Результаты ряда основополагающих для диабетологии исследований отчетливо продемонстрировали положительное влияние терапии метформином на риск макрососудистой патологии у пациентов с сахарным диабетом 2 типа. Тем не менее, влияние метформина на развитие и прогрессирование одного из наиболее серьезных микрососудистых осложнений заболевания - диабетической нефропатии - не является столь однозначным и требует проведения исследований в этой области. Цель работы. В хроническом эксперименте на модели диабетической нефропатии при сахарном диабете 2 типа у крыс оценить влияние терапии метформином на морфофункциональное состояние почек. Материал и методы исследования. Половозрелым самцам крыс стока Wistar, подвергшимся правосторонней нефрэктомии с последующим переводом на 5 недель на высокожировое питание, через 11 недель после индукции никотинамид-стрептозотоцинового сахарного диабета 2 типа была назначена терапия метформином в дозе 300 мг/кг с питьевой водой или крахмал (группа контроля). Результаты исследования. Терапия метформином не оказывала значимого влияния на сывороточный креатинин, альбуминурию и клиренс креатинина, а также на выраженность морфологических изменений клубочков по окончании исследования на 30-й неделе. Однако, по сравнению с контрольной группой крыс с диабетом отмечалась тенденция к уменьшению морфологических проявлений поражения тубулоинтерстиция, а также значимое снижение экскреции с мочой молекулы почечного повреждения-1, которая рассматривается в качестве маркера поражения канальцев при сахарном диабете. Вывод. Проведенное экспериментальное исследование продемонстрировало способность метформина ослаблять канальцевые нарушения при развитии диабетической нефропатии в условиях экспериментального сахарного диабета 2 типа, что, безусловно, требует проведения дальнейших исследований в этой области, в том числе и с участием пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Introduction and purpose. A number of landmark trials have demonstrated clear benefits of metformin therapy in the prevention of macrovascular outcomes. Nevertheless, there is a lack of robust evidence to suggest whether metformin therapy will have similar beneficial outcomes in one of the most serious type 2 diabetes-related renal microvascular complications known as diabetic nephropathy. The study aimed to evaluate the effects of ten-week metformin treatment on renal morphofunctional changes in rats with non-genetic type 2 diabetic nephropathy. Materials and methods. Starting at 3 weeks after unilateral nephrectomy, adult male Wistar rats were fed the high-fat diet for 5 weeks, and then successively received nicotinamide (230 mg/kg) and streptozotocin (65 mg/kg) intraperitoneally in 15-min interval. Results. Starting at 11 weeks after confirmation of diabetes, metformin treatment did not attenuate routine renal dysfunction markers such as creatinine, creatinine clearance and albuminuria compared to placebo-treated diabetic group, and glomerulosclerosis index and glomerular expression of type IV collagen didn't significantly change either. Nevertheless, level of urinary kidney injury molecule-1, considered to be the marker of tubular damage in diabetes, was significantly lower in metformin-treated animals. Moreover, reduction of tubulointerstitial lesion tended to be significant. Conclusions. Under conditions of diabetic nephropathy modeling, metformin has shown direct protective effects against diabetic tubular disturbance. To assess long-term renal outcomes of these findings, more pre-clinical studies and clinical trials are required.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метформин</kwd><kwd>почки</kwd><kwd>крыса</kwd><kwd>сахарный диабет 2 типа</kwd><kwd>диабетическая нефропатия</kwd><kwd>metformin</kwd><kwd>kidney</kwd><kwd>rat</kwd><kwd>diabetes mellitus type 2</kwd><kwd>diabetic nephropathy</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">Бабенко А.Ю., Байрашева В.К.
