Оценить распространенность железодефицитных состояний у пациентов с хронической тромбоэмболической легочной гипертензией (ХТЭЛГ), их влияние на выживаемость и функциональный статус больных, а также поиск наиболее информативного показателя оценки дефицита железа (ДЖ) в данной группе.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 283 пациента с впервые поставленным согласно текущим клиническим рекомендациям диагнозом ХТЭЛГ (средний возраст 56,0 [44,0; 67,0] лет, 47% мужчин). Всем пациентам исследовали показатели обмена железа: железо сыворотки, трансферрин, ферритин сыворотки (СФ), растворимые трансферриновые рецепторы; уровень провоспалительных цитокинов: интерлейкина (ИЛ)-6, -8, -10 и моноцитарный хемотаксический протеин (MCP-1), а также гепсидина и эндотелина-1. Группу контроля составили 24 здоровых донора (средний возраст 58 [39; 64] лет; 46% мужчин).</p></sec><sec><title>Результаты</title><p>Результаты. Распространенность анемии составила 17% (n=48), а доля пациентов с железодефицитной анемией 78% (n=37). Не выявлено различий по показателям гемодинамики малого круга кровообращения и функционального статуса при сравнении пациентов с анемией и без таковой, а также влияния анемии на трехлетнюю выживаемость пациентов. Продемонстрировано повышение уровня С-реактивного белка, ИЛ-10 и МСР-1 у пациентов с ХТЭЛГ и их ассоциация с показателями обмена железа. В зависимости от используемых критериев распространенность ДЖ варьировала от 24,5% до 69,1%. Для показателя насыщения трансферрина железом (НТЖ) была установлена слабая прямая корреляционная связь с такими прогностическими показателями, как тест с 6-минутной ходьбой (r=0,21; p=0,032), пиковое потребление кислорода (r=0,26; p=0,044) и насыщение кислородом смешанной венозной крови (r=0,34; p=0,040), а также значимые различия по показателям тяжести ХТЭЛГ при делении на группы по значению НТЖ более/менее 20%. При анализе трехлетней выживаемости пациентов с ХТЭЛГ получены значимые отличия выживаемости для критериев ДЖ на основании уровня растворимых рецепторов трансферрина (ж &gt;4,4; м &gt;5,0 (Roche Diagnostics)) и предложенных нами критериев ДЖ (СФ &lt;30 мкг/л или 30&lt; СФ &lt;299 мкг/л при НТЖ &lt;20%).</p></sec><sec><title>Заключение</title><p>Заключение. Получены данные в пользу диагностической значимости показателя НТЖ для диагностики дефицита железа у пациентов с ХТЭЛГ и предложены дополненные критерии ДЖ для данной подгруппы пациентов с легочной гипертензией.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the prevalence of iron deficiency in patients with chronic thromboembolic pulmonary hypertension (CTEPH), their impact on survival and functional status, and to identify the most informative indicator for assessing iron deficiency (ID) in this group.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 283 patients with a newly diagnosed CTEPH (mean age 56,0 [44,0; 67,0] years, 47% men). All patients underwent iron metabolism (serum iron, transferrin, serum ferritin, soluble transferrin receptors), proinflammatory cytokine (interleukin (IL)-6, -8, -10 and monocyte chemotactic protein (MCP-1)), hepcidin, and endothelin-1 tests. The control group consisted of 24 healthy donors (mean age, 58 [39; 64] years; men, 46%).</p></sec><sec><title>Results</title><p>Results. The prevalence of anemia was 17% (n=48), and the proportion of patients with iron deficiency anemia was 78% (n=37). No differences were found in pulmonary circulation hemodynamics or functional status when comparing patients with and without anemia, nor was there an effect of anemia on three-year patient survival. An increase in the level of C-reactive protein, IL-10 and MCP-1 in patients with CTEPH and their association with iron metabolism parameters were demonstrated. Depending on the criteria used, the prevalence of ID ranged from 24,5% to 69,1%. For the transferrin saturation, a weak direct correlation was established with such prognostic indicators as the 6-minute walk test (r=0,21; p=0,032), peak oxygen consumption (r=0,26; p=0,044) and mixed venous oxygen saturation (r=0,34; p=0,040). In addition, significant differences in the severity of CTEPH were revealed when dividing into groups according to transferrin saturation value of more/less than 20%. Three-year survival analysis in patients with CTEPH revealed significant differences in survival rates for ID criteria based on soluble transferrin receptor levels (&gt;4,4 for men; &gt;5,0 for women (Roche Diagnostics)) and our proposed ID criteria (serum ferritin (SF) &lt;30 μg/L or 30&lt;SF&lt;299 μg/L with transferrin saturation &lt;20%).</p></sec><sec><title>Conclusion</title><p>Conclusion. Evidence was obtained to support the diagnostic value of transferrin saturation for diagnosing ID in patients with CTEPH, and supplemented ID criteria were proposed for this subgroup of patients with pulmonary hypertension.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая тромбоэмболическая легочная гипертензия</kwd><kwd>легочная гипертензия</kwd><kwd>анемия</kwd><kwd>дефицит железа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic thromboembolic pulmonary hypertension</kwd><kwd>pulmonary hypertension</kwd><kwd>anemia</kwd><kwd>iron deficiency</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">Авдеев С.
