Outline of Final Research Achievements |
The challenge of development of useful new diagnostic methods for tuberculosis infection. 1)In order to increse the sensitivity and specificity, we measured the colony forming unit of IFN-γ produced by the stimulation of Mycobacterium tuberculosis (MTB)-specific antigen after the isolation of monocytes using the clinical specimens from the inflammation sites. As a result, when we used pleural effusion, highest sensitivity was obtained comparing to other diagnostic methods. 2)We measured several cytokines and chemokinesin the supernatant stimulated by MTB-specific antigens. IP-10 and MIG were useful to differentiate active TB disease and other diseases as well as IFN-γ. On the other hand, IL-2 showed most poor results. If the new diagnostic kit which can be measured IP-10 and IL-2 with IFN-γ simultaneously was developed, it may be possible to discriminate active TB disease and latent TB disease or healed TB disease in future.
