Оценить концентрацию натрия в моче больных COVID-19 с острым повреждением почек.Материал и методы. В исследование, проведённое на базе Республиканской клинической инфекционной больницы г. Ижевска в 2020-2021 гг., включено 52 больных COVID-19: 24 человека без клинико-лабораторных признаков острого повреждения почек, 14 – с преренальным, 14 – с ренальным острым повреждением почек. Концентрация натрия в моче определялась на 3-и – 5-е сутки после госпитализации. В контрольную группу включено 11 лиц практически здоровых, не инфицированных SARS-CoV-2.Результаты. Повышение концентрации натрия в моче по сравнению с контрольной группой наблюдалось не только у больных COVID-19 с острым повреждением почек, но и у больных COVID-19 без признаков нефропатии (p&lt;0,001). Различий концентрации натрия в моче между подгруппами пациентов с преренальным и ренальным острыми повреждениями почек, а также без манифестной нефропатии не было выялено.Заключение. Не выявлено диагностическое значение определения концентрации натрия в моче для дифференциальной диагностики преренального и ренального острых повреждений почек у пациентов с COVID-19. Повышенная концентрация натрия в моче у больных коронавирусной инфекцией без признаков острого повреждением почек по сравнению со здоровыми лицами может свидетельствовать о вероятном развитии у них субклинического поражения проксимальных канальцев почек.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To evaluate the urinary sodium concentration in COVID-19 patients with acute kidney injury.Material and methods. The study, conducted at the Republican Clinical Infectious Diseases Hospital in Izhevsk in 2020-2021, included 52 patients with COVID-19: 24 people without clinical and laboratory signs of acute kidney injury, 14 with prerenal acute kidney injury, 14 with renal acute kidney injury. Sodium concentration in urine was determined on days 3-5 after hospitalization. The control group included 11 healthy people not infected with SARS-CoV-2.Results. An increase in urinary sodium concentration compared to the control group was observed not only in COVID-19 patients with acute kidney injury, but also in patients with COVID-19 without signs of nephropathy (p&lt;0.001). There were no differences in urinary sodium concentrations between the subgroups of patients with prerenal and renal acute kidney injury, as well as without overt nephropathy.Conclusion. The diagnostic value of determining the concentration of sodium in urine for the differential diagnosis of prerenal and renal acute kidney injury in patients with COVID-19 has not been identified. An increased concentration of sodium in urine in patients with coronavirus infection without signs of acute kidney damage compared to healthy individuals may indicate the probable development of subclinical damage to the proximal tubules.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>острое повреждение почек</kwd><kwd>концентрация натрия в моче</kwd><kwd>цистатин C</kwd><kwd>липокалин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>acute kidney injury</kwd><kwd>urinary sodium concentration</kwd><kwd>cystatin C</kwd><kwd>lipocalin</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">Шамхалова М.Ш.
