Abstract
Conflicting data are available regarding oral iron therapy in iron deficiency (ID), iron deficiency anemia (IDA) and its relation to DNA damage, oxidative stress and antioxidant markers. Our aim was assessment of DNA damage, oxidative stress and anti-oxidant markers in children with ID and IDA before and after low dose iron therapy. The study was conducted in two stages, first stage was assessment of DNA damage using comet assay, malondialdehyde (MDA) and anti-oxidant enzymes levels (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) & total antioxidant capacity (TAC) in thirty-nine children with IDA, forty-five children with ID without anemia and sixty healthy controls. Second stage was assessment of previous markers together with hematological response following oral therapy with 10mg/day ferric ammonium citrate for 8weeks. Before treatment, there was no significant difference between the three groups regarding MDA, GPx, SOD, CAT and TAC. A significant increase was detected in the DNA damage in the 2 groups compared to control (p < 0.005). Following iron therapy, hematological parameters was improved together with a significant increase in GPx (P = 0.04), SOD (p = 0.002), TAC (P = 0.001) and non-significant reduction in DNA damage in IDA group. There was a significant increase in SOD (p = 0.001) & TAC (p = 0.001) and significant decrease in DNA damage (p = 0.001) in ID group. Low dose iron therapy could be sufficient to improve antioxidant status and DNA damage together with correction of hematologic indices.
