Целью данного исследования являлась разработка методических подходов к раннему выявлению острого повреждения почек токсического генеза на основе динамики ряда биомаркеров на 1, 3 и 7 сутки после введения нефротоксина. Для почечных биомаркеров, отражающих величину скорости клубочковой фильтрации (креатинин в крови, cutoff 112,77 мкмоль/л), механизм гибели клеток (ТРА в моче, cutoff 5,28 мЕ/мл), дистрофические изменения и регенерацию (KIM-1 в моче, cutoff 0,28 нг/мл; значения выше 8,2 нг/мл имели прогностическое в отношении летального эффекта значение), воспалительную инфильтрацию и индукцию репарации ткани (MCP-1 в моче, cutoff 11,70 пг/мл и TGF-β1 в моче, cutoff 34,33 пг/мл) определены чувствительность и специфичность. По последовательности увеличения уровня в моче изученные биомаркеры можно расположить в следующий ряд: ранняя стадия – TPA; стадия нарастания некроза и лейкоцитарной инфильтрации – KIM-1, MCP-1, креатинин; стадия глубоких некротических изменений – TGF-β1. Изученные маркеры представляют интерес для использования в качестве диагностических средств при определении стадии патологии почек при отравлении нефротоксичными веществами.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of the experimental toxicological study of rats poisoned with uranyl acetate dihydrate (300 mg / kg body weight). The aim of this study was to develop methodological approaches to the early detection of acute toxic kidney damage on the basis of the dynamics of some biomarkers on 1, 3 and 7 days after nephrotoxin administration. For renal biomarkers reflecting the value of glomerular filtration rate (creatinine in the blood, cutoff 112,77 µmol/l) the mechanism of cell death (TPA in urine, cutoff of 5.28 IU/ml), degenerative changes and regeneration (KIM-1 in urine, cutoff of 0.28 ng/ml; at values above 8,2 ng/ml the lethal effect can be expected), the inflammatory infiltration and the induction of tissue reparation (MCP-1 in urine, cutoff 11,70 pg/ml, TGF-β1 in the urine, cutoff 34,33 pg/ml), the sensitivity and specificity have been determined. According to the sequence of urine level increase, the studied biomarkers can be arranged in the following series: early stage – TPA; stage of necrosis growth and leukocyte infiltration – KIM-1, MCP-1, creatinine; stage of deep necrotic changes – TGF-β1. The studied markers are of interest for use as diagnostic tools in determining the stage of kidney disease in nephrotoxic poisoning.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острое повреждение почек</kwd><kwd>уран</kwd><kwd>биомаркеры</kwd><kwd>крысы</kwd><kwd>моча</kwd><kwd>креатинин</kwd><kwd>ТРА</kwd><kwd>KIM-1</kwd><kwd>MCP-1</kwd><kwd>TGF-β1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute kidney damage</kwd><kwd>uranium</kwd><kwd>biomarkers</kwd><kwd>rats</kwd><kwd>urine</kwd><kwd>creatinine</kwd><kwd>TPA</kwd><kwd>KIM-1</kwd><kwd>MCP-1</kwd><kwd>TGF-β1</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">KDIGO Clinical Practice Guideline for Acute Kidney Injury.
