Background Pregnant women are more prone to oxidative stress. Iron deficiency anemia not only affects hematological parameters but also disturbs body oxidative balance, which impairs pregnancy outcome. Besides, iron therapy may generate harmful oxygen species. Objectives The aim of this study was to investigate the effect of the nature of oral iron supplementation (ferrous vs. ferric) in pregnant women with iron deficiency on oxidative stress and its correlation with peripheral systemic inflammatory response markers. Patients and methods A clinical trail study involves study included 30 healthy and 50 anemic pregnant women in their 20th-36th gestational weeks who fulfilled the inclusion criteria. They were randomly distributed to receive either ferrous sulfate or ferric polymaltose complex. Outcome was assessed after 8 weeks of iron supplementation and included hematological parameters, neutrophil : lymphocyte ratio, platelet : lymphocyte ratio, mean platelet volume, serum malondialdehyde (MDA), total antioxidant capacity (TAC), iron, and ferritin. Results Anemic pregnant women have increased oxidative stress with high levels of MDA and TAC, both at baseline and following iron supplementation (P < 0.001). Following 8 weeks of iron supplementation, there were a significant increase (P < 0.001) in hemoglobin and serum ferritin, and a significant decrease (P < 0.001) in the peripheral inflammatory markers neutrophil: lymphocyte ratio, platelet: lymphocyte ratio, mean platelet volume, and absolute lymphocyte counts. Conclusion Iron polymaltose complex was as effective as ferrous sulfate as both were able to correct hematologic parameters in parallel to a decrease in MDA and peripheral inflammatory markers together with an increase in TAC levels to maintain oxidative balance.
