У больных хроническим миелолейкозом (ХМЛ) в зависимости от наличия или отсутствия мутаций в гене ВСR-АВL, а также от типа мутаций, наблюдается различный терапевтический эффект при лечении ингибиторами тирозинкиназ (ИТК).</p></sec><sec><title>Цель работы</title><p>Цель работы: установить прогностическое значение полиморфных вариантов генов, участвующих в метаболизме ИТК: CYP3A5 и hOCT1 у больных ХМЛ в республике Башкортостан (РБ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Генетические исследования проведены у 114 больных с клинически и цитогенетически установленным диагнозом хронического миелолейкоза (ХМЛ). Мужчин было 55, женщин 59, медиана возраста составила 43 года (от 14 до 76 лет). Все больные получали лечение ИТК согласно национальным клиническим рекомендациям и критериям European Leukemia Net. Для сравнения больных с различной эффективностью лечения была сформирована группа из 64 больных, резистентных к проводимой терапии. Сравниваемые группы были сопоставимы по полу и возрасту. Анализ полиморфных ДНК-локусов генов hOCT1 и CYP3A5 осуществляли методом полимеразной цепной реакции синтеза ДНК и ПДРФ-анализом с последующим электрофорезом в 7–8 % полиакриламидном геле.</p></sec><sec><title>Результаты</title><p>Результаты. Не было обнаружено выраженных различий в распределении частот аллелей и генотипов полиморфного локуса rs776746 гена изофермента P3A5 цитохрома p450 (CYP3A5) (p &gt; 0,05) между больными ХМЛ, у которых была разная эффективность лечения ИТК. При сравнении распределения частот аллелей и генотипов полиморфного варианта rs683369 в гене переносчике органических катионов (hOCT1) обнаружено, что генотип *C*C статистически значимо чаще выявлялся у больных с оптимальным ответом на лечение по сравнению с больными, резистентными к лечению. Частота встречаемости генотипа *С*G была почти в два раза выше у больных ХМЛ, резистентных к терапии, — 42,86 %, по сравнению с группой больных с оптимальным ответом на лечение ИТК — 21,88 %.</p></sec><sec><title>Заключение</title><p>Заключение. У больных ХМЛ исследование полиморфного локуса rs683369 гена hOCT1 в отличие от rs776746 гена CYP3A5 имеет прогностическое значение в оценке эффективности лечения ИТК. Частота встречаемости генотипа *С*G была значимо выше у больных ХМЛ, резистентных к терапии ИТК, генотип G*G* встречался реже и был ассоциирован с наименьшей продолжительностью жизни, а наличие генотипа С*С* оказалось благоприятным для общей выживаемости больных.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Patients suffering from chronic myeloid leukemia (CML) demonstrate various degrees of therapeutic effect after treatment using tyrosine kinase inhibitors (TKI). The response is determined by the presence or absence of mutations in the BCR-ABL gene, as well as by the mutation type.</p></sec><sec><title>Aim</title><p>Aim. To establish the prognostic value of polymorphic variants of genes involved in the metabolism of TKI — CYP3A5 and hOCT1 — in patients with CML in the Republic of Bashkortostan (RB).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A series of genetic studies was performed in 114 patients with a clinically and cytogenetically established diagnosis of chronic myeloleukemia (CML), among whom 55 and 59 were men and women, respectively, with the median age of 43 years, from 14 to 76 years. All the patients received TKI treatment according to national clinical guidelines and European Leukemia Net criteria. In order to compare patients with different treatment efficiencies, a group of 64 patients resistant to the therapy was formed. The groups under comparison were similar in gender and age. An analysis of polymorphic DNA loci of the hOCT1 and CYP3A5 genes was carried out using polymerase chain reaction of DNA synthesis and RFLP analysis followed by electrophoresis in 7–8 % polyacrylamide gel.</p></sec><sec><title>Results</title><p>Results. No significant differences were found in the frequency distribution of alleles and genotypes of the rs776746 polymorphic locus of the isoenzyme P3A5 cytochrome p450 (CYP3A5) gene (p &gt; 0.05) between CML patients with different TKI treatment efficiencies. When comparing the frequency distribution of alleles and genotypes of the rs683369 polymorphic variant in the (hOCT1) organic cation carrier gene, the *C*C genotype was established to be statistically significantly more frequent in patients with an optimal response to treatment compared to those treatment resistant. The frequency of occurrence of the *С*G genotype was almost two times higher in CML patients resistant to therapy and comprised 42.86 %, compared to the group of patients with an optimal response to TKI treatment with the value of 21.88 %.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический миелолейкоз</kwd><kwd>эпидемиология</kwd><kwd>мутации</kwd><kwd>полиморфизм генов CYP3A5 и hOCT1</kwd><kwd>ингибиторы тирозинкиназ</kwd><kwd>резистентность</kwd><kwd>прогноз</kwd><kwd>выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic myeloleukemia</kwd><kwd>epidemiology</kwd><kwd>mutations</kwd><kwd>CYP3A5 and hOCT1 gene polymorphism</kwd><kwd>tyrosine kinase inhibitors</kwd><kwd>resistance</kwd><kwd>prognosis</kwd><kwd>survival</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Источник финансирования.
