Respiratory syncytial virus (RSV) is the leading viral pathogen associated with acute lower respiratory tract infection and hospitalization in children < 5 years of age worldwide. While there are known clinical risk factors for severe RSV infection, the majority of those hospitalized are previously healthy infants. There is consequently an unmet need to identify biomarkers that predict host response, disease severity, and sequelae. The primary objective is to identify biomarkers of severe RSV acute respiratory tract infection (ARTI) in infants. Secondary objectives include establishing biomarkers associated with respiratory sequelae following RSV infection and characterizing the viral load, RSV whole-genome sequencing, host immune response, and transcriptomic, proteomic, metabolomic and epigenetic signatures associated with RSV disease severity. Six hundred thirty infants will be recruited across 3 European countries: the Netherlands, Spain, and the United Kingdom. Participants will be recruited into 2 groups: (1) infants with confirmed RSV ARTI (includes upper and lower respiratory tract infections), 500 without and 50 with comorbidities; and (2) 80 healthy controls. At baseline, participants will have nasopharyngeal, blood, buccal, stool, and urine samples collected, plus complete a questionnaire and 14-day symptom diary. At convalescence (7 weeks ± 1 week post-ARTI), specimen collection will be repeated. Laboratory measures will be correlated with symptom severity scores to identify corresponding biomarkers of disease severity.

严重呼吸道合胞病毒疾病和相关后遗症的假定危险因素和生物标记物:来自欧洲呼吸道合胞病毒联盟(RESCEU)的观察性多中心病例对照研究的方案。

呼吸道合胞病毒(RSV)是与急性下呼吸道感染相关的主要病毒病原体,并在全球范围内对5岁以下儿童进行住院治疗。尽管存在严重RSV感染的已知临床危险因素,但大多数住院患者是先前健康的婴儿。因此,识别预测宿主反应,疾病严重程度和后遗症的生物标志物的需求未得到满足。主要目的是鉴定婴儿严重RSV急性呼吸道感染(ARTI)的生物标志物。次要目标包括建立与RSV感染后呼吸系统后遗症相关的生物标志物,并表征病毒载量,RSV全基因组测序,宿主免疫反应以及与RSV疾病严重程度相关的转录组学,蛋白质组学,代谢组学和表观遗传学特征。将在三个欧洲国家(荷兰,西班牙和英国)招募630名婴儿。参加者将分为2组:(1)确诊为RSV ARTI的婴儿(包括上呼吸道和下呼吸道感染),500例无合并症和50例合并症;(2)80名健康对照者。在基线时,参与者将收集鼻咽,血液,颊,粪便和尿液样本,并填写问卷和14天症状日记。恢复期(ARTI后7周±1周),将重复收集标本。实验室措施将与症状严重程度评分相关联,以识别疾病严重程度的相应生物标志物。参加者将分为2组:(1)确诊为RSV ARTI的婴儿(包括上呼吸道和下呼吸道感染),500例无合并症和50例合并症;(2)80名健康对照者。在基线时,参与者将收集鼻咽,血液,颊,粪便和尿液样本,并填写问卷和14天症状日记。恢复期(ARTI后7周±1周),将重复收集标本。实验室措施将与症状严重程度评分相关联,以识别疾病严重程度的相应生物标志物。参加者将分为2组:(1)确诊为RSV ARTI的婴儿(包括上呼吸道和下呼吸道感染),500例无合并症和50例合并症;(2)80名健康对照者。在基线时,参与者将收集鼻咽,血液,颊,粪便和尿液样本,并填写问卷和14天症状日记。恢复期(ARTI后7周±1周),将重复收集标本。实验室措施将与症状严重程度评分相关联,以识别疾病严重程度的相应生物标志物。并填写问卷和14天的症状日记。恢复期(ARTI后7周±1周),将重复收集标本。实验室措施将与症状严重程度评分相关联,以识别疾病严重程度的相应生物标志物。并填写问卷和14天的症状日记。恢复期(ARTI后7周±1周),将重复收集标本。实验室措施将与症状严重程度评分相关联,以识别疾病严重程度的相应生物标志物。
