脓毒症幸存者持续炎症与更高的死亡率相关联
根据Pittsburgh学院的医师科学家领导的一项研究,在出院后,在其住院住院的四个败血症患者中患者患者患者的患者的炎症水平升高了炎症率升高了医学与退伍军人事务匹兹堡医疗保健系统。
结果,今天发布Jama Network开放,向未来治疗的情况达到诱人的线索,这可能改善败血症幸存者的结果。
据世界卫生组织称,败血症是一种危及生命的病情,当机构对身体对感染的反应造成自己的组织和器官,并影响全世界超过3000万人。
"Sepsis is the leading cause of death among hospitalized patients. Patients discharged from the hospital aren't out of the woods yet. Approximately 1 out of every 3 sepsis survivors will die in the following year," said lead author Sachin Yende, M.D., M.S., professor of critical care medicine and clinical and translational science at Pitt's School of Medicine, and vice president of critical care and deputy chief of staff at the Veterans Affairs Pittsburgh Healthcare System. "Our new findings about慢性炎症出院后表明解决这种条件可能是改善患者的长期结果的重要意义。“
几乎所有脓毒症患者都有增加炎在他们住院的前几天的血液中。这种炎症是否解决或持续存在很差。Yende和他的团队随访了483人,于2012年和2017年之间的12名美国医院12名与败血症住院,并幸存下来。详细信息收集在研究参与者上,他们通过电话和家访联系,入住健康访谈和A次入学后六个月和12个月。血液样本。
大约四分之一的参与者表现出持续升高的炎症水平,一半显示出院后的免疫抑制生物标志物水平高达一年。这些患者的再入院率较高 - 与炎症和免疫抑制生物标志物在住院后恢复正常的同龄人相比,患有心脏病和中风和死亡。
"The participants with increased inflammation had levels that were twice as high as levels in healthy individuals and that elevated inflammation persisted long after hospital discharge," said senior author Derek Angus, M.D., M.P.H., professor and chair of Pitt's Department of Critical Care Medicine and director of Pitt's Clinical Research, Investigation, and Systems Modeling of Acute Illness (CRISMA) Center. "Sepsis increases risk of心脏病和中风,我们首次将这些不利结果与持续炎症联系起来。这将在未来的研究中打开大门,为什么在医院排放后至少一年的炎症和旨在改变炎症的治疗的发展,旨在改善健康。“
研究人员警告说,在败血症诊断之前,他们没有对研究参与者进行血液测试。在住院前,它们可能有可能导致发展的升高败血症在住院后继续持续存在。
