Комплексное изучение взаимосвязи сывороточного уровня белка Klotho с кальцификацией сердца и сосудов у больных хронической болезнью почек (ХБП) 1–5D стадий.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследовано 70 пациентов с разными стадиями ХБП, включающими 41 случай хронического гломерулонефрита (ХГН), в том числе 10 при системных заболеваниях, 22 больных тубулоинтерстициальным нефритом (бактериальной, подагрической, лекарственной этиологии) и 7 пациентов с гипертензивным нефросклерозом. Наряду с общеклиническими исследованиями у всех больных с 1–5D стадиями ХБП изучен сывороточный уровень Klotho (иммуноферментный метод ELISA с набором анти-Klotho поликлональных антител). У 57 больных на момент взятия проб крови проводили анализ ригидности сосудов («SphygmoCor», «AtCor Medical», Австралия).</p></sec><sec><title>Результаты</title><p>Результаты. Сывороточная концентрация Klotho различалась среди изученных больных в зависимости от стадии ХБП. При сравнении больных с разными стадиями ХБП оказалось, что снижение концентрации в сыворотке крови больных Klotho при прогрессировании ХБП происходило в обратной корреляционной зависимости от содержания в сыворотке крови неорганического фосфора и интактного паратгормона. У больных ХБП с артериальной гипертензией (n = 49) выявлена связь между снижением уровня Klotho в сыворотке крови и увеличением толщины задней стенки левого желудочка. У этих же больных сниженная концентрация Klotho в сыворотке крови была ассоциирована с большей частотой выявления кальцификатов в сердце и магистральных артериях, увеличением ригидности сосудов и снижением кровотока в артериях голени (лодыжечно-плечевой индекс).</p></sec><sec><title> Выводы</title><p> Выводы. Таким образом, помимо участия в минеральном обмене, при ХБП циркулирующая форма белка Klotho может иметь значение в развитии кардиоваскулярных осложнений — артериальной кальцификации, ремоделирования сердца и сосудов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To study associations between serum soluble Klotho level and vascular calcification in patients with chronic kidney disease (CKD) 1–5 stages.</p></sec><sec><title>Design and methods</title><p>Design and methods. We examined 70 patients with different stages of CKD, including 41 patients with chronic glomerulonephritis, among them 10 with systemic diseases, 22 with tubulo-interstitial nephritis (bacterial, gout and drug-induced) and 7 with hypertensive nephrosclerosis. All 70 patients with 1–5 stages of CRD underwent clinical examination and blood tests for serum Klotho levels by enzyme-linked immunosorbent assay. Vascular stiffness was assessed in 57 patients by applanation tonometry method (SphygmoCor, AtCor Medical, Australia).</p></sec><sec><title> Results</title><p> Results. Serum Klotho levels differed depending on the stage of CKD. When patients with different stages of CKD were compared, a reverse correlation between serum Klotho level and serum phosphorus level and intact parathormone was found in CKD progression. There is a correlation between serum Klotho level and an increase in left ventricular posterior wall thickness in patients with CKD and hypertension (n = 49). Also reduction in serum Klotho level is associated with a greater frequency of calcifications in heart and major arteries, increased vascular stiffness and reduced blood flow in the tibial arteries (ankle-brachial index).</p></sec><sec><title>Conclusions</title><p>Conclusions. Thus, circulating Klotho plays an important role in mineral metabolism in CKD and demonstrates pleiotropic effects that might modify cardiovascular risk through the impact on vascular calcification and cardiovascular remodeling. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая болезнь почек</kwd><kwd>артериальная гипертензия</kwd><kwd>циркулирующая форма белка Klotho</kwd><kwd>эктопическая кальцификация</kwd><kwd>ремоделирование сердца и сосудов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic kidney disease</kwd><kwd>hypertension</kwd><kwd>circulating Klotho protein</kwd><kwd>ectopic calcification</kwd><kwd>cardiovascular remodeling</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">Kidney Disease: Improving Global Outcomes (KDIGO) CKD-MBD Work Group.
