Гомоцистеин (Hcy) является аминокислотой, участвующей в формировании атеросклеротических изменений в стенке артерий и способствующей прогрессирующему течению заболеваний артерий нижних конечностей. Полиморфизмы C677T, A1298C гена метилентетрагидрофолат редуктазы (MTHFR), A2756G гена метионинсинтазы (MTR) и A66G гена метионинсинтазы-редуктазы (MTRR), участвующие в обмене Нсу, являются наиболее функционально значимыми.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: анализ распределения генетических маркёров A1298C MTHFR, C677T MTHFR, A2756G MTR, A66G MTRR у пациентов с ЗАНК и оценка их влияния на исходы реваскуляризирующих операций при поражении аорто-подвздошно-бедренного сегмента (АПБС).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены 60 пациентов с изолированным, либо сочетанным поражением АПБС и бедренно-подколенно-берцового сегмента. Возраст исследуемых составил 61,5 [59; 66] лет.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. После генотипирования полиморфизмов установлено, что наиболее распространёнными аллелями для исследуемых генетическим маркёров были следующие: для A1298C MTHFR гомозиготный АА – 29 пациентов, для C677T MTHFR гетерозиготный CT – 36, для A2756G MTR гетерозиготный аллель AG – 33, для A66G MTRR гетерозиготный аллель AG – 26. В исследуемой группе пациентов была установлена гипергомоцистеинемия – 19,3 [13,9; 23,1] мкмоль/л. Срок наблюдения за пациентами составил 16 [12; 20] месяцев. За данный период наблюдения было выявлено 12 осложнений. Наиболее мощными предикторами оказались наличие гетерозиготного аллеля СТ C677T, Cys, GSH. Используя данные предикторы, была построена прогностическая модель с чувствительностью 83,33%, специфичностью 81,25% и точностью 81,67%.</p></sec><sec><title>Выводы</title><p>Выводы. Среди пациентов с окклюзионно-стенотическим поражением АПБС большинство оказались носителями гетерозиготных аллелей исследуемых генетических маркёров C677T MTHFR, A2756G MTR, A66G MTRR, для A1298C MTHFR – гомозиготного аллеля АА (n = 29).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Homocysteine (Hcy) is an amino acid involved in the formation of atherosclerotic chan­ ges in the arterial wall and contributes to the progressive course of lower extremity arterial disease. Polymorphisms C677T, A1298C of the methylenetetrahydrofolate reductase (MTHFR) gene, A2756G of the methionine synthase (MTR) gene, and A66G of the methionine synthase reductase (MTRR) gene involved in Hcy metabolism are the most functionally significant.</p><p>The aim of the study was to analyze the distribution of genetic markers A1298C MTHFR, C677T MTHFR, A2756G MTR, A66G MTRR in patients with LEAD and assess their impact on the outcomes of revascularization surgeries for lesions of the aorto­ilio­femoral segment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 60 patients with isolated or combined lesions of aorto­ ilio­femoral and the femoral­popliteal­tibial segments. The age of the subjects was 61.5 [59; 66] years.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. After genotyping of polymorphisms, it was found that the most common alleles for the studied genetic markers were the following: for A1298C MTHFR homozygous AA – 29 patients, for C677T MTHFR heterozygous CT – 36, for A2756G MTR heterozygous allele AG – 33, for A66G MTRR heterozygous allele AG – 26. Hyperhomocysteinemia was established in the study group of pa­ tients – 19.3 [13.9; 23.1] µmol/l. The follow­up period for patients was 16 [12; 20] months. During this observation period, 12 complications were identified. The most powerful predictors were the presence of the heterozygous CT allele C677T, Cys, GSH. Using these predictors, a prognostic model was deve­ loped with a sensitivity of 83.33%, a specificity of 81.25%, and an accuracy of 81.67%.</p></sec><sec><title>Conclusions</title><p>Conclusions. Most of the patients with occlusive­stenotic lesions of aorto­ilio­femoral segment were carriers of heterozygous alleles of the studied genetic markers C677T MTHFR, A2756G MTR, A66G MTRR, for A1298C MTHFR – the homozygous AA allele (n = 29).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>заболевания артерий нижних конечностей</kwd><kwd>реваскуляризация</kwd><kwd>генетический полиморфизм</kwd><kwd>аминокислоты</kwd><kwd>послеоперационные осложнения</kwd><kwd>гомоцистеин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lower extremity arterial disease</kwd><kwd>revascularization</kwd><kwd>genetic polymorphism</kwd><kwd>amino acids</kwd><kwd>postoperative complications</kwd><kwd>homocysteine</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">Горохова, В.Г.
