У 140 детей выявлена анемия воспаления, из них 60,7% с рефрактерным (РА), 39,3% с нерефрактерным (нРА) вариантом течения. Общий анализ крови проводили на гематологическом автоматическом анализаторе. Вирусологическую верификацию HBV проводили методом ИФА и ПЦР. Методом ИФА определяли гепсидин-25, сывороточное железо, ферритин (Ft), трансферрин (Tf), растворимые трансферриновые рецепторы (sTfR), провоспалительные цитокины (IL-1, IL-6). Вычислялся индекс sTfR/log10Ft.</p></sec><sec><title>Результаты</title><p>Результаты: в ходе исследования детей с хронической HBV-инфекцией установлена высокая частота анемии воспаления – 94,6%, которая при РА характеризовалась нормоцитарным нормохромным течением, тромбоцитопенией и снижением тромбокрита, при нРА – микроцитарным гипохромным течением с анизоцитозом эритроцитов. Несмотря на высокий воспалительный индекс, индуцированный HBV-вирусной репликацией, для детей с РА характерно снижение значений гепсидина-25 и трасферриновых параметров на фоне высоких значений ферритина, для нРА – повышение гепсидина-25 и трансферринового спектра на фоне сниженных значений сывороточного железа и ферритина.</p></sec><sec><title>Заключение</title><p>Заключение. При хронической HBV-инфекции у детей в генезе развития анемии воспаления установлено два патогенетических варианта: «истинный» дефицит железа с раскладкой ферромаркеров по типу железодефицитной анемии, характерный для нРА, и перераспределительный дефицит железа по типу гемосидероза, свойственный для РА. Приоритетом в дифференциальной диагностике вариантов анемии воспаления является сопоставление параметров индекса sTfR/log10Ft (РА&lt;1,0; нРА&gt;2,0) с ориентировочным уровнем гепсидина-25: при РА&lt;28,68ng/ml, при нРА&gt;56,37ng/ml. Своевременная дифференциальная диагностика вариантов течения анемии воспаления позволяет исключить необоснованное назначение препаратов железа и способствовать снижению развития прогрессирующих форм хронической HBV-инфекции у детей. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: To assess diagnostic importance of iron metabolism markers in the progression of anemia of inflammation (AI) in children with chronic HBV infection.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Among 148 examined children with chronic HBV infection 140 had AI, 60.7% of them with refractory (RA) and 39.3% with non-refractory (nRA) progression variant. Complete blood count was performed using hematologic automatic analyzer. Virologic verification of HBV was done by ELISA and PCR. ELISA was used to determine 25-hepcidin, serum iron, ferritin, trasferrin, sTfR, IL-1, IL-6. The index sTfR/log10Ft was calculated.</p></sec><sec><title>Results</title><p>Results: Performing the examination of children with chronic HBV infection we determined high prevalence of AI, equal to 94.6%, which was characterized by normocyte normochromic progression, thrombocytopenia, thrombocrit decrease in case of RA, and microcyte hypochromic progression with erythrocyte anisocytosis in case of nRA. Despite the high inflammatory index induced by HBV viral replication, children with RA had characteristic decrease in 25-hepcidin and transferrin parameters with background high values of ferritin, while nRA was characterized by rise of 25-hepcidin and transferrin spectrum with low values of serum iron and ferritin.</p></sec><sec><title>Conclusions</title><p>Conclusions. In the genesis of AI in chronic HBV cases two pathogenic variants were determined: true iron deficiency with ferromarkers in the type of IDA characteristic for nRA and redistribution iron deficiency compliant to hemosiderosis characteristic for RA. Priority in the differential diagnosis of AI variants is given to the comparison of sTfR/log10Ft index parameters (RA&lt;1.0; nRA&gt;2.0) with reference level of 25-hepcidin&lt;28,68ng/ml in case of RA, and &gt;56,37ng/ml in case of nRA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая HBV-инфекция</kwd><kwd>анемия воспаления</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic HBV infection</kwd><kwd>anemia of inflammation</kwd><kwd>children</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">Defresne F.
