Background and Objective: Pre-eclampsia (PE) is a hypertensive gestational disease appearing during second trimester of pregnancy. Free radicals are released by the placenta in this condition that may cause oxidative damage. This study was designed to determine the serum ferritin (SF) levels in maternal blood, fetal umbilical cord blood and placenta and the changes associated with oxidative stress as well as cell apoptosis to understand the pathogenesis of PE. Methods: This cross-sectional analytical study recruited 60 pregnant females with severe PE and assigned into early and late onset PE groups. Another n = 60 cases of normal pregnant females with similar gestational weeks were selected in the control group. Maternal serum and fetal umbilical cord blood ferritin levels were determined by automatic biochemical immunoassay system. Reverse transcription real-time fluorescence, Western blot and colorimetry were used to determine mRNA expression levels of ferritin and ferritin heavy chain, relative expression of ferritin and superoxide dismutase, malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) levels, respectively. Results: Mean age was 30.89 ± 5.65 and 31.79 ± 5.06 years in early and late onset PE groups respectively. Serum uric acid and creatinine levels of both PE groups were significantly higher than the normal pregnant females. SF levels were also higher in the participants of PE groups. However, the mRNA and ferritin protein levels in placental tissue were significantly lower in PE groups while comparing to controls. The cleaved caspase-3 protein, GSH-Px and MDA levels were significantly higher in both PE groups (p < 0.05). Conclusion: The alterations in factors related to oxidative stress and cell apoptosis in placental tissue may be helpful to understand the pathogenesis of PE and may provide potential biomarkers for the diagnosis of PE. |
