Natural killer (NK) cells are among the most important innate immunity members, which are the first cells that fight against infected cells. The function of these cells is impaired in patients with COVID-19 and they are not able to prevent the spread of the disease or destroy the infected cells. Few studies have evaluated the effects of COVID-19 vaccines on NK cells, though it has been demonstrated that DNA vaccines and BNT162b2 can affect NK cell response. In the present paper, the effects of SARS-CoV-2 on the NK cells during infection, the effect of vaccination on NK cells, and the NK cell-based therapies were reviewed.
自然杀伤细胞(NK)是最重要的先天免疫成员之一,是第一个对抗感染细胞的细胞。在COVID-19患者中,这些细胞的功能受损,它们无法阻止疾病的传播或破坏受感染的细胞。很少有研究评估COVID-19疫苗对NK细胞的影响,尽管已经证明DNA疫苗和BNT162b2可以影响NK细胞的反应。本文就SARS-CoV-2在感染过程中对NK细胞的影响、疫苗接种对NK细胞的影响以及NK细胞为基础的治疗方法进行综述。

This is a summary of an article about part of a clinical study for the BNT162b2 COVID-19 vaccine, also called the Pfizer-BioNTech vaccine. The article was published in the New England Journal of Medicine in May 2021. This summary describes how the vaccine worked in participants 12- to 15-years old. The part of the study described in the article is ongoing and expected to finish March 2023. This means that the final results may be different from the results included in this summary. The part of the study described in this summary included participants 12- to 15-years old who had no serious health issues. The BNT162b2 vaccine had already been studied in participants 16 years of age or older. In this part of the study, the researchers wanted to find out: How effective and safe the vaccine was in participants 12- to 15-years old. What the immune response to the vaccine and the vaccine safety were like in 12- to 15-year-olds compared with 16- to 25-year-olds. How well the vaccine prevented SARS-CoV-2 infections in participants who received the vaccine compared to those who did not. This is also called efficacy of the BNT162b2 vaccine Half of the participants in this study received 2 injections of the BNT162b2 vaccine and half received 2 injections of a placebo in a muscle of the upper arm. The placebo looked like the BNT162b2 vaccine but did not have any active vaccine in it. BNT162b2 had a favorable safety profile. The most common reactions were pain at the injection site, fatigue, and headache. None of the participants had serious reactions to the vaccine. The 12- to 15-year-old participants' immune system responses to the BNT162b2 vaccine were as good as or stronger than the 16- to 25-year-old participants' immune responses. The participants who received the BNT162b2 vaccine were less likely to get COVID-19 compared with the participants who got the placebo. Clinical Trial Registration: NCT04368728 ( ClinicalTrials.gov )
这是一篇关于BNT162b2新冠肺炎疫苗(也称为Pfizer-BioNTech疫苗)临床研究部分内容的文章摘要。这篇文章于2021年5月发表在《新英格兰医学杂志》上。该摘要描述了疫苗如何在12至15岁的参与者中发挥作用。文章中描述的这部分研究正在进行中,预计将于2023年3月结束。这意味着最终结果可能与本摘要中包含的结果不同。本摘要中描述的研究部分包括12至15岁的参与者,他们没有严重的健康问题。BNT162b2疫苗已经在16岁或以上的参与者中进行了研究。在这部分研究中,研究人员想弄清楚:疫苗在12至15岁的参与者中的有效性和安全性。与16至25岁的人相比,12至15岁的人对疫苗的免疫反应和疫苗的安全性是什么样的。与未接种疫苗的参与者相比,疫苗预防严重急性呼吸系统综合征冠状病毒2型感染的效果如何。这也被称为BNT162b2疫苗的疗效本研究的一半参与者在上臂肌肉中注射了2针BNT162b2疫苗,一半参与者注射了2剂安慰剂。安慰剂看起来像BNT162b2疫苗,但其中没有任何活性疫苗。BNT162b2具有良好的安全性。最常见的反应是注射部位疼痛、疲劳和头痛。没有一名参与者对疫苗有严重反应。12至15岁参与者对BNT162b2疫苗的免疫系统反应与16至25岁参与者的免疫反应一样好或更强。与接种安慰剂的参与者相比,接种BNT162b2疫苗的参与者感染新冠肺炎的可能性较小。临床试验注册:NCT04368728(ClinicalTrials.gov)

Aim: To evaluate the significance of E gene analysis in addition to N and RdRp genes of SARS-CoV-2, and to compare the specificity and sensitivity of targets. Materials & methods: We used two reverse transcription-PCR assays: one targeting N, E and RdRp and the other targeting N and RdRp genes and analyzed variation in threshold cycle (Ct) values. Results: Of the 155 samples, 70.32% tested positive: all three genes were detected in 45.87%, N and RdRp in 19.27% and only N in 34.86%. Patients negative for the E gene were tested after symptoms disappeared and Ct values were significantly higher. Conclusion: Samples negative for the E gene were potentially false positive and clinical conditions should be assessed while interpreting results.
目的:评价除N和RdRp基因外的E基因分析对严重急性呼吸系统综合征冠状病毒2型的意义,并比较靶点的特异性和敏感性。材料与方法:我们使用了两种逆转录PCR检测:一种针对N、E和RdRp基因,另一种则针对N和RdRp基因,并分析了阈值周期(Ct)值的变化。结果:在155份样本中,70.32%的样本检测呈阳性:三种基因均检测出45.87%,N和RdRp检测出19.27%,仅N检测出34.86%。结论:E基因阴性的样本可能是假阳性,在解释结果时应评估临床情况。

Aim: We aimed to investigate the associated risk factors of deep vein thrombosis (DVT) among COVID-19 patients. Materials & methods: In this cross-sectional study the demographical data and clinical characteristics of 382 COVID-19 patients were collected and analyzed. Results: The DVT was observed in 53 patients (14.1%). The rate of death was significantly associated with the incidence of DVT, 48.1 versus 32.2% in non-DVT cases; p = 0.034). Also, BMI (p = 0.0001), renal failure (p = 0.001), lower-limb edema (p = 0.0001) and intubation (p = 0.004) were associated with the risk of DVT. Conclusion: COVID-19 patients with a higher BMI, renal failure, lower-limb edema and need for intubation were at a higher risk of DVT.

