Ввиду прогрессирующего течения гемолитико-уремического синдрома, вплоть до терминальной стадии почечной недостаточности необходим поиск ранних маркеров повреждения почечной ткани как прогностически значимых факторов развития нефросклероза. Это имеет особое значение в детском возрасте для оптимизации ведения таких пациентов. Анализ данных литературы демонстрирует актуальную роль серотонина и его тромбоцитарно-опосредованного влияния на фиброзно-воспалительные процессы в сосудах почек. Таким образом, в дебюте гемолитико-уремического синдрома имеются изменения в серотонинергической системе. Это дает основания для разработки новых диагностических подходов с целью ранней диагностики и замедления прогрессирования повреждения почек. Полученные данные позволят расширить знания о роли серотонинергической системы при формировании хронической болезни почек у детей с гемолитико-уремическим синдромом. </p></abstract><trans-abstract xml:lang="en"><p>Hemolytic-uremic syndrome includes a triad of symptoms: microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Given the progressive course of hemolytic-uremic syndrome, up to the terminal stage of renal failure, it is necessary to search for early markers of renal tissue damage as prognostically significant factors in the development of nephrosclerosis, which is of particular importance in childhood to optimize the management of such patients. The analysis of the literature data demonstrates the actual role of serotonin and platelet-mediated effect of serotonin on fibroinflammatory processes in kidney vessels. Thus, changes in the serotonergic system in patients already at the onset of hemolytic-uremic syndrome are of great interest in order to develop new diagnostic approaches that allow optimizing early diagnosis and slowing down the progression of renal damage in this category of patients. These studies will expand knowledge about the role of the serotonergic system in the formation of chronic kidney disease in children with hemolytic-uremic syndrome. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>гемолитико-уремический синдром</kwd><kwd>хроническая болезнь почек</kwd><kwd>серотонин</kwd><kwd>5-ГИУК</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>hemolytic-uremic syndrome</kwd><kwd>chronic kidney disease</kwd><kwd>serotonin</kwd><kwd>5-HIAA</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">Yoshida Y., Kato H., Ikeda Y., Nangaku M.
