Исследование врождённого иммунного ответа человека к клещевым инфекциям после подтверждённого факта укуса заражённым клещом на ранних, скрытых доклинических стадиях может показать реакцию организма человека и будет способствовать разработке новых способов ранней диагностики и профилактики трансмиссивных заболеваний. Материал и методы. Всего на заражённость вирусом клещевого энцефалита, B. burgdorferi sensu lato, A. phagocytophilum и E. chaffeensis / E. muris проанализирован 2821 образец крови от людей, пострадавших от присасывания иксодовых клещей. 1421 проба проанализирована на наличие антител к клещевым инфекциям. В заражённых образцах крови с помощью иммуноферментного анализа определена концентрация основных цитокинов. Результаты и обсуждение. Установлена инфицированность людей после присасываний клещей: 3,2 % - антиген вируса клещевого энцефалита; 1,8 % - РНК вируса клещевого энцефалита; 4,1 % - B. burgdorferi sensu lato; 0,45 % - A. phagocytophilum; 0,15 % - E. chaffeensis / E. muris. Показано, что бактериальные патогены, особенно B. burgdorferi sensu lato и A. phagocytophilum, индуцируют очень похожие профили врождённого иммунного ответа человека. Для этих микроорганизмов характерна активация IL-1a, IL-8 и IFN-a и подавление синтеза SOD, IL-1Ra и IL-17A. Инфекция ВКЭ на ранней стадии индуцирует своеобразный профиль цитокинового ответа у заражённого человека. Для вирусной инфекции характерно возрастание концентрации IL-1a, IL-8, IL-10, IL-17A, интерферона IFN-y и, в отличие от бактериальных инфекций, SOD. Некоторое подавление синтеза отмечается только для рецепторного антагониста IL-1Ra. Заключение. Показано, что иммунный ответ при клещевых инфекциях запускается сразу после заражения человека, и уже в первые 2-5 дней можно обнаружить изменения в концентрации основных цитокинов в плазме крови.</p></abstract><trans-abstract xml:lang="en"><p>Background. Early detection of tick-borne pathogens in blood samples of infected people prevents the disease before clinical manifestations using antibiotic and immunoglobulin treatment. As far as tick-borne diseases are associated with significant activation of innate immune response, the changes in the cytokine profile soon after a tick bite could be used as an indicator of early tick-borne infection. Aims. The goal of this study was to characterize the production of cytokines during first 2-4 days after a tick bite in asymptomatic people infected with tick-borne pathogens. Materials and methods. The infection of tick-borne encephalitis virus, B. burgdorferi sensu lato, A. phagocytophilum and E. chaffeensis / E. muris was detected in blood of bitten humans using appropriate commercial real time RT-PCR and ELISA assays. Concentration of 14 cytokines in plasma of 89 infected and 45 non-infected people was established using quantitative ELISA kits. Results. Between 2nd and 4th days after tick bite, the prevalence and concentration of certain cytokines in blood of infected people significantly differed from those of the control group. Bacterial pathogens exhibited very similar patterns of cytokine profiles with induction of IL-1a, IL-8 и IFN-a and suppression of SOD, IL-1Ra и IL-17A. For virus infection the increased concentrations of IL-1 a, IL-8, IL-10, IL-17A, IFN-y and SOD were detected. The only suppressed cytokine was IL-1Ra receptor antagonist. Conclusions. The results suggest that evaluation of innate immune response between 2nd and 4th days after the tick bite could be a useful tool for evaluation of the risk of tick-borne disease for the humans bitten by ticks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клещевые инфекции</kwd><kwd>клещевой энцефалит</kwd><kwd>иксодовый клещевой боррелиоз</kwd><kwd>моноцитарный эрлихиоз человека</kwd><kwd>гранулоцитарный анаплазмоз человека</kwd><kwd>образцы крови</kwd><kwd>цитокины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tick-borne infections</kwd><kwd>tick-borne encephalitis</kwd><kwd>Lyme disease</kwd><kwd>human monocytic ehrlichiosis</kwd><kwd>human granulocytic anaplasmosis</kwd><kwd>blood</kwd><kwd>cytokines</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">Бедарева Т.Ю., Попонникова Т.В., Вахраммева Т.Н.
