[Clinico-immunological substantiation of the use of rifampicin in the combined therapy of adults and adolescents with destructive pulmonary tuberculosis].

The effect of various doses of rifampicin on intensity of rosette formation was studied, and the immunological criteria for selective use of the drug in combined specific chemotherapy of extended destructive tuberculosis of the lungs were determined. It was shown that differential use of rifampicin with an account of its administration multiplicity and route promoted a decrease in the hospitalization terms and increased rate of discontinuation of tubercle bacilli isolation and cavern healing. The clinicoroentgenological findings were confirmed by the immunological tests characterizing various elements of the immunity system in patients.
