Oxidative stress and total antioxidant status in acute leukemia at diagnosis and post remission induction phase.

This study evaluated the activity of superoxide dismutase (SOD1), glutathione reductase (GR) and total antioxidant status (TAS) in the hemolysate and sera of patients with acute leukemia (AL) at diagnosis, post remission induction phase and in healthy controls. However, total antioxidant status and glutathione reductase activities normalized after remission induction phase in acute myeloid leukemia (AML) only whereas levels of SOD were reduced but not achieved the normal level in acute lymphoblastic leukemia (ALL). TAS activity showed no difference in either sex among any subtype of acute leukemia but glutathione reductase level was significantly higher in female ALL patients. Activity of SOD was elevated in T-cell ALL and acute myelomonocytic leukemia however; no significant difference in the activity of GR and TAS was noted. Levels of antioxidant were reduced insignificantly in patients who achieved complete remission.
