项目摘要

PROJECT SUMMARY/ABSTRACT: Rationale: The COVID-19 pandemic has affected over 42 million individuals in the United States and long-term complications are frequently reported, referred to as post-acute sequelae of SARS-CoV-2 (PASC). Even among survivors with mild acute illness, neurologic symptoms such as chronic fatigue, dysautonomia, and cognitive impairment are frequently reported. To date, the etiology and pathophysiology of neurologic PASC remain unclear; however, underlying autoantibodies and immune activation are suspected. In our prospective COVID-19 ID Persistence Cohort (C-PIC), more than half of COVID-19 survivors are reporting neurologic PASC at one year. We have identified an association between neurologic PASC with both SARS-CoV-2 specific antibodies and ANA. Specifically, nucleocapsid (NP) antibody levels are elevated compared to spike trimer (ST) antibody levels in participants with neurologic PASC. Furthermore, our preliminary data has identified a potential signal linking neurologic PASC and decreased gastrointestinal microbiota diversity. In this mentored career project, we hypothesize that autoimmunity, immune activation, and microbiome dysbiosis are associated with neurologic PASC. Candidate: As an Infectious Diseases physician with a master’s in public health and applied epidemiology and outbreak training through the Center for Disease Control and Prevention’s Epidemic Intelligence Service, I am uniquely positioned to study the epidemiology and determinants for neurologic PASC. My experience studying post- Ebola syndrome in Liberia provided me with the foresight to contribute viral persistence and sequelae aims to the C-PIC study, which includes longitudinal PASC survey data and biorepository specimens. Through the guidance of my outstanding multidisciplinary team of mentors, I plan to fulfill my training objectives of (1) developing expertise in advanced biostatistical analysis of survey data and (2) bridging translational research and descriptive cohort data. Environment: My team of mentors at Columbia University Irving Medical Center (CUIMC) are experts in epidemiology, biostatistics, immunology, and microbiome analysis. CUIMC also has a long track record of enabling young physician-scientists to develop independent and successful careers in academic medicine. Approach: We hypothesize that chronic fatigue, dysautonomia, and cognitive impairment sub-phenotypes of neurologic PASC have different underlying pathophysiology, including autoimmunity, immune activation, and microbiome dysbiosis. In Aim 1, we will characterize neurologic PASC epidemiology, trajectory, and sub-phenotypes using longitudinal neurologic PASC surveys. In Aim 2, we will identify associations between neurologic PASC with SARS-CoV-2 specific antibodies and autoantibodies. In Aim 3, we will identify associations between neurologic PASC and immune activation and explore the role of gut microbiota. This proposal provides an innovative approach to studying determinants for neurologic PASC, and the proposed training will facilitate my transition into an independently funded clinician-scientist.

项目摘要/摘要：理由：COVID-19 大流行已影响了超过 4200 万人在美国，长期并发症经常被报道，称为急性后并发症。 SARS-CoV-2 (PASC) 的后遗症即使在患有轻度急性疾病的幸存者中，也会出现神经系统症状，例如由于慢性疲劳、自主神经功能障碍和认知障碍的报道频繁，迄今为止，其病因和病因尚不清楚。神经系统 PASC 的病理生理学仍不清楚；然而，潜在的自身抗体和免疫在我们的前瞻性 COVID-19 ID 持久性队列 (C-PIC) 中，超过一半的人被怀疑被激活。 COVID-19 幸存者在一年后报告神经系统 PASC。我们发现两者之间存在关联。神经系统 PASC 具有 SARS-CoV-2 特异性抗体和 ANA，具体来说，是核衣壳 (NP)。与神经系统疾病中的尖峰三聚体 (ST) 抗体水平相比，抗体水平升高此外，我们的初步数据已经确定了连接神经系统 PASC 和 PASC 的潜在信号。在这个指导性职业项目中，我们认为胃肠道微生物群多样性下降。自身免疫、免疫激活和微生物群失调与神经系统 PASC 相关：作为一名拥有公共卫生和应用流行病学和疫情硕士学位的传染病医生通过疾病预防控制中心流行病情报服务的培训，我是独一无二的我的定位是研究神经系统 PASC 的流行病学和决定因素。利比里亚的埃博拉综合症为我提供了远见，有助于病毒的持久性和后遗症的目的 C-PIC 研究，包括纵向 PASC 调查数据和生物样本库样本。在我杰出的多学科导师团队的指导下，我计划实现我的培训目标（1）发展调查数据的高级生物统计分析方面的专业知识，以及（2）桥接转化研究和描述性队列数据：我在哥伦比亚大学欧文医学中心的导师团队。 (CUIMC) 是流行病学、生物统计学、免疫学和微生物组分析方面的专家。在帮助年轻医师科学家在以下领域发展独立和成功的职业生涯方面有着长期的记录学术医学方法：我们认为慢性疲劳、自主神经功能障碍和损伤。神经系统 PASC 的亚表型具有不同的潜在病理生理学，包括自身免疫、在目标 1 中，我们将描述神经 PASC 流行病学特征。在目标 2 中，我们将使用纵向神经学 PASC 调查来确定轨迹和亚表型。在目标 3 中，我们研究了神经 PASC 与 SARS-CoV-2 特异性抗体和自身抗体之间的关联。将确定神经 PASC 与免疫激活之间的关联，并探索肠道的作用该提案提供了一种研究神经 PASC 决定因素的创新方法，以及拟议的培训将有助于我转变为一名独立资助的临床医生科学家。
