长期COVID仍然非常普遍,即使在24个月后,呼吸道和神经系统症状也很常见. 德尔塔变种显著增加了神经长期COVID的风险,而疫苗接种可能会提供保护.
科学领域:
- 传染性疾病 传染性疾病
- 公共卫生 公共卫生
- 神经学 神经学
背景情况:
- 长期COVID是一个重要的全球健康问题,具有多种表现.
- 有限的数据存在于长时间的特定长期COVID症状的预测因子.
- 了解这些预测因素对于公共卫生战略至关重要.
研究的目的:
- 调查长期COVID发病率和临床表现的预测因素.
- 评估病毒变异在长期COVID发展中的作用.
- 确定影响长期COVID后状况的因素.
主要方法:
- 来自意大利两个中心的住院COVID-19患者 (年龄大于18岁) 被录取 (2020年3月至2022年4月).
- 通过电话问卷来评估长期COVID的发病率和呈现情况.
- 后勤回归分析了风险因素,报告赔率比率 (ORs) 和95%置信区间 (CI).
主要成果:
- 在中位数19个月的随访期间,长期COVID的累积发病率为91.7%.
- 最常见的症状涉及呼吸系统 (80.5%) 和神经系统 (77.3%).
- 德尔塔变种感染强烈预测神经精神症状 (OR:9.61);疫苗接种降低了整体长期COVID几率 (OR:0.34).
结论:
- 长期COVID症状持续存在,感染后18-24个月的高患病率.
- 感染Delta变种与增加COVID后神经系统疾病的风险有关.
- 接种疫苗可以减轻长期COVID症状的风险.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
