Abstract
T-cell subpopulations were evaluated by several recent methods in 38 tuberculosis patients (24 active and 10 quiescent cases of pulmonary tuberculosis; two of miliary and two of active extra-pulmonary tuberculosis) before and during rifampicin (RMP) treatment. There was a significant reduction in the total number of T cells (E-RFC and OKT3+ cells) and of helper T cells (OKT4+) coinciding with an increase in the number of suppressor T cells when the 38 tuberculosis patients were compared with 21 healthy control subjects. When the changes of T-cell subpopulations in groups of subject and patients with different clinical forms of the disease were analysed, these changes could be clearly shown with both sets of assays (receptor assays and monoclonal antibody assays) among those with the active pulmonary form of tuberculosis while similar changes could be demonstrated only by one or the other assay among those with the other forms of the disease. The effects of one month of RMP treatment on these parameters were much more obvious among the clinically active patients than the quiescent patients, i.e. a recovery of total T cells from a low pre-treatment to a near normal level accompanied by a significant reduction in the number of suppressor cells (OKT8+). In fact, among quiescent patients the number of suppressor cells (as TG) appeared to rise further with RMP treatment.
