Studied parameters in the synovial fluid were much higher than the serum level. With the development of uveitis TIMP-1 in blood serum was lower than in the absence of eye damage. On treatment of patients significant changes in the studied enzymes weren’t established. On a good response to therapy the level of MMP-9 in serum decreased, on the lack of effectiveness – increased. <bold>Conclusions</bold></italic><bold><italic>.</italic></bold><italic> The analysis results confirm the involvement of MMP-2, MMP-9 and TIMP-1 in the processes of inflammatory changes of the joints in juvenile idiopathic arthritis (JIA) and reactive arthritis, regardless the patients’sex or age.</italic></p><p> </p></abstract><trans-abstract xml:lang="ru"><p><italic>Одним из перспективных направлений современной ревматологии является изучение системы матриксных металлопротеиназ (ММП) при ювенильных артритах — ферментов, играющих ключевую роль в процессах суставной деструкции. <bold>Цель</bold>: оценить содержание ММП-2 и ММП-9 и их тканевого ингибитора (ТИМП-1) в сыворотке крови и синовиальной жидкости при различных вариантах ювенильного артрита у детей. <bold>Пациенты и методы</bold>. В исследовании приняли участие 82 ребенка с ювенильными артритам и 20 здоровых детей. Уровень ММП-2, ММП-9 и ТИМП-1 определяли в сыворотке крови и синовиальной жидкости методом ИФА. <bold>Результаты</bold>. Установлено, что при любой форме артрита сывороточная концентрация ММП-2, ММП-9 и ТИМП-1 достоверно превышала контрольные значения, однако уровень ММП-2 в подгруппе артрита, ассоциированного с энтезитом, не отличался от контрольного. Изучаемые показатели в синовиальной жидкости значительно превышали сывороточный уровень. При развитии увеитов ТИМП-1 в сыворотке крови был ниже, чем при отсутствии поражения глаз. В процессе лечения пациентов достоверных изменений изучаемых ферментов установлено не было. При хорошем ответе на терапию уровень ММП-9 в сыворотке крови снижался, при недостаточной эффективности повышался. <bold>Выводы</bold>. Полученные данные подтверждают участие ММП-2, ММП-9 и ТИМП-1 в процессах воспалительных изменений суставов при ЮИА и реактивном артрите, независимо от пола и возраста пациентов.</italic></p><p> </p></trans-abstract><kwd-group xml:lang="en"><kwd>juvenile idiopathic arthritis</kwd><kwd>reactive arthritis</kwd><kwd>matrix metalloproteinase-2</kwd><kwd>matrix metalloproteinase-9</kwd><kwd>tissue inhibitor of metalloproteinases-1</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>ювенильный идиопатический артрит</kwd><kwd>реактивный артрит</kwd><kwd>матриксная металлопротеиназа-2 и-9</kwd><kwd>тканевой ингибитор матриксных металлопротеиназ-1</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
