Существует важность выявления и уточнения роли, клинических и лабораторных показателей в оценке неблагоприятного прогноза COVID-19, позволяющая выявить пациентов из группы риска на ранней стадии патологического процесса.</p><p>Целью данной работы явилось выявление клинических и лабораторных предикторов, влияющих на ухудшение прогноза и летальность при COVID-19.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование проводилось на базе УЗ «5-я городская клиническая больница» г. Минска, в котором участвовало 240 пациентов с тяжелой формой COVID-19.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам исследования в группе умерших преобладали лица более старшей возрастной группы, средний показатель коморбидности патологий в группе выживших составил 2 патологии (max 7, min 0), в группе умерших – 2 патологии (max 10, min 0, Ме 3), что имело статистически достоверную разницу на уровне р = 0,00006. Среди осложнений чаще всего регистрировали ДН 1–3 степени (у 84,87 % выживших пациентов и 71,9 % у умерших пациентов), отек легких (у 2,52 и 12,4 % пациентов соответственно), СПОН (у 5,88 и 19,83 % пациентов соответственно). Снижение SрO2 менее 93 % существенно снижало шансы на выздоровление (ОШ 0,422; 95 % ДИ 0,138–0,637). Повышение уровня СРБ &gt; 5 мг/л имело значимую сопряженность с неблагоприятным исходом COVID-19 (ОШ 2,721; 95 % ДИ 1,342–6,657).</p></sec><sec><title>Заключение</title><p>Заключение: факторами, влияющими на прогноз при COVID-19, оказались более старший возраст, десатурация менее 93 % (χ2 = 245,211; p &lt; 0,0001), высокий процент коморбидности р = 0,00006 (р &lt; 0,05), лейкоцитоз (χ2 = 18,36; p &lt; 0,001), повышение уровня С-реактивного белка (χ2 = 132,455; p &lt; 0,001), прокальцитонина, ИЛ-6, D-димеры (χ2 = 161,122; p &lt; 0,001).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Identification and clarification of the role of clinical and laboratory indicators in assessing the unfavorable prognosis of COVID-19 is important, allowing to identify patients at risk at an early stage of the pathological process.</p><p>The purpose of this work was to identify clinical and laboratory predictors that influence worsening prognosis and mortality in COVID-19.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was conducted at the 5th City Clinical Hospital in Minsk, which involved 240 patients with severe COVID-19.</p></sec><sec><title>Results</title><p>Results. According to the results of the study, in the group of the deceased persons of older age group prevailed, the average index of comorbidity of pathologies in the group of the survivors was 2 pathologies (max 7, min 0), in the group of the deceased – 2 pathologies (max 10, min 0, Me 3), which had statistically significant difference at the level of p = 0.00006. Among complications, the most frequently recorded were DN 1–3 degree (in 84.87 % of surviving patients and 71.9 % of deceased patients), pulmonary edema (in 2.52 and 12.4 % of patients, respectively), SPON (in 5.88 and 19.83 % of patients, respectively). A decrease in SrO2 less than 93 % significantly reduced the chances of recovery (OR 0.422; 95 % CI 0.138–0.637). An elevated CRP level &gt; 5 mg/L had a significant association with unfavorable COVID-19 outcome (OR 2.721; 95 % CI 1.342–6.657).</p></sec><sec><title>Conclusion</title><p>Conclusion: factors affecting prognosis in COVID-19 turned out to be older age, desaturation less than 93 % (χ2 = 245.211; p &lt; 0.0001), high percentage of comorbidity p = 0.00006 (p &lt; 0.05), leukocytosis (χ2 = 18.36; p &lt; 0.001), increased levels of C-reactive protein (χ2 = 132.455; p &lt; 0.001), procalcitonin, IL-6, D-dimers (χ2 = 161.122; p &lt; 0.001).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>коморбидность</kwd><kwd>лимфоцитопения</kwd><kwd>десатурация</kwd><kwd>ИЛ-6</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>comorbidity</kwd><kwd>lymphocytopenia</kwd><kwd>desaturation</kwd><kwd>IL-6</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">Биомаркеры тяжести течения COVID-19: сравнение собственных результатов с данными литературы / У.
