Дефицит оксида азота, который может возникать в связи с накоплением эндогенных конкурентных ингибиторов, — одно из ключевых звеньев патогенеза легочной гипертензии (ЛГ). В работе предпринята попытка изучить перспективы использования асимметричного диметиларгинина (АДМА) в качестве биомаркера для оценки степени тяжести пациентов с ЛГ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 56 пациентов с ЛГ (средний возраст 42,8 ± 14,5 года, 39 женщин и 17 мужчин): 32 пациента c идиопатической легочной артериальной гипертензией, 7 пациентов с легочной артериальной гипертензией на фоне корригированных врожденных пороков сердца, 6 больных системной склеродермией и 11 пациентов с хронической тромбоэмболической ЛГ. Группу контроля составили 12 здоровых добровольцев (возраст 41,8 ± 10,3 года, 9 женщин и 3 мужчин). Всем пациентам с ЛГ выполнялись: тест с 6-минутной ходьбой (ТШХ), катетеризация правых камер сердца, эхокардиография и эргоспирометрия. В работе оценивали уровень АДМА в сыворотке иммуноферментным методом, концентрацию натрийуретического пропептида NT-proBNP (Elecsys) и мочевой кислоты в сыворотке крови.</p></sec><sec><title> Результаты</title><p> Результаты. В исследование включено 23 % пациентов с симптомами ЛГ II  функциональ-функционального класса (ФК) (по классификации Всемирной организации здравоохранения), 59 % — с III ФК и 13 % — с IV ФК. О тяжести обследованных больных свидетельствовало снижение толерантности к физической нагрузке (ТШХ 362 ± 97 м), повышение концентрации NTproBNP (1833 ± 2176 пг/мл) и мочевой кислоты (463 ± 177 мкмоль/л). У пациентов с ЛГ выявлено повышение уровня АДМА в плазме крови по сравнению с контрольной группой (0,68 ± 0,25 против 0,35 ± 0,12 мкмоль/л, p &lt; 0,05). По результатам корреляционного анализа установлены связи между уровнем АДМА и давлением в правом предсердии (r = 0,31; p &lt; 0,05), ударным объемом левого желудочка (r = -0,34 p = 0,01) по данным катетеризации правых камер сердца. Выявлена связь между уровнем АДМА и таким прогностическим биомаркером, как NT-proBNP (r = 0,44? p = 0,001). Помимо этого, выявлены обратные связи между уровнем АДМА и пройденной дистанцией в ТШХ (r = -0,37; p = 0,004), а также пиковой мощностью физической нагрузки по данным эргоспирометрии (r = -0,42? p = 0,02).</p></sec><sec><title> Выводы</title><p> Выводы. Повышение сывороточного уровня АДМА у больных ЛГ связано с основными прогностическими маркерами. Определение уровня АДМА в сыворотке крови может быть дополнительным критерием в оценке тяжести пациентов с ЛГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. Asymmetrical dimethylarginine (ADMA) is an endogenous nitric oxide inhibitor. Increased level ADMA may contribute to endothelial dysfunction in patients with pulmonary hypertension (PH). The aim of the study was to assess the possible link between ADMA and basic determinants of PH severity.</p></sec><sec><title>Design and methods</title><p>Design and methods. We examined 56 patients with PH (mean age 42,8 ± 14,5 years, 19 males): idiopathic pulmonary arterial hypertension was diagnosed in 32 subjects, 7 subjects had corrected congenital heart disease, 7 subjects had scleroderma, and 11 — inoperable chronic thromboembolic pulmonary hypertension, and 12 healthy subjects formed control group (41,8 ± 10,3 years, 3 males). Serum ADMA by ELISA method, serum NT pro-BNP (Elecsys) and uric acid levels were determined. Echocardiography, 6-minute walking test (6MWT), right heart catheterization and cardiopulmonary exercise testing (CPX) were performed.</p></sec><sec><title>Results</title><p>Results. The symptoms of II functional class (FC) WHO were present in 23 % patients, III FC — in 59 % patients and IV FC — in 13 % patients, 6MWT was decreased (362 ± 97 m) and NT-proBNP level was elevated (1833 ± 2176 pg/ml). Serum ADMA level in patients with PH were elevated in comparison with healthy controls (0,68 ± 0,25 vs 0,35 ± 0,12 µmol/l? p &lt; 0,05). ADMA levels correlated with such prognostic markers as NT-proBNP (r = 0,44? p = 0,0008), mean right atrium pressure (r = 0,31? p &lt; 0,05) and stroke volume LV (r = -0,34? p = 0,01). Serum ADMA was negatively correlated with 6MWT distance (r = -0,37? p = 0,004), work load by CPX (r = -0,42? p = 0,02).</p></sec><sec><title>Conclusions</title><p>Conclusions. Serum ADMA level is elevated in patients with PH and correlates with prognostic markers. Also ADMA level predicts exercise intolerance. We assume that ADMA is a marker of endothelial dysfunction, and could be used for the assessment of PH severity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>легочная гипертензия</kwd><kwd>асимметричный диметиларгинин</kwd><kwd>прогностический маркер</kwd><kwd>функциональный класс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypertension</kwd><kwd>asymmetric dimethylarginine</kwd><kwd>prognostic marker</kwd><kwd>functional class</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">Sibal L., Agarwal S.C., Home P.D. et al.
