Abstract
Description
Diaskintest (DST) in 541 patients (children and adolescents) who were observed in the tuberculosis dispensary of the Republic Uzbekistan, including 23 with TB disease, as well as the incidence of TB in children and adolescents who had TB contact. The results obtained confirm the high sensitivity (DST was positive in all patients with local forms of tuberculosis) and the specificity of DST (all children with post-vaccination allergy had a negative reaction to DST), which allows it to be used for differential diagnosis of post-vaccination and infectious allergies in children. The highest frequency of positive reactions to DST from TB risk groups was observed in the contact group (50.6%). In a significant number of patients (13 out of 26), contact with bacterial-releasing patients was detected only retrospectively, after TB disease was detected (1/2 of them had contact with patients who isolated multidrug-resistant MBT strains, 2/3 had a family contact).
