Эффективность программ экстракорпорального оплодотворения (ЭКО) остаётся ограниченной, что обусловливает необходимость поиска новых прогностических маркеров. Ген CYP2A6 экспрессируется в эстроген-чувствительных тканях, а его активность регулируется половыми стероидами, однако вклад его полиморфизмов в исходы ЭКО остаётся малоизученным.</p></sec><sec><title>Цель</title><p>Цель. Определить взаимосвязь полиморфных вариантов гена CYP2A6 с исходами ЭКО у пациенток, с трубноперитонеальным бесплодием.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В проспективное пилотное исследование включены 96 женщин (средний возраст 31,4±3,7 года) с трубно-перитонеальным бесплодием. Все участницы получали терапию по короткому протоколу с антагонистами гонадотропин-рилизинг-гормона и рекомбинантным фолликулостимулирующим гормоном. Проведён анализ девяти полиморфизмов гена CYP2A6 методом полногеномного генотипирования на платформе Illumina iScan. Статистическая обработка выполнена с использованием критерия Стьюдента, χ²-теста и пермутационного метода Монте-Карло.</p></sec><sec><title>Результаты</title><p>Результаты. Генотип C/C rs8192733 ассоциирован с благоприятным исходом (ОШ=6,922; 95 % ДИ 2,592– 18,486; р &lt;0,001), тогда как генотип G/G — с риском неудачной имплантации (ОШ=0,053; 95 % ДИ 0,017–0,160; р &lt;0,001). Для rs57837628 генотип G/G ассоциирован с 2,4-кратным повышением шансов наступления беременности (ОШ=2,369; 95 % ДИ 0,946–5,936; р=0,010), генотип A/G — с неблагоприятным исходом (ОШ=0,231; 95 % ДИ 0,096–0,559; р &lt;0,001). Значимость подтверждена пермутационным тестом (p-perm &lt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Выявлена взаимосвязь полиморфизмов гена CYP2A6 rs8192733 и rs57837628 с результатами программ ЭКО при трубно-перитонеальном бесплодии.

The effectiveness of in vitro fertilization (IVF) programs remains limited, which necessitates the search for new prognostic markers. The CYP2A6 gene is expressed in estrogen-sensitive tissues, and its activity is regulated by sex steroids, but the contribution of its polymorphisms to IVF outcomes remains poorly understood.</p></sec><sec><title>Objective</title><p>Objective.

A prospective pilot study included 96 women (mean age 31.4 ± 3.7 years) with tuboperitoneal infertility. All participants received therapy according to a short protocol with gonadotropin-releasing hormone antagonists and recombinant follicle-stimulating hormone. Nine polymorphisms of the CYP2A6 gene were analyzed by genome-wide genotyping on the Illumina iScan platform. Statistical processing was performed using Student's test, χ ² test and Monte-</p></sec><sec><title>Carlo permutation method</title><p>Carlo permutation method.</p></sec><sec><title>Results</title><p>Results. The rs8192733 C/C genotype is associated with a favorable outcome (OR = 6.922; 95 % CI: 2.592–18.486; p &lt;0.001), while the G/G genotype is associated with a risk of implantation failure (OR = 0.053; 95 % CI: 0.017–0.160; p &lt;0.001). For rs57837628, the G/G genotype is associated with a 2.4-fold increase in the odds of pregnancy (OR = 2.369; 95 % CI: 0.946–5.936; p = 0.010), the A/G genotype is associated with an unfavorable outcome (OR = 0.231; 95 % CI: 0.096–0.559; p &lt;0.001).

An association was established between the CYP2A6 polymorphisms rs8192733 and rs57837628 and the outcomes of IVF programs in tubal-peritoneal infertility.
