title: [Relationship between serological diagnosis (ELISA) and severity of pulmonary tuberculosis in children].
abstract: Forty eight children from 0 to 13 years old were submitted to the enzyme-linked immunosorbent assay (ELISA) serological test with a view to detect anti PPD IgG antibodies, for diagnosis of pulmonary tuberculosis and to establish the relationship between immune response and radiological gravity of pulmonary tuberculosis (mild, moderate and severe). There were 29 children with pulmonary tuberculosis and 19 children without tuberculosis. The median ELISA optical density were: 0.098 in children with primary complex (mild); 0.092 in children with pneumonic pattern (moderate) and 0.134 in children with miliary tuberculosis (severe). These data show higher positive serological test results in severe forms of pulmonary tuberculosis (p = 0.0007).
