В последние годы неалкогольная жировая болезнь печени (НАЖБП) считается печёночным проявлением метаболического синдрома. Основным последствием НАЖБП является хроническое воспаление печени, которое приводит к дислипидемии, воспалению, усилению окислительного стресса и дисфункции эндотелия. Иммунная активация в ответ на взаимодействие с агентами метаболической природы индуцирует в печени высвобождение провоспалительных цитокинов, которые впоследствии приводят к нарушению гомеостаза железа. Это приводит к частой ассоциации НАЖБП с анемиями различной этиологии. В связи с этим мы посчитали важным оценить выраженность системного воспалительного ответа при НАЖБП в эксперименте с целью диагностики анемии хронического воспаления.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование проведено на 26 крысах-самцах линии Wistar, которые были разделены на контрольную и экспериментальную группы. У животных экспериментальной группы моделировалась НАЖБП по общепринятой методике. С целью оценки метаболических нарушений определяли основные биохимические показатели, общий анализ крови с подсчётом эритроцитарных индексов, концентрацию основных провоспалительных цитокинов – интерлейкина (ИЛ) 1, ИЛ-6.</p></sec><sec><title>Результаты</title><p>Результаты. У лабораторных крыс с НАЖБП регистрировалось статистически значимое повышение в сыворотке крови внутрипечёночных ферментов. Состояние эритроцитарного ростка гемопоэза у животных экспериментальной группы прогрессивно ухудшалось, приводя к развитию анемического синдрома. Синхронно регистрировалось статистически значимое повышение в сыворотке уровней ИЛ-1, ИЛ-6, что подтверждает корреляцию НАЖБП с анемией хронического воспаления.</p></sec><sec><title>Выводы</title><p>Выводы. Высокая концентрация цитокинов ИЛ-1, ИЛ-6 при НАЖБП ингибирует всасывание железа в двенадцатиперстной кишке, приводит к активации макрофагов, блокируя высвобождение железа, переработанного из стареющих эритроцитов в плазму. Дальнейшее изучение механизмов развития анемии при НАЖБП предоставляет важные терапевтические мишени в лечении как НАЖБП, так и сопутствующих заболеваний.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim of the study</title><p>The aim of the study. In recent years, non-alcoholic fatty liver disease (NAFLD) has been considered a hepatic manifestation of the metabolic syndrome. The main consequence of NAFLD is chronic hepatic inflammation, which leads to dyslipidemia, inflammation, increased oxidative stress, and endothelial dysfunction. Immune activation in response to interaction with agents of a metabolic nature induces the release of pro-inflammatory cytokines in the liver, which subsequently cause iron сhomeostasis disorder. This leads to a frequent association of NAFLD with anemia of various etiology. In this regard, we considered it important to assess the severity of the systemic inflammatory response in NAFLD in the experiment in order to -diagnose anemia of chronic inflammation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was carried out on 26 male Wistar rats, which were divided into control and experimental groups. In animals of the experimental group, NAFLD was modeled according to the generally accepted method. In order to assess metabolic disorders, we determined the main biochemical parameters, a complete blood count with the calculation of erythrocyte indices, the concentration of the main pro-inflammatory cytokines – interleukin (IL) 1, IL-6. </p></sec><sec><title>Results</title><p>Results. In laboratory rats with NAFLD, a statistically significant increase of intrahepatic enzymes in blood serum was found. The state of the erythrocyte lineage of hematopoiesis in the experimental group progressively worsened and caused the development of anemic syndrome. Synchronously, a statistically significant increase in serum levels of IL-1, IL-6 was recorded, which confirms the correlation of NAFLD with anemia of chronic inflammation.</p></sec><sec><title>Conclusions</title><p>Conclusions. A high concentration of IL-1, IL-6 cytokines in NAFLD inhibits iron absorption in the duodenum, leads to the activation of macrophages, blocking the release of iron processed from aging erythrocytes into plasma. Further study of the mechanisms of anemia in NAFLD provides important therapeutic targets in the treatment of both NAFLD and its comorbidities.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>неалкогольная жировая болезнь печени</kwd><kwd>анемия хронического воспаления</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-alcoholic fatty liver disease</kwd><kwd>anemia of chronic inflammation</kwd><kwd>rats</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке гранта ректора ФГБОУ ВО «Санкт-Петербургский государственный педиатрический медицинский университет» Минздрава России 2022 года.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cobbina E, Akhlaghi F.
