Antioxidant defence was investigated in red blood cells (RBC) in 56 patients with 3 different haemoblastoses: polycythemia vera (PV), chronic myelogenous leukaemia (CML), chronic lymphoid leukemia (CLL) with and without anaemia, in 12 iron deficiency anaemia (A) patients and 50 healthy persons. The activities were determined of the following antioxidant enzymes: glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GSSG-R), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and MDA levels. Antioxidant defence is decreased and the level of lipid peroxidation are increased in RBC in all patients (PV, CML, CLL, A). Different changes were detected in the antioxidative defence between normal red blood cells and those formed from leukaemic cells clone. In normal RBC in anaemia (CLL, A) opposite deviation of G6PD and GSSG-R activities was observed. In RBC formed from leukaemic cell clone (PV, CML), a simultaneous significant increase in G6PD and GSSG-R activities was found, which indicated activisation of pentose phosphate pathways (PPP) in these pathologies; in anaemia they function less effectively.
