Оценивали различие лабораторных показателей (общеклинические, биохимические и иммунологические) в зависимости от степени поражения легких (до 25 и до 50%). Группа сравнения – 20 здоровых добровольцев.</p></sec><sec><title>Результаты</title><p>Результаты: различия между пациентами с различной площадью поражения лёгких заключались в более высоких уровнях маркеров тяжести прогноза (СРБ, ЛДГ). В иммунном статусе в группе КТ-2 снижение CD3+ лимфоцитов и их хелперной субпопуляции, дисиммуноглобулинемия и более высокое содержание ИЛ-6.</p></sec><sec><title>Выводы</title><p>Выводы: КТ-исследование имеет большое значение для мониторинга прогрессирования заболевания. Меньшая площадь поражения лёгких отражает более лёгкое течение заболевания, что не исключает необходимости диспансерного наблюдения и реабилитации после выписки.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the clinical and immunological parameters of patients with COVID-19 in moderate form with varying degrees of lung tissue damage.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: 80 patients hospitalized with a diagnosis of «COVID-19, moderate form; complication: bilateral polysegmental interstitial pneumonia» were examined. The difference in laboratory parameters (general clinical, biochemical and immunological) was evaluated depending on the degree of lung damage (up to 25 and up to 50%). Comparison group: 20 healthy volunteers.</p></sec><sec><title>Results</title><p>Results: the differences between patients with different lung lesion areas consisted in higher levels of prognosis severity markers – CRP, LDH. In the immune status in the CT group 2, there was a decrease in CD3+ lymphocytes and their helper subpopulation, dysimmunoglobulinemia and a higher IL-6 content.</p></sec><sec><title>Conclusions</title><p>Conclusions: CT examination is of great importance for monitoring the progression of the disease. The smaller area of lung lesion reflects a lighter course of the disease, which does not exclude the need for dispensary observation and rehabilitation after discharge.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронавирусная инфекция</kwd><kwd>COVID-19</kwd><kwd>компьютерная томограмма лёгких</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronavirus infection</kwd><kwd>COVID-19</kwd><kwd>computed tomography of the lungs</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">Coutard B, Valle C, de Lamballerie X, Canard B, Seidah NG, Decroly E.
