Patients were classified as having normal renal function (≥90 ml/min/1.73 m<sup>2</sup>) and impaired renal function (≤89 ml/min/1.73 m<sup>2</sup>).</p> <p><bold>Results.</bold> Patients with impaired renal function were significantly older, had higher body mass index (BMI) and lung injury compared to patients with normal renal function. Patients with decreased GFR had hematological abnormalities, such as increased hematocrit and decreased lymphocyte count. These changes were especially pronounced in men and diabetic patients, indicating possible inflammatory and metabolic effects on kidney injury in these groups.</p> <p><bold>Conclusion. </bold>Older age, increased BMI and signigicant lung injury were significant predictors of renal injury in patients with COVID-19, especially in diabetic patients. Regular assessment of GFR and early management of inflammatory processes may be key to preventing renal complications in this category of patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования: </bold>улучшить понимание предикторов риска почечных осложнений у пациентов, перенесших COVID-19, с сахарным диабетом (СД) и без него, что позволит разработать эффективные стратегии профилактики и лечения.</p> <p><bold>Материал и методы. </bold>В исследовании участвовали 386 пациентов, которые были разделены на группы в зависимости от скорости клубочковой фильтрации (СКФ), рассчитанной с использованием формулы CKD-EPI. Пациенты были классифицированы как имеющие нормальную функцию почек (≥90 мл/мин/1,73 м<sup>2</sup>) и нарушенную функцию почек (≤89 мл/мин/1,73 м<sup>2</sup>).</p> <p><bold>Результаты. </bold>Пациенты с нарушенной функцией почек были значительно старше, имели больший индекс массы тела (ИМТ) и степень поражения легких по сравнению с пациентами с нормальной функцией почек. У пациентов с пониженным уровнем СКФ наблюдались гематологические отклонения, такие как повышенный уровень гематокрита и сниженное число лимфоцитов. Эти изменения были особенно выражены у мужчин и пациентов с СД, что указывает на возможное воспалительное и метаболическое влияние на повреждение почек в этих группах.</p> <p><bold>Заключение. </bold>Пожилой возраст, повышенный ИМТ и большая степень поражения легких являются значимыми предикторами почечного повреждения у пациентов, перенесших COVID-19, особенно у больных СД. Регулярная оценка СКФ и раннее управление воспалительными процессами могут быть ключевыми в предотвращении почечных осложнений у пациентов этой категории.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>renal dysfunction</kwd><kwd>diabetes mellitus</kwd><kwd>risk factors</kwd><kwd>glomerular filtration rate</kwd><kwd>body mass index</kwd><kwd>hematological parameters</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>почечная дисфункция</kwd><kwd>сахарный диабет</kwd><kwd>факторы риска</kwd><kwd>скорость клубочковой фильтрации</kwd><kwd>индекс массы тела</kwd><kwd>гематологические параметры</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jewell P.D., Bramham K., Galloway J., et al.
