Abstract
The current study was perfomed to investigate the representativeness of the basic and antigen induced levels of specific (IFN-y) and non-specific (IL-6) biomarkers for the diagnosis of tuberculous pleural effusion. Ninety-three samples of pleural fluid from patient with tuberculosis (TP) and non-tuberculosis (Non-TP) pleurisy were examined. Induction of the synthesis IFN-gamma by immunocompetent cells in pleural exudate was carried out by the recombinant protein CFP10-ESAT6 contained in the diagnosticum «DIASKINTEST» by our method (Patent RF, № 2664427; 2017). Serum and pleural fluid IFN-y and IL-6 levels were measured by enzyme-linked immunosorbent assay technique (enzyme-am-plified sensitivity immunoassay kits, Vector-Best reagent kit (Russia). Our results suggested that introduction of M. tuberculosis antigens into the pleural fluids samples of TP group caused a significant increase of the IFN-y levels compared to basic level, which were not observed in the Non-TP group. Detection of IFN-gamma antigen-induced level in pleural fluid is a promising method for the diagnosis of tuberculous pleurisy. We found no significant differences in the basic and antigen-induced levels of IL-6 in patients with TP and Non-TP pleurisy.
