Features Immunodiagnostic Local Forms of Tuberculosis in Children

Abstract

The 100 children with local forms of tuberculosis (LFT) were examinated used by the method of continuous sampling. The results of the LFT immunodiagnostic with the Diaskintest (DST) in the children were evaluated. Diaskintest were started applying in Samara one of the first from Russia. The confirmation of the tuberculosis in children with LFT was done in 99% of cases by the positive skin tuberculin tests and in 84% by Diaskintest positive. It is shown that Diaskintest can not be taken as an absolute diagnostic criteria for the diagnosis of the tuberculosis. Were noted that the FGA stimulated IFN-γγ production level were significantly reduced (1,7 times), the DST stimulated IFN-γγ production level were elevated more than 18 pg/ml in the children with negative skin Diaskintest. This observation shows that the issues in the fields of tuberculosis immunodiagnostic require further investigations.
