Целью данного исследования был анализ вклада межгенных и внутригенных комбинаций генотипов SFTPB и SFTPC в патогенез синдрома дыхательного расстройства (СДР) с учетом гендерных различий и бронхолегочной дисплазии (БЛД) у недоношенных детей. У 567 новорожденных были проанализированы полиморфные локусы rs2077079, rs1130866 гена SFTPB и rs4715, rs1124, rs2070687 гена SFTPC с использованием ПЦР в реальном времени с TaqMan-зондами и секвенирования по Сэнгеру. Установлено, что у недоношенных девочек риск развития СДР выше у носителей комбинаций генотипов –18CCSFTPB/413CASFTPC и –18CCSFTPB/436-8CGSFTPC ( р = 0,044 и р = 0,03 соответственно). Сочетание вариантов 1580СТSFTPB/557ААSFTPC связано с тяжелым течением СДР независимо от пола ( р = 0,019). У девочек тяжелое течение СДР ассоциировано с комби- нациями генотипов –18CASFTPB/557CCSFTPC и 1580CT/–18CA SFTPB ( р = 0,018 и p = 0,033 соответственно), а у мальчиков – с сочетанием 1580TTSFTPB/413CCSFTPC ( р = 0,03). В группе недоношенных новорожденных с гестационным возрастом 28–34 недели наличие комбинации 1580СТSFTPB/413ССSFTPC связано с развитием БЛД ( p = 0,031). Таким образом, выявлена значимая ассоциация внутригенных и межгенных комбинаций полиморфных вариантов SFTPB и SFTPC с риском развития и тяжестью течения СДР и БЛД у недоношенных новорожденных.</p></abstract><trans-abstract xml:lang="en"><p>Genetic polymorphisms of surfactant proteins SP-B and SP-C may contribute to the development of respiratory disorders among preterm newborns. The aim of this study was to analyze the contribution of intergenic and intragenic combinations of SFTPB and SFTPC genotypes to the pathogenesis of respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) in preterm infants. A total of 567 newborns were genotyped for the polymorphic loci rs2077079 and rs1130866 of the SFTPB gene as well as rs4715, rs1124, and rs2070687 of the SFTPC gene using real-time PCR with TaqMan probes and Sanger sequencing. In preterm girls, the risk of RDS was significantly higher in those carrying the genotype combinations –18CCSFTPB/413CASFTPC and –18CCSFTPB/436-8CGSFTPC (p = 0.044 and p = 0.03, respectively). The 1580СТSFTPB/ 557ААSFTPC combination was associated with severe RDS regardless of sex (p = 0.019). Among girls, RDS severity was linked to –18CASFTPB/557CCSFTPC and 1580CT/–18CA SFTPB combinations ( p = 0.018 and p = 0.033, respectively), while in boys, the 1580TTSFTPB/413CCSFTPC combination was associated with more severe disease (p = 0.03). In preterm infants with a gestational age of 28–34 weeks, the risk of BPD was associated with the 1580СТSFTPB/413ССSFTPC genotype combination ( p = 0.031). Thus, specific intergenic and intragenic combinations of SFTPB and SFTPC gene polymorphisms are significantly associated with the risk and severity of RDS and BPD in preterm newborns.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм генов</kwd><kwd>комбинации генотипов</kwd><kwd>сурфактантные белки SP-B и SP-C</kwd><kwd>синдром дыхательного расстройства</kwd><kwd>бронхолегочная дисплазия</kwd><kwd>недоношенные новорожденные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene polymorphism</kwd><kwd>genotypes’ combinations</kwd><kwd>surfactant proteins SP-B and SP-C</kwd><kwd>respiratory distress syndrome</kwd><kwd>bronchopulmonary dysplasia</kwd><kwd>preterm infants</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">Факторы риска и структура заболеваемости недоношенных новорожденных с летальным исходом / Г.
