Известно, что процессы заживления при сахарном диабете замедлены. В связи с этим ведется активный поиск возможных причин снижения темпов репарации. Несмотря на уже имеющиеся данные, определение возможных маркеров активности репаративных процессов при сахарном диабете остается актуальным.</p></sec><sec><title>Цель</title><p>Цель. Изучить клинические, морфологические и некоторые иммуногистохимические показатели репарации мягких тканей нижних конечностей у пациентов с синдромом диабетической стопы на фоне местного лечения.</p></sec><sec><title>Методы</title><p>Методы. Обследовано 70 пациентов с синдромом диабетической стопы до и после хирургической обработки хронических раневых дефектов. Проанализированы клинические, гистологические (световая микроскопия) и иммуногистохимические (CD68, матриксные металлопротеиназы (MMP-9), тканевые ингибиторы металлопротеаз (TIMP-1)) характеристики тканевой репарации. Гистологическое и иммуногистохимическое исследования выполнены у 63 пациентов до и после хирургической обработки, через 10 дней после проводимого местного лечения.</p></sec><sec><title>Результаты</title><p>Результаты. На фоне лечения зафиксировано значимое уменьшение площади ран на 23,4% (p&lt;0,05), глубины ран на 29,4% (p&lt;0,05). Морфологическое исследование подтвердило формирование здоровой грануляционной ткани. Иммуногистохимическое исследование продемонстрировало значимое снижение протеолитической активности, что выразилось в снижении экспрессии MMP-9 (р&lt;0,05); статистически значимого изменения количества макрофагов на фоне местного лечения раны, а также повышения экспрессии TIMP-1 отмечено не было (p&gt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Клиническими показателями эффективности местного лечения раневых дефектов является значимое уменьшение площади и глубины ран, что было отмечено по результатам проведенного исследования. Интенсификация процесса заживления подтверждена результатами гистологического и иммуногистохимического исследований, однако отсутствие статистически значимого изменения количества макрофагов позволяет предположить, что именно это звено репарации нарушается при сахарном диабете и является причиной «хронизации» ран, что, безусловно, требует дальнейших исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: It is known that wound healing is Impaired in diabetes mellitus. Possible reasons are widely being searched. However, despite all the available data, reliable markers of reparative processes in diabetes mellitus are needed to be found.</p></sec><sec><title>Aim</title><p>Aim: To study morphological and some immunohistochemical markers of tissue repair in patients with diabetic foot ulcers after local treatment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: 70 patients with diabetic foot ulcers before and after surgical debridement were included. Histological (light microscopy) and immunohistochemical (CD68, MMP-9, TIMP-1) characteristics of tissue repair processes in soft tissues of the lower extremities in patients with diabetes mellitus were analyzed. Histological and immunohistochemical examination of soft tissues were performed in 63 patients before and after surgical debridement and 10 days after local treatment.</p></sec><sec><title>Results</title><p>Results: After the surgical debridement a significant reduction in the area of wounds was registered by 23.4% (p &lt;0.05), wound depth by 29.4% (p &lt;0.05). Based on the results of the morphological study, the presence of mature granulation tissue in the wounds was confirmed. Immunohistochemical study of wound biopsies demonstrated a significant decrease in proteolytic activity in the wound as a decrease in MMP-9 expression (p &lt;0.05). Statistically significant changes in the number of macrophages against the initial data were not found, as well as increased expression of TIMP-1 was observed (p&gt; 0.05 and &lt;0.05, respectively).</p></sec><sec><title>Conclusion</title><p>Conclusion: According to the data, there was a significant decrease in the area and depth of wounds during local treatment. The intensity of tissue repair was confirmed by the results of histological and immunohistochemical studies. However, the absence of a statistically significant change in the amount of macrophages on the background of treatment suggests that this repair link is disrupted in diabetes mellitus, which is the reason for the "chronic" wounds and requires further studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет</kwd><kwd>хронические раны</kwd><kwd>репарация</kwd><kwd>маркеры</kwd><kwd>гистология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetes mellitus</kwd><kwd>chronic wounds</kwd><kwd>repair</kwd><kwd>immunohistochemical markers</kwd><kwd>histology</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">Singh N, Armstrong DG, Lipsky BA.
