[Tuberculin diagnosis in children with a family history of allergy].

Abstract

Two hundred and eighteen Mycobacterium tuberculosis-infected children and adolescents aged 4 to 18 years were examined. Whether the patients and their relatives had a history of allergic reactions was ascertained. A complex of diagnostic studies is of great value in verifying the presence of concomitant allergic diseases. The rate of allergic reactions in the child's history does not itself determine the likelihood of development of allergic states. The Mantoux (tuberculin) test in allergic children does not lead to an exacerbation of the underlying disease at remission. The remission manifestations of paraallergy are noted in 15.8% of the patients with allergic diseases and in 42.9% of the children having allergic reactions in the history. This supports the quality of a follow-up and treatment by an allergist, as well as an adequate response to a Mantoux test with 2 TE of PPD-L in the bulk of allergic children. The use of antihistamines as preparation for the test allows an inference about true infection and the sensitivity to tuberculin in both the most of allergic patients and persons with a history of allergic manifestations.
