Оценить возможность использования лабораторного определения цитокератина-18 в комплексной диагностике хронических заболеваний почек у детей.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 137 пациентов с хроническими заболеваниями почек. В группу сравнения вошли условно здоровые дети без признаков поражения почек и аутоиммунного процесса. Количественное определение уровня цитокератина-18 проводили методом иммуноферментного анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Отмечены различия концентраций цитокератина-18 в сыворотке крови пациентов всех групп (р &lt; 0,001). В моче различия содержания цитокератина-18 по тесту Краскела — Уоллиса также показали статистическую значимость (р &lt; 0,001). При уровне цитокератина-18 более 0,07 в сыворотке крови отношение шансов риска хронических заболеваний почек (ОШ) — 34,04 (95 % ДИ (9,5—122)). ROC-анализ показал диагностическую точность 85,0 % (95 % ДИ (76,9—93,1)), чувствительность — 81,6 %, специфичность — 88,5 %. При уровне цитокератина-18 более 0,09 в моче ОШ — 26,5 (95 % ДИ (8,4—84,3)), диагностическая точность — 83,7 % (95 % ДИ (74,9—92,6)), чувствительность — 73,8 %, специфичность — 84,6 %.</p></sec><sec><title>Заключение</title><p>Заключение. Определение уровня цитокератина-18 в сыворотке крови и моче может быть использовано в диагностике хронических заболеваний почек у детей, в том числе для дифференциальной диагностики гломерулярных и негломерулярных хронических заболеваниях почек, а также гломерулопатий между собой. Однако использование этого маркера апоптоза для прогнозирования прогрессирования заболевания и оценки тяжести процесса на данном этапе исследования не представляется возможным.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the possibility of using laboratory determination of cytokeratin-18 in the complex diagnosis of chronic kidney diseases in children.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 137 patients with chronic kidney diseases were examined. The comparison group included conditionally healthy children without signs of kidney damage and autoimmune process. Quantitative determination of cytokeratin-18 levels was performed by enzyme immunoassay.</p></sec><sec><title>Results</title><p>Results. Differences in cytokeratin-18 concentrations in the blood serum of patients of all groups (p &lt; 0.001), were noted. Differences in cytokeratin-18 levels in urine according to the Kraskel — Wallis test also showed statistical significance (p &lt; 0.001). When the cytokeratin-18 level is &gt; 0.07 in the blood serum, the odds ratio of the risk of chronic kidney disease (OR) is 34.04 (95 % CI (9.5—122)). ROC analysis showed diagnostic accuracy of 85.0 % (95 % CI (76.9—93.1)), sensitivity — 81.6 %, specificity — 88.5 %. With cytokeratin-18 levels &gt; 0.09 in urine, the OR was 26.5 (95 % CI (8.4—84.3)), diagnostic accuracy was 83.7 % (95 % CI (74.9—92.6)), sensitivity was 73.8 %, and specificity was 84.6 %.</p></sec><sec><title>Conclusion</title><p>Conclusion. Determination of cytokeratin-18 levels in the blood serum and urine of pediatric patients can be used in the diagnosis of chronic kidney diseases in children, including for the differential diagnosis of glomerular and non-glomerular chronic kidney diseases, as well as glomerulopathies among themselves. However, it is not possible to use this marker of apoptosis to predict the progression of the disease and assess the severity of the process at this stage of the study.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цитокератин-18</kwd><kwd>апоптоз</kwd><kwd>хронические заболевания почек</kwd><kwd>дети</kwd><kwd>гломерулопатии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cytokeratin-18</kwd><kwd>apoptosis</kwd><kwd>chronic kidney disease</kwd><kwd>children</kwd><kwd>glomerulopathies</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">Bertheloot, D.
