Примерно у 50% пациентов с нефротическим синдромом формируется зависимость от стероидной терапии, что требует включения схемы лечения селективной иммуносупрессивной терапии. Одним из перспективных препаратов стероидзависимого нефротического синдрома признана микофеноловая кислота, которая в настоящее время служит основой иммуносупрессивной терапии синдрома. В приведенном исследовании оценивается значение определения экспрессии генов, отвечающих за метаболизм микофеноловой кислоты, у пациентов со стероидзависимым нефротическим синдромом для поддержания стойкой клинико-лабораторной ремиссии заболевания. Продемонстрированы клиническая значимость и роль экспрессии генов MDR1, UGT1A7, UGT1A9 и UGT2B7 как потенциальных маркеров повышенного риска рецидивов. Это открывает перспективы применения транскриптомного подхода для выявления пациентов, нуждающихся в осторожном подборе фармакотерапии. Несмотря на полученные результаты, изменения в экспрессии метаболических ферментов представляют собой важный, но не единственный фактор эффективности терапии. На основе этих данных в будущем станет возможным разрабатывать стратегии мониторинга, направленные на индивидуализацию лечения и повышение его эффективности.</p></abstract><trans-abstract xml:lang="en"><p>Nephrotic syndrome is one of the most common glomerular diseases in childhood. It is known that about half of patients with nephrotic syndrome develop dependence on steroid therapy, which requires the inclusion of a treatment regimen of selective immunosuppressive therapy. Mycophenolic acid (MPA) has been identified as a promising drug for steroid-resistant nephrotic syndrome, and it forms the basis of immunosuppressive therapy for this condition. The present study evaluates the importance of determining the expression of genes responsible for the metabolism of mycophenolic acid in patients with steroid-dependent nephrotic syndrome to maintain stable clinical and laboratory remission of the disease. The article demonstrates the significance and role of MDR1, UGT1A7, UGT1A9 and UGT2B7 gene expression as potential markers of increased risk of relapses and opens up prospects for the use of a transcriptomic approach to identify patients who require careful selection of pharmacotherapy. Although the results obtained are promising, changes in the expression of metabolic enzymes are only one of several factors that contribute to the effectiveness of treatment. Based on these data, it may be possible in the future to develop personalized monitoring strategies that can help tailor treatment to individual patients and increase its effectiveness.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>нефротический синдром</kwd><kwd>микофеноловая кислота</kwd><kwd>MDR1</kwd><kwd>UGT</kwd><kwd>экспрессия</kwd><kwd>персонализированная медицина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>nephrotic syndrome</kwd><kwd>mycophenolic acid</kwd><kwd>MDR1</kwd><kwd>UGT</kwd><kwd>expression</kwd><kwd>personalized medicine</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">Pal A., Kaskel F.
