Introduction. Timely prescribing of proactive cytokine storm therapy in patients with COVID-19 using targeted therapy is an important component of success in the treatment of this disease. However, the blockade of receptors to proinflammatory cytokines, in particular to IL-6, leads to shifts in immunoregulatory processes, the nature of which can determine the effectiveness of the therapy and the course of the postCOVID period of rehabilitation of the patient. The aim of the study - to study the dynamics of the parameters of innate and adaptive immunity in a patient with COVID-19 using an IL-6 receptor anatagonist. Material and methods. 30 hospitalized patients were examined with the diagnosis: COVID-19 coronavirus infection (confirmed), moderate form;complication: bilateral polysegmental pneumonia. The comparison group consisted of practically healthy donors (30 people). The dynamics of laboratory parameters (general clinical, biochemical and immunological) were evaluated against the background of therapy with IL-6 blockers. Results. The presence of lymphopenia in the patient, an increase in the level of CRP, LTK, fibrinogen, lactate, IL-6 require the use of proactive anti-cytokine therapy. The timely administration of these drugs (in particular, the IL-6 receptor inhibitor) has a positive effect on the course of the disease and the recovery of patients. In the immune system, after the introduction of monoclonal antibodies to IL-6 receptors, 2 weeks after administration, there is an increase in the maturation of T-lymphocytes, documented by an increase in the content of T-lymphocytes with helper function with a simultaneous decrease in the number of natural killers, B-lymphocytes and disimmunoglobulinemia of IgA, IgM and IgG classes. Conclusion. The use of monoclonal antibodies to IL-6 receptors in patients with a moderate form of COVID-19 leads to dysregulatory processes in the immune system with their gradual normalization by 2 weeks after administration.
介绍。及时给予靶向治疗的COVID-19患者积极的细胞因子风暴治疗是成功治疗该疾病的重要组成部分。然而,受体对促炎细胞因子的阻断,特别是对IL-6的阻断,会导致免疫调节过程的改变,其性质可以决定治疗的有效性和患者在covid后康复期间的进程。本研究的目的是利用IL-6受体拮抗剂研究COVID-19患者先天免疫和适应性免疫参数的动态变化。材料和方法。对30例住院患者进行检查,诊断:新型冠状病毒感染(确诊),中度;并发症:双侧多节段性肺炎。对照组由实际健康的捐赠者(30人)组成。在使用IL-6阻滞剂治疗的背景下,对实验室参数(一般临床、生化和免疫学)的动态进行评估。结果。患者存在淋巴细胞减少,CRP、LTK、纤维蛋白原、乳酸、IL-6水平升高,需要采用主动抗细胞因子治疗。及时给予这些药物(特别是IL-6受体抑制剂)对疾病的病程和患者的康复有积极的作用。在免疫系统中,在引入针对IL-6受体的单克隆抗体后,给药2周后,t淋巴细胞的成熟程度增加,具有辅助功能的t淋巴细胞含量增加,同时自然杀手、b淋巴细胞和IgA、IgM和IgG类非免疫球蛋白血症的数量减少。结论。在中度COVID-19患者中使用针对IL-6受体的单克隆抗体会导致免疫系统的失调过程,并在给药后2周逐渐正常化。

SARS-CoV-2 is the cause of COVID-19, which has a serious effect on the lower respiratory system. COVID-19 causes bilateral pneumonia and acute respiratory syndrome. Smell disorders are important diagnostic symptoms of COVID-19. This symptom is detected in about 90 % of cases. Anosmia may be the first or even the only symptom and may appear before other symptoms of SARS-CoV-2 infection. In the context of the COVID-19 epidemic, anosmia can be considered a clinical diagnostic criterion when laboratory tests are not available. The sense of smell is one of the most important senses needed to gain information about the environment. Anosmia can occur in both COVID-19 and allergic rhinitis (AR), which can make it difficult to detect the origin of these symptoms and make a diagnosis in the context of the COVID-19 pandemic. Research results indicate AR is not an aggravating factor for COVID-19. Comorbidity of AR does not affect the reduction of the sense of smell in patients with COVID-19. Patients with AR are recommended to use antihistamines and intranasal corticosteroids for relief of symptoms. Control of AR symptoms can help prevent the spread of SARS-CoV-2 infection. It can be assumed that both local and oral corticosteroids at COVID-19 can be regarded as effective in the treatment of olfactory dysfunction. To restore the sense of smell in patients with AR and COVID-19, experts recommend regular olfactory training, which, at the moment, is the only modern scientifically based therapy for restoring post-viral loss of smell. The use of face masks and respirators during a pandemic aims to minimize exposure to allergens and the SARS-CoV-2 virus. However, prolonged wearing of masks and respirators makes breathing even more difficult with rhinitis caused by AR or COVID-19, which reduces the quality of life and worsens the clinical picture.
