNGS)是加强感染患者病原体检测的重要工具。然而,区分感染或定植的标本仍然是一项重大挑战。目的:探讨人体血液和呼吸道中噬菌体的组成,噬菌体检测与细菌感染的关系,以及根据mNGS结果,噬菌体是否能协助鉴别感染性病原体。方法:收集2023年1月至2024年2月住院患者的临床样本。从BALF和血浆中回顾性提取DNA和游离DNA,鉴定存在的病原体,并进行噬菌体注释。结果:218例患者共获得299份样本,其中血液样本136份,BALF样本163份。与细菌阴性的样本相比,感染鲍曼不动杆菌、肺炎克雷伯菌、铜绿假单胞菌和金黄色葡萄球菌的血液和支气管肺泡灌洗液(BALF)样本显示,与这些病原体相关的噬菌体比例相应增加。在鲍曼不动杆菌感染的BALF样本中,自噬病毒科、虹膜病毒科和肌病毒科的比例显著高于鲍曼不动杆菌定殖组。肌病毒科区分感染与定植的敏感性为86.36%,特异性为52.94%。结论:在脓毒症中,与单独使用常规mNGS方法相比,噬菌体联合mNGS方法对病原菌的识别更有效,特异性更高。这些发现可能为提高临床感染诊断水平提供新的思路和工具。

Background

During the winter, healthcare systems experience additional pressures due to increases in respiratory infections and staff absence. We aimed to determine the prevalence of respiratory viruses and impact on sickness absence in the SIREN healthcare worker (HCW) cohort during winter 2023/24.

Methods

SIREN is a cohort study with linked testing, vaccination, demographic, symptoms and sick leave data. Participants undergo fortnightly multiplex PCR testing for SARS-CoV-2, influenza and RSV, regardless of symptoms. The proportion of participants who took sick leave, the total number and median of sick leave days taken was calculated, overall and stratified by viral infection and vaccination status. Logistic regression was used to estimate the association between sick leave and vaccination status.

Results

A total of 5287 participants were included, 78·3% female, median age 54 years. There were 1828 infections (1161 SARS-CoV-2; 387 RSV; 280 influenza infections) among 1659 participants. Influenza and RSV peaked in December (1·2%; 1·9%), SARS-CoV-2 peaked in September and December 2023 (4·0%; 4·3%).
Regardless of a known infection, 35.8% (1892/5287) took sick leave, resulting in 10,168 days (median 5 days per person; range 1–98 days).

Discussion

Respiratory illness caused a substantial burden on the SIREN healthcare workforce over winter, with all three viruses contributing. Reduced number of staff at work and pressures to work through illness have implications for healthcare resilience.
背景:在冬季,由于呼吸道感染和工作人员缺勤的增加,卫生保健系统面临额外的压力。我们的目的是确定2023/24年冬季SIREN医护人员(HCW)队列中呼吸道病毒的流行率及其对缺勤的影响。方法:SIREN是一项队列研究,包括相关的检测、疫苗接种、人口统计学、症状和病假数据。无论症状如何,参与者每两周接受一次SARS-CoV-2、流感和RSV多重PCR检测。根据病毒感染和疫苗接种状况,计算了请病假的参与者的比例、病假天数的总数和中位数。使用Logistic回归来估计病假与疫苗接种状况之间的关联。结果:纳入5287例受试者,女性78.3%,中位年龄54岁。在1,659名参与者中,有1,828例感染(1,161例SARS-CoV-2; 387例RSV; 280例流感感染)。流感和RSV高峰在12月(1.2%;1.9%),SARS-CoV-2高峰在9月和12月(4.0%;4.3%)。无论是否有已知感染,35.8%(1892 / 5287)的人请了病假,总共请了10168天病假(平均每人5天,范围1-98天)。讨论:呼吸系统疾病在冬季给SIREN医护人员造成了沉重的负担,这三种病毒都起到了作用。工作人员数量的减少和带病工作的压力对医疗弹性有影响。资助:英国卫生安全局、英国卫生和社会保障部,北爱尔兰、威尔士和苏格兰政府提供资助,并提供惠康基金参考。
