Оценить концентрацию фактора некроза опухоли-альфа (tumor necrosis factor, TNF-α), интерлейкина-6 (interleukin, IL-6), васкулоэндотелиального фактора роста (vascular endothelial growth factor, VEGF) в сыворотке крови и провести анализ полиморфизма генов цитокинов TNF-α в регионе 308G/A (rs1800629), IL-6 в регионе 174G/С (rs1800795) и VEGF в регионе 634G/C (rs2010963) у пациентов с хроническими диффузными заболеваниями печени (ХДЗП), проживающих в Пермском крае. Материалы и методы. У 193 пациентов с ХДЗП и 90 здоровых доноров исследована концентрация цитокинов в сыворотке крови методом ИФА и выполнен анализ полиморфизма генов цитокинов методом ПЦР. Результаты. У пациентов с ХДЗП концентрация провоспалительных цитокинов TNF-α, IL-6 и уровень VEGF в сыворотке крови были значимо выше, чем в контроле (p&lt;0,001соответственно), при этом максимальный уровень маркеров воспаления отмечен при циррозе печени, а выработка VEGF - при хроническом гепатите С. Сравнительный анализ однонуклеотидных полиморфизмов генов цитокинов показал достоверные различия по встречаемости генотипов GA и АА гена TNF-α (G-308A), носительству варианта СG гена IL-6 (С-174G), а так же по аллелю С и гомозиготе СС для маркера VEGF (G-634C), которые в популяции больных ХДЗП в Пермском крае регистрировались значимо чаще, чем в когорте доноров/ Заключение. Повышение концентрации патогенетически значимых цитокинов TNF-α, IL-6 и VEGF при заболеваниях печени может развиваться на фоне полиморфизмов генов этих молекул. Генетические маркеры можно использовать для оценки риска развития и прогрессирования ХДЗП.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To estimate the concentration of tumor necrosis factor-alpha (TNF-α), interleukin-6 (interleukin, IL-6), vascular endothelial growth factor (VEGF) in blood serum and to analyze the polymorphism of TNF-α cytokine genes in region 308G / A (rs1800629), IL-6 in region 174G / C (rs1800795) and VEGFA in region 634G / C (rs2010963) in patients with chronic diffuse liver diseases (CDLD) living in the Perm region. Materials and methods. In 193 patients with CDLD and 90 healthy donors, the concentration of cytokines in the blood serum was studied by ELISA and the analysis of cytokine gene polymorphism by PCR was performed. Results. In patients with CDLD, the concentration of pro-inflammatory cytokines TNF-α, IL-6 and the level of VEGF in the blood serum were significantly higher than in the control (p &lt;0.001, respectively), while the maximum level of inflammation markers was noted in liver cirrhosis, and VEGF production - in chronic hepatitis C. Comparative analysis of single nucleotide polymorphisms of cytokine genes showed significant differences in the occurrence of the GA and AA genotypes of the TNF-α gene (G-308A), the carriage of the CG variant of the IL-6 gene (C-174G), as well as the C allele and CC homozygote for marker VEGF (G-634C), which in the population of patients with CDLD in the Perm region were recorded significantly more often than in the cohort of donors, which allows us to consider them as genetic markers of the risk of developing CDLD. Conclusion. An increase in the concentration of pathogenetically significant cytokines TNF-α, IL-6 and VEGF in liver diseases can develop against the background of gene polymorphisms of these molecules. Genetic markers can be used to assess the risk of developing and progression of CDLD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронические диффузные заболевания печени</kwd><kwd>фактор некроза опухоли-α</kwd><kwd>интерлейкин-6</kwd><kwd>васкулоэндотелиальный фактор роста</kwd><kwd>полиморфизм генов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic diffuse liver diseases</kwd><kwd>tumor necrosis factor-α</kwd><kwd>interleukin-6</kwd><kwd>vasculoendothelial growth factor</kwd><kwd>gene polymorphism</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">Kuz’mina Yu.S., Zhmurov V.
