Summary: | To assess the risk of insufficient response or adverse reactions to standard doses of anti-TB drugs, it was proposed to use pharmacogenetic testing of genes of enzymes that metabolize these drugs. Since the frequency of genotypes varies depending on patients’ ethnicity, it is necessary to conduct studies among ethnic groups. The aim of this study was to identify the types of N-acetyltransferase 2 (NAT2) polymorphisms and phenotypes and their prevalence among Yakutian tuberculosis patients, as well as to conduct a comparative analysis with Russian patients. In total 158 patients were examined using real-time PCR: 50 – Yakutians, 41 – Russians (Yakutia), 67 – Russians (Moscow region). Six NAT2 polymorphisms were identified (*5, *6, *7, *11, *12, *13). Significant differences in the distribution of NAT2*5, *11, *12 between Yakutians and Russians were found: these polymorphisms prevail among Russian patients. The frequency of rapid phenotype among Yakutians is higher compared to Russians. The data obtained can contribute to the improvement of the antituberculosis therapy effectiveness in Yakutian patients. Для выявления пациентов с риском неэффективности или нежелательных реакций на стандартные дозы противотуберкулёзных препаратов было предложено использование фармакогенетические исследования генов ферментов, метаболизирующих данные лекарственные средства. Так как частота генотипов варьируется в зависимости от этнической принадлежности пациентов, необходимо проведение исследований среди различных этнических групп. Целью данного исследования было выявить типы и распространённость полиморфизмов и фенотипов изониазид-метаболизирующего фермента NAT2 среди якутов, болеющих туберкулёзом, а также провести сравнительный анализ с русскими пациентами. Всего было прогенотипировано 158 пациентов: 50 были якутами, 41 – русскими, проживающими на территории Якутии, 67 – русскими, проживающими на территории Московской области. Было идентифицировано 6 полиморфизмов NAT2 (*5, *6, *7, *11, *12, *13). Обнаружены значимые отличия в ... |
