Всем пациентам выполнены общий анализ крови, определение уровня С-реактивного белка (СРБ), компьютерная томография (КТ) легких. Тяжесть клинического состояния оценивалась по шкалам ШОКС-КОВИД и NEWS-2.</p></sec><sec><title>Результаты</title><p>Результаты: более тяжёлое клиническое состояние пациентов и большая выраженность поражения легких при поступлении были статистически значимо ассоциированы со снижением количества эритроцитов и гемоглобина, а также с большей шириной распределения эритроцитов (RDW-SD). Скорость оседания эритроцитов (СОЭ) была статистически значимо связана с клиническим состоянием пациентов, оценённым по ШОКС-КОВИД (r=0,61, р&lt;0,001) и маркером воспаления СРБ (r=0,55, р&lt;0,001). Повышение абсолютного числа нейтрофилов (N), снижение абсолютного числа лимфоцитов (L) и, как следствие, увеличение индекса соотношения N/L были маркерами более тяжёлого течения заболевания. Именно индекс N/L имел максимальный коэффициент корреляции с наиболее часто используемым маркером системного воспаления СРБ (r=0,50, р&lt;0,001). Снижение уровня СРБ к выписке было связано со статистически значимым снижением СОЭ (r=0,36, р&lt;0,001), индекса соотношения уровней нейтрофилов и лимфоцитов (N/L) (r=0,39, р&lt;0,001), увеличением ширины распределения эритроцитов (RDW-SD r=0,25, р&lt;0,01; RDW-CV r=0,57, р&lt;0,001).</p></sec><sec><title>Выводы</title><p>Выводы: наиболее информативными показателями общего анализа крови при поступлении в стационар, позволяющими оценить тяжесть течения заболевания, являются ширина распределения эритроцитов, индекс соотношения нейтрофилов к лимфоцитам и СОЭ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: to study the relationship of the indicators of the general blood test with the severity of the course of COVID-19 in hospitalized patients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: the study included 165 patients (92 men — 55.8%, and 73 women — 44.2%, the average age — 59.9 years) who were treated at the Moscow State University Medical Center in the period from April to June 2020 with a diagnosis of COVID-19. All patients underwent: general blood test, CRP, CT of the lungs. The severity of the clinical condition was assessed using the SHOCK-COVID and NEWS-2 scales.</p></sec><sec><title>Results</title><p>Results: a more severe clinical condition of patients and a greater severity of lung damage on admission were statistically significantly associated with a decrease in the number of red blood cells and hemoglobin, as well as with a greater width of the distribution of red blood cells (RDW-SD). The rate of erythrocyte sedimentation (ESR) was significantly associated with the clinical condition of patients evaluated by SHOCK-COVID (r=0.61, p&lt;0.001) and the marker of CRP inflammation (r=0.55, p&lt;0.001). An increase in the absolute number of neutrophils (N), a decrease in the absolute number of lymphocytes (L), and, as a result, an increase in the N/L ratio index was a marker of a more severe course of the disease. It was the N/L index that had the maximum correlation coefficient with the most commonly used marker of systemic inflammation - CRP (r=0.50, p&lt;0.001). The decrease in the level of CRP by discharge was associated with a significant decrease in ESR (r=0.36, p&lt;0.001), the index of the ratio of neutrophil and lymphocyte levels (N/L) (r=0.39, p&lt;0.001), and an increase in the width of the distribution of red blood cells (RDW-SD r=0.25, p&lt;0.01; RDW-CV r=0.57, p&lt;0.001).</p></sec><sec><title>Conclusions</title><p>Conclusions: the most informative indicators of the general blood test at admission to the hospital, allowing to assess the severity of the disease — the width of the distribution of red blood cells, the index of the ratio of neutrophils to lymphocytes and ESR.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>общий анализ крови</kwd><kwd>RDW</kwd><kwd>СОЭ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>general blood test</kwd><kwd>RDW</kwd><kwd>ESR</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">Мареев В.
