Определить риск развития осложнений, эпизодов отторжения и инфекционных заболеваний с носительством полиморфных вариантов rs1800469 гена TGFB1 у детей-реципиентов печени.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В работе обследовано 219 детей-реципиентов печени в возрасте от 2,4 до 204 месяцев, медиана – 8 месяцев, 92 мальчиков и 127 девочек. Показанием для проведения трансплантации печени детям была терминальная стадия печеночной недостаточности, наступившая в исходе врожденных и приобретенных заболеваний печени. Полиморфные варианты локуса rs1800469 гена TGFB1 тестировали методом полимеразной цепной реакции в режиме реального времени с помощью зондов TaqMan.</p></sec><sec><title>Результаты</title><p>Результаты. Сравнительный анализ распределения частот аллелей rs1800469 гена TGFB1 был проведен в 3х группах реципиентов: 1 – с осложненным течением посттрансплантационного периода в сравнении с группой без серьезных осложнений, 2 - с эпизодами отторжения и без таковых, 3 – с инфекционными осложнениями и без таковых. Во всех обследованных группах детей распределение частот аллелей rs1800469 гена TGFB1 соответствовало закону Харди-Вайнберга (р&gt;0,05). Было показано, что частоты встречаемости вариантов локуса rs1800469 гена TGFB1 не различалась в группах детей-реципиентов печени с осложнениями и без них, с эпизодами отторжения трансплантата и без такового. Достоверные различия во встречаемости различных вариантов rs1800469 наблюдались в группах реципиентов с инфекционными осложнениями и без таковых: генотип С/С встречался в 1,9 раза реже (р=0,0102), аллель С – в 1,3 раза реже (р=0,0175), а аллель Т встречался в 1,4 раза чаще (р=0,0175). Для доминантной модели наследования отношение шансов носительства аллеля Т (C/T+T/T) было в 2,53 раза выше, чем гомозиготного варианта С/С в группе реципиентов с инфекциями, чем без таковых (р=0,0077)</p></sec><sec><title>Выводы</title><p>Выводы. У детей-реципиентов печени осложненное течение посттрансплантационного периода или развитие эпизодов отторжения трансплантата не связано с вариантами rs1800469 гена TGFB1, тогда как риск развития инфекционных осложнений может быть выше у носителей аллеля Т, чем у носителей варианта С/С. Результаты исследования позволяют предполагать, что носительство аллеля Т rs1800469 может увеличивать восприимчивость к инфекционным заболеваниям, и рассматривать данный локус как маркер для профилактики осложнений и подбора дозы иммуносупрессанта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to evaluate the association between carriage of the rs1800469 polymorphism of the TGFB1 gene and the risk of post-transplant complications, rejection episodes, and infectious diseases in pediatric liver recipients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 219 pediatric liver recipients (92 boys, 127 girls), aged 2.4 to 204 months (median 8 months). Indications for liver transplantation (LT) were end-stage liver failure resulting from congenital or acquired liver diseases. Genotyping of the TGFB1 rs1800469 polymorphism was performed using real-time polymerase chain reaction (PCR) with TaqMan probes.</p></sec><sec><title>Results</title><p>Results. A comparative analysis of the allele frequency of rs1800469 of the TGFB1 gene was performed in three groups of pediatric liver recipients: (1) with versus without post-transplant complications, (2) with versus without rejection episodes, and (3) with versus without infectious complications. In all groups, allele frequencies conformed to Hardy–Weinberg equilibrium (p &gt; 0.05). No significant differences in rs1800469 variant distribution were observed between recipients with and without overall complications or between those with and without rejection episodes. However, marked differences emerged between recipients with and without infectious complications: the C/C genotype was 1.9 times less frequent (p = 0.0102), the C allele was 1.3 times less frequent (p = 0.0175), and the T allele was 1.4 times more frequent (p = 0.0175) in the infection group. Under a dominant inheritance model, carriers of the T allele (C/T + T/T) had 2.53-fold higher odds of infection compared with those with the homozygous C/C genotype in the group of recipients with infections than in those without (p = 0.0077).</p></sec><sec><title>Conclusion</title><p>Conclusion. In pediatric liver transplant recipients, the TGFB1 polymorphic variant rs1800469 is not associated with either a complicated post-transplant course or the occurrence of graft rejection episodes. However, carriers of the T allele appear to have an increased risk of infectious complications compared with those with the homozygous C/C genotype. These fi ndings suggest that the rs1800469 T allele may serve as a genetic marker for increased susceptibility to infections and could be considered in strategies for prevention of complications and individualized adjustment of immunosuppressive therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>врожденные болезни печени</kwd><kwd>трансплантация печени</kwd><kwd>rs1800469</kwd><kwd>инфекционные осложнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>congenital liver diseases</kwd><kwd>liver transplantation</kwd><kwd>TGFB1 rs1800469</kwd><kwd>infectious complications</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">Briem-Richter A, Leuschner A, Krieger T, Grabhorn E, Fischer L, Nashan B et al.