HLA and red blood cell antigen genotyping in SARS-CoV-2 convalescent plasma donors. 对 SARS-CoV-2 康复期血浆捐献者进行 HLA 和红细胞抗原基因分型。
IF 2.1 4区 医学 Q3 VIROLOGY Pub Date : 2023-01-01 Epub Date: 2023-02-20 DOI: 10.2217/fvl-2022-0058

Aim: More data is required regarding the association between HLA allele and red blood cell (RBC) antigen expression in regard to SARS-CoV-2 infection and COVID-19 susceptibility. Methods: ABO, RhD, 37 other RBC antigens and HLA-A, B, C, DRB1, DQB1 and DPB1 were determined using high throughput platforms in 90 Caucasian convalescent plasma donors. Results: The AB group was significantly increased (1.5×, p = 0.018) and some HLA alleles were found to be significantly overrepresented (HLA-B*44:02, C*05:01, DPB1*04:01, DRB1*04:01 and DRB1*07:01) or underrepresented (A*01:01, B51:01 and DPB1*04:02) in convalescent individuals compared with the local bone marrow registry population. Conclusion: Our study of infection-susceptible but non-hospitalized Caucasian COVID-19 patients contributes to the global understanding of host genetic factors associated with SARS-CoV-2 infection and severity.

目的:需要更多关于 HLA 等位基因和红细胞(RBC)抗原表达与 SARS-CoV-2 感染和 COVID-19 易感性之间关系的数据。方法:使用高通量平台测定 90 名高加索康复血浆供体的 ABO、RhD、37 种其他红细胞抗原和 HLA-A、B、C、DRB1、DQB1 和 DPB1。结果发现与当地骨髓登记人群相比,AB 组明显增加(1.5 倍,p = 0.018),并且发现某些 HLA 等位基因在康复者中的比例明显偏高(HLA-B*44:02、C*05:01、DPB1*04:01、DRB1*04:01 和 DRB1*07:01)或偏低(A*01:01、B51:01 和 DPB1*04:02)。结论我们对易感染但未住院的高加索 COVID-19 患者的研究有助于全球了解与 SARS-CoV-2 感染和严重程度相关的宿主遗传因素。

In late 2019, SARS-CoV-2 was detected in China and spread worldwide. In rare cases, children who were infected with COVID-19 may develop multisystem inflammatory syndrome (MIS-C), which could have higher mortality than COVID-19 itself. Therefore, diagnosis and management are critical for treatment. Specifically, most of the initial treatment options of MIS-C choose intravenous immunoglobulin (IVIG) and steroids as the first-line treatment for patients. Moreover, antagonists of some cytokines are used as potential future therapeutics. Of note, therapeutic plasmapheresis can be used as a treatment for refractory severe MIS-C. We believe that each patient, especially those with comorbid conditions, should have individualized treatment based on both multidisciplinary consensus approach and expert opinion.

2019年底,SARS-CoV-2在中国被发现并传播到世界各地。在极少数情况下,感染COVID-19的儿童可能会出现多系统炎症综合征(MIS-C),其死亡率可能高于COVID-19本身。因此,诊断和管理对治疗至关重要。具体而言,大多数MIS-C的初始治疗方案选择静脉注射免疫球蛋白(IVIG)和类固醇作为患者的一线治疗。此外,一些细胞因子的拮抗剂被用作潜在的未来治疗药物。值得注意的是,治疗性血浆置换可用于治疗难治性重度misc。我们认为,每个患者,特别是那些有合并症的患者,应该在多学科共识方法和专家意见的基础上进行个体化治疗。

Aim: The aim of this study was to investigate the activity of NLRP3 inflammasome and its effect on inducing severe pneumonia 1 week after influenza A virus (IAV) infection. Materials & methods: The expression levels of NLRP3, caspase-1 and IL-1β were assessed in murine macrophages stimulated with IAV. And the severity of viral pneumonia in mice was explored. Results & conclusion: The data showed that although the expression of NLRP3 diverged, activity of NLRP3 inflammasome was enhanced 1 week after IAV infection, and more severe viral pneumonia was associated with IL-1β in serum. It infers that enhanced activity of NLRP3 inflammasome induces augmented expression of IL-1β and severe pneumonia in a NLRP3-independent way, 1 week after IAV infection.
目的:研究NLRP3炎症小体的活性及其在甲型流感病毒(IAV)感染后1周诱导重症肺炎中的作用。材料与方法:检测IAV刺激的小鼠巨噬细胞中NLRP3、胱天蛋白酶-1和IL-1β的表达水平。并对小鼠病毒性肺炎的严重程度进行了探讨。结果与结论:尽管NLRP3的表达存在差异,但在感染IAV后1周,NLRP3炎症小体的活性增强,更严重的病毒性肺炎与血清中的IL-1β有关。由此推断,在IAV感染后1周,NLRP3炎症小体活性的增强以非NLRP3依赖的方式诱导IL-1β的表达增强和严重肺炎。
