Изучение распространённости полиморфных маркеров ABCB1 и прогнозирование клинико-лабораторных и демографических параметров у больных ишемическим инсультом является актуальным направлением фармакогенетики и практической неврологии.</p></sec><sec><title>Цель</title><p>Цель. Определить частоту полиморфизма ABCB1 (C3435T, rs1045642) у больных ишемическим инсультом и оценить его ассоциацию с клинико-лабораторными и демографическими показателями пациентов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследуемую группу вошли 120 пациентов с некардиоэмболическим ишемическим инсультом. Генотипирование полиморфизма ABCB1 (C3435T, rs1045642) выполнено методом полимеразной цепной реакции. Проведён анализ клинико-демографических факторов и частот распределения генотипов ABCB1 (C3435T).</p></sec><sec><title>Результаты</title><p>Результаты. Генотип СС верифицирован у 18,0 %, СТ — у 56,0 %, ТТ — у 26,0 % пациентов. Распределение генотипов по ABCB1 (C3435T, rs1045642) среди больных ишемическим инсультом соответствовало закону Харди-Вайнберга (χ²=1,81; р=0,18). При оценке сопоставимости клинико-демографических характеристик и результатов генотипирования по ABCB1 (C3435T, rs1045642) отмечена статистически значимая разница в частоте выявления сахарного диабета и избыточной массы тела у больных ИИ. Сахарный диабет и ожирение с большей частотой выявлялись в группе пациентов — носителей генотипов СТ+ТТ: при наличии сахарного диабета — 31,6 % против 18,2 % (р=0,023); при наличии избыточной массы тела — 36,7 % против 18,2 % (р=0,003). При оценке сопоставимости средних количественных лабораторных показателей у носителей генотипов СС и СТ+ТТ полиморфизма ABCB1 (C3435T, rs1045642) выявлено, что в общем анализе крови средний уровень лейкоцитов и нейтрофилов статистически значимо был выше в группе пациентов с генотипом СС.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные могут повлиять на выбор приоритетности для внедрения фармакогенетических тестов как при цереброваскулярной патологии, так и при других заболеваниях.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. The study of the prevalence of ABCB1 polymorphic markers and the prediction of clinical, laboratory and demographic parameters in patients with ischemic stroke is a relevant area of pharmacogenetics and practical neurology.Objective. To determine the frequency of ABCB1 polymorphism (C3435T, rs1045642) in patients with ischemic stroke and evaluate its association with clinical, laboratory and demographic parameters of patients.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study group included 120 patients with non-cardioembolic ischemic stroke. Genotyping of ABCB1 polymorphisms (C3435T, rs1045642) was performed by polymerase chain reaction. An analysis of clinical and demographic factors and distribution frequencies of ABCB1 genotypes (C3435T) was performed.</p></sec><sec><title>Results</title><p>Results. The CC genotype was verified in 18.0 %, CT in 56.0 %, and TT in 26.0 % of patients. The distribution of ABCB1 genotypes (C3435T, rs1045642) among patients with ischemic stroke complied with the Hardy-Weinberg law (χ²=1.81; p=0.18). When assessing the comparability of clinical and demographic characteristics and the results of genotyping for ABCB1 (C3435T, rs1045642), a statistically significant difference in the frequency of detection of diabetes mellitus and overweight in patients with ischemic stroke was noted. Diabetes mellitus and obesity were detected with a higher frequency in the group of patients carrying the CT+TT genotypes: in the presence of diabetes mellitus — 31.6 % versus 18.2 % (p=0.023); in the presence of excess body weight — 36.7 % versus 18.2 % (p=0.003). No statistically significant association with the clinical features of the course of ischemic stroke was found. Also, no characteristic differences were found between patients carrying the CT/TT genotypes (those who responded and those who did not respond to antiplatelet therapy with clopidogrel). When assessing the comparability of average quantitative laboratory parameters in carriers of the CC and CT+TT genotypes of the ABCB1 polymorphism (C3435T, rs1045642), it was revealed that in the general blood test, the average level of leukocytes and neutrophils was statistically significantly higher in the group of patients with the CC genotype.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained data may influence the choice of priority for the implementation of pharmacogenetic tests both in cerebrovascular pathology and in other diseases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>фармакогенетика</kwd><kwd>генотип</kwd><kwd>P-гликопротеин</kwd><kwd>ABCB1</kwd><kwd>полиморфизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>pharmacogenetics</kwd><kwd>genotype</kwd><kwd>P-glycoprotein</kwd><kwd>ABCB1</kwd><kwd>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">Ivanyuk A, Livio F, Biollaz J, Buclin T.
