The first group — with the diagnosed of focal infection (18 people), the second group — without the presence of focal infection (12 people). The control group consisted of 15 healthy individuals admitted to the clinic for the removal of benign skin tumors. All patients underwent a comprehensive clinical, instrumental and laboratory examination, as well as an immunogram. Determination of lymphocyte subpopulations was carried out on a flow cytometer “Cytom - ics FC500” by Beckman Coulter using various combinations of direct monoclonal antibodies and isotopic controls. The groups were compared using nonparametric Mann — Whitney test, the differences were considered significant at p &lt; 0.05.</p><p><bold>Results.</bold> The absence of significant quantitative changes in the main and small subpopulations of T- and В-lymphocytes in both groups of patients with psoriasis was shown. At the same time, the group of patients with psoriasis and focal infection, was characterized by an increase in the relative number of T-lymphocytes (p = 0.034) and T-helpers (p = 0.012), the relative and absolute number of activated CD3+HLA-DR+cells (p = 0.028 and 0.036, respectively), as well as a decrease in regulatory T-helper (p = 0.031). Subpopulation of CLA+CD3+-lymphocytes tropic to the skin in comparison with control was increased both in the first (p = 0.016) and second (p = 0.044) groups. Also, patients with psoriasis differed from healthy individuals by increasing the number of memory T-cells (p = 0.049 for group 1, p = 0.003 for group 2).</p><p><bold>Conclusion.</bold> Existing focal infection in psoriasis patients lead to an imbalance in the content of individual lymphocyte subpopulations: an increase in the relative number of CD3+CD4+ and CD3+HLA-DR+ cells, as well as a decrease in regulatory T-helper. These changes can lead to a long course of the disease and a reduction in remission periods.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования:</bold> изучить влияние очагов хронической инфекции (ОХИ) на иммунный статус больных псориазом.</p><p><bold>Материалы и методы.</bold> Обследованы 30 больных псориазом в возрасте от 19 до 61 года (у 21 человека диагностирован бляшечный псориаз, у 9 — каплевидный псориаз), которые были разделены на 2 группы. В первую группу вошли больные с выявленными очагами хронической инфекции (18 человек), во вторую — без наличия очагов хронической инфекции (12 человек). Группу контроля составили 15 практически здоровых лиц, поступивших в клинику для удаления доброкачественных новообразований кожи. Всем пациентам проведено комплексное клиническое, инструментальное и лабораторное обследование, а также выполнена иммунограмма. Определение субпопуляций лимфоцитов проводилось на проточном цитометре Cytomics FC500 фирмы Beckman Coulter с использованием различных комбинаций прямых моноклональных антител и изотопических контролей. Сравнение групп проводили с использованием непараметрического критерия Манна — Уитни, различия считали значимыми при p &lt; 0,05.</p><p><bold>Результаты.</bold> Показано отсутствие выраженных количественных изменений со стороны основных и малых субпопуляций Т- и В-лимфоцитов в обеих группах больных псориазом. В то же время группа больных псориазом, имеющих ОХИ, отличалась повышением относительного количества Т-лимфоцитов (p = 0,034) и Т-хелперов (p = 0,012), относительного и абсолютного количества активированных CD3+HLA-DR+-клеток (p = 0,028 и 0,036 соответственно), а также уменьшением регуляторных T-хелперных клеток (p = 0,031). Субпопуляция тропных к коже CLA+CD3+-лимфоцитов в сравнении с контролем была повышена как в первой (p = 0,016), так и во второй (p = 0,044) группах. Также больные псориазом отличались от практически здоровых лиц повышением количества Т-клеток памяти (p = 0,049 для 1-й группы, p = 0,003 для 2-й группы).</p><p><bold>Заключение.</bold> Существующие очаги хронической инфекции у больных псориазом приводят к дисбалансу в содержании отдельных субпопуляций лимфоцитов: повышению относительного количества CD3+CD4+ и CD3+HLA-DR+ клеток, а также уменьшению регуляторных Т-хелперных клеток. Данные изменения могут приводить к длительному течению заболевания и сокращению периодов ремиссии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>psoriasis</kwd><kwd>chronic tonsillitis</kwd><kwd>apical periodontitis</kwd><kwd>focal infection</kwd><kwd>immunological examination</kwd><kwd>immunogram</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>псориаз</kwd><kwd>хронический тонзиллит</kwd><kwd>хронический периодонтит</kwd><kwd>очаги хронической инфекции</kwd><kwd>иммунологическое обследование</kwd><kwd>иммунограмма</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
