Ингибиторы натрий-глюкозного котранспортера 2 (НГЛТ-2) включены в стандарты лечения хронической болезни почек (ХБП) у больных сахарным диабетом 2 типа (СД2). Идентификация предикторов нефропротективного эффекта ингибиторов НГЛТ-2 остается актуальной задачей.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Оценить эффекты ингибитора НГЛТ-2 эмпаглифлозина на уровень биомаркеров почечного повреждения, фиброза и воспаления низкой интенсивности у больных СД2 с ХБП и/или высоким сердечно-сосудистым риском.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. В проспективное когортное одноцентровое исследование включено 30 больных СД2, впервые начавших лечение ингибитором НГЛТ-2. До начала и на 90-й день лечения эмпаглифлозином (10 мг/сут) определяли мочевую экскрецию нефрина, ретинол-связывающего белка 4 (RBP-4), коллагена IV типа и маркера фиброза WFDC-2, а также высокочувствительного С-реактивного белка (вчСРБ) и рецептора 1А фактора некроза опухолей альфа (TNFRSF1A) в сыворотке крови методом иммуноферментного анализа. Контрольную группу составили 20 здоровых лиц.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Больные СД2 в сравнении с контролем исходно демонстрировали более высокую экскрецию нефрина (p=0,03), RBP-4 (p=0,001), коллагена IV типа (p=0,04) и WDFC-2 (p=0,02), а также более высокие концентрации вчСРБ и TNFSF1A в сыворотке крови (p=0,03). На фоне лечения эмпаглифлозином наблюдалось значимое снижение экскреции RBP-4 (p=0,04) и концентрации TNFRSF1A (p&lt;0,001). Экскреция нефрина, коллагена IV типа, WFDC-2 и уровень вчСРБ значимо не изменились (все p&gt;0,05). Исходная экскреция RBP-4 и уровень в сыворотке TNFRSF1A были ассоциированы с изменениями уровня креатинина на фоне лечения эмпаглифлозином.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. У больных СД2 на фоне применения эмпаглифлозина наблюдается снижение мочевой экскреции RBP-4 и уровня TNFRSF1A в сыворотке крови. Полученные данные могут свидетельствовать о протективном эффекте эмпаглифлозина на дисфункцию канальцев и воспаление низкой интенсивности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title> </title><p> </p></sec><sec><title>BACKGROUND</title><p>BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been implemented into the treatment standards for chronic kidney disease (CKD) in patients with type 2 diabetes (T2D). Identification of predictors of the protective effect of SGLT2 inhibitors on the kidneys remains an urgent task.</p></sec><sec><title>AIM</title><p>AIM: To evaluate the effects of the SGLT2 inhibitor empagliflozin on the levels of biomarkers of renal injury, fibrosis and low-grade inflammation in patients with T2D with CKD and/or high cardiovascular risk.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: This prospective cohort single-center study included 30 patients with T2D newly initiated treatment with an SGLT2 inhibitor. Before and on day 90 of treatment with empagliflozin (10 mg/day), urinary excretion of nephrin, retinol-binding protein 4 (RBP-4), type IV collagen, and fibrosis marker WFDC-2, as well as serum concentrations of high-sensitivity C-reactive protein (hsCRP) and tumor necrosis factor receptor 1A alpha (TNFRSF1A) were determined by ELISA. Twenty healthy individuals were included in the control group.</p></sec><sec><title>RESULTS</title><p>RESULTS: Patients with T2D compared to controls initially demonstrated higher excretion of nephrin (p=0.03), RBP-4 (p=0.001), type IV collagen (p=0.04) and WDFC-2 (p=0.02), as well as higher serum concentrations of hsCRP and TNFSF1A (p=0.03). Empagliflozin treatment was associated with a significant decrease in the excretion of RBP-4 (p=0.04) and TNFRSF1A levels (p&lt;0.001). Excretion of nephrin, type IV collagen, WFDC-2 and hsCRP levels did not change significantly (p&gt;0.05). Baseline RBP-4 excretion and serum TNFRSF1A levels were associated with changes in creatinine levels during empagliflozin treatment.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: In patients with T2D with CKD and/or high cardiovascular risk, empagliflozin treatment resulted in decreased urinary excretion of RBP-4 and serum TNFRSF1A levels. These data may indicate a protective effect of empagliflozin on tubular dysfunction and low-grade inflammation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет 2 типа</kwd><kwd>хроническая болезнь почек</kwd><kwd>фиброз</kwd><kwd>воспаление</kwd><kwd>биомаркер</kwd><kwd>ингибитор натрий-глюкозного котранспортера 2</kwd><kwd>эмпаглифлозин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>type 2 diabetes</kwd><kwd>chronic kidney disease</kwd><kwd>fibrosis</kwd><kwd>inflammation</kwd><kwd>biomarker</kwd><kwd>sodium-glucose cotransporter 2 inhibitor</kwd><kwd>empagliflozin</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет средств гранта Российского научного фонда №23-15-00113.</funding-statement><funding-statement xml:lang="en">Russian Science Foundation (grant No. 23-15-00113)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дедов И.И., Шестакова М.В., Майоров А.Ю., и др.
