Оценка эффективности ингибиторов ИЛ-6, а именно Тоцилизумаба, продолжается, но результаты противоречивы.</p><sec><title>Цель</title><p>Цель: выявление эффективности комплексной терапии COVID-19 с назначением препарата Тоцилизумаб.</p><p>Материалы и методы исследования. С целью выявления эффективности и критериев назначения таргетной терапии с применением Тоцилизумаба проведен ретроспективный анализ клинических и лабораторных показателей у пациентов с тяжелой формой COVID-19, в группе пациентов, получавших лечение с назначением препарата (n = 174) и группе пациентов, получавших стандартную терапию (без терапии Тоцилизумабом) (n = 70). Группы сравнения были схожи по половозрастным характеристикам.</p><p>Эффективность таргетной терапии с применением Тоцилизумаба оценивали по показателям общего и биохимического анализа крови, уровней концентрации прокальцитонина, ИЛ-6 и пресепсина, исходов заболевания.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. Средние показатели анализируемых величин (концентрация лейкоцитов, нейтрофилов п/я, АСТ, КФК-МВ, ЛДГ, креатинина, мочевины, ИЛ-6, P-SEP до терапии были вариативно выше либо ниже нормы у пациентов обеих анализируемых групп и имели статистически значимые отличия при их сравнении между группами (р &lt; 0,05). Показатели концентрации эритроцитов, гемоглобина, гематокрита, тромбоцитов, лимфоцитов, АЛТ, альбумина, КФК, общего белка, СРБ, ферритина и ПКТ не имели статистически значимых отличий между группами до назначения терапии.</p><p>Частота выживаемости при терапии с помощью тоцилизумаба была в 2,5 раза выше, чем при терапии без тоцилизумаба.</p></sec><sec><title>Выводы</title><p>Выводы. После применения Тоцилизумаба у пациентов 1 группы существенно снизился уровень концентрации СРБ (на 46,7 мг/л – 63 %), ферритина (на 366,9 мкг/л – 84 %), ПКТ (на 0,122 нг/мл – 76 %), ИЛ-6 (на 51,2 пг/мл – 93 %), P-SEP (на 225 пг/мл – 67 %), АЛТ (на 4,1 Ед/л – 9 %), АСТ (на 34,5 Ед/л – 56 %), КФК (на 121 Ед/л – 57 %).</p></sec></abstract><trans-abstract xml:lang="en"><p>Cytokine release syndrome with increased levels of interleukin-6 (IL-6) is associated with multiple organ damage and death in severe coronavirus disease. Trials to investigate the efficacy of IL-6 inhibitors, namely Tocilizumab, are ongoing with promising but conflicting results.</p><sec><title>Objective</title><p>Objective. To identify the effectiveness of complex therapy for COVID-19 with the appointment of the drug Tocilizumab.</p></sec><sec><title>Material and methods</title><p>Material and methods. In order to identify the effectiveness and criteria for prescribing targeted therapy using Tocilizumab, a statistical analysis of clinical and laboratory parameters was performed in patients with severe and moderate COVID-19, in the group of patients treated with the drug (n = 174) and the group of patients receiving standard therapy (without Tocilizumab therapy) (n = 70). The comparison groups were similar in terms of gender and age characteristics.</p><p>The effectiveness of targeted therapy with the use of tocilizumab was assessed in terms of general and biochemical blood tests, levels of procalcitonin, IL-6 and presepsin, and outcomes among patients.</p></sec><sec><title>Results</title><p>Results. The average values of the analyzed values (concentration of leukocytes, neutrophils p/n, AST, CPK-MB, LDH, creatinine, urea, IL-6, P-SEP before therapy were variably higher or lower than normal in patients of both analyzed groups and had statistically significant differences when compared between groups (p &lt; 0.05). The concentrations of erythrocytes, hemoglobin, hematocrit, platelets, lymphocytes, ALT, albumin, CPK, total protein, CRP, ferritin and PCT did not have statistically significant differences between the groups before the appointment of therapy.</p><p>All analyzed parameters showed a variable change in the end point of control, depending on the improvement of the patient’s condition or death. At the same time, the stabilization of leukocytes, neutrophils p/I, ALT, AST, CPK-MB, creatinine, CPK, ferritin, PCT, IL-6 and P-SEP in the tocilizumab therapy group was noted compared with the baseline and indicators of the comparison group.</p><p>The expected survival rate for therapy with tocilizumab was 2.5 times higher than for therapy without Tocilizumab.</p></sec><sec><title>Conclusion</title><p>Conclusion. After the use of Tocilizumab in patients of group 1, the level of CRP concentration significantly decreased (by 46.7 mg/l – 63 %), ferritin (by 366.9 µg/l – 84 %), PCT (by 0.122 ng/ml – 76 %), IL-6 (by 51.2 pg/ml – 93 %), P-SEP (by 225 pg/ml – 67 %), (by 4.1 U/l – 9 %), AST (by 34.5 U/l – 56 %), CPK (by 121 U/l – 57 %).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>интерлейкин-6</kwd><kwd>цитокиновый шторм</kwd><kwd>моноклональные антитела</kwd><kwd>Тоцилизумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>interleukin-6</kwd><kwd>cytokine storm</kwd><kwd>monoclonal antibodies</kwd><kwd>Toci- lizumab</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wiersinga, W.
