Abstract
Aim. To investigate and assess the concentrations of glutathione peroxidase, superoxide dismutase, catalase, vitamin A and vitamin C in Iraqi patients infected by chronic myeloid leukemia (CML).
Material and methods. Forty-eight Iraqi patients of ages ranged between (15-75) years took part in the current study. Enzymatic antioxidants (Gpx, SOD and CAT) and antioxidant vitamins (A and C) were estimated spectrophotometrically in blood sera of all patients according to age and sex variables, and then all clinical parameters were compared with healthy individuals (control groups).
Results. Evaluation of oxidant-antioxidant status. Glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT) enzymes concentrations recorded high significant decreasing (***p <0.0001) in blood serum of CML patients according to age and sex factors. Moreover, vitamins A and C showed a high significant decreasing (***p <0.0001) in their concentrations as measured in blood serum of CML patients with diverse ages and sexes. The GPx, SOD, CAT, Vitamin A and Vitamin C in the current study, are considered excellent biochemical markers for following the acuity of CML disease depending on age and sex variables.
Conclusion. The clinical significance of oxidative stress represented by lack of enzymes and vitamins in the current study was proven. Statistically significant differences were recorded and observed between patients and control groups depending on age and sex factors.
