Determination of frequency of occurrence and clinical significance of interleukin-28B (IL28B) and RNAse L gene polymorphism in patients with chronic hepatitis C (CHC). Materials and methods. 104 hospital patients with CHC (65% male; 63% with genotype 1 hepatitis C virus - HCV) were examined. 70 patients received therapy with interferon (IFN) and ribavirin (RBV). Single nucleotide polymorphism (SNP) of IL28B gene 39743165T&gt;G (rs8099917), SNP 39738787C&gt;T (rs12979860) and RNAse L gene (1385G&gt;A) were determined by polymerase chain reaction. Results. The frequency of detection of «favorable» SNP allele variants of IL28B gene in patients with CHC was lower than in population of the European region. In patients with genotype 1 HCV, mutant alleles in SNP 39743165T&gt;G (р=0.045) and 39738787C&gt;T (р=0.005) occurred more frequently than in patients with other virus genotypes. Higher values of alanine aminotransferase in patients with genotype CC 39738787C&gt;T were detected. Frequencies ofSNP variants of IL28B and RNAse L gene did not differ depending on the speed of disease progression (p&gt;0.5). Response to IFN/RBV therapy was higher in «favorable» ТТ (SNP 39743165T&gt;G) and СС (SNP 39738787C&gt;T) variants. Conclusion. Examination for IL28B gene SNP 39738787C&gt;T is recommended before the start of IFN/RBV therapy in all the patients with genotype 1 HCV as a prognostic factor on the therapy response. RNAse L gene SNP 1385G&gt;A does not have a clear clinical significance in CHC.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Определение частоты встречаемости и клинического значения полиморфизмов генов интерлейкина-28B (IL28B) и РНКазы L у пациентов с хроническим гепатитом С (ХГС). Материалы и методы. Обследованы 104 стационарных пациента с ХГС (65% мужчины; 63% с генотипом 1 вируса гепатита С - ВГС). 70 пациентов получали лечение препаратами интерферона (IFN) и рибавири-на (RBV). Методом полимеразной цепной реакции определяли единичные нуклеотидные полиморфизмы (SNP) гена IL28B 39743165T&gt;G (rs8099917), SNP 39738787C&gt;T (rs12979860) и гена РНКазы L (1385G&gt;A). Результаты. Частота встречаемости «благоприятных» аллельных вариантов SNP гена IL28B у пациентов с ХГС была ниже, чем в популяции европейского региона. У пациентов с генотипом 1 ВГС чаще встречаются мутантные аллели в SNP 39743165T&gt;G (р=0,045) и 39738787C&gt;T (р=0,005), чем у больных с иными генотипами вируса. Выявлены более высокие значения аланина-минотрансферазы у пациентов с генотипом СС 39738787C&gt;T Частоты вариантов SNP генов IL28B и РНКазы L не различались в зависимости от скорости прогрессирования заболевания (p&gt;0,5). Ответ на терапию IFN/RBV был выше при «благоприятных» вариантах ТТ (SNP 39743165T&gt;G) и СС (SNP 39738787C&gt;T). Заключение. Обследование на SNP 39738787C&gt;T гена IL28B рекомендуется перед началом терапии IFN/RBV всем пациентам с генотипом 1 ВГС в качестве прогностического фактора ответа на лечение. SNP 1385G&gt;A гена РНКазы L не имеет явного клинического значения при ХГС.</p></trans-abstract><kwd-group xml:lang="en"><kwd>IL28B gene polymorphism</kwd><kwd>RNAse L</kwd><kwd>chronic hepatitis C</kwd><kwd>interferon therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полиморфизм гена IL28B</kwd><kwd>РНКаза L</kwd><kwd>хронический гепатит С</kwd><kwd>интерферонотерапия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Мицура В.М., Воропаев Е.В., Осипкина О.В., Жаворонок С.В.
