Процессы заживления ран нижних конечностей замедлены при сахарном диабете (СД). В различных исследованиях показана роль контроля диабета, цитокинов и факторов роста в этих процессах. Однако роль генов, определяющих пролиферацию клеток, синтез коллагена, формирование здоровой грануляционной ткани, остается малоизученной.</p></sec><sec><title>Цель</title><p>Цель. Изучить особенности экспрессии генов коллагенов на различных фазах раневого процесса у лиц с нейропатической формой синдрома диабетической стопы (СДС).</p></sec><sec><title>Методы</title><p>Методы. В проспективное исследование включены 4 больных с нейропатической формой СДС после проведенной хирургической обработки, у которых были взяты образцы тканей для морфологического и генетического исследования на 0, 10 и 15-е сутки местного лечения с целью оценки экспрессии генов коллагенов COL1A1, COL1A2, COL3A1. Стадия раневого процесса оценивалась по гистологической картине.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе исследования подтверждено, что размер ран включенных в исследование больных уменьшился на 8,8±7% через 10 дней местного лечения и на 18,3±8% через 15 дней терапии. Согласно данным гистологического исследования биоптатов раневого ложа, через 10 дней у всех больных отмечалась тенденция к уменьшению воспалительного инфильтрата, к нарастанию количества фибробластоподобных клеток, фиксировалось наличие созревающей грануляционной ткани и появление формирующихся волокон соединительной ткани. Однако через 15 дней в тканях всех пациентов обнаружена сохраняющаяся воспалительная инфильтрация, несмотря на формирование зрелой грануляционной ткани. По результатам генетического исследования на 10-е сутки местного лечения ран выявлена тенденция к увеличению экспрессии гена COL1A1 в 3,2±1,3 раза, экспрессии гена COL1A2 в среднем в 2,0±1,0 раз, а экспрессии гена COL3A1 – в 1,25±1,1 раза по сравнению с исходными показателями. На 15-е сутки местного лечения отмечается тенденция к снижению экспрессии генов COL1A1 и COL1A2: по сравнению с исходными данными экспрессия COL1A1 снизилась в 1,7±0,6 раза, а экспрессия генов COL1A2 и COL3A1 уменьшилась в 2,5±2 раза и в 20,0±3 раза соответственно.</p></sec><sec><title>Заключение</title><p>Заключение. Экспрессия генов коллагенов (COL1A1, COL1A2, COL3A1) более выражена в фазу пролиферации и снижается к ее окончанию, что подтверждается клинической картиной и данными морфологического исследования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Tissue repair processes are impaired in diabetic foot ulcers (DFUs). Previous research has shown that glycaemic control, cytokines and growth factors play an important role in wound healing. Emerging evidence also suggests that genes play a role via their regulation of cell proliferation, collagen synthesis and granulation tissue formation.</p></sec><sec><title>Aim</title><p>Aim. To evaluate collagen genes expression in different stages of wound healing in patients with DFUs.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Prospective study included four patients with neuropathic DFUs after surgical debridement. Tissue samples were taken for morphological and genetic tests on days 0, 10 and 15 of local treatment to evaluate expression of collagen genes (i.e. COL1A1, COL1A2, COL3A1) and to perform morphological tests.</p></sec><sec><title>Results</title><p>Results. The present study confirmed that the size of wounds decreased by 8.8 ± 7% after 10 days of local treatment and by 18.3 ± 8% after 15 days of local treatment. According to histological examination of wound biopsies at day 10, all patients showed a tendency for lower levels of inflammatory infiltrate, increased number of fibroblast-like cells, presence of maturing granulation tissue and emergence of connective tissue fibres. After 15 days, we detected inflammatory infiltration in the wounds, despite the formation of mature granulation tissue. According to results of genetic analysis on day 10 of local wound treatment, we found a tendency for increased expression of collagen genes relative to the baseline: COL1A1 increased by 3.2 ± 1.3 times, COL1A2 by 2.0 ± 1.0 times and COL3A1 by 1.25 ± 1.1 times. On day 15 of local treatment, in contrast, we found a tendency for decreased expression of COL1A1, COL1A2 and COL3A1 relative to the baseline (1.7 ± 0.6, 2.5 ± 2 and 20.0 ± 3 times, respectively).</p></sec><sec><title>Conclusions</title><p>Conclusions. The expression of collagen genes (COL1A1, COL1A2, COL3A1) is more pronounced in proliferation phase and is subsequently reduced towards the end. These data were confirmed by morphological study and clinical pictures.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет</kwd><kwd>раны</kwd><kwd>СДС</kwd><kwd>репарация</kwd><kwd>гены</kwd><kwd>экспрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diabetes mellitus</kwd><kwd>wounds</kwd><kwd>DFUs</kwd><kwd>repair</kwd><kwd>genes</kwd><kwd>expression</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.
