Среди перинатальных инфекций значение внутриутробного энцефалита (ВУЭ) определяется высокой летальностью у плодов и новорожденных и развитием инвалидности в последующие периоды жизни, в том числе – детских церебральных параличей, шизофренических и аутистических расстройств. Морфологическая картина ВУЭ характеризуется значительным полиморфизмом, что обусловлено как полиэтиологичностью энцефалитов, так и гетероформным реагированием нейронов в условиях патологии.</p></sec><sec><title>Ц е л ь</title><p>Ц е л ь . Изучение этиологии и морфологических особенностей ВУЭ и его исходов.</p><p>М а т е р и а л ы и м е т о д ы . Исследовали головной мозг 37 плодов и новорожденных при сроке гестации 24–27 нед, у которых морфологически выявляли признаки ВУЭ. Использовали методы световой микроскопии и иммуногистохимического исследования. Методом иммуногистохимического типирования определяли маркеры следующих возбудителей: Herpes simplex 1 и 2-го типов, цитомегаловируса, Toxoplasma gondii, вируса Эпштейна – Барр.</p></sec><sec><title>Р е з у л ь т а т ы</title><p>Р е з у л ь т а т ы . ВУЭ чаще всего был проявлением генерализованной внутриутробной инфекции – 86,48 % случаев. Морфологическая картина при ВУЭ характеризовалась двумя основными проявлениями: продуктивным энцефалитом, в том числе и гранулематозным, и экссудативно-продуктивным энцефалитом, что отражает, вероятно, его этиологические особенности. Этиология ВУЭ: преобладали возбудители вирусной (66,7 %) и бактериальной и грибковой (33,3 %) природы. ВУЭ осложнялся геморрагическим синдромом с развитием летальных форм: субэпендимальным кровоизлиянием – 21,68 % (8 наблюдений), внутрижелудочковыми кровоизлияниями – 16,2 % (6 наблюдений).</p></sec><sec><title>З а к л ю ч е н и е</title><p>З а к л ю ч е н и е . Развитие ВУЭ у плодов и новорожденных является тяжелой формой генерализованной внутриутробной инфекции, связанной преимущественно с возбудителями TORCH-комплекса, осложнениями которой выступают летальные субэпендимальные и внутриужелудочковые кровоизлияния.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>I n t r o d u c t i o n</title><p>I n t r o d u c t i o n . Among perinatal infections, the significance of intrauterine encephalitis (IUE) is determined by the high mortality rate in fetuses and newborns and the development of disabilities in subsequent periods of life, including cerebral palsy, schizophrenic, and autistic disorders. The morphological picture of IUE is characterized by significant polymorphism, which is due to both the multietiological nature of encephalitis and different types of neuron response under pathological conditions.</p></sec><sec><title>A i m</title><p>A i m . Studying the etiology and morphological features of IUE and its outcomes.</p><p>M a t e r i a l s a n d m e t h o d s . The brains of 37 fetuses and newborns at a gestation period of 24–27 were examined, in which the signs of IUE were detected morphologically. Light microscopy and immunohistochemical examination were used. By immunohistochemical typing, the markers of the following pathogens were determined: herpes simplex virus types 1 and 2, cytomegalovirus, Toxoplasma gondii, Epstein-Barr virus.</p></sec><sec><title>R e s u l t s</title><p>R e s u l t s . IUE was at most a manifestation of systemic intrauterine infection – 86,48% of cases. The morphological picture in IUE was characterized by two main manifestations: productive encephalitis, including granulomatous one, and exudative and productive encephalitis, which probably reflects its etiological features. Etiology of IUE: viral (66,7%), bacterial and fungal (33,3%) pathogens predominated. IUE was complicated by hemorrhagic syndrome with the development of fatal forms: in 21,68% (8 cases) – by subependymal hemorrhages, in 16,2% (6 cases) – by intraventricular hemorrhages.</p></sec><sec><title>C o n c l u s i o n</title><p>C o n c l u s i o n . The IUE development in fetuses and newborns is a severe form of systemic intrauterine infection associated primarily with the pathogens of the TORCH complex, the complications of which are fatal subependymal and intraventricular hemorrhages.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внутриутробный энцефалит</kwd><kwd>перинатальная инфекция</kwd><kwd>морфология</kwd><kwd>этиология</kwd><kwd>перинатальное поражение ЦНС</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intrauterine encephalitis</kwd><kwd>perinatal infection</kwd><kwd>morphology</kwd><kwd>etiology</kwd><kwd>perinatal CNS lesions</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">Deng Y., Wang R., Zhou X. et al.
