BCG-teste em crianças sadias previamente vacinadas com a BCG Moreaux-Rio de Janeiro

Abstract

 

BCG-test reaction was carried out in 91 non-tuberculous children between 2 and 11 years old, who had received BCG vaccination during the first six months of life to critically evaluate the usefulness of this test in Pediatric practice. The BCG-test profile of the vaccinated group was shown to have a unimodal distribution, varying from 3 to 17 millimeters, with a median of 6 millimeters. It was demonstrated that the degree of reaction decreases with time. Nevertheless, false-positives could be expected in a significant percentage when reactions larger than 10 millimeters are considered as a cutoff. The specificity can be increased using only reactions with diameter equal or greater than 15 millimeters as an indicator of tuberculous disease.
