Выявление особенностей поражений лёгких при таких заболеваниях является актуальным в период распространения сезонных респираторных инфекций. Изучение динамики гематологических и гемостазиологических параметров крови у пациентов с пневмониями различного генеза в сравнительном аспекте представляет интерес в плане поиска предикторов прогноза развития заболеваний.</p><sec><title>Цель</title><p>Цель. Сравнить особенности клинической симптоматики, гематологических и гемостазиологических показателей у пациентов с пневмонией, вызванной COVID-19, и у пациентов с внебольничной пневмонией. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Сформировано две группы: 1-я группа – 92 пациента с диагнозом «внебольничная пневмония, вызванная инфекцией COVID-19, средней тяжести», 2-я группа – 40 пациентов с диагнозом«внебольничная двусторонняя полисегментарная пневмония средней тяжести» в рамках одномоментного  (cross-sectional)  исследования.</p></sec><sec><title>Результаты</title><p>Результаты. Было выявлено, что группа пациентов с COVID-19 характеризовалась более старшим возрастом (69 лет vs 39,3 года), более низкой температурой тела при поступлении (37,5 °C vs 38,85 °C), меньшим процентом сниженной сатурации кислорода (менее 89 % в 5,4 % случаев vs 10 % случаев). В большинстве случаев средние значения ряда гематологических показателей у пациентов с COVID-19 не выходили за рамки референсных. Лейкопения (ниже 4 × 109 кл./л) и лимфопения (ниже 1,1 × 109 кл./л) наблюдались в 26 % и 38 % случаев соответственно, тромбоцитопения (менее 100 × 109 кл./л) – в 12,2 %, гиперфибриногенемия (более 4 г/л) – в 65,3 % случаев. Выявлена прямая корреляционная связь уровней тромбоцитов с лейкоцитами (R = 0,53; p &lt; 0,001) и лимфоцитами (R = 0,29; p = 0,06). По сравнению с пациентами 2-й группы, в среднем по группе пациентов с COVID-19 наблюдались значительно более низкие значения уровней лейкоцитов и лимфоцитов (в 2,5 раза каждый; р &lt; 0,001) и повышенный уровень фибриногена (на 45 %; р &lt; 0,001).</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с пневмонией, вызванной COVID-19, выявлены особенности клинической симптоматики, гематологических и гемостазиологических показателей крови относительно внебольничной неспецифической  пневмонии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Against the background of priority attention paid to the COVID-19 pandemic, there are also cases of community-acquired pneumonia of a different genesis. Identification of the features of lung lesions in such diseases is relevant during the spread of seasonal respiratory infections. The comparative study of the dynamics of hematological and hemostasiological parameters of blood in patients with pneumonia of various origins is of interest in terms of searching for predictors of the prognosis of the diseases development.</p><sec><title>Aim</title><p>Aim. To compare the features of clinical symptoms, hematological and hemostasiological parameters in patients with pneumonia caused by COVID-19 and in patients with community-acquired pneumonia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. During cross-sectional study two groups were formed: group 1 consisted of 92 patients diagnosed with moderate community-acquired pneumonia caused by COVID-19 infection; group 2 included 40 patients diagnosed with moderate community-acquired bilateral polysegmental pneumonia.</p></sec><sec><title>Results</title><p>Results. It was found that patients with COVID-19 had an older age (69 vs 39.3 years), a lower body temperature at admission (37.5 vs 38.85 °C), a lower percentage of reduced oxygen saturation (less than 89 % in 5.4 % of cases vs 10 % of cases). In most cases, the average values of some hematological parameters in patients with COVID-19 did not go beyond the reference range. Leukopenia (below 4 × 109 cells/l) and lymphopenia (below 1.1 × 109 cells/l) were observed in 26 % and 38 % of cases respectively; thrombocytopenia (less than 100 × 109 cells/l) – in 12.2 % of cases; hyperfibrinogenemia (more than 4 g/l) – in 65.3 % of cases. A direct correlation was found between platelet levels and leukocytes (R = 0.53; p &lt; 0.001) and lymphocytes (R = 0.29; p = 0.06). Compared with the patients of the group 2,on average, patients with COVID-19 had significantly lower levels of leukocytes and lymphocytes (2.5 times each; p &lt; 0.001) and an increased level of fibrinogen (by 45 %; p &lt; 0.001).</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients with pneumonia caused by COVID-19, we revealed the particular features of clinical symptoms, hematological and hemostasiological blood parameters compared to community-acquired nonspecific pneumonia.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>коронавирусная инфекция</kwd><kwd>COVID-19</kwd><kwd>внебольничная пневмония</kwd><kwd>анализ крови</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronavirus infection</kwd><kwd>pandemic</kwd><kwd>COVID-19</kwd><kwd>computed tomography</kwd><kwd>pneumonia</kwd><kwd>hemostasiological analysis</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">Львов Д.К., Альховский С.В., Колобухина Л.В., Бурцева Е.И.
