Клещевой энцефалит (КЭ), одна из масштабных проблем здравоохранения Сибирского региона, способна вызвать у человека значительные цитогенетические нарушения за счет стимуляции оксидативного стресса. Активное функцио­нирование системы детоксикации фермента глутатион-S-трансферазы призвано защищать генетические структуры клеток организма, в то же время имеются исследования. свидетельствующие о дефектном функционировании этой системы у лиц с отягощенным ожирением.</p></sec><sec><title>Цель</title><p>Цель. Настоящее исследование проведено с целью изучения длительности сохранения цитогенетических последствий КЭ у лиц, различающихся по аллелям генов ферментов глутатион-S-трансферазы, страдающих алиментарно-конституциональным ожирением в сравнении с контролем.</p></sec><sec><title>Методы</title><p>Методы. Объектом исследования являлись 133 жительницы северных районов Томской области в возрасте от 35 до 44 лет, госпитализированные по поводу инфекции КЭ в местные стационарные медицинские учреждения. Все обследованные были подразделены на две подгруппы. Пациентки 1-й подгруппы (контроль) имели индекс массы тела (ИМТ) в пределах 21–26, 2-я подгруппа имела показатели, свидетельствующие о выраженном ожирении (ИМТ 35–45). Буккальный эпителий для цитогенетического и молекулярного анализа был взят несколько раз: 1–2-й день после госпитализации, через 1 неделю, 1 месяц, 3 месяца и 6 месяцев. Для подтверждения диагноза КЭ были использованы методы иммуноферментного анализа и полимеразной цепной реакции (ПЦР). В качестве интактного контроля проведено обследование 126 здоровых жительниц тех же возрастных групп. Все обследованные подписали добровольное информированное согласие. При анализе делеций в генах GSTM1 и GSTT1 использовали мультиплексную ПЦР. У каждого обследованного изучено не менее 1000 эпителиоцитов.</p></sec><sec><title>Результаты</title><p>Результаты. У пациенток с высокими показателями ИМТ в буккальном эпителии наблюдается увеличение числа клеток с цитогенетическими нарушениями, при этом заболевание КЭ резко увеличивает этот показатель, и цитогенетические изменения сохраняются в организме переболевшей на протяжении полугода. КЭ у пациенток с нормальными весовыми показателями имели значимо меньшие изменения, при этом восстановление цитогенетической нормы наблюдалось через 3 месяца после госпитализации. Анализ вариантов генов фермента глутатион-S-трансферазы показал, что у пациенток, имеющих нормальные весовые показатели, при носительстве неактивных форм генов значимо повышается число эпителиоцитов с микроядрами по сравнению с носительницами генов GSTM1(+)/GSTT1(+). У пациенток с алиментарным ожирением такой закономерности не отмечено.</p></sec><sec><title>Заключение</title><p>Заключение. Цитогенетические изменения у пациенток с ожирением под влиянием КЭ существенно превышают таковые контрольные как по величине, так и по длительности сохранения их в организме. Полиморфизм по генам глутатион-S-трансферазы на этот показатель не оказывал существенного влияния.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Backgraund</title><p>Backgraund. Tick-borne encephalitis (TBE), one of the large-scale public health problems of the Siberian region, can cause significant cytogenetic damage in humans by stimulating oxidative stress. Active functioning of the detoxification system including enzymes of glutathione-S-transferase is intended to protect the genetic structure of cells in the body, while at the same time, there are studies showing the defective functioning of this system in individuals with obesity.</p></sec><sec><title>Aims</title><p>Aims. Aim of this work is to study the longevity of term of TBE-induced cytogenetic damage in patients with different alleles of genes of glutathione-S-transferase, suffering from alimentary-constitutional obesity compared with the control.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We were examined 133 female residents of the northern areas of Tomsk region from 35 to 44 years old who were hospitalized for infection TBE at local medical clinics. All individials were divided into two subgroups. Patients of the 1st subgroup (control) had a body mass index (BMI) within 21–26, the 2nd subgroup had BMI showing severe obesity (BMI 35–45). Buccal cells for cytogenetic and molecular analysis were taken several times: 1–2 days after hospitalization, 1 week, 1 month, 3 months, and 6 months after beginning of the disease. Methods of immunoassay and polymerase chain reaction (PCR) was used to confirm the diagnosis of TBE. As an untreated control were examined 126 healthy female residents of the same age groups. All individuals signed informed consent. In the analysis of deletions in the genes GSTM1 and GSTT1 was used multiplex PCR. We studied at least 1000 epithelial buccal cells from each individual.</p></sec><sec><title>Results</title><p>Results. In patients with high BMI rates revealed a significant increase in the frequency of the buccal cells with cytogenetic damage, compared to the control group. TBE disease was significantly increased the frequency of the cytogenetically damaged cells in this group of patients. The cytogenetic aberrations persisted in their body for six months after hospitalization. In patients with normal BMI rates TBE induced significantly less changes. The recovery of normal cytogenetic status was observed in this group 3 months after hospitalization. Analysis of the glutathione-S-transferase gene variants showed that in TBE patients with normal BMI and non-active alleles of these genesthe frequency of micronucleated epithelial cellswere significantly increased compared to the patients with the activeGSTM1 (+) / GSTT1 (+)genes. In the patients with alimentary obesity such patterns were not observed.</p></sec><sec><title>Conclusions</title><p>Conclusions. Thus,infection with TBE in patients with obesity induced significant increase in both the frequency of cytogenetically damaged cells and the longevity of their persistency in the body compared to these in control group. Polymorphisms in genes of glutathione-S-transferase had no significant effect on the indices.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микроядерный анализ</kwd><kwd>клещевой энцефалит</kwd><kwd>ожирение</kwd><kwd>GSTM1</kwd><kwd>GSTT1</kwd><kwd>глутатион-S-трансфераза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>micronucleus assay</kwd><kwd>tick-borne encephalitis</kwd><kwd>obesity</kwd><kwd>GSTM1</kwd><kwd>GSTT1</kwd><kwd>glutathione-S-transferase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Врачи-инфекционисты стационарных медицинских учреждений северных районов Томской области</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vigneri P, Frasca F, Sciacca L, et al.
