[Complex evaluation of the defense systems in patients with infiltrative pulmonary tuberculosis].

Patients with infiltrative pulmonary tuberculosis at its degenerative stage were examined for parameters of hemostasis, serum proteolytic inhibitors, immunity status and complement. In doing so, the following changes were detected: simultaneous intensification of plasma coagulability and fibrinolytic properties, sputum-induced increase in fibrinolysis; disproportion in the content of the main protease blockers (higher alpha 1-protease inhibitor and lower alpha 2-macroglobulin); T-lymphocyte deficiency; stimulation of the immunity humoral link; rise in the count of O-lymphocytes and higher concentration of the complement component C3. The correlation between the indices of the examined systems was observed, thus indicating the interdependence of the body defensive factors. The findings can be used in the clinical practice when pathogenetic drugs are chosen.
