С целью изучения данной проблемы был исследован сывороточный и локальный профиль регуляторов ремоделирования ткани печени при HCV-ассоциированном фиброзе печени по уровню матриксной металлопротеиназы-9 (MMP-9), тканевого ингибитора матриксной металлопротеиназы-1 (TIМP-1), комплексов MMP-9/TIMP-1 и MMP-9/ TIMP-2. Проведено комплексное клинико-лабораторное и инструментальное обследование 81 пациента с ХГС, которые не получали противовирусную терапию (ПВТ), и 22 практически здоровых добровольцев. Изучены показатели белков внеклеточного матрикса (ВКМ) в 103 образцах сыворотки крови и 32 супернатантах гепатобиоптатов методом твердофазного иммуноферментного анализа (ИФА). Отмечено статистически значимое повышение содержания ММP-9 (р &lt; 0,05) и ее комплексов с ТIМP-1 (р &lt; 0,05) и ТIМP-2 (р &lt; 0,01) в сочетании с низким показателем ингибитора первого типа (р &lt; 0,05) в сыворотке крови HCV-инфицированных пациентов относительно контрольной группы. Анализ содержания белков, отражающих состояние межклеточного матрикса, в супернатантах гепатобиоптатов у пациентов ХГС выявил восьмикратное увеличение уровня комплекса ММP-9/ТIМP-1 в сравнении с группой контроля (р &lt; 0,05), при этом значения других представителей семейства протеолиз/антипротеолиз оказались низкими (р &lt; 0,05). Обнаружен дисбаланс содержания протеиназ в сыворотке крови и супернатантах гепатобиоптатов, который имел различную направленность изменений, а именно – сывороточные значения ММP-9, ТIМP-1 и ММP-9/ ТIМP-2 по мере трансформации фиброза печени в цирроз (от F0 ст. к F4 ст.) снижались (р &lt; 0,05), но при этом концентрация указанных протеолитических ферментов в органе-мишени повышалась (р &lt; 0,05). Обобщая вышесказанное, можно заключить, что полученные нами данные в результате исследования свидетельствуют о том, что нарушение равновесия системы «протеолиз/антипротеолиз» приводит к дисрегуляции ремоделирования ткани печени при ХГС.</p></abstract><trans-abstract xml:lang="en"><p>Imbalance of the proteolysis/antiproteolysis system is known to be among key components of immunofibrogenesis of liver in cases of chronic hepatitis C. To evaluate these aspects, we studied several factors of liver tissue remodeling in blood serum and local samples from HCV patients associated with liver fibrosis. We determined the levels of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1), MMP-9/TIMP-1 and MMP-9/TIMP-2 complexes. Clinical, laboratory and instrumental examinations have been made for 81 patients with chronic hepatitis C who did not receive antiviral therapy, and 22 healthy volunteers. Extracellular matrix protein (ECM) profile was studied in 103 serum blood samples and 32 liver supernates using ELISA technique. Statistically significant increase of MMP-9 contents (p &lt; 0.05) and its complexes with TIMP-1 (p &lt; 0.05) and TIMP-2 (p &lt; 0.01), as well as low levels of type 1 inhibitor (p &lt; 0.05) were revealed in blood serum of HCV-infected patients, as compared with control group. Protein assays in liver supernates of hepatitis C patients reflecting extracellular matrix state revealed an eight-fold increase in MMP-9/ TIMP-1 complex, as compared with control group (p &lt; 0.05). The values of other proteolytic/antiproteolytic factors proved to be low (p &lt; 0.05). An imbalance in protease contents in blood serum and liver biopsies was revealed, showing differently directed changes. I.e., serum values of MMP-9, TIMP-1 and MMP-9/TIMP-2 during transition of liver fibrosis to cirrhosis (F0 to F4) became decreased (p &lt; 0.05), associated with increased liver concentrations of these proteolytic enzymes (p &lt; 0.05). In summary, we conclude that the data obtained in our study suggest an imbalance of proteolysis/antiproteolysis system leads to a dysregulated liver tissue remodeling in patients with chronic hepatitis C.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>матриксная металлопротеиназа</kwd><kwd>тканевой ингибитор матриксной металлопротеиназы</kwd><kwd>хронический гепатит С</kwd><kwd>фиброз печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>matrix metalloproteinase</kwd><kwd>tissue inhibitor of matrix metalloproteinase</kwd><kwd>chronic hepatitis C</kwd><kwd>liver fibrosis</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">Бабак О.Я., Колесникова Е.В., Кравченко Н.А.
