title: [Interferon-gamma and IgG antibodies to M. tuberculosis in the serum of patients with active pulmonary tuberculosis].
abstract: The above parameters in the sera from patients with active tuberculosis (n = 20) and healthy individuals (n = 16) were studied in parallel to examine the relationship and mutual effects of interferon-gamma (IFN-gamma) and IgG antibodies to Mycobacterium tuberculosis, as well as their relationship with some clinical and immunological features of tuberculous infection. The relative and absolute counts of CD4 and CD16 cells were additionally measured in these patients' peripheral blood. Patients with active tuberculosis were found to have significantly elevated serum levels of IFN-gamma, IgG antibodies and CD16 cells with the decreased count of CD4 cells as compared with the similar parameters in healthy individuals. There was no relationship of the serum level of IFN-gamma to the clinical features of tuberculosis. The serum level of IFN-gamma is likely to determine the interferonogenic activity of the causative agent itself.
