Introduction. Extracorporeal membrane oxygenation has found wide application in clinical practice during the COVID-19 pandemic. Oxidative stress, endothelial dysfunction, and systemic inflammatory response syndrome play an important role in the pathogenesis of COVID-19. Our research was designed to study correlations in-between those factors and the impact of extracorporeal membrane oxygenation on them.Aim. The study of systemic inflammatory response and endothelial function in patients with COVID-19 during extracorporeal membrane oxygenation.Material and methods. In the course of a prospective study, we examined 100 COVID-19 patients aged 26 to 75 years, median 55 years [47;60], who were treated at the N.V. Sklifosovsky Research Institute for Emergency Medicine, using extracorporeal membrane oxygenation. As a control group (normal), 25 practically healthy people whose median age was 32 years [25;39] were examined. The function of the vascular endothelium was assessed by the content of nitric oxide stable metabolites in the blood serum and the level of angiotensin-converting enzyme. Next, the ratio of nitric oxide metabolite to angiotensin-converting enzyme level was calculated, reflecting the imbalance between endotheliumdependent vasodilation and vasoconstriction. To assess the severity of oxidative stress in blood serum, malondialdehyde was determined as a marker of lipid peroxidation. The state of the antioxidant system was assessed in terms of total antioxidant status of blood serum. The presence of an imbalance in the system of lipid peroxidation and the antioxidant system total antioxidant status was judged by the oxidative stress coefficient, i.e. the ratio of malondialdehyde to the total antioxidant activity.Results. The analysis showed the presence and progression of endothelial dysfunction, impaired vascular regulation, activation of free radical processes, the presence of an imbalance in the prooxidant/antioxidant system, as well as the progression of the inflammatory process with a decrease in the level of markers of the COVID-19 severity.Conclusion. Further studies of the correlation between endothelial damage and the severity of the systemic inflammatory response syndrome may be of fundamental importance for explaining the pathophysiological mechanisms of COVID-19 course and developing new treatments for such patients.
介绍。在新冠肺炎大流行期间,体外膜氧合在临床实践中得到了广泛应用。氧化应激、内皮功能障碍和全身炎症反应综合征在COVID-19的发病机制中起重要作用。我们的研究旨在探讨这些因素之间的相关性以及体外膜氧合对它们的影响。体外膜氧合对COVID-19患者全身炎症反应和内皮功能的影响。材料和方法。在一项前瞻性研究中,我们检查了100例年龄在26至75岁之间的COVID-19患者,中位年龄为55岁[47;60],他们在N.V. Sklifosovsky急诊医学研究所接受体外膜氧合治疗。选取年龄中位数为32岁的实际健康人群25例作为对照组(正常)[25;39]。采用血清一氧化氮稳定代谢物含量和血管紧张素转换酶水平评价血管内皮功能。接下来,计算一氧化氮代谢物与血管紧张素转换酶水平的比值,反映内皮依赖性血管舒张和血管收缩之间的不平衡。为了评估血清中氧化应激的严重程度,丙二醛被确定为脂质过氧化的标志物。以血清总抗氧化状态评价抗氧化系统状态。通过氧化应激系数,即丙二醛与总抗氧化活性的比值来判断脂质过氧化系统和抗氧化系统中是否存在失衡。分析显示,内皮功能障碍、血管调节功能受损、自由基过程激活、促氧化/抗氧化系统失衡,以及炎症过程的进展,并伴有COVID-19严重程度标志物水平的下降。进一步研究内皮损伤与全身炎症反应综合征严重程度的相关性,可能对解释COVID-19病程的病理生理机制和开发新的治疗方法具有重要意义。

Background. Paracetamol poisoning is common all over the world, including in Russia. In 20–25% of cases, a massive dose of the drug is observed: more than 30–40 g of paracetamol at a time.The aim of the study was to demonstrate the efficacy of using an increased doses of acetylcysteine in the treatment of a massive paracetamol admission.Results. Patient G., 22 years old, took 70 tablets (35 g) of paracetamol for suicide 3 hours before admission to the hospital. The blood level of paracetamol 4 hours after taking it was 694.94 µg/mL. Upon admission to the hospital, acetylcysteine administering was started according to a 12-hour scheme. Subsequently, the administration of acetylcysteine was continued according to a 20-hour regimen with an increased dosage at the 2nd stage. Laboratory parameters, including aspartate aminotransferase and alanine aminotransferase, remained within the reference values during hospital stay. Conclusion. The case report we have presented shows the efficacy and expediency of using an increased doses of acetylcysteine in case of massive admission of paracetamol, which contributes to the prevention of the development of severe complications and a favorable course and outcome of the disease.

Background. The recurrence of autoimmune liver diseases can lead to reduced survival of recipients and grafts.Aim. To study the incidence and impact of the recurrence of autoimmune liver diseases on graft survival; the effect of maintenance immunosuppression on the recurrence of autoimmune diseases in liver transplant recipientsMaterial and methods. Transplantation outcomes in 111 recipients (21 recipients operated on for autoimmune hepatitis, 50 recipients operated on for primary biliary cirrhosis, and 40 recipients operated on for primary sclerosing cholangitis) were analyzed retrospectively.Results. The recurrence of autoimmune hepatitis is observed in 5%, the recurrence of primary biliary cirrhosis is in 10%, and the recurrence of primary sclerosing cholangitis is in 17% of cases. Among patients with recurrence of autoimmune diseases, men accounted for 54%, while for only 31% in the subgroup of patients without relapse (p=0.004). The followup for recipients with relapse (64.5 (42.8;82.0) months) was comparable to the follow-up for recipients without relapse (46.5 (17.9;103.5) months, p=0.54). A ten-year graft survival was significantly higher in the group of recipients with recurrent autoimmune diseases compared with recipients without autoimmune diseases recurrence (p<0.0001).Conclusions. The recurrence of autoimmune diseases leads to a decrease in graft survival. The effect of immunosuppression components on the risk of recurrence of autoimmune diseases in the graft has not been established.

