概括
I型干扰素和自身抗体是COVID-19 ARDS的关键. 在CARDS患者中,德甲治疗降低了IL-6,而IL-8仍然很高,表明膜炎症发生了变化. 在CARDS患者中,IFN自身抗体升高.
科学领域:
- 肺部医学 肺部医学
- 免疫学 免疫学 免疫学
- 关键的护理关键的护理
背景情况:
- I型干扰素 (IFN-I) 和自身抗体对于控制SARS-CoV-2感染至关重要.
- 在COVID-19急性呼吸窘迫综合征 (CARDS) 中,这些媒介体的气膜水平未得到充分研究,并且在ARDS病因学中没有进行比较.
- 德克萨米他 (DXM) 对这些气囊介质的影响仍然未知.
研究的目的:
- 为了研究心脏病患者的膜-毛囊膜完整性,细胞因子概况和IFN自身抗体.
- 为了在不同的ARDS病因学中比较这些介质.
- 评估DXM处理对这些参数的影响.
主要方法:
- 评估表皮层内液 (ELF) 容量和蛋白质度,以评估膜-毛囊膜完整性.
- 测量膜和系统度的介质蛋白 (IL-6,IL-8) 和干扰素 (IFN-I,II,III).
- 来自CARDS患者,非CARDS患者和健康对照者的支气管洗液 (BALF) 和血中的量化IFN自身抗体.
主要成果:
- 卡德斯患者表现出ELF体积和蛋白质水平的增加,这表明屏障破坏.
- 膜IL-8水平在CARDS患者中高,不管他们接受了DXM治疗.
- 在CARDS患者中,DXM治疗与较低的全身和膜IL-6水平有关.
- 在CARDS和非CARDS患者之间,膜IFN水平相似.
- 在CARDS患者的BALF中,IFN自身抗体水平升高,独立于DXM,但在血中与对照者相似.
结论:
- 卡德斯患者表现出显著的膜-毛细血管屏障破坏与隔离IL-8.
- 德甲治疗可调节CARDS中的IL-6水平,但不能调节IL-8或IFN自身抗体.
- 在CARDS患者的BALF中IFN-I自身抗体的升高表明局部免疫失调可能独立于DXM.
