Становится актуальным изучение формирования гуморального противовирусного иммунитета у лиц, перенесших заболевание и привитых от SARS-CoV-2 вируса. В работе определяли сывороточные уровни биомаркеров воспаления и цитокинового шторма (прокальцитонина, sCD14, sLBP, sTREM1, IL-6, IL-8, IL-10, sWnt5a, TNFα и TNFβ) методом иммуноферментного анализа. Изучали связь между содержанием биомаркеров в сыворотке крови лиц с низкими и высокими концентрациями противовирусных антител, косвенными показателями которых являются значения коэффициента позитивности (КП). Установлено достоверное увеличение сывороточного содержания sTREM1, IL-6 и прокальцитонина у лиц с высоким уровнем КП, перенесших инфекцию. Выявлено достоверное увеличение IL-6 и прокальцитонина у лиц, привитых вакциной Спутник V, как с низким уровнем КП, так и с высоким. У привитых лиц с низким уровнем КП также наблюдалось достоверное увеличение содержания sTREM1. Показано, что содержание sCD14 (пресепсина) достоверно ниже у вакцинированных лиц как с низким, так и с высоким КП по сравнению с донорами. При изучении корреляционных связей между КП и сывороточным содержанием биомаркеров у вакцинированных лиц выявлена слабая обратная корреляция для sLBP (r = –0,465) и IL-6 (r = –0,437), а также средняя обратная корреляция для sTREM1 (r = –0,508).</p></abstract><trans-abstract xml:lang="en"><p> COVID-19 has become a planetary emergency which is seriously threatening human health. Comparative studies can shed light on the molecular mechanisms of the formation of humoral antiviral immunity in persons who have undergone the disease and have been vaccinated against the SARS-CoV-2 virus. Serum levels of biomarkers of inflammation and cytokine storm (procalcitonin, sCD14, sLBP, sTREM1, IL-6, IL-8, IL-10, sWnt5a, TNFα and TNFβ) were determined by enzyme immunoassay. We studied the relationship between the content of biomarkers in blood serum with low and high concentrations of antiviral antibodies, indirect indicators of which are the values of the positivity coefficient (CP). A significant increase in the serum levels of sTREM1, IL-6, and procalcitonin was found in persons with a high CP level after infection. A significant increase in IL-6 and PCT was revealed in persons vaccinated with the Sputnik V vaccine, both with a low level of CP and with a high one. In vaccinated individuals with a low CP level, a significant increase in the sTREM1 content was also observed. It has been shown that the content of sCD14 (presepsin) is significantly lower in vaccinated individuals, both with low and high CP, compared with donors. When studying the correlations between CP and serum biomarkers in vaccinated individuals, a weak inverse correlation was found for sLBP (r = –0.465) and IL-6 (r = –0.437), as well as an average inverse correlation for sTREM1 (r = –0.508).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>биомаркеры воспаления</kwd><kwd>маркеры цитокинового шторма</kwd><kwd>коэффициент позитивности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>inflammation biomarkers</kwd><kwd>cytokine storm markers</kwd><kwd>coefficient of positivity</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">Титов, Л.
