Preeclampsia is a multisystemic disorder specific to human pregnancy. It is common and major complication, characterized by hypertension, proteinuria and oedema. This clinical condition adversely affects the mother and the foetus. The causative factors remain poorly understood. Oxidative stress is implicated in preeclampsia which could provide the linkage between decreased placental perfusion and the maternal syndrome. Pregnancy has also been associated with depressed cell mediated immunity. The increase in activity of adenosine deaminase (ADA) in preeclamptic women compared to normotensive pregnant women is reported in earlier studies. The main objective of the present study was to correlate the adenosine deaminase activity with the antioxidant status in preeclamptic pa-tients. The study groups aged between 20 – 35 years included 20 normotensive primigravida wom-en and 20 primigravida diagnosed as preeclampsia in their last trimester. The control group included 20 healthy nonpregnant women volunteers of the same age group. The diagnosis of preeclampsia was made by a gynecologist at Lady Goshen Hospital. The adenosine deaminase activity and antioxidant status in the form of superoxide dismutase (SOD), glu-tathione (GSH) and total antioxidant activity (TAA) were measured. The extent of oxidative stress was estimated by measuring plasma malondialdehyde (MDA) levels. The comparison of MDA between controls and preeclamptic patients showed significance (p 0.000). The total antioxidant activity (TAA) between the controls and preeclamptic pa-tients showed significance (p 0.000). However, ADA activity did not show statistical signifi-cance among the different study groups. The ADA activity may not be significant due to other systemic causes such as anemia and malnutrition.
