Целью работы явилось изучение уровня в сыворотке крови двух цитокинов - фактора некроза опухоли β (TNF-β) и инсулиноподобного фактора роста-1(IGF-1) у 46 детей с различными вариантами и разной степенью активности хронического пиелонефрита. 13 детей (1 группа) страдали острым пиелонефритом, 7 (2 группа) - обострением хронического пиелонефрита; у 12 (3 группа) детей имел место пузырно-мочеточниковый рефлюкс (ПМР), осложненный хроническим пиелонефритом в стадии ремиссии, у 14 (4 группа) - первичный необструктивный пиелонефрит вне обострения. TNF-β и IGF-1 в сыворотке крови определялись иммуноферментным методом с использованием DRG IGF-1 ELSA KIT и R&amp;D TNF-β KIT. Уровень обоих цитокинов в крови оказался наиболее высоким в 3 группе больных, страдавших ПМР. Содержание TNF-b у этих больных составило 131,6 ± 4,7 pg/ml и было значимо выше, чем в трех других группах. Концентрация IGF-1 при остром пиелонефрите оказалось статистически значимо ниже (109,2 ± 3,1 pg/ml), чем во всех группах. Полученные данные позволяют полагать, что повышение содержания цитокинов в крови детей, страдающих ПМР, может отражать значение нарушений уродинамики в механизме обструктивных нефропатий, а также участие аутоиммунного компонента в воспалительном процессе в почечной паренхиме. Выявленные изменения можно также рассматривать как признак интерстициального фиброза почечной паренхимы.</p></abstract><trans-abstract xml:lang="en"><p>Cytokines are considered to be the key factors in the mechanisms resposible for the different pathological processes. We investigated the blood level of two cytocines (TNF-β and IGF-1) in 45 children with chronic pyelonephritis. All the children were divided into four groups. The first group consisted of 13 children with acute pyelonephritis. The second group consisted of 7 children with an exacerbation of chronic pyelonephritis. The third group consisted of 13 patients with vesicoureteric reflux without any symptoms of active urinary tract infection. The patients of the fourth group (14 children) had the chronic non-obstructive pyelonephritis. The blood level of TNF-β and IGF-1 was estimated by means of DRG IGF-1 ELSA KIT and R&amp;D TNF-β KIT. The blood level of both cytokines was the highest in the third group. It reached 131, 6 ± 4,7 pg/ml in this group and was significantly higher than in three others groups (p &lt; 0,05). The IGF-1 blood level was the lowest in the first group. We suppose that the increase in TNF-β and IGF-1 blood level in children with vesicoureteric reflux may be connected mechanisms responsible for reflux nephropathy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фактор некроза опухоли β ( TNF-β)</kwd><kwd>инсулиноподобный фактор роста-1 (IGF-1)</kwd><kwd>хронический пиелонефрит</kwd><kwd>пузырно-мочеточниковый рефлюкс</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">Панаян А., Савенкова Н.
