Диагностика ранней стадии хронической болезни почек (ХБП) является глобальной проблемой, поскольку чаще диагностируются поздние стадии заболевания. Разработка методов моделирования для принятия управленческих решений, направленных на повышение эффективности ранней диагностики ХБП, является важной научно-практической задачей, в решении которой большую поддержку может оказать использование алгоритмов машинного обучения (MLA).</p></sec><sec><title>Цель</title><p>Цель.

Данные были получены из одноцентрового ретроспективного катамнестического когортного исследования (2011–2022 гг.) детей с ХБП 1-4 стадии в возрасте от 1 до 17 лет. В основную группу включены 128 детей с хроническими заболеваниями почек, в группу сравнения – 30 детей без патологии почек. Дети двух групп статистически значимо не различались по полу и возрасту. Для построения модели диагностики ХБП использованы данные анамнеза, клинико-инструментального и генетического обследования. Модель построена с применением MLA многофакторная логистическая регрессия (MLR).

Diagnosis of early-stage chronic kidney disease (CKD) is a global challenge, as late-stage disease is more commonly diagnosed. The development of modeling methods for making management decisions aimed at improving the eﬃciency of early diagnosis of CKD is an important scientiﬁc and practical task, which can be greatly supported by the use of machine learning algorithms (MLA).</p></sec><sec><title>Aim</title><p>Aim. To improve the accuracy of diagnosis of CKD using data from history, clinical-instrumental, genetic examination and machine learning algorithms (MLA).</p></sec><sec><title>Methods</title><p>Methods. Data were obtained from a single-center retrospective catamnestic cohort study (2011–2022) of children with CKD stage 1–4 aged 1 to 17 years. The main group included 128 children with CKD, and the comparison group included 30 children without any kidney disease. Two groups were comparable by sex and age. The data of anamnesis, clinical-instrumental and genetic examination were used to build a model for CKD diagnosis. The model was built using the MLA multivariate logistic regression (MLR). Three variables were used in the model: erythrocyte sedimentation rate in blood (β = 0,392; p&lt;0,001).</p></sec><sec><title>Results</title><p>Results. A diagnostics model was obtained allowing prediction of CKD on a test sample with accuracy of 90,3% [80,6; 96,8], sensitivity of 92,0% [81,5; 100,0], speciﬁcity of 83,3% [50,0; 100,0], ROC-AUC = 90,0% [77,2; 100,0]. The resulting model is of excellent quality (&gt;90%) as the ROC-AUC is 0,90 on the test sample. The cut-oﬀ point value of the probability of CKD is 0,25.</p></sec><sec><title>Conclusions</title><p>Conclusions. We developed and tested the model that diagnoses early-stage CKD in children with high accuracy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая болезнь почек у детей</kwd><kwd>машинное обучение</kwd><kwd>ранняя диагностика</kwd><kwd>боль в животе</kwd><kwd>вероятность</kwd><kwd>многофакторная логистическая регрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>сhronic kidney disease in children</kwd><kwd>machine learning</kwd><kwd>early diagnosis</kwd><kwd>abdominal pain</kwd><kwd>probability</kwd><kwd>multivariate logistic regression</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">Бодрин К.А., Красноперова А.А.
