Среди её важнейших аспектов, требующих тщательного анализа, клинико-лабораторные особенности течения заболевания, позволяющие определить подходы к патогенетической терапии при тяжелых формах заболевания. Материалы и методы. Проведен ретроспективный анализ медицинских карт больных (n=31) COVID-19 тяжелого течения, находившихся на стационарном лечении в Клинической инфекционной больнице им. С.П. Боткина в марте – мае 2020 г. Оценена клинико-лабораторная характеристика, включая уровень ферритина, С-реактивного белка, D-димера, интерлейкина-6, в зависимости от тяжести заболевания. Определены критерии назначения рекомбинантного гуманизированного моноклонального антитела к человеческому рецептору интерлейкина-6 (МНН – тоцилизумаб) у пациентов с тяжелым течением заболевания и его эффективность. Результаты. При лечении тяжелых пациентов с COVID-19 необходимо тщательно оценивать клиническую картину течения заболевания, которая может опережать изменения в лабораторных показателях. Введение тоцилизумаба приводит к быстрому регрессу общеинфекционной симптоматики, субъективных и объективных проявлений дыхательной недостаточности и, как следствие, уменьшению длительности госпитализации. Крайне важно своевременное упреждающее введение препарата в период нарастания «цитокинового шторма». Время оптимального назначения тоцилизумаба начинается с 8–9-го дня от начала заболевания, до перевода пациента на ИВЛ.</p></abstract><trans-abstract xml:lang="en"><p>The new coronavirus infection (COVID-19) has become a truly global challenge for all of humanity, and, above all, for the healthcare system. Among its most important aspects requiring careful analysis are the clinical and laboratory features of the course of the disease, which make it possible to determine approaches to pathogenetic therapy in severe forms of the disease. Materials and methods. A retrospective analysis of medical records of patients (n = 31) of severe COVID-19 patients who were hospitalized in St. Petersburg City Clinical Hospital for Infectious Diseases named after S.P. Botkin ”in March – May 2020. Clinical and laboratory characteristics were evaluated, including the level of ferritin, C-reactive protein, D-dimer, interleukin-6, depending on the severity of the disease. The criteria for the appointment of a recombinant humanized monoclonal antibody to the human receptor for interleukin-6 (INN – tocilizumab) in patients with a severe course of the disease and its effectiveness are determined. Results. In the treatment of severe patients with COVID-19, it is necessary to carefully evaluate the clinical picture of the course of the disease, which may be ahead of changes in laboratory parameters. The introduction of tocilizumab leads to a rapid regression of general infectious symptoms, subjective and objective manifestations of respiratory failure and, as a consequence, a decrease in the duration of hospitalization. It is extremely important that the drug is administered in a timely manner during the rise of the “cytokine storm”. The time for optimal administration of tocilizumab begins from 8-9 days from the onset of the disease, until the patient is transferred to mechanical ventilation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>генерализация вирусной инфекции</kwd><kwd>иммунопатологические механизмы</kwd><kwd>лечение</kwd><kwd>тоцилизумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>generalization of viral infection</kwd><kwd>immunopathological mechanisms</kwd><kwd>treatment</kwd><kwd>tocilizumab</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">Пшеничная, Н.Ю.
