TITLE: The role of lipids in obesity-mediated protection in sepsis ABSTRACT Sepsis is an important clinical problem for which no specific therapies are currently available. Clinical studies indicate that obesity is paradoxically associated with improved survival in sepsis; however, as obesity is a risk factor for a wide variety of pathologies, it cannot be recommended as an option to protect against sepsis. It is, therefore, important to understand the underlying mechanisms that lead to obesity-mediated protection in sepsis as a step towards the development of novel therapeutic approaches. In this study, we will utilize existing clinical data and biospecimens derived from sepsis patients to explore a connection between metabolic adaptation and obesity-mediated protection in sepsis. In Specific Aim 1, we will evaluate the association between obesity status and plasma lipid levels during sepsis using existing clinical data and plasma samples from the ARDSNet-SAILS clinical trial. In Specific Aim 2, we will determine whether plasma lipid levels influence sepsis outcomes by first correlating plasma lipid levels with major sepsis outcomes such as mortality, length of hospital stay, organ dysfunction, and related biological/physiological variables. Additionally, we will investigate whether the protective effect of obesity in improving sepsis survival is abolished with the lipid-lowering drug rosuvastatin. The long-term goal of this work is to identify parameters related to obesity-mediated protection in sepsis, which can be further mechanistically investigated and lead to the development of potential therapeutic interventions for sepsis.

标题：脂质在肥胖介导的脓毒症保护中的作用 抽象的 脓毒症是一个重要的临床问题，目前尚无特定的治疗方法。临床研究 表明肥胖与脓毒症患者生存率的提高存在矛盾关系；然而，由于肥胖是一种风险 由于它是多种病理的一个因素，因此不推荐将其作为预防败血症的选择。这是， 因此，了解导致肥胖介导的脓毒症保护作用的潜在机制非常重要 作为开发新治疗方法的一步。在本研究中，我们将利用现有的临床 来自脓毒症患者的数据和生物样本，探索代谢适应和 肥胖介导的脓毒症保护作用。在具体目标 1 中，我们将评估肥胖状况之间的关联 使用来自 ARDSNet-SAILS 的现有临床数据和血浆样本来评估脓毒症期间的血浆脂质水平 临床试验。在具体目标 2 中，我们将首先确定血浆脂质水平是否影响败血症结果 将血浆脂质水平与主要脓毒症结局（例如死亡率、住院时间、器官）相关联 功能障碍以及相关的生物/生理变量。此外，我们将调查是否有保护措施 降脂药物瑞舒伐他汀消除了肥胖对改善脓毒症生存率的影响。长期来看 这项工作的目标是确定与脓毒症中肥胖介导的保护相关的参数，这可以进一步 从机制上进行研究并导致脓毒症潜在治疗干预措施的开发。
