Изучить состояние клубочкового и тубулоинтерстициального аппарата почек в зависимости от уровня N-терминального фрагмента предшественника мозгового натрийуретического пептида (NT-proBNP) у пациентов с гипертонической болезнью (ГБ).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование было включено 119 пациентов с ГБ I-II стадии. Пациентам проводились определение уровня цистатина С и скорости клубочковой фильтрации (СКФcys), рассчитанной по формуле CKD-EPI, уровня липокалина, ассоциированного с  нейтрофильной желатиназой человека (NGAL); определение уровня NT-proBNP; эхокардиография (ЭхоКГ), объемная сфигмоплетизмография. В первом анализе пациенты были разделены на две группы в  зависимости от  уровня NT-proBNP. Первую группу составили 32 пациента с  уровнем NT-proBNP &gt;125 пг/мл, вторую группу  — 87 пациентов с  уровнем NT-proBNP &lt;125 пг/мл. Эмпирическим путем была найдена точка разделения NT-proBNP для оценки роли цистатина С  — 75 пг/мл. В  первую группу вошел 41 пациент с уровнем NT-proBNP &gt;75 пг/мл, во вторую группу — 78 пациентов с уровнем NT-proBNP &lt;75 пг/мл.</p></sec><sec><title>Результаты</title><p>Результаты. В первой группе при NT-proBNP &gt;125 пг/мл концентрация NGAL была статистически значимо выше, чем во второй группе 2,50 [1,90;2,85] vs 1,30 [0,9;2,0] нг/мл (р=0,022). Пациенты в группах статистически значимо не отличались по  концентрации цистатина С  в  крови и  СКФcys (р=0,099 и  р=0,090, соответственно). При разделении пациентов по концентрации NT-proBNP 75 пг/мл получены следующие данные. Концентрация цистатина С  в  первой группе с  NT-proBNP &gt;75 пг/мл составила 1041,50 [995,00;1185,00] vs 964,30 [801,00;1090,00] нг/мл во второй группе (р=0,034). Пациенты в группах статистически значимо отличались по СКФcys (р=0,027). При проведении корреляционного анализа выявлена средней степени зависимости прямая взаимосвязь NT-proBNP с  уровнем цистатина С  (r=0,32; p&lt;0,005) и  уровнем NGAL (r=0,36; p&lt;0,05), а также средней степени зависимости обратная взаимосвязь со СКФcys (r=-0,35; p&lt;0,005).</p></sec><sec><title>Заключение</title><p>Заключение. NT-proBNP может быть использован как интегративный инструмент для стратификации риска поражения клубочкового и интерстициального аппарата почек у больных ГБ. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To assess the state of the glomerular and tubulointerstitial apparatus depending on the level of the N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with hypertension (HTN).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 119 patients with stage I-II HTN (target organ damage classification). We determined the cystatin C level, glomerular filtration rate (GFF) using the CKD-EPI equation, neutrophil gelatinase‐associated lipocalin (NGAL) and NT-proBNP levels; echocardiography and sphygmoplethysmography was performed. In the first analysis, patients were divided into two groups depending on the NT-proBNP level. Group 1 (n=32) consisted of patients with NTproBNP level &gt;125 pg/ml, group 2 (n=87)  — with NT-proBNP level &lt;125 pg/ml. Empirically, the NT-proBNP cutoff point (75 pg/ml) was found to assess the role of cystatin C. The first group included 41 patients with NT-proBNP level &gt;75 pg/ml, the second group — 78 patients with NT-proBNP level &lt;75 pg/ml.</p></sec><sec><title>Results</title><p>Results. In the group 1 (NT-proBNP &gt;125 pg/ml) the NGAL concentration was significantly higher than in the group 2: 2,50 [1,90;2,85] vs 1,30 [0,9;2,0] ng/ml, respectively (p=0,022). Patients in the groups did not significantly differ in the cystatin C levels and GFR (p=0,099 and p=0,090, respectively). When dividing patients according to the NT-proBNP cutoff point (75 pg/ml), the following data were obtained. The concentration of cystatin C in the first group with NT-proBNP &gt;75 pg/ml was 1041,50 [995,00;1185,00] vs 964,30 [801,00;1090,00] ng/ml in the second group (p=0,034). Patients in the groups significantly differed in GFR (p=0,027). A correlation analysis revealed a moderate, direct relationship of NT-proBNP with cystatin C (r=0,32; p&lt;0,005) and NGAL levels (r=0,36; p&lt;0,05), as well as a moderate, inverse relationship with GFR (r=-0,35; p&lt;0,005).</p></sec><sec><title>Conclusion</title><p>Conclusion. NT-proBNP determination can be used as an integrative risk stratification tool for glomerular and tubulointerstitial injury in HTN patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>натрийуретический пептид</kwd><kwd>клубочковый и  тубулоинтерстициальный аппарат почек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natriuretic peptide</kwd><kwd>glomerular and tubulointerstitial apparatus</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">Forouzanfar MH, Liu P, Roth GA, et al.
