Факторы роста (ФР) играют одну из ведущих ролей в заживлении ран. Их дефицит при синдроме диабетической стопы продемонстрирован в экспериментальных работах, в большинстве своем выполненных на острых ранах. При этом в настоящее время эффективность местной терапии ФР этой категории больных, а также показания и противопоказания к ней противоречивы и являются предметом для дискуссии. Данных о содержании ФР в язвенных дефектах при синдроме диабетической стопы различной длительности нет. Между тем полученные результаты помогут расширить представление о патогенетических механизмах течения и исходов хронических язвенных дефектов при синдроме диабетической стопы, находящихся на разных стадиях заживления.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Проведение сравнительного анализа экспрессии ФР и рецепторов к ним в хронических незаживающих язвенных дефектах разной длительности при синдроме диабетической стопы.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Исследовались 89 образцов нейропатических язвенных дефектов. Иммуногистохимический анализ биоптатов выполнялся при помощи антител к следующим ФР и их рецепторам: сосудистый эндотелиальный ФР (СЭФР), инсулиноподобный ФР (ИФР), эпидермальный ФР (ЭФР). В зависимости от длительности существования раны биоптаты были разделены на 3 группы: группа 1 — ≤90 дней, группа 2 — 91-365 дней, группа 3 — &gt;365 дней.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. В образцах ран, длительность которых не превышала 90 дней, экспрессия ФР и рецепторов к ним была значимо выше, чем в ранах большей длительности (p=0,0001). Значимой разницы в количественных показателях экспрессии ФР и рецепторов к ним между ранами длительностью от 91 до 365 дней и более 365 дней не получено. Согласно данным корреляционного анализа, экспрессия СЭФР, ИФР, ЭФР и рецепторов к ним имеет значимую отрицательную зависимость от длительности существования раны (p=0,0001).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. В язвенных дефектах при нейропатической форме синдрома диабетической стопы длительностью ≤90 дней экспрессия таких ФР, как СЭФР, ИФР, ЭФР, и рецепторов к ним статистически значимо выше, чем в ранах большей длительности. Выявлена зависимость экспрессии ФР от длительности существования язвенного дефекта. Полученные данные могут объяснять различия в исходах течения хронических ран и отсутствие в ряде случаев эффекта от местной терапии ФР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND. Growth factors play a leading role in wound healing. Their deficiency in diabetic foot syndrome has been demonstrated in experimental studies, most of them performed on acute wounds. At the same time, currently the effectiveness of local therapy with growth factors of this category of patients, as well as indications and contraindications to it are contradictory and are a subject for discussion. There is no data on the content of growth factors in diabetic foot ulcers of various durations. Meanwhile, the results obtained will help to expand the understanding of the pathogenetic mechanisms of the course and outcomes of diabetic foot ulcers at different stages of healing.</p></sec><sec><title>AIM</title><p>AIM: To evaluate the level of growth factors and their receptors in non-healing neuropathic diabetic foot ulcers of different duration.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS. 89 samples of neuropathic diabetic foot ulcers were examined. Immunohistochemical analysis of biopsies was performed using antibodies to the following growth factors and their receptors: vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), epidermal growth factor (EGF). Depending on the duration of the wound, the biopsies were divided into 3 groups: group 1 — ≤ 90 days, group 2 — 91-365 days, group 3 — &gt; 365 days.</p></sec><sec><title>RESULTS</title><p>RESULTS. In the samples of wounds, the duration of which did not exceed 90 days, the expression of growth factors and receptors to them was significantly higher than in wounds of longer duration (p=0.0001). There was no significant difference in quantitative indicators of the expression of growth factors and their receptors between wounds lasting from 91 to 365 days and more than 365 days. According to the data of correlation analysis, the expression of VEGF, IGF, EGF and their receptors has a significant negative dependence on the duration of the wound (p= 0.0001).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. In diabetic foot ulcers lasting less than 90 days, the expression of growth factors such as VEGF, IGF, EGF and their receptors is significantly higher than in wounds of longer duration. The dependence of the expression of growth factors on the duration of the ulcer was revealed. The data obtained may explain the differences in the outcomes of chronic wounds and the absence in some cases of the effect of local therapy with growth factors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром диабетической стопы</kwd><kwd>незаживающие язвенные дефекты</kwd><kwd>факторы роста</kwd><kwd>сосудистый эндотелиальный фактор роста</kwd><kwd>инсулиноподобный фактор роста</kwd><kwd>эпидермальный фактор роста</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetic foot syndrome</kwd><kwd>heard to heal ulcers</kwd><kwd>growth factors</kwd><kwd>vascular endothelial growth factor</kwd><kwd>insulin-like growth factor</kwd><kwd>epidermal growth factor</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">Blakytny R, Jude E.
