Отдельные исследования демонстрируют, что на формирование иммунных нарушений, которые являются триггерным механизмом развития РА, оказывает влияние комплекс неблагоприятных климато-географических факторов.</p><p>Цель – сравнительный анализ иммунологических показателей при РА у жителей различных регионов Узбекистана.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование были включены больные РА из трех регионов Узбекистана: г. Ташкента (I зона; n=25), Хорезмской области (II зона; n=25) и Наманганской области (III зона; n=28).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Сравнительный анализ иммунного статуса показал, что у пациентов, проживающих во II зоне, отмечается достоверное снижение Т-клеточного иммунного ответа (р&lt;0,05), значительное увеличение числа Вμ-лимфоцитов (р&lt;0,001) и достоверно более низкое содержание CD11b+, CD18+, CD25+ и СD95+ клеток (р&lt;0,05), чем у больных двух других зон. Изучение частоты мономорфной детерминанты антигенов гистосовместимости I класса (HLA-I) выявило ее достоверное снижение у больных, проживающих в I и III зонах (р&lt;0,05), тогда как у больных РА из II зоны была достоверно повышена частота HLA-DR (р&lt;0,05).</p><p>Таким образом, сравнительный анализ показывает, что иммунологические показатели у больных РА в трех зонах Узбекистана различаются, что позволяет говорить о возможном влиянии климато-географических факторов внешней среды на течение заболевания. </p></sec></abstract><trans-abstract xml:lang="en"><p>The feature of rheumatoid arthritis (RA) is the predominant clinical picture of chronic synovial joint inflammation accompanied by progressive cartilage and bone destruction, the pathogenesis of which is greatly due to autoimmune mechanisms. Some investigations demonstrate that a set of poor climatic and geographical factors may influence the development of immune disorders that are a trigger in the development of RA.</p><sec><title>Objective</title><p>Objective: to comparative analyze immunological parameters in RA in dwellers from different regions of Uzbekistan.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. The study enrolled RA patients from three Uzbekistan zones: 1) Tashkent (n = 25), 2) Xorazm Region (n = 25); 3) Namangan Region (n = 28).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Comparative analysis of the immune status indicated that the patients living in Zone 2 exhibited a significantly reduced T cell immune response (p &lt; 0.05), a considerably higher count of B lymphocytes (p &lt; 0.001), and significantly lower levels of CD11b+, CD18+, CD25+, and CD95+ cells (p &lt; 0.05) than did those from the two other zones. Examination of the frequency of the monomorphic determinant of histocompatibility Class I (HLA-I) antigens revealed its significant decrease in the patients residing in Zones 1 and 3 (p &lt; 0.05) whereas the RA patients from Zone 2 had a significantly higher frequency of HLA-DR (p &lt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. The comparative analysis shows that the immunological parameters differ in the patients from the three zones of Uzbekistan, which may suggest that the climatic and geographical factors of the environment may influence the course of the disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>иммунный статус</kwd><kwd>географические зоны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>immune status</kwd><kwd>geographical zones</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">Насонова ВА, Лукина ГВ, Сигидин ЯА.
