Quantitative assessment of tumor necrosis factor induction by the whole blood cells ex vivo, in the presence of Mycobacterium tuberculosis antigens
Abstract
We studied an efficacy of whole-blood method of tumor necrosis factor-alpha (TNF-alpha) induction in the presence of Mycobacterium tuberculosis antigens (tuberculin PPD and a mixture of specific recombinant ESAT-6 and CFP-10 antigens), for differential diagnosis of active tubercular infection. A customized test system with immunoenzyme assay was developed, to quantify TNF-alpha in plasma samples. Based on findings of blood sample investigations in 46 adolescents with tubercular infection (latent infection) and active pulmonary tuberculosis, the study demonstrated the possibility of differentiation between active and latent tubercular infection, using ESAT-6 and CFP-10 antigens as TNF-alpha inducers.
