Choice of informative biomarkers for diagnostics of Mycobacterium tuberculosis infection and differential diagnostics of active tuberculosis (TB) of lungs and latent tuberculosis infection (LTBI). Materials and methods. 54 tuberculosis patients, 47 contact by TB individuals and 43 healthy donors were examined. All the individuals included into the study had QuantiFERON-TB Gold In-Tube (Cellestis, Аustralia) carried out. Values of spontaneous (NIL) and antigen-induced (AG) production of10 cytokines (EGF, MIP-1p, VEGF, IL-2, IL-4, IL-6, IL-1a, IFN-a2, TGFa, TNFa) as well as sIL-2Ra and sCD40L using XMap technology were measured. IP-10 level was also determined in 48 individuals by using EIA. Results. 6 out of13 biomarkers distinguished active TB and LTBI. As a result of construction of a decision tree in JMP 9.0 program 3 most significant markers were selected. Use of combination of IFNy Ao -NIL, TGFa NIL and IL-6 AG cytokines allowed to divide TB patients and contact individuals with sensitivity of 96.3% and specificity of 80.7% (AUC=0.9). We also observed very high levels of IP-10 and IL-2 that correlated with IFNyag -nil (r=0.71 and 0.79, respectively). Conclusion. IL-2 and IP-10 as well as IFNy may be used as helpful biomarkers as a first stage for diagnostics of (M.tb.) infection. At the second stage determination of IL-6, IFNy and TGFa for differential diagnostics of active TB and LTBI is proposed.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Выбор информативных биомаркеров для диагностики инфицирования Mycobacterium tuberculosis и дифференциальной диагностики активного туберкулеза (ТБ) легких и латентной туберкулезной инфекции (ЛТБИ). Материалы и методы. Обследованы 54 больных туберкулезом, 47 контактных по ТБ лиц и 43 здоровых донора. Всем лицам, включенным в исследование, выполнен «QuantiFERON-TB Gold In-Tube» («Cellestis», Австралия). Измерены значения спонтанной (NIL) и антигениндуцированной (AG)про-дукции 10 цитокинов (EGF, MIP-1p, VEGF, IL-2, IL-4, IL-6, IL-1a, IFN-a2, TGFa, TNFa), также как и sIL-2Ra и sCD40L с использованием технологии XMap. Также определяли уровень IP-10 у 48 чел методом ИФА. Результаты. Шесть из 13 биомаркеров различали активный ТБ и ЛТБИ. В результате построения дерева решений в программе JMP 9.0. были выбраны три наиболее значимых маркера. Использование комбинации цитокинов IFNy AG-NIL, TGFa NIL и IL-6 AG позволило разделить больных ТБ и контактных лиц с чувствительностью 96,3 % и специфичностью 80,7% (ППК=0,9). Мы также наблюдали очень высокий уровень IP-10 и IL-2, который коррелировал с IFNy AG-NIL (r= 0,71 и 0,79 соответственно). Заключение. IL-2 и IP-10 также, как и IFNy, могут использоваться в качестве полезных биомаркеров в качестве первого этапа для диагностики инфицирования M. tuberculosis. На втором этапе предлагается проводить определение IL-6, IFNy и TGFa для дифференциальной диагностики активного ТБ и ЛТБИ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>QuantiFERON-TB Gold In-Tube</kwd><kwd>lung tuberculosis</kwd><kwd>multiplex analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>туберкулез легких</kwd><kwd>мультиплексный анализ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Васильева Е.В., Вербов В.Н., Никитина И.Ю. и др.
