Изучить прогностическое значение цистатина С (CysC) для оценки вероятности летального исхода у больных с пневмонией тяжелого и крайне тяжелого течения, ассоциированной с COVID-19.Материал и методы. Провели одноцентровое проспективное исследование, включающее 72 больных с пневмонией тяжелого и крайне тяжелого течения, ассоциированной с COVID-19, получавших лечение с сентября 2020 г. по октябрь 2021 г. в отделении реанимации и интенсивной терапии многофункционального медицинского центра. Выделили две группы: 1-я группа — выздоровевшие (n=55), 2-я группа — больные с летальным исходом (n=17).Результаты. Концентрация CysC в сыворотке крови (s-CysC) и в моче (u-CysC) пациентов 1-й группы была значимо ниже, чем у пациентов 2-й группы и составила в среднем 1,31 мг/мл против 1,695 мг/л (p=0,013550) и 0,25 мг/л против 0,94 мг/л (p=0,026308), соответственно. Выявили значимые межгрупповые различия по возрасту (p=0,0094), количеству тромбоцитов (p=0,001) и концентрации фибриногена (p=0,016) в крови, по количеству баллов шкал CURB, p=0,02334, CRB-65, p=0,032564 и SOFA, p=0,042042. Продемонстрировали, что s-CysC и u-CysC являются статистически значимыми предикторами летального исхода при пневмонии, ассоциированной с тяжелым и крайне тяжелым течением COVID-19: 16,273 (95% ДИ, 2,503–105,814), p=0,003 и 1,281 (95% ДИ, 1,011–1,622), p=0,040, соответственно. Установили, что u-CysC — высокоинформативный (ROC AUC 0,938 (95% ДИ, 867–1,000; p=0,000), чувствительность 90%, специфичность 90%), а s-CysC — информативный (ROC AUC 0,863 (95%ДИ, 738–0,988; p=0,000), чувствительность 80% и специфичность 72%) предикторы летального исхода при пневмонии, ассоциированной с тяжелым и крайне тяжелым течением COVID-19.Заключение. s-CysC и u-CysC обладают высокой прогностической значимостью и позволяют выявить больных с высоким риском развития неблагоприятного исхода (смерти) при пневмонии, ассоциированной с тяжелым и крайне тяжелым течением COVID-19. Увеличение концентрации s-CysC до 1,44 мг/л и выше и u-CysC — до 0,86 мг/л и выше, ассоциировано с высокой вероятностью наступления летального исхода.</p></abstract><trans-abstract xml:lang="en"><p>Objective. To assess the cystatin C (CysC) prognostic value for probability of death in patients with severe and extremely severe pneumonia associated with COVID-19.Material and methods. A single-center prospective study included 72 patients with severe and extremely severe pneumonia associated with COVID-19 undergoing treatment in the ICU of multifunctional medical center from September 2020 to October 2021. Recovered survivors (N=55) were analyzed as a Group 1, nonsurvivors (N=17) were considered as a Group 2.Results. The serum (s-CysC) and urine (u-CysC) CysC concentrations were significantly lower in Group 1 patients vs Group 2, averaging 1.31 mg/l vs 1.695 mg/l (P=0.013550), and 0.25 mg/l vs 0.94 mg/l (P=0.026308), respectively. Significant differences were also revealed in the subgroups differed by age (P=0.0094), platelet count (P=0.001), serum fibrinogen concentration (P=0.016), as well as CURB (P=0.02334), CRB-65 (P=0.032564), and SOFA (P=0.042042) scores. Therefore, s-CysC and u-CysC were statistically significant predictors of death in patients with pneumonia associated with severe and extremely severe COVID-19: 16.273 (95% CI: 2.503–105,814), P=0.003 and 1.281 (95% CI: 1.011–1.622), P=0.040, respectively. Urine and serum CysC were established as predictors of death in pneumonia associated with severe and extremely severe COVID-19, where u-CysC was defined as highly informative (ROC AUC 0.938 (95% CI: 0.867–1.000; P=0.000), with 90% sensitivity and specificity), and s-CysC — as informative (ROC AUC 0.863 (95%CI: 0.738–0.988; P=0.000) with 80% sensitivity and 72% specificity) predictive markers.Conclusion. Levels of S-CysC and u-CysC are of high prognostic significance and may contribute to identifying patients at a high risk of unfavorable outcome (death) due to pneumonia associated with severe and extremely severe COVID-19. Both S-CysC and u-CysC concentrations increasing up to 1.44 mg/l and 0.86 mg/l, respectively, were associated with high probability of death.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цистатин-С</kwd><kwd>предиктор</kwd><kwd>пневмония</kwd><kwd>коронавирусная инфекция</kwd><kwd>COVID-19</kwd><kwd>смерть</kwd><kwd>летальный исход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystatin C</kwd><kwd>predictor</kwd><kwd>pneumonia</kwd><kwd>coronavirus infection</kwd><kwd>COVID-19</kwd><kwd>death</kwd><kwd>fatal outcome</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">Хаджиева М.Б., Грачева А.С., Ершов А.В., Чурсинова Ю.В., Степанов В.А., Авдейкина Л.С., Гребенчиков О.А., с соавт.