SARS-CoV-2是COVID-19的病因,对下呼吸系统有严重影响。COVID-19可引起双侧肺炎和急性呼吸综合征。嗅觉障碍是COVID-19的重要诊断症状。在大约90%的病例中检测到这种症状。嗅觉缺失可能是SARS-CoV-2感染的第一个症状,甚至是唯一的症状,可能出现在其他症状之前。在2019冠状病毒病流行的背景下,嗅觉缺失可被视为无法获得实验室检测的临床诊断标准。嗅觉是获取环境信息所需的最重要的感官之一。嗅觉缺失在COVID-19和过敏性鼻炎(AR)中都可能发生,这使得在COVID-19大流行的背景下难以发现这些症状的起源并做出诊断。研究结果表明,AR不是新冠肺炎的加重因素。AR的合并症不影响COVID-19患者嗅觉的下降。AR患者建议使用抗组胺药和鼻内皮质类固醇来缓解症状。控制AR症状有助于防止SARS-CoV-2感染的传播。可以认为,在COVID-19中,局部和口服皮质类固醇均可视为治疗嗅觉功能障碍的有效方法。为了恢复AR和COVID-19患者的嗅觉,专家建议定期进行嗅觉训练,这是目前唯一一种恢复病毒后嗅觉丧失的现代科学疗法。在大流行期间使用口罩和呼吸器的目的是尽量减少接触过敏原和SARS-CoV-2病毒。然而,长期佩戴口罩和呼吸器会使因AR或COVID-19引起的鼻炎患者呼吸更加困难,从而降低生活质量并使临床情况恶化。

Introduction. The determination of antibodies against the Spike (S) protein of the novel coronavirus is widely used to confirm current or past infection with SARS-CoV-2, and as an indicator of the effectiveness of vaccination against COVID-19. The most common method for detecting anti-S-antibodies is enzyme-linked immunosorbent assay (ELISA), which uses a recombinant S-protein. Immunofluorescence followed by flow cytometry provides an alternative approach to detect anti-S-antibodies, where a protein in the native transmembrane conformation is used as the S-antigen. The aim of the study was to develop a method for determining anti-S-antibodies using flow cytometry, and to select the most appropriate method for processing experimental data. Material and methods. The study involved 22 volunteers (7 men and 15 women aged 25 to 70 years, median 48). All volunteers were vaccinated with two doses of the <> vaccine between January and February 2021. Donor sera samples were collected before vaccination with <> and 3 months after vaccination. 5 volunteers had already had a mild form of COVID-19 before the time of vaccination. The remaining 17 volunteers did not encounter the SARS-CoV-2. Antibodies against S-protein were determined by immunofluorescence with registration on a flow cytometer. HEK293 cells were transiently transfected with a plasmid encoding the wild type S-protein which was used as target. Transfection was performed by the calcium phosphate method. Cells were incubated with serially diluted sera and then stained with anti-IgG-PE and anti-IgM-FITC secondary antibodies. The fluorescence level was measured using a flow cytometer. As a measurement result, the mean fluorescence intensity (MFI) obtained at 1:18 serum dilution, or the area under the titration curve (area under curve, AUC) was used. Anti-RBD-antibodies were determined using enzyme immunoassay, and virus-neutralizing activity using pseudotyped or surrogate virus-neutralization analysis (pVNA and sVNA). Results. Using the developed method, the formation of anti-S antibodies of the IgG and IgM isotypes was shown 3 months after immunization with the <> vaccine. In a simplified version of the method, the relative concentration of antibodies was determined at a single dilution of the test serum by measuring the mean fluorescence intensity (MFI) of the target cells. More reliable results were obtained by construction the titration curve and calculating the area under the curve (AUC). The results thus obtained correlated well with the detection of anti-RBD antibodies by ELISA, as well as with virus neutralization data in pseudotyped and surrogate assays. Conclusion. Flow cytometry is a convenient method for the simultaneous determination of anti-S antibodies of IgG and IgM isotypes in human serum. The advantages of the method include the fact that the S-protein is presented in a native transmembrane conformation. After minor modification, the established met
介绍。新型冠状病毒Spike (S)蛋白抗体的检测被广泛用于确认当前或过去的SARS-CoV-2感染,并作为COVID-19疫苗接种有效性的指标。检测抗s抗体最常用的方法是酶联免疫吸附试验(ELISA),它使用重组s蛋白。免疫荧光随后流式细胞术提供了一种检测抗s抗体的替代方法,其中天然跨膜构象的蛋白质用作s抗原。本研究的目的是建立一种利用流式细胞术检测抗s抗体的方法,并选择最合适的方法处理实验数据。材料和方法。该研究涉及22名志愿者(7名男性和15名女性,年龄在25至70岁之间,中位数为48岁)。所有志愿者都在2021年1月至2月期间接种了两剂>疫苗。接种>前和接种后3个月采集供体血清样本。5名志愿者在接种疫苗前已经患有轻度COVID-19。其余17名志愿者没有遇到SARS-CoV-2。在流式细胞仪上用免疫荧光标记法检测s蛋白抗体。用编码野生型s蛋白的质粒瞬时转染HEK293细胞作为靶细胞。采用磷酸钙法转染。细胞用连续稀释的血清孵育,然后用抗igg - pe和抗igm - fitc二抗染色。用流式细胞仪测定荧光水平。测量结果采用1:18血清稀释时的平均荧光强度(MFI),或滴定曲线下面积(area under curve, AUC)。采用酶免疫法检测抗rbd抗体,采用假型或替代病毒中和分析(pVNA和sVNA)检测病毒中和活性。结果。使用该方法,>疫苗免疫3个月后,IgG和IgM同型抗s抗体的形成。在该方法的简化版本中,通过测量靶细胞的平均荧光强度(MFI),在测试血清的一次稀释下确定抗体的相对浓度。通过构建滴定曲线并计算曲线下面积(AUC),得到了较为可靠的结果。由此获得的结果与ELISA检测抗rbd抗体以及假型和替代试验的病毒中和数据具有良好的相关性。结论。流式细胞术是同时测定人血清中IgG和IgM同型抗s抗体的简便方法。该方法的优点包括s蛋白以天然的跨膜构象呈现。建立的方法经过少量修改后,可用于检测SARS-CoV-2突变体的抗s抗体水平。版权所有©2022新浪传媒出版社。版权所有。
