[Immunological reactivity in adolescents with different manifestations of tuberculosis infection].

Immunological reactivity was investigated in 306 tuberculosis adolescents aged 13-18 years: 117 with a turn of the tuberculin reactions, 20 with tuberculosis running for more than 2 years in the presence of aggravating factors, 57 with active tuberculosis of the respiratory organs, 15 with attenuating active tuberculosis, 36 with clinically cured tuberculosis. 79 noninfected adolescents served control. Immunological reactivity was altered more appreciably and often (nonspecific declined but specific enhanced) in active tuberculosis, less significantly in cured tuberculosis. The least changes occurred in the turn of tuberculin reactions and in patients infected for more than 2 years. Cellular immunity underwent most pronounced changes.
