В исследование включены 62 ЭОД, 44 мужчины (71%) и 18 женщин (29%) в возрасте от 17 до 64 лет. Забор органов был проведен в учреждениях здравоохранения Гомельской области в 2019–2022 гг. Проводилось бактериологическое исследование биопсийного материала, взятого из разных отделов кишечника, мезентериальных лимфатических узлов (МЛУ) и селезенки. Наличие БТ подтверждалось при получении бактериального роста из гомогенизата МЛУ и(или) селезенки при выделении идентичного штамма из просвета кишечника. Оценивались антропометрические характеристики ЭОД, гематологические, биохимические показатели, время нахождения пациента в отделении интенсивной терапии и реанимации (ОИТР).</p></sec><sec><title>Результаты</title><p>Результаты. Признаки бактериальной транслокации выявлены у 22 ЭОД (35,5%; 95% ДИ 24,7–48,0). У 21 пациента (95,5%) получен рост в МЛУ, а у 7 (31,8%) – в биоптате селезенки. ЭОД были разбиты на две группы в зависимости от наличия факта БТ, проведено сравнение основных характеристик. С помощью ROC-анализа определены прогностические значения основных показателей. Факторами риска БТ являются уровень сывороточного натрия на момент забора более 144 ммоль/л (AUC = 0,759), вес более 89 кг (AUC = 0,756), ИМТ более 27,5 (AUC = 0,709), снижение уровня гемоглобина менее 126 г/л (AUC = 0,665), нахождение в ОИТР более 2 суток (AUC = 0,656).</p></sec><sec><title>Заключение</title><p>Заключение. Среди эффективных органных доноров бактериальная транслокация определяется с частотой 35,5% и сопровождается проникновением бактерий и дрожжеподобных грибов в МЛУ и селезенку. Наличие бактериальной транслокации ассоциируется с избыточной массой тела, гипернатриемией, длительностью нахождения в условиях ОИТР, а также со снижением уровня гемоглобина на момент эксплантации. Данные факторы необходимо учитывать при медицинском сопровождении органного донора со смертью головного мозга (кондиционировании органных доноров).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to ascertain the prevalence and risk factors for bacterial translocation (BT) in brain-dead donors (BDDs) during organ and tissue retrieval in health care facilities.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 62 BDDs, featuring 44 males (71%) and 18 females (29%), aged 17 to 64 years. Organ was retrieved in healthcare institutions located in Gomel Oblast in 2019–2022. Bacteriological examination of biopsy material taken from different parts of the intestine, mesenteric lymph nodes (MLNs) and spleen was carried out. The presence of BT was validated when bacterial growth was obtained from homogenized MLNs and(or) spleen by isolating an identical strain from the intestinal lumen. The anthropometric characteristics of BDDs, hematologic, biochemical parameters, and the length of stay in the intensive care unit (ICU) were assessed.</p></sec><sec><title>Results</title><p>Results. Evidence of bacterial translocation was detected in 22 BDDs (35.5%, 95% CI 24.7–48.0). Growth in MLNs and in spleen biopsies was noted in 21 (95.5%) and 7 (31.8%) patients, respectively. The BDDs were categorized into two groups depending on the presence of BT, and the main characteristics were compared. ROC analysis was used to determine the prognostic significance of the main parameters. Risk factors for BT were serum sodium level &gt;144 mmol/L (AUC = 0.759) at the time of retrieval, weight &gt;89 kg (AUC = 0.756), BMI &gt;27.5 (AUC = 0.709), decreased hemoglobin &lt;126 g/L (AUC = 0.665), and ICU stay &gt;2 days (AUC = 0.656).</p></sec><sec><title>Conclusion</title><p>Conclusion. Bacterial translocation is found in 35.5% of BDD cases, and it is accompanied by penetration of bacteria and yeast-like fungi into the MLNs and spleen. Bacterial translocation is linked to excess body weight, hypernatremia, prolonged ICU stay, and decreased hemoglobin levels at the time of retrieval. These factors should be taken into account in the medical management of brain-dead donors (organ donor conditioning).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>умерший органный донор</kwd><kwd>бактериальная транслокация</kwd><kwd>трансплантация органов</kwd><kwd>трансплантационная координация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deceased organ donor</kwd><kwd>bacterial translocation</kwd><kwd>organ transplantation</kwd><kwd>transplantation</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">Резник ОН, Резник АО.
