Оценить состояние системной воспалительной реакции и гуморального иммунного ответа у пациентов среднего возраста, перенесших инфекцию COVID-19 легкой и средней степени тяжести.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. За период 2022–2023 гг. было проведено когортное одноцентровое исследование с участием 83 пациентов, перенесших инфекцию COVID-19 легкой и средней степени тяжести (женщины – 69,9 % (58 чел.), мужчины – 30,1 % (25 чел.)); медиана возраста – 53 года [49; 56]. Всем пациентам были выполнены клиническое исследование, оценка гуморального ответа с определением антител IgG и IgM к вирусу SARS-CoV-2, а также концентрации интерлейкинов: интерлейкина-1β, интерлейкина-4, интерлейкина-6, интерлейкина-8, интерлейкина-10, высокочувствительного С-реактивного белка, фактора некроза опухоли α, трансформирующего фактора роста β1 и прокальцитонина. Пациенты были разделены на три группы: 1–3 месяца после заболевания, 3–6 месяцев и 6 месяцев – 1 год.</p></sec><sec><title>   Результаты</title><p>   Результаты. Во всех группах пациентов в течение года процент лиц с положительным уровнем IgM составил около четверти (25, 21 и 25 % соответственно). При сохранении в пределах референсных значений в целом по группе в когорте пациентов с положительным уровнем IgM показатель прокальцитонина и интерлейкина-10 превышал значения таковых для когорты с отрицательным тестом (р = 0,0053 и р = 0,0044 соответственно), что было расценено нами как сохраняющееся хроническое компенсированное воспаление.</p></sec><sec><title>   Заключение</title><p>   Заключение. У четверти пациентов после перенесенной инфекции COVID-19 легкой и средней степени тяжести в течение года сохраняется стабильно положительный уровень IgM, сочетающийся с провоспалительным статусом по данным параметров системной воспалительной реакции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Objective</title><p>   Objective. To assess the state of the systemic inflammatory response and humoral immune response in middle-aged patients came through COVID-19 infection in mild and moderate severity.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. A cohort single-center study involving 83 patients came through COVID-19 infection in mild and moderate severity (women - 69.9% (58 patients), men - 30.1% (25 patients); median age 53 years [49; 56] was conducted over the period 2022-2023. All patients underwent clinical examination, evaluation of humoral response with determination of IgG and IgM antibodies to SARS-CoV-2 virus, as well as concentration of interleukins: interleukin-1β, interleukin-4, interleukin-6, interleukin-8, interleukin-10, high-sensitivity C-reactive protein, tumour necrosis factor α, transforming growth factor β1 and procalcitonin concentrations. Patients were divided into three groups: 1-3 months; 3-6 months; and 6 months to 1 year after COVID-19 infection.</p></sec><sec><title>   Results</title><p>   Results. Within a year the percentage of IgM-positive patients in all patient groups was about a quarter (25 %, 21 % and 25 % respectively). While remaining within the reference values for the whole group, procalcitonin and interleukin-10 levels in the selected cohort exceeded those of the test-negative cohort (p = 0.0053 and p = 0.0044, respectively), which we considered as persistent chronic compensated inflammation.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. A quarter of patients who came through COVID-19 infection in mild and moderate severity have persistently positive IgM levels for a year, combined with proinflammatory status according to systemic inflammatory response parameters.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>последствия инфекции COVID-19</kwd><kwd>гуморальный иммунный ответ</kwd><kwd>системная воспалительная реакция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>consequences of COVID-19 infection</kwd><kwd>humoral immune response</kwd><kwd>systemic inflammatory response</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнялась в рамках проекта НИР «Разработать алгоритм прогнозирования пост-COVID-19 ассоциированной патологии на основании изучения клинико-лабораторных и функциональных показателей», ГПНИ 4 «Трансляционная медицина», подпрограмма 4.2 «Фундаментальные аспекты медицинской науки».
