Больные были распределены на 3 группы. В первую вошли дети с хроническим вторичным пиелонефритом и ПМР без рентгенологических и ультразвуковых признаков нефросклероза. 2-ю группу составили пациенты с эхографическими признаками рефлюкс-нефропатии. В 3-ю группу были объединены дети с рентгенологическими проявлениями нефросклероза. Пациенты с хроническим пиелонефритом без нарушения уродинамики составили группу сравнения. В результате у всех больных отмечалось значительное повышение экскреции с мочой ИЛ-8, ИЛ-10 и ФНО-α по сравнению контролем (p &lt; 0,05) и умеренное нарастание концентрации ИЛ-8 и ФНО-α в суточной моче через 6 месяцев после первого исследования, независимо от наличия или отсутствия эхографических и рентгенологических признаков формирования РН. При этом у больных с рентгенологическими и ультразвуковыми признаками РН отмечалось однотипное достоверное (p &lt; 0,05) снижение концентрации ИЛ-10 в суточной моче, в то время как у пациентов 1-й группы экскреция его значительно возрастала. Таким образом, однонаправленное выраженное снижение суточной экскреции с мочой противовоспалительного ИЛ-10 у больных 2-й и 3-й групп при отсутствии существенных изменений ИЛ-8 и повышении содержания в моче ФНО-α у детей с эхографическими признаками поражения почек может свидетельствовать о формировании очагов инфильтрации в почечной паренхиме с последующим склерозированием и может быть использовано в качестве раннего диагностического критерия развития рефлюкс-нефропатии при пузырно-мочеточниковом рефлюксе.</p></abstract><trans-abstract xml:lang="en"><p>In order to reveal the role of pro- and anti-inflammatory cytokines in formation of renal scar in children with chronic pyelonephritis (CP) and vesico-ureteral reflux (VUR) 123 patients with impaired urodynamics aged from 3 to 14 years were examined at the beginning of the study and after 6 months follow-up. In all of them the 24 hours urine excretion of interleukins 8, 10 (IL-8, 10) and tumor necrosis factor-α (TNF-α) has been measured by immunoenzime method. All the children underwent color Doppler ultrasound (CDUS) examination of kidneys. Three groups of patients were determined: 1) with VUR and normal X-ray and ultrasound pictures of kidneys (n = 94); 2) with CDUS detected reflux nephropathy (RN) (n = 12); 3) with IVU confirmed reflux nephropathy (n = 17). Patients with CP without VUR (n = 10) were used as a control. As a result, all the patients demonstrated significantly elevated daily urine excretion of IL-8, IL-10 and TNF-α in comparison with control (p &lt; 0,05) at first investigation and mild increasing of IL-8 and TNF-α concentration after 6 months of follow-up. In children without X-ray and ultrasound signs of renal scarring IL-10 urine concentration increased approximately in 1,2 times. In opposite, representatives of 2 and 3 groups showed identical cutback of IL-10 level in 24 hours urine within 6 months after first investigation. To conclude, the similar dynamics of IL-10 urine level in patients with X-ray confirmed RN and CDUS sings of renal scar formation suggests that IL-10 can be used as an early marker of renal tissue damage. The diminishing of anti-inflammatory cytokine may reflect the protraction of covered inflammation in renal parenchyma in remission of CP.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рефлюкс-нефропатия</kwd><kwd>интерлейкины 8</kwd><kwd>10</kwd><kwd>фактор некроза опухоли α</kwd><kwd>ангиотензин II</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">Игнатова М.С., Вельтищев Ю.Е.
