Несмотря на несколько зарубежных исследований, данная проблема остается неизученной в достаточной мере. Результаты представленного обзорного исследования демонстрируют недостаточность информации по многим важным аспектам вторично резистентного нефротического синдрома. В частности, остаются неизвестными истинные причины и патогенез резистентности к глюкокортикостероидам, несмотря на давнее существование этой проблемы в педиатрической нефрологии. С одной стороны, такие пациенты клинически схожи с пациентами со стероид-резистентным нефротическим синдромом, но при этом имеют в целом относительно благоприятный исход. С другой стороны, неоднозначный ответ на стероидную и иммуносупрессивную терапию препятствуют разработке единой концепции заболевания и патогенетической терапии. Таким образом, важная задача для будущих исследований состоит в поиске причин развития поздней (вторичной) стероидной резистентности и на основании этого разработке и широком внедрении в клиническую практику персонифицированного терапевтического подхода к ведению детей.</p></abstract><trans-abstract xml:lang="en"><p>The concept of the steroid resistance in children with nephrotic syndrome, who were initially sensitive to steroids, has been known for a long time. Despite several foreign studies, this problem remains largely unexplored. The results of the presented review demonstrate a lack of information on many important aspects of resistant nephrotic syndrome. In particular, the true causes and pathogenesis of glucocorticosteroid resistance remain unknown, despite the long history of this problem in pediatric nephrology. On the one hand, such patients are clinically similar to the patients with steroid-resistant nephrotic syndrome, but at the same time they have a relatively favorable outcome in general. On the other hand, the ambiguous response to the steroid and immunosuppressive therapy hinders the development of a unified concept of the disease and pathogenetic therapy. Thus, an important task for future research is to find the reasons for the development of late (secondary) steroid resistance and, to develop and implement a personalized therapeutic approach to the management of children into clinical practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>стероид-резистентный нефротический синдром</kwd><kwd>вторичная стероидная резистентность</kwd><kwd>болезнь минимальных изменений</kwd><kwd>фокальный сегментарный гломерулосклероз</kwd><kwd>глюкокортикостероиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>steroid-resistant nephrotic syndrome</kwd><kwd>secondary steroid resistance</kwd><kwd>minimal change disease</kwd><kwd>focal segmental glomerulosclerosis</kwd><kwd>glucocorticosteroids</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках финансирования Госзадания «Клинические и молекулярно-генетический критерии прогнозирования эффективности стероидной и иммуносупрессивной терапии первичного нефротического синдрома у детей» № 200080056.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of funding from the State Assignment “Clinical and molecular genetic criteria for predicting the effectiveness of steroid and immunosuppressive therapy for primary nephrotic syndrome in children” No. 200080056.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Игнатова М.А.
