Ранее нами был описан клинический фенотип ОА в сочетании с СД 2 типа (ОАСД), являющийся субтипом ОА и характеризующийся большей тяжестью ОА, сниженным уровнем качества жизни. В настоящее время в литературе отсутствуют данные о биомаркерах ОАСД. Исходя из современных знаний о механизмах развития СД 2 типа и ОА, предполагается, что ключевым молекулярным звеном патогенеза этих заболеваний могут быть нарушения процессов метилирования ДНК. Ряд факторов (хроническое системное воспаление, повышение содержания конечных продуктов гликирования) может приводить к усилению деградации хряща при ОА, ассоциированном с СД 2 типа. Как ОА, так и СД 2 характеризуются высоким бременем коморбдной патологии, что позволяет предположить аддитивный эффект сочетания этих заболеваний на индексы коморбидности. Таким образом, в поисковом исследовании у больных ОАСД изучалось глобальное метилирование ДНК в мононуклеарах перифе-рической крови (МНК ПК), биомаркеры деструкции в хрящевой ткани и показатели коморбидности. Уровень глобального метилирования ДНК в МНК ПК оценивался как содержание 5-метилцитозина с помощью проточной цитометрии. Определение содержания аггрекана и антител к коллагену II типа в сыворотке ПК проводили методом ИФА. Показатели коморбидности оценивались с помощью шкалы CIRS-G (Cumulative Illness Rating Scale). Обследовано 78 больных генерализованным ОА. Опытную группу составили 52 больных, у которых клиническим проявлениям ОА не менее года предше-ствовал СД 2 типа. В контрольную группу были включены 26 больных ОА без СД. Установлено, что, помимо тяжелых клинических проявлений суставного синдрома и наличия системного воспаления, у больных ОАСД определяется высокий уровень тяжести коморбидности, обусловленный не только СД, но и другими сопутствующими заболеваниями. Различий по другим показателям коморбидности между сравниваемыми группами не выявлено. У пациентов с ОАСД также регистрируется увеличение содержания в сыворотке ПК аггрекана и антител к другому матриксному компоненту деструкции – коллагену II. Показано, что МНК ПК больных ОАСД и больных ОА без сопутствующего СД характеризуются более высоким, чем у здоровых людей, уровнем метилирования ДНК. Заключается, что дальнейшие исследования эпигенетической регуляции воспаления, метаболизма хрящевой ткани у больных ОА позволят идентифицировать новые терапевтические мишени и разработать более эффективные методы терапии не только основного, но и сопутствующих заболеваний.</p></abstract><trans-abstract xml:lang="en"><p>Osteoarthritis (OA) is among challenging problems of clinical medicine, not only due to its high prevalence, but also because of higher burden of comorbidities. Previously we described a clinical phenotype of OA associated with type 2 diabetes mellitus (OADM), which is one of OA phenotypes characterized by increased severity and reduced quality of life. In current literature, there is a lack of data on OADM biomarkers. Based on the current knowledge on type 2 DM and OA pathogenesis, it may be suggested that disturbances of DNA methylation may present the key pathogenetic mechanism for the both diseases. A number of factors, for example, chronic systemic inflammation, or increased levels of advanced glycation end products, may lead to increased articular cartilage degradation in type 2 DM-associated OA. Both OA and type 2 DM are characterized by higher comorbidity burden, thus allowing to suggest that coexistence of these diseases leads to additive effects upon comorbidity indices. In this exploratory study, we evaluated levels of total DNA methylation in peripheral blood mononuclear cells (PBMC), along with biomarkers of serum cartilage degradation and comorbidity features in patients with OA associated with diabetes (OADM). Global DNA methylation in PBMC was assessed as 5-methylcytosine levels using flow cytometry. Circulating aggrecan and anti-CII antibody concentrations were measured by means of ELISA. Comorbidity indices were assessed using Cummulative Illness Rating Scale (CIRS-G). A total of 78 patients with generalized OA were assessed. Fifty two patients had clinical manifestations of OA preceded by DM type II for 1 year (case group), and 26 OA patients were non-diabetic (control group). Patients with OADM had more pronounced joint impairment and higher severity of comorbidity. There were no differences in other measures of comorbidity between the compared groups. In conclusion, further studies on epigenetic control of inflammation and cartilage metabolism in patients with OA will enable to identify new therapeutic targets and to define new treatment strategies for the both basic disorder and comorbidity states. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>остеоартрит</kwd><kwd>сахарный диабет</kwd><kwd>метилирование ДНК</kwd><kwd>иммунная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteoarthritis</kwd><kwd>diabetes mellitus</kwd><kwd>DNA methylation</kwd><kwd>immune system</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">Анкудинов А.С.
