概括
在COVID-19 (PASC) 的急性后果中,疲劳是常见的,无论最初的疾病严重程度如何. 血液T细胞数量,特别是CD4+T细胞,与疲劳严重程度相关,这表明这种常见的长期COVID症状的潜在生物标志物.
科学领域:
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 公共卫生 公共卫生
背景情况:
- COVID-19 (PASC) 后急性后续影响大约10%的患者,呈现出各种症状,疲劳最为普遍.
- 对于可访问的血液生物标志物来评估PASC严重性的存在重大未满足的需求.
- 了解PASC的免疫基础对于开发有针对性的干预措施至关重要.
研究的目的:
- 调查免疫表型与PASC严重程度之间的相关性.
- 探索PASC的潜在血液生物标志物,特别是疲劳,一个常见的后续.
- 分析与初始COVID-19严重程度和长期疲劳相关的免疫反应.
主要方法:
- 一项针对176名免疫性COVID-19康复者进行的前性队列研究,根据最初的疾病严重程度分层.
- 临床,心理和免疫表型测定在症状出现后大约10周进行.
- 评估COVID-19相关的疲劳动力学和与临床和免疫标记物的相关性.
主要成果:
- 在所有最初的COVID-19严重程度组和PASC演示中经常报告疲劳.
- 中和抗体标位与严重急性疾病相关,但不是PASC.
- 在PASC患者中,外围CD4+T细胞计数与疲劳严重程度有独立的相关性.
结论:
- 无论COVID-19最初的严重程度如何,PASC风险都是相似的.
- 疲劳严重程度与CD4+T细胞计数之间的相关性表明它们在PASC病变发生过程中的作用.
- CD4+ T 细胞计数可能作为后COVID-19疲劳的潜在血液生物标志物.

Myocarditis II: Clinical Features and Diagnostic Tests
12
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Muscle Recovery and Fatigue
2.1K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
