В клинической практике всё чаще стали встречаться случаи сочетанного течения двух и более иммунологических заболеваний, что называют термином «overlap-синдром» или «синдром перекрёста». До сих пор отсутствуют данные о конкретных причинах развития overlap-синдрома, среди наиболее вероятных версий является сочетание генетических изменений, в том числе разнообразия аллелей human leukocyte antigen (HLA), с триггерными факторами извне. Особенности данного синдрома заключаются в трудностях дифференциально-диагностического поиска из-за многообразия симптомов. Несвоевременная верификация диагноза приводит к позднему назначению лечения и менее благоприятному отдалённому прогнозу. В клинической практике наиболее часто встречается сочетание системной склеродермии или системной красной волчанки с ревматоидным артритом. В данной статье приводится пример overlap-синдрома у пациентки 69 лет с тремя аутоиммунными патологиями — системная склеродермия, синдром Шегрена (СШ) и первичный билиарный холангит с полиорганным поражением (лёгкие, кожа, желудочно-кишечный тракт, слюнные железы, сосуды, нервная система). Пациентка имела длительный анамнез синдрома Рейно, а также первичного билиарного холангита. За 2 года до обращения у пациентки был диагностирован синдром Шегрена, в 2025 году — лимитированная форма системной склеродермии. Таким образом, у пациентки в течение жизни развились сразу 3 аутоиммунные патологии, включенные в overlap-синдром. Специалистам следует проявлять повышенное внимание к пациентам с длительным анамнезом ревматологического заболевания для своевременного выявления других аутоиммунных патологий и начала своевременного лечения для предотвращения развития осложнений.</p></abstract><trans-abstract xml:lang="en"><p>The improvement of diagnostic methods and the possibilities of modern medicine lead to a deeper study of autoimmune pathology. In clinical practice, cases of a combined course of two or more immunological diseases have become increasingly common, which is called the term “overlap-syndrome” or “crossroads syndrome”. There is still no data on the specific causes of the overlap-syndrome, among the most likely versions is a combination of genetic changes, including the diversity of human leukocyte antigen (HLA) alleles, with external trigger factors. The features of this syndrome are the difficulties of differential diagnostic search due to the variety of symptoms. Untimely verification of the diagnosis leads to a late appointment of treatment and a less favorable long-term prognosis. In clinical practice, a combination of systemic scleroderma or systemic lupus erythematosus with rheumatoid arthritis is most common. This article provides an example of the overlap-syndrome in a 69–year-old patient with three autoimmune pathologies — systemic scleroderma, CABG, and primary biliary cholangitis with multiple organ damage (lungs, skin, gastrointestinal tract, salivary glands, blood vessels, and nervous system). The patient had a long history of Raynaud’s syndrome, as well as primary biliary cholangitis. Two years before the treatment, the patient was diagnosed with Sjogren’s syndrome, and in 2025, a limited form of systemic scleroderma. Thus, during her lifetime, the patient developed 3 autoimmune pathologies included in the overlap-syndrome. Specialists should pay increased attention to patients with a long history of rheumatological disease in order to detect other autoimmune pathologies in a timely manner and initiate timely treatment to prevent the development of complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>overlap-синдром</kwd><kwd>синдром перекреста</kwd><kwd>системная склеродермия</kwd><kwd>синдром Шегрена</kwd><kwd>первичный билиарный холангит</kwd><kwd>прогрессирующий системный склероз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>overlap-syndrome</kwd><kwd>systemic scleroderma</kwd><kwd>Sjogren’s syndrome</kwd><kwd>primary biliary cholangitis</kwd><kwd>progressive systemic sclerosis</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">Бабаева А.Р., Калинина Е.В., Звоноренко Д.С., и др.
