THE FEATURES OF SURFACE PHENOTYPE OF BLOOD LYMPHOCYTES IN THE PATIENTS WITH TUBERCULOSIS

Abstract

Abstract. Parameters of peripheral blood lymphocytes subpopulations have been studies in the patients with extensive destructive pulmonary tuberculosis caused by drug-sensitive or drug-resistant Mycobacterium tuberculosis before and in the course of specific anti-tuberculosis chemotherapy. It was revealed that in the patients before treatment, a marked immunosuppression takes place, being characterized by decrease of total T-lymphocytes and their basic regulatory and effector subpopulations. E.e., an increase in CD20+-, CD25+- and CD95+cells was observed. The completion of intensive anti-tuberculosis chemotherapy is not accompanied by correction of lymphocyte subpopulations. By contrary, in the patients with drug-sensitive pulmonary tuberculosis M. tuberculosis a sharp increase in CD95+-lymphocytes is registered. After undergoing a full course of therapy a well-noted tendency to normalization of T-lymphocytes (CD3+) quantity, as well as is regulatory populations (CD4+ and CD8+) were found. The level of CD95+-lymphocytes remained increased in the patients with pulmonary tuberculosis caused by drug-resistant M. tuberculosis.
