ObjectiveTo determine the biochemical and oxidative stress parameters as biomarkers in preeclampsia.Study DesignCross-sectional analytical study. Place and Duration of the Study: Departments of Obstetrics / Gynaecology and Biochemistry, Quaid-e-Azam Medical College, Bahawalpur, Pakistan, from September 2022 to February 2023.MethodologyWomen with preeclampsia were selected based on blood pressure exceeding 140/90 mmHg and proteinuria levels exceeding 300 mg/24 hours or showing a +1 on a dipstick test. Normotensive pregnant women were selected as controls. Venous blood was taken and centrifuged, and routine biochemical methods were used to estimate serum lipid profile levels and minerals. The estimation of oxidative stress enzymes was carried out manually using special chemicals. Student's t-test and Pearson's correlation were applied to analyse the result.ResultsThe study included 228 subjects: 114 preeclampsia patients and 114 normal pregnant women as controls. The mean systolic blood pressure was measured at 166.25 mmHg and the diastolic blood pressure was 92.80 mmHg (p <0.001). All lipid profile estimations showed notable abnormalities, but the mean level of triglycerides (TGs) (214.90 ± 15.59 mg/dl) in preeclamptic patients was significantly elevated (p <0.05). In terms of minerals, all were deranged but magnesium (1.37 ± 0.35 mg/dl) and calcium (7.55 ± 0.45 mg/dl) were significantly decreased (p <0.05). All oxidative enzyme levels were increased (p <0.05) but malondialdehyde (MDA) with a mean level of 2.58 ± 0.40 nmol/ml was significantly elevated. The Pearson's correlation of these parameters with blood pressure also showed a positive association.Conclusion Total cholesterol triglyceride in the lipid profile, calcium and magnesium in minerals, and MDA in oxidative parameters were markedly deranged and exhibited significant associations with the severity of the disease, so could be used as disease biomarkers of preeclampsia.Key WordsPreeclampsia, Gestational hypertension, Proteinuria, Lipid profile, Minerals, Oxidative stress.
