[Specific features of immunity in patients with different forms of pulmonary tuberculosis]

The cellular immunity was studied in 59 patients with pulmonary tuberculosis. The development of tuberculous infection was ascertained to be accompanied by decreases in the relative counts of CD9, CD8, and CD72 lymphocytes, as well as monocytes, expressing class II histocompatibility antigens (DR). The patients with tuberculosis were found to have suppressed proliferative T-cell activity and IL-2 production, moderately decreased IL-1 production and increased TNF alpha secretion.
