IMMUNE PROFILE AND ENZYMES ACTIVITY STATE IN BLOOD LYMPHOCYTES IN PATIENTS OF DIFFERENT STAGES ACUTE LYMPHOBLAST LEUKEMIA

Abstract

Abstract. We studied immunological state and activity of enzymes in blood lymphocytes from the patients at different stages of acute lymphoblastic leukemia. We have revealed that immune state in all the patients was characterized by decreased contents of T-lymphocytes. Upon first attack of the disease, they showed a decrease in CD4+cells, as well as increased concentration of IgM and IgG. During remission, we have found the lowest values of all the parameters under study. In relapsing patients, high content of NK-cells, and imbalance between the main Ig classes were noted. When studying metabolism of lymphocyte, it was revealed that, in first attack and relapse phase, both intensity of anaerobic glucose oxidation, and levels of macromolecular synthetic reactions were decreased. In remission, all these processes did recover to normal range. At all stages of disease, glutathione reductase activity was found to be decreased in blood lymphocytes. (Med.
