Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection is associated with proinflammatory cytokine release as mediators of host antiviral response to the infection. Cytokine persistent elevation leads to post-Coronavirus disease-2019 (COVID-19) post-COVID-19 sequela (PCS) reported in about 60% of patients affecting individual's normal life after recovery. This study evaluates relationship of cytokines and chemokines pattern during and postinfection to PCS events. Serum samples collected from 82 individuals with symptomatic, asymptomatic, or no SARS-CoV-2 infection were classified as recently or formerly infected groups according to levels of anti-2019nCoV Immunoglobulin G/Immunoglobulin M. Levels of interleukin (IL)-1, IL-1, IL-6, IL-8, interferon alpha (IFN-), tumor necrosis factor alpha (TNF-), granulocyte macrophage colony-stimulating factor (GM-CSF), and monocyte chemoattractant protein-1 were assessed via ELISA for each individual. All asymptomatic groups showed nonsignificant differences in cytokines' levels than control group. Significant elevation of IFN-, TNF-, and GM-CSF levels were observed in recent symptomatic, while IFN- and TNF- levels were significant in former symptomatic groups. We observed an association between fever with IL-1 and IFN- levels, fatigue with TNF- and GM-CSF, dyspnea with IFN-, TNF-, and GM-CSF, and chest-wheezing with GM-CSF. Individuals were surveyed 12 months postsampling for PCS events. Among 35 responders to survey, 8 (22.8%) reported PCS events, 6 of which were females. Upon studying PCS events, IL-8, IFN-, TNF-, and GM-CSF levels showed significant elevation in active infection, that was not seen in a resolved state of infection. Cytokines patterns suggest that either a persistent elevation in levels or damage caused during infection contributes to PCS. Although with the limited sample size, our study emphasizes the importance to conduct medical approaches targeting the associated cytokines to improve the PCS symptoms.
严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 感染与促炎细胞因子的释放有关,这些细胞因子是宿主对感染的抗病毒反应的介质。细胞因子持续升高导致约 60%的患者出现新冠肺炎(COVID-19)后 COVID-19 后遗症(PCS),影响患者康复后的正常生活。本研究评估了感染期间和感染后细胞因子和趋化因子模式与 PCS 事件的关系。从 82 名有症状、无症状或无 SARS-CoV-2 感染的个体中采集血清样本,根据抗 2019nCoV 免疫球蛋白 G/免疫球蛋白 M 的水平将其分为近期或既往感染组。通过 ELISA 评估每个个体的白细胞介素 (IL)-1、IL-6、IL-8、干扰素 α (IFN-α)、肿瘤坏死因子 α (TNF-α)、粒细胞巨噬细胞集落刺激因子 (GM-CSF) 和单核细胞趋化蛋白-1 的水平。所有无症状组的细胞因子水平与对照组相比均无显著性差异。近期有症状组中观察到 IFN-α、TNF-α和 GM-CSF 水平显著升高,而既往有症状组中 IFN-α和 TNF-α水平显著升高。我们观察到发热与 IL-1 和 IFN-α水平、疲劳与 TNF-α和 GM-CSF 水平、呼吸困难与 IFN-α、TNF-α和 GM-CSF 水平、胸闷与 GM-CSF 水平之间存在关联。个体在采样后 12 个月接受 PCS 事件调查。在对调查做出回应的 35 名个体中,有 8 名(22.8%)报告了 PCS 事件,其中 6 名为女性。在研究 PCS 事件时,在活动性感染中观察到 IL-8、IFN-α、TNF-α和 GM-CSF 水平显著升高,而在感染的消退状态中则未观察到这些水平。细胞因子模式表明,无论是水平持续升高还是感染过程中造成的损伤,都可能导致 PCS。尽管样本量有限,但我们的研究强调了进行针对相关细胞因子的医疗干预以改善 PCS 症状的重要性。