Introduction. The search for methods to reduce the time of treatment of burns and wounds of the donor sites currently remains relevant.Aim. Objective of this retrospective study was to evaluate the effectiveness of local treatment of II–IIIA degree burns and donor site wounds with dressings based on allogeneic type I collagen.Material and methods. The study included 434 patients hospitalized in 2018–2021. Collagen dressings were used in 280 patients (234 with II–IIIA degree burns and 46 with donor site wounds); 154 patients of the comparison group received traditional treatment in accordance with the standards of care for burns. Patients did not differ statistically significantly in age and the area of burns (general, superficial, deep). Lyophilized, sterile dressings based on type I collagen (RC No. FSR 2009/06370 December 8, 2014) were manufactured in accordance with TU No. 9393-002-01967081-2008 by the Department for Tissue Preservation and Graft Manufacturing of our Institute. We compared the timing of wound epithelialization when using collagen dressings versus the conventional treatment, and the pain intensity in the donor sites as assessed by the visual analogue scale for pain.Results. The terms of complete epithelialization of II–IIIA degree burn wounds made 10 (7;12) days when collagenbased dressings were used, and 18 (14;20) days without collagen, the difference being statistically significant (p<0.001). Epithelialization of the donor site wounds took 9 (8;10) days with using collagen dressings, and 11 (10;12) days with conventional treatment (p<0.001). The visual analogue scale assessed pain intensity in the donor site wounds after collagen application was statistically significantly lower on days 1, 4, and 7 than in patients on conventional treatment (p<0.001, p<0.001, p=0.003, respectively).Conclusion. The use of dressings based on type I allogeneic collagen for the treatment of superficial burns and the donor sites reduces the time of re-epithelialization, decreases the pain intensity in the donor site wounds, which proves the greater efficacy of this treatment method.
介绍。寻找减少供体部位烧伤和伤口治疗时间的方法目前仍具有重要意义。本回顾性研究的目的是评价异体I型胶原敷料局部治疗II-IIIA度烧伤和供区创面的效果。材料和方法。该研究包括2018-2021年住院的434名患者。280例患者使用胶原蛋白敷料(II-IIIA度烧伤234例,供区创面46例);对照组154例患者按烧伤护理标准进行传统治疗。患者在年龄和烧伤面积(全身、浅表、深部)方面无统计学差异。基于I型胶原蛋白的冻干无菌敷料。FSR 2009/06370(2014年12月8日)按照TU号9393-002-01967081-2008由我所组织保存和移植物制造部生产。我们比较了使用胶原敷料与常规治疗时伤口上皮化的时间,以及用视觉模拟疼痛量表评估供体部位的疼痛强度。II-IIIA度烧伤创面完全上皮化时间,使用胶原敷料为10(7;12)天,不使用胶原敷料为18(14;20)天,差异有统计学意义(p<0.001)。胶原敷料组创面上皮化时间为9(8;10)天,常规治疗组创面上皮化时间为11(10;12)天(p<0.001)。用视觉模拟量表评估胶原蛋白应用后供区创面疼痛强度在第1、4、7天均明显低于常规治疗组(p<0.001, p<0.001, p=0.003)。使用基于I型异体胶原的敷料治疗浅表烧伤和供区,减少了再上皮化的时间,减轻了供区伤口的疼痛强度,证明了这种治疗方法更有效。

The search for methods to reduce the time of treatment of burns and wounds of the donor sites currently remains relevant.Aim. Objective of this retrospective study was to evaluate the effectiveness of local treatment of II–IIIA degree burns and donor site wounds with dressings based on allogeneic type I collagen.Material and methods. The study included 434 patients hospitalized in 2018–2021. Collagen dressings were used in 280 patients (234 with II–IIIA degree burns and 46 with donor site wounds); 154 patients of the comparison group received traditional treatment in accordance with the standards of care for burns. Patients did not differ statistically significantly in age and the area of burns (general, superficial, deep). Lyophilized, sterile dressings based on type I collagen (RC No. FSR 2009/06370 December 8, 2014) were manufactured in accordance with TU No. 9393-002-01967081-2008 by the Department for Tissue Preservation and Graft Manufacturing of our Institute. We compared the timing of wound epithelialization when using collagen dressings versus the conventional treatment, and the pain intensity in the donor sites as assessed by the visual analogue scale for pain.Results. The terms of complete epithelialization of II–IIIA degree burn wounds made 10 (7;12) days when collagenbased dressings were used, and 18 (14;20) days without collagen, the difference being statistically significant (p<0.001). Epithelialization of the donor site wounds took 9 (8;10) days with using collagen dressings, and 11 (10;12) days with conventional treatment (p<0.001). The visual analogue scale assessed pain intensity in the donor site wounds after collagen application was statistically significantly lower on days 1, 4, and 7 than in patients on conventional treatment (p<0.001, p<0.001, p=0.003, respectively).Conclusion.
