PROJECT SUMMARY/ABSTRACT COVID-19, the pandemic illness caused by the novel virus SARS-CoV-2, is a serious respiratory illness that has high infectivity and a mortality rate that varies from <1% to up to 20% depending on underlying risk factors. Indeed, disease severity varies markedly based on recognized clinical risk factors (age and co-morbidities). The biological underpinnings of this clinical variability are unknown but likely relate to variation in both the virus and the host response. A detailed understanding of the risk factors for severe disease, including genetic and environmental factors and the nature of the host immunological response, is essential for the development of prognostic biomarkers and effective therapies. To meet this urgent need we propose to help develop and to participate in the IMPACC multi-center longitudinal clinical study of hospitalized patients with COVID-19 and to immunophenotype participants using shared immunological methods that will be designed an carried out by core laboratories at UCSF and at other participating institutions. Our specific aims are 1) to develop a prospective observational convenience cohort of adult subjects hospitalized with known or presumptive COVID-19, 2) to use this cohort to describe the relationship between specific immunologic assessments and clinical course of COVID-19 in hospitalized patients, and 3) to implement three core laboratories at UCSF to support immunophenotyping in this multicenter cohort. These core laboratories will perform bulk RNA sequencing of blood peripheral blood mononuclear cells (PBMC), bulk metagenomic next-generation sequencing (mNGS) on endotracheal aspirate samples, and serologic phage display assays (PhIP-Seq). Successful completion of these aims will yield critical information regarding the relationship between viral load, host immunological responses, and poor clinical outcomes that are urgently needed for biomarker development and rational therapeutic targeting. In addition, the cellular samples banked in this study may directly contribute to the development of neutralizing antibodies and vaccine strategies that will be our ultimate defense against recurrence of this extraordinary pandemic. A rapid and robust scientific and medical response of the type proposed by the NIAID and the academic community in this consortium is an essential element of a broad response required to protect the health and well-being of all individuals, our health care system, and the broader social structures that maintain global health and welfare.

项目概要/摘要 COVID-19 是由新型病毒 SARS-CoV-2 引起的大流行性疾病，是一种严重的呼吸道疾病， 具有高传染性，死亡率根据潜在的危险因素从 <1% 到高达 20% 不等。 事实上，疾病的严重程度根据公认的临床危险因素（年龄和合并症）而存在显着差异。 这种临床变异的生物学基础尚不清楚，但可能与两种病毒的变异有关 以及主持人的回应。详细了解严重疾病的危险因素，包括遗传和 环境因素和宿主免疫反应的性质，对于免疫系统的发展至关重要 预后生物标志物和有效的治疗方法。为了满足这一迫切需要，我们建议帮助发展和 参与 IMPACC 针对住院 COVID-19 患者的多中心纵向临床研究，并 免疫表型参与者使用共享的免疫学方法，该方法将由以下人员设计和执行 加州大学旧金山分校和其他参与机构的核心实验室。我们的具体目标是 1) 开发 已知或推定的住院成人受试者的前瞻性观察方便队列 COVID-19, 2) 使用该队列来描述特定免疫学评估和 住院患者中 COVID-19 的临床病程，以及 3) 在 UCSF 建立三个核心实验室，以 支持这个多中心队列的免疫表型分析。这些核心实验室将进行批量RNA 外周血单核细胞 (PBMC) 测序，批量宏基因组下一代 对气管内抽吸样本进行测序 (mNGS) 和血清噬菌体展示测定 (PhIP-Seq)。 成功完成这些目标将产生有关病毒载量之间关系的关键信息， 宿主免疫反应和不良临床结果迫切需要生物标志物 的发展和合理的治疗目标。此外，本研究中储存的细胞样本可能 直接促进中和抗体和疫苗策略的开发，这将是我们的最终目标 防止这种非同寻常的流行病再次发生。快速而有力的科学和医疗反应 NIAID 和该联盟中的学术界提出的类型是 需要采取广泛的应对措施来保护所有人的健康和福祉、我们的医疗保健系统以及 维护全球健康和福利的更广泛的社会结构。
