МАТЕРИАЛЫ И МЕТОДЫ: в исследование были включены 86 больных с ХБП II-V стадий недиабетической этиологии (53 % мужчин, 47 % женщин, средний возраст 45 ± 13 лет). В зависимости от степени снижения СКФ все больные были разделены на 3 группы. В 1-ю группу были включены 33 больных с СКФ 89-45 мл/мин; во 2-ю группу - 33 больных с СКФ 44-15 мл/мин; в 3-ю группу - 20 больных, получающих лечение гемодиализом с СКФ &lt; 15мл/мин. В контрольную группу (n=20) были включены лица с СКФ &gt; 90 мл/мин. Всем обследуемым было проведено общеклиническое обследование и трансторакальное эхокардиографическое исследование, определялись уровни цистатина С и мочевой кислоты в сыворотке крови. РЕЗУЛЬТАТЫ: ГЛЖ была диагностирована у 48 из 86 (52%) больных с ХБП, составляя в 1-й группе - 42,4%, во 2-й группе - 63,6%, в 3-й группе -80%. Факторами риска ее развития были возраст (Rs= 0,23, р = 0,016), мужской пол (Rs= 0,29, р = 0,003), индекс массы тела (Rs= 0,38, р &lt; 0,0001), общий холестерин (Rs = 0,3, р = 0,001) и АГ (Rs= 0,56, р&lt;0,0001). Уровень сывороточного цистатина С в 1-й группе составлял 1489,4 ± 520,7 нг/мл, во 2-й группе - 2533,1 ± 621,6 нг/мл, в 3-й группе - 5166,0 ± 1586,6 нг/мл; в контрольной группе - 820,0 ± 224,5 нг/мл. Цистатин С обратно коррелировал с СКФ (Rs = -0,9; р&lt; 0,0001), прямо - с артериальной гипертензией (Rs=0,5, р&lt;0,001) и индексом массы миокарда левого желудочка (ИММЛЖ) (Rs=0,51, р&lt;0,0001) и ГЛЖ (Rs=0,5, р&lt;0,0001), концентрической и эксцентрической моделями ГЛЖ (Rs= 0,4, р&lt;0,0001 и Rs = 0,2, р = 0,04 соответственно). Уровень цистатина С &gt;1150,6 нг/мл с 78% чувствительностью и 62% специфичностью предсказывал развитие ГЛЖ у пациентов с ХБП додиализной стадии (р&lt;0,0001). По данным многофакторного анализа цистатин С и АГ были независимо связаны с ИММЛЖ (ß=0,46, p= 0,02; ß=0,29, p=0,03 соответственно). Гиперурикемия выявлена у 76,7% больных, ее наличие прямо коррелировало с артериальной гипертензией (Rs=0,4 р&lt;0,0001) и ИММЛЖ (Rs = 0,4; р&lt; 0,0001) и цистатином С (Rs=0,5, p&lt;0,0001) и обратно - с СКФ (Rs=-0,57, р&lt;0,0001). При проведении ROC анализа сывороточный уровень мочевой кислоты &gt;424,7 мкмоль/л с 84% чувствительностью и 61% специфичностью ассоциировался с наличием ГЛЖ у пациентов с ХБП додиализной стадии (р&lt;0,001). ВЫВОДЫ. При ХБП III-V стадий повышенные уровни цистатина С и мочевой кислоты могут быть связаны с развитием ГЛЖ.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the study is to evaluate interrelation between levels of cystatin C and uric acid with left ventricular hypertrophy (LVH) in patients with chronic kidney disease (CKD). MATERIALS AND METHODS. The study included 86 patients with non-diabetic 2-5 stage CKD (53% male, 47% female, mean age 45±13 years). According to glomerular filtration rate (GFR) decrease they were divided into 3 groups: the 1 one with GFR (n = 33) 89 - 45 ml/min, the 2 (n = 33) - 44 - 15 ml/min and hemodialysis patients (n = 20) were included in the third group. Control group (n=20) included persons with GFR&gt; 90 ml/min. All patients were performedclinical examination and transthoracic echrocardiography, cystatin C and uric acid levels in serum were measured. RESULTS. LVH was detected in 52% (48 form 86) patients with CkD (in 1 group - 42,4%, 2 group - 63,6%, 3 group - 80%). It was correlated with age (p = 0,23 р = 0,016), male gender (p = 0,29 р = 0,003), body mass index (p= 0,38 р &lt; 0,0001), total cholesterol (p = 0,3 р = 0,001) and arterial hypertension (p = 0,56 р &lt; 0,0001). Cystatin C levels in the 1, 2, 3 groups were 1489,49 ± 520,76 ng/ml; 2533,13 ± 621,66 ng/ml; 5166,02 ± 1586,61 ng/ml respectively, in control group - 820,0±224,5 ng/ml. Cystatin C has inverse correlation with GFR (Rs=-0.9; &lt; 0,0001), was positively correlated with arterial hypertension (p = 0,5, р &lt;0,001), left ventricular mass index (p = 0,51, р&lt; 0,0001), concentric and eccentric LVH models (p=0,5, р&lt;0,0001; p = 0,2, р = 0,04 respectively). Multiple regression analysis showed that factors associated with LVH were systolic blood pressure (ß=0,29, p=0,03) and cystatin C (ß=0,46, p= 0,02). Serum cystatin C level С &gt;1150,6 ng/ml had sensitivity 78% and specificity 62% LVH in ROC-curve analysis. Hyperuricemia was found in 76,6% patients with CKD. It was directly correlated with arterial hypertension (p = 0,4 р &lt; 0,0001), left ventricular mass index (p = 0,4; р&lt; 0,0001) and cystatin C (r = 0,5 p &lt; 0,0001) and negatively with GFR (p = -0,57, р &lt; 0,0001). Uric acid level &gt; 424,7 mkmol/l was detected LVH with sensitivity 84% and specificity 61%. CONCLUSION. In stage 3-5 CKD higher levels of cystatin C and uric acid may be associated with left ventricular hypertrophy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кардиоренальный синдром</kwd><kwd>цистатин С</kwd><kwd>мочевая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiorenal syndrome</kwd><kwd>cystatin C</kwd><kwd>uric acid</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">Ronco C., Haapio M., House A. et al.
