Дефицит железа (ДЖ) имеет распространение среди пациентов с легочной артериальной (ЛАГ) и хронической тромбоэмболической легочной гипертензией (ХТЭЛГ), ухудшая переносимость физических нагрузок. Диагностика скрытого железодефицита осложнена влиянием воспаления на показатели обмена железа. Перспективными маркерами считаются L- и H-субъединицы ферритина. Цель: оценить возможности использования субъединиц ферритина в дифференциальной диагностике абсолютного и функционального (на фоне воспаления) дефицита железа у пациентов с прекапиллярной легочной гипертензией. Материалы и методы. В исследование вошло 20 пациентов с ЛАГ и 47 с ХТЭЛГ. Всем пациентам выполнялись эхокардиографическое исследование, катетеризация правых камер сердца и тест с 6-минутной ходьбой (ТШХ), а также оценка лабораторных маркеров сердечной недостаточности, системного воспаления и обмена железа. Результаты. Были обнаружены умеренные корреляционные связи между СФ и его субъединицами с МСР-1, что указывает на роль воспаления в изменении уровня ферритина. Повышение СФ в группе ХТЭЛГ обусловлено L- и H-субъединицами. Исследование также показало корреляции обеих субъединиц ферритина с маркерами дефицита железа, такими как НТЖ и sTfRF, однако различий в соотношении субъединиц при абсолютном и функциональном ДЖ выявлено не было. Заключение. В статье представлены результаты исследования корреляций между сывороточным ферритином (СФ) и его субъединицами с маркерами воспаления и дефицита железа у пациентов с вариантами прекапиллярной легочной гипертензии (ЛАГ и ХТЭЛГ). Однако возможности использования субъединиц СФ для дифференциальной диагностики абсолютного и функционального дефицита железа остаются ограниченными. Результаты исследования имеют важное значение для понимания механизмов дефицита железа при ЛАГ и ХТЭЛГ.</p></abstract><trans-abstract xml:lang="en"><p>Background. Iron deficiency (ID) is a common issue among patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH), negatively impacting their exercise tolerance. Identifying latent iron deficiency in these groups is challenging due to the influence of chronic inflammation on interpreting iron metabolism markers. The L- and H-subunits of ferritin are promising candidates for assessing iron deficiency. Objective is to evaluate the possibilities of using ferritin subunits in the differential diagnosis of absolute and functional (against the background of inflammation) iron deficiency in patients with variants of precapillary pulmonary hypertension. Methods. Study involved 20 PAH and 47 CTEPH patients undergoing echocardiography, right heart catheterization, 6-minute walk tests, and lab assessments of heart failure, inflammation, and iron metabolism. Results. Moderate correlations were found between serum ferritin (SF) and its subunits with MCP-1, which indicates the role of inflammation in changing ferritin levels. The increase in SF in the CTEH group is due to the L- and H-subunits. The study also showed correlations of both ferritin subunits with markers of iron deficiency, such as TSAT and sTfRF, but there were no differences in the ratio of subunits at absolute and functional ID. Conclusion. Findings provide insights into SF/subunit correlations with inflammation/iron markers in PAH/CTEPH, though their utility for differential diagnosis remains limited. The results of the study are important for understanding the mechanisms of iron deficiency in PAH and CTEPH.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воспаление</kwd><kwd>дефицит железа</kwd><kwd>легочная артериальная гипертензия</kwd><kwd>субъединицы ферритина</kwd><kwd>сывороточный ферритин</kwd><kwd>хроническая тромбоэмболическая легочная гипертензия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic thromboembolic pulmonary hypertension</kwd><kwd>ferritin subunits</kwd><kwd>inflammation</kwd><kwd>iron deficiency</kwd><kwd>pulmonary arterial hypertension</kwd><kwd>serum ferritin</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке гранта Российского научного фонда № 23-75-01057, https://rscf.ru/project/23-75-01057/ (Соглашение № 23-75- 01057 от 08.08.2023).</funding-statement><funding-statement xml:lang="en">The research was supported by a grant from the Russian Science Foundation No. 23-75-01057, https://rscf.ru/project/23-75-01057 / (Agreement No. 23-75-01057 dated 08/08/2023).</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">Sonnweber T, Nairz M, Theurl I, et al.
