За это время обнаружено, что часть клинических проявлений болезни однотипно ассоциируется с заболеванием практически во всех популяциях, а другая часть зависит от этнической принадлежности пациентов. Также периодически описываются уникальные взаимосвязи, характерные только для отдельных этнических групп.</p><p>   Цель исследования – проанализировать клинические характеристики стационарного контингента больных АС в зависимости от статуса HLA-B27.</p><sec><title>   Материал и методы</title><p>   Материал и методы. Проведено одномоментное исследование 200 последовательно поступивших в ревматологическое отделение ФГБНУ «Научно-исследовательский институт ревматологии им. В. А. Насоновой» больных АС. Всем пациентам выполнено стандартное клиническое обследование, рекомендованное для оценки активности и функционального статуса при АС. Изучалось также содержание трансаминаз, мочевой кислоты, мочевины, креатинина, интерлейкина (ИЛ) 6 и ИЛ17 в сыворотке крови.</p><p>   Результаты и обсуждение. HLA-В27 обнаружен у 166 (83 %) из 200 пациентов с АС (у 89,8 % мужчин и 73,2 % женщин; р = 0,003). Среди HLA-B27-позитивных больных АС было 63,9 % мужчин, а среди HLA-B27 негативных – 35,3 % (р = 0,002). Средний возраст дебюта АС у HLA-B27-негативных больных был на 5 лет больше, ювенильное начало болезни у них встречалось примерно в 2 раза реже. У 25 % больных, позитивных HLA-B27, и 15 % больных, не имевших этого антигена, выявлены синдесмофиты (p &gt; 0,05). Они обнаружены у 31,1 % HLA-B27-позитивных и 25 % HLA-B27-негативных мужчин. У женщин при наличии HLA-В27 синдесмофиты встречались в 15 %, а при его отсутствии – в 9 % случаев (р = 0,022). У HLA-В27 негативных больных чаще отмечались воспалительные заболевания кишечника, реже – увеит и псориаз. Показатели активности, частота артрита и энтезита у позитивных и негативных по HLA-B27 больных были сходными. Концентрация ИЛ17 в сыворотке у HLA-B27-негативных больных была в 6 раз выше, чем у HLA-B27-позитивных (p = 0,012).</p></sec><sec><title>   Заключение</title><p>   Заключение. В российской популяции больных АС имеются характерные для большинства этносов ассоциации с HLA-B27 (например, более раннее начало болезни) и ассоциации, которые встречаются не во всех этнических группах (например, более тяжелое течение, более высокая частота артрита и энтезита). Кроме того, концентрация ИЛ17 в сыворотке крови у HLA-В27- негативных больных была в 6 раз выше, чем у HLA-В27-позитивных. Это может указывать на неканонические механизмы патогенеза АС, развивающегося при отсутствии гена HLA-B27, что требует дальнейших исследований.</p></sec></abstract><trans-abstract xml:lang="en"><p>   The link between the HLA-B27 gene and ankylosing spondylitis (AS) has been known for almost 50 years. During this time, it has been discovered that some of the clinical manifestations of the disease are uniformly associated with the disease in almost all populations, while the other part depends on the ethnicity of the patients. Unique associations characteristic only of certain ethnic groups are also periodically described.</p><sec><title>   Objective</title><p>   Objective: to analyze the clinical features of the inpatient population with AS in relation to their HLA-B27 status.</p></sec><sec><title>   Material and methods</title><p>   Material and methods. Cross sectional study of 200 consecutive AS patients admitted to the rheumatology department of the V.A. Nasonova Research Institute of Rheumatology. All patients underwent standard clinical examination recommended for assessment of AS activity and functional status. The levels of transaminases, uric acid, urea, creatinine, interleukin (IL) 6 and IL17 in blood serum were also examined.</p><p>   Results and discussion. HLA-B27 was detected in 166 (83 %) of 200 patients with AS (in 89.8 % of men and in 73.2 % of women; p = 0.003). Among HLA-B27 positive patients with AS, 63.9 % were men, and among HLA-B27 negative patients, 35.3 % were men (p = 0.002). The mean age of AS onset was 5 years higher in HLA-B27-negative patients, and the disease was about 2 times less likely to occur in childhood in them. Syndesmophytes were detected in 25 % of HLA-B27 positive patients and in 15 % of patients who did not have this antigen (p &gt; 0.05). Syndesmophytes were found in 31.1 % of HLA-B27 positive and 25 % of HLA-B27 negative men. 15 % of women with HLA-B27 and 9 % of women without this antigen had syndesmophytes (p = 0.022). Inflammatory bowel disease was more common in HLA-B27-negative patients, whereas uveitis and psoriasis were less common. Activity rates and incidence of arthritis and enthesitis were similar in HLA-B27 positive and negative patients. Serum concentration of IL17 was six times higher in HLA-B27 negative patients than in HLA-B27 positive patients (p = 0.012).</p></sec><sec><title>   Conclusion</title><p>   Conclusion. In the Russia’s AS patient population there are associations with HLA-B27, characteristic for most ethnic groups (e. g., earlier onset of the disease) and associations not found in all ethnic groups (e. g., a more severe course, a higher incidence of arthritis and enthesitis). In addition, the concentration of IL17 in the blood serum of HLA-B27 negative patients was six times higher than that of HLA-B27 positive patients. This may indicate non-canonical mechanisms of pathogenesis of AS that develop in the absence of the HLA-B27 gene, which requires further research.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>анкилозирующий спондилит</kwd><kwd>HLA-B27</kwd><kwd>интерлейкин 17</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ankylosing spondylitis</kwd><kwd>HLA-B27</kwd><kwd>interleukin 17</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках фундаментального научного исследования № АААА-А19-1021051503111-9.
