Interrelationship Between Markers of Oxidative Stress, Inflammation and Hematological Parameters Among Preeclamptic Nigerian Women

BACKGROUND Preeclampsia is a multifaceted pregnancy-related disorder affecting women and fetuses. A link between preeclampsia, oxidative stress, and inflammation has been suggested. This study evaluated the interrelationship between biomarkers of oxidative stress, inflammation, and hematological parameters among preeclamptic Nigerian women. MATERIAL AND METHODS A cross-sectional study was conducted among 49 preeclamptic and 50 normotensive healthy pregnant women. Blood samples were obtained after 20-week gestation in all participants. Levels of superoxide dismutase (SOD), catalase, glutathione (GSH), malonaldehyde (MDA), total protein, high-sensitivity C-reactive protein (hs-CRP), and cardiac-specific troponin I (cTnI) were determined by spectrophotometric and ELISA techniques. FBC, prothrombin time, and activated partial thromboplastin time were determined using an auto-analyzer, Quick's one-stage, and Proctor's and Rappaport's modification methods, respectively. RESULTS The mean SOD (0.051±0.050 vs. 0.073±0.047, p 0.029), catalase (2.62±1.93 vs. 8.48±4.40, p
