Для оценки прогноза хронической болезни почек и своевременного применения превентивных терапевтических возможностей крайне важной задачей являются установление скорости прогрессирования нефропатий и выявление ранних клинических маркеров развития нефроскероза. ЦЕЛЬ: установление закономерностей достижения ХБП С3 стадии у детей с нефропатиями иммунного и неиммунного генеза. ПАЦИЕНТЫ И МЕТОДЫ. В проведенном ретроспективном анализе историй болезни 145 детей с ХБП иммунного (стероидрезистентный нефротический синдром, n=75) и неиммунного генеза (наследственный нефрит, поликистоз почек, рефлюкс-нефропатия, врожденные аномалии почек, n=70) была проанализирована динамика СКФ методом Каплана-Мейера от момента дебюта болезни до возраста достижения ХБП С3 стадии. РЕЗУЛЬТАТЫ. Установлены сроки достижения ХБП С3 стадии в зависимости от степени выраженности протеинурии и артериальной гипертензии. Продемонстрировано, что при достижении ремиссии стероидрезистентного нефротического синдрома в условиях селективной иммуносупрессивной терапии в 100% случаев отсутствовало прогрессирование болезни более 5 лет. При изучении темпов прогрессирования у пациентов с гетерогенной группой неиммунных нефропатий установлено, что наименьший период до снижения СКФ ниже 60 мл/ мин (5 лет) отмечен у пациентов при наличии артериальной гипертензии II степени в условиях как минимальной (менее 1 г/сут), так и умеренной (1-2 г/сут) протеинурии. ЗАКЛЮЧЕНИЕ. Таким образом, возможность оценить темпы развития неблагоприятных исходов ХБП в детском возрасте способствует оптимизации терапевтической тактики и значимо влияет на замедление скорости снижения функций почек.</p></abstract><trans-abstract xml:lang="en"><p>RELEVANCE. Determination of nephropathy progression rate and reveal of early nephrosclerosis development clinical markers are extremely important for evaluation of chronic kidney disease prognosis and use of preventive therapeutic possibilities. THE AIM: to define regularities of progression to the CKD 3 stage in children with immune and non-immune nephropathies. PATIENTS AND METHODS. Due to retrospective analysis of 145 cases of children with immune CKD (steroid resistant nephrotic syndrome, n=75) and non-immune CKD (congenital nephritis, reflux-nephropathy, cystic disease, congenital kidney abnormalities, n=70) GFR dynamics was analyzed by Kaplan-Meier method from the onset of disease till age of CKD 3 stage. RESULTS. Established period for achievement CKD 3 stage depends on degree of proteinuria and arterial hypertension. Efficacy of selective inmmusupresive therapy in SRNS provides no 5-years GFR decline in 100% cases. In patients with non-immune nephropathies the highest rate of progression (to GFR lower 60 ml/min) was found in children with 2 stage arterial hypertension combined with low (less than 1 g/days), and moderated (1-2 g/days) proteinuria. CONCLUSION. Therefore, possibility of adverse outcomes progression rate evaluation in children with CKD promotes the optimization of therapeutic tactics and significantly influences on delay of kidney functions declining.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ХБП</kwd><kwd>скорость прогрессирования</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CKD</kwd><kwd>progression rate</kwd><kwd>children</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">Смирнов А.В., Шилов Е.М., Добронравов В.А., Каюков А.Г. и др.
